Chantelle Hart, Ph.D. Associate Professor of Public Health Center for Obesity Research & Education Department of Public Health 3223 N. Broad Street Philadelphia, PA 19140MedicalResearch.com Interview with: Chantelle Hart, Ph.D. Associate Professor of Public Health Center for Obesity Research & Education Department of Public Health Philadelphia, PA 19140   MedicalResearch.com: What are the main findings of the study? Dr. Hart: Following one week of sleeping their typical amount, children 8-11 years old were asked to decrease and increase their time in bed by 1.5 hours/night for one week each in random order.  Compared to when children decreased their sleep, when they increased their sleep, they reported consuming 134 kcal/day fewer, had lower fasting levels of leptin, a hunger-regulating hormone that is also highly correlated with the amount of adipose tissue, and weighed approximately 0.5 lbs less.  Reported decreases in food intake were most pronounced later in the day.

MedicalResearch.com Interview with: Adam D M Briggs Academic Clinical Fellow British Heart Foundation Health Promotion Research Group, Nuffield Department of Population Health, University of Oxford, Oxford OX3 7LF, UK MedicalResearch.com: What are the main findings of the study? Answer: For the first time this study estimates the impact of a sugary drinks tax in the UK on obesity. We estimate the tax would reduce the number of adults with obesity by around 180,000 or just over 1% of all adults who are obese, and the number of adults who are either overweight or obese by 285,000. The greatest reductions are seen in young adults. We also estimate that the effects of the tax will be similar across all income groups. (more…)

MedicalResearch.com Interview with: Reina Haque, PhD, MPH Research scientist, Kaiser Permanente Department of Research & Evaluation MedicalResearch.com: What are the main findings of the study? Answer: The main study findings are that men who are overweight or obese when they are diagnosed with prostate cancer are more likely to die from the disease than men who are of healthy weight. In patients with more aggressive forms of prostate cancer, the researchers also found an even stronger correlation between obesity and mortality. The study was restricted to patients undergoing surgical treatment for prostate cancer, rather than other treatments such as radiation or hormone therapy. (more…)

MedicalResearch.com Interview Jennifer M. Poti PhD Candidate, Nutritional Epidemiology University of North Carolina at Chapel Hill MedicalResearch.com: What are the main findings of the study? Answer: Consumption of solid fat and added sugar (SoFAS) by children exceeds recommendations, but it was not known where kids obtain these “empty calories.” Analyzing data from over 22,000 US children, we found that children consumed about 1/3 of their calories as solid fat and added sugar for foods consumed from retail food stores (including grocery stores and supermarkets), schools, or fast food restaurants in 2009-2010, despite significant decreases from 1977 to 2010 at each location. These mean levels of empty calorie intake greatly exceeded recommended amounts not just for fast foods, but also for foods consumed from schools and from stores. For all survey years, foods consumed by children from schools were higher in solid fat content than foods obtained and consumed from retail food stores. (more…)

MedicalResearch.com Interview with: Sharon Curhan, MD, ScM Channing Division of Network Medicine Brigham and Women's Hospital Harvard Medical School Boston, MA 02115 MedicalResearch.com: What are the main findings of the study? Dr. Curhan: The main findings of our study are that higher body mass index and larger waist circumference are associated with an increased risk of acquired hearing loss, and higher level of physical activity is associated with a decreased risk of acquired hearing loss in women. Specifically, after adjusting for potential confounders, compared with women with BMI <25 kg/m2, the relative risk for hearing loss was 25% higher for women with BMI >40. Compared with women with waist circumference <71 cm, the relative risk for hearing loss was 27% higher for women with waist circumference >88 cm. Higher physical activity was inversely related to risk; compared with women in the lowest quintile of physical activity, women in the highest quintile of physical activity had a 17% lower risk of hearing loss. Walking, the most common form of physical activity among these women, was associated with a lower risk; women who walked 2 hours per week or more had a 15% lower risk of hearing loss than women who walked less than one hour per week. These findings provide evidence that maintaining healthy weight and staying physically active, potentially modifiable lifestyle factors, may help reduce the risk of hearing loss. (more…)

