Prevalence and correlates of multimorbidity among adults in Botswana: A cross-sectional study.

BACKGROUND: Botswana is currently undergoing rapid epidemiological transition indicated by a decline in infectious diseases and an increase in chronic non-communicable diseases and their associated risk factors. The main aim of this study was to assess prevalence and correlates of multimorbidity among the adult population in Botswana. METHODS: A cross-sectional study called Chronic Non-Communicable Diseases Study (NCDs study) was conducted in March, 2016. Using multistage cross sectional sampling design, 1178 male and female respondents aged 15 years and above were interviewed across 3 cities and towns, 15 urban villages and 15 rural villages. Participants were interviewed face-to-face using a structured questionnaire. Adjusted multinomial logistic regression analysis was used to assess covariates of multimorbidity. The statistical significant level was fixed at p <0 .05. RESULTS: Prevalence of multimorbidity in the sampled population was estimated at 5.4%. Multivariate results indicate that the odds of multimobridty were significantly high among women (AOR = 3.34, 95% C.I. = 1.22-21.3) than men. On the other hand, the odds of multimorbidity were significantly low among young people aged below 24 years (AOR = 0.01, 95% C.I. = 0.00-0.07), currently married people (AOR = 0.24, 95% C.I. = 0.07-0.80) and individuals in the 2nd wealth quintile (AOR = 0.20, 95% C.I. = 0.05-0.75) compared to their counterparts. For behavioural risk factors, alcohol consumption (AOR = 4.80, 95% C.I. = 1.16-19.8) and overweight/obesity (AOR = 1.44, 95% CI = 1.12-2.61) were significantly associated with high multimorbidity prevalence. CONCLUSION: Multimorbidity was found to be more prevalent among women, alcohol consumers and overweight/obese people. There is need to strengthen interventions encouraging healthy lifestyles such as non-consumption of alcohol, physical activity and healthy diets. Moreover, there is need for a holistic approach of health care services to meet the needs of those suffering from multimorbidity.

Prevalence and correlates of self-reported chronic non-communicable diseases in Botswana: a cross-sectional study.

BACKGROUND: The purpose of this paper is to estimate the prevalence of self-reported chronic non-communicable diseases and their correlates in Botswana. This is a nationally representative, cross-sectional survey. METHODS: This is a cross-sectional study of respondents aged 10-64 years using data from the Botswana AIDS Impact Survey IV conducted in 2013. Three self-reported non-communicable diseases, namely, hypertension, diabetes and asthma were used. Multivariate logistic regression models were used to identify their correlates. RESULTS: Out of the 2153 participants, the prevalence rates of hypertension, diabetes and asthma were 14.2%, 3.3% and 5.3%, respectively. The study found that among other factors, older populations are at a much higher risk of having more than one non-communicable disease. After controlling for other covariates, the ORs of self-reported non-communicable disease was highest among older respondents aged 50 years and over (AOR=12.01, p<0.001) followed by richer respondents (AOR=1.86, p≤0.025). The ORs were also higher among females (AOR=1.83, p<0.001) and urban village residents (AOR=1.41, p=0.038). CONCLUSIONS: It is evident that chronic non-communicable diseases are likely to increase in the future due to the rise in the old age population resulting from fertility transition and improvement in life expectancy in Botswana. Therefore urgent and holistic intervention programmes are required to halt the problem. Failure to act now is likely to result in high morbidity and mortality.
