Objective To estimate physical activity (PA) in healthy women before and during pregnancy and to evaluate the features associated with moderate PA (MPA). Methods A prospective cohort study was conducted on women selected 14 weeks of pregnancy during 2013–2015 in primary public health service centers in southern Spain. Type, duration, and frequency of PA (IPAQ questionnaire in first, second, and third trimesters [T1, T2, T3]) were measured. Variables associated with MPA were evaluated using multiple logistic regressions controlling for age, pre‐pregnancy obesity, level of education, number of living children, pre‐pregnancy PA, and adherence to Mediterranean diet (AMD). Results Out of 463 women, MPA was estimated in 64% pre‐pregnancy, and 54%, 61%, and 59% in T1, T2, and T3, respectively. MPA was associated with greater AMD in T2 (adjusted odds ratio [aOR] 1.17, 95% confidence interval [CI] 1.04–1.33) and T3 (aOR 1.16, 95% CI 1.02–1.31), previous PA (aOR 13.5, 95% CI 8.12–22.5 in T1; aOR 2.61, 95% CI 1.72–3.96 in T2; aOR 2.59, 95% CI 1.65–4.05 in T3), and pre‐pregnancy obesity (aOR 2.97, 95% CI 1.28–6.89 in T1; aOR 2.69, 95% CI 1.23–3.60 in T3). Conclusion PA decreased at the beginning of pregnancy, but compliance remained over 50%. MPA was associated with diet, pre‐pregnancy PA, and obesity.

BackgroundThis ecological study aimed i) to quantify the association of age and gender with the three components of pedestrians’ death rates after a pedestrian-vehicle crash: exposure, risk of crash and fatality, and ii) to determine the contribution of each component to differences in death rates according to age and gender in Spain.MethodsWe analyzed data for 220 665 pedestrians involved in road crashes recorded in the Spanish registry of road crashes with victims from 1993 to 2011, and a subset of 39 743 pedestrians involved in clean collisions (in which the pedestrian did not commit an infraction). Using decomposition and quasi-induced exposure methods, we obtained the proportion of increase in death rates for each age and gender group associated with exposure, risk of collision and fatality.ResultsDeath rates increased with age. The main contributor to this increase was fatality, although exposure also increased with age. In contrast, the risk of collision decreased with age. Males had higher death rates than females, especially in the 24–54 year old group. Higher fatality rates in males were the main determinant of this difference, which was also related with a higher risk of collision in males. However, exposure rates were higher in females.ConclusionsThe magnitude and direction of the associations between age and gender and each of the three components of pedestrians’ death rates differed depending on the specific component explored. These differences need to be taken into account in order to prioritize preventive strategies intended to decrease mortality among pedestrians.Electronic supplementary materialThe online version of this article (doi:10.1186/s40621-016-0079-2) contains supplementary material, which is available to authorized users.
