Secular changes in stature and body mass index for Chinese youth in sixteen major cities, 1950s–2005
Evidence shows a secular trend in physical growth in China in recent years. We analyze the secular trend of stature and body mass index (BMI) for the period 1950s-2005 to provide biological evidence for policy-makers to identify measures for improving Chinese children's health. Data come from the historical records in 1950s and the successive cycles of the Chinese National Survey on Student's Constitution and Health. Subjects were 7- to 18-year-o…
Age at spermarche and comparison of growth and performance of pre‐ and post‐spermarcheal Chinese boys
The prevalence of first ejaculation emission (spermarche) in Chinese Han boys in 1995 was considered. The subjects were 86,744 Han boys 9 through 18 years randomly selected from 28 provinces. Median spermarcheal ages (MSAs) were 14.4 and 14.6 years for urban and rural boys, respectively, and 14.3, 14.6, and 14.7 years for the boys of 1st, 2nd, and 3rd socioeconomic classes, respectively. Two environmental factors, ecological and socioeconomic, ha…
Age at menarche and comparison of the growth and performance of pre‐ and post‐menarcheal girls in China
Secular changes in the stature, weight, and age at maximum growth increments of urban Chinese girls from the 1950s to 1985
This study focuses on changes in the stature, weight, and age at maximum increments in Chinese urban girls 7–17 years of age between the 1950s and 1985. The data come from anthropometric surbeys in the 1950s, 1960s, 1970s, and 1985 in 17 Chinese cities. An overall increasing trend is apparent for stature and weight. The average increments are 1.91 cm and 0.57 kg per decade for 7 year olds, 3.43 cm per decade for 11 year olds, 2.11 kg per decade f…
Growth changes of Chinese Mongolian, Uygur, Korean, and Tibetan ethnic groups in the past forty years
Growth changes in stature and weight between 1950–60s and 1991 of four Chinese ethnic groups were surveyed: the Mongolian, Uygur, Korean, and Tibetan minorities. The subjects were school children and youths aged 7 through 17 years who lived in the urban areas of Huhehaote city, Wulumuqi city, and Lasa city, where the corresponding groups lived. An overall increase in body size was found in both boys and girls. Increments of stature and weight for…
