Obesity is associated with alterations in the vitamin D endocrine system. Lower levels of serum 25-hydroxyvitamin D (25-OHD) in morbidly obese individuals may be secondary to an alteration in tissue distribution resulting from an increase in adipose mass. Therefore, morbidly obese individuals are expected to need higher doses of vitamin D supplementation than the general population. However, it...

This cross-sectional study aimed to determine ethnic and environmental influences on the relationship between BMI and percentage body fat, using a sample of 144 Japanese and 140 Australian-Caucasian men living in Australia, and eighty-eight Japanese men living in Japan. Body composition was assessed by anthropometry using standard international methods (International Society for the Advancement...

OBJECTIVE To evaluate the relationship between the stages of somatic maturation and body composition in eutrophic female adolescents with or without excessive body fat. METHODS Cross-sectional study of 118 female adolescents, from 14 to 19 years-old, in Viçosa, Minas Gerais, Southeast Brazil. The adolescents were divided in two groups: Group 1 (G1), eutrophic with adequate body fat percentage...

Background and Objectives: Sarcopenia is explained as age-related reduction in muscle mass and performance. Some of the most important risk factors for sarcopenia include age, malnutrition, and sedentary life style. The aim of this study was to investigate the association of food intake and physical activity with body composition, muscle strength and muscle function in post-menopausal women. ...

[Purpose] The aim of this study was to determine the effects of high-frequency current therapy on the abdominal obesity levels of young women. [Subjects] Twenty-two women with abdominal obesity were randomly allocated to either an experimental group (n 1 = 10) or a control group (n 2 = 12). [Methods] The experimental group subjects received high-frequency current therapy for the abdominal regio...

OBJECTIVE To assess whether the indicators of weight status body mass index and waist-to-height ratio are similar to body fat percentage to identify obese children and adolescents with unfavorable lipid profile. METHODS This was a cross-sectional study involving 840 children and adolescents (6-18 years). The same individuals were classified as non-obese (<P95) or obese (≥P95) according to bod...

BACKGROUND Female fecundity is regulated by nutritional status. Although widely cited, this hypothesis is not strongly supported by empirical data from non-obese, healthy women of reproductive age. METHODS Healthy, reproductive aged women (n = 141) from Southern Poland collected daily morning saliva samples for one complete menstrual cycle. Levels of 17-beta-estradiol were analyzed by radioim...

To evaluate the extent to which fat mass contributes to serum osteopontin (OPN) concentration, we investigated whether serum OPN levels are decreased by exercise-induced fat mass loss and whether they are associated with body fat percentage in obese humans. Twenty‑three female college students were recruited to participate in an 8‑week body weight control program. Body composition [body weight,...

OBJECTIVE Determining the correlation between equations for estimating body fat percentage (BFP) based on Slaughter's anthropometric equation, which deals with skinfold measurement, and Deurenberg's equations for predicting total percentage body fat (%BF) which use body mass index (BMI) results. METHODS This study used data concerning 1,341 children and adolescents aged seven to 15 years-old ...
