Revealing the burden of chronic kidney disease in Mexican women, 1990-2021.

BACKGROUND

Chronic kidney disease (CKD) has become a concerning public health issue, affecting people regardless of their sex, age, or socioeconomic status. We aimed to analyze the burden of female CKD in Mexico between 1990 and 2021, expressed in terms of years lived with disability (YLDs), mortality, years of life lost (YLLs), and disability-adjusted life-years (DALYs). Additionally, we evaluated the relationship between DALYs and the Socio-Demographic Index (SDI) and the Healthcare Access and Quality Index (HAQI).

METHODS

Secondary data analysis from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021. We used mortality, years of life lost due to premature mortality (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs to analyze CKD in women between 1990 and 2021. We used a log-linear segmented regression model to analyze trends in female CKD DALY rates over time. The information was disaggregated by age groups and sub-causes nationally and across the 32 states. Age-standardized rates (ASR) were used.

RESULTS

Between 1990 and 2021, the ASR mortality and ASR-DALYs due to CKD increased significantly at the national level. The DALYs are almost entirely explained by YLLs, indicating that a large proportion of women with CKD in Mexico die prematurely. Disparities in the burden of this disease were observed across different states and age groups within the country. In 2021, the highest ASR-DALY rate was recorded in Tabasco (1,972.0), while the lowest was in Sinaloa (865.1). The SDI and HAQI were associated with the CKD DALYs in most states.

CONCLUSIONS

Mexican women experience a significant burden due to CKD, reflected in premature deaths and years lived with disability, while disparities between states need to be addressed to reduce inequities. Over the past 32 years, improvements in socioeconomic indicators and the quality and access to healthcare have not contributed to reducing the DALYs rate due to CKD, indicating a need to redirect policies to impact women's well-being and health positively.
