New Policy on BMI Use Will Change How Physicians Approach Diagnoses and Care

The Body Mass Index – or BMI – table was created in the mid-1800s, and for the last several decades has been viewed as the choice tool to diagnose obesity. However, the American Medical Association (AMA) recently issued a policy clarifying the role of BMI after taking a comprehensive look at both its benefits and limitations as a diagnostic tool. In short, the new policy urges physicians to use BMI only in conjunction with other measures of risk and recognizes the historical shortcomings of the oft-used formula. Lisa Diewald, MS, RDN, LDN, is the program manager of the MacDonald Center for Nutrition Education and Research with Villanova’s M. Louise Fitzpatrick College of Nursing. She applauds the AMA for embracing a more holistic approach to weight and health in individuals. “This is a huge step forward and I think it will ultimately lead to better health care and an improved practitioner-patient relationship,” Diewald said. To understand why, one must first understand the history of BMI’s use. The formula that spits out the number we have all come to understand as our BMI considers a person’s height and weight. It was developed in the mid-19th century by a Belgian sociologist to measure the socially ideal person. The modern term and application came about in the 1972 and has been a routine measurement ever since because it is easy, fast, costs nothing and in some cases, said Diewald, does correlate with body fat. But in recent years, large scale studies have exposed some of the limitations of the measure, building to the point where they needed to be weighed against the overt benefits. For starters, BMI does not measure body fat – or adiposity – directly. Adiposity, per Diewald, is more closely associated with health risk than BMI. “For this reason, health risk for some individuals with normal BMI but high body fat has been underestimated, and some with high BMI but normal body fat levels have been overestimated,” she said. Nor does it “differentiate between muscle, bone and body fat, or distribution of fat on the body,” Diewald said. “We know that all these factors can influence health and chronic disease risk.” Other comorbidities or chronic conditions that wouldn’t show up on a BMI chart alongside a number in the “normal” range can also impact health. Conversely, there are health conditions that might be incorrectly assumed just because a BMI is high. “Not every person with a high BMI experiences these chronic conditions, so developing a more holistic approach can lead to better assessment, treatment and outcomes,” Diewald said. Another shortfall she pointed out was its failure to factor in gender, race, body composition, ethnicity or physical activity level. Think back to the origins of the chart, intended to be a social standard created in Europe nearly two hundred years ago. “BMI tables were originally designed in the 1800’s using a population of white men,” Diewald said. “Understandably, at one point in time it was all we had to evaluate weight status, but it may not be accurate to use this standard alone with all groups of people.” These societal, gender and racial/ethnic factors led the AMA to explicitly cite “historical harm, use for racist exclusion and because BMI is based primarily on data collected from previous generations of non-Hispanic white populations” in the new policy on its clinical use. Additionally, the policy addressed the differences in body composition across genders, races and ages that were not being considered. There is also an ignored mental component in its use to diagnose obesity, which can lead to avoidance of doctor visits and, in turn, further physical issues. “Obesity is a multifactorial, complex condition and addressing it with individuals needs to be done with empathy and sensitivity, beginning with how it is measured,” Diewald said. “There are numerous factors influencing weight well beyond simply food intake, physical activity level and BMI, so it is important for practitioners to recognize that and communicate this to patients. “It is extremely difficult for people with higher weight to be told that they have a high BMI and simply need to eat less and move more. When BMI is used as the sole indicator of weight status, this can be psychologically damaging. We know that many who have been told to lose weight simply based on a high BMI may avoid going to the doctors for routine medical visits and skip necessary preventive care.” It will not be easy, she said, to move away from a method used for so long that has been ingrained as a part of a routine medical visit, but Diewald thinks utilization of the tool in conjunction with other assessments is the best way put this new policy to practice. She advocates for measures such as “Using BMI as only one of several indicators of chronic disease risk, asking permission to discuss weight and health risk, [and] using shared decision-making between practitioners and patient to determine course of treatment.” Education is also paramount to proper assessment of weight-related health risks. “Education cannot stop with physicians, however,” she said. “I think this provides an excellent launching pad for enhanced collaboration among health professionals such as dietitians, nurses, nurse practitioners, physician’s assistants and others involved in providing care, nutrition counseling and lifestyle modification support to patients… Doing this can better fine tune recommendations for treatment, leading to improved outcomes.”

