Abstract:
Obesity is a risk factor for hypercholesterolemia; however, evidence of obesity among Orang Asli (OA) adults remains limited. Lifestyle changes, including unhealthy diets and sedentary behavior, may increase vulnerability to noncommunicable diseases. This study examined the sex-specific associations between body mass index (BMI) and hypercholesterolemia using data from the OA Health Survey 2022. A total of 8160 adults aged ≥18 years with complete questionnaires, anthropometric data, and blood data were analyzed. The prevalence of hypercholesterolemia among OA adults was 47.6%; of these, 41.5% were previously undiagnosed. Compared with normal BMI, overweight and obesity were associated with a higher odds of hypercholesterolemia in both sexes. Older age, Senoi tribe affiliation, and diabetes were associated with hypercholesterolemia in both sexes. These findings highlight the need for culturally tailored interventions to strengthen obesity prevention and cholesterol testing in primary care and outreach services to reduce cardiovascular risk in OA communities.
