- Variation in stillbirth rates across high-income countries and large equity gaps within high-income countries persist. If all high-income countries achieved stillbirth rates equal to the best performing countries, 19,439 late gestation (28 weeks or more) stillbirths could have been avoided in 2015. The proportion of unexplained stillbirths is high and can be addressed through improvements in data collection, investigation, and classification, and with a better understanding of causal pathways. Substandard care contributes to 20-30% of all stillbirths and the contribution is even higher for late gestation intrapartum stillbirths. National perinatal mortality audit programmes need to be implemented in all high-income countries. The need to reduce stigma and fatalism related to stillbirth and to improve bereavement care are also clear, persisting priorities for action. In high-income countries, a woman living under adverse socioeconomic circumstances has twice the risk of having a stillborn child when compared to her more advantaged counterparts. Programmes at community and country level need to improve health in disadvantaged families to address these inequities.

- Vitamin D insufficiency and deficiency have been associated with an increased risk of adverse pregnancy outcomes. Controversy remains as findings have been inconsistent between disparate populations. The aim of this study was to investigate the relationship between vitamin D status and pregnancy outcomes in a large, prospective pregnancy cohort. 25-Hydroxyvitamin D concentration was analysed in serum samples collected at 15 weeks of gestation from 1710 New Zealand women participating in a large, observational study. Associations between vitamin D status and pre-eclampsia, preterm birth, small for gestational age (SGA) and gestational diabetes were investigated. The mean 25-hydroxyvitamin D concentration was 729 nmol/l. In all, 23 % had 25-hydroxyvitamin D concentrations amp;lt; 50 nmol/l, and 5 % of participants had concentrations amp;lt; 25 nmol/l. Women with 25-hydroxyvitamin D concentrations amp;lt; 75 nmol/l at 15 weeks of gestation were more likely to develop gestational diabetes mellitus than those with concentrations amp;gt; 75 nmol/l (OR 23; 95 % CI 11, 51). However, this effect was not significant when adjustments were made for BMI and ethnicity (OR 18; 95 % CI 08, 42). 25-Hydroxyvitamin D concentration at 15 weeks was not associated with development of pre-eclampsia, spontaneous preterm birth or SGA infants. Pregnancy complications were low in this largely vitamin D-replete population.

- BACKGROUND: Presentations for decreased fetal movements comprise a significant proportion of acute antenatal assessments. Decreased fetal movements are associated with increased likelihood of adverse pregnancy outcomes including stillbirth. Consensus-based guidelines recommend pregnant women routinely receive information about fetal movements, but practice is inconsistent, and the information shared is frequently not evidence-based. There are also knowledge gaps about the assessment and management of fetal movement concerns. Women have indicated that they would like more accurate information about what to expect regarding fetal movements.DISCUSSION: Historically, fetal movement information has focussed on movement counts. This is problematic, as the number of fetal movements perceived varies widely between pregnant women, and no set number of movements has been established as a reliable indicator of fetal wellbeing. Of late, maternity care providers have also advised women to observe their baby's movement pattern, and promptly present if they notice a change. However, normal fetal movement patterns are rarely defined. Recently, a body of research has emerged relating to maternal perception of fetal movement features such as strength, presence of hiccups, and diurnal pattern as indicators of fetal wellbeing in addition to frequency.CONCLUSION: Sharing comprehensive and gestation-appropriate information about fetal movements may be more satisfying for women, empowering women to identify for themselves when their baby is doing well, and importantly when additional assessment is needed. We propose a conversational approach to fetal movement information sharing, focusing on fetal movement strength, frequency, circadian pattern, and changes with normal fetal development, tailored to the individual.

