目的探索情感平衡在长寿人群健康状况与生活满意度之间的中介效应。方法研究对象为439例来自如皋长寿队列的长寿老人(≥95+岁)。健康状况包括自评健康及客观健康(疾病严重程度);生活满意度采用生活满意度指数A(Life Satisfaction Index A,LSIA)量表测量;情感平衡通过情感平衡量表(Affect Balance Scale,ABS)测量。采用Spearman相关分析和结构方程模型进行分析。结果客观健康、自评健康、情感平衡以及生活满意度两两之间均相关(P均<0.05);客观健康和自评健康对生活满意度的直接效应不显著(β=0.02,P=0.791;β=0.16,P=0.153),客观健康和自评健康通过情感平衡对生活满意度的间接效应显著(β=-0.14,P<0.05;β=0.45,P<0.001)。结论在长寿人群中情感平衡是健康状况与生活满意度之间的中介变量。
Objective To explore the mediating effect of emotional balance between health status and life satisfaction in longevity population. Methods The subjects were 439 longevity elderly (≥95 + years) from the Rugao longevity cohort. Health status included self-rated health and objective health (severity of illness); Life Satisfaction Index was measured by Life Satisfaction Index A (LSIA); Affective Balance was measured by Affect Balance Scale (ABS) measuring. Spearman correlation analysis and structural equation modeling were used for analysis. Results The objective health, self-rated health, emotional balance and life satisfaction were all correlated (P <0.05). The direct effects of objective health and self-rated health on life satisfaction were not significant (β = 0.02, P = 0.791 ; β = 0.16, P = 0.153). The indirect effects of objective health and self-rated health through life balance on emotional satisfaction were significant (β = -0.14, P <0.05; β = 0.45, P <0.001). Conclusion Emotional balance in long-lived population is an intermediate variable between health status and life satisfaction.
