Physical activities during pregnancy and type of delivery in nulliparae

Quality of life in women with normal pregnancy

Pregnancy affects a woman's physiological and psychological state. One of the most important aspects that requires attention is the quality of life of pregnant women. The quality of life of women during this period is influenced by a number of factors, such as back and pelvic pain, physiotherapy and physical activity, and also sexual satisfaction. Eighty-five women aged 21-40 years (30.80 ± 5.05) in pregnancy trimesters participated in the study: 17 women were in the first trimester, 32 women were in the second, and 36 women in the third trimester. The World Health Organisation Quality of Life (WHOQOL-BREF), Oswestry Disability Index (ODI) and the Sexual Satisfaction Scale for Women SSS-W-R15 were used to answer the research hypotheses. Respondents also provided information on questions regarding physiotherapy treatments and physical activity. Quality of life (WHOQOL-BREF) and disability due to back pain (ODI) showed a statistical association and relationship (p-value = 0.045, rho = - 0.22). Quality of life (WHOQOL-BREF) has an association with sexual satisfaction in pregnant women (SSS-W-R15) (p-value = 0.003, rho = 0.32). The trimester of pregnancy has an effect on ODI (p-value = 0.027). A significant effect occurred in a detailed comparison between the first and third trimesters of pregnancy (p-value = 0.026). The trimester also has an impact on quality of life (WHOQOL-BREF) (p-value = 0.002). In a detailed analysis, a significant effect occurred between the first and third trimesters of pregnancy (p-value = 0.001). Moreover, the trimester of pregnancy has an impact on sexual satisfaction (SSS-W-R15) (p-value = 0.027). After detailed statistical analysis, a significant effect occurred between trimesters one and three of pregnancy (p-value = 0.046). On the other hand, the number of days of physical activity performed by pregnant women per month and the type of physical activity had no effect on the ODI (p-value = 0.071). The type of physical activity performed by pregnant women also has no effect on ODI (p-value = 0.023). The number of physiotherapy treatments used has no effect on the ODI (p-value = 0.156). Type of physiotherapy treatment has no effect on ODI (p-value = 0.620). Normal pregnancy quality of life (WHOQOL) is related to ODI and sexual satisfaction (SSS-W-R15), while the trimester of pregnancy also has an impact on quality of life, disability due to back pain and sexual satisfaction.

Predictors of physical inactivity among pregnant women

It is recommended that pregnant women be physically active to promote maternal and child health. This study aimed to explore the prevalence of physical inactivity and its modifiable predictors in the three trimesters in Chinese pregnant women. Four hundred forty-four pregnant women completed the Pregnant Physical Activity Questionnaire in the first, second, and third trimesters. The prevalence of physical inactivity reached its highest (66.2%) in the first trimester and lowest (19.4%) in the second trimester. Pregnant women with inadequate physical activity knowledge and low self-efficacy were at higher risk for physical inactivity. Monitoring physical inactivity could be incorporated into antenatal care and start from the first trimester. Prenatal care professionals should take action to increase pregnant women's physical activity self-efficacy and knowledge to enhance their physical activity.

The Influence of Pregestational Body Mass Index and Physical Activity Patterns on Maternal, Delivery, and Newborn Outcomes in a Sample of Portuguese Pregnant Women: A Retrospective Cohort Study

Introduction

There is a linear association between pregestational body mass index (BMI) and almost all adverse pregnancy outcomes. Pregnancy is "a window of opportunities" in terms of changing behavior and improving awareness of healthy living. The proper assessment of physical activity levels, during pregnancy, determines trends, health benefits, and their effects over time. This study aims to describe maternal physical activity levels, stratified by pregestational BMI, verify the accomplishment of physical activity recommendations in pregnant women, and correlate pregestational BMI and physical activity accomplishment with maternal, delivery, and neonatal parameters.

Methods

A retrospective cohort study was carried out with 103 pregnant women. Physical activity levels were evaluated using a questionnaire and accelerometry. Pregestational BMI was obtained through the Quetelet formula and used the American College of Sports Medicine's guidelines were used to determine physical activity accomplishment levels. Continuous data were presented as mean and standard deviation and categorical data as numbers and percentages. The F test was used to examine the differences between groups.

