Abstract:
Objective:To estimate the prevalence of depressive symptoms in community-dwelling elderly with mild cognitive impairment(MCI) in China by systemic review.Methods:PubMed, Web of Science, CNKI, VIP database and other databases were searched for cross-sectional studies on the prevalence of depressive symptoms in the elderly with MCI in China. The search period was from January 1, 2011 to October 1, 2021. The studies were screened according to predefined inclusion and exclusion criteria. Stata 12.0 software was used for statistical analysis, and finally the prevalence rate of depressive symptoms in the elderly with MCI in China was calculated.Results:A total of 2 036 relevant studies were retrieved, among which 14 met the inclusion criteria, involving 3 819 cases. Meta-analysis showed that 32.3%(30.9%-33.7%) of community-dwelling elderly with MCI had depressive symptoms. Subgroup analysis showed that the detection rate of depressive symptoms in studies published during 2016—2021 was higher than that during 2011—2015 (34.6% vs. 23.5%, χ2=11.64, P<0.001).However there were no significant differences in detection rate between genders, among studies using different depression assessment and MCI assessment tools, and among different geographic regions (all P>0.05). Conclusion:The study shows that the prevalence of depressive symptoms in community-dwelling elderly with MCI in China is high and it presents a rising trend, suggesting that attention should be paid to mental health of elderly in the community and the screening of depressive symptoms should be strengthened for those with MCI.
