Obesity and Hypertension, Prevalence and Correlates among Patients Seen in a Tertiary Hospital in South-south Nigeria
Background: The relevance of both hypertension and obesity as important public health challenges is increasingworld-wide. The growing prevalence of obesity is increasingly recognized as one of the most important risk factors for the development of hypertension. This study is aimed at determining the prevalence of hypertension and obesity with its associations in patients seen in a tertiary hospital in South-South Nigeria
Method: This study was carried out at the Delta State University Teaching Hospital, Oghara. It is a cross sectional descriptive study of 1045 adult patients seen at the Out-patient department between January – December 2010. Blood pressure and their anthropometric were measures taken at their first clinic visit. Overweight and obesity were determined using the body mass index (Quetelet index)
Result: The prevalence of hypertension was 28% while the prevalence of obesity was 22.1%. Specifically, 19.5% of the males and 24% of the females were obese respectively. Mean body mass index was 24.63 + 8.52kglm2. Male prevalence of hypertension was 14.4% while female prevalence was 14.1%. The prevalence of hypertension was significantly higher among obese patients compared to non-obese patients (32.5% vs. 23.5%) p<0.05.
Conclusion: Hypertension places an excessive financial burden and populations and health systems, consuming scarce resources. Body mass index is positively and independently associated with morbidity and mortality from hypertension and cardiovascular disease. Lifestyle modification would help in controlling hypertension as well as reduce its prevalence and its subsequent financial burden.
