The purpose of the present cross-sectional study was to examine the relationship and effect of monthly household income, birth order, and number of siblings on adult body dimensions, adiposity index, and body composition among adult Bengali females. One hundred seventy-one adult Bengali females, age 20.35 +/- 1.51 years (mean +/- SD; range: 18-21 years) from Kolkata (formerly Calcutta) were studied. Anthropometric measures (weight, height, waist circumference, hip circumference, and triceps, biceps, subscapular, suprailiac, and medial calf skinfold thicknesses) were taken from all participants using standard protocols. BMI and log10 of the sum of the five skinfold thicknesses were computed subsequently. Percentage of body fat was estimated from the triceps skinfold thickness following the equation of Durnin and Womersley (1974), and fat mass was then calculated. Results of the correlation analysis revealed that monthly household income had significant (p < 0.05) positive association with all anthropometric variables. Birth order and number of siblings showed significant (p < 0.05) inverse association. The correlation of monthly household income with anthropometric variables was much stronger for number of siblings and birth order. The results of the analysis of variance showed that monthly household income, birth order, and number of siblings (tertiles used to categorize all variables) had significant effects (p < 0.05) on anthropometric variables, indicating differences in adult body dimensions, the adiposity index, and body composition in relation to income, birth order, and number of siblings.

本横断面研究的目的是研究孟加拉成年女性的家庭月收入,出生顺序和兄弟姐妹数量对成年身体尺寸,肥胖指数和身体组成的关系和影响。研究了来自加尔各答 (以前的加尔各答) 的一百零一名孟加拉成年女性,年龄20.35/- 1.51岁 (平均/- SD; 范围: 18-21岁)。使用标准方案从所有参与者中进行人体测量 (体重,身高,腰围,臀围以及三头肌,二头肌,肩胛骨下,上肌和小腿内侧皮褶厚度)。随后计算了五个皮褶厚度之和的BMI和log10。根据Durnin和Womersley (1974) 的方程式从肱三头肌皮褶厚度估算身体脂肪的百分比,然后计算脂肪量。相关分析的结果表明,家庭月收入与所有人体测量变量具有显着的正相关 (p <0.05)。出生顺序和兄弟姐妹数量显示出显着 (p < 0.05) 的反向关联。对于兄弟姐妹的数量和出生顺序,家庭月收入与人体测量变量的相关性要强得多。方差分析的结果表明,家庭月收入,出生顺序和兄弟姐妹的数量 (用于对所有变量进行分类的三分位数) 对人体测量变量有显着影响 (p <0.05),表明成年人的身体尺寸,肥胖指数以及与收入有关的身体组成,出生顺序和兄弟姐妹的数量。