Predicting the post-pandemic desires for the Latin music industry

Coachella, identified as a mega-festival universe, decided on a diverse 2023 roster with artists like Becky G, Kali Uchis, and Rosalía. Bad Bunny, last year’s most-streamed global artist, made history as the festival’s first Spanish-language headliner. It also marked the first year since Coachella’s founding in 1999 that none of the headliners were white. José Valentino Ruiz-Resto, an assistant professor in the School of Music at the University of Florida, co-authored a paper for the Journal of Arts Entrepreneurship Education, which focused on how the music industry would evolutionarily change after the pandemic and ultimately predicted the 2023 Coachella trend. “The rise of Latin artists/headliners at festivals like Coachella is really a reflection of what has been happening in the music industry for the past two decades,” said José Valentino Ruiz-Resto who is also the program coordinator of Music Business & Entrepreneurship at UF. Ruiz-Resto’s research showed that the post-Covid era music industry would encourage more people to stay home and listen to music digitally, but the traditional Latin music experience is an outlier to this. The world-renowned multi-instrumentalist explains, "In order for concerts and festivals to maintain success, they needed to branch out to other markets to bring in those people who were still very much passionate about experiencing music in a live context.” Although this shift was initiated by the pandemic, it has been patiently anticipated by Ruiz-Resto for over 23 years, starting with the founding of the Latin Grammys in 2000. “Because the amount of production within the Latin recording academy is almost equivocal to that of all of the other genres in the American market combined. Latin music is the No. 1 meta genre in the music industry in terms of sales and fan support,” Ruiz-Resto, now a four-time Latin Grammy Award winner, said. Ruiz-Resto's data predicted the need for a stronger focus on the Latin music enthusiasts who still actively go to concerts like Coachella, “In order for Coachella to ultimately succeed in the post-Covid era and attract people, they needed to bring in artists like Bad Bunny.” This historic Coachella moment followed an announcement from the Recording Industry Association of America, stating that Latin music revenues in the United States were at an all-time high, exceeding over $1 billion in 2022. All of this was no surprise to Ruiz-Resto, who observes, researches and directly participates in the Latin music industry. “Now bigger shows are catching up to what has been the largest-selling music market for years. It’s a testament to how positively Latin American cultures are inspiring listeners across the U.S.” By Halle Burton

ChristianaCare Rated as One of the United States’ Best Hospitals by Newsweek for Fifth Consecutive Year

ChristianaCare ranked as 81st best hospital in the United States and the only health system in Delaware to make the list For the fifth consecutive year, ChristianaCare has earned a spot in Newsweek’s exclusive list of the World’s Best Hospitals – United States, recognized for consistently being at the forefront in care, research and innovation. “Receiving this honor year after year is a testament to the work ChristianaCare caregivers do each day to create health together so that every person can flourish,” said ChristianaCare President & CEO Janice E. Nevin, M.D., MPH. “At its core our mission is a simple, yet profound, one. We take care of people. And I am so proud of everyone in this organization for what five-straight years of being called one of the World’s Best Hospitals says about the exceptional quality of the care we provide.” Headquartered in Wilmington, Del., ChristianaCare ranked 81st in the United States in the annual list that ranks 2,300 hospitals in 28 countries. “ChristianaCare has gained a global reputation thanks to our unwavering focus to provide expert, high-quality care,” said Kert Anzilotti, M.D., MBA, chief medical officer at ChristianaCare. “This award belongs to all our caregivers, who continuously seek new knowledge, are true to their word and are committed to delivering exceptional care to every patient we serve.” Compiled by Newsweek and the global data firm Statista, the lists are based on the following data sources: Recommendations from tens of thousands of doctors, health care professionals and managers across the world. The survey asked participants to recommend hospitals in their own country as well as in other countries. The survey did not permit recommendations of the health professional’s own hospital. Patient surveys originating from publicly available data that included areas such as their general satisfaction with the hospital and their satisfaction with their medical care. Hospital quality metrics such as data on the quality of care for specific treatments, data on hygiene measures and patient safety, and data on clinician-patient ratios. The Patient Reported Outcome Measures (PROM) surveys, which are standardized, validated questionnaires completed by patients to measure their well-being and quality of life. The recognition by Newsweek echoes other quality recognitions that ChristianaCare has received during the past 12 months: For the third consecutive year, Healthgrades named ChristianaCare one of America’s 50 Best Hospitals for 2023. Healthgrades also ranked ChristianaCare as one of America’s 50 Best Hospitals for five service lines: cardiac care, coronary intervention, joint replacement, spine surgery and gastrointestinal surgery. For the seventh consecutive year, the College of Healthcare Information Management Executives named ChristianaCare a Most Wired Health Care Technology Leader. U.S. News & World Report rated ChristianaCare as the No. 42 hospital in the nation for obstetrics and gynecology and a High Performing Hospital for Maternity. U.S. News & World Report also rated ChristianaCare as high-performing in orthopedics. For the second consecutive year, Forbes ranked ChristianaCare as one of the Best Employers for Diversity and Inclusion in the United States. The Human Rights Campaign Foundation gave ChristianaCare’s Christiana Hospital and Wilmington Hospital the top score in the Human Rights Campaign Foundation’s most recent Healthcare Equality Index.

