BACKGROUND: Physical activity (PA) has a positive association with @entity283 ( @entity283 ) in the general population. The association between PA and @entity283 in those with poor mental health is less clear. PURPOSE: To examine the concurrent and prospective dose-response relationships between total PA ( @entity865 ) and walking only with @entity283 in @entity1 aged 50-55 years with @entity308 symptoms in 2001. METHODS: @entity1 were 1,904 @entity1 born in 1946-1951 who completed mailed surveys for the Australian Longitudinal Study on @entity1 's Health in 2001, 2004, 2007, and 2010, and reported @entity308 symptoms in 2001. At each time point, they reported their weekly minutes of walking, moderate PA, and vigorous PA. A summary @entity865 score was created that accounted for differences in energy expenditure among the three PA types. Mixed models were used to examine associations between @entity865 and @entity283 (short form-36 [SF-36] component and subscale scores) and between walking and @entity283 , for @entity1 who reported walking as their only PA. Analyses were conducted in 2013-2014. RESULTS: Concurrently, higher levels of @entity865 and walking were associated with better @entity283 (p<0.05). The strongest associations were found for physical functioning, vitality, and social functioning subscales. In prospective models, associations were attenuated, yet compared with @entity1 doing no @entity865 or walking, @entity1 doing "sufficient" @entity865 or walking had significantly better @entity283 over time for most SF-36 scales. CONCLUSIONS: This study extends previous work by demonstrating trends between both @entity865 and walking and @entity283 in @entity1 reporting @entity308 symptoms.
