The overall aim of this study was to examine obesogenic factors in children from single and dual parent families. Data from the Longitudinal Study of Australian Children (LSAC) (8,717 children) were analyzed to examine the differences in children's activity levels, dietary intake and BMI according to parental status and determine the likelihood of childhood overweight and obesity in a single-parent household. There were higher rates of overweight and obesity in girls aged four to nine whose parents were single (OR 1:60). Children in single-parent households watched more television, ate more food high in fat and sugar and less fresh fruit and vegetables than children from dual-parent households. The findings suggested that an additive effect of dietary and activity variables may contribute to the higher rates of overweight and obesity in Australian children, and that girls from single-parent households may be particularly at risk.
本研究的总体目标是调查单亲家庭和双亲家庭儿童中的致肥胖因素。分析了来自澳大利亚儿童纵向研究（LSAC）（8717名儿童）的数据，以研究根据父母状况儿童活动水平、饮食摄入和体重指数的差异，并确定单亲家庭中儿童超重和肥胖的可能性。父母为单亲的4至9岁女孩超重和肥胖率更高（比值比1:60）。与双亲家庭的儿童相比，单亲家庭的儿童看电视更多，食用更多高脂肪和高糖食物，而新鲜水果和蔬菜摄入量更少。研究结果表明，饮食和活动变量的累加效应可能导致澳大利亚儿童更高的超重和肥胖率，且单亲家庭的女孩可能尤其面临风险。
