Physical activity, sitting time and sleep duration before and during pregnancy and pregnancy outcomes: A prospective panel study

The role and outcomes of music therapy during pregnancy: a systematic review of randomized controlled trials

INTRODUCTION

The abundant functions of music and its effects on human's mental and physical health have been verified since ancient times, but rarely received attention as an alternative obstetric intervention.

OBJECTIVE

This study aims to investigate the benefits of music therapy on prenatal and delivery experiences of pregnant women.

METHOD

A systematic search for articles was conducted in electronic databases including CINAHL, Web of Science, PubMed/Medline, and CNKI. A total of 240 articles were identified, and 17 studies were selected for this review. The extracted data included author, year, location, sample size, intervention phase, type of music, music therapy strategy, measuring instruments, and results. The data were organized chronologically based on the publication year of each study.

RESULT

The articles indicated that music therapy has advantages in reducing pain during childbirth, lowering anxiety and stress levels in mothers, improving sleep quality, and increasing fetal movements, basal fetal heart rate, and accelerations.

CONCLUSION

Based on the findings, it can be concluded that music therapy is an effective approach to enhance the experience of pregnant women during pregnancy and delivery. Therefore, its implementation in obstetrical clinical practice is highly recommended.

Impact of maternal posture on fetal physiology in human pregnancy: a narrative review

In numerous medical conditions, including pregnancy, gravity and posture interact to impact physiology and pathophysiology. Recent investigations, for example, pertaining to maternal sleeping posture during the third trimester and possible impact on fetal growth and stillbirth risk highlight the importance and potential clinical implications of the subject. In this review, we provide an extensive discussion of the impact of maternal posture on fetal physiology from conception to the postpartum period in human pregnancy. We conducted a systematic literature search of the MEDLINE database and identified 242 studies from 1991 through 2021, inclusive, that met our inclusion criteria. Herein, we provide a synthesis of the resulting literature. In the first section of the review, we group the results by the impact of maternal posture at rest on the cervix, uterus, placenta, umbilical cord, amniotic fluid, and fetus. In the second section of the review, we address the impact on fetal-related outcomes of maternal posture during various maternal activities (e.g., sleep, work, exercise), medical procedures (e.g., fertility, imaging, surgery), and labor and birth. We present the published literature, highlight gaps and discrepancies, and suggest future research opportunities and clinical practice changes. In sum, we anticipate that this review will shed light on the impact of maternal posture on fetal physiology in a manner that lends utility to researchers and clinicians who are working to improve maternal, fetal, and child health.

Physical Activity, Sedentary and Sleep Phenotypes in Women During the First Trimester of Pregnancy

OBJECTIVES

Patterns of physical behaviors including physical activity, sedentary time, and sleep are unknown during pregnancy, but are likely to influence health outcomes. The purpose was to first identify "physical behavior phenotypes" from accelerometer-measured physical behaviors in pregnant women during the first trimester and secondly, to explore the associations between the identified phenotypes with demographic variables and body-mass-index (BMI).

METHODS

Data were from the Glowing Study (gov ID: NCT01131117), collected between 2011 and 2017 with accelerometer-measured physical behaviors of women in their 12th week of pregnancy. Latent class analysis was used to identify patterns of total physical activity, sleep time, sedentary time, and variation in physical activity. Maternal Body-Mass-Index (BMI). BMI and sociodemographic characteristics were compared between physical behavior phenotypes.

RESULTS

A total of 212 pregnant women were included in the study (mean age 30.2 years (range 22.1 to 42.4), mean days wear 4.3 (SD 0.7)). Three physical behavior phenotypes were identified from the four physical behavior constructs: low sedentary and stable activity (n = 136, 64%), variable activity (n = 39, 18%), high sedentary and low sleep (n = 37, 17%). BMI, race, and education were significantly different between the three phenotypes, with the low sedentary and stable activity phenotype having the lowest BMI and a higher percentage of white and college educated women.

CONCLUSIONS FOR PRACTICE

Total physical activity and physical behavior phenotypes during the first trimester were associated with early-pregnancy BMI, race, and education. Future research should examine whether these physical behavior phenotypes are associated with maternal and child health outcomes.

