Aerobic exercise during pregnancy improves health-related quality of life: a randomised trial

Significance of Physical Exercise in Pregnancy: Comparison of Short and Long Exercise Programs

BACKGROUND

Several musculoskeletal changes occur in pregnancy, particularly in the abdominal region. The aim of this study was to search and compare the effects of long (LEP) and short exercise programs (SEP) in terms of the satisfaction of the needs of pregnant women.

METHODS

This study consisted of 2 groups: LEP (n=16) and SEP (n=16). Muscle thickness measurements determined by ultrasound, the 6 minute walk test, Pregnancy Physical Activity Questionnaire, Visual Analogue Scale, Oswestry Disability Index, and Short Form-36 Quality of Life Questionnaire were the study variables. Evaluations were done at the 16th (baseline), 24th, and 32nd gestational weeks. The LEP consisted of 20 and the SEP consisted of 9 exercises, which were applied for 16 weeks until the 32nd gestational week.

RESULTS

Emotional role limitation and pain scores of quality of life, 6 minute walk test, and occupational physical activity were found to be better in the LEP group at the 24th gestational week (p=0.043, p=0.049, p=0.049, p=0.026). At the 32nd gestational week, the 6 minute walk test and occupational physical activity were found to be higher in the LEP group (p=0.006, p=0.017). Additionally, rectus abdominis and bilateral diaphragm muscle thicknesses, "moderate intensity and sports physical activity" and "vitality and emotional well-being" were increased over time with the LEP (p+<+0.05 for all). On the other hand, unilateral diaphragm muscle thickness, sports physical activity level, and vitality were improved with the SEP (p+<+0.05 for all).

CONCLUSIONS

The SEP and LEP both have beneficial effects in pregnant women. However, the LEP increases physical activity level, functional capacity, and quality of life more than the SEP during the later stages of pregnancy.

Influence of a Concurrent Exercise Training Program on Health-Related Quality of Life During Advanced Pregnancy: The GESTAFIT Project

BACKGROUND

Health-related quality of life (HRQoL) may be altered during pregnancy due to pregnancy-related changes in all domains of women's health.

HYPOTHESIS

A supervised concurrent exercise-training program from the 17th gestational week until birth positively influences HRQoL.

STUDY DESIGN

Randomized controlled trial.

LEVEL OF EVIDENCE

Level 1.

METHODS

Eighty-six pregnant women (age, 33.1 ± 4.6 years; prepregnancy body mass index, 23.5 kg/m2), divided into exercise (n = 41) and control (n = 45) groups, participated in this study (per-protocol basis). The exercise group followed a 60-min, 3 days/week, concurrent (aerobic + resistance) exercise training program. HRQoL was assessed with the 36-Item Short Form Health Survey (SF-36), where higher scores (0-100) indicate better HRQoL.

RESULTS

After adjusting for potential confounders, the exercise group decreased 16.1 points less than the control group in the SF-36 physical functioning domain [between-group differences (B): 95% confidence interval (CI), 9.02 to 23.22; P < 0.01], and 4.5 points less in the SF-36 physical component summary than the control group (between-group differences (B): 95% CI, 0.65 to 8.28; P = 0.02). Intention-to-treat basis analyses depicted similar results, where the exercise group decreased 10.03 points less than the control group the in the SF-36 social functioning domain (between-group differences (B): 95% CI, 0.39 to 19.68; P = 0.04).

CONCLUSION

A supervised concurrent exercise training program ameliorates HRQoL decreases along gestation. Although HRQoL decreased throughout pregnancy in both groups, this impact was less in the exercise group, especially in the SF-36 physical functioning, the SF-36 social functioning, and the SF-36 physical component summary.

CLINICAL RELEVANCE

Healthcare providers may encourage pregnant women to exercise in this physiological stage for a better HRQoL throughout pregnancy.

Effects of anxiety, depression, social support, and physical health status on the health-related quality of life of pregnant women in post-pandemic Korea: a cross-sectional study

PURPOSE

This study aimed to examine the effects of anxiety, depression, social support, and physical health status on the health-related quality of life of Korean pregnant women using Spilker's quality of life model.

METHODS

This was a cross-sectional study with a correlational design. The participants included 166 pregnant women who were recruited via convenience sampling at two healthcare centers in South Korea. Questionnaires were collected from April 22 to May 29, 2023, in two cities in South Korea. The EuroQol-5D-3L, General Anxiety Disorder-7, Patient Health Questionnaire-2, Perceived Social Support through Others Scale-8, and EuroQol visual analog scale were used to assess the study variables. The t-test, Pearson correlation coefficients, and multiple regression tests were conducted using IBM SPSS ver. 26.0.

RESULTS

Statistically significant correlations were identified between the health-related quality of life of pregnant women and anxiety (r=.29, p<.001), depression (r=.31, p<.001), social support (r=-.34, p<.001), and physical health status (r=-.44, p<. 001). Physical health status (β=-.31, p<.001) and social support (β=-.21, p=.003) had the greatest effect on health-related quality of life (F=15.50, p<.001), with an explanatory power of 26.0%.

CONCLUSION

The health-related quality of life of pregnant women was affected by social support and physical health status. This study demonstrated that physical health and social support promotion can improve the health-related quality of life of pregnant women. Healthcare providers should consider integrating physical health into social support interventions for pregnant women in the post-pandemic era.