Results

Pregnant women in the sample spent 42.9% of their time on household activities, and for pregnant women with obesity, 91.5% of the time was spent on sedentary activities. Women with normative BMI had higher levels of moderate-intensity activities. Only 15.8% of participants with obesity reached the international recommendations for physical activity practice and women who accomplished physical activity recommendations gained less weight during pregnancy. A high percentage of pre-obesity and obese pregnant women exceeded the recommendations for gestational weight gain and the gestational diabetes prevalence was higher in the obesity group (p = 0.03 between groups). Regarding delivery and neonatal parameters (Apgar score 1st, Apgar score 5th, birth weight, length and head circumference), no statistical differences were found when adjusted to a gestational week at birth, between BMI (p = 0.58; p = 0.18; p = 0.60; p = 0.34; p = 0.34, respectively) or physical activity (p = 0.12; p = 0.15; p = 0.83; p = 0.70; p = 0.70, respectively) groups.

Conclusion

Pregnant women with obesity, exhibit high levels of sedentary behavior, a high prevalence of gestational diabetes, and exceed recommended gestational weight gain. Healthcare professionals have a crucial role in promoting regular physical activity and lifestyle changes before and during pregnancy.

Physical Activity and the Impact of Continued Exercise on Health-Related Quality of Life Prior to and during Pregnancy: A German Cohort Study

The goal of this study was to examine how regular physical activity before and during pregnancy affected life quality throughout pregnancy. Between July 2020 and May 2021, 218 pregnant women were recruited from 11 outpatient clinics for this survey. Data were collected prospectively in a panel format beginning with the 10th gestational week over a 20-week period. Prior to pregnancy, a previous time point was also defined. The International Physical Activity Questionnaire, the EQ-5D-3L questionnaire, and the EQ-VAS questionnaire were used to collect data on the duration and intensity of daily physical exercises, as well as to assess health-related quality of life and self-estimated health status. The final survey included data from 113 women. During pregnancy, physical activity decreased dramatically. The duration of strenuous activities, but not moderate activities, was significantly reduced. Continuous physical activity independently predicted higher life quality scores at all points of assessment. Cases who participated in moderate and strenuous activities on a regular basis had higher self-estimated health status scores than cases who only participated in moderate activity. Instead of focusing solely on specific types of physical activity, we believe that strategies for motivating all pregnant women to be constantly active should be developed.

Evaluation of Physical Activity Level and Related Factors in Pregnancy During the COVID-19 Period

Objectives: It was aimed to determine the level of physical activity and related factors in pregnant women. Methods: The study is a mixed methods study. The participants are women applied to the pregnancy outpatient clinic of a hospital. The level of physical activity was assessed with the Pregnancy Physical Activity Questionnaire. Sociodemographic questions and seven questions of the International Physical Activity Environment Module were asked. Besides, in-depth interviews were conducted with 14 women. Results: The study was conducted with 304 women. The median age was 29.0 (18.0-40.0) years. The mean total activity and sedentary activity scores were 195.8 ± 107.9 and 37.22 ± 31.08 MET-hours/week, respectively. Pregnant women were mostly involved in light-intensity and housework/caregiving activities. Most of the participants mentioned that they were less active than pre-pregnancy period. The most common reasons for being less active were weakness, fatigue, lack of time and complaints such as low back pain and nausea. Conclusion: More than half of the pregnant women mentioned that they were less active during pregnancy. Thus, interventions should be planned to increase physical activity level of pregnant women.

The Effect of Online Supervised Exercise throughout Pregnancy on the Prevention of Gestational Diabetes in Healthy Pregnant Women during COVID-19 Pandemic: A Randomized Clinical Trial

(1) Background: to examine the effect of an online supervised exercise program during pregnancy on the prevention of GDM, and on maternal and childbirth outcomes. (2) Methods: we conducted a randomized clinical trial (NCT04563065) in 260 pregnant women without obstetric contraindications who were randomized into two study groups: intervention group (IG, N = 130) or control group (CG, N = 130). An online supervised exercise program was conducted from 8-10 to 38-39 weeks of pregnancy. (3) Results: no significant differences were found at baseline in maternal characteristics; nevertheless, certain outcomes showed a favorable trend towards the IG. A lower number and percentage of GDM cases were found in the IG compared to the CG (N = 5/4.9% vs. N = 17/16.8%, p = 0.006). Similarly, fewer cases of excessive maternal weight gain (N = 12/11.8% vs. N = 31/30.7%, p = 0.001) were found in the IG, and a lower percentage of instrumental deliveries (N = 8/11.3% vs. N = 13/15.1%) and c-sections (N = 7/9.9% vs. N = 20/23.3%, p = 0.046). (4) Conclusions: an online supervised exercise program can be a preventative tool for GDM in healthy pregnant women.

