The moderated mediation model for life satisfaction on symptoms of anxiety in Chinese elderly

Significances were found for the direct effect of life satisfaction on symptoms of anxiety (p = 0.031) (path c) and moderating effect of BMI (p = 0.038) (path d) after adjustment for age, gender, education level, and TONI-4 index scores. However, no significant indirect effect was detected for cognitive function as proposed in our model (b = -0.006, 95% CI [-0.047, 0.044]) (path a*b). The overall moderated mediation model accounting for 23.05% of the variance in scores of HAM-A (F (8, 57) = 2.134, p = 0.047). *Significant at p < 0.05
