An understudied risk factor for overweight/obesity in our population is distorted body image perception where studies from the west have proved a clear association between the two. We therefore aimed to evaluate the same and document the prevalence of overweight/obesity among rehabilitated slum dwellers.
It was a cross-sectional study conducted during February 2015. The participants were recruited from among permanent residents of Tamil Nadu Slum Clearance Board residential apartment blocks. Systematic random sampling followed by cluster sampling was done. All consenting individuals above 18 years of age were included. Pregnant women, bed-ridden patients, and those who had an acute illness in the last 2 weeks were excluded. Data were collected using a semi-structured standardized pilot-tested questionnaire which included Stunkard's figure rating scale.
Number of families included was 170 comprising 315 individuals. Prevalence of overweight was 36.5% and prevalence of obesity was 12.4%. Prevalence of body image dissatisfaction was 68.3% (women 68.9% and men 67%), and prevalence of body image distortion was 59% (women 57.5% and men 62.1%). Distorted body image (adjusted odds ratio [aOR]; 95% confidence interval [95% CI]: 1.927; 1.057, 3.514) and underestimating body image size (aOR; 95% CI: 8.001; 4.223, 15.159) were highly significant predictors of obesity as estimated by logistic regression.
Although majority of population belonged to daily wage laborer workforce, prevalence of overweight is high. Distorted ideal and current body image perception is also significantly high and is a definite risk factor for obesity.
在我国人群中，一个研究较少的超重/肥胖风险因素是身体形象认知扭曲，西方的研究已证实两者之间存在明确关联。因此，我们旨在对此进行评估，并记录贫民窟居民康复后的超重/肥胖患病率。
这是一项于2015年2月进行的横断面研究。参与者从泰米尔纳德邦贫民窟清理委员会住宅公寓楼的常住居民中招募。采用系统随机抽样，随后进行整群抽样。纳入所有18岁以上的同意参与者。排除孕妇、卧床患者以及过去两周内患有急性疾病的人。使用经过预试验的半结构化标准化问卷收集数据，该问卷包括斯图卡德体型评定量表。
纳入的家庭有170个，共315人。超重患病率为36.5%，肥胖患病率为12.4%。身体形象不满意的患病率为68.3%（女性为68.9%，男性为67%），身体形象扭曲的患病率为59%（女性为57.5%，男性为62.1%）。通过逻辑回归估计，身体形象扭曲（调整优势比[aOR]；95%置信区间[95%CI]：1.927；1.057，3.514）和低估身体形象尺寸（aOR；95%CI：8.001；4.223，15.159）是肥胖的高度显著预测因素。
尽管大多数人口属于日薪劳动者群体，但超重患病率很高。理想和当前身体形象认知的扭曲也非常显著，并且是肥胖的一个明确风险因素。