Expert opinion: Tories promise spending for the creative industries but need to invest in education first

If you’re looking for comment on this week’s announcement about government’s proposed £50bn investment in creative industries we have a design expert available. Dr Tim Whitehead is associate dean and senior lecturer, engineering and technology, Aston University. He believes that although the Tory's promise spending for the creative industries they need to invest in education first. His full response is attached and below: “This week the government announced a plan to boost the creative industries by £50bn by 2030 and invest £77m in funding for the sector. “This news is fantastic and long overdue. The UK design economy contributes £97.4bn GVA and for every £1 invested in design we see a return of £4 to the wider economy. “The creative sector is a major British export with film, TV, music being some of the biggest exports. However, we also have physical products; If you’ve ever used an iPhone, a Dyson or ridden on a London double decker bus then you’ve used world class British design. “The funding is welcome, however we really need investment in our schools to teach creativity and align this with recent announcements in maths education. “The majority of our most successful designers / creative engineers started with Design and Technology at school. “Between academic years 2009-10 and 2021-22, the proportion of pupils taking Design and Technology GCSEs fell from around 42% to 27% in all schools in England. With only a minor increase in pupils taking Art and Design GCSE which increased from 27% to 29% over the same period. “There is a big gap here, and we really need to ensure that children have access to a creative education as school. “By embedding creativity into the next generation it will help foster new creative engineers data scientists etc. and the next Dyson.” Dr Tim Whitehead, associate dean and senior lecturer, engineering and technology, Aston University For inquiries contact Nicola Jones, Press and Communications Manager, on (+44) 7825 342091 or email: n.jones6@aston.ac.uk