Answer: We found in this sample of relatively young, Finnish twins that there are clearly two different kinds of obesity. While most individuals with BMIs in the "obese" category will go on to develop the usual pathologies associated with obesity (namely diabetes, hypertensio, dyslipidemia), a fraction of the obese population seems to be spared. These "metabolically healthy obese" individuals displayed a number of features that were associated with a healthy metabolic profile despite considerable overweight: a capacity for hyperplasia of the adipose tissue (as opposed to just hypertrophy) seemed to be associated with maintained mitochondrial function, lack of inflammation and liver fat.

MedicalResearch.com Interview with Stephan  Zipfel  MD Professor of Medicine & Dean of Medical Education Head Department of Internal Medicine VI (Psychosomatic Medicine and Psychotherapy) University Medical Hospital Tuebingen President of the German College of Psychosomatic Medicine (DKPM) Co-Director of the centre for nutritional Medicine Tuebingen-Hohenheim 72076 Tuebingen / Germany MedicalResearch.com: What are the main findings of the study? Prof. Zipfel: Outpatient treatment of adults with anorexia nervosa by either enhanced cognitive-behaviour therapy, focal psychodynamic therapy, or optimised treatment as usual led to relevant weight gains and a decrease in general and eating disorder-specific psychopathology during the course of treatment. These positive effects continued beyond treatment until 12-month follow-up. Most patients completed treatment and the acceptance of both specific therapy approaches was high among both patients and therapists. (more…)

Dr. Mitchell S. Roslin, MD Lenox Hill Hospital Manhattan Minimally Invasive & Bariatric Surgery 186 E 76th Street, 1st Floor New York, NY 10021.MedicalResearch.com Interview with:

Dr. Mitchell S. Roslin, MD Lenox Hill Hospital Manhattan Minimally Invasive & Bariatric Surgery 186 E 76th Street, 1st Floor New York, NY 10021. MedicalResearch.com: What are the main findings of the study? Dr. Roslin: The cornerstone of medical management for weight loss and to prevent weight gain is to regulate glucose and insulin and prevent wide fluctuation.  Yet, Gastric bypass, widely considered the gold standard operation, accentuates these fluctuations.  The purpose of our study was to compare glucose tolerance of gastric bypass, sleeve gastrectomy and a modified version of duodenal switch that  preserves adequate intestine. We found that all operations improve insulin resistance, but that duodenal switch normalizes the curve, whereas gastric bypass causes wide spikes in insulin and glucose. (more…)

MedicalResearch.com Interview with: Christian K. Roberts Exercise and Metabolic Disease Research Laboratory, Translational Sciences Section, School of Nursing University of California, Los Angeles, CA MedicalResearch.com: How would you best summarize the main findings/results of this study? Answer: Our main finding was that HDL functioned better in its antioxidant role in subjects who participated in resistance exercise training (i.e. weight training) a minimum of 4 days a week, regardless of their weight—one group was lean (BMI <25) and the other overweight/obese (BMI >27) —than those who didn’t exercise (overweight, BMI >27, and untrained). In addition, HDL had similar effectiveness as an antioxidant in the overweight-trained group as in the as lean-trained group. Although indices of weight were associated with dysfunctional HDL, differences in fitness may be a better measure of who has healthier functioning HDL. (more…)

Nguyen Osteoporosis and Bone Biology Program Garvan Institute of Medical Research 384 Victoria Street, Darlinghurst NSW 2010 Australia MedicalResearch.com: What are the main findings of the study? Dr. Nguyen: We analyzed polymorphisms of the FTO (fat mass and obesity) gene in 934 elderly women of Caucasian background, and found that carriers of minor genotype (AA) of the SNP rs1121980 had a two-fold increase in the risk of hip fracture compared with carriers of major genotype (GG). Approximately 20% of women are carriers of the AA genotype. We estimate that about 17% of hip fracture cases could be attributed to the variation within the gene. (more…)

