Predictors of physical activity at 12 month follow-up after a supervised exercise intervention in postmenopausal women

Abstract

BackgroundFew studies have examined recreational physical activity (RPA) after participating in a structured exercise intervention. More specifically, little is known about the long-term effects of exercise interventions in post-menopausal women. This study had two objectives: 1) To compare RPA in postmenopausal women in the exercise group and the control group 12 months after the end of the Alberta Physical Activity and Breast Cancer Prevention (ALPHA) Trial; and 2) To apply the Theory of Planned Behaviour (TPB) to identify predictors of RPA 12 months post-intervention among women in the exercise group.MethodsSelf-reported RPA 12-months post-intervention from a validated questionnaire was used to estimate RPA levels for control group (118/160, 74% response) and exercise group participants (126/160, 79% response). Bivariate analysis was used to compare RPA between exercise and control group participants and to identify TPB variables for multivariate analysis. Logistic regression was applied to TPB data collected from self- administered questionnaires at end of trial by exercise group participants (126/160, 79% response) to identify predictors of long-term RPA.ResultsAt 12 months post-intervention, 62% of women in the exercise group were active compared to 58% of controls (p = 0.52). Of the TPB constructs examined, self-efficacy (OR =2.98 (1.08-8.20)) and behavioural beliefs (OR = 1.46 (1.03-2.06)) were identified as predictors of RPA for exercise group participants.ConclusionsLevels of RPA in the exercise and control groups were comparable 12 months post intervention, indicating that participation in the ALPHA trial was associated with increased physical activity in previously inactive women, regardless of randomization into either the exercise group or in the control group. Exercise interventions that promote self-efficacy and positive behavioural beliefs have the potential to have long-term impacts on physical activity behaviour, although further research is needed to examine additional psychological, social and environmental predictors of long-term RPA in post-menopausal women.Trial registrationClinicalTrials.gov NCT00522262.Electronic supplementary materialThe online version of this article (doi:10.1186/s12966-015-0219-z) contains supplementary material, which is available to authorized users.

The Effect of Yoga on Women’s Premenstrual Syndrome: A Randomized Controlled Clinical Trial

“…The purpose of this article is to address effects of war and poverty on the health of reproduction of women and to offer scientific contribution and solutions. With considering: (a) the positive effects of physical exercises on global women's health (14)(15)(16), (b) the negative attitudes of the Iranian society towards women's sports (17), (c) the low percentage (0.3%) of participation of women in sports in East Azerbaijan, Iran (18,19), (d) lack of any kind of study from Iran on PMS and yoga, and (e) the effects of culture on PMS (20), the current investigation was designed to study the effects of yoga on women with PMS in reproductive age, in Tabriz society.…”

“…Physical activity also reduces the risks associated with cardiovascular disease and diabetes mellitus [3] . Current public health guidelines recommend 150 minutes per week of moderate intensity or 75 minutes per week of vigorous intensity aerobic physical activity for adults in order to obtain health benefits [4] .
