The burden and risk factors of NCDs in Zimbabwe: evidence from the Zimbabwe population based HIV impact assessment 2020 survey.

BACKGROUND

The burden of non-communicable diseases (NCDs) has emerged as a critical public health challenge in Zimbabwe, exacerbated by a complex interplay of socioeconomic factors, demographic shifts, and urbanization. This study leverages data from the Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA) 2020 survey to provide further insights and understanding of the prevalence and risk factors associated with NCDs in the country.

METHODS

Utilizing a two-stage, stratified cluster sample design, we analyzed data from 19,535 participants. We conducted univariate and multivariate logistic regression analyses to evaluate the relationship between self-reported NCDs and demographic factors, including age, gender, urban versus rural residency, HIV status, and socioeconomic status.

RESULTS

Findings revealed that approximately 14.3% of the population reported being diagnosed with at least one NCD, with hypertension and diabetes presenting prevalences of 10.8% and 2.2%, respectively. Age was a significant predictor of NCD burden, and we also noted disparities, particularly among women and individuals in higher wealth quintiles.

CONCLUSION

Approximately one in seven Zimbabwean adults had been diagnosed with at least one non-communicable disease before 2020, with hypertension and diabetes the most common conditions. Older age increases NCD risk, and women and people in higher wealth quintiles carry a higher burden. These patterns suggest the need to keep prioritizing NCD prevention, screening, and management.
