Peeters G, Burton N & Brown W. Associations between sitting time and a range of symptoms in mid-age women. Preventive Medicine, 2013; 56(2): 135-141

Objective:The aim of this study was to explore longitudinal associations between sitting and physical and psychological symptoms in mid-age women.Method: Mid-age (53-58years) participants in the Australian Longitudinal Study on Women's Health completed mail surveys in 2004 (n=10,286), 2007 (n=10,128) and 2010 (n=9452) with questions about sitting time (<6, 6-9, and =9h/day) and frequency of 19 symptoms in the preceding 12months (often vs. never/rarely/sometimes). Associations between sitting and symptoms were examined using two logistic generalized estimating equations models: (a) sequential cross-sectional data from 3 surveys, and (b) prospective model with a 3-year time lag (significance level=0.01).Results: Approximately 53%, 30% and 17% of the women were classified as sitting <6, 6-9 and =9h/day in 2004. In adjusted cross-sectional models, women sitting =9h/day had significantly higher odds of breathing difficulties (OR=1.52, 99% CI=1.17-2.00), tiredness (OR=1.21, CI=1.05-1.40), bowel problems (OR=1.26, CI=1.02-1.56), eyesight problems (OR=1.16, CI=1.01-1.34), and depression (OR=1.39, CI=1.15-1.68) than women sitting <6h/day. Adjusted prospective models showed higher odds of breathing difficulties (OR=1.94, CI=1.40-2.69), chest pain (OR=2.04, CI=1.14-3.70), and tiredness (OR=1.24, CI=1.04-1.48). Associations with breathing difficulties and chest pain remained significant after excluding participants with chronic conditions in 2004.Conclusion: Prolonged sitting may a determinant of breathing difficulties and chest pain three years later in mid-age women.
