Age-standardised trends in Incidence Rates of Noncommunicable diseases among Adults Aged 30 to 79 in Senegal from 2000 to 2019

Introduction: Non-communicable diseases (NCDs) represent a significant global health burden in sub-Saharan Africa (SSA). However, most SSA countries such as Senegal lack reliable data despite the need for surveillance of NCD trends to inform targeted preventive strategies. Methods: We used publicly available data from the Global Burden of Disease Study (World Health Organization's Health Inequality Data Repository). We used age-standardised regression to analyze the trends of NCDs (cancers, cardiovascular diseases, chronic respiratory diseases, diabetes, and chronic kidney diseases) incidence among adults in Senegal. Statistical analysis was performed using the Joinpoint Regression Program, Version 5.3.0.0 and data visualization was performed using R, version 4.4.0. Results: NCD incidence rates in females were consistently higher than in males. Rates in females increased from 190,857 to 194,620 cases per 100,000 population between 2000 and 2019 (p-value 0.007) as compared to 160,623 to 163,800 cases per 100,000 population in males (p-value 0.002). Incidence rates were higher in females for neoplasm (p-value 0.03), chronic respiratory diseases (p-value 0.07), and diabetes and chronic kidney diseases (p-value 0.04), while cardiovascular disease incidence was higher in males (p-value 0.02). Conclusion: There was a significant increase in age-standardised NCD incidence among adults in Senegal. When considering subtypes, all had increased incidence rates, except cardiovascular diseases which showed a significant decrease over time. A national NCD registry and targeted risk factor prevention programs are crucial to help tackle the NCD burden in Senegal.
