目的：调查澳大利亚家庭的父母和后代的体重指数 (BMI) 与家庭特征（包括生活方式）之间的关联。设计和主题：对 219 个澳大利亚儿童家庭进行纵向调查，这些儿童的年龄在 9 至 18 岁之间，每三年进行一次调查。测量：社会经济状况、体重和身高、3 天记录的饮食或食物频率调查问卷、饮酒、吸烟习惯和身体素质结果：在 18 岁儿童中，在检查后代生活方式变量的模型中，身体健康对 BMI 的预测呈负相关（P = 0.012），而对儿子而言，BMI 与酒精摄入量的预测呈正相关（P = 0.046），而在女儿中，只有身体健康与身体健康呈显着负相关。在包括父母特征的模型中，18 岁儿子和女儿的 BMI 可以通过母亲和父亲的 BMI 显着预测，而与后代的酒精摄入量、吸烟、身体健康和父母的教育程度无关，而对于女儿来说，则可以通过父亲的酒精摄入量来预测。这些模型解释了女儿中 48% 的变异和儿子中 33% 的变异。在儿子和女儿中，在调查的 9 年内，超重或肥胖父亲（儿子 P = 0.033，女儿 P = 0.024）或母亲（儿子 P = 0.031，女儿 P = 0.037）的后代的 BMI 始终较高。 12岁、15岁和18岁的体质与女儿父亲肥胖和儿子母亲肥胖呈负相关。父亲肥胖与儿子和女儿 18 岁时肥胖风险增加四倍相关，如果母亲肥胖，女儿的风险独立增加八倍。出生体重与 18 岁青少年的超重或肥胖无关。儿子的酒精摄入量与父母一方的酒精摄入量显着相关，而对于女儿来说，仅与父亲的饮酒量显着相关。在女儿中，脂肪摄入量与父亲和母亲的脂肪摄入得分呈正相关。结论：父母超重或肥胖可能会导致儿童面临一系列不健康行为的风险。应优先考虑针对超重家庭，特别是社会经济地位较低的群体，推广健康的生活方式。
OBJECTIVE: To investigate associations between body mass index (BMI) and family characteristics, including lifestyle, in parents and offspring from Australian families.DESIGN AND SUBJECTS: Longitudinal survey of 219 families of Australian children who had been surveyed 3-yearly between the ages of 9 and 18y.MEASUREMENTS: Socio-economic status, weight and height, diet from 3 day records or food frequency questionnaires, alcohol consumption, smoking habits and physical fitness in offspring (bicycle ergometry in 18-y-olds).RESULTS: In 18-y-olds, in models examining offspring's lifestyle variables, BMI was predicted negatively by physical fitness (P = 0.012), and positively by alcohol intake (P = 0.046) in sons while, in daughters, only a negative association with physical fitness was significant. In models including parental characteristics, BMI in 18-y-old sons and daughters was significantly predicted by mothers' and fathers' BMI, independently of offsprings' alcohol intake, smoking, physical fitness and parents' education, and, in daughters, by fathers' alcohol intake. These models explained 48% of variance in daughters and 33% in sons. In both sons and daughters, BMI over the 9y of the survey was consistently higher in offspring with overweight or obese fathers (P = 0.033 for sons, P = 0.024 for daughters) or mothers (P = 0.031 for sons, P = 0.037 for daughters). Physical fitness at the ages of 12, 15 and 18y was negatively related to fathers' obesity in daughters and mothers' obesity in sons. Obesity in fathers was associated with a four-fold increase in risk of obesity at the age of 18y in both sons and daughters with an independent eightfold increase in risk for daughters if mothers were obese. Birthweight was unrelated to overweight or obesity in the 18-y-olds. Alcohol intake in sons related significantly to alcohol intake in either parent while, for daughters, there was a significant association only with fathers' alcohol consumption. In daughters, fat intake was positively associated with fat intake score in both fathers and mothers.CONCLUSION: Parental overweight or obesity may identify children at risk for a range of unhealthy behaviours. Promotion of a healthy lifestyle targeting overweight families, particularly in lower socio-economic groups, should be a priority.
