Small numbers of pregnant women adhere to physical activity (PA) guidelines. Theoretically informed intervention may alter PA. Therefore, this research aimed to explore the effect of a theory-based (Health Action Process Approach, HAPA) intervention in reducing the magnitude of decline in PA during pregnancy. 109 primiparous, low risk women (mean age 29.9 +/-4.8 years) took part in an RCT in an urban maternity unit. Women were randomised to either usual care group or to intervention group, who received three individual PA consultations and an invitation to attend a weekly walking group after 20 weeks gestation. The primary outcome, change In PA, and secondary outcomes; mood, self-esteem, anxiety, social support, quality of life, perceived health, health service use, HAPA variables, gestational weight gain (GWG) and obstetric delivery outcomes were measured at weeks 10-14, 20-22 and 36-38 gestation. Ethical approval was granted by the Office for Research Ethics Committee, Northern Ireland (12/NI/0036) and the trial was registered (ISRCTN61829137). PA changes were analysed using Two-way Analysis of Variance (ANOVA) and Wilcoxon signed-rank tests. Changes in secondary outcomes were analysed using Repeated Measures ANOVA or chi square tests. Minutes of Moderate , and Vigorous intensity PA (MVPA) significantly decreased over pregnancy in both groups, however, the intervention group demonstrated a lesser decline with a median decrease of 3.5 minutes per day compared to six in the control group. Those attending at least one walking group (N=13) indicated a trend towards a lesser decrease in MVPA (attenders two and non-attenders four minutes per day). The intervention group showed greater increases in positive mood and less increase in anxiety (mood 2.4 vs 1.2; anxiety 1.9 vs 2.4). There were no differences in obstetric outcomes between groups. Results suggest that the intervention can reduce the decline in PA during pregnancy, however further testing is recommended.
