Factors influencing successful aging in middle-aged and older adults in developing countries: a meta-analysis

摘要

Background:The successful aging of middle-aged and older adults in developing countries is still in the exploratory stage.This paper aims to understand the current situation of successful aging of middle-aged and older adults in developing countries and systematically evaluate the factors influencing successful aging of middle-aged and older adults in developing countries.Methods:We searched databases including PubMed,Embase,the Cochrane Library,Web of Science,Chinese National Knowledge Infrastructure,CBM,WanFang Data Knowledge Service Platform and VIP from inception to April 30,2021.RevMan 5.3 software was used for meta-analysis.Results:Fourteen studies were included and 17 related risk factors were analyzed.The statistically significant influence factors were gender(odds ratio(OR)=1.37,95%confidenceinterval(CI):1.09~1.71),age>75 years(OR=0.46,95%CI:0.31~0.68),education level(OR=3.24,95%CI:1.84~5.70),Cohabiting with a partner(OR=0.17,95%CI:0.11~0.24),domicile(OR=2.60,95%CI:1.07~6.29),self-rated health(OR=3.15,95%CI:2.33~4.24),income(OR=1.72,95%CI:1.04~2.86),smoking(OR=1.33,95%CI:1.16~1.53),alcohol intake(OR=1.61,95%CI:1.09~2.37),body pain(OR=0.28,95%CI:0.09~0.84),hearing impaired(OR=0.28,95%CI:0.13~0.59),physical exercise(OR=1.46,95%CI:1.24~1.73),eating pattern(OR=1.47,95%CI:1.19~1.80),sleep disorder(OR=0.49,95%CI:0.27~0.89).Sensitivity analysis results show that the results of meta-analysis are stable.Conclusion:Current evidence shows that men living in cities and towns,living with their spouse,good financial status,high educational level,self-rated health,low alcohol consumption,physical exercise and regular diet are beneficial to the successful aging of middle-aged and older adults factor.For ages over 75 years old,five factors,such as long-term smoking,physical pain,hearing impairment and sleep disturbance are the unfavorable factors that hinder successful aging.