Level of Physical Activity in Pregnant Populations from Different Geographic Regions: A Systematic Review

The aim of this study was to examine the level of physical activity during pregnancy in different populations worldwide. An intensive search was carried out from February until May 2021. The inclusion criteria were original studies of healthy pregnant women, and the main study variable was the assessment of physical activity. A total of 110 out of 1451 studies were assessed for inclusion, using the Newcastle–Ottawa Scale for quality, and for the risk of bias. The 44 analyzed articles were divided into 5 tables according to the characteristics of the intervention and the validated instrument used to measure physical activity (PA). A total of 59.09% of the studies indicated that participants had a low level of physical activity during pregnancy. In addition, the median quality score of the studies was 7.12, and 77.27% of the studies were cataloged as having a high-quality score. Although international guidelines recommend that women without a contraindication engage in prenatal physical activity, the results of the present study show that the level of PA is too low for women to achieve scientifically proven maternal-fetal benefits. Failure to achieve the recommended levels of weekly physical activity could pose significant risks to maternal well-being.

Physical activity in gestational trimesters and perinatal outcomes in SUS puerperal women

OBJECTIVE

Test the association between the practice of physical activity (PA) according to the gestational trimesters and the occurrence of cesarean delivery, prematurity, and low birth weight in puerperal women assisted in the Unified Health System of Santa Catarina, Brazil.

METHODS

A cross-sectional study was conducted with a probabilistic sample of puerperal women who gave birth in public maternity hospitals in Santa Catarina from January to August 2019. The cesarean delivery outcome was self-reported, and information on premature birth (< 37 gestational weeks) and low birth weight (< 2,500 grams) were obtained from medical records. The practice of PA during pregnancy and according to each trimester was self-reported. Multivariate Logistic Regression analyses and interviews with 3,580 puerperal women were carried out.

RESULTS

PA practice during any period of pregnancy was reported by 20.6% of the sample, with a gradual reduction in prevalence according to the gestational trimester (16.2%, 15.4%, and 12.8%). The highest prevalences of outcomes concerning the total sample were observed in puerperal women who did not practice PA in the third trimester, with 43.9% for cesarean delivery, 7.7% for low birth weight, and 5.5% for premature birth. The odds of cesarean delivery (OR = 1.40; 95%CI 1.10–1.76) and low birth weight (OR = 1.99; 95%CI 1.04–3.79) were, respectively, 40% and 99% higher among puerperal women who did not practice PA in the third trimester of pregnancy when compared to those who practiced PA. There was no association between PA practice and prematurity.

CONCLUSION

Puerperal women who did not practice PA in the third trimester of pregnancy were more likely to have cesarean delivery and low birth weight newborns.

Changes in physical activity across pregnancy among Chinese women: a longitudinal cohort study

Background

Sufficient physical activity (PA) during pregnancy is beneficial for a woman’s health; however, the PA levels of Chinese women at different pregnancy stages are not clear. The aim of our study was to investigate PA changes during pregnancy and the association of population characteristics with PA change among Chinese women.

Methods

Data were obtained from 2485 participants who were enrolled in the multicentre prospective Chinese Pregnant Women Cohort Study. PA level was assessed in early pregnancy (mean = 10, 5–13 weeks of gestation) and again in mid-to-late pregnancy (mean = 32, 24–30 weeks of gestation) using the International Physical Activity Questionnaire short form (IPAQ-SF). Sufficient PA (≥ 600 MET min/week) in early pregnancy and insufficient PA in mid-to-late pregnancy indicated decreasing PA. Insufficient PA in early pregnancy and sufficient PA in mid-to-late pregnancy indicated increasing PA. The associations between demographic, pregnancy and health characteristics and PA changes were examined by multivariable logistic regression.

