Multicentre double-blind randomised placebo-controlled four-arm trial to assess the effect of oral sodium bicarbonate and intravenous hyoscine butylbromide on spontaneous delivery after induction of labour in nulliparous women: protocol for the Safe Induction of Labour Trial (SAINT).

Introduction: Presently, more than one in four births in high-income countries undergo labour induction. Induction of labour is an independent risk factor for adverse obstetric outcomes, including high rates of operative delivery. Two drugs, hyoscine butylbromide and sodium bicarbonate, have been used in labour to facilitate cervical dilation and prevent uterine lactate accumulation.

Navigating weight, risk and lifestyle conversations in maternity care: a qualitative study among pregnant women with obesity.

Background: Pregnant women with obesity face heightened focus on weight during pregnancy due to greater risk of medical complications. Closer follow-up in maternety care may contribute to reduce risk and promote health in these women. The aim of this study was to gain a deeper insight in how pregnant women with obesity experience encounters with healthcare providers in maternity care.

Weight development from childhood to motherhood-embodied experiences in women with pre-pregnancy obesity: a qualitative study.

Background: Pre-pregnancy obesity increases the risk of perinatal complications. Post-pregnancy is a time of preparation for the next pregnancy and lifestyle advice in antenatal care and postpartum follow-up is therefore recommended. However, behavioral changes are difficult to achieve, and a better understanding of pregnant women's perspectives and experiences of pre-pregnancy weight development is crucial.

Feasibility of a Postpartum Web- and Phone-Based Lifestyle Program for Women with a History of Preeclampsia or Gestational Diabetes: A Pilot Intervention Study.

Background: Women with a history of preeclampsia (PE) or gestational diabetes mellitus (GDM) are at increased risk of diabetes and cardiovascular disease (CVD) later in life. Increased awareness of pregnancy complications as early warning signs for CVD has called for postpartum primordial prevention strategies. The aim of this study was to evaluate the feasibility of a postpartum web- and phone-based lifestyle program promoting healthy lifestyle behaviors to women after a pregnancy complicated by PE or GDM.

Experiences of childbirth care among immigrant and non-immigrant women: a cross-sectional questionnaire study from a hospital in Norway.

Background: Immigrant women have higher risks for poor pregnancy outcomes and unsatisfactory birth experiences than the general population. The mechanisms behind these associations remain largely unknown, but they may result from differential care provided to immigrant women or unsatisfactory interactions with health providers. This study aimed to investigate immigrant and non-immigrant women's experiences of health care during childbirth, particularly assessing two dimensions: perceived general quality of care and attainment of health care needs during childbirth.

Adverse childhood experiences and pre-pregnancy body mass index in the HUNT study: A population-based cohort study.

Objective: Investigate the association between adverse childhood experiences and pre-pregnancy body mass index (BMI) in a population-based cohort in Trøndelag county, Norway.

Materials And Methods: We linked data from the third (2006-2008) or fourth (2017-2019) survey of the Trøndelag Health Study (HUNT) and the Medical Birth Registry of Norway for 6679 women. Multiple logistic regression models were used to examine the association between adverse childhood experiences and pre-pregnancy BMI.

Do parental heights influence pregnancy length?: A population-based prospective study, HUNT 2.

Background: The objective of this study was to examine the association of maternal and paternal height with pregnancy length, and with the risk of pre- and post-term birth. In addition we aimed to study whether cardiovascular risk factors could explain possible associations.

Methods: Parents who participated in the Nord-Trøndelag Health Study (HUNT 2; 1995-1997) were linked to offspring data from the Medical Birth Registry of Norway (1997-2005).

Offspring birth weight and cardiovascular risk in parents: a population-based HUNT 2 study.

Low birth weight is associated with increased risk of cardiovascular disease and type 2 diabetes in later life. The fetal insulin hypothesis suggests that shared genetic factors partly explain this association. If fetal genes predispose to both low birth weight and cardiovascular disease in adulthood, fathers of offspring with low birth weight should display an unfavorable profile of cardiovascular risk factors.

Cardiovascular risk factors prior to conception and the length of pregnancy: population-based cohort study.

Objective: To study the association of prepregnancy blood pressure, lipids, and glucose with length of pregnancy, and to assess whether the association between preterm delivery and later maternal cardiovascular disease may be due to common risk factors.

Study Design: Prospective study linking information of 3506 women in the HUNT Study with 4990 singleton births recorded in the Medical Birth Registry of Norway.

Results: Unfavorable prepregnancy levels of triglycerides, cholesterol, high-density lipoprotein-cholesterol, and glucose were associated with increased risk of preterm birth and shorter gestational length.

Hypertension in pregnancy and later cardiovascular risk: common antecedents?

Background: Preeclampsia and gestational hypertension are associated with increased risk for cardiovascular disease later in life. We have assessed whether the effect can be attributed to factors that operate in pregnancy or to prepregnancy risk factors that are shared by both disorders.

Methods And Results: Longitudinal data from 2 consecutive waves of a Norwegian population-based study (the Nord-Trøndelag Health Study [HUNT]) were combined with data from the Medical Birth Registry of Norway.

Hypertensive disorders in pregnancy and subsequently measured cardiovascular risk factors.

Objective: To study the association of hypertensive pregnancy disorders with modifiable risk factors for cardiovascular and metabolic diseases and to estimate the feasibility for early detection and prevention.

Methods: This was a prospective study of 15,065 women with a first singleton birth between 1967 and 1995, who later participated in a population study that included standardized measurements of blood pressure, serum lipids, and body mass index (BMI).

Results: Women with a history of hypertensive disorders in pregnancy (preeclampsia or gestational hypertension) had higher BMI, higher blood pressure, and unfavorable levels of total cholesterol, low-density lipoprotein cholesterol, and triglycerides.

Obstetric brachial plexus palsy: a birth injury not explained by the known risk factors.

Objective: To determine the incidence and prognosis of obstetric brachial plexus injuries and analyze associated risk factors.

Design: Analysis of prospectively collected information comprising all births from 1991 to 2000, with complete follow-up of affected children. Setting.

Prepregnancy cardiovascular risk factors as predictors of pre-eclampsia: population based cohort study.

Objective: To examine the effect of cardiovascular risk factors before pregnancy on risk of pre-eclampsia.

Design: Population based prospective study.

Setting: Linkage between a Norwegian population based study (Nord-Trøndelag health study, HUNT-2) and Norway's medical birth registry.
