Hemodynamic, ventilatory and gas exchange responses to exercise using a cycle ergometer and the incremental shuttle walk test in pregnant women

BACKGROUND

Cardiovascular disease, including hypertension, in pregnant women is a leading cause of morbidity and mortality globally. The development of reference intervals for cardiovascular responses using exercising testing to measure oxygen utilisation (V̇O2) with cardiopulmonary exercise testing (CPET), and distances walked using the incremental shuttle walk test (ISWT), may be promising methods to assess and stratify pregnant women regarding their risk of adverse pregnancy outcomes, to encourage exercise during pregnancy, and to improve exercise prescriptions during pregnancy. We aimed to determine the reference intervals for V̇O2 at rest, anaerobic threshold (AT), and submaximal exercise using CPET, and the reference interval for the ISWT, to develop a correlation equitation that predicts submaximal V̇O2 from the distance walked in the ISWT, and to explore the relationship between hemoglobin (Hb) and ferritin concentration and V̇O2 at AT in women in second trimester.

METHODS

After prospective IRB approval (HREC 15/23) and clinical trials registration (ANZCTR ACTRN12615000964516), and informed written consent, we conducted CPET and the ISWT according to international guidelines in a university associated tertiary referral obstetric and adult medicine hospital, in healthy pregnant women in second trimester (14 to 27 gestational weeks). Hemoglobin and ferritin concentrations were recorded from pathology results in the participants' medical records at the time of exercise testing. Adverse events were recorded.

RESULTS

About 90 participants undertook CPET, 28 of which also completed the ISWT. The mean ± SD age and body mass index (BMI) were 32 ± 3.2 years, and 25 ± 2.7 kg/m2. Median (IQR) gestation was 23 (22-24) weeks. One in 4 women were 24 weeks or greater gestation. The reference intervals for V̇O2 at rest, AT, and submaximal exercise were 2.9 to 5.3, 8.1 to 20.7, and 14.1 to 30.5 mL/kg/min respectively. The reference interval for the ISWT was 218 to 1058 meters. The correlation equation to predict submaximal V̇O2 from the distance walked in the ISWT was submaximal V̇O2 (mL/kg/min) = 0.012*distance walked in ISWT (m) + 14.7 (95%CI slope 0.005-0.070, Pearson r = 0.5426 95%CI 0.2126-0.7615, P = .0029). Hemoglobin concentration was positively correlated with V̇O2 at AT (AT V̇O2 (mL/kg/min) = 0.08*Hb (g/L) + 4.9 (95%CI slope 0.0791-0.143, Pearson r = 0.2538 95%CI 0.049-0.438, P = .016). There was no linear association between ferritin and submaximal V̇O2 (Pearson r = 0.431 P = .697). There were no maternal or fetal complications.

CONCLUSIONS

CPET and ISWT are safe and feasible in women in second trimester including those at or beyond 24 weeks gestation. We have established the reference interval for V̇O2 at rest, AT, and submaximal exercise by CPET, the reference interval for the distance walked for the ISWT, and a correlation equation to predict submaximal V̇O2 for use in clinical practice and research. Hemoglobin rather than ferritin is likely correlated with exercise capacity in pregnancy suggesting vigilance to correct lower hemoglobin levels may positively impact maternal health.

Prevalence and Risk Factors for Musculoskeletal Pain when Running During Pregnancy: A Survey of 3102 Women

BACKGROUND

Musculoskeletal pain while running is a concern to women during pregnancy and can lead to running cessation. To support women who wish to run during pregnancy, it is essential to understand the sites, severities and personal risk factors associated with musculoskeletal pain.

OBJECTIVE

The aim was to investigate prevalence and risk factors for musculoskeletal pain when running during pregnancy.

METHODS

An online survey was completed by women who had a child in the past 5 years and ran prior to and during pregnancy. Pain frequency informed prevalence rates by body site, and logistic regression odds ratios (ORs) and 95% confidence intervals were calculated.

RESULTS

A total of 3102 women of 23 ethnicities from 25 countries completed the survey. Women were 22-52 years old when they gave birth and ran 2-129 km/week during the 0.5-35 years before the birth of their youngest child. Women ran significantly less distance and less often during pregnancy than before pregnancy. Most women (86%) experienced pain while running during pregnancy (59% pelvis/sacroiliac joint, 52% lower back, 51% abdomen, 44% breast, 40% hip). The highest prevalence of severe-to-worst pain was at the pelvis/sacroiliac joint (9%). Women at greatest risk of pain while running during pregnancy had a previous injury (OR = 3.44) or were older (OR = 1.04). Women with a previous child were less likely to experience breast pain (OR = 0.76) than those running during their first pregnancy.

CONCLUSION

Healthcare practices to reduce pain should focus on regions of greatest musculoskeletal change during pregnancy, specifically the pelvis, lower back and abdomen. Efforts to support women to run for longer throughout pregnancy should focus on pain at the pelvis and breasts.

