Prevalence and Predictors of Overweight and Obesity among Military Personnel with Low Socio-Economic Status in Kuala Lumpur

Background: It is a major public health concern when 52% of adults worldwide were overweight and obese. Military institutions worldwide were included, which led to negative impacts on the overall combat readiness due to the obesity-associated-diseases. This study determined the prevalence and predictors of overweight and obesity among the low socioeconomic status (SES) army personnel in Kuala Lumpur. Methods: A cross-sectional study involving 772 low SES army personnel in Kuala Lumpur was conducted. Online questionnaires were distributed while anthropometric measurements’ data were obtained from Military Lifetime Health Record (MLHR) system with BMI of > 25kg/m 2 as the outcome. Data analysed using SPSS version 23.0 (descriptive and inferential statistics). Results: The median age of the respondents was 30 (IQR=7) years. The prevalence of overweight and obese army personnel was 41.1% (95%CI:37.6-44.6). The predictors found were being married (AOR:2.026,95%CI:1.318-3.113), secondary education (AOR:2.545,95%CI:1.245-5.203), Lance Corporal (AOR:1.994,95%CI:1.061-3.748), Corporal (AOR:2.814,95%CI:1.578-5.020), Sergeant (AOR:4.174,95%CI:2.076-8.390), past injury (AOR:1.879,95%CI: 1.191-2.965), history of obese sibling (AOR:1.737,95%CI:1.013-2.973), history of obese parent (AOR:3.344,95%CI:1.965-5.688), history of obese grandparent (AOR:11.321,95%CI:2.207-58.072), poor knowledge on dietary intake (AOR:1.524,95%CI:1.077-2.157), less than 2 litres daily plain water intake (AOR:1.606,95%CI:1.166-2.210). Conclusions: Knowledge on dietary intake and plain water intake are the two modifiable predictors for overweight and obesity found in this study, while the other nine predictors are non-modifiable. Understanding on issues surrounding the low SES group will help the strategic level in planning for future comprehensive interventions on overweight and obesity, specifically targeting on those predictors.
