A latest study has found that people with high fitness during their middle ages are significantly less likely to die from heart diseases in later life even if they were diagnosed with depression.
The researchers said the reasons behind this may partly be connected to the general health effects of physical activity, including the fact that exercise decreases inflammation that may cause depression. By reducing inflammation, the risk for depression and heart diseases are lowered, the researchers mentioned.
For the study, the researchers examined database of nearly 18,000 participants who had their cardio-respiratory fitness measured at an average age of 50 years.
The researchers used Medicare Administrative data to establish correlations between the participants’ fitness at midlife to rates of depression and heart diseases in older age.