Physical Activity and Self-Perception of Mental and Physical Quality of Life during Pregnancy: A Systematic Review and Meta-Analysis

Self-perception of health status (quality of life) is considered one of the best indicators of health and well-being. However, during pregnancy, it could be impacted not only by physiological and anatomical changes, but by poor lifestyle habits like high sedentary behaviour or bad nutrition. This study assesses the effects of physical activity RCT interventions during pregnancy on both mental and physical components of quality of life. A systematic review and two meta-analyses were performed (PROSPERO registration number: CRD42022370467). Of the 207 articles captured both in English and Spanish, seven articles were deemed eligible for inclusion. The two analyses performed found that physically active pregnant women had better scores of mental self-perception of quality of life (z = 2.08, p = 0.04; SMD = 0.34, 95% CI = 0.02, 0.67, I2 = 76%, Pheterogeneity = 0.0004) and in physical self-perceived health status (z = 2.19, p = 0.03; SMD = 0.33, 95% CI = 0.03, 0.63, I2 = 71%, Pheterogeneity = 0.002) compared to control group pregnant women. Physical activity interventions could potentially increase mental and physical self-perception of quality of life during pregnancy.

Self-Care Mobile Application for South Korean Pregnant Women at Work: Development and Usability Study

Background

Pregnant women at work often encounter barriers to participating in prenatal education or conducting appropriate self-care practices due to their working conditions.

Purpose

We aimed at developing a mobile-based intervention application (SPWW) for Korean pregnant women at work and testing its usability and preliminary effects to enhance their self-care practices.

Patients and Methods

The application was developed and tested with thirty-one pregnant women at work and thirteen women's healthcare providers. The instruments used in this study were a modified Health Practices in Pregnancy Questionnaire II and a System Usability Scale. Descriptive analyses and t-tests were performed using SPSS 25.0. The participants' open-ended answers were analyzed using ATLAS. ti 8.

Results

We developed the application focusing on four self-care topics: healthy diet, physical activity, sufficient rest, and stress management. After using the application for two weeks, participants' levels of exercise (p = 0.006), adequate fluid intake (p = 0.002), and limiting daily caffeine intake (p = 0.048) significantly improved. In addition to good usability scores, the suggestions for improvement made by the participants included diversifying the educational materials and adding individually customizable functions to the application.

Conclusion

The application developed in this study enhanced self-care practices of pregnant women at work and showed adequate levels of usability. We expect the developmental process and details of the application provided in this study to serve as a sample guide for future studies.

Associations of objectively measured physical activity and sedentary time with pregnancy-specific health-related quality of life

PURPOSE

To examine associations of objectively measured moderate-to-vigorous-intensity physical activity (MVPA) and sedentary behavior (SED) with pregnancy-specific health-related quality of life (QoL) across pregnancy trimesters.

MATERIALS AND METHODS

Women (N=131, mean age 30.9 years ± 4.9) were recruited from two large health care systems in the United States. MVPA and SED were estimated using a waist-worn ActiGraph GT3X and thigh-worn activPAL3 micro, respectively, for seven days in each trimester of pregnancy. Questionnaires were administered in each trimester to assess pregnancy-specific health-related QoL using the Nausea and Vomiting of Pregnancy Specific health Related Quality of Life (NVPQoL) questionnaire. Mixed effects linear regression examined associations of MVPA and SED with the NVPQoL total score and domain-specific scores (physical symptoms, fatigue, emotions, and limitations) across trimesters.

RESULTS

The NVPQoL total score and domain-specific scores significantly varied across trimesters, with highest scores (indicating worse QoL) observed in the first trimester and lowest scores (indicating better QoL) in the second trimester. A 1-standard deviation (SD) increment in MVPA (16.0 min/day or 1.8%) was associated with better QoL as indicated by the lower NVPQoL total score (β=-4.06, p=0.024) and limitations score (β = -2.80, p<0.001). A 1-SD increment in SED (1.5 hr/day or 10.0%) was associated with worse QoL as indicated by the higher fatigue score (β = 0.82, p=0.041).

CONCLUSIONS

Pregnancy-specific health-related QoL varies across trimesters. Both lower SED, and to a greater extent higher MVPA are potential behavioral targets for improving pregnancy-specific health-related QoL.

Depressive symptoms postpartum is associated with physical activity level the year prior to giving birth - A retrospective observational study

OBJECTIVES

To examine physical activity level prior to pregnancy, during pregnancy and postpartum and investigate the association with depressive symptoms postpartum among women in Sweden.

STUDY DESIGN

Retrospective observational study including 532 women on self-assessment of physical activity level before pregnancy, during pregnancy and postpartum, depressive symptoms postpartum as well as stressful life events in the past two years.

MAIN OUTCOME MEASURES

Level and change of physical activity before pregnancy, during pregnancy and postpartum and depressive symptoms postpartum.

RESULTS

Almost two-thirds of the women in the study reported that they were inactive or performed light physical activity (62.9%; n = 331) in the year prior to giving birth. Women with a sedentary lifestyle or performing light physical activity level reported depressive symptoms postpartum to a greater extent than active women.

CONCLUSIONS

A higher level of physical activity during pregnancy was associated with a lower level of depressive symptoms postpartum. Physical activity is a contributing factor to promote a healthier lifestyle and can contribute to improve mental health for pregnant women, newly become mothers and their children.

Level of exercise and physical activity among pregnant women in Saudi Arabia: A systematic review

The current study aimed to clarify the health benefits of physical activity on the mother and fetus in the Saudi women population. Besides, it is intended to provide recommendation based on the literature and results of studies from Saudi Arabia for exercise in pregnancy to improve the general health of women in Saudi Arabia. Prenatal physical exercise enhances physical and mental health of pregnant women. It can also reduce the risk of multiple pregnancy-related complications such as; lower back pain, fluid retention and risk of gestational diabetes. All these factors can affect fetal development and life later. Multiple studies showed that prenatal exercise could reduce the risk of fetal macrosomia with no effect on other perinatal or postnatal complications. The study followed the systematic literature review approach where it included multiple medical search Databases using PICOS eligibility criteria up to January 2019. The review was based on the following keywords: pregnancy, gestational, or prenatal) and (physical exercise, exercise, or physical activity. There are only two studies that dealt with physical exercises among Saudi women. The results indicated a relation between prenatal physical exercise on improving or decreasing risks on the mother and child during pregnancy.