Results

Total energy expenditure for PA increased significantly from early (median = 396 MET min/week) to mid-to-late pregnancy (median = 813 MET min/week) (P < 0.001), and 55.25% of the participants eventually had sufficient PA. Walking was the dominant form of PA. Women with sufficient PA levels in early pregnancy were more likely to have sufficient PA in mid-to-late pregnancy (OR 1.897, 95% CI 1.583–2.274). Women in West China and those in Central China were most and least likely, respectively, to have increasing PA (OR 1.387, 95% CI 1.078–1.783 vs. OR 0.721, 95% CI 0.562–0.925). Smoking was inversely associated with increasing PA (OR 0.480, 95% CI 0.242–0.955). Women with higher educational levels were less likely to have decreasing PA (OR 0.662, 95% CI 0.442–0.991).

Conclusions

PA increased as pregnancy progressed, and walking was the dominant form of PA among Chinese women. Further research is needed to better understand correlates of PA change.

Developing a Physical Activity Intervention Strategy for Pregnant Women in Buffalo City Municipality, South Africa: A Study Protocol

Despite global awareness about the importance and health benefits of physical activity (PA) during pregnancy, several studies have reported a low prevalence of PA participation among pregnant women in both developed and developing countries. This means that most pregnant women do not meet the current PA recommended guideline of 150 min of moderate intensity PA per week. The global call to prioritise PA participation levels in the general population necessitates evaluating the factors affecting PA practice. Seemingly, pregnant women mostly from low-to-middle income countries like South Africa are often predisposed to adverse pregnancy outcomes, possibly because of limited access to, and knowledge of, improved pregnancy and health outcomes as a result of PA participation. Physical activity has been sparsely studied among pregnant South African women, and specifically, there is no known study that assesses the PA levels, patterns, beliefs, sources of information, perceived benefits, barriers, attitudes of pregnant women concerning PA and exercise participation; nor one that explores the perspectives of healthcare providers regarding prenatal PA in the Eastern Cape Province. In addition, no PA intervention strategy exists to promote PA participation in the region. This study, in attempting to fill these gaps in knowledge, adopts two phases. In Phase I, a concurrent mixed-method (quantitative and qualitative) approach assesses the following factors related to PA participation in pregnant women: participation levels, beliefs, attitudes, perceived benefits, barriers to uptake and sources of information. It further ascertains if healthcare professionals are sufficiently informed about PA and if they are advising pregnant women about the need for PA participation during pregnancy. Data will be collected through a structured questionnaire, interviews and focus group discussions. Information on socio-demographic and maternal characteristics will be obtained, and the Pregnancy Physical Activity Questionnaire (PPAQ) will assess PA during pregnancy. A sample size of 384 pregnant women is the required minimum sample for an infinite population at a confidence level of 95%, a precision level of ± 5% and at a prevalence of PA or exercise during pregnancy of 50% (p < 0.05); however, a sample size larger than the minimum number necessary will be recruited to account for possible attrition and to protect against possible data loss. Data will be analysed using a multiple logistic regression to determine the factors that predict sedentary or moderate PA levels and chi-squared analysis to determine the associations between the PA levels of the participants and socio-demographic and clinical variables. The study will assess the data collected on the above-mentioned variables and draw conclusions based on patterns and themes that emerge during analysis. Phase II of the study focuses on strategy development and validation to facilitate the promotion of PA during pregnancy. The developed strategy will be validated through the application of the Delphi technique and the administration of a checklist to selected key stakeholders through organised workshops. Understanding the level and correlates of PA participation among this special population is fundamental to designing intervention strategies to enhance their understanding of, and participation in, PA and exercise. Furthermore, this study's findings will inform facility-based healthcare providers about the need to integrate health education on PA and pregnancy into antenatal and postnatal care visits in the setting.

Pregnancy physical activity questionnaire (PPAQ): Translation and cross cultural adaption of an Arabic version

Introduction

Physical activity level during pregnancy is unknown in Middle Eastern and North African countries, since no valid tools assessing it exist in Arabic. The aim of this study is to culturally adapt and translate to Arabic an internationally validated instrument, the Pregnancy Physical Activity Questionnaire (PPAQ), and to measure the physical activity of pregnant women using the adapted PPAQ, Arabic version. This tool is time-sparing, self-administered and is the only one taking into account childcare and household chores.

