  • Prevalence of osteoporosis in Chinese postmenopausal females: a meta-analysis

    Objective To systematically review the prevalence of osteoporosis (OP) in Chinese postmenopausal females. Methods The CNKI, VIP, CBM, WanFang Data, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect studies on the prevalence of OP in Chinese postmenopausal females from inception to March 17th, 2022. Two reviewers independently screened the literature, extracted data and evaluated the risk of bias of the included studies. Meta-analysis was then performed using Stata 14.0 software. Results A total of 54 studies involving 96 391 cases and 41 651 confirmed OP patients were included. The meta-analysis results showed that the prevalence of OP in Chinese postmenopausal females was 38.8% (95%CI 34.1% to 43.5%). Subgroup analysis showed that the prevalence of OP was 31.7% (95%CI 16.6% to 48.6%) in females who had been menopausal for less than 5 years, 47.4% (95%CI 32.2% to 62.5%) for 5-9 years, 52.7% (95%CI 37.1% to 68.3%) for 10-14 years, 77.5% (95%CI 69.5% to 85.4%) for 15-19 years, and 78.3% (95%CI 56.3% to 100.0%) for more than 20 years. The rate was 16.2% (95%CI 28.8% to 37.2%) in under 50 years age group, 28.8% (95%CI 34.4% to 47.9%) for 50- years group, 41.1% (95%CI 34.4% to 47.9%) for 60- years group, 55.3% (95%CI 45.8% to 64.8%) for 70- years group, 82.0% (95%CI 76.1% to 87.9%) for 80- years group. The prevalence in different regions was between 31.0% and 43.5%, which was lowest in the northeast (31.0%, 95%CI 26.3% to 51.4%) and highest in the northwest (43.5%, 95%CI 22.3% to 64.7%). According to the year of publication, the rate was 43.9% (95%CI 15.7% to 72.0%) from 1997 to 2009 and 38.2% (95%CI 33.8% to 42.5%) from 2010 to 2021. The prevalence of OP was 24.9% (95%CI 20.5% to 29.3%) in postmenopausal females with no birth or 1 birth, and 45.0% (95%CI 37.0% to 53.0%) in females with 2 or more births. Conclusion The prevalence of OP in Chinese postmenopausal females is relatively high. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
