Risk factors for diabetes mellitus and hypertension among artisans in Ogun state, Nigeria

Abstract

Purpose This study was designed to assess the risk factors associated with hypertension (HTN) and diabetes among artisans in Ogun State, Nigeria. Evidences suggest increasing prevalence, incidences and morbidity of diabetes and HTN in Nigeria. However, the purpose of this study is to plan and prioritize effective intervention programs, there is need to provide data on the prevalence and risk factors for HTN and diabetes among local groups. Design/methodology/approach In total 300 apparently healthy artisans who have never been diagnosed of diabetes or HTN were randomly selected from five communities. A structured questionnaire was used in obtaining information on the personal characteristics of the respondents. An adapted dietary habit and lifestyle questionnaire were used to assess the dietary habits and lifestyle of the respondents. The WHO global activity questionnaire was adapted and used to gather information on the physical activity level of the respondents. Random blood glucose, blood pressure and anthropometric measurements were assessed using standard instruments. Chi-square (χ2), correlations and multinomial logistic regression analysis were performed to identify significant determinants of diabetes and HTN. Findings Mean age was 34.8 ± 9.9 and prevalence of diabetes and pre-diabetes were 1 and 4.7 per cent, respectively, while HTN and pre-HTN were 48.0 and 30.3 per cent, respectively. About half (55.7 per cent) of the respondents skip at least a meal daily and 31 per cent snack daily. Most (61.4 per cent) consume alcohol and 65.7 per cent engage in high physical activity. Abdominal obesity was significantly higher among women (p = 0.004). Using the chi-square analysis, age, abdominal obesity and educational status were factors found to be significantly associated with diabetes (p = 0.002; p = 0.007; p = 0.004) while age, gender, abdominal obesity and alcohol consumption had significant association with HTN. Although not statistically significant, respondents were 0.8, 1.0 and 1.1 times more likely to be diabetic with increasing body mass index, waist circumference (WC) and age (odd ratio (OR) = 0.78; confidence intervals (CI): 0.51-1.18; OR = 1.04; CI: 0.89-1.21; OR = 1.06; CI: 0.96-1.18, respectively). Abdominal obesity was significantly associated with HTN (OR = 1.08; CI: 1.03-1.13; p = 0.001). Also, older respondents were 1.1 times more likely of becoming hypertensive (OR = 1.07; CI: 1.02-1.11; p = 0.003). Increased risk of diabetes and HTN was found among respondents with increasing age and WC. Research limitations/implications This study was cross-sectional in design; it cannot be used to establish a cause-effect relationship between diabetes, HTN and the observed variables (anthropometric characteristics, dietary habits and lifestyle risk factors). Because of the few numbers (1 per cent) of respondents identified to be diabetic several important risk factors could not be included in the model. Practical implications An understanding of the risk factors associated with diabetes and HTN among sub-groups in the population will help to plan effective interventions targeted at specific groups. Originality/value The findings of this study show the associated risk factors for diabetes and HTN among artisans in Ogun State.