Maternal sleep during pregnancy and adverse pregnancy outcomes: a systematic review and meta-analysis

AIM/INTRODUCTION

Sleep problem is an important public health concern worldwide. We conducted a meta-analysis to quantitatively evaluate whether sleep duration associated with pregnancy outcomes, and the associations were modified by important characteristics of studies.

MATERIALS AND METHODS

Basing on PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL) databases, we searched for the published literature related to maternal sleep duration and adverse pregnancy outcomes before 30 June, 2021. We conducted risk of bias assessment, subgroup analyses and sensitivity analysis. The relative risks (RR) or odds ratios (OR) with 95% confidence intervals (CI) were used to estimate the pooled effects.

RESULTS

5246 references were identified through databases searching, 41 studies were included in the study. Pregnant with short sleep duration had 1.81 times (95% CI 1.35-2.44, P < 0.001) risk of gestational diabetes mellitus (GDM). The association between short sleep duration and the risk of gestational hypertension (GH), cesarean section (CS), low birthweight (LBW), preterm birth (PTB) and small for gestational age (SGA) were not significant (P > 0.05). Furthermore, long sleep duration was significantly correlated with GDM (OR 1.24. 95% CI 1.12-1.36, P < 0.001) and CS (OR 1.13. 95% CI 1.04-1.22, P = 0.004), while long sleep duration was not linked with GH, LBW, PTB and SGA (P > 0.05).

CONCLUSIONS

Short / long sleep duration appeared to be associated with adverse pregnancy outcome, specifically with an increased risk of GDM. Sleep should be systematically screened in the obstetric population.

Decreased Physical Activity during Pregnancy Is Associated with Excessive Gestational Weight Gain

The majority of pregnant women in Taiwan are not considered physically active. During pregnancy, many women decrease their physical activity levels when compared to pre-pregnancy. The purpose of this study was to examine the association between decreased physical activity from pre-pregnancy to pregnancy and excessive gestational weight gain (GWG). This study applied a prospective panel design. Recruitment was conducted at six medical facilities in Taiwan and lasted from August 2016 to April 2017. Physical activity levels were determined both before and during pregnancy using the International Physical Activity Questionnaire—Short Form, with data subsequently being transformed into METs-min/week. Excessive GWG was determined based on the body mass index (BMI) specific GWG range. We recruited 747 pregnant women in their second trimester and followed them through to one-month postpartum. About 40% of participants (41.2%) exhibited excessive GWG. Physical activity decreased from an average of 2261 (SD = 3999) to 1252 (SD = 2258) METs-min/week from pre-pregnancy to pregnancy (p < 0.0001). Controlling for age and pre-pregnancy BMI, a logistic regression model revealed that a decline in physical activity of > 4000 METs-min/week from pre-pregnancy to pregnancy was associated with an increased risk for excessive GWG (OR = 2.83, 95% CI: 1.27–4.43). A substantial decrease in physical activity from pre-pregnancy to pregnancy was a risk factor for excessive GWG. Although most women decreased their physical activity during pregnancy, only those pregnant women who were physically active pre-pregnancy could show the kind of large decrease that resulted in excessive GWG. Health professionals should continue to develop strategies for counteracting the problematic trend of decreasing PA during pregnancy among low-risk pregnant women.

Fatigue and sleep quality in different trimesters of pregnancy

OBJECTIVES

Fatigue is one of the most common and persistent complaints of pregnant women. Increased severity of fatigue during pregnancy can increase the risk of preterm labor, prolonged labor, cesarean section, and postpartum depression. Therefore, this study aimed to determine the fatigue status in different trimesters of pregnancy and its relationship with sleep quality in pregnant women.

MATERIAL AND METHODS

This cross-sectional study was performed by two-stage cluster sampling on pregnant women referred to Tabriz health centers. Data were collected using socio-demographic questionnaire, multidimensional assessment of fatigue and Pittsburgh sleep quality index.

RESULTS

Among the 605 pregnant women studied, 94.2% of women suffered from fatigue during pregnancy. The mean (standard deviation) of fatigue score in the first, second and third trimesters of pregnancy was 23.53 (8.05), 25.78 (6.56) and 26.46 (6.72), respectively. There was also significant reverse correlation between total fatigue score with total sleep quality score (p=0.031) and with an increase in fatigue, sleep quality was reduced.

DISCUSSION

The findings of this study may be used to design interventional measures for fatigue and medical care to improve quality of sleep in pregnancy.
