Prevalence of Self-Reported Chronic Non-Communicable Diseases among Adults in Addis Health and Demographic...

Chronic non-communicable diseases (NCDs) are a global health challenge, causing millions of deaths annually and contributing significantly to the global disease burden. Despite their prevalence in low- and middle-income countries (LMICs), NCDs receive limited global health financing. Ethiopia, like other LMICs, is experiencing a rising burden of NCDs. This study aimed to assess the self-reported prevalence of chronic NCDs and identify associated sociodemographic factors.

A population-based cross-sectional study was conducted at the Addis Health Demographic Surveillance System (Addis-HDSS) site in Addis Ababa, Ethiopia. All adults (≥18 years) living in the Addis-HDSS sites were included. Data were collected using a structured electronic questionnaire on self-reported NCDs and sociodemographic variables. Binomial regression model was used to identify sociodemographic factors associated with self-reported NCDs.

Overall, 11.5% (95% CI: 11.3%-11.7%) of adults reported at least one NCD. The most prevalent conditions were hypertension (5.9%; 95% CI: 5.7%-6.1%) and diabetes mellitus (3.4%; 95% CI: 3.3%-3.5%). Older age (Adjusted Incidence Rate Ratio (AIRR): 5.47; 95% CI: 5.17-5.79), no formal education (AIRR: 1.58; 95% CI: 1.45-1.72), being formerly married (AIRR: 2.68; 95% CI: 2.47-2.91), and higher wealth quintiles (AOR: 1.16; 95% CI: 1.07-1.26) were statistically significant risk factors associated with NCDs.

This study highlights the high burden of chronic NCDs among adults in Addis Ababa. The findings highlight the importance of addressing NCDs as a significant public health challenge. Expanding access to early prevention, diagnosis, and care is critical in urban settings.