Effectiveness of Moderate-Intensity Aerobic Water Exercise during Pregnancy on Quality of Life and Postpartum Depression: A Multi-Center, Randomized Controlled Trial

Background: The global prevalence of postpartum depression is about 20%. This disease has serious consequences for women, their infants, and their families. The aim of this randomized clinical trial was to analyze the effectiveness and safety of a moderate-intensity aerobic water exercise program on postpartum depression, sleep problems, and quality of life in women at one month after delivery. Methods: This was a multi-center, parallel, randomized, evaluator blinded, controlled trial in a primary care setting. Pregnant women (14–20 weeks gestational age) who had low risk of complications and were from five primary care centers in the area covered by the obstetrics unit of Son Llatzer Hospital (Mallorca, Spain) were invited to participate. A total of 320 pregnant women were randomly assigned to two groups, an intervention group (moderate aquatic aerobic exercise) and a control group (usual prenatal care). One month after birth, sleep quality (MOS sleep), quality of life (EQ-5D), and presence of anxiety or depression (EPDS) were recorded. Findings: Women in the intervention group were less likely to report anxiety or depression on the EQ5D (11.5% vs. 22.7%; p < 0.05) and had a lower mean EPDS score (6.1 ± 1.9 vs. 6.8 ± 2.4, p < 0.010). The two groups had no significant differences in other outcomes, maternal adverse events, and indicators of the newborn status. Conclusion: Moderate-intensity aquatic exercise during pregnancy decreased postpartum anxiety and depressive symptoms in mothers and was safe for mothers and their newborns.

Usual-Risk Pregnant Women's Health-Related Quality of Life through Pregnancy and Puerperium with Anthroposophical Prenatal Care: A Retrospective Study

INTRODUCTION

Pregnancy is a physiological event that can lead to a decrease in quality of life. Symptoms within this period lack riskless treatment options. However, the anthroposophical integrative view points out the stimulation of vital energy recuperation as a possible inducer of changes in health perception for pregnant women.

OBJECTIVE

The aim was to observe the health-related quality of life variation in women during pregnancy and puerperium. The evaluation was based on the Medical Outcomes Study 36-Item Short-Form (SF-36).

METHOD

This is a retrospective longitudinal study of SF-36 questionnaires administered at 3 different time points: at the first appointment, at an appointment between the 36th ± 1 week of pregnancy and at another appointment within the puerperium period.

RESULTS

Sixty-five patients completed the 3 questionnaires within the period of the study. The 8 domains of SF-36 and women's behaviors throughout the prenatal and puerperal care period were analyzed. Quality of life decreased by the third trimester, with recuperation in the puerperium. Physical components were reduced significantly, while emotional and social components did not change significantly. Scores in mental health and vitality, as well as general health status, were higher in puerperium.

CONCLUSION

Multiprofessional intervention broadened by the anthroposophical perspective fosters the health-related quality of life of women through gestation and puerperium.

Physical Activity Patterns among 9000 Pregnant Women in Poland: A Cross-Sectional Study

The aim was to analyze the knowledge and experience of women regarding physical activity during their latest pregnancy. An anonymous questionnaire was completed electronically, in 2018, by 9345 women who gave birth at least once, with 52% of the women having performed exercises during pregnancy. Physically non-active respondents suffered from gestational hypertension (9.2% vs. 6.7%; p < 0.01) and gave birth prematurely (9% vs. 7%; p < 0.01) to newborns with a low birth weight significantly more often (6% vs. 3.6%; p < 0.001). Physically active women delivered vaginally more often (61% vs. 55%; p < 0.001) and were more likely to have a spontaneous onset of the delivery as compared with non-active women (73.8% vs. 70.7% p = 0.001). The women who were informed by gynaecologist about the beneficial influence of physical activity during pregnancy exercised significantly more often (67% vs. 44% p < 0.001). In addition, 13% of the women felt discrimination due to their physical activity during a pregnancy, 22% of respondents' physical activity was not accepted by their environment, and 39.1% of the women were told by others to stop physical exercise because it was bad for the baby's health. Physical activity during pregnancy is associated with improved fitness, decreased pregnancy ailments occurrence, and therefore influences the course of pregnancy and delivery in a positive way.

Water Exercise and Quality of Life in Pregnancy: A Randomised Clinical Trial

Background: Physical exercise helps to maintain a healthy lifestyle and its practice is recommended for women during pregnancy as a means of limiting the negative effects on the body that may take place and to optimise well-being, mood and sleep patterns, as well as encouraging daily physical activity, enhancing the ability to work and preventing pregnancy-related complications. Aim: To analyse the quality of life in pregnancy for women who complete a programme of moderate physical activity in water, following a designed method that the woman can perform physical exercise safely during pregnancy called the SWEP (study of water exercise during pregnancy) method. Materials and methods: A randomised clinical trial was performed. One hundred and twenty-nine pregnant women were randomly assigned either to an exercise class following the SWEP method (EG, n = 65) or to a control group (CG, n = 64). The trial began in week 20 of pregnancy (May 2016) and ended in week 37 (October 2016). Heath-related quality of life (HRQoL) was evaluated with the SF36v2 health questionnaire at weeks 12 and 35 of pregnancy. Results: The HRQoL score decreased significantly between weeks 12 and 35 of gestation, except for the mental health component, which in the CG fell by -3.28 points and in the EG increased slightly (p > 0.05). Among the CG, the score for the mental health component at week 35 was ≤42, indicating a positive screening risk of depression (39.20 ± 4.16). Conclusions: Physical activity programmes in water, such as SWEP, enhance the HRQoL of pregnant women.

