Multicultural doula support and obstetric and neonatal outcomes: a multi-centre comparative study in Norway.

Background: Migrant women face an increased risk of poor obstetric and neonatal outcomes. Norway implemented a multicultural doula (MCD) program in 2018, which was designed to improve pregnancy care for this group in vulnerable circumstances. This study aimed to assess the impact of MCD support, provided in addition to standard care, on obstetric and neonatal outcomes for selected newly arrived migrants.

Glycated albumin in pregnancy correlates negatively with body mass index and contributes to the risk of gestational diabetes mellitus.

Objectives: The aims of our study were to establish a reference interval for glycated albumin (GA) in gestational week 30, to investigate whether GA can replace or reduce the need for oral glucose tolerance test (OGTT) in pregnancy, and to reassess the usefulness of body mass-index (BMI), age and fasting glucose in detection of gestational diabetes (GDM).

Design: and methods: We measured GA in 486 healthy pregnant women. Reference interval was calculated using the central 95 % of the results.

Early-life family meal participation and anthropometric measures at 4 years of age.

Early-life family meal participation has been associated with several aspects of nutritional health, but longitudinal associations with linear growth have not yet been investigated. The aim of this study was to investigate whether family meal participation at 12 months of age associates with anthropometric measures 3 years later. We used follow-up data from children born to mothers in the Norwegian Fit for Delivery trial (NFFD) and included 368 first-borns with dietary and anthropometric data at 12 months and 4 years of age.

Employing fasting plasma glucose to safely limit the use of oral glucose tolerance tests in pregnancy: a pooled analysis of four Norwegian studies.

Background/objective: There is no international consensus about the optimal approach to screening and diagnosis of gestational diabetes mellitus (GDM). Fasting plasma glucose (FPG) has been proposed as an alternative universal screening test to simplify the diagnosis of GDM. We investigate the ability of the FPG to predict a 2-hour glucose value below the cut-off for GDM, thereby "ruling out" the necessity of a full OGTT and assess the proportion of GDM-related complications associated with the identified FPG level.

Adverse pregnancy outcomes among women in Norway with gestational diabetes using three diagnostic criteria.

Introduction: The aim of this study was to examine the risk of adverse perinatal outcomes in women diagnosed with GDM by the World Health Organization (WHO) 1999 criteria, and in those retrospectively identified by the Norwegian-2017 and WHO-2013 criteria but not by WHO-1999 criteria. We also examine the effect of maternal overweight/obesity and ethnicity.

Material And Methods: We used pooled data from four Norwegian cohorts (2002-2013), encompassing 2970 mother-child pairs.

Seasonal variation in gestational diabetes mellitus among women in Norway: a national population-based study.

Objectives: Previous research on seasonal variation in the incidence of gestational diabetes mellitus (GDM) has shown inconclusive results. Furthermore, little is known about whether a seasonal variation in GDM might be associated with the maternal country of birth. We examined whether there was seasonal variation in GDM incidence by the maternal country background.

Identifying women with gestational diabetes based on maternal characteristics: an analysis of four Norwegian prospective studies.

Background: There is still no worldwide agreement on the best diagnostic thresholds to define gestational diabetes (GDM) or the optimal approach for identifying women with GDM. Should all pregnant women perform an oral glucose tolerance test (OGTT) or can easily available maternal characteristics, such as age, BMI and ethnicity, indicate which women to test? The aim of this study was to assess the prevalence of GDM by three diagnostic criteria and the predictive accuracy of commonly used risk factors.

Methods: We merged data from four Norwegian cohorts (2002-2013), encompassing 2981 women with complete results from a universally offered OGTT.

Family meal participation is associated with dietary intake among 12-month-olds in Southern Norway.

Background: Family meal participation is associated with healthier eating among children and adolescents. Less is known about family meal participation among infants and toddlers. The objective of the present study was to explore whether family meal participation at 12 months of age is associated with dietary intake and whether a potential relationship differs according to maternal education or child sex.

