Abstract
n being. Growth and maturity produce changes in body composition and fat distribution which are affected by age, gender, nutritional status, diet, physical activity, hormones etc. Hence, the present study was initiated with the main objective of body composition as related to age, gender and nutritional status during pre- adolescence (9- 12 years), to assess body composition from skinfold thickness (SFT) and Body Stat 1500 Analyser (BSA), to assess nutritional status by anthropometry, to assess differences in body composition of boys and girls, to identify factors affecting body composition and assessing -. glucose levels of over weight subjects. The study was conducted on pre~adolescents of 9-12 years. A number of 150 subjects from each group viz., 9-1 0, 10- 1 1 and 1 1 - 12 years were (75 girls and 75 boys) studied fkom government and private schools of Hyderabad and Secunderabad Age and gender related changes in anthropometric measurements .- * z indicated that the height, weight, BMI and skinfold thickness in&as'ed with r- r- a 4 weight between boys and girls. The sum of four skinfold thickness was higher in girls than boys indicating higher fat content in girls. Nutritional status of subjects indicated that the majority of the subjects were nearer to NCHS standards indicating normal linear growth. According to BMI and weight for age classification, majority of the subjects of all the age groups were graded under severe chronic energy deficiency, normal and mild malnutrition group respectively. ody Stat 1500 Analyser (BSA) fat mass (% and kg) decreased with an increase in age whereas it was decreased when derived from skinfold thickness (SFT) in boys and girls. Both BSA and SFT fat free mass (% and kg) increased with an increase in age significantly in boys and girls. Mean fat free mass (% and kg) and water (% and kg) were significantly higher in boys than girls and the mean'fat (% and kg) was significantly higher in girls than boys in all the age groups. . Body composition as related to weight indicated that the mean lean body mass was significantly higher in the subjects who had maximum weight than the subjects with minimum weight in both boys and girls. BSA fat mass (% and kg) and fat free mass (% and kg) were significantly differed f?om SFT fat mass (% and kg) and SFT fat free mass (% and kg) in pre-adolescents indicating BSA was not suitable to assess body composition during pre-adolescenoe (9- 12 years).