Methods

After following the guidelines for translation and back-translation by certified translators, a committee composed of professionals in the field reviewed each item of the PPAQ, for its comprehensibility. This Arabic version of the PPAQ was tested on a sample of 179 pregnant Lebanese women, from different educational backgrounds, socioeconomic status and gestational ages.

Results

Cross-cultural adaptations were applied on the newly translated PPAQ in Arabic version, thus questions referring to some types of outdoor activities were excluded from the final format. Our results reported that 51% and 1.7% of women engage respectively in light and high intensity physical activity, while 18% had a sedentary lifestyle. Occupational type of activities were significantly more performed by women having a higher education (p value 0.001), as opposed to those who attended only high school, who were physically more active in household activities (p value 0.038). Second trimester was a period where pregnant women were active for household, caregiving (p value 0.031), whereas women in their third trimester were physically more active in occupational activities (p value 0.001). Sport-oriented activities were performed by women reporting a good physical status (p value 0.03). Age and crowding index were significantly correlated with occupational, household and caregiving activities (p values 0.004, 0.008 respectively). No significant correlations were observed with pre-gestational body mass index and the physical activity levels.

Conclusion

A valid tool will help researchers in Arab countries identify physical activity levels of pregnant women and consequently emit specific guidelines relative to the importance and the benefits of a daily active lifestyle throughout gestation.

Factors Associated with the Leisure-Time Physical Activity (LTPA) during the First Trimester of the Pregnancy: The Cross-Sectional Study among Pregnant Women in Serbia

Background: The benefits of physical activity during pregnancy include lower maternal weight gain, a lower likelihood of gestational diabetes, low back pain, preeclampsia, preterm delivery, caesarian delivery, and macrosomia. This study aimed to examine the factors associated with insufficient leisure-time physical activity (LTPA) during the first trimester. Methods: A cross-sectional study was conducted at the Clinic for Obstetrics and Gynecology of Clinical Center of Serbia, Belgrade, between January and June of 2018. The final analyses included 162/175 pregnant women. The questionnaire was used to obtain social characteristics, pregnancy, and lifestyle characteristics (Pregnancy Risk Assessment Monitoring System-PRAMS), pre-pregnancy LTPA (International Physical Activity Questionnaire-IPAQ), and LTPA during the first trimester (Pregnancy Physical Activity Questionnaire-PPAQ). Women were classified into two groups of sufficient and insufficient LTPA during the first trimester based on the recommendations of the World Health Organization. Multivariate logistic regression analysis was applied. Results: A total of 27.2% of the women had insufficient LTPA during pregnancy. Insufficient LTPA during pregnancy was associated with <12 years of education (OR: 2.3, 95% CI: 1.05-5.04), self-rated financial status as poor (OR: 0.34, 95% CI: 0.14-0.79), and hours spent walking before pregnancy (OR: 0.87, 95% CI: 0.77-0.99). Conclusions: Our results can help direct health care professionals advice for women who are planning pregnancy towards walking as it seems to be sustained during pregnancy.

Physical Activity Questionnaires for Pregnancy: A Systematic Review of Measurement Properties

Background

In order to assess physical activity (PA) during pregnancy, it is important to choose the instrument with the best measurement properties.

Objectives

To systematically summarize, appraise, and compare the measurement properties of all self-administered questionnaires assessing PA in pregnancy.

Methods

We searched PubMed, Embase, and SPORTDiscus with the following inclusion criteria: (i) the study reported at least one measurement property (reliability, criterion validity, construct validity, responsiveness) of a self-administered questionnaire; (ii) the questionnaire intended to measure PA; (iii) the questionnaire was evaluated in healthy pregnant women; and (iv) the study was published in English. We evaluated results, quality of individual studies, and quality of evidence using a standardized checklist (Quality Assessment of Physical Activity Questionnaires [QAPAQ]) and the GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) approach.

