Dietary patterns and their association with general and central obesity among adult women were studied using a cross-sectional survey with multistage cluster sampling in urban and rural areas nationwide in Botswana. The participants in the study were adult women ( = 1019), 18-75 years old. The dietary patterns were identified using principal component analysis, and their associations with the body mass index and the weight-for-height ratio were examined. Factor analysis with varimax rotation was used to identify six dietary patterns (fast foods, refined carbohydrates, vegetables and fruits, fish and nuts, Botswana traditional foods, and organ and red meat dietary pattern). Overall, 24.5% of the women were overweight (BMI 25.0-29.99 kg/m) and 24.5% were obese (BMI > 30 kg/m). A waist-to-height ratio greater than 0.5 was observed for 42.2% of the women. With adjustment for age and education, individuals in the highest tertile of the Botswana traditional food pattern had a significantly higher risk of general obesity (RR = 1.40, 95% CI: 1.07-1.84) and central obesity (RR = 1.20, 95% CI: 0.97-1.48). With respect to the fish and nut pattern, a significant association was observed with central obesity only (RR = 1.43, 95% CI: 1.18-1.72). The Botswana traditional food pattern, characterised by a high carbohydrate intake, was found to be associated with a high risk of obesity in this study. However, more research is required to assess other factors contributing to obesity in women so that appropriate intervention programs can be put in place to help control this epidemic.
本研究采用多阶段整群抽样方法,在博茨瓦纳城乡进行横断面调查,研究了成年女性的饮食模式及其与全身肥胖和中心性肥胖的关系。研究对象为 18-75 岁的成年女性(n=1019)。采用主成分分析法确定饮食模式,并用因子分析检验其与体质指数和体重身高比的关系。采用方差极大旋转因子分析法确定了 6 种饮食模式(快餐、精制碳水化合物、蔬菜和水果、鱼和坚果、博茨瓦纳传统食物和器官及红色肉类饮食模式)。总的来说,24.5%的女性超重(BMI 25.0-29.99kg/m2),24.5%的女性肥胖(BMI>30kg/m2)。42.2%的女性腰高比大于 0.5。调整年龄和教育程度后,博茨瓦纳传统食物模式最高三分位个体全身肥胖(RR=1.40,95%CI:1.07-1.84)和中心性肥胖(RR=1.20,95%CI:0.97-1.48)的风险显著升高。对于鱼和坚果模式,仅与中心性肥胖存在显著相关性(RR=1.43,95%CI:1.18-1.72)。本研究发现,以高碳水化合物摄入为特征的博茨瓦纳传统食物模式与肥胖风险增加有关。然而,还需要进一步研究评估导致女性肥胖的其他因素,以便实施适当的干预措施来帮助控制这一流行。