Researchers seek to apply nanoparticle drug delivery to coral wound healing

Coral reefs are the foundation of many aquatic ecosystems and are among the ocean’s most vulnerable inhabitants. While natural processes, like animal predation and storms, frequently damage coral, man-made causes, like ship collisions and global warming, destabilize these environments beyond their ability to recover. Researchers like Nastassja Lewinski, Ph.D., associate professor of chemical and life science engineering, are working to understand how corals heal in order to aid the restoration of these fragile ecosystems. They also seek partnerships with stakeholders that can support coral preservation by applying this research to industry practices and providing funding for continued research. “Coral ecosystems are vital to human life,” Lewinski said, “When there’s a high-intensity storm, reefs can absorb the impact and reduce the damage we see on land. They’re also important to the aquatic food web and serve as the foundation to many foods we eat.” Discovering the limits of coral healing is part of Lewinski’s work. Ideal water temperature for coral is 25 degrees Celsius, so research is conducted at the ideal temperature and elevated temperatures of 28 to 31 degrees Celsius, the projected water temperatures influenced by global warming. Successive imaging of wound closure in these conditions builds an understanding of the rate of closure during healing. “We’re looking to understand the mechanics of healing,” Lewinski said, “Some of what we’ve found suggests a process similar to human healing. We want to understand the actors in this process at a cellular level and what their role is in repairing tissue.” These observations inform the mathematical, cell-based wound healing model developed by Lewinski’s collaborators, Angela Reynolds, Ph.D. and Rebecca Segal, Ph.D., both professors in the Department of Mathematics and Applied Mathematics in VCU’s College of Humanities and Sciences. Similar to humans, corals have been documented as following the same four stages of the healing process. These stages include: 1) coagulation to close the site of injury, 2) infiltration with immune cells to ward off infection, 3) cell migration and proliferation and 4) scar remodeling. “With our observations and a mathematical model, the next step is to collect data on the cellular dynamics of the healing process,” Lewinski said, “We want to observe what kinds of cells enter the wound area and what functions they perform during healing.” Fluorescent tagging is used to mark specific cells so they may be observed entering the wound area when healing occurs. Because corals are naturally fluorescent, the selection of the fluorescent tags must take this into account. Phagocytic properties allow immune cells to engulf and absorb bacteria and other small cells, in this case the fluorescent particles being used to tag immune cells. Nutritional variables are also being considered within the experiment. Corals derive energy from consuming small organisms and their symbiotic relationship with algae colonies. Modifying nutritional balance in the lab emulates the coral’s participation in the food web, where accessibility to vital nutrients could impact healing. Developing a nanoparticle drug-delivery system designed to deliver molecules to speed wound healing is the culmination of this research. Lewinski hypothesizes the delivery system would promote an energy-burning state within the corals that could result in increased healing. This is among a few examples of harnessing nanotechnology for safeguarding coral reefs, which are discussed in a recently published comment in Nature Nanotechnology. “The research we’re doing on wound healing in corals is the start of something bigger,” Lewinski said. “Our goal is to create a center dedicated to engineering new technologies for corals. We want to find partners who can translate our research findings to practice, helping preserve coral reefs and the vital resources they provide.” Through this consortium, newly-developed science can be disseminated more effectively within each partner’s respective industry. The result: a renewed commitment to aquatic sustainability and the protection of vital coral ecosystems.

Aston University research to shine a light on the experience of financial uncertainty among UK households

Experts from the Centre for Personal Financial Wellbeing will examine the daily financial struggles of low to moderate income UK households The Real Accounts project will capture day-to-day financial fluctuations, understanding household money management strategies It is hoped the results will help inform policy and market innovation and debate. New research by the Centre for Personal Financial Wellbeing at Aston University will shine a light on the real day-to-day experience of financial uncertainty among UK households and help inform policy and market innovation and debate. The Real Accounts project will build an in-depth understanding of the lived experience of financial uncertainty among low to moderate income households across the country. Believed to be the first of its kind in the UK and in contrast with the snapshot data achieved by annual surveys, this long-term study will provide a fully joined-up view of household finances, capturing the day-to-day, week-to-week ups and downs, working with households to understand the situations they face and the strategies they use to manage their money. The project will be a collaboration with Nest Insight and the Yunus Centre for Social Business and Health at Glasgow Caledonian University. Experts will use a research data collection app that has been custom designed by Moneyhub to capture real-time income and expenditure transaction data over six months for a sample of around 50 low to moderate income households, combined with monthly interviewing. Professor Andy Lymer, director of the Centre for Personal Financial Wellbeing at Aston University, said: “We are really pleased to be part of this innovative project, directly focusing on real experiences of managing financial volatility and the impact that has on broader aspects of wellbeing. Too little is currently known about the scope and scale of income and expense volatility experienced by UK households. This research is really timely given people are currently facing the very significant impact of the cost-of-living crisis and often enormous uncertainty about both their incomes and their expenditures. The outcomes of this work will generate deeper understanding of what it means to experience financial challenges in reality and over sustained periods of time. It will contribute to finding better ways to help people in their everyday lives and is a perfect fit for the focus of our Centre that seeks to deepen our understanding of what matters in creating personal financial wellbeing.” Sope Otulana, head of research at Nest Insight, said: “As the rising cost of living continues to impact households across the country, and levels of household debt climb, this research is more crucial than ever. The project aims to shine a light on exactly what it is like for households today managing volatile income and expenditure, sharing their first-hand stories. While large income and expenditure datasets track individuals and their behaviour out in the world, this research puts individuals back into the contexts where their financial lives play out, focussing on the overall household – partners, parents, siblings, friends and other social connections. It will look beyond the balance sheet to also analyse social, environmental, and health factors, as well as other dynamics that can come into play and affect household finances. The research will identify trends but also capture the variation within households, recognising that there is no ‘average’ household circumstance or experience.” Alex Christopoulos, Aviva Foundation lead and senior strategic adviser and consultant, said: “Millions in the UK are struggling and worried about money. The Real Accounts research provides us with an opportunity to understand how these households are managing to get by day-to-day; the choices they make, the strategies they take and the knock-on effects this has on other areas of their life. In uncertain times, we need to better understand how people deal with fluctuations in their incomings and outgoings – and what kinds of financial support and services might enable them to build a buffer, and a plan, to deal with today’s pressures, as well as what tomorrow may bring. The Aviva Foundation is proud to be supporting Nest Insight and its partners to deliver to the Real Accounts research.” Samantha Seaton, CEO of Moneyhub, said: “It is only when we have in-depth and holistic data on a person's or household’s finances that we can truly know and begin to understand the impact of the rising cost of living. This can only be successfully achieved by bringing all of an individual's or household’s financial data together in one place, from every-day spending to long-term projects such as buying a property and saving for retirement. At Moneyhub, we’re absolutely delighted to be providing our cutting-edge technology to enable Nest Insight and its partners to collect and analyse this crucial data. We know from our own users the pressure that the current economic situation is placing on them, with many unable to save resorting to borrowing to get by each month. Having thorough data and insight will enable any solution to be highly personalised in its approach and have a much more positive impact on those that require it most. Ultimately the more real-time financial data points, the more informed the decisions can be. It has always been our purpose at Moneyhub to improve financial wellness, and this project is just one example of how we’re using Open Finance to do exactly that.” You can find out more about the project here.

