RESUMEN
BACKGROUND: This longitudinal study examined the profile and pregnancy-related behaviours of women who reported smoking in two successive pregnancies when they presented for prenatal care in a large maternity hospital. METHODS: Using the hospital electronic medical records, women who delivered two successive singleton pregnancies during the years 2011-15 were analyzed. Standardized data were computerized by a midwife at the first prenatal visit, following delivery and before discharge. RESULTS: Over the 5 years, 6647 women delivered twice. Overall 5754 (86.6%) were persistent non-smokers in both pregnancies, 609 (9.2%) were persistent smokers in both pregnancies and between pregnancies 202 (3.0%) quit and 82 (1.2%) started smoking. Compared with persistent non-smokers, persistent smokers had higher rates of reported illicit drug use, alcohol consumption and psychological problems and lower rates of planned pregnancy, folic acid supplementation and breastfeeding in both pregnancies (all P < 0.001). In persistent smokers, folic acid supplementation practices deteriorated and illicit drug use increased in the subsequent pregnancy. CONCLUSIONS: We found that approximately one in 10 women smoked in two consecutive pregnancies. Furthermore, compared with non-smokers, persistent smokers were more likely to report other health behaviours associated with adverse pregnancy outcomes and may require additional multidisciplinary support.

BACKGROUND: Maternal nutrition is a determinant of pregnancy outcomes. Few studies have evaluated the potential of online nutrition resources to modify behaviour. This randomized controlled trial aimed to determine whether access to a customized evidence-based nutrition website in pregnancy improved neonatal outcomes. METHODS: Women <18 weeks gestation were recruited at their convenience. The control group received standard care. In addition to standard care, the intervention group received access to an evidence-based nutrition website, customized to the preferences of pregnant women. RESULTS: Of the 250 women, there were no differences in characteristics between the two groups. Of the women, 91.0% reported they make a conscious effort currently to eat a healthy diet. However, only 19.6% met dietary requirements for calcium, 13.2% for iron, 2.7% for folate and 2.3% for iodine. The most popular website section was pregnancy nutrition advice but engagement was not sustained. Access to the website was not associated with any improvement in clinical outcomes (P > 0.05). CONCLUSIONS: We found that provision of a customized website providing nutrition information, did not improve neonatal outcomes. Future studies should explore whether redesign with website interactivity or embedding information on popular digital platforms sustains women's engagement and modifies dietary behaviour.

Background: The World Health Organization recommends that women take 400 µg of folate supplementation daily throughout pregnancy. We examined the relationship between total folate intake from the diet and supplements at the first prenatal visit and haematological indices at this visit and subsequently. Methods: Women were recruited at their convenience and in addition to clinical and sociodemographic details, detailed questionnaires on dietary intakes and supplementation consumption were completed under supervision. A full blood count and serum and red blood cell (RBC) folate levels were taken. Results: Of the 502 women studied, 97.5% had inadequate total dietary folate intake at the first visit, but, 98.2% were taking folic acid (FA) supplementation. Only 1.8% (n = 9) had anaemia at their first visit (with no case of macrocytosis). Subsequently, 212 women had a further Hb sample in the third trimester and 8.5% (n = 18) were anaemic and 43.4% (89/205) were anaemic postnatally. There was a relationship between the development of anaemia postnatally and lower RBC folate levels at the first visit (P = 0.02). Conclusions: In a country where FA food fortification remains voluntary, these findings support the recommendation that women should start FA supplementation before pregnancy and continue FA after the first trimester.

Background: Maternal nutrition intakes may influence neonatal birthweight and adiposity; however, inconsistencies within the literature exist. The relationships between maternal dietary intakes in early pregnancy and both birthweight and neonatal adiposity requires elucidation. This study examined the relationship between early pregnancy dietary intakes and subsequent birthweight and neonatal adiposity. Methods: Women were recruited at their convenience after sonographic confirmation of a singleton pregnancy. Women completed a Willet food frequency questionnaire evaluating habitual food and nutrient intakes at their first antenatal visit. Neonatal body composition was measured using air-displacement plethysmography. Results: Of the 385 mother-neonate dyads, mean maternal age was 30.8 ± 5.3 years, mean Body Mass Index (BMI) was 24.5 ± 4.8 kg/m2 and 41.8% (n = 161) were nulliparous. There were no relationships between maternal food intakes and birthweight (P > 0.05) (n = 385). On multivariable analysis there was a positive relationship between polyunsaturated fat and neonatal fat mass index (FMI) (beta = 0.015, 95% CI = 0.002-0.028, P = 0.04) (n = 80). Conclusion: Dietary intakes of polyunsaturated fat in early pregnancy are positively associated with neonatal FMI at birth on multivariable analysis. Further longitudinal studies need to explore this association and the long-term implications for the neonate.

Aims Screening for gestational diabetes mellitus (GDM) may be universal or selective based on risk factors. We audited selective screening with an Oral Glucose Tolerance Test (OGTT). Methods Clinical and laboratory details of the first 200 women who delivered a baby in 2017 were analysed. Results Based on national recommendations, 46.5% (n=93) had maternal risk factors (RF) and an additional 6.5% (n=13) had fetal RF. Nine women with RF, for unexplained reasons did not have their OGTT. Of the 95 who had their OGTT, the diagnosis of GDM was made in 27.4% (n=26). The diagnosis of GDM was made in an additional 8 women outside selective screening giving an overall incidence of 17.0%. Discussion More than half of the women needed to be screened selectively for GDM. Compliance with the national recommendations was incomplete and thus the diagnosis of GDM may be missed even in an academic setting.
RESUMEN
OBJECTIVES: During pregnancy, women are increasingly turning to web-based resources for information. This study examined the use of web-based nutritional information by women during pregnancy and explored their preferences. STUDY DESIGN: Cross-sectional observational study. METHODS: Women were enrolled at their convenience from a large maternity hospital. Clinical and sociodemographic details were collected and women's use of web-based resources was assessed using a detailed questionnaire. RESULTS: Of the 101 women, 41.6% were nulliparous and the mean age was 33.1 years (19-47 years). All women had internet access and only 3% did not own a smartphone. Women derived pregnancy-related nutritional information from a range of online resources, most commonly: What to Expect When You're Expecting (15.1%), Babycenter (12.9%), and Eumom (9.7%). However, 24.7% reported using Google searches. There was minimal use of publically funded or academically supported resources. The features women wanted in a web-based application were recipes (88%), exercise advice (71%), personalized dietary feedback (37%), social features (35%), videos (24%) and cooking demonstrations (23%). CONCLUSIONS: This survey highlights the risk that pregnant women may get nutritional information from online resources which are not evidence-based. It also identifies features that women want from a web-based nutritional resource.
