RESUMO
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.

BACKGROUND: There are currently no Irish guidelines on screening for Chlamydia trachomatis infection in pregnancy. Prevalence rates in the antenatal population are not known which has prevented the development of screening recommendations for this group. AIMS: The objective of this study was to determine the prevalence of asymptomatic urogenital C. trachomatis infection in young women attending for care at a large maternity hospital. METHODS: All patients aged 25 years and under attending the Hospital between December 2011 and December 2013 were offered screening for urogenital C. trachomatis infection. Nucleic acid amplification testing of the C. trachomatis cryptic plasmid was performed on either endocervical swabs or first void urine samples. RESULTS: There were 2687 women tested for C. trachomatis infection, 83.4 % (2241/2687) through the antenatal clinics, 7.1 % (193/2687) through the gynaecology clinic, and 9.4 % (253/2687) through the emergency department. The rate of a positive test result was 5.6 % (151/2687) overall. The rates in women ages 16-18, 19-21 and 22-25 years were 9.1 % (31/340), 6.5 % (50/774) and 4.4 % (69/1561), respectively. A positive test result was more likely in those who were unemployed (p = 0.04), those who were Irish (p = 0.03) and those who were unmarried (p < 0.01). There were no cases of neonatal C. trachomatis infection in babies born to mothers who were screened in early pregnancy. CONCLUSIONS: The prevalence rate of detected C. trachomatis infection was 5.6 % in the study population. Screening of antenatal patients may have a role in preventing vertical transmission of infection to the neonate.

BACKGROUND: Diabetes mellitus is a known risk factor for cardiovascular disease which should prompt screening for other cardiovascular risk factors, including dyslipidaemia. Women diagnosed with gestational diabetes mellitus (GDM) are not routinely screened for cardiovascular risk factors. AIMS: The objective of this study was to determine the prevalence of dyslipidaemia postpartum in women with GDM. METHODS: The study was performed in a large university hospital. Women with GDM had a fasting lipid profile performed 6 weeks postnatally. Clinical details were obtained from the medical records. Lipid results in our cohort were compared with healthy women of the same age. RESULTS: The overall prevalence of postpartum dyslipidaemia was 52 % (n = 51). Total cholesterol was raised in 44 % (n = 43), low-density lipoprotein was raised in 33 % (n = 32) and triglycerides were raised in 16 % (n = 16). Of the 51 women with dyslipidaemia, 73 % (n = 37) had more than one abnormality in their lipid profile. Four of the five women with an abnormal postpartum GTT had an abnormal lipid profile. Compared with healthy women of the same age, women with GDM had higher total cholesterol (p = 0.04), higher LDL (p = 0.003), higher triglycerides (p < 0.001) and lower HDL (p < 0.04). CONCLUSIONS: Women with GDM should be screened for dyslipidaemia postpartum and protective cardiovascular interventions offered where appropriate.

BACKGROUND: Maternal diet is critical to fetal development and lifelong health outcomes. In this context, dietary quality indices in pregnancy should be explicitly underpinned by data correlating food intake patterns with nutrient intakes known to be important for gestation. AIMS: Our aim was to assess the correlation between dietary quality scores derived from a novel online dietary assessment tool (DAT) and nutrient intake data derived from the previously validated Willett Food Frequency Questionnaire (WFFQ). METHODS: 524 women completed the validated semi-quantitive WFFQ and online DAT questionnaire in their first trimester. Spearman correlation and Kruskal-Wallis tests were used to test associations between energy-adjusted and energy-unadjusted nutrient intakes derived from the WFFQ, and diet and nutrition scores obtained from the DAT. RESULTS: Positive correlations were observed between respondents' diet and nutrition scores derived from the online DAT, and their folate, vitamin B12, iron, calcium, zinc and iodine intakes/MJ of energy consumed derived from the WFFQ (all P < 0.001). Negative correlations were observed between participants' diet and nutrition scores and their total energy intake (P = 0.02), and their percentage energy from fat, saturated fat, and non-milk extrinsic sugars (NMES) (all P ≤ 0.001). Median dietary fibre, beta carotene, folate, vitamin C and vitamin D intakes derived from the WFFQ, generally increased across quartiles of diet and nutrition score (all P < 0.001). CONCLUSIONS: Scores generated by this web-based DAT correlate with important nutrient intakes in pregnancy, supporting its use in estimating overall dietary quality among obstetric populations.
