目的：这项横断面研究旨在确定超重恢复力女性的社会人口学和行为特征，即处于健康体重范围内的女性，尽管生活在社会经济条件较差的社区，这会增加她们肥胖的风险。这项研究还旨在测试个人、社会和环境因素与肥胖之间关系的综合理论模型。参与者：来自澳大利亚维多利亚州80个城市和农村社区的总共3235名年龄在18-45岁之间的女性，参与了尽管不平等的研究，但她们对饮食和活动的韧性。衡量标准：女性报告身高、体重、社会人口统计特征、休闲体育活动、饮食行为，以及一系列理论得出的认知、社会和社区环境特征，假设这些特征会影响肥胖风险。使用结构方程模型对预测体重指数(BMI)的理论模型进行了检验。结果：被归类为肥胖“弹性”的女性往往更年轻，出生在海外，受教育程度更高，未婚，家庭收入较高或未披露。与超重/肥胖女性相比，她们从事更多的休闲体育活动，吃更少的快餐和软饮料。社区特征、社会特征和认知特征都有助于解释BMI在假设方向上的差异。结论：这些结果表明，尽管生活在社会经济条件较差的社区会增加女性患肥胖症的风险，但女性对肥胖表现出几个特征。研究结果确认了横断面研究设计，提出了旨在调查肥胖风险的理论框架，通过提供证据支持对邻里肥胖的直接和间接影响以及社会、认知和行为特征的综合模型。《国际肥胖杂志》(2012年)36855865；DOI：10.1038/ijo.2011.183；2011年9月20日在线发表
Objective: This cross-sectional study aimed to identify sociodemographic and behavioural characteristics of 'overweight-resilient' women, that is, women who were in a healthy body weight range, despite living in socioeconomically disadvantaged neighbourhoods that place them at increased risk of obesity. The study also aimed to test a comprehensive theoretically derived model of the associations between intrapersonal, social and environmental factors and obesity among this target group.Participants: A total of 3235 women aged 18-45 years from 80 urban and rural neighbourhoods throughout Victoria, Australia, participated in the Resilience for Eating and Activity Despite Inequality study.Measurements: Women reported height, weight, sociodemographic characteristics, leisure-time physical activity, dietary behaviours and a range of theoretically derived cognitive, social and neighbourhood environmental characteristics hypothesized to influence obesity risk. A theoretical model predicting body mass index (BMI) was tested using structural equation models.Results: Women classified as 'resilient' to obesity tended to be younger, born overseas, more highly educated, unmarried and to have higher or undisclosed household incomes. They engaged in more leisure-time physical activity and consumed less fast foods and soft drinks than overweight/obese women. Neighbourhood characteristics, social characteristics and cognitive characteristics all contributed to explaining variation in BMI in the hypothesized directions.Conclusions: These results demonstrate several characteristics of women appearing 'resilient' to obesity, despite their increased risk conferred by residing in socioeconomically disadvantaged neighbourhoods. Acknowledging the cross-sectional study design, the results advance theoretical frameworks aimed at investigating obesity risk by providing evidence in support of a comprehensive model of direct and indirect effects on obesity of neighbourhood, as well as social, cognitive and behavioural characteristics.
