Prevalence of Overweight and Obesity among Rural Elderly Women in Liaoning Province and Its Risk Factors

目的分析辽宁省农村地区老年女性超重和肥胖的患病率及其相关危险因素。方法 2004年6月至2005年6月,采用分层整群随机抽样方法,对辽宁省农村地区3232名年龄在60岁以上的老年女性人群进行横断面研究。全部研究对象进行体格检查及生活方式等其他相关因素调查。超重及肥胖分别按WHO及中国标准定义。结果按WHO标准,超重及肥胖的患病率分别为17.7%和2.2%;而按中国标准,分别为23.7%和5.8%。通过多元Logistic回归分析:蒙古族、饮酒是超重与肥胖的危险因素;而年龄及吸烟则为保护性因素。结论辽宁省农村老年女性肥胖的患病率尽管较低,但其超重患病率仍处于较高水平。不健康的生活方式、年龄、民族与超重和肥胖相关。

Objective To investigate the prevalence of overweight and obesity among rural elderly women and its risk factors. Methods A cross-sectional cluster survey was conducted during 2004-2005 in Li- aoning province, China. A total of 3232 elderly women age ≥ 60 years were enrolled. Their baseline lifestyle and other factors were obtained. Overweight and obesity were separately defined according to both the World Health Organization （WHO） criteria and Chinese criteria. Results When the WHO criteria were applied, the prevalence of overweight and obesity was 17.7% and 2.2% , respectively. When the Chinese criteria were applied, the corresponding figures were 23.7% and 5.8% , respectively. Multivariate logistic regression analysis showed that Mongolian nationality and current drinking were the risk factors for overweight or obesity. Aging and current smoking status were negatively correlated with overweight and obesity. Conclusions Although the prevalence of obesity was low, the prevalence of overweight was relatively high among rural elderly women. Unhealthy lifestyle, aging, and ethnicity are risk factors of overweight and obesity in this population.