Physical Activity in Work and Leisure Time during Pregnancy, and Its Influence on Maternal Health and Perinatal Outcomes

BACKGROUND

Physical inactivity during pregnancy has been shown to be linked to an increased risk of complications. However, during pregnancy, doubts arise about what type, intensity and frequency of physical activity are most recommended.

OBJECTIVE

Our main objective was to know the level of physical activity (PA) and sedentary lifestyle in a representative sample of pregnant women in Málaga, one of the most populated cities in Spain. Also, we aimed to find out the effects of PA on obstetric and perinatal outcomes and on the mental health of pregnant women, differentiated according to PA intensity and domain.

METHODS

Five hundred and forty full-term pregnant women who had their obstetric checks in the maternity ward of the Regional University Hospital of Málaga were recruited through consecutive sampling. Participants answered a questionnaire that included the WHO Global Physical Activity Questionnaire (GPAQ), the Edinburgh Depression Scale (EDS), the Generalized Anxiety Disorder Scale (GAD-7) and some other sociodemographic and health-related questions. Subsequently, information about perinatal outcomes was obtained after birth.

RESULTS

Only 50.8% of women followed the WHO recommendations on activity. We found a high proportion of obese pregnant women and a direct effect of a sedentary lifestyle on the rate of cesarean sections and vulvovaginal tears in spontaneous births, as well as on the mental health of future mothers. Women's age, the number of children, BMI at the beginning of pregnancy and leisure time physical activity (LTPA) explained anxiety scores, and age, LTPA, BMI at the end of pregnancy and intense work-related physical activity (WTPA) predicted depression scores.

CONCLUSIONS

LTPA improves obstetric outcomes, helping to reduce the rate of cesarean sections and vulvovaginal tears, as well as reducing prenatal anxiety and depression.

A review of public health guidelines for postpartum physical activity and sedentary behavior from around the world

BACKGROUND

The period following pregnancy is a critical time window when future habits with respect to physical activity (PA) and sedentary behavior (SB) are established; therefore, it warrants guidance. The purpose of this scoping review was to summarize public health-oriented country-specific postpartum PA and SB guidelines worldwide.

METHODS

To identify guidelines published since 2010, we performed a (a) systematic search of 4 databases (CINAHL, Global Health, PubMed, and SPORTDiscus), (b) structured repeatable web-based search separately for 194 countries, and (c) separate web-based search. Only the most recent guideline was included for each country.

RESULTS

We identified 22 countries with public health-oriented postpartum guidelines for PA and 11 countries with SB guidelines. The continents with guidelines included Europe (n = 12), Asia (n = 5), Oceania (n = 2), Africa (n = 1), North America (n = 1), and South America (n = 1). The most common benefits recorded for PA included weight control/management (n = 10), reducing the risk of postpartum depression or depressive symptoms (n = 9), and improving mood/well-being (n = 8). Postpartum guidelines specified exercises to engage in, including pelvic floor exercises (n = 17); muscle strengthening, weight training, or resistance exercises (n = 13); aerobics/general aerobic activity (n = 13); walking (n = 11); cycling (n = 9); and swimming (n = 9). Eleven guidelines remarked on the interaction between PA and breastfeeding; several guidelines stated that PA did not impact breast milk quantity (n = 7), breast milk quality (n = 6), or infant growth (n = 3). For SB, suggestions included limiting long-term sitting and interrupting sitting with PA.

CONCLUSION

Country-specific postpartum guidelines for PA and SB can help promote healthy behaviors using a culturally appropriate context while providing specific guidance to public health practitioners.

Effectiveness of exercise interventions on urinary incontinence and pelvic organ prolapse in pregnant and postpartum women: umbrella review and clinical guideline development

INTRODUCTION AND AIMS

Dysfunction related to pelvic floor muscles (PFM) is common among pregnant and postpartum women and can cause symptoms such as urinary incontinence or pelvic organ prolapse (POP). As part of developing a nationwide clinical practice guideline for nursing in Finland, the aim of this umbrella review is to summarize the existing evidence about the effectiveness of exercise interventions on urinary incontinence and POP in pregnant and postpartum women. To promote knowledge translation, recommendations for health care professionals are presented.

METHODS

We conducted an umbrella review to summarize the existing evidence. The JBI methodology for umbrella reviews was used to guide the review. The level of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, and recommendations based on the evidence were formulated by a clinical guideline working group.

RESULTS

Altogether, 9 systematic reviews, reporting findings from 89 original studies, were included. The methodological quality of the reviews was evaluated using JBI's checklist. The highest level of evidence was found for preventing the symptoms of postpartum urinary incontinence through exercise and pelvic floor muscle training (PFMT) during pregnancy. Moderate-level evidence showed that exercise and PFMT are likely to reduce the symptoms and severity of urinary incontinence, but the level of evidence was low on PFMT reducing the symptoms of POP.

CONCLUSION

We recommend encouraging and guiding pregnant and postpartum women to exercise and train PFM. We also recommend identifying pregnant and postpartum women with symptoms of PFM dysfunction and directing them to a physiotherapist or other health care professional specializing in pelvic floor function.

