Wealth index is a known predictor of body mass index (BMI). Many studies have reported a positive association between BMI and (SES). However, an in-depth investigation of the relationship between BMI and wealth index is lacking for urban slum settings.
To examine the association between BMI and wealth index in an urban setting in Nairobi, Kenya.
A total of 2003 adults between 40 and 60 years of age were included. BMI was derived from direct weight and height measurements. Wealth Index was computed using the standard principal component analysis of household amenities ownership. The relationship between BMI and wealth index was assessed using both linear and logistic regression models.
We found that BMI linearly increased across the five quintiles of wealth index in both men and women, after adjusting for potential confounding factors. The prevalence of obesity increased from 10% in the first wealth quintile to 26.2% in the fifth wealth quintile. The average BMI for women entered the overweight category at the second quintile wealth status, or the third quintile for the total population.
There exists a strong positive relationship between BMI and wealth index in slum settings. Health promotion interventions aimed at reducing obesity may consider using wealth index in priority setting.
财富指数是已知的身体质量指数（BMI）预测指标。许多研究报告了BMI与社会经济地位（SES）之间存在正相关关系。然而，对于城市贫民窟环境中BMI与财富指数之间的关系缺乏深入研究。
研究肯尼亚内罗毕城市环境中BMI与财富指数之间的关联。
共纳入2003名年龄在40至60岁之间的成年人。BMI通过直接测量体重和身高得出。财富指数采用家庭设施拥有情况的标准主成分分析法计算。使用线性和逻辑回归模型评估BMI与财富指数之间的关系。
在调整潜在混杂因素后，我们发现男性和女性的BMI在财富指数的五个五分位数中均呈线性增加。肥胖患病率从第一财富五分位数的10%增至第五财富五分位数的26.2%。女性的平均BMI在第二财富五分位数时进入超重类别，而总人口在第三财富五分位数时进入超重类别。
在贫民窟环境中，BMI与财富指数之间存在强烈的正相关关系。旨在减少肥胖的健康促进干预措施在确定优先事项时可考虑使用财富指数。
