背景：肥胖在世界范围内呈上升趋势，发展中国家也不例外。人口统计学和社会经济因素都是导致肥胖的原因。坦桑尼亚很少进行调查，以确定肥胖的严重程度及其与这些风险因素的关系。本研究旨在确定2007年4月至2008年4月期间坦桑尼亚达累斯萨拉姆Kinondoni市18 - 65岁成年人的肥胖患病率及其相关危险因素。方法：采用随机抽样方法。对入选家庭的符合条件和同意的成员进行了访谈和人体测量。肥胖的定义采用身体质量指数（BMI）。结果：1249名受试者中，814名（65.2%）为女性。总肥胖率为19.2%（240/1249）。然而，肥胖在女性（24.7%）中比男性（9%）更为普遍，p < 0.001；在高社会经济地位的受访者中（29.2%）比中等社会经济地位（14.3%）和低社会经济地位（11.3%）的受访者中（p < 0.001），趋势值< 0.001；在低强度活动的受访者中（26.0%），趋势值< 0.001。结论：这项研究揭示了Kinondoni居民的肥胖患病率高于此前在该国其他地区的报道。在研究人群中，肥胖的独立预测因素是年龄增长、婚姻和同居、高社会经济地位、女性和较少的体育锻炼。
Background: Obesity is on the rise worldwide, not sparing developing countries. Both demographic and socioeconomic factors play parts in obesity causation. Few surveys have been conducted in Tanzania to determine the magnitude of obesity and its association with these risk factors. This study aimed at determining the prevalence of obesity and its associated risk factors among adults aged 18 - 65 years in Kinondoni municipality, Dar es Salaam, Tanzania from April 2007 to April 2008.Methods: Random sampling of households was performed. Interviews and anthropometric measurement were carried out to eligible and consenting members of the selected households. Obesity was defined using Body Mass Index (BMI).Results: Out of 1249 subjects recruited, 814 (65.2%) were females. The overall prevalence of obesity was 19.2% (240/1249). However, obesity was significantly more prevalent in women (24.7%) than men (9%), p < 0.001, among respondents with high socio-economic status (29.2%) as compared to those with medium (14.3%) and low socioeconomic status (11.3%), p value for trend < 0.001, and among respondents with light intensity activities (26.0%), p value for trend < 0.001.Conclusion: This study revealed a higher prevalence of obesity among Kinondoni residents than previously reported in other parts of the country. Independent predictors of obesity in the population studied were increasing age, marriage and cohabitation, high SES, female sex and less vigorous physical activities.
