BackgroundPublished guidelines emphasise the need for early antenatal care to promote maternal and neonatal health. Inadequate engagement with antenatal care is associated with adverse pregnancy outcomes including maternal death. The factors that influence the uptake and utilisation of maternity care services are poorly understood. We retrospectively explore a large maternity database of births in a large referral UK hospital to capture the socio-demographic factors that influence late pregnancy booking, and then prospectively compare the stress and social support status of consenting early and late-booking women.MethodsRetrospective socio-demographic and clinical outcome data on 59,487 women were collected from the maternity database record of births between 2002 and 2010 at the Jessop Wing Hospital, Sheffield UK. In a follow-on prospective survey between October 2012 and May 2013 a convenience cohort of early and late bookers for antenatal care were then studied using validated scales for fetomaternal attachment, stress and anxiety, and social support.ResultsIn our retrospective study, pregnancy during the teenage years, higher parity, non-white ethnic background, unemployment and smoking were significantly associated with late access to antenatal services and poor fetal outcomes (P < 0.001). However, late booking per se did not predict adverse fetal outcomes, when socio-demographic factors were accounted for. A high index of multiple deprivation (IMD) score remained independently associated with late booking when confounding factors such as ethnicity and employment status were controlled for in the model (P = 0.03). Our prospective data demonstrated that women who book late were more likely to be unmarried (OR: 3.571, 95 % CI: 1.464–8.196, p = 0.005), of high parity (OR: 1.759, 95 % CI: 1.154–2.684, P = 0.009), and have lower social support than early bookers (P = 0.047).ConclusionsOf the many complex sociocultural factors that influence the timing of maternal engagement with antenatal care, multiple deprivation and poor social support remain key factors. Improving access to prenatal care requires in-depth exploration of the relationship between maternal psychosocial health indices, social support mechanisms and engagement with antenatal care. Findings from these studies should inform interventions aimed at improving access to care.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-015-0753-3) contains supplementary material, which is available to authorized users.
Maternal smoking leads to reversible changes in FHR variability that mimic those associated with an increased incidence of adverse cardiovascular events in adults. As heart rate and variability reflect the autonomic control of the heart, our findings suggest that maternal smoking interferes with the autonomic control of the FHR.
ObjectiveTo assess the influence of gender, time of the day and gestational age on fetal heart rate (FHR) parameters between appropriate-for-gestational-age (AGA) and small-for-gestational age (SGA) fetuses using a portable fetal ECG monitor employed in the home setting.MethodsWe analysed and compared the antenatal FHR data collected in the home setting on 61 healthy pregnant women with singleton pregnancies from 24 weeks gestation. Of the 61 women, 31 had SGA fetuses (estimated fetal weight below the tenth gestational centile) and 30 were pregnant with AGA fetuses. FHR recordings were collected for up to 20 h. Two 90 min intervals were deliberately chosen retrospectively with respect to signal recording quality, one during day-time and one at night-time for comparison.ResultsOverall, success rate of the fetal abdominal ECG in the AGA fetuses was 75.7% compared to 48.6% in the SGA group. Based on randomly selected episodes of heart rate traces where recording quality exceeded 80% we were able to show a marginal difference between day and night-time recordings in AGA vs. SGA fetuses beyond 32 weeks of gestation. A selection bias in terms of covering different representation periods of fetal behavioural states cannot be excluded. In contrast to previous studies, we neither controlled maternal diet and activity nor measured maternal blood hormone and heart rate as all mothers were monitored in the home environment.ConclusionBased on clinically unremarkable, but statistically significant differences in the FHR parameters between the AGA and SGA group we suggest that further studies with large sample size are required to assess the clinical value of antenatal fetal ECG monitoring.
