The present study examined the relationship among body dissatisfaction, body fat and physical activity in British children from different ethnic groups.
Two hundred and seventy-six 11-14 year-old males and females (12.5 +0.8 years) took part in the study. Body dissatisfaction was assessed using a figure rating scale; percent body fat was determined by skinfold measures, and physical activity was assessed using a self-report measure.
Significant, positive relationships were evident between body dissatisfaction and body fat for the whole sample (r = -0.65, p < 0.01). Similar relationships were evident between body dissatisfaction and body fat when split by gender and ethnicity (both p < 0.01). No significant relationships were evident between body dissatisfaction and physical activity (all p > 0.05). ANCOVA controlling for body fat and physical activity revealed that as the covariate of physical activity increased, so did body dissatisfaction (F(1,269) = 13.36, p < 0.01). A significant interaction between fat and ethnicity was also evident (F2,269 = 4.49, p < 0.05). Girls had lower levels of physical activity (F(1,270) = 6.00, p < 0.01); greater body dissatisfaction (F(1,269) = 9.34, p <0.01), and greater fatness (F(1,275) = 37.51, p < 0.01) than boys.
The majority of children in this study were dissatisfied with their bodies and girls were more dissatisfied than boys. The main novel finding of this study was that the association between body dissatisfaction and body fatness differed across ethnic groups, with this association being greatest in Asian children (Indian, Pakistani and Bangladeshi in origin) in comparison to black and white children.
本研究调查了英国不同种族儿童的身体不满、体脂与身体活动之间的关系。
276名11至14岁的男性和女性(平均年龄12.5±0.8岁)参与了该研究。使用体型评定量表评估身体不满;通过皮褶测量法测定体脂百分比,并使用自我报告法评估身体活动。
整个样本中,身体不满与体脂之间存在显著的正相关关系(r = -0.65,p < 0.01)。按性别和种族划分时,身体不满与体脂之间也存在类似关系(均p < 0.01)。身体不满与身体活动之间未发现显著关系(所有p > 0.05)。控制体脂和身体活动的协方差分析显示,随着身体活动协变量的增加,身体不满也增加(F(1,269) = 13.36,p < 0.01)。脂肪与种族之间也存在显著交互作用(F(2,269) = 4.49,p < 0.05)。女孩的身体活动水平较低(F(1,270) = 6.00,p < 0.01);身体不满程度更高(F(,269) = 9.34,p <0.01),且比男孩更胖(F(1,275) = 37.51,p < 0.01)。
本研究中的大多数儿童对自己的身体不满意,女孩比男孩更不满意。本研究的主要新发现是,身体不满与体脂之间的关联在不同种族群体中有所不同,与黑人和白人儿童相比,这种关联在亚洲儿童(印度、巴基斯坦和孟加拉国裔)中最为明显。
