The body height and weight gain and sexual development are evident during puberty. The study samples were recruited from the Chin-shan Junior High School in Taipei County. The body height, weight and Tanner's sexual development stage of 338 students were measured twice in October 1994 and in April 1997 respectively. The results revealed: (1) there were no statistically significant differences in body height, weight and body mass index between boys and girls on the first examination; (2) bodys were higher and heavier (166.9 ± 7.2cm, 58.3 ± 11.7kg) than girl (157.1 ± 5.8cm, 52.3 ± 8.7kg) on the second examination, but no significant difference in body mass index between two sexes; (3) girl entered puberty ealier than boys, but then slow down sexual development during the period of junior high school; (4) as compared to normal weight students, the obese students on the first examination had a greater chance, 19.2 times for the
male and 11.1 times for the female, to be obese again on the second examination. The growth and development of boys and girls during puberty showed great diversity. From the results we recommend that health care and knowledge regarding sexual development should be provided earlier to students, particularly for girls. More attention and intervention strategy on adolescent obesity should be developed in order to reduce the risk of morbidity and mortality related to obesity in years later. |