Results

Seventeen articles, reporting 18 studies of 11 different PA questionnaires (17 versions), were included. Most questionnaire versions showed insufficient measurement properties. Only the French and Turkish versions of the Pregnancy Physical Activity Questionnaire (PPAQ) showed both sufficient reliability and construct validity. However, all versions of the PPAQ pooled together showed insufficient construct validity. The quality of individual studies was usually high for reliability but varied considerably for construct validity. Overall, the quality of evidence was very low to moderate.

Conclusions

We recommend the PPAQ to assess PA in pregnancy, although the pooled results revealed insufficient construct validity. The lack of appropriate standards in data collection and processing criteria for objective devices in measuring PA during pregnancy attenuates the quality of evidence. Therefore, research on the validity of comparison instruments in pregnancy followed by consensus on validation reference criteria and standards of PA measurement is needed.

Physical Activity and Risk of Cesarean Delivery in Hispanic Women

BACKGROUND

Rates of cesarean delivery continue to increase among Hispanics, the largest minority group in the United States. Prior studies of the relationship between physical activity and cesarean delivery have been conflicting, limited by questionnaires not validated for pregnancy, and conducted primarily among non-Hispanic whites.

METHODS

We evaluated this association among participants (n = 1313) in Proyecto Buena Salud, a prospective cohort of Hispanic women conducted from 2006 to 2011. Physical activity was measured via the Pregnancy Physical Activity Questionnaire.

RESULTS

In total, 320 (24.4%) participants delivered via cesarean. In multivariable analyses, increasing levels of sedentary activity in mid/late pregnancy were associated with higher odds of cesarean delivery (odds ratio = 1.54; 95% confidence interval, 1.02-3.33; P_trend = .05); however, there were no clear patterns between physical activity and cesarean delivery. When we repeated the analysis excluding planned cesarean deliveries (n = 126), high levels of prepregnancy moderate-intensity physical activity (odds ratio = 0.61; 95% confidence interval, 0.38-0.99) and increasing moderate-intensity physical activity in mid/late pregnancy (P_trend = .03) were associated with reduction in odds. Increasing levels of household/caregiving physical activity in pre and mid/late pregnancy were associated with a 50% reduction in odds (P_trend < .05).

CONCLUSIONS

In this prospective cohort of Hispanics, sedentary activity increased odds of cesarean delivery, and moderate-intensity and household/caregiving physical activity reduced odds of unplanned cesarean deliveries.

Relationships between Physical Activity and Quality of Life in Pregnant Women in the Second and Third Trimester

BACKGROUND

The problem of an inadequate level of physical activity (PA) is important in the context of its relationship with the quality of life (QoL) of pregnant women. The aim of this study was to analyze the relationships between PA and QoL among pregnant women.

METHODS

The study analyzed 346 questionnaires filled in by pregnant women (157 in the second trimester and 189 in the third). The tool used for assessment of PA was the Pregnancy Physical Activity Questionnaire-Polish version (PPAQ-PL). The quality of life (QoL) was assessed by the World Health Organization Quality of Life Questionnaire-short form (WHOQoL-Bref). The results obtained from the PPAQ-PL and WHOQoL-Bref questionnaires for women in the second and third trimesters of pregnancy and intergroup differences were analyzed.

RESULTS

There was a significant correlation in the group of women in the second trimester of pregnancy between quality of life in the physical health domain and the intensity and type of physical activity. The women who rated their quality of life higher in this domain declared higher energy expenditures (EE) associated with vigorous activity (R = 0.159, p ≤ 0.05), as well as with occupational activity (R = 0.166; p ≤ 0.05) and sport/exercise activity (R = 0.187; p ≤ 0.05). In women in the third trimester, higher EE related to sport/exercise activity coincided with higher assessments of the overall quality of life (R = 0.149, p ≤ 0.05) and general health (R = 0.170, p ≤ 0.05). In the case of the psychological domain (R = 0.161, p ≤ 0.05) and social relationship domain (R = 0.188; p ≤ 0.05) of QoL, positive correlations occurred with EE related to vigorous activity. In contrast, high assessment of physical health domain coincided with higher EE related to occupational activity (R = 0.174; p ≤ 0.05).

CONCLUSIONS

Our study makes an important contribution to knowledge concerning the correlations between PA and QoL in pregnancy. The results suggest the need for improvement in prenatal care and promotion of PA programs for pregnant women.