Impact of maternal education on response to lifestyle interventions to reduce gestational weight gain: individual participant data meta-analysis.

Objectives: To identify if maternal educational attainment is a prognostic factor for gestational weight gain (GWG), and to determine the differential effects of lifestyle interventions (diet based, physical activity based or mixed approach) on GWG, stratified by educational attainment.

Design: Individual participant data meta-analysis using the previously established International Weight Management in Pregnancy (i-WIP) Collaborative Group database (https://iwipgroup.wixsite.

Pre-pregnancy and early pregnancy dietary behavior in relation to maternal and newborn health in the Norwegian Fit for Delivery study - a post hoc observational analysis.

Background: Randomized controlled trials targeting maternal dietary and physical activity behaviors during pregnancy have generally failed to accomplish reductions in the prevalence of adverse maternal and neonatal outcomes. Interventions carried out during pregnancy could thus be missing the mark in maximizing intervention health benefit.

Objective: To investigate whether and dietary behavior as reported at inclusion into the Norwegian Fit for Delivery (NFFD) trial was associated with maternal and neonatal outcomes irrespective of subsequent randomization assignment.

What is the effect of physical activity on duration and mode of delivery? Secondary analysis from the Norwegian Fit for Delivery trial.

Introduction: The beneficial effects of physical activity during pregnancy for the mother and offspring have been reported by several studies but there are conflicting results concerning the possible effect of physical activity on the course of labor and risk of cesarean delivery. This study presents secondary analyses from the Norwegian Fit for Delivery randomized controlled trial, aiming at studying the effect of a lifestyle intervention including group exercise classes, as well as the possible influence of physical activity level in late pregnancy, on labor outcomes.

Material And Methods: Healthy nulliparous women with singleton pregnancy were randomized to an intervention group, n = 303 (dietary counseling and twice-weekly exercise classes) or a control group, n = 303 (standard care).

Preeclampsia and gestational weight gain in the Norwegian Fit for Delivery trial.

Objective: Excessive gestational weight gain is linked to risk of preeclampsia, but it is not clear whether the association is causal. The purpose of this paper was to examine gestational weight gain in the Norwegian Fit for Delivery study among women who developed preeclampsia compared to those who did not, and to further explore associations between weight gain and preeclampsia by including data on body composition (bioimpedance) assessed in the last trimester of pregnancy.

Results: A total of 550 women were eligible for the study.

How does a lifestyle intervention during pregnancy influence perceived barriers to leisure-time physical activity? The Norwegian fit for delivery study, a randomized controlled trial.

Background: To develop effective health promotional and preventive prenatal programs, it is important to understand perceived barriers to leisure-time physical activity during pregnancy, including exercise and sport participation. The aims of the present study was 1) to assess the effect of prenatal lifestyle intervention on the perceived barrier to leisure-time physical activity during pregnancy and the first year after delivery and 2) identify the most important perceived barriers to leisure-time physical activity at multiple time points during and after pregnancy.

Methods: This secondary analysis was part of the Norwegian Fit for Delivery study, a combined lifestyle intervention evaluated in a blinded, randomized controlled trial.

Effect of a prenatal lifestyle intervention on physical activity level in late pregnancy and the first year postpartum.

Background: Despite documented health benefits for mother and baby, physical activity (PA)-level tends to decline in pregnancy. Overweight/obese and physically inactive women are two selected groups at increased risk of pregnancy complications. Thus, efficient strategies to maintain or increase PA-level in pregnancy and the postpartum period, especially among these women, are warranted.

Effects of antenatal diet and physical activity on maternal and fetal outcomes: individual patient data meta-analysis and health economic evaluation.

Background: Diet- and physical activity-based interventions in pregnancy have the potential to alter maternal and child outcomes.

Objectives: To assess whether or not the effects of diet and lifestyle interventions vary in subgroups of women, based on maternal body mass index (BMI), age, parity, Caucasian ethnicity and underlying medical condition(s), by undertaking an individual patient data (IPD) meta-analysis. We also evaluated the association of gestational weight gain (GWG) with adverse pregnancy outcomes and assessed the cost-effectiveness of the interventions.

