Abstract

AbstractBackground: Physical Activity (PA) during pregnancy has many health benefits, however, inactivity in this populationis common and PA often declines with increasing gestation. PA consultations have been useful in promoting PA in thegeneral population, however their use for addressing PA in pregnancy is unknown. This study aimed to examine if atheory-based intervention using PA consultations would reduce the magnitude of decline in objectively measured PAbetween the first and third trimesters of pregnancy.Methods: A RCT was carried out in an urban maternity unit in Northern Ireland between September 2012 and June2013. 109 low-risk, primigravida pregnant women were randomised to a control (n = 54) or intervention group (n = 55).Intervention participants received three face-to-face individual PA consultations. Daily PA was measured in eachtrimester using seven day accelerometry. The study was approved by a NHS trust (12/NI/0036). PA data incounts per minute (CPM) were categorised into intensity using Freedson cut points and mean minutes of PAwere compared between groups using repeated measures ANOVA with a sub-analysis stratifying participantsper PA level in trimester one.Results: Intention to treat analysis was performed on data from 97 participants. Time in moderate, vigorousand moderate-vigorous intensity PA (MVPA) significantly declined between trimesters one and three in bothgroups (P < 0.001). There were no statistically significant differences in PA between groups in any trimester.Women in the intervention group who were less active in trimester one did not demonstrate a significantdecline in MVPA throughout pregnancy (in contrast with the decline identified in the more active participants).Conclusions: The findings indicate that PA consultations were not effective in reducing the decline of MVPA inthroughout pregnancy, however, women who were less active in trimester one and received PA consultationshad a lesser decrease in MVPA. It is possible that pregnant women, specifically those who are more active atthe start of pregnancy, have differing needs for PA behaviour change and maintenance, requiring more intenseinterventions than less active women.Trial Registration: Current Controlled Trials Register ISRCTN61829137.Keywords: Physical activity, Pregnancy, Decline, Patterns, RCT, Intervention
