Abstract

<p>The purpose of this study was to clarify the direct and indirect effects of cognitive factors (economic satisfaction: ES, mental and emotional well-being: MEWB) and dietary diversity (DD) on self-rated health (SH) of men and women separately among healthy elderly aged >65 years living in A municipality in Okinawa. A total of 1,525 respondents excluding long-term care needs participants were examined at the baseline. DD was characterized by a combination of dishes, i.e. staple, main dishes, sub-dishes, milk and dairy product, and fruits. When the fit of hypothetical models was evaluated using covariance structure analysis, models showing indirect effects mediated by MEWB and by DD were statistically more acceptable (CFI=0.963, NFI=0.944, RMSEA=0.034) , in comparison with the direct effects of ES on SH in models for both men and women. When a more comprehensive examination was performed by integration of direct with indirect effects, the effect of MEWB on SH was larger in women, and that of ES was larger in men. The present findings suggest that creating support for MEWB based on income support might enhance the SH of healthy elderly people through improvement of DD.</p>
