It can be concluded that physical activity may be effective in reducing burn-out risk .
The few observational studies linking sedentary and dietary behavior with burn-out risk suggest that being more sedentary and eating less healthy are each associated with higher burn-out risk .
Although it is believed that physical activity , sedentary , and dietary behavior ( i.e. , energy balance-related behavior ) may decrease the risk of burn-out  , the association between both is currently not well understood .
Therefore , the aim of this systematic review was to synthesize studies investigating the relationship between energy balance-related behavior  and  burn-out risk .
Relation between clinical depression risk and physical activity and time spent watching television in older women: a 10-year prospective follow-up study.
Although  physical activity ( PA ) has been inversely associated with depressive symptoms , it is not clear whether regular PA and television watching are associated with clinical depression risk . The authors conducted a prospect i ve analysis involving 49,821 US women from the Nurses ' Health Study who were free from depressive symptoms at baseline ( 1996 ) . Information on PA was obtained from vali date d question naires completed in 1992 , 1994 , 1996 , 1998 , and 2000 ; analyses were conducted using the cumulative average of PA ( minutes/day ) with a 2-year latency period applied . Participants were asked about television-watching habits in 1992 . Cox proportional hazards regression models adjusted for multiple risk factors were used to estimate relative risks of clinical depression ( self-reported physician-diagnosed depression or use of antidepressants ) . During 10 years of follow-up ( 1996 - 2006 ) , 6,505 incident cases of depression were documented . Higher  levels of PA  were associated with lower depression risk . The multivariate relative risk comparing the highest level of PA  ( ≥ 90 minutes/day ) with the lowest ( < 10 minutes/day ) was 0.80 ( 95 % confidence interval : 0.70 , 0.92 ; P(trend ) < 0.001 ) . In contrast , the risk of depression increased with increasing television-watching time . The multivariate relative risk comparing women who spent 21 hours/week or more watching television with those who spent 0 - 1 hour/week was 1.13 ( 95 % confidence interval : 1.00 , 1.27 ; P(trend ) = 0.01 ) . Analyses simultaneously  considering PA and television watching suggested that both contributed independently to depression risk
