Heritability of serum dehydroepiandrosterone sulphate levels and pubertal development in 6∼18-year-old girls
Serum DHEAS concentrations of pubertal girls are mainly influenced by genetic factors, especially during the period of adrenarche. The results stress the importance of research into the genetic regulation of the endocrine regulators involved in adrenarche and related metabolic disorders in girls
Sexual coercion and health-risk behaviors among urban Chinese high school students
OBJECTIVE: To determine the association between health-risk behaviors and a history of sexual coercion among urban Chinese high school students. DESIGN: A cross-sectional study was performed among 109,754 high school students who participated in the 2005 Chinese Youth Risk Behavior Survey. Data were analyzed for 5,215 students who had experienced sexual intercourse (1,483 girls, 3,732 boys). Multivariate logistic regression was used to determine …
Secular growth changes in stature and weight for Chinese Mongolian youth, 1964–2005
The positive growth changes of Chinese Mongolian people are closely related to urbanization, socio-economic progress and living improvements
Secular growth changes in body height and weight in children and adolescents in Shandong, China between 1939 and 2000
Positive secular trends occurred in 7-18-year-old children and adolescents in Shandong Province, China during 1939-2000, which may reflect the secular changes in socio-economic status
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…
Onset of the release of spermatozoa (spermarche) in Chinese male youth
Data on the prevalence of the first ejaculating emission for 83,902 Chinese boys 9 through 18 years were collected using interviews. Median spermarcheal ages (MSAs) were calculated by using the status quo data and probit analysis. Subjects consisted of 61,812 Han boys from urban and rural areas in 29 provinces, and 22,090 minority boys from 17 minority ethnic groups. Median spermarcheal ages were 14.24 years for urban Han boys and 14.85 years for…
Age at menarche and comparison of the growth and performance of pre- and post-menarcheal girls in China
The median menarcheal ages (MMAs) of Chinese girls in 1991 were calculated by using the status quo method and probit analysis in 64,322 schoolgirls 8-18 years of age. The sample was randomly selected from 29 provinces of China. The MMAs were 13.01 ± 1.19 and 13.64 ± 1.24 years for urban and rural girls, respectively. These estimates were 0.16 and 0.20 years lower than that of Chinese urban and rural girls in 1985, respectively. The associations b…
Changes in somatotype during growth in Chinese youth 7–18 years of age
Heath-Carter anthropometric somatotypes were calculated for 7,710 Chinese youths (4,434 boys and 3,276 girls), 7-18 years of age in the context of sex and age differences in distributions during adolescence. Age-specific trends are characterized by a consistent increase in endomorphy in girls and generally stable mesomorphy in boys. Somatotypes are consistently dominant in mesomorphy in boys and in endomorphy in girls across all ages. Somatotype …
Different Growth Status of Youths Aged 18 from 27 Chinese Minority Nations
This study focused on studying the morphological similarities of 27 Chinese minority nations' youths aged 18 by using PCA-Q mode cluster analysis. Six measurements of body size, two indices of body shape and four indices of growth tempo (which were estimated from cross-sectional data of 69, 389 subjects aged 7 through 18 by using proportional interpolation method) were used as variables. The values of these variables were normalized into principa…
Cluster analysis on body size of children aged 7 of 27 Chinese minority nations
By using PCA-Q mode cluster analysis, the morphological differences and similarities among Chinese minority nations were studied. The data was drawn from 2,473 boys and 2,356 girls aged 7 who came from 27 Chinese minority nations and participated in the "National Survey on Students Constitution and Health". Their body sizes were reflected by six physical measures. At first, the values of these measures were normalized into principal component sco…
The geographic clustering of body size of Chinese children aged 7 years
We studied the morphological differences and similarities among Chinese Han children aged 7 years by using PCA-Q mode cluster analysis. The data were drawn from 17,119 boys and 17,084 girls who came from 28 provinces and participated in the 1985 National Survey on Students Constitution and Health. The children were divided into urban and rural subgroups in each province. First, the values of six measures of body size (stature, sitting height, bod…
