中国汉族人的皮下脂肪发育

目前尚未见中国各地汉族成人皮褶厚度的综合研究。于2009年至2013年在中国22个省测量了汉族成人26928例(男13221例,女13707例)的面颊皮褶、肱二头肌皮褶、肱三头肌皮褶、肩胛下皮褶、髂嵴上皮褶、小腿内侧皮褶的厚度,计算体脂肪率。运用u检验对城乡间皮褶厚度值进行比较,对6项皮褶厚度与纬度、经度、年龄进行相关分析。研究发现,总的说来,随纬度的减少（从北向南）、经度的增加（从西向东）、年龄的增加,汉族男性皮褶厚度增大,皮下脂肪增厚。随纬度的增加（从南向北）、年龄的增长,汉族女性皮褶厚度增大,皮下脂肪增厚,体脂率（PBF）增大。城市汉族男性皮褶厚度值均大于乡村汉族男性,城市女性肩胛下皮褶、小腿内侧皮褶厚度值接近于乡村女性,其余4项皮褶厚度值大于乡村女性（P<0.01）。城市男性PBF值大于乡村男性,城市女性PBF值小于乡村女性。城市男性、女性与乡村男性、女性均为肩胛下皮褶最厚、髂嵴上皮褶次之,以肱二头肌皮褶最为菲薄。

Skinfold thicknesses in a national probability sample of U.S. males and females aged 6 through 17 years

Cycles II and III of the Health Examination Survey included measurements of the skinfolds of over 14,000 individuals 6 through 17 years of age, statistically weighted to provide an accurate national probability sample. Analyses of the triceps and subscapular skinfolds of Negroes and whites are reported here, utilizing the median in preference to the mean. Females of either racial group have thicker skinfolds at all ages studied. Whites have greater median triceps thicknesses than Negroes of the same sex and age, but there are no differences between the two racial groups in the subscapular. Since, between all but one pair of adjacent ages in males, from 12 years on, the median triceps fold decreases, but the estimated cross-sectional are of fat increases, it is strongly recommended that reductions in triceps thickness not be automatically interpreted as meaning a loss of subcutaneous fat. Since greater skewness is found in the subscapular distributions in whites, but not in the triceps, it is suggested that racial differences in triceps thickness at these ages occurs from the operation of hereditary factors, while differences in the subscapular skinfold arise from environmental causes.     

Skinfold thickness, body measurements and age changes in Trio and Wajana Indians of Surinam

The nutritional status of Trio and Wajana is representative of a group living under primitive conditions in a favourable environment. In adults, skinfold thickness remains constant throughout life. The folds of females are thicker than those of males, the difference being most marked over the triceps and least at the subscapular. In children, skinfold thickness at the subscapular and suprailiac sites decreases from the 3–4 to the 5–6 age group, after which there is a rapid increase towards adult values. Age changes over the triceps are less marked, especially in males. Other measurements included arm and calf circumference, bone dimensions at the wrist, elbow, ankle and knee, weight, stature, leg and arm length and biacromial breadth. The two tribes differ significantly in several measurements. The Wajana are heavier but they tend to be shorter in stature, with shorter legs but broader elbows and wrists. Shoulder breadth and the circumference of the upper arm are greater in Wajana males but females do not show these differences. The Wajana have longer and broader heads, but the cephalic index is similar. The tribes also differ in hair texture.     

Seasonal variation and sex differences in the nutritional status in two local populations of wild Japanese macaques

