Fatty Pancreas and Cardiometabolic Risk: Response of Ectopic Fat to Lifestyle and Surgical Interventions.

Ectopic fat accumulation in non-adipose organs, such as the pancreas and liver, is associated with an increased risk of cardiometabolic disease. While clinical trials have focused on interventions to decrease body weight and liver fat, ameliorating pancreatic fat can be crucial but successful intervention strategies are not yet defined. We identified twenty-two published studies which quantified pancreatic fat during dietary, physical activity, and/or bariatric surgery interventions targeted at body weight and adipose mass loss alongside their subsequent effect on metabolic outcomes. Thirteen studies reported a significant decrease in body weight, utilising weight-loss diets (n = 2), very low-energy diets (VLED) (n = 2), isocaloric diets (n = 1), a combination of diet and physical activity (n = 2), and bariatric surgery (n = 5) including a comparison with VLED (n = 1). Surgical intervention achieved the largest decrease in pancreatic fat (range: -18.2% to -67.2%) vs. a combination of weight-loss diets, isocaloric diets, and/or VLED (range: -10.2% to -42.3%) vs. diet and physical activity combined (range: -0.6% to -3.9%), with a concurrent decrease in metabolic outcomes. While surgical intervention purportedly is the most effective strategy to decrease pancreas fat content and improve cardiometabolic health, the procedure is invasive and may not be accessible to most individuals. Given that dietary intervention is the cornerstone for the prevention of adverse metabolic health, the alternative approaches appear to be the use of weight-loss diets or VLED meal replacements, which are shown to decrease pancreatic fat and associated cardiometabolic risk.

High body fat percentage and low consumption of dairy products were associated with vitamin D inadequacy among older women in Malaysia.

BACKGROUND: Serum vitamin D insufficiency is a public health issue, especially among older women. Sun exposure is fundamental in the production of vitamin D, but older women have less optimal sun exposure. Therefore, factors such as body composition and diet become more essential in sustaining sufficient serum levels of vitamin D. The objective of the current study is to determine factors contributing towards serum vitamin D insufficiency among 214 older women. METHODS: The respondents had their body weight, height, waist circumference and body fat percentage measured, as well as interviewed for their socio-demographic characteristics, sun exposure and dietary intake. Fasting blood samples were obtained from the respondents to measure their serum 25-hydroxyvitamin D [25(OH)D] concentration. RESULTS: There were 82.7% (95% CI: 77.6%, 87.8%) of the respondents that had serum vitamin D insufficiency (< 50 nmol/L) with an average of 37.4 ± 14.3nmol/L. In stepwise multiple linear regression, high percentage of body fat (ß = -0.211, p <0.01) and low consumption of milk and dairy products (ß = 0.135, p <0.05) were the main contributors towards insufficient serum vitamin D levels, but not socio-demographic characteristics, other anthropometric indices, sun exposure and diet quality. CONCLUSION: Older women with high body fat percentage and low dairy product consumption were more likely to have serum vitamin D insufficiency. Older women should ensure their body fat percentage is within a healthy range and consume more milk and dairy products in preventing serum vitamin D insufficiency.

Comparison of Paternal and Maternal Feeding Practices and Parenting Styles between Healthy Weight and Overweight or Obese Primary School Children

@#Introduction: Parents play significant roles in developing the behaviour of their children towards food. However, mothers usually represent the parents of the children in previous studies, while fathers were left out and their contribution remained unknown. This study compared paternal and maternal feeding practices and parenting styles between overweight or obese (OW/OB) and normal weight (NW) primary school children. Methods: There were 419 children aged 10 to 11 from four randomly selected national primary schools being screened for their body weight and height. There were 105 children identified as OW/OB and matched with 105 NW children based on sex, age and ethnicity, whose both their parents were then recruited as study subjects. Parents reported their personal body weight and height, and completed a questionnaire on parenting styles and feeding practices. Results: There were 34.9% of children overweight and obese, and more than half of their fathers (66.5%) and mothers (52.5%) were overweight and obese. Both fathers and mothers of the OW/OB children perceived their children to be slightly heavier, but a majority of them perceived their children’s body weight status less accurately and applied less pressure to eat. Fathers of the OW/OB children were more in the obese category, performed indulgent parenting style, perceived less feeding responsibility and applied less monitoring on their children, but not mothers. Conclusion: There were distinct differences in paternal and maternal feeding practices and parenting styles between OW/OB and NW children. Researchers should encourage fathers to involve in childhood obesity research instead of focusing on mothers
