The aim of this study was to test the relationship between anthropometry, ultrasonography, and dual-energy x-ray absorptiometry (DXA) for the assessment of body composition in clinical practice. ⋯ Both anthropometry and ultrasonography provide a reliable estimate of visceral adipose tissue in a non-obese population compared with DXA, whereas anthropometry prediction of subcutaneous adiposity is weak. Physicians should be aware of the limits of these techniques for the assessment of body composition.

Several studies have concluded a positive association between abdominal obesity, general obesity, and chronic diseases. However, the best anthropometric measures to predict the risk for chronic diseases should be clarified in each population. Therefore, the aim of this study was to compare the predictive power of A Body Shape Index (ABSI), body mass index (BMI), and waist-to-height ratio and Clinica Universidad de Navarra-Body Adiposity Estimator for metabolic syndrome (MetS) and cardiovascular disease (CVD) risks among Iranians in different age and sex categories. ⋯ Based on the AUC, we concluded that ABSI is a weak predictor for CVD risks and MetS. More studies are needed to determine the best predictor of CVD risk among the Iranian population.

The aim of this study was to explore, based on sex and age, knowledge regarding weight, height, and the perception of body shape in Spanish adults who attend dietary consultation. We also wanted to determine the participants' desired body shapes and what they considered their best health status. ⋯ Age and sex influence the perception of excess weight and body image. This could condition the demand of dietary treatment to improve the nutritional status.

Fish proteins are potential sources of natural medicines and food additives. There are many studies being performed to develop underutilized fish proteins. Therefore, the aim of this study was to determine how shark protein functions as a dietary supplement for bone health. ⋯ These results suggest that shark protein might suppress the bone loss caused by estrogen deficiency through the suppression of osteoclast formation.
