CONTEXT Increased prevalence of obesity in childhood and adolescence, defined by the use of body mass index (BMI), has drawn attention towards direct measurement of body fat. OBJECTIVE To develop age-and sex-specific reference distribution of body fat in apparently healthy North-Indian children in the age group of 7-17 years and to assess agreement(More)
AIM Vitamin D deficiency (VDD) among adolescents is a major health problem in India. The aim of this study was to assess the efficacy of therapeutic/loading doses of vitamin D supplementation on serum 25-hydroxy vitamin D (25OHD) levels in vitamin D deficient adolescents. METHODS A total of 482 out of the 511 subjects recruited for the study were divided(More)
Obesity has been associated with increased bone mineral density (BMD). There is evidence of differential effect of regional fat on BMD. Hence, we undertook this study to evaluate the correlation between total body fat and its distribution with BMD in nonobese (mean body mass index: 25.0 ± 4.7 kg/m²) Indian adult volunteers. A total of 2347 participants(More)
OBJECTIVES To generate thyroid hormone reference norms using electro-chemiluminescence technique. DESIGN AND METHODS Cross sectional study on apparently normal 4349 Delhi adults (18-86 years). Predetermined exclusion criteria (goiter, hypoechogenicity or nodularity on ultrasound, elevated anti-thyroid peroxidase antibody, hypo or hyperthyroidism and(More)
OBJECTIVE There is controversy about the relation of thyroid functions and body mass index. The present study was aimed to assess the relationship between thyroid function and body mass index in Indian school children. DESIGN Population survey. PATIENTS Data were collected from 25 schools in 19 cities across five different geographical zones of India.(More)
OBJECTIVE To determine the age of pubertal onset and menarche in school-going girls, and to assess the impact of obesity on pubertal timing. DESIGN Cross-sectional. SETTING Seven schools across Delhi, India. PARTICIPANTS 2010 school girls, aged 6-17 years. METHODS Anthropometric measurement and pubertal staging was performed for all subjects.(More)
Dual-energy X-ray absorptiometry (DXA) assessment of body fat mass is precise and highly correlated with under water weighing. In view of ethnic differences, we undertook this study to prepare normative data for body fat mass in apparently healthy adult Indians and correlate it with body mass index (BMI). This cross-sectional population-based study included(More)
OBJECTIVE Primary - to determine the age of pubertal onset in Indian boys. Secondary - (a) to assess the impact of obesity on pubertal timing, (b) to assess the relationship between gonadotropins and puberty. DESIGN Cross-sectional. SETTING General community-seven schools across New Delhi. PARTICIPANTS Random sample of 1306 school boys, aged 6-17(More)