- There are limited data on long-term outcomes of mothers or their offspring following exercise interventions during pregnancy. We assessed long-term effects of an exercise intervention (home-based stationary cycling) between 20-36 weeks of gestation on anthropometry and body composition in mothers and offspring after 1 and 7 years. 84 women were randomised to intervention or usual activity, with follow-up data available for 61 mother-child pairs (38 exercisers) at 1 year and 57 (33 exercisers) at 7 years. At 1 year, there were no observed differences in measured outcomes between mothers and offspring in the two groups. At the 7-year follow-up, mothers were mostly similar, except that exercisers had lower systolic blood pressure (-6.2 mmHg; p = 0.049). However, offspring of mothers who exercised during pregnancy had increased total body fat (+3.2%; p = 0.034) and greater abdominal (+4.1% android fat; p = 0.040) and gynoid (+3.5% gynoid fat; p = 0.042) adiposity compared with controls. Exercise interventions beginning during pregnancy may be beneficial to long-term maternal health. However, the initiation of exercise during pregnancy amongst sedentary mothers may be associated with adverse effects in the offspring during childhood. Larger follow-up studies are required to investigate long-term effects of exercise in pregnancy.

Tidskriftsartikel (refereegranskat)abstract
- In secondary analyses of a randomised controlled trial of exercise during pregnancy, we examined associations between mid-pregnancy maternal body mass index (BMI) and excessive gestational weight gain (GWG) with offspring health. Follow-up data were available on 57 mother-child pairs at 1-year and 52 pairs at 7-year follow-ups. Clinical assessments included body composition and fasting blood tests. At age 1 year, increased maternal BMI in mid-gestation was associated with greater weight standard deviation scores (SDS) in the offspring (p = 0.035), with no observed associations for excessive GWG. At age 7 years, greater maternal BMI was associated with increased weight SDS (p < 0.001), BMI SDS (p = 0.005), and total body fat percentage (p = 0.037) in their children. Irrespective of maternal BMI, children born to mothers with excessive GWG had greater abdominal adiposity (p = 0.043) and less favourable lipid profile (lower HDL-C and higher triglycerides). At 7 years, maternal BMI and excessive GWG had compounded adverse associations with offspring adiposity. Compared to offspring of mothers with overweight/obesity plus excessive GWG, children of normal-weight mothers with adequate and excessive GWG were 0.97 and 0.64 SDS lighter (p = 0.002 and p = 0.014, respectively), and 0.98 and 0.63 SDS leaner (p = 0.001 and p = 0.014, respectively). Both greater maternal BMI in mid-pregnancy and excessive GWG were independently associated with increased adiposity in offspring at 7 years.

- Background: We aimed to evaluate metabolic outcomes in overweight/obese nulliparous and multiparous women and their offspring.Study design: Seventy-two overweight and obese women who participated in a randomized controlled trial of exercise in pregnancy were included in the study, comparing 18 nulliparous and 54 multiparous women and their singleton offspring. Women were assessed at 19 and 36 weeks of gestation. Fetal growth was measured using standard obstetric ultrasound techniques. Cord blood was collected at birth. Maternal and offspring body composition was assessed using DXA similar to 2 weeks after delivery.Results: Nulliparous women had higher HbA1c in the third trimester of pregnancy than multiparous women (5.48% vs 5.29%; P=.002) and were more insulin-resistant based on the surrogate marker sex hormone-binding globulin (354 vs 408 nmol/L; P=.047). Nulliparous women also had higher levels of the inflammatory marker tumour necrosis factor-alpha (4.74 vs 3.62 pg/mL; P=.025). At birth, the offspring of nulliparous women were on average 340 g (P=.013) and 0.69 standard deviation scores (P=.026) lighter than those born of multiparous women. Cord blood data showed lower insulin-like growth factor-II (P=.026) and higher IGF binding protein-1 (P=.002) levels in the offspring of nulliparous women. In addition, a less favourable metabolic profile was observed in the offspring of nulliparous women, as indicated by higher triglyceride (P<.001) and interleukin-6 (P=.039) concentrations.Conclusions: Infants born of nulliparous overweight and obese women appear to be exposed to a less favourable metabolic environment in utero, with evidence of subtle adverse metabolic outcomes at birth compared to infants of overweight/obese multiparous women.
