The aim of this study was to validate self-reported anthropometric measurements and body mass index (BMI) classifications in a young adult population. ⋯ Good agreement was detected between self-reported and direct anthropometric measurements. The criticism of self-reported anthropometric measurements is unwarranted. The findings provide support for using self-reported height and weight data for research in Australian young adults when direct measurements are not feasible.

The aim of this study was to observe the variation of iodine concentration in breast milk and urine in exclusively breastfeeding women and their infants during the first 24 wk after childbirth. ⋯ The iodine nutrition in lactating women and infants were adequate during the first 24 wk after childbirth. M-BMIC declined from week 1 to week 8 postpartum. Both I-UIC and M-UIC dropped from week 1 to week 4 postpartum. Further studies are needed to explore a more definitive BMIC and UIC range for an optimal iodine status in lactating women and breastfed infants.

Review Meta Analysis
Lowering breakfast glycemic index and glycemic load attenuates postprandial glycemic response: A systematically searched meta-analysis of randomized controlled trials.
Low glycemic index (GI) diets are recommended to reduce the risk for chronic diseases by managing postprandial elevations in blood glucose and insulin. However, to our knowledge, a systematic review of randomized controlled trials (RCTs) to investigate this relationship and interpret its clinical relevance has yet to be performed. This review aims to assess the effect of low versus high GI breakfast meals on postprandial glycemic and insulinemic responses in adults. ⋯ Low GI breakfasts significantly reduced postprandial blood glucose concentrations at all time points: 60 min (WMD: -1.32 mmol/L; 95% CIs, -1.64 to -0.99), 90 min (WMD: -0.74 mmol/L; 95% CI, -0.92 to -0.56), and 120 min (WMD: -0.44 mmol/L; 95% CI, -0.63 to -0.26). Further analyses not only indicated similar trends following the stratification of studies according to the glycemic load, but also showed a more pronounced decline in glycemic response among individuals with metabolic impairments. These results highlight the benefits of lowering breakfast meal GI to provide clinically relevant reductions in acute glucose response.

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver morbidity. This condition often is accompanied by obesity, diabetes, and metabolic syndrome (MetS). The aim of this study was to evaluate the connection between lifestyle factors and NAFLD in individuals with MetS. ⋯ Physical activity, adherence to the Mediterranean diet, and consumption of legumes were inversely associated with a non-invasive marker of NAFLD in individuals with MetS. This data can be useful in implementing precision strategies aimed at the prevention, monitoring, and management of NAFLD.

In 2013, the American Medical Association recognized obesity as a disease, of growing scientific, social, and political interest. In 2016 in the United States, prevalence rates of preobesity and obesity exceeded 60%. In Italy, these rates exceeded 40%. ⋯ Obesity has all the criteria to be recognized as a disease. Proper clinical management will lead to cost and complications savings, such as in diabetes. The aim of this review was to discuss in detail the criteria for defining primary obesity as a disease in a step-by-step manner.