Aston University teams up with nationwide accountancy firm to boost audit practices with data analytics

The management Knowledge Transfer Partnership (mKTP) with Beever and Struthers will help drive the firm’s digital transformation The 30-month programme will specifically aim to develop, embed and exploit smart data driven technologies It will enable the business to increase quality, productivity and capacity. Aston University has begun a management Knowledge Transfer Partnership (mKTP) with nationwide accountants and business advisors Beever and Struthers to help drive the firm’s digital transformation. A management Knowledge Transfer Partnership is built around identifying strategic management-based initiatives to increase business effectiveness and improve management practices. As part of the mKTP, led by Aston University in collaboration with Professor Brian Nicholson and Dr Sung Hwan Chai (Alliance Manchester Business School), Dr George Moyenda Salijeni (Aston Business School) and the team will conduct a comprehensive evaluation of Beever and Struthers' existing data systems. Following the assessment, specific methodologies will be proposed to ensure alignment between the mKTP and the firm's ongoing data systems. The 30-month programme will aim to develop, embed and exploit smart data driven technologies within the audit function, enabling the business to increase the quality, productivity and capacity to deliver additional insight and value to clients. Dr George Salijeni, a lecturer in accounting at Aston Business School and an expert in data analytics tools used in external audits and knowledge base supervisor in the mKTP, said: “This mKTP offers an opportunity to share and utilise knowledge and technical exposure which academics at Aston University and Alliance Manchester Business School have gained and generated over the years through undertaking multi-disciplinary research and engagements with practitioners and audit regulators on data driven technologies which include artificial intelligence. Potentially, this project generates insights, workflows which could impact and transform the way audits are performed by leveraging data driven analytics tools and models.” Michael Tourville, partner at Beever and Struthers, said: “Given that the business has been around for up to 125 years it is quite traditional in its approach, but we are now keen to embrace the opportunities that a truly digital transformation could offer. Although we are a firm with a long history, we are also an entrepreneurial business and are keen to grasp opportunities when we see them. This mKTP is all about giving our clients more insight and helping us navigate data far better too. The main improvements for us will come from increased efficiency and insight, but we will also be able to further improve the quality of the service we offer.” Professor Andy Lymer, head of the Accounting Department at Aston University, said: “Digital approaches to accounting are increasingly at the heart of how the accounting industry works – and therefore increasingly at the heart of what we teach and research related to this industry and its practices. This extremely innovative project will enable us to work with the partners in this programme to go in depth into an organisation exploring how the use of the latest developments in the use of digital tools such as advanced data analytics can further enhance the processes of audit. The experience and knowledge gained in this work will be brought back into the classroom for our students to benefit from also.”

