Caesarean sections among immigrant women with different levels of education.

Background: Studies have shown a high incidence of emergency caesarean sections among immigrant women, especially those born in Sub-Saharan Africa, but the risk of planned and emergency caesarean section varies with the mother's level of education. The proportion of women with little or no education is higher among those born in Sub-Saharan Africa and other low- and middle-income countries than those born in Norway. We therefore wanted to investigate the relationship between maternal birthplace, level of education and risk of caesarean section.

Preconception leisure-time physical activity and family history of stroke and myocardial infarction associate with preterm delivery: findings from a Norwegian cohort.

Background: Preterm birth poses short and long-term health consequences for mothers and offspring including cardiovascular disease sequelae. However, studies evaluating preexisting family history of cardiovascular disease and risk factors, such as physical activity, as they relate prospectively to risk of delivering preterm are lacking.

Objectives: To evaluate whether preconception past-year weekly leisure-time physical activity or a family history of stroke or of myocardical infarction prior to age 60 years in first degree relatives associated, prospectively, with preterm delivery.

Association between Maternal Origin, Pre-Pregnancy Body Mass Index and Caesarean Section: A Nation-Wide Registry Study.

Aims: To explore the association between maternal origin and birthplace, and caesarean section (CS) by pre-pregnancy body mass index (BMI) and length of residence.

Methods: We linked records from 118,459 primiparous women in the Medical Birth Registry of Norway between 2013 and 2017 with data from the National Population Register. We categorized pre-pregnancy BMI (kg/m) into underweight (<18.

Leisure-time physical activity before pregnancy and risk of hyperemesis gravidarum: a population-based cohort study.

Introduction: Women who experience severe nausea and vomiting in early pregnancy are less likely to participate in leisure-time physical activity (LTPA) during pregnancy. Whether LTPA before pregnancy is associated with hyperemesis gravidarum (HG) has not yet been studied. The aim of the study was to estimate associations between prepregnancy LTPA and HG in pregnancy.

Does progestin-only contraceptive use after pregnancy affect recovery from pelvic girdle pain? A prospective population study.

Objective: To estimate associations of progestin-only contraceptives with persistent pelvic girdle pain 18 months after delivery.

Methods: Prospective population based cohort study during the years 2003-2011. We included 20,493 women enrolled in the Norwegian Mother and Child Cohort Study who reported pelvic girdle pain in pregnancy week 30.

Exercise in pregnancy: an association with placental weight?

Background: Women with high levels of physical exercise have an increased demand for oxygen and nutrients. Thus, in pregnancies of women with high levels of exercise, it is conceivable that the supply of oxygen and nutrients to the placenta is suboptimal, and growth could be impaired.

Objective: The objective was to study the association of frequency of exercise during pregnancy with placental weight and placental to birthweight ratio.

Exercise during pregnancy and risk of cesarean delivery in nulliparous women: a large population-based cohort study.

Background: Vaginal delivery for the first birth is of great importance for further obstetric performance for the individual woman. Given the rising cesarean delivery rates worldwide over the past decades, a search for modifiable factors that are associated with cesarean delivery is needed. Exercise may be a modifiable factor that is associated with type of delivery, but the results of previous studies are not conclusive.

Pelvic pain after childbirth: a longitudinal population study.

In this longitudinal population study, the aims were to study associations of mode of delivery with new onset of pelvic pain and changes in pelvic pain scores up to 7 to 18 months after childbirth. We included 20,248 participants enrolled in the Norwegian Mother and Child Cohort Study (1999-2008) without preexisting pelvic pain in pregnancy. Data were obtained by 4 self-administered questionnaires and linked to the Medical Birth Registry of Norway.

Exercise level before pregnancy and engaging in high-impact sports reduce the risk of pelvic girdle pain: a population-based cohort study of 39 184 women.

Objective: To examine whether an association exists between exercise levels pre-pregnancy and pelvic girdle pain in pregnancy. Pelvic girdle pain in pregnancy has been associated with physical inactivity, a risk factor for adverse pregnancy outcomes.

Methods: We used data from a population-based cohort study including 39 184 nulliparous women with a singleton pregnancy enrolled in the Norwegian Mother and Child Cohort study.

Guidelines for Physical Activity during Pregnancy: Comparisons From Around the World.

Introduction: Women attain numerous benefits from physical activity during pregnancy. However, due to physical changes that occur during pregnancy, special precautions are also needed. This review summarizes current guidelines for physical activity among pregnant women worldwide.

Summary of international guidelines for physical activity after pregnancy.

Postpartum physical activity can improve mood, maintain cardiorespiratory fitness, improve weight control, promote weight loss, and reduce depression and anxiety. This review summarizes current guidelines for postpartum physical activity worldwide. PubMed (MEDLINE) was searched for country-specific government and clinical guidelines on physical activity after pregnancy through the year 2013.

Physical activity during pregnancy and language development in the offspring.

Background: In rodents, physical activity during pregnancy has been associated with improved learning and memory in the offspring. We used data from the Avon Longitudinal Study of Parents and Children (born in 1991-92) to investigate maternal physical activity during pregnancy and offspring language development.

Methods: At 18 weeks of gestation, women reported the hours per week they participated in 11 leisure-time physical activities and the hours per week spent in general physical activity (leisure, household and occupational).

Do pregnant women follow exercise guidelines? Prevalence data among 3482 women, and prediction of low-back pain, pelvic girdle pain and depression.

Purpose: We describe exercise level in mid-pregnancy, associated sociodemographic variables, and investigate the association between exercise in mid-pregnancy and subsequent low-back pain, pelvic girdle pain and depression at 32 weeks of pregnancy.

Material And Methods: The study included 3482 pregnant women participating in the Akershus Birth Cohort study (response rate 80.5%).

Health benefits of physical activity during pregnancy: an international perspective.

While early studies on the effects of leisure time physical activity (LTPA) during pregnancy were concerned about possible harm to the mother or fetus, these fears have not been substantiated. Instead, a growing body of literature has documented several health benefits related to pregnancy LTPA. The purpose of this article was to synthesize evidence from epidemiological studies conducted in the United States, Canada, and Scandinavia on the benefits of LTPA and exercise during pregnancy with regard to maternal health, pregnancy outcomes, and child health.