Seasonal variations and sex differences in the nutritional status in two local populations of wild Japanese macaques (Macaca fuscata fuscata) were examined. It was hypothesized that the ecological condition and/or reproductive strategies of each sex determine the nutritional condition and its seasonal fluctuation in each sex. Morphometric measures such as body mass, thoracic and femoris circumferences, skinfold thickness in four places (triceps, biceps femoris, subscapular, and abdomen), and wet mass of mesenteric and omental fat were used for comparisons between sexes, seasons, and populations. Animals of the Shimane population were larger than those of the Boso population in most morphometric measures, abdominal skinfold, and mesenteric and omental fat mass, suggesting environmental and/or genetic differences in the two populations. Females of both populations had larger skinfolds and mesenteric and omental fat mass than males, indicating that females had more fat than males. Females showed seasonality in most measures, having two peaks of body mass, thoracic and femoris circumferences, abdominal skinfold, and mesenteric and omental fat masses in early spring and late fall. In contrast, males exhibited no clear seasonal variations for most measurements, except for biceps femoris and subscapular skinfolds, which showed peaks in summer. Most morphometric measurements significantly correlated to each other, particularly in females, but most skinfolds had no correlation with other measurements. These findings suggest that sexual dimorphism in body composition and its fluctuation may be affected by the different reproductive strategies of males and females.

Racial differences in subcutaneous fat patterns in children aged 7–15 years

In a stratified random sample of 278 children aged 7–15 years of an entire biracial community, skinfold measurements were taken on six standard body sites. We found that white children had generally thicker skinfolds than blacks for the same body weight, with a consistent exception: the subscapular skinfold was relatively thicker in blacks. It is suggested that this racial difference in distribution of fat may manifest a genetic adaptive trait developed under circumstances demanding both a caloric reserve and facilitation of convective heat loss in tropical climates.     

Birth Weight and Its Relationship to Size Attained and Relative Fat Distribution at 7 to 12 Years of Age

The relationship between birth weight and relative subcutaneous fat distribution at school age was considered in 131 boys and 106 girls 7 to 12 years of age. Relative fat distribution at school age was estimated with the ratio of the subscapular to triceps skinfolds (S/T) for the total sample, and with the ratio of the sum of two trunk (subscapular, midaxillary) to the sum of two extremity (triceps, medial calf) skinfolds (T/E) for subsamples of 102 boys and 63 girls. There were no sex differences in the S/T ratio (mm/mm), boys 0.62 ± 0.15, girls 0.63 ± 0.18; T/E ratio (mm/mm), boys 0.58 ± 0.13, girls 0.59 ± 0.16; and BMI (kg/m²), boys 17.1 ± 2.4, girls 16.9 ± 2.2. Second order partial correlations, controlling for age and the BMI or age and sum of skinfolds, between birth weight and the skinfold ratios are, respectively, ?0.22 and ?0.20 (p<0.01) for S/T and ?0.29 and ?032 (p<0.01) for T/E in girls, and ?0.18 and ?0.17 (p<0.05) for S/T and ?0.06 and ?0.6 for T/E in boys. Though low, the correlations suggest that as birth weight decreases proportionally more subcutaneous fat is accumulated on the trunk than on the extremities, more so in females than in males. Results of stepwise multiple regression analyses indicate that birth weight accounts for from 2% to 8% of the variance in relative subcutaneous fat distribution at school age.     

The Diabetes Alert study: growth, fatness, and fat patterning, adolescence through adulthood in Mexican Americans

Diabetes Alert is a multidisciplinary genetic and epidemiological study of Type II (non insulin-dependent) diabetes in Texas Mexican Americans. We report the anthropometry of 1,155 individuals 10 to 70 or more years with particular reference to overweight, fatness, and anatomical fat patterning in the sample. Children ages 10-18 of both sexes are growing at the 50th percentile of the reference data (U.S. Health and Nutrition Examination Survey-1) for height, Wt/Ht2, and triceps and subscapular skinfolds. Adults are well below median height but well above median Wt/Ht2 and skinfolds. Prevalence of obesity (Wt/Ht2 greater than or equal to 30) among adults is typically 30% or higher by age 30. Diabetics compared to age/sex-matched non diabetics have shorter sitting heights, have more upper body fat (subscapular skinfold), have less lower body fat (lateral calf skinfold), and were heavier at maximum weight and at age 18. The ratio of lower to upper body fat distribution decreases over the life cycle, being highest at adolescence and lowest at ages 40-50 in both sexes. Our results show a precipitous weight gain after maturity in the sample and an association of diabetes with differences in anatomical fat patterning. The age-related changes in fat patterning need to be explained in terms of their ecological and genetic influences.