International Fitness Scale-IFIS: Validity and association with health-related quality of life in pregnant women

This study aimed (a) to examine the construct validity of the International Fitness Scale (IFIS) to discriminate between different objectively measured physical fitness levels in pregnant women and (b) to assess the extent to which IFIS is able to discriminate between pregnant women with different levels of health-related quality of life (HRQoL). A total of 159 pregnant women were involved in the GESTAtion and FITness project: 106 pregnant women (mean age 32.7, SD 4.4 years) were included. Self-reported physical fitness-that is, cardiorespiratory fitness, muscular strength, flexibility, and overall fitness-was assessed with the IFIS. Physical fitness was objectively measured using the Bruce test, the handgrip strength test and the back-scratch test. The HRQoL was assessed with the 36-item Short Form Health Survey (SF-36). Higher self-reported physical fitness measured with IFIS was associated with higher objectively measured physical fitness (P < .05). There was a linear association so that higher self-reported physical fitness (ie, IFIS; regardless of the fitness component) was related to greater General Health dimension scores (P < .05). Moreover, higher self-reported physical fitness (all components except muscular strength) was associated with better Physical Functioning, lower Bodily Pain and higher Vitality scores (ie, SF-36 components). This linear trend was not seen for objectively measured physical fitness. The results of this study suggest that IFIS might be a useful tool for identifying pregnant women with low or very low physical fitness and with low quality of life health-related. Further research should elucidate whether IFIS can identify women with pregnancy complications before it can be implemented in clinical practice.

Examination of the Myokine Response in Pregnant and Non-pregnant Women Following an Acute Bout of Moderate-Intensity Walking

Background

It is recommended that women accumulate 150-min of weekly moderate-intensity physical activity (MPA) when pregnant. Engaging in regular physical activity (PA) confers many health benefits to both the mother and the fetus. However, the molecular mechanisms by which these health benefits are bestowed are not well understood. One potential factor that may be contributing to the observed benefits is myokines, which are small peptides secreted by skeletal muscles. In the non-pregnant population, myokines are believed to be involved in the molecular mechanisms resulting from PA. The objective of this study was to characterize and compare the myokine profile of pregnant and non-pregnant women, after an acute bout of MPA.

Methods

Pregnant (n = 13) and non-pregnant (n = 17) women were recruited from the Ottawa region to undergo a treadmill walking session at moderate-intensity (40–60% heart rate reserve). Pre- and post-exercise serum samples were taken, and a set of 15 myokines were analyzed although only 10 were detected. IL-6 was analyzed using a high-sensitivity assay, while FGF21, EPO, BDNF, Fractalkine, IL-15, SPARC, FABP-3, FSTL-1, and oncostatin were analyzed using various multiplex assays.

Results

The pregnant and non-pregnant groups did not differ in terms of age, height, non/pre-pregnancy weight, BMI, and resting heart rate. Baseline levels of EPO and oncostatin were higher in the pregnant group while FGF21 was higher in the non-pregnant group. Circulating levels of three myokines, FGF21, EPO, and IL-15 significantly increased in response to the acute exercise in the pregnant group. Non-pregnant women exhibited an increase in three myokines, FABP-3, FSTL-1, and oncostatin, while one myokine, EPO, decreased post-exercise. SPARC, fractalkine and BDNF were shown to increase post-exercise regardless of pregnancy status while the response for BDNF was more pronounced in the non-pregnant group.

Conclusion

This is the first study examining myokine response following an acute bout of PA in pregnancy. Moderate intensity PA, which is recommended during pregnancy, elicited an increase in four myokines post-compared to pre-exercise in the pregnant group. Further research is warranted to understand the role of myokines in pregnancy.

Health related quality of life (HRQoL) in mothers of premature infants at NICU discharge

BACKGROUND

Premature delivery and a potential Neonatal Intensive Care Unit admission may be associated with the risk of poor maternal health. We aimed to examine the mothers' health-related quality of life (HRQoL) at the time of infant discharge.

STUDY DESIGN

Fifty mothers completed the Medical Outcomes Study-Short Form 12. It has a Physical Component Score (PCS) and Mental Component Score (MCS), both with a mean of 50 and standard deviation of 10. Analysis included infant, maternal, and pregnancy-related characteristics.

RESULTS

In multivariable analyses, a household income of <150K lowered the PCS by 10 points (p = 0.003) compared to those with higher incomes. Marginal significance was noted in GA, for every week gained the PCS score was lower by 1.5 points.

CONCLUSION

Several risk factors are associated with lower physical health ratings in mothers of preterm infants at discharge. This information can be used to inform providers in their anticipatory guidance to the family and follow-up plans.

Effectiveness of Physical Activity Interventions on Pregnancy-Related Outcomes among Pregnant Women: A Systematic Review

Regular physical activity has been demonstrated to contribute to physical and psychological health. Nevertheless, pregnant women generally exhibit low levels of physical activity. Implementation of interventions that enhance the self-efficacy of pregnant women on increasing physical activity is required. This paper provides an in-depth review of studies reporting the effect of various physical activity interventions dedicated for pregnant women on pregnancy-related issues, including gestational weight gain, pain and depression, physical activity level, and quality of life among these individuals. Five databases were used in searching the literature. Findings of the included studies were presented narratively, and appraisal of their methodological quality was conducted using the quality assessment tool developed by Effective Public Health Practice Project. Review findings demonstrated that physical activity interventions are effective in enhancing physical activity levels of pregnant women. Further, they are potentially useful in alleviating pregnancy-related pain and psychological symptoms, reducing gestational weight gain, and increasing self-efficacy in enhancing physical activity levels among these individuals. Nevertheless, inconsistencies in findings between studies hamper the drawing of firm conclusions on these latter outcomes. Overall, studies demonstrated a positive effect of physical activity interventions on the well-being and physical and psychological health of pregnant women.