MedicalResearch.com Interview with: Ronald J. Iannotti, PhD Prevention Research Branch, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Maryland Trends in Physical Activity, Sedentary Behavior, Diet, and BMI Among US Adolescents, 2001–2009 MedicalResearch.com: What are the main findings of the study? Dr. Iannotti: Although average BMI percentile increased from 2001 to 2005 it did not increase from 2005 to 2009. This is consistent with some recent studies that suggest the increase in overweight and obesity may be leveling off. We suggest that we may be 'bending the curve'. During the same period, physical activity and consumption of fruits and vegetables increased while television watching and consumption of sweets and sweetened beverages decreased. We cannot say whether television watching was replaced with more time spent on computers but we did not find an increase in computer use from 2005 to 2009. (more…)

Dr. Taveras: The main findings of the study were that, overall, the body mass index of children in the intervention group dropped an average of 0.18, while it rose 0.21 in the control group. Children in the intervention group were sleeping about 45 minutes longer than children in the control group. Time spent watching television on weekends dropped about an hour per day in the intervention group, leading to a significant difference from the control group, which increased weekend TV viewing. Both groups had a small reduction in weekday TV viewing, with a greater decrease in the intervention group, as well. (more…)

MedicalResearch.com Interview with: Dr Søren Skøtt Andersen and Dr Michelle Schmiegelow Study done in collaboration between Roskilde University Hospital and Gentofte University Hospital in Denmark. MedicalResearch.com: What are the main findings of the study? Answer: The main finding of this study of young women was that a body mass index above or equal to 25 kg/m2 in metabolically healthy women was not associated with an increased risk of cardiovascular events (myocardial infarction or ischemic stroke) within 5 years of follow-up. A BMI >= 25 kg/m2 in women with any metabolic disorder was associated with a 4-fold significant increased risk of the end-point. As increasing BMI is strongly associated with risk of developing metabolic disorders, the key message of this study is to stress the importance of preventing the development of metabolic disorders in overweight/obese women during this possible "window of opportunity".

MedialResearch.com Interview with: Dr Catherine M. Phillips Health Research Board Centre for Diet and Health Research Room 4.033, Department of Epidemiology and Public Health Western Gateway Building, University College Cork, Cork, Ireland MedialResearch.com: What are the main findings of the study? Answer: Obesity is associated with increased risk of diabetes and heart disease leading to reduced life expectancy. However in recent years it has been recognized that not all obese individuals are at increased risk – these individuals have been described as being metabolically healthy obese (MHO) in that despite carrying excess weight they do not have the typical abnormal metabolic features associated with obesity such as hypertension, insulin resistance and alterations to their lipid profile. It is not clear what factors determine whether an obese person becomes metabolically healthy or unhealthy. In this study conducted at the Dept. of Epidemiology and Public Health at University College Cork, Ireland, we examined levels of a range of inflammatory markers in 2047 middle-aged Irish adults to investigate to what extent differences between metabolically healthy and unhealthy obese and non-obese male and female adults are explained by inflammatory status. Participants, who were between the ages of 50 and 69, completed lifestyle questionnaires, physical and clinical assessments, and underwent blood testing so their body mass index (BMI), metabolic profiles and inflammatory markers could be determined. We found that, regardless of a person’s BMI, having a favorable inflammatory profile was associated with being metabolically healthy. Specifically metabolically healthy individuals presented with lower levels of complement component 3, C reactive protein, tumour necrosis factor alpha, interleukin 6, plasminogen activator inhibitor-1, reduced white blood cell count and higher adiponectin levels compared to their metabolically unhealthy counterparts.

MedicalResearch.com  Interview with: Caroline Franck, MSc Dvisions of Cardiology and Clinical Epidemiology McGill University, Montreal, Quebec, Canada MedicalResearch.com: What are the main findings of the study? Answer: We found that, although subsidies are needed to protect farmers from production risks, the current allocation of payments encourages the sustained overproduction of a handful of grains and oilseeds. Overproduction contributes to making the end products cheaper, which are then processed into energy-dense and high-fat/sugar foods. Obesity should be treated as a systems problem, in which farm production plays an important role. (more…)
