目的：研究社会经济、家庭和围产期因素与6- 12岁学童超重/肥胖之间的关系。方法：2003-2005年，对悉尼55所学校中符合条件的一年级学生（1765/2238，平均年龄6.7岁）和七年级学生（2353/3144，平均年龄12.7岁）进行调查。测量身高、体重和身体质量指数。超重或肥胖是根据国际肥胖工作组的分界点进行分类的。在父母调查表中寻求每个儿童的社会人口状况、家庭和围产期信息。结果：多因素调整后，父母教育程度较低与6岁儿童普遍超重和肥胖显著相关，比值比（OR）分别为1.52（95%可信区间（CI） 1.15-2.01）和2.16 （CI 1.34-4.13）。怀孕期间吸烟与6岁和12岁儿童肥胖的可能性较高相关，OR分别为1.90 （CI 1.05-3.46）和1.78 （CI 1.22-2.61）。人口归因风险估计表明，在12岁儿童中，14.9%和10.1%的肥胖流行病例可能分别归因于独生子女或体重过重的新生儿。结论：我们显示了社会经济、家庭和围产期因素与儿童体重状况之间的相互依存关系。提高对这些途径的理解可能有助于制定儿童肥胖预防策略。
Aim: To examine associations between socio-economic, familial and perinatal factors with overweight/obesity in 6- and 12-year-old schoolchildren.Methods: Eligible year-1 (1765/2238, mean age 6.7 years) and year-7 students (2353/3144, mean age, 12.7 years) from a random cluster sample of 55 Sydney schools were examined during 2003-2005. Height, weight and body mass index were measured. Overweight or obesity was classified using International Obesity Task Force cut points. Information about each child's socio-demographic status, familial and perinatal information was sought in parental questionnaires.Results: After multivariate adjustment, lower parental education was significantly associated with prevalent overweight and obesity in 6-year-old children, odds ratio (OR) 1.52 (95% confidence interval (CI) 1.15-2.01) and OR 2.16 (CI 1.34-4.13), respectively. Smoking during pregnancy was associated with a higher likelihood of being obese among both 6- and 12-year-old children, OR 1.90 (CI 1.05-3.46) and OR 1.78 (CI 1.22-2.61). Population attributable risk estimates indicate that 14.9% and 10.1% of prevalent cases of obesity in 12-year-old children may be attributable to being: an only child or a heavy newborn, respectively.Conclusions: We show interdependent relationships between socio-economic, familial and perinatal factors and childhood weight status. Improved understanding of these pathways may help in developing childhood obesity prevention strategies.
