The prevalence estimates of hypertension obtained in this study was higher than those found in most earlier studies from Nigeria, other West Africa nations and for African-Americans.

Frequent reports of haematuria among resettlers at Ibaro and Abule-titun located close to a newly constructed reservoir. 20 km north-west of Abeokuta. Ogun State, Nigeria. prompted a pre-control survey to assess age and sex distribution of urinary schistosomiasis in the communities. 210 persons were examined at Ibaro and 145 at Abule-titun between April 1988 and February 1989. Overall prevalence was about 80% in both villages, and all age and sex groups examined were affected. The pattern of infection in both villages was similar, prevalence being high in all age and sex groups and, unlike most endemic communities, the rate of infection was not significantly higher among the 5–14 year age groups. Intensity of infection was also high in all age and sex groups with mean range egg output of between 73±73 and 2016±3875 ova/10ml urine at Ibaro and between 231±122 and 1340±1786 ova/10ml urine at Abule-titun. This is attributed to an occupation-related high rate of human water contact in both villages.

BackgroundLimited data exist on the prevalence of overweight and obesity in the Nigerian adult rural population. This study therefore assessed the prevalence and pattern of overweight and obesity in adults in three rural communities of the Ife North Local Government Area, Nigeria.Materials and methodsA total of 777 adults between 20 and 90 years of age were recruited into this cross-sectional study, which was performed over a 6-month period using a multistage proportional stratified random sampling technique. Sociodemographic data and anthropometric variables were obtained.ResultsA total of 385 (49.5%) men and 395 (50.5%) women participated in the study. The mean age and body mass index of the participants were 36.3±14.3 years and 23.53±4.6 kg/m2, respectively. The overall crude prevalence of overweight and obesity in the total population were 20.8% and 8.4%, respectively. Obesity increased across the age gradient, peaking in the 51- to 60-year age-group in men and women. Among the overweight and obese subjects (n=227), 70.9% of them were overweight and the remaining 29.1% were obese, with class I obesity accounting for 20.7% of these overweight and obese subjects.ConclusionThe prevalence of overweight and obesity in these communities was 20.8% and 8.4% respectively, indicating a trend towards increased prevalence. Class I obesity is the most common obesity pattern, and obesity increased across the age gradient, peaking in the 51- to 60-year age-group. There is a need for regular community education on healthy lifestyles, and regular health screening to control the rising prevalence of overweight and obesity, as well as to prevent or reduce the risk of obesity comorbidities in these communities.

BackgroundThe prevalence of hypertension is increasing rapidly in sub-Saharan Africa, but data are limited on hypertension prevalence. In addition, few population-based studies have been conducted recently in Nigeria on the prevalence and correlates of hypertension in both urban and rural communities. Therefore, we determined the prevalence of hypertension in adults in the three rural communities of Ipetumodu, Edunabon, and Moro, in South West Nigeria.Materials and methodsOne thousand adults between 15 and 90 years of age were recruited into this cross-sectional study, over a 6-month period, using a multistage proportional stratified random sampling technique. Sociodemographic data and anthropometric variables were obtained, and resting blood pressure (BP) was measured using an electronic sphygmomanometer. Diagnosis of hypertension was based on the JNC VII guidelines, the WHO/ISH 1999 guidelines, and the BP threshold of 160/95 mmHg.ResultsFour hundred and eighty-six men (48.6%) men and 514 women (51.4%) participated in the study. Their mean age, weight, height, and body mass index were 32.3±14.7 years, 62±13 kg, 1.5±0.1 m, and 23.02 kg/m2, respectively. The prevalence of hypertension, based on the 140/90 mmHg definition, was 26.4% (Male: 27.3%; Female: 25.4%). The prevalence of hypertension, based on the 160/95 mmHg definition, was 11.8% (Male: 13.5%; Female: 10.1%). There were significant positive correlations between BP and some anthropometric indicators of obesity.ConclusionThe prevalence of hypertension in the three rural communities was 26.4%, indicating a trend towards increasing prevalence of hypertension. There was also a significant positive correlation between anthropometric indicators of obesity and BP in this population.