Structural Equation Modeling on Effects of Community Empowerment and Supplementary Feeding on Health Status and Nutritional Status of Pregnant Women

Introduction: rates of health problems related to a chronic lack of energy in pregnant women in Indonesia remain prevalence. This study aimed to develop community empowerment and supplementary feeding on health status and nutritional status among pregnant women.Methods: the sample included 189 pregnant women living in the six villages in the Jember District. The research used a cluster random sampling technique. The variables included community empowerment, supplementary feeding, health status, and nutritional status of pregnant women. Data analysis was performed using structural equation modeling (SEM) with parameter data estimation using software (Analysis of Moment Structures (AMOS) version 21).Results: estimations of the direct effects were as follows: community empowerment on health status  (0.224), supplementary feeding on health status (0.169), health status on nutritional status of pregnant women (0.001), community empowerment on nutritional status of pregnant women (2.857), supplementary feeding on nutritional status of pregnant women (-0.537), community empowerment on nutritional status of pregnant women through health status (0.000), supplementary feeding on nutritional status of pregnant women through health status (0.000), community empowerment on health status (0.224), supplementary feeding on health status (0.169).Conclusion: community empowerment remains an important key in improving the engagement of women in maternal health issues. Combined intervention with supplementary feeding based on locality may improve the health outcomes.

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.

The association of exercise during pregnancy with trimester-specific and postpartum quality of life and depressive symptoms in a cohort of healthy pregnant women

Few published studies have examined the relationship between exercise during pregnancy, quality of life (QOL), and postpartum depressive symptoms in healthy pregnant women. A prospective cohort of 578 healthy pregnant women were followed during their pregnancy through 6 months postpartum. Levels of self-reported exercise and QOL before, during, and following pregnancy were assessed using standardized questionnaires during each trimester of pregnancy and 6 months postpartum. Depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS) at 28 weeks gestation and 6 weeks postpartum. Participants were classified as having "sufficient exercise" if they achieved at least 150 min of exercise per week. Sufficient exercisers reported significantly higher ratings on most domains of QOL during each trimester of pregnancy and in the postpartum follow-up, compared with insufficient exercisers. There were no significant between-group differences in depressive symptoms. In examining the impact of exercise during each trimester, active women who became sedentary during their third trimester demonstrated a decline in their QOL. Achieving recommended levels of exercise during pregnancy was associated with higher QOL during pregnancy and the postpartum in healthy pregnant women. Decreasing the amount of exercise during pregnancy was associated with reduced QOL. These results suggest that it may be important for health care professionals to counsel healthy pregnant women about both the benefits of being physically active during pregnancy, and to provide guidance on how to remain physically active during a healthy 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.

Benefits of physical activities centered on the trunk for pregnant women

OBJECTIVE

To examine the effect of a trunk exercise program on pain, quality of life (QoL) and physical health (PH) in the late pregnancy and post-partum periods as well as baby weight and size and delivery.

METHODS

90 nulliparous women were allocated based on voluntarism to a training group (TG) or to a control group (CG). TG carried out a structured program with exercises for flexibility, balance and strengthening for the majority of skeletal muscles specifically for the spinal ones, between the 24th and 36th week of pregnancy. Both TG and CG were evaluated for pain at the beginning of the program (T1), at the end of the program (T2) and two months' post-partum (T3). QoL was assessed at T1,T2 and T3, and PH at T1 and T3. Mann-Whitney test was utilized to compare TG and CG on each period and to compare the periods two by two.

RESULTS

At T1, no significant difference was found between the two groups in pain intensity (pain interference p = 0.317), QoL (p = 0.18) and PH (flexibility p = 0.06; walking p = 0.85). At T2, women of TG had a lower intensity of pain than CG (legs (p = 0.029), lower back (p < 0.0001), upper back (p = 0.022), pelvis (p = 0.017), groins (p = 0.043), lower pelvis (p = 0.009) and interference of pain (p < 0.0001)). At T3, TG had a lower intensity of pain than CG, in lower back and upper back (p < 0.0001) and interference of pain (p < 0.0001). Best scores of QoL were observed in TG compared to CG at T2 (p < 0.0001) and at T3 (p < 0.0001). PH in TG compared to CG was not different between the groups in T1 but was different in in T3 (flexibility p = 0.002, walking, balance, curling-ups and Ruffier p < 0.0001). TG were four times less likely to have a caesarean (p = 0.049) and had 4.5 h less of labor time (p < 0.0001). No difference was observed between the TG vs CG concerning the weight (p = 0.22) and the baby's size (p = 0.11).

CONCLUSION

Strengthening exercises centered on the trunk reduce pain, improve QoL and PH in late pregnancy and at two months in the post-partum period. Strengthening exercises also ease the delivery.

Evaluation of the quality of life of pregnant women from 2005 to 2015

Over the past two decades, quality of life has become an essential preoccupation in the care of patients. Many measuring instruments are available to assess physical, psychological and social quality of life. These tools allow healthcare professionals to determine the best quality of their patients. However, the quality of life for the pregnant woman seems to be little studied. This article presents the results of a bibliographic review of publications between 2005 and 2015 - referenced in PUBMED and COCHRANE - on the quality of life of pregnant women giving birth after the 22nd week of amenorrhea. The articles were selected by a reading committee. 195 publications responding to keywords were identified. 75 articles on the problem were selected. The main countries that have published on this subject are Iran (n=11) and Brazil (n=9). France ranks 17th with only one publication. 74% of articles deal with quality of life for pathological pregnancies (gestational or pre-existing pathologies). 23 pathologies were identified, mainly depression (20% of items). This review reveals a growing global interest in quality of life in pregnant women. However, few studies evaluate the impact of care in terms of quality of life in pregnant women, contrary to the recommendations of different health authorities. Finally, the analysis of the various articles shows that, in general, few measurements are made to evaluate the quality of life, not requiring a standardized curve of quality of life during pregnancy. There is thus a significant lack of data to establish a standardized curve for the quality of life of pregnant women, which allows a simple comparison of quality of life measures according to the different clinical management.