The effect of a prenatal lifestyle intervention on glucose metabolism: results of the Norwegian Fit for Delivery randomized controlled trial.

Background: The effectiveness of prenatal lifestyle intervention to prevent gestational diabetes and improve maternal glucose metabolism remains to be established. The Norwegian Fit for Delivery (NFFD) randomized, controlled trial studied the effect of a combined lifestyle intervention provided to a general population, and found significantly lower gestational weight gain among intervention participants but no improvement in obstetrical outcomes or the proportion of large infants. The aim of the present study is to examine the effect of the NFFD intervention on glucose metabolism, including an assessment of the subgroups of normal-weight and overweight/obese participants.

Changes in fruit and vegetable consumption habits from pre-pregnancy to early pregnancy among Norwegian women.

Background: A healthy diet is important for pregnancy outcome and the current and future health of woman and child. The aims of the study were to explore the changes from pre-pregnancy to early pregnancy in consumption of fruits and vegetables (FV), and to describe associations with maternal educational level, body mass index (BMI) and age.

Methods: Healthy nulliparous women were included in the Norwegian Fit for Delivery (NFFD) trial from September 2009 to February 2013, recruited from eight antenatal clinics in southern Norway.

Abstract: Sanda B, Vistad I, Haakstad LAH, Berntsen S, Sagedal LR, Lohne-Seiler H, Torstveit MK. Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women.

Background: The International Physical Activity Questionnaire short-form (IPAQ-SF) is frequently used to assess physical activity (PA) level in the general adult population including pregnant women.

Evaluation of implementing a community-based exercise intervention during pregnancy.

Objective: to evaluate the implementation of a community-based exercise intervention (the Norwegian Fit for Delivery study) during pregnancy.

Design: descriptive, explorative.

Setting: healthcare clinics in southern Norway, including urban and rural settings.

Effect of a diet intervention during pregnancy on dietary behavior in the randomized controlled Norwegian Fit for Delivery study.

A mother's diet during pregnancy has the potential to influence both her own and her child's short- and long-term health. This paper reports the effects of a randomized controlled diet intervention during pregnancy on dietary behavior post-intervention as reported in late pregnancy. The diet intervention was part of a lifestyle intervention targeting both diet and physical activity behaviors among nulliparous women participating in the randomized controlled Norwegian Fit for Delivery study (NFFD).

Dietary interventions in overweight and obese pregnant women: a systematic review of the content, delivery, and outcomes of randomized controlled trials.

Context: Interventions targeting maternal obesity are a healthcare and public health priority.

Objective: The objective of this review was to evaluate the adequacy and effectiveness of the methodological designs implemented in dietary intervention trials for obesity in pregnancy.

Data Sources: A systematic review of the literature, consistent with PRISMA guidelines, was performed as part of the International Weight Management in Pregnancy collaboration.

Changes in mode of transportation to work or school from pre-pregnancy to early pregnancy in the Norwegian Fit for Delivery study.

Objective: To describe changes in mode of transportation to work or school from pre-pregnancy to early pregnancy, to describe levels of physical activity related to mode of transportation to work or school, and to examine associations between changes in mode of transportation to work or school and educational level, body mass index (BMI) and age.

Methods: Between September 2009 and February 2013, 575 healthy pregnant nulliparous women were included into the Norwegian Fit for Delivery (NFFD) trial. At inclusion they reported their current and their pre-pregnancy mode of transportation to work or school.

Change in active transportation and weight gain in pregnancy.

Background: Pregnancy is characterised by large weight gain over a short period, and often a notable change in mode of transportation. This makes pregnancy suitable for examining the plausible, but in the scientific literature still unclear, association between active transportation and weight gain. We hypothesize that women continuing an active mode of transportation to work or school from pre- to early pregnancy will have a lower gestational weight gain (GWG) than those who change to a less active mode of transportation.