Physical activities (exercises or choreses) during pregnancy and mode of delivery in nulliparous women: A prospective cohort study

OBJECTIVE

The aim of this study was to investigate changes in physical activities during pregnancy and the relationship between physical activity and unplanned caesarean sections (CSs).

MATERIALS AND METHODS

A cohort study design was carried out. A cohort of 2029 pregnant women was established when they received prenatal care at 18-22 weeks of gestation in a medical center in southwest Iran. Participants were asked to recall their levels of physical activity during pre-pregnancy. The data were processed using Statistics/Data Analysis. To compare activities the chi-square was used to identify significant differences between the groups. A multiple logistic regressian was used to identify the association between activities and delivery mode as well as controlling potential confounding variables. In the analyses, the level of significance was set at P < 0.05.

RESULTS

In total, 2029 pregnant women participated in the study, among which 1334 (65.84%) underwent CSs and 692 (34.16%) underwent NVDs. The study indicated the odds ratio of CS was 0.68 (95% CI: 0.47-0.97) for a pregnant woman who increased her level of activity during pregnancy compared to pre-pregnancy.

CONCLUSION

The results of this study showed that regular and standard physical activities during pregnancy can reduce the risk of caesarean section in pregnant women. These findings can be important in convincing health care providers to prescribe regular and standard physical activities for pregnant women during pregnancy.

Comparing the Effects of Progressive Muscle Relaxation and Physical Activity on Pregnant Women's General Health

Background:

Pregnancy is important because maternal health and well-being directly affects another person's life. This study aimed to compare the effects of progressive muscle relaxation (PMR) and physical activity (PA) on the general health of pregnant women.

Materials and Methods:

This randomized clinical trial was conducted among 96 primiparous women enrolled in a prenatal clinic in Tehran (Iran) between May 3, 2013 and August 7, 2013. The participants were selected through convenience sampling over 3 weeks and randomly assigned to the PMR, PA, and control groups, comprising 32 participants each. Six participants did not complete the follow-up measurement (N = 90). The PMR group underwent three sessions of 1.5–2 h in theoretical and practical training, and in the PMR group, training was given in groups of three to four persons. Both groups performed exercises at home for 8 weeks and recorded them in daily report sheets. The general health of all three groups was assessed before and after intervention by using the General Health Questionnaire-28.

Results:

Differences in the mean (SD) general health scores obtained before and after intervention in the PMR, PA, and control groups were 15.63 (5.73), 19.11 (7.79), and 8.27 (2.14), respectively. One-way analysis of variance test showed a significant difference between the three groups (F = 28.10; p < 0.001).

Conclusions:

As the study results confirm the positive effects of PMR and PA on the subscales of the general health of pregnant women, the two techniques are recommended to promote the general health of pregnant women.

Associations between quality of life, physical activity, worry, depression and insomnia: A cross-sectional designed study in healthy pregnant women

Health-related quality of life (QOL) is reported to be reduced during pregnancy. Associations between QOL, physical activity (PA), insomnia, depression and worry are insufficiently investigated among pregnant women. The aim of this study was to evaluate QOL and PA patterns among healthy pregnant women, and to examine how QOL might correlate to PA, sleep, worry and depression. This is an observational cross-sectional study, conducted among a convenient sample of 141 healthy pregnant women using five questionnaires: WHOQOL-brief (WHO quality of life questionnaire, brief version, ISI (Insomnia Severity Index), PSWQ (Penn State Worry Questionnaire), ZSRDS (Zung Self-Rating Depression Scale), and Pregnancy Physical Activity Questionnaire (PPAQ). Pre-gestational BMI was inversely correlated to overall health while education was positively correlated to psychological health, social relationships and environment domains. Smoking before and during pregnancy significantly impacted the general health and psychological health. Total and light PA were positively correlated to psychological health and social relationships. Sports/exercise showed positive correlations with several QOL domains. Insomnia and depression were significantly associated with a decrease in all domains of QOL, while worries were associated with a decrease in physical, psychological and environmental domains. There were significant negative correlations between ZSRDS scores and total activity. PA, worries, depression and insomnia affected QOL during pregnancy. Furthermore, pregnant women presenting depression had a reduced total PA. Sleep and mental health as well as encouraging PA during pregnancy are necessary to improve the quality of life of pregnant women.