Managing Noncommunicable Diseases in an African Community: Effects, Compliance, and Barriers to Participation in a 4-Week Exercise Intervention

To determine the compliance, barriers, and effects of participation in a 4-week exercise intervention aimed at reducing risk factors for noncommunicable diseases among community-dwelling adults from a low-resourced area of South Africa. An exercise program and associated pre-posttest were performed by 76 participants (men, n = 26 and women, n = 50) aged 35 to 65 years. Baseline and end tests included height, weight, hip and waist circumference, heart rate, blood pressure, glucose, cholesterol, quality of life, and cardiorespiratory fitness measurements. The intervention consisted of 3 days/week combined aerobic and resistance exercise at an intensity of 70% heart rate reserved as determined at baseline. Compliance and barriers to participation were determined post-intervention by means of attendance registers and interviews. ANCOVA with adjustment for pretest was performed for all repeated variables. The Cronbach's alpha coefficients for exercise benefits were 0.81 and for barriers 0.84. Of the 26 men (40.8 ± 5.45 years) and 50 women (43.6 ± 7.8 years) recruited, 54 completed the intervention (71% compliance). The 4-week aerobic exercise intervention significantly reduced body mass, rate of perceived exertion, and mental components summary in men, and body mass, body mass index, VO2max, rate of perceived exertion, glucose, physical components summary, and mental components summary in women. Participants reported that the exercise milieu as a major barrier to exercise compliance while the interviews reported lack of time. A 1-month exercise intervention elucidated positive changes in risk factors for noncommunicable diseases in a low-resource community. A drop-out rate of 29% in this study is consistent with other exercise intervention trials. Exploration of the reported barriers may be useful for planning to increase compliance with future programs.

Benefits of aerobic or resistance training during pregnancy on maternal health and perinatal outcomes: A systematic review

OBJECTIVE

To understand what evidence exists with regard to maternal and offspring benefits of aerobic and/or resistance training during pregnancy.

METHODS

Systematic review of RCTs (published until May 2015) with healthy pregnant women and focusing on the benefits of exercise interventions on maternal health or perinatal outcomes. Studies were ranked as high/low quality, and a level of evidence was established according to the number of high-quality studies and consistency of the results.

RESULTS

61 RCTs were analyzed. The evidence for a benefit of combined exercise [aerobic+resistance (muscle strength)] interventions on maternal cardiorespiratory fitness and prevention of urinary incontinence was strong. A weak or insufficient level of evidence was found for the rest of interventions and outcomes

CONCLUSION

The exercise modality that seems to induce a more favorable effect on maternal health is the combination of aerobic and resistance exercises during pregnancy.

Effect of aerobic exercise during pregnancy on antenatal depression

BACKGROUND

Antenatal depression is not uncommon and is associated with a greater risk of negative pregnancy outcomes.

AIM

Exploring the effect of exercise in preventing and treating antenatal depression.

METHODS

This was a prospective interventional controlled study carried out in 100 pregnant women treated at the Ain-Shams Family Medicine Center and Maadi Outpatient Clinic, Cairo, Egypt. The participants were divided into two groups (n=50 in the exercise group and n=50 in the control group). The exercise group regularly attended supervised sessions for 12 weeks. The activities in each session included walking, aerobic exercise, stretching, and relaxation. The control group completed their usual antenatal care. The Center for Epidemiological Studies Depression Scale (CES-D) was used to assess depression symptoms at the first interview and immediately after the 12-week intervention.

RESULTS

Compared to the control group, the exercise group showed significantly improved depressive symptoms as measured with the CES-D after the 12-week intervention on the CES-D (P=0.001). Within groups, the exercise group demonstrated a significant improvement of depressive symptoms from baseline to intervention completion, while the control group demonstrated no significant changes over time.

CONCLUSION

Exercise during pregnancy was positively associated with reduced depressive symptoms.

Physical activity and health-related quality of life during pregnancy: a secondary analysis of a cluster-randomised trial

The aim of the study was to evaluate the role of physical activity before and during pregnancy on health-related quality of life (HRQoL). Data from the cluster-randomised gestational diabetes mellitus primary prevention trial conducted in maternity clinics were utilised in a secondary analysis. The cases considered were pregnant women who reported engaging in at least 150 min of moderate-intensity leisure-time physical activity per week (active women) (N = 80), and the controls were women below these recommendations (less active) (N = 258). All participants had at least one risk factor for gestational diabetes mellitus. Their HRQoL was evaluated via the validated generic instrument 15D, with HRQoL at the end of pregnancy examined in relation to changes in physical activity during pregnancy. Logistic regression models addressed age, parity, education, and pre-pregnancy body mass index. At the end of pregnancy, the expected HRQoL was higher (tobit regression coefficient 0.022, 95 % CI 0.003-0.042) among active women than less active women. Active women also had greater mobility (OR 1.98, 95 % CI 1.04-3.78), ability to handle their usual activities (OR 2.22, 95 % CI 1.29-3.81), and vitality (OR 2.08, 95 % CI 1.22-3.54) than did less active women. Active women reported higher-quality sleep (OR 2.11, 95 % CI 1.03-4.30) throughout pregnancy as compared to less active women. Meeting of the physical activity guidelines before pregnancy was associated with better overall HRQoL and components thereof related to physical activity.

