Caffeine Intake throughout Pregnancy, and Factors Associated with Non-Compliance with Recommendations: A Cohort Study.

Maternal caffeine consumption is associated with adverse gestational outcomes. The aim of this study was to assess the intake of caffeine and factors associated with the non-adherence to caffeine intake recommendations in a cohort of 463 women before (T0) and in each trimester of gestation (T1, T2, and T3), by using validated questionnaires. Caffeine intake (median (mg/day), IQR) was 100.0 (181.1) at T0, 9.42 (66.2) at T1, 12.5 (65.6) at T2, and 14.0 (61.1) at T3 (p < 0.001). Non-compliance prevalence (intake > 200 mg/day) was 6.2% at T1, 4.2% at T2, and 2.7% at T3. Not being an active smoker at T1 (OR = 0.17; 95% CI 0.05−0.59) and T2 (OR = 0.22; 95% CI 0.09−0.52), adherence to the Mediterranean Diet at T1 (OR = 0.50; 95% CI 0.28−0.88) and T2 (OR = 0.39; 95% CI 0.15−1.02), and moderate physical activity at T1 (OR = 0.50; 95% CI 0.28−0.88) were inversely associated with caffeine consumption. Although caffeine intake may be considered low, intake prevalence increases throughout pregnancy. Although the main source of caffeine during pregnancy is coffee, attention must be also paid to the increasingly intake of chocolate, of which the effect during pregnancy is controversial. Smoking, non-adherence to a good quality diet, and light physical activity are associated with a higher caffeine intake and a lower compliance with caffeine intake recommendations. Perinatal dietary and lifestyle educational policies are needed.

Variations in Author Gender in Obstetrics Disease Prevalence Literature: A Systematic Review.

This systematic review aims to evaluate gender differences in authorship of prevalence literature concerning intimate partner violence (IPV) during pregnancy and gestational diabetes mellitus (GDM). GDM studies were matched for publication year and study country as a gender-neutral obstetric disease with similar morbidity to IPV. Relevant studies were captured without language restrictions via online searches of PubMed, Scopus and Web of Science from database inception to January 2022. Proportion of female authors and gender of the first and corresponding author were outcome measures. Multivariable regression models were built to examine if female authors featured more or less often in IPV during pregnancy and GDM literature adjusting by the influence of type of study, country's human development index (HDI), year of publication and journal's impact factor. 137 IPV-GDM studies pairs were included. Female authors in IPV studies were slightly lower than in GDM [59.7%, 95% CI 54.7-64.7, vs. 54.9%, 95% CI 50.7-59.1, p = 0.204]. Studies published in high-income countries were more likely to be signed by a woman as first and corresponding author (Odds Ratio 2.22, 95% CI 1.20; 4.11, p = 0.011 and Odds Ratio 2.24, CI 1.22; 4.10, p = 0.009 respectively) and proportion of women as corresponding authors decreased as the journal impact factor increased (ß = 0.62, 95% CI 0.37, 1.05, p = 0.075). There is a gender gap in the field of prevalence research in IPV during pregnancy with variations according to the level of development. International programs aimed at eradicating these inequalities are needed.

Physical activity before and during pregnancy: A cohort study.

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.
