Abstract
AIMS: We aimed to evaluate the risk of cardiovascular disease (CVD) in women with polycystic ovary syndrome (PCOS) and estimate the global incidence of PCOS-associated CVD. METHODS AND RESULTS: We conducted a meta-analysis across five databases to evaluate the risk of CVD among women with PCOS. The global incidence of PCOS-associated CVD was calculated by a population attributable fraction modelling using the pooled risk ratio (RR), PCOS prevalence, CVD incidence number, and age-standardized rate (ASIR), from the Global Burden of Diseases 2019. An estimated annual percentage change (EAPC) was used to assess the temporal trend of PCOS-associated CVD. The risk of CVD was significantly increased in women with PCOS for an all-age group (pooled RR 1.51, 95% confidence interval 1.36-1.69) and 10- to 54-year-olds (1.37, 1.17-1.59). Globally, from 1990 to 2019, the PCOS-associated CVD cases in women across the all-age group has raised from 102 530 to 235 560. The most affected regions were East Asia and the Pacific (108 430, 66 090-166 150) in 2019. South Asia has the highest increase trend of PCOS-associated CVD ASIRs (EAPC 2.61%, 2.49-2.73). The annual increase in ASIR in PCOS-CVD incidence for the 10-54 age group (EAPC 0.49%, 0.41-0.56) is faster than that of the all-age group (0.34, 0.27-0.42). The middle- or low-middle sociodemographic index countries experienced higher increase trend of CVD due to PCOS in the past 30 years. CONCLUSION: Women with PCOS have a significantly increased risk of CVD. Efficient measures to enhance its prevention and treatment are important for regions with a high PCOS-associated CVD burden, especially premature CVD in women under 55 years.
