目的：这项研究调查了5年的体重，超重和肥胖的趋势，以及他们与社会人口统计学变量的关联，在一个大的，多种族的澳大利亚成年人社区样本。设计：这项前瞻性人口研究使用了基线和5年的随访数据，从参与者在墨尔本合作队列研究（MCCS）。设置：人口研究在墨尔本，澳大利亚。主题：结果：该样本的平均5年体重变化男性为+1.58（标准差（SD）4.82）kg，女性为+2.42（SD 5.17）kg。年轻男性（35-44岁），特别是女性，体重增加比老年人多，体重增加（大于或等于5公斤）和超重的风险最高。主要体重增加的风险和人口统计学变量与体重变化之间的关联在种族之间没有很大差异。教育水平与体重结果之间存在复杂的关联，这些关联因性别和种族而异。多变量分析显示，在男性中，较高的初始体重与主要体重增加的可能性降低相关，而在女性中，那些最初超重或肥胖的女性比体重不足或健康体重的女性更有可能经历主要体重增加。在整个人口样本中，特别是在年轻女性和已经超重的女性中，都是值得警惕的。预防整个人口的体重增加和肥胖应该是一个紧迫的公共卫生优先事项。年轻到中年似乎是干预以防止未来体重增加的关键时期。
Objective: This study investigated 5-year trends in body weight, overweight and obesity and their association with sociodemographic variables in a large, multi-ethnic community sample of Australian adults.Design: This prospective population study used baseline and 5-year follow-up data from participants in the Melbourne Collaborative Cohort Study (MCCS).Setting: Population study in Melbourne, Australia.Subjects: In total, 12 125 men and 17 674 women aged 35-69 years at baseline.Results: Mean 5-year weight change in this sample was +1.58 (standard deviation (SD) 4.82) kg for men and +2.42 (SD 5.17) kg for women. Younger (35-44 years) men and, in particular, women gained more weight than older adults and were at highest risk of major weight gain (greater than or equal to 5 kg) and becoming overweight. Risk of major weight gain and associations between demographic variables and weight change did not vary greatly by ethnicity. Education level showed complex associations with weight outcomes that differed by sex and ethnicity. Multivariate analyses showed that, among men, higher initial body weight was associated with decreased likelihood of major weight gain, whereas among women, those initially overweight or obese were about 20% more likely to experience major weight gain than underweight or healthy weight women.Conclusions: Findings of widespread weight gain across this entire population sample, and particularly among younger women and women who were already overweight, are a cause for alarm. The prevention of weight gain and obesity across the entire population should be an urgent public health priority. Young-to-mid adulthood appears to be a critical time to intervene to prevent future weight gain.
