Prevalence of hypertension in the rural adult population of Osun State, southwestern Nigeria

Abstract

BackgroundThe purpose of this study was to determine the prevalence of hypertension in two rural communities of Osun State, Nigeria.MethodsA consenting adult population of the Alajue and Obokun rural communities in southwestern Nigeria that presented for the screening exercise participated in this community-based cross-sectional descriptive study. Two hundred and fifty-nine respondents aged older than 18 years completed a standardized, pretested, structured questionnaire as part of activities celebrating World Kidney Day and World Glaucoma Day in 2011. Anthropometric data and blood pressure were recorded, and the data were analyzed using the Statistical Package for Social Sciences version 17.ResultsThe mean age of the respondents was 49.7 ± 1.6 years, 100 (38.6%) were males, 84 (32.4%) were farmers, and 111 (42.9%) were traders. The prevalence of hypertension was 13.16% (present in 34 respondents). Seventeen (6.6%) had isolated systolic hypertension, while 11 (4.2%) had isolated diastolic hypertension. Two hundred and thirty-six (91.1%) undertook daily exercise lasting at least 30 minutes and 48 (18.5%) had ever taken antihypertensive drugs on a regular basis. Four respondents (1.6%) claimed a family history of hypertension. The average body mass index (BMI) among respondents was 23.4 ± 4.9 kg/m2, 51 (19.6%) had a BMI of 25.0–29.9, and 30 (11.5%) had a BMI ≥ 30. A significant association existed between age older than 40 years and having hypertension (P < 0.05), while no relationship existed between age and BMI or between gender and hypertension (P > 0.05). Rates of older age and high BMI were significantly higher among hypertensives than among normotensives. Respondents with BMI ≥ 25 had at least a three times greater likelihood of developing hypertension than those with BMI < 25 (odds ratio 2.9, 95% confidence interval 0.007–0.056, P = 0.011).ConclusionThe prevalence of hypertension is high in this study population and we recommend scaling up primary prevention efforts to reduce this in Nigerian communities.

Prevalence of Hypertension Among Fulani Herdsmen in Rural Community of Nigeria

“…This was unlike the results of Abu Sayeedet al 30 in Bangladesh and Asekun-Olarinmoyeet al 28 in Nigeria. Also, this study was inconsistent with that of Glewet al 31 in Nigeria where the normal average BP of 120/74mmHg was observed from the herdsmen.…”

“…This was lower as compared to the findings of AsekunOlarinmoyeet al 28 in Osun State, Nigeria who reported average age of about 49 years. However, this was comparable to the study of Addoet al 29 in Ghana with average age of 42 years among the rural communities.…”

Prevalence of hypertension in three rural communities of Ife North Local Government Area of Osun State, South West Nigeria

“…Oladapo et al14 found a 20.8% prevalence of hypertension, while Onwubere et al,12 Asekun-Olarinmoye et al,18 Okeahialam et al,11 Onwuchekwa et al,19 Andy et al,20 and Ahaneku GI et al21 reported prevalence of 46.4%, 13.16%, 20.9%, 18.3%, 23.6%, and 44.5%, respectively, in their recent studies. These various studies on hypertension prevalence in Nigeria reported a wide range of prevalence rates using the BP cutoff point of 140/90 mmHg.…”

Prevalência de hipertensão arterial sistêmica em idosos no Brasil entre 2006 e 2010

“…Já em países como a Nigéria e a China, a prevalência é de 66,7% e 56,5%, respectivamente, demonstrando que países em desenvolvimento apresentam prevalências de HAS bem mais elevadas do que as dos países de alta renda. 21,22 No presente estudo, a prevalência de HAS em idosos do sexo feminino foi significativamente maior que no sexo masculino em todos os anos avaliados. Diversos estudos demonstram que as mulheres procuram mais pelos serviços de saúde, aumentando suas chances de terem o diagnóstico de HAS, 8,11,13,23 além de afirmarem que mulheres, por terem maior sobrevida que homens, ficam mais propensas a sofrerem doenças crônicas.…”