What is the effect of regular group exercise on maternal psychological outcomes and common pregnancy complaints? An assessor blinded RCT

OBJECTIVE

to examine the effects of supervised group exercise on maternal psychological outcomes and commonly reported pregnancy complaints.

DESIGN

an observer-blinded randomized controlled trial.

SETTING

Norwegian School of Sport Sciences, Oslo, Norway.

PARTICIPANTS

105 sedentary, nulliparous pregnant women, mean age 30.7(± 4.0) years, pre-pregnancy BMI 23.8 (± 4.3), were assigned to either exercise (n=52) or control group (n= 53) at mean gestation week 17.7 (± 4.2).

INTERVENTION

the exercise intervention followed ACOG guidelines and included a 60 minutes general fitness class, with 40 minutes of endurance training/aerobic and 20 minutes of strength training and stretching/relaxation, performed at least twice per week for a minimum of 12 weeks.

MEASUREMENTS

outcome measures were assessed through standardized interviews pre- and post-intervention (gestation week 36.6, ± 0.9), and included psychological variables related to quality of life, well-being, body image and pregnancy depression, as well as assessment of 13 commonly reported pregnancy complaints.

FINDINGS

post-intervention, using intention to treat (ITT) analysis, women randomized to exercise rated their health significantly better compared to women in the control group (p=0.02) and reported less fatigue related to everyday activities (p=0.04). Women with complete exercise adherence (≥ 24 sessions) had significantly better scores on measurements of feelings related to sadness, hopelessness and anxiety (p<0.01), compared to the control group. Contradictory, the control group reported higher life enjoyment (p<0.01). There were no significant group differences in body-image or pregnancy depression. With respect to analysing pregnancy complaints according to ITT, no differences between the groups were found. A comparison of the women who attended ≥ 19 (80%, n=21) or ≥ 24 (100%, n=14) exercise sessions with the control-participants, showed that fewer women in the exercise group reported nausea/vomiting and numbness/poor circulation in legs. KEY CONCLUSION AND IMPLICATION FOR PRACTISE: participation in regular group exercise during pregnancy contributed to improvements in some variables related to maternal well-being and quality of life. Women with high exercise adherence had significantly better results on several health variables reaping the highest benefits. A qualitative study exploring the barriers of women in achieving recommended amount of activity may be necessary to understand this population and developing better clinical practice educational tools.

A comparison of a social support physical activity intervention in weight management among post-partum Latinas

BACKGROUND

Weight gain during the childbearing years and failure to lose pregnancy weight after birth contribute to the development of obesity in postpartum Latinas.

METHODS

Madres para la Salud [Mothers for Health] was a 12-month, randomized controlled trial exploring a social support intervention with moderate-intensity physical activity (PA) seeking to effect changes in body fat, fat tissue inflammation, and depression symptoms in sedentary postpartum Latinas. This report describes the efficacy of the Madres intervention.

RESULTS

The results show that while social support increased during the active intervention delivery, it declined to pre-intervention levels by the end of the intervention. There were significant achievements in aerobic and total steps across the 12 months of the intervention, and declines in body adiposity assessed with bioelectric impedance.

CONCLUSIONS

Social support from family and friends mediated increases in aerobic PA resulting in decrease in percent body fat.

Influence of a medium-impact exercise program on health-related quality of life and cardiorespiratory fitness in females with subclinical hypothyroidism: an open-label pilot study

Objective. To examine the influence of a medium-impact exercise program (MIEP) on health-related quality of life (HRQoL) and cardiorespiratory fitness (VO_2max) in females with subclinical hypothyroidism (sHT). Materials and Methods. We selected 17 sedentary women with sHT (mean age: 43.1 (standard deviation: 9.7) years). Participants carried out an MIEP consisting of 3 weekly sessions of 60 minutes during 12 weeks. Before and after the exercise program HRQoL was assessed by the SF-12v2 questionnaire, and VO_2max was evaluated by Rockport walk test. Results. After the 12-week intervention, the participants that performed an MIEP showed improvements in HRQoL in most domains, particularly the vitality domain by 7 points, the social functioning domain by 10 points, the mental health domain by 7 points, and the mental component summary by 7 points. One of the four domains within the physical component summary (general health domain) showed significant effect of the exercise intervention: 6 points. Moreover, the participants that performed exercise showed a higher VO_2max (28%; P < 0.01). Conclusion. After 12 weeks of medium-impact exercise program, there were remarkable improvements in HRQoL in most domains. Moreover, this exercise program proved to have a positive influence on cardiorespiratory fitness.

A Systematic Review of Quality of Life Measures in Pregnant and Postpartum Mothers

Quality of life has emerged as an essential health component that broadens the traditionally narrow concerns focused on only morbidity and life expectancy. Although a growing number of tools to measure quality of life are in circulation, there is a lack of guidelines as well as rigorous assessment for their use with pregnant and postpartum populations. It is also unclear whether these instruments could validly be employed to measure patient-reported outcomes in comparative effectiveness research of maternal care interventions. This paper reviews articles cited in CINAHL, COCHRANE, EMBASE, PSYCINFO, and PUBMED that addressed quality of life in pregnant and postpartum populations. Instruments used to measure quality of life in selected articles were assessed for their adherence to international guidelines for health outcomes instrument development and validation. The authors identified 129 articles that addressed quality of life in pregnant and/or postpartum women. Out of these, only 64 quality (generic and specific) scales were judged relevant to be included in this study. Analysis of measurement scales used in the pregnant and/or postpartum populations revealed important validity, reliability and psychometric inadequacies that negate their use in comparative effectiveness analysis in pregnant and post-partum populations. Valid, reliable, and responsive instruments to measure patient-reported outcomes in pregnant and postpartum populations are lacking. To demonstrate the effectiveness of various treatment and prevention programs, future research to develop and validate a robust and responsive quality of life measurement scale in pregnant and postpartum populations is needed.

