Prevalence of obesity among adults in Otjomuise Community in Namibia

Obesity is a major contributor to non-communicable diseases (NCDs) and is rising in socioeconomically disadvantaged communities with limited health literacy and access to nutritious food. Namibia, like many African countries, faces increasing obesity rates because of dietary and lifestyle transitions. Community-based screening is essential for early identification and prevention.

This study aimed to determine the prevalence of obesity among community members in Otjomuise, Namibia.

The study was conducted at a community health care clinic in Otjomuise, Namibia.

A cross-sectional, descriptive study was conducted with 335 adults. Body mass index (BMI) was calculated and classified according to Centers for Disease Control and Prevention (CDC) categories: underweight, healthy weight, overweight, or obese.

Of the 335 participants, 67.2% (n = 225) were female and 32.8% (n = 110) male. Overall, 9.3% (n = 31) were underweight, 48.7% (n = 163) had a healthy weight, 26.6% (n = 89) were overweight, and 16.7% (n = 56) were obese. Mean BMI was 22.92 ± 4.64 kg/m² for males and 26.76 ± 6.28 kg/m² for females.

Less than half of the participants had a healthy BMI, with notable overweight and obesity prevalence, particularly among women. These findings align with regional and global trends and underscore the need for targeted public health strategies.

This study provides updated obesity data for Namibia and supports community-based screening as a tool for surveillance and intervention. It highlights the importance of multisectoral approaches promoting diet, physical activity, and health education to reduce NCD risk.
