Symptoms of depression are associated with physical inactivity but not modified by gender or the presence of a cardiovascular disease; a cross-sectional study

Abstract

Abstract Background Depressive symptomatology may act as a barrier to enhance physical activity. This phenomenon is predominantly found in patients with an established cardiovascular disease (CVD) and in female patients. This cross-sectional study investigated (1) the association between symptoms of depression and physical inactivity, and (2) whether this association is different between primary and secondary prevention patients, and between men and women. Methods The study design concerns a secondary analysis of baseline data from a randomized clinical trial, including primary and secondary prevention patients (n = 2184; mean age 71.6 ± 8.94), from 34 general practitioner panels. The Rapid Assessment of Physical Activity questionnaire (RAPA) was used to measure patient reported activity levels. Symptoms of depression were determined using the Patient Health Questionnaire (PHQ-9). Multilevel linear regression analysis was used to explore the association between symptoms of depression and physical activity while adjusting for confounders. Gender and whether or not having a CVD were considered as potential effect modifiers for the association between symptoms of depression and inactivity. Results Symptoms of depression were associated with lower levels of physical activity. This association was neither different for men and women nor for primary and secondary prevention patients. Conclusion In primary care patients’ symptoms of depression were associated with physical inactivity. This association was not modified by gender or the presence of a CVD. Future research should focus on lifestyle interventions aiming at the increase of physical activity levels, while emphasizing on improving symptoms of depression in men, women, and patients both with and without a history of CVD.