Benefits of exercise during pregnancy

There is a direct link between healthy mothers and healthy infants. Exercise and appropriate nutrition are important contributors to maternal physical and psychological health. The benefits and potential risks of exercise during pregnancy have gained even more attention, with a number of studies having been published after the 2002 American College of Obstetrics and Gynecologists guidelines. A review of the literature was conducted by using PubMed, Scopus, and Embase to assess the literature regarding the benefits of exercise during pregnancy. The search revealed 219 publications, which the authors then narrowed to 125 publications. The purpose of this review is to briefly summarize the known benefits of exercise to the mother, fetus, and newborn.

Stages of change model for participation in physical activity during pregnancy

Background. The transtheoretical model (TTM) has been successful in promoting health behavioral change in the general population. However, there is a scant knowledge about physical activity in relation to the TTM during pregnancy. Hence, the aims of the present study were (1) to assess readiness to become or stay physically active according to the TTM and (2) to compare background and health variables across the TTM. Methods. Healthy pregnant women (n = 467) were allocated to the study from Oslo University Hospital, Norway. The participants filled in a validated self-administered questionnaire, physical activity pregnancy questionnaire (PAPQ) in gestation, weeks 32–36. The questionnaire contained 53 questions with one particular question addressing the TTM and the five stages: (1) precontemplation stage, (2) contemplation stage, (3) preparation stage, (4) action stage, and (5) maintenance stage. Results. More than half of the participants (53%) were involved in regular exercise (stages 4-5); however, only six specified that they had recently started an exercise program (stage 4). About 33% reported engaging in some physical activity, but not regularly (stage 3). The results showed that receiving advice from health professionals to exercise during pregnancy increased the likeliness of being in stages 4-5, while higher age, multiparity, pregravid overweight, unhealthy eating habits, pelvic girdle pain, and urinary incontinence were more prevalent with low readiness to change exercise habits (stages 1–3). Conclusion. According to the TTM, more than half of the participants reported to be physically active. Moreover, most of the participants classified as inactive showed a high motivational readiness or intention to increase their physical activity level. Hence, pregnancy may be a window of opportunity for the establishment of long-term physical activity habits.

The effect of maternal stress and health-related quality of life on birth outcomes among Macao Chinese pregnant women

This study investigated the prevalence of preterm birth and low-birth-weight in Macao. It also evaluated the effects of maternal perceived stress and health-related quality of life on these 2 birth outcomes. A quantitative study using a prospective longitudinal design was undertaken in an antenatal clinic in Macao. A community-based sample (N = 581) of pregnant women in their second trimester was recruited; birth outcome data were collected from medical records. Perceived stress was measured using the Perceived Stress Scale, whereas health-related quality of life was measured using the standard SF-12 Health Survey. The prevalence rates of preterm birth and low-birth-weight were found to be 6.4% and 7.1%, respectively. Two multiple logistic regression analyses revealed that participants with past adverse obstetric complications and higher perceived stress levels were more likely to have premature infants. Also, those participants with higher perceived stress levels and poorer health-related quality of life in the physical health domain were more likely to have low-birth-weight infants. Preliminary information was provided on risk factors associated with adverse birth outcomes; this could help nurses to design appropriate risk-specific interventions for preventing preterm birth and low-birth-weight.

Overweight, obesity, and neighborhood characteristics among postpartum Latinas

BACKGROUND

Weight gain during the childbearing years and failure to lose pregnancy weight after birth contribute to the development of obesity in Latinas.

DESIGN AND METHODS

Madres para la Salud (Mothers for Health) is a 12-month prospective, randomized controlled trial exploring a social support intervention with moderate-intensity physical activity to effect changes in body fat, systemic and fat tissue inflammation, and depression symptoms in sedentary postpartum Latinas. This paper describes the initial body composition of the sample, social support, and neighborhood contextual correlations of overweight and obese Latina mothers within the first 6 months after birth.

RESULTS

The mean body mass index was 29.68 with 38.56% bioelectrical impedence analysis for body fat. Elements of the environment (e.g., opportunities to walk) received middle or high scores. Access to healthy food was positively related to favorability of the walking environment. Waist-to-hip ratio was uncorrelated with other obesity-related indices.

CONCLUSIONS

The body adiposity of these Latina mothers was coupled with low levels of social support from family and friends and neighborhood characteristics that were unfavorable to walking.

Aerobic exercise training during pregnancy reduces depressive symptoms in nulliparous women: a randomised trial

QUESTION

Does supervised aerobic exercise during pregnancy reduce depressive symptoms in nulliparous women?

DESIGN

Randomised trial with concealed allocation, blinded assessors, and intention-to-treat analysis.

PARTICIPANTS

80 nulliparous, pregnant women attending for prenatal care at one of three tertiary hospitals in Cali, Colombia.

INTERVENTION

The experimental group completed a 3-month supervised exercise program, commencing at 16 to 20 weeks of gestation. Each session included walking (10 min), aerobic exercise (30 min), stretching (10 min), and relaxation (10 min). The control group continued usual activities and performed no specific exercise.

OUTCOME MEASURES

The primary outcome was symptoms of depression assessed by the Center for Epidemiological Studies Depression Scale (CES-D) at baseline and immediately after the 3-month intervention.

RESULTS

74 women completed the study. After the 3-month intervention, the experimental group reduced their depressive symptoms on the CES-D questionnaire by 4 points (95% CI 1 to 7) more than the control group.

CONCLUSIONS

A supervised 3-month program of primarily aerobic exercise during pregnancy reduces depressive symptoms.
