撒哈拉以南非洲心血管疾病的增加部分归因于生活方式的改变，城市人群心血管疾病危险因素的患病率高于非城市人群。本研究的目的是确定超重和肥胖的患病率，并检查身体大小的性别和其他决定因素之间的贫民窟居民在内罗毕，Keny.MethodsAnalysis包括4,934名成年人随机选择的Korogocho和Viwandani贫民窟的内罗毕的看法。在访谈期间测量身高和体重;计算体重指数（BMI）。当前和理想的身体形象的看法，确定了使用18个剪影的身体尺寸，从非常薄，非常肥胖。我们采用多元Logistic回归分析，以确定预测低估超重和肥胖的responders.ResultsOverall，43.4%的女性和17.3%的男性在研究人群中的体重超重或肥胖。超过一半（53%）的超重或肥胖者低估了自己的体重; 34.6%的女性和16.9%的男性这样做。在所有的BMI类别中，超过三分之一的妇女和男子喜欢的身体尺寸分类为超重或obesity.ConclusionThis研究强调超重和肥胖的患病率和强烈的偏好较大的身体尺寸成人在内罗毕的贫民窟。有必要采取干预措施，教育居民了解与超重有关的健康风险，作为减少这些住区心血管疾病风险因素流行率战略的一部分。
IntroductionThe increase in cardiovascular diseases in sub-Saharan Africa has been attributed in part to the changes in lifestyle, and the prevalence of risk factors for cardiovascular disease is higher among urban populations than among nonurban populations. The objective of this study was to determine the prevalence of overweight and obesity and examine perceptions of body size differentiated by sex and other determinants among slum dwellers in Nairobi, Kenya.MethodsAnalysis included 4,934 adults randomly selected from the Korogocho and Viwandani slums of Nairobi. Height and weight were measured during interviews; body mass index (BMI) was calculated. Perceptions of current and ideal body image were determined by using 18 silhouette drawings of body sizes ranging from very thin to very obese. We used multivariate logistic regression analysis to determine predictors of underestimation of body weight among overweight and obese respondents.ResultsOverall, 43.4% of women and 17.3% of men in the study population were overweight or obese. More than half (53%) of those who were overweight or obese underestimated their weight; 34.6% of women and 16.9% of men did so. In all BMI categories, more than one-third of women and men preferred body sizes classified as overweight or obese.ConclusionThis study highlights the prevalence of overweight and obesity and the strong preference for larger body size among adults in the slums of Nairobi. Interventions to educate residents on the health risks associated with excess body weight are necessary as a part of strategies to reduce the prevalence of risk factors for cardiovascular disease in these settlements.
