Adiposity is an important diabetes risk factor, and Asian Indians have elevated diabetes risk. This analysis assessed the relationship between behavioral and psychosocial factors and adiposity among Asian Indians to better understand factors driving elevated weight/waist circumference in this population.
This study used screening data (N=1285) from the D-CLIP study, a randomized controlled diabetes prevention trial in Chennai, India. Correlation tests and linear regression models were done to describe relationships among exposure variables (weight loss/exercise self-efficacy, fruit/vegetable intake, weekly exercise, past weight loss experience) and between these exposures and BMI or waist circumference.
Exercise and weight loss self-efficacy were positively correlated with average minutes per week exercising (R=0.26, p<0.0001) and fruit (R=0.07, p<0.05) and vegetable intake (R=0.12, p<0.0001). Weekly fruit consumption, past weight loss experience, and weight loss self-efficacy, along with sex, age, and marital status, explained 13.6% and 25.9% in the variation in BMI and waist circumference, respectively.
Low fruit consumption, unsuccessful past weight loss attempts, and low self-efficacy for weight loss are associated with higher BMI and waist circumference in this population. Understanding factors related to adiposity is important for preventing and treating weight gain.
肥胖是糖尿病的一个重要危险因素，亚洲印度人患糖尿病的风险较高。本分析评估了行为和心理社会因素与亚洲印度人肥胖之间的关系，以更好地了解导致该人群体重/腰围升高的因素。
本研究使用了D-CLIP研究的筛查数据（N = 1285），该研究是在印度金奈进行的一项随机对照糖尿病预防试验。进行了相关性测试和线性回归模型，以描述暴露变量（体重减轻/运动自我效能、水果/蔬菜摄入量、每周运动、过去的体重减轻经历）之间的关系，以及这些暴露与BMI或腰围之间的关系。
运动和体重减轻自我效能与每周平均运动分钟数（R = 0.26，p < 0.0001）、水果（R = 0.07，p < 0.05）和蔬菜摄入量（R = 0.12，p < 0.0001）呈正相关。每周水果摄入量、过去的体重减轻经历和体重减轻自我效能，连同性别、年龄和婚姻状况，分别解释了BMI和腰围变化的13.6%和25.9%。
水果摄入量低、过去减肥尝试未成功以及减肥自我效能低与该人群较高的BMI和腰围相关。了解与肥胖相关的因素对于预防和治疗体重增加很重要。
