Prevalence and sociodemographic determinants of dyspepsia in the general population of Rwanda

BMJ Open Gastroenterol. 2020 May;7(1):e000387. doi: 10.1136/bmjgast-2020-000387.

Abstract

Introduction: Dyspepsia accounts for a significant burden of worldwide disease, but there is a relative paucity of data from the sub-Saharan African setting. We undertook to describe the burden, risk factors and severity of dyspepsia across Rwanda.

Methods: We performed a population-based clustered cross-sectional survey between November 2015 and January 2016, nationwide in Rwanda, using the Short Form Leeds Dyspepsia Questionnaire to describe the presence and severity of dyspepsia, and the Short Form Nepean Dyspepsia Index to describe the concomitant quality of life effects. Univariate and multivariate logistic regression models were constructed to correlate measured sociodemographic factors with dyspepsia.

Results: The prevalence of clinically significant dyspepsia in the general Rwandan population was 14.2% (283/2000). The univariate factors that significantly predicted severity were gender, profession, socioeconomic status, and non-steroidal anti-inflammatory drug, aspirin and alcohol use, with gender, current smoking, aspirin use both in the past and currently, and alcohol use in the past remaining significant on multivariate modelling. Dyspeptics had a significantly lower gastrointestinal-related quality of life, though the sociodemographic factors measured did not modify the observed quality of life.

Conclusion: Dyspepsia is prevalent in the Rwandan setting and is associated with a significant burden on quality of life. More work is required to determine the pathological entities involved, and the optimal approach to mitigating this burden.

Keywords: dyspepsia; epidemiology; quality of life.
