Impact of physical function on chronic multimorbidity in elderly adults
Objective To explore the impact of physical function on multimorbidity in the elderly adults.Methods From the China Health and Retirement Longitudinal Study(CHARLS),2 452 elderly adults aged ≥ 60 years from the 2011 baseline survey were selected as the study population and followed up to 2015.The survey included grip strength,short physical performance battery(SPPB),chronic diseases,demographic variables,and health behavior variables.SPSS statistics 26.0 was used for data analysis.Generalized estimating equations were employed to analyze the influencing factors of multimorbidity,and the impact of physical function on multimorbidity was analyzed based on generalized estimating equations after adjusting for confounding factors.Results The preva-lence of multimorbidity among older adults increased from 48.9％(1 199/2 452)in 2013 to 56.1％(1 375/2 452)in 2015,showing an upward trend.The risk of multimorbidity was higher in females(OR=1.287,95％CI 1.124-1.474;P=0.000)and subjects with fall(OR=1.784,95％CI 1.560-2.040;P=0.000)and lower grip strength and lower SPPB scores.The grip strength values were referenced to Q4,and the risks for Q1,Q2,and Q3 were(OR=1.435,95％CI 1.213-1.698;P=0.000),(OR=1.513,95％CI 1.287-1.780;P=0.000)and(OR=1.188,95％CI 1.023-1.379;P=0.024).The SPPB scores were referenced to 10-12 points,and the risks for 0-6 points and 7-9 points were(OR=1.671,95％CI 1.245-2.243;P=0.001)and(OR=1.278,95％CI 1.134-1.440;P=0.000).After controlling for confounding factors,older adults with lower grip strength and lower SPPB scores also have a higher risk of multimorbidity.The risk for grip strength values Q1,Q2 and Q3 were(OR=1.274,95％CI 1.053-1.542;P=0.013),(OR=1.374,95％CI1.151-1.641;P=0.000)and(OR=1.147,95％CI 0.985-1.337;P=0.078);the risk of SPPB scores for 0-6 points and 7-9 points were(OR=1.508,95％CI 1.119-2.033;P=0.007)and(OR=1.220,95％CI 1.081-1.376;P=0.001).Conclusion Physical function is significantly associated with the risk of multimorbidity in the elderly adults,and physical function measures can be used as an effective means of screening for multimorbidity,which is helpful for early identification and targeted prevention and control of individuals at higher risk of multimorbidity.
