Background:Metabolic syndrome (MetS) is an important cause of morbidity and mortality. Nigeria is currently undergoing rapid epidemiological transition. The objective was to study whether urbanization is associated with increased prevalence of MetS between native rural Abuja settlers and genetically related urban dwellers.Materials and Methods:It was a cross-sectional study. Three hundred and forty-two urban native Abuja settlers and 325 rural dwellers were used for the study. Fasting blood lipid, glucose, waist circumference, blood pressure, and body mass index were determined. MetS was defined according to three standard criteria. SPSS 16.0 was used for statistical analysis. P<0.05 was used as statistically significant.Results:Obesity, hypertriglyceridemia, and hypertension were commoner among urban dwellers than rural dwellers. MetS was associated more with the female gender. Urbanization significantly increases the frequency of MetS using the three standard definitions. The prevalence of MetS using International Diabetes Federation, World Health Organization, and National Cholesterol Education Program Adult Treatment Panel III among rural versus urban dwellers were 7.7% vs. 14.9%, P<0.05; 0% vs. 0.9%, P>0.05; and 3.7% vs. 13.7%, P<0.05, respectively.Conclusion:This study shows that MetS is a major health condition among rural and urban Nigerians and that urbanization significantly increases the prevalence of MetS. This can be explained on the basis of higher prevalence of dyslipidemia, obesity, and hypertension in urban setting, possibly as a result of stress, diet, and reduction in physical activity. Effective preventive strategy is therefore required to stem the increased risk associated with urbanization to reduce the cardiovascular risk associated with MetS among Nigerians.
BackgroundPeripheral arterial disease (PAD) is rarely sought for and generally under-diagnosed even in diabetics in developing countries like Nigeria. PAD is easily detected and diagnosed by the ankle-brachial index, a simple and reliable test.ObjectivesTo determine the prevalence of PAD in diabetic subjects aged 50–89 years and the value of ankle-brachial index measurement in the detection of PAD.MethodA cross-sectional descriptive study of 219 diabetic subjects aged 50–89 years was carried out. The participants were administered a pre-tested questionnaire and measurement of ankle-brachial index (ABI) was done. The ankle-brachial index < 0.90 was considered equivalent to peripheral arterial disease.ResultsThe overall prevalence of PAD was 52.5%. The prevalence of symptomatic PAD was 28.7% whilst that of asymptomatic PAD was 71.3%. There were a number of associations with PAD which included, age (p < 0.05), sex (p < 0.05), and marital status (p < 0.05). The use of the ankle-brachial index in the detection of PAD was clearly more reliable than the clinical methods like history of intermittent claudication and absence or presence of pedal pulses.ConclusionThe prevalence of PAD is relatively high in diabetic subjects in the south-western region of Nigeria. Notable is the fact that a higher proportion was asymptomatic. Also the use of ABI is of great value in the detection of PAD as evidenced by a clearly more objective assessment of PAD compared to both intermittent claudication and absent pedal pulses.
BackgroundThere is an increase of obesity and other cardiovascular risk factors worldwide, but especially in developing countries where multifaceted transitions are occurring. There is need for more evidence for the cardio-metabolic effect of changing lifestyles and urbanization in Nigeria. This study aimed at defining rural–urban differences in anthropometric parameters in two Nigerian communities of the same ancestral origin and to determine the cardiovascular risk correlates of these anthropometric measurements. This was a cross-sectional epidemiological study using stratified cluster sampling method. We studied 335 and 332 urban and rural dwellers respectively. A complete cardiovascular profile as well as anthropometric measurements was compared between the two populations.ResultsAll anthropometric indices considered in this study (weight, BMI, waist circumference, waist circumference/height ratio, abdominal height; biceps, triceps, sub-scapular, abdominal, superior iliac skinfold thicknesses) were significantly higher in urban than in the rural population (p = <0.001). Overweight, obesity and hypertension were significantly prevalent among the urban population (p = <0.001) while there was no significant difference in the prevalence of dyslipidaemia (p = 0.096) and diabetes (p = 0.083) between the two cohorts. Females tend to have a higher chance of obesity than males although there was no gender difference in waist circumference and central skin fold thickness in the rural population. Age was the significant predictor of systolic blood pressure among the rural (R2 = 0.157, β = 0.258, p = 0.016) and urban female population (R2 = 0.201, β = 0.351, p = <0.001) while Abdominal height (R2 = 0.16, β = 0.281, p = 0.001) and waist circumference (R2 = 0.064 β = 0.064, p = .003) were predictors of systolic blood pressure in urban and rural men respectively.ConclusionAnthropometric indices were significantly higher among the urban than the rural populations. Cardiovascular risks were equally more prevalent among the urban population. Appropriate health education and lifestyle modification strategies may reduce the increased burden of cardiovascular risk factors associated with rural–urban migration.
