Prevalence, pattern and determinants of chronic disease multimorbidity in Nepal: secondary analysis of a national survey

Abstract

ObjectivesTo assess the prevalence, pattern and determinants of non-communicable diseases (NCDs) multimorbidity in Nepal.DesignSecondary analysis of the data from the NCD survey 2018, which was conducted between 2016 and 2018.SettingThe data belong to the nationally representative survey, that selected the study samples from throughout Nepal using multistage cluster sampling.Participants8931 participants aged 20 years and older were included in the study.Primary outcomesNCD multimorbidity (occurrence of two or more chronic conditions including hypertension, diabetes, chronic obstructive pulmonary disease, chronic kidney disease, coronary artery disease and cancer). Descriptive statistics, prevalence ratio and odds ratio were computed to assess pattern and determinants of multimorbidity.ResultsMean (SD) age was 46.7 years (14.9 years). The majority of the participants were women (57.8%), without formal education (53.4%) and from urban areas (51.5%). Multimorbidity was present in 13.96% (95% CI: 12.9% to 15.1%). Hypertension and diabetes coexisted in 5.7%. Age, alcohol consumption, body mass index, non-high-density lipoprotein (non-HDL) level and rural–urban setting were significantly associated with multimorbidity.ConclusionMultimorbidity was prevalent in particular groups or geographical areas in Nepal suggesting a need for coordinated and integrated NCD care approach for the management of multiplicative co-comorbid conditions.
