The Prevalence and Predictors of Generalized Obesity in a Rural Farming Community in the Niger Delta Region of Nigeria

Background: Obesity, an independent risk factor for cardiovascular diseases has become a global epidemic even in the developing nations of the world. Epidemiologic transition with rapid urbanisation is important variable implicated in the rising prevalence of obesity. The prevalence of this major risk factor for cardiovascular disorders like hypertension, heart failure, coronary artery disease etc has not been richly studied in the rural setting of the Nigerian Niger Delta region despite the increasing urbanisation taking place in same region. The aim of this research therefore is to determine the prevalence and predictors of obesity in a rural farming community of the Niger Delta region of Nigeria Methods: A cross sectional study involving 388 subjects aged 15 years and above. Demographic social and relevant medical information and social information were obtained using a questionnaire administered by face-to-face interview. Anthropometric (height, weight, waist circumference, Waist-Hip-Ratio) and blood pressure measurements were done. Blood samples were taken for fasting blood sugar.Results: The overall mean age of the study subjects was 40.88±16.52. The mean age for males was 40.66±17.23 and that for females was 40.98±16.17. The male to female ratio was 1:2.1. The prevalence of generalised obesity in this study was 3.4% .The females had a higher prevalence than the males (p= 0.02). The prevalence of obesity found to be highest in the 50 to 59 years age group. Pearson and Spearman' rho correlation analysis of BMI with other parameters revealed that educational status, waist circumference, and hypertension had significant association while logistic regression confirmed these variables as well as physical inactivity as predictors of obesity. Conclusion: The prevalence of obesity in this rural community is 3.4% and educational status, waist circumference and hypertension are important predictors

EPIDEMIOLOGY OF DIABETES AND IMPAIRED FASTING GLUCOSE IN A RURAL COMMUNITY OF NIGERIAN NIGER DELTA REGION.

BACKGROUND: The prevalence of diabetes mellitus is reaching epidemic rates globally. It had an estimated global incidence of 220 million in 2010. Different studies in SSA and Nigeria in particular have reported increasing prevalence of diabetes in the rural areas. This may be attributed to the rapid 'westernization' of lifestyle in the rural African community.Only few rural survey have been conducted in the Nigeria oil-rich Niger Delta region necessitating this study with the aim of determining the prevalence of diabetes and impaired fasting glucose (IFG). METHODS: This was a cross-sectional survey involving 500 subjects aged 15 years and above in a typical rural community of Rivers State, Niger Delta region of Nigeria. A questionnaire administered by face-to-face interview was used to assess socio-demographic characteristics of the subjects. Medical history such as prior knowledge of blood sugar status and family history of diabetes were all elicited by the questionnaire. Anthropometric and blood pressure measurements were taken in a standardized manner and body mass indices (BMI) calculated as weight in kilogram divided by the square of height in meters. Venous blood glucose was measured by the glucose oxidase method. Diabetes mellitus was defined using fasting plasma glucose (FPG) ≥ 7.0 mmol/l (126 mg/dl) and individuals who were previously known to have diabetes based on history of treatment were also classified to have diabetes. Lipid profile and uric acid of patients were also checked. RESULTS: There were 156 males and 344 females with male to female ratio of 1:2.3.The females were relatively of younger age than the males (40.62 ± 16.6 years versus 42.84 ± 17.8).The overall mean age was 41.32 ± 17. The mean fasting plasma glucose among those with diabetes was 11.14?4. 00mmol/L while the mean for the subjects with impaired fasting glucose was 6.31 ± 0.25 mmol/l. The prevalence of diabetes was 2.2% with no significant gender difference (2.6% in males versus 2.0% in females; χ2 = 0.35; p = 0.84). The prevalence of Impaired fasting glucose (IFG) was 2.4%with no significant gender difference (Female 2.6% versus males 1.9%; p = 0.88). The mean fasting glucose increased significantly with blood pressure (p = 0.05), waist circumference (p < 0.001), uric acid level (0.02), triglyceride level (< 0.001) and age (p = 0.02).The correlation analyses showed that age, systolic blood pressure, waist-hip-ratio and triglycerides are positively correlated with diabetes and impaired fasting glucose in this study. CONCLUSION: There is a low prevalence of diabetes and IFG in this rural community which may be associated to the high level of physical activity found among the study subjects in this community. However, this study confirmed that increasing age, abdominal obesity, systolic blood pressure and triglyceride level have positive relationship with the prevalence of diabetes and IFG. There is hence more need for intensified screening for diabetes, pre-diabetes and associated risk factors in order to curb or at least reduce diabetes prevalence and its attendant complications.

Prevalence of hyperuricaemia in a rural population of Nigerian Niger Delta region.

INTRODUCTION: Hyperuricemia is a cardiovascular disease risk factor that has been poorly researched into in Africa and its prevalence is largely unknown in the rural areas in Nigeria and in the Niger Delta region of Nigeria in particular. METHODS: A cross-sectional rural survey involving 500 subjects aged 15 years and above. Demographic and social data were obtained using a questionnaire. Anthropometric (height, weight, waist circumference) and blood pressure measurements were taken. Blood samples were taken for blood uric acid, glucose and lipid check. RESULTS: The mean age of the study subjects was 41.32 +/- 17.0 (males, 42.84 +/- 17.8; females, 40.62 +/- 16.6) with a range of 15 years to 95 years. The male to female ratio was 1:2.3. The mean serum uric acid was 337.58 +/- 94.59 mmol/l with a significant higher mean for females (males 333.20 +/- 88.70, females 339.56 +/- 97.21, p < 0.001). Hyperuricemia was found in 86 subject giving a prevalence of 17.2% with higher prevalence in males (males 25%, females 13.7%; x2 = 7.75, p = 0.006). Correlational analysis of serum uric acid with other parameters revealed that waist circumference, total cholesterol, low-density lipoprotein and gender had significant association with uric acid. Male gender was found to be a significant predictor for hyperuricaemia following a logistic regression. CONCLUSION: The prevalence of hyperuricemia is high in this rural community of study. There is need for more research considering the cardiovascular and other implications of hyperuricaemia.