Ask an Expert: Can a Recession Boost Employee Job Satisfaction?

Will the United States tip into recession in 2023? The jury for many remains out, though there are enough clouds forming on the horizon to cause consternation for firms eyeing the next financial quarter. But while recessions invariably spell belt-tightening, are they always plain bad for business? Could there be some kind of silver lining to hard times? New research led by Goizueta Business School’s Emily Bianchi suggests there is in fact an upside to economic downturns: higher employee job satisfaction. Bianchi and colleagues from Oglethorpe and Hong Kong Polytechnic Universities have found that in times of increased financial uncertainty, people tend to think less about other opportunities or openings, and focus more on the jobs they actually have. This in turn makes us see our jobs and workplace more favorably, says Bianchi. “It might feel counter-intuitive because there’s reason to think that tumultuous times make the workplace and workplace relations more tense or challenging. But we wanted to explore whether the security of having a job in an economic slump might positively impact the way people think about their roles and employers,” Bianchi says. Our hunch was that fewer available jobs outside the organization may translate into greater satisfaction with the jobs we have in hand when there’s a recession. To test this possibility, Bianchi and co-authors ran three studies. The first looked at almost 50 years of data from the U.S. General Social Survey, a cross-sectional barometer of people’s attitudes and opinions, including their assessment of the economy and satisfaction with the work they do. Through analyses of respondents’ answers between 1974 and 2016, Bianchi et al. found compelling evidence to support their hypothesis: at both the national and state level, job satisfaction rose during recessions and fell off again when the economy did better. A second study analyzed data from the U.K. where recessions tend to hit at the same time as the United States, but can be more or less severe. Two surveys conducted by the University of Essex followed the same respondents between 1991 and 2013, allowing Bianchi et al. to measure how individual job satisfaction fluctuated with macro-economic changes. Limiting their analysis to those people who remained employed over the time period and controlling for things like age, gender and income, the researchers were able to isolate the impact of recession based on the way that a group of just over 8,500,000 employees felt about their jobs. They found the same pattern. “By looking at the same individuals over time, we’re able to eliminate any impact coming from changes in the composition of the workforce across economic cycles,” says Bianchi. The same pattern emerged: during bad economic times, people reported greater job satisfaction even within the same group. Unlocking the Upside of Downturns To dig deeper into the psychological mechanisms undergirding these patterns, Bianchi et al. ran an experiment. One group was shown “bad news” about the economy, while the other read a report on economic growth and “plentiful jobs.” Both groups were then asked to self-report on job satisfaction. Those who had read the news article on recession and unemployment reported greater contentment with their current jobs. Moreover, when reminded of recessions, they reported that alternative jobs became less salient, which in turn led to greater job satisfaction. In other words, their own jobs were “more satisfying.” One implication of these findings is that they challenge the notion that job satisfaction is exclusively dictated by what happens inside the organization. We tend to think of businesses as bubbles that are somehow impervious to the outside world. But these studies show broader societal events can affect us in surprising ways. A Silver Lining for Employers Recessions are rarely welcome news. And for employers, they can engender feelings of hopelessness, says Bianchi. The insights shared in her paper should provide some reassurance, nonetheless, that even when the chips are down, they might have one less thing to worry about. But there’s a caveat. Our findings suggest that there might actually be a bright side to recessions for employers; that greater job satisfaction during these difficult times might help people psychologically weather an otherwise challenging situation. “Of course, this does not mean that employers should take advantage of this surprising goodwill by asking more of their employees. Rather, while employers likely believe that there is little they can do to bolster job satisfaction during tough times, our research suggests that satisfaction-boosting efforts may be even more effective. Moreover, our findings suggest that employers should be more attuned to bolstering satisfaction when times are good and employees are particularly apt to be looking at other opportunities.” Interested in learning more about how a recession may impact the workplace?

