OBJECTIVE Insulin resistance (IR) and associated metabolic abnormalities are increasingly being reported in the adolescent population. Cut-off value of homeostasis model of assessment IR (HOMA-IR) as an indicator of metabolic syndrome (MS) in adolescents has not been established. This study aimed to investigate IR by HOMA-IR in urban Indian adolescents and to establish cut-off values of HOMA-IR...

To the Editor: In South Africa, a substantial segment of the population is overweight.1 In 2000, non-communicable diseases (NCDs) accounted for 37% of deaths among adults2 and this figure is rising alongside expanding waistlines. Overweight children are twice as likely to have elevated blood pressure, 13 times more likely to have elevated insulin levels, and 7 times more likely to have higher t...

OBJECTIVE Few studies have examined variations in overweight and obesity by geographic location in youth. The purpose of this study was to investigate the association between urban/rural geographic status and being overweight or obese among Canadian adolescents. METHODS The study involved an analysis of a representative sample of 4851 Canadian adolescents in grades 6 to 10 from the 2001-02 He...

BACKGROUND To develop a screening algorithm to detect hepatic steatosis in overweight and obese adolescents. METHODS We performed a cross sectional study of 129 overweight adolescents 13-18 yrs. The primary outcome, hepatic steatosis was defined as an intracellular triglyceride content > 5.5 mg/g and quantified using (1)H-magenetic resonance spectroscopy. Primary predictor variables included,...

BACKGROUND The prevalence of obesity and overweight in children and adolescents is increasing world-wide. Obesity in children and adolescents is a major risk factor for diabetes, heart diseases, hypertension, and cancer in adulthood. AIM The aim of the study was to compare the nutritional status and food-stuffs among high-school girls in Arak, Iran, in matter of body mass index (BMI) and asso...

Overweight appears when persistent positive energy imbalances occur for long periods of time. Knowledge of dietary risk factors during childhood and adolescence is needed in order to design preventive measures against the increase in the prevalence of obesity and its consequences but is, however, largely missing. Longitudinal studies in children have not found clear causal associations between ...

Objective. The aim of this study was to find out the prevalence of overweight and obesity among adolescents in seven Arab countries using similar reference standard. Methods. A school-based cross-sectional study was carried out in seven cities in Arab countries, namely, Algeria, Jordan, Kuwait, Libya, Palestine, Syria, and United Arab Emirates. A multistage stratified random sampling technique ...

background: the aim was to investigate the relationships among lean mass (lm), fat mass (fm), and bone mineral density (bmd) in women stratified by body mass index (bmi) (bmi – normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with bmd. methods: this was a cross-sectional study in 471 healthy caucasian women, aged 18-67 years. bmd, lm, ...
