The prospective studies included 16 longitudinal cohort studies (Borodulin et al, 2009;Chasan-Taber et al, 2009;Clarke et al, 2005;Cramp and Bray, 2009;Duncombe et al, 2009;Fell et al, 2009;Goodwin et al, 2000;Hausenblas et al 2008;2011;Lof and Forsum, 2006;Melzer et al, 2009;Owe et al, 2009;Pereira et al, 2007;Poudevigne and Connor, 2005;Sternfeld et al, 1995;Treuth et al, 2005), and 3 cross sectional studies using prospective questions (Hinton et al, 2001;McParlin et al, 2010;Schmidt et al, 2006).…”

“…Few studies have used these or other objective methods to measure activity changes in association before and during pregnancy (Lof and Forsum, 2006) during pregnancy (McParlin et al, 2010;Poudevigne & O'Connor, 2005) and during pregnancy into the post partum (Melzer et al, 2009). One study assessed changes in physical activity pre-pregnancy during and post pregnancy (Treuth et al, 2005).…”

Objectives: to determine the magnitude and type of regular physical activity changes in women around the time of pregnancy. Background: This systematic review synthesizes the results of studies examining regular physical activity in women before they become pregnant and the magnitude and type of changes during pregnancy and the post natal period. Methods:Electronic data bases were searched for relevant articles and PRISMA guidelines for selection of articles were used. Only studies looking at naturally occurring, non intervention changes in regular activity levels were included. The quality assessment was based on protocols of the Cochrane Database of Systematic Reviews. Of the initial 720 titles, 24 studies which met the inclusion criteria of being non intervention studies were included in the final review. Results: Compared to pre pregnancy, the magnitude of physical activity decreased over the course of pregnancy and post natally and the types of activities tended to be of lesser intensity than pre pregnancy. The quality of the research was varied, methodological limitations included using subjective methods of assessment of physical activity (9/24), failing to report reliabilities or validity of measures used (8/24), no information on parity (13/24) or level of fitness prior to pregnancy (11/24). Conclusion: The evidence suggests a marked decrease in the amount and type of moderate to strenuous physical activity during the transition to motherhood, which does not always increase again in the post partum. Patient education targeting specific physical activities at regular intervals during and after pregnancy to improve long term maternal health is necessary.3

Objectives: Human pregnancy is associated with important physiological changes that usually increase energetic requirements. However, great variability exists in the costs and mechanisms required to bear pregnancy. Since body mass (BM) and composition are modified during gestation, it is of great interest to compare the influence of BM on energy expenditure (EE) in pregnant and nonpregnant females.Methods: BM, body composition, and EE of 77 volunteers (35 pregnant and 42 nonpregnant females) were measured. The pregnant volunteers completed two measurement rounds at 28 and 32 gestation weeks. Differences on the measured parameters were sought, and comparison of regression lines was computed to test how BM affected the EE of the volunteers.Results: BM and body composition parameters are significantly higher in pregnant females, but EE is not statistically different. Pregnant females have a larger percentage of fat mass, but lower percentage of fat-free mass (FFM). The EE per kg of FFM is similar in both groups. Comparison of regression lines shows that pregnancy does not change the relationship between BM and EE, but for similar BM pregnant females expend less energy than nonpregnant females. Conclusions: We propose that their larger percentage of passive body tissues is the reason why pregnant females expend less energy than nonpregnant females of similar BM, without changing the scaling of EE on BM. Thus, pregnancy could not be as energetically constraining as usually assumed, with important consequences for human reproductive ecology.

BACKGROUND: Vitamin A has been related to the etiology of congenital diaphragmatic hernia (CDH). We performed a case-control study to investigate whether maternal dietary vitamin A intake is related to CDH in the offspring. METHODS: Thirty-one pregnancies diagnosed with CDH and 46 control pregnancies were included during the study. After CDH diagnosis and inclusion of controls by risk set sampling, maternal vitamin A intake was investigated with a food frequency questionnaire. Serum retinol and retinol-binding protein were determined. Univariable and multivariable logistic regression models were used to calculate risk estimates with adjustment for potential confounders. RESULTS: We found no significant differences in the overall nutrient and vitamin A intake between case and control mothers. After stratification in body mass index (BMI) categories, case mothers with normal weight showed a lower energy adjusted vitamin A intake (685 vs. 843 lg retinol activity equivalents [RAEs] / day; p 5 0.04) and a slightly lower serum retinol (1.58 vs. 1.67 lmol/L; p 5 0.08) than control mothers. Vitamin A intake <800 lg retinol activity equivalents (recommended daily intake) in normal weight mothers was associated with a significantly increased CDH risk (odds ratio [OR], 7.2; 95% confidence interval [CI], 1.5-34.4; p 5 0.01). Associations were not significantly different in underweight and overweight mothers. CONCLUSIONS: In normal-weight mothers, dietary vitamin A intake during pregnancy below the recommended daily intake is significantly associated with an increased risk of a child with CDH. This finding supports the retinoid hypothesis in human CDH, but warrants further investigation in larger study populations. Birth Defects Research (Part A) 97:60-66, 2013. Ó
