Description
Objective: To compare the effects of age, period, and cohort on DM mortality between Colombia and Spain from 1983 to 2022.
Methods: Analytical observational study using aggregated cross-sectional data from mortality records and population projections of both countries. DM deaths for each age, period, and cohort group were organized into five-year intervals. Age-standardized mortality rates (ASMR) and their 95% confidence intervals (CIs) were calculated. A multiple quasi-Poisson model was applied using the intrinsic estimator method. Adjusted mortality rate ratios (MRR) with 95% CIs for each age, period, and cohort group compared to the overall average rate were estimated.
Results: The annual ASMR in Colombia was 17.5 (95% CI 17.4–17.6), while in Spain it was 9.9 (95% CI 9.8–9.9). Period effects differed between countries. In Colombia, the MRR increased from 1983 to 2007 and then decreased between 2008 and 2017. In Spain, a consistent decline was observed from 1983 to 2017. Both countries showed an increase in MRR from 2018 to 2022. DM mortality rose with age, with the 85+ group showing the highest MRR (Colombia: 18.5; 95% CI 16.9–20.3; Spain: 91.8; 95% CI 51.9–162.2). Older cohorts also had higher MRRs. For the 1913–1917 cohort, MRR was 3.6 (95% CI 3.3–3.9) in Colombia and 4.2 (95% CI 3.1–5.6) in Spain.
Conclusion: Public health actions to reduce DM mortality should ensure healthy aging and continuous management of complications and comorbidities, particularly in older adults. Awareness of health care must be prioritized for younger generations.
