New Study: Sitting-time, physical activity, and depressive symptoms in mid-aged women.

| September 9, 2013 | 11 Comments

From the American Journal of Preventive Medicine:

BACKGROUND:

Associations of sitting-time and physical activity with depression are unclear.

PURPOSE:

To examine concurrent and prospective associations between both sitting-time and physical activity with prevalent depressive symptoms in mid-aged Australian women.

METHODS:

Data were from 8950 women, aged 50-55 years in 2001, who completed mail surveys in 2001, 2004, 2007, and 2010. Depressive symptoms were assessed using the Center for Epidemiological Studies Depression questionnaire. Associations between sitting-time (≤4 hours/day, >4-7 hours/day, >7 hours/day) and physical activity (none, some, meeting guidelines) with depressive symptoms (symptoms/no symptoms) were examined in 2011 in concurrent and lagged mixed-effect logistic modeling. Both main effects and interaction models were developed.

RESULTS:

In main effects modeling, women who sat >7 hours/day (OR=1.47, 95% CI=1.29, 1.67) and women who did no physical activity (OR=1.99, 95% CI=1.75, 2.27) were more likely to have depressive symptoms than women who sat ≤4 hours/day and who met physical activity guidelines, respectively. In interaction modeling, the likelihood of depressive symptoms in women who sat >7 hours/day and did no physical activity was triple that of women who sat ≤4 hours/day and met physical activity guidelines (OR 2.96, 95% CI=2.37, 3.69). In prospective main effects and interaction modeling, sitting-time was not associated with depressive symptoms, but women who did no physical activity were more likely than those who met physical activity guidelines to have future depressive symptoms (OR=1.26, 95% CI=1.08, 1.47).

CONCLUSIONS:

Increasing physical activity to a level commensurate with guidelines can alleviate current depression symptoms and prevent future symptoms in mid-aged women. Reducing sitting-time may ameliorate current symptoms.

  5. Hey there would you mind stating which
    blog platform you’re working with? I’m planning to start my

    own blog soon but I’m having a hard time making a decision between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your layout seems different then most blogs and I’m
    looking for something completely unique.
    P.S My apologies for being
    off-topic but I had to ask!

  6. 1 – Term insurance can only be kept for limited periods of time.
    Nice sports cars also happen to be a greater target for theft,
    and your insurance premiums will reflect it.
    This ‘flexibility’ for states has however increased
    design and administrative complexities for insurers.