But do they work? Researchers investigate effectiveness of lactation cookies on human milk production

Ana Palacios’ interview on “Eagle Eye View,” the official podcast of Georgia Southern University. Palacios discusses her research and how being a mom motivated her. Several esteemed nutrition researchers collaborated on “Effectiveness of Lactation Cookies on Human Milk Production Rates: A Randomized Controlled Trial,” which was recently published in The American Journal of Clinical Nutrition. David B. Allison, Ph.D., dean of the Indiana University School of Public Health-Bloomington (SPH-B), is among the researchers who conducted a one-month, randomized controlled trial of lactating parents of healthy babies in the same age range. Their findings revealed no evidence for an effect of consuming lactation cookies on human milk production. “Too often in the field of nutrition and food, strong beliefs—sometimes even well-reasoned conjectures based upon some scientific knowledge—are mistaken for demonstrated facts,” Allison said. “Conjecture is good, but knowing is better. We come to know about the effects of nutrition and dietary supplements through rigorous, randomized, controlled trials. Having conducted such a study on lactation cookies, we found no evidence for their effectiveness. “This does not mean that it is impossible for any lactation cookie to affect human milk production,” he continued. “This study does suggest that the cookies we studied—under the conditions we studied them—have no discernible effect. The burden of proof seems to now be on those who claim there is an effect.” The study followed 176 U.S. parents who were exclusively breastfeeding healthy two-month-old babies. One group of parents was provided a serving of commercially available lactation cookies to consume daily for a month; the other group of parents ate a serving of conventional cookies not designed to increase lactation, each day for a month. Through a weekly survey, parents reported the quantity of milk they produced after following a validated milk expression protocol using a hospital-grade breast pump, providing data that were analyzed by both the study authors and an independent statistician. These data demonstrated that the impact of consuming lactation cookies did not have a significant effect on how much milk was actually produced or perceived to be produced by the lactating parents. The authors assert that consumers should be cautious when considering the potential effect of this product, or any food and/or supplement that promotes health-promoting benefits without published, peer-reviewed scientific evidence to support its claims. As the researchers noted, these lactation cookies can contain substantial calories and sugars, which could affect postpartum weight loss efforts and related health issues. “Despite being a physician and nutrition scientist focused on early-life nutrition, I still remember how difficult breastfeeding was for me with both of my children,” said study lead author Ana M. Palacios, MD, Ph.D., assistant professor, Department of Health Policy and Community Health, Jiann-Ping Hsu College of Public Health at Georgia Southern University. “Our research highlights that lactation cookies, which include added sugars and saturated fat, may not have the said purported benefits of increasing milk production. Purchasing lactation cookies to increase milk production may pose an unnecessary cost and may have additional implications for parents, such as limiting post-pregnancy weight loss and reducing consumption of healthier foods. More research is needed to better understand what foods and nutrients can best help increase milk supply in diverse populations.” The full article, along with the list of contributing authors, is available by simply clicking the article below: Interested in learning more?

Why shoppers are paying more for a fake Amazon discount

By Halle Burton According to new research by Jinhong Xie, a Warrington College of Business professor at the University of Florida, more than a quarter of Amazon vacuum cleaners sold have increased their prices while pretending to offer discounts. Xie’s pricing phenomenon research is joined with Sungsik Park at the University of South Carolina and Man Xie at Arizona State University, publishing their analysis in the Marketing Science journal. A product’s price increase is paired with a previously unadvertised listing price, which encourages Amazon shoppers to receive a deceitful false discount. This faux discount drove higher sales despite the price increase, and shoppers end up paying 23% more on average. “When you see this list-price comparison, you naturally assume you are getting a discount. It’s not just that you didn’t get a discount. You actually paid a higher price than before the seller displayed the discount claim,” said Xie. Regulations currently prohibit deceptive pricing by requiring truthful price comparisons from the sellers, but a list price can still be misleading under these circumstances. Shoppers are misled by the timing of price comparisons where retailers advertise a price discount that actually only gives the impression of a deal. “Current regulations are all about the value of the list price, and they don’t say anything about misleading consumers by manipulating the timing of the list price’s introduction,” Xie said. Xie and her colleagues followed more than 1,700 vacuums on Amazon from 2016 to 2017 gathering observational data on their prices. “We found that by increasing the price by 23% on average, the seller achieves a 15% advantage in their sales rank among all products in the home and kitchen category,” Xie said. Xie encourages consumers to be aware, not make assumptions about discount claims and utilize multiple websites to compare prices. “We think that consumer organizations and regulators should evaluate this new marketing practice to determine whether and how to manage it.”
