Prevalence and factors associated with overweight and obesity in selected health areas in a rural health district in Cameroon: a cross-sectional analysis.

BACKGROUND: Overweight and obesity are major public health problems worldwide, with projections suggesting a proportional increase in the number of affected individuals in developing countries by the year 2030. Evidence-based preventive strategies are needed to reduce the burden of overweight and obesity in developing countries. We assessed the prevalence of, and factors associated with overweight and obesity in selected health areas in West Cameroon. METHODS: Data were collected from a community-based cross-sectional study, involving the consecutive recruitment of participants aged 18 years or older. Overweight and obesity were defined according to the WHO classification. The statistical software R (version 3.5.1, The R Foundation for statistical computing, Vienna, Austria) was used for statistical analysis. Multivariable logistic regression analysis was used to assess independent factors associated with overweight and obesity, and obesity. RESULTS: Records of 485 participants were included for analysis. The age and sex-standardized prevalence of overweight, obesity, and overweight and obesity were 31.1% (95% CI, 27.0-35.2), 18.9% (95% CI, 14.9-22.9), and 50.1% (95% CI, 45.7-54.6), respectively. In multivariable analysis, being female (adjusted OR [aOR] = 2.79, 95% CI = 1.69-4.63), married (aOR = 3.90, 95% CI = 2.23-6.95), and having secondary or tertiary education (aOR = 3.27, 95% CI = 1.77-6.17) were associated with higher odds of overweight and obesity, while current smokers had lower odds of overweight and obesity (aOR = 0.37, 95% CI = 0.16-0.82) when compared to their respective counterpart. Compared to their respective reference categories, being female being (aOR = 3.74, 95% CI = 2.01-7.30), married (aOR = 2.58, 95% CI = 1.37-5.05) and having secondary or tertiary education (aOR = 2.03, 95% CI = 1.00-4.23) were associated with higher odds of obesity after adjustments for confounding. CONCLUSION: We observed a high prevalence of overweight and obesity in this study. The odds of overweight and obesity was higher in females, married participants, and those with higher levels of education. Community-based interventions to control overweight and obesity should consider targeting these groups.

Prescription of pharmacotherapy and blood pressure control among hypertensive outpatients in two semi-urban hospitals in Cameroon: a cross-sectional study.

INTRODUCTION: several international guidelines are available on drug treatment for hypertension, but the control of hypertension remains very poor in sub-Saharan Africa (SSA). We investigated the commonly prescribed antihypertensive drugs and their association with blood pressure (BP) control in adult Cameroonians. METHODS: we consecutively recruited hypertensive outpatients attending the Buea and Limbe Regional Hospitals (southwest region of Cameroon). Controlled BP was defined as BP < 140/90mmHg in hypertensive patients aged 60 years or younger, diabetics or patients with chronic kidney disease or a BP < 150/90mmHg in non-diabetic hypertensive patients older than 60 years of age (JNC8). RESULTS: of the 408 participants included (mean age 61.1 years), 67% were female. The median duration of hypertension was 6 years and the median duration of the current treatment was 22 weeks. Commonly prescribed antihypertensives were calcium channel blockers (CCB, 35.1%), thiazide/thiazide-like diuretics (TD/TLD, 26.1%) and angiotensin-converting enzyme inhibitors (ACEI, 19.5%). The median monthly cost of antihypertensive was 10279.6 CFA (approximately equal to US$ 172). Seventy percent (70%) of participants were receiving at least 2 drugs, with ACEI+TD/TLD, CCB+TD/TLD, and ACEI+CCB+TD/TLD being the most frequent combination. The rate of BP control was 52% overall, and 60% in participants on monotherapy. CONCLUSION: CCBs were the most prescribed single antihypertensive drugs in this setting while ACEI+TD/TLD was the most common combination. About half of patients were at target BP control levels Improving availability and affordability of these medications may improve hypertension management and control.