Navigating the 'new normal': what guidelines exist for postpartum return to physical activity and sport? A scoping review

OBJECTIVE

Women are often advised to return to activity (RTA) as early as 6 weeks postpartum, despite undergoing significant physical, physiological and psychological changes. Our objective was to examine existing evidence and clinical practice guidelines to navigate a safe and successful RTA or return to sport (RTS) postpartum.

METHODS

We searched CINAHL, Embase, Medline, PsycINFO and SPORTDiscus and included any secondary studies with recommendations or guidelines for RTA or RTS postpartum. Grey literature and primary sources were excluded. Four reviewers independently screened titles and abstracts, followed by full-text review for eligibility, with conflicts resolved by a third-party reviewer. One reviewer extracted data, which was cross-referenced by another reviewer.

RESULTS

5851 studies were screened, and 33 were included in this scoping review. Most studies stated that RTS postpartum can begin once 'medically safe', around 6 weeks postpartum, but this term was generally left undefined. In addition, most studies recommended engaging in 150 min of moderate-vigorous physical activity per week after 6 weeks postpartum, but the type of exercise recommended was often non-specific.

CONCLUSION

A lack of consistent, evidence-based guidelines exist for RTA or RTS postpartum. Multiple evidence gaps require additional research to inform patient and activity specific guidelines for a safe and successful RTA or RTS postpartum.

Attitudes and Barriers to Physical Activity and Exercise Self-Efficacy Among Chinese Pregnant Women: A Cross-Sectional Study

Background

Most pregnant women do not reach the recommendation for physical activity (PA). As a subcategory of PA, exercise is also essential. Evidence on pregnant women's attitudes and barriers to PA and exercise self-efficacy in China is scarce.

Aim

To explore the levels and influencing factors of attitudes and barriers to PA and exercise self-efficacy among pregnant women.

Methods

A cross-sectional study of 311 pregnant women was conducted from August to December 2022. Individual characteristics, pregnant women's attitudes toward exercise, barriers to prenatal PA and exercise, and exercise self-efficacy were measured using the self-designed demographic questionnaire, pregnant women's attitudes toward exercise questionnaire, barriers to prenatal PA and exercise questionnaire, and the pregnancy exercise self-efficacy scale, respectively.

Results

More than 90% of pregnant women believed exercise benefits themselves and their babies, and 40.8% of pregnant women did not know how to exercise. Women encounter different types of barriers to PA and exercise. Intrapersonal barriers included the proportion of feelings of tiredness (56.6%), low energy (54.7%), lack of interest or motivation (49.2%), feelings of illness and morning sickness (46.6%), and large body weight (43.7%). Interpersonal barriers included pregnant women being advised to avoid PA and exercise (49.2%), lack of clear advice about the intensity and dose of exercise (41.8%), no one to exercise with (38.9%), and lack of advice from healthcare professionals (38.6%). Weather conditions were the most significant environmental barriers (41.2%). The total score of pregnancy exercise self-efficacy was (38.50±7.33). Education level, parity, and attitudes toward exercise independently predict pregnant women's attitudes toward exercise, barriers to prenatal PA and exercise, and exercise self-efficacy, respectively.

Conclusion

Pregnant women have a favorable attitude toward exercise and relatively good exercise self-efficacy but lack knowledge of exercise. They face numerous barriers. Medical professionals should encourage pregnant women with lower levels of education to exercise and assist multipara in overcoming obstacles.

Maternal postnatal confinement practices and postpartum depression in Chinese populations: A systematic review

BACKGROUND

The postpartum period is critical for maternal health status after childbirth. The traditional Chinese postpartum confinement practice, "doing-the-month", is considered especially effective in helping mothers recover during the postpartum period. However, research has not provided evidence to confirm its benefits. Postpartum depression is a common postpartum disease that seriously threatens maternal health. The systematic review aims to explore the association between "doing-the-month" and postpartum depression in the Chinese female population and to provide a scientific foundation for evidence-based postpartum maternal care.

METHODS

Five databases (PubMed, Embase, Web of Science, Scopus, Cochrane, PsycINFO, and Web of Science) were searched according to the protocol (INPALSY202320102). The JBI assessment tool was used to assess the quality of the included studies.

RESULTS

Sixteen quantitative studies from China and Chinese female immigrants in other countries, including 15 cross-sectional studies and 1 randomized controlled study, were identified. Four studies indicated that "doing-the-month" rituals reduced postpartum depression risk while 2 studies showed opposite results; 10 studies did not show a significant association between "doing-the-month" practices and postpartum depression.

CONCLUSION

There is conflicting evidence regarding the association between "doing-the-month" and the likelihood of developing postpartum depression. Some studies have explored the impact of family ties, particular rituals, and specific stressors during the postpartum period on the occurrence of postpartum depression in Chinese women. According to current research, "doing-the-month" practice failed to show a significant protective effect on postpartum depression in the Chinese maternal population. Evidence-based medical health education for the Chinese postpartum female community is urgently needed.

Feasibility of a Supervised Postpartum Exercise Program and Effects on Maternal Health and Fitness Parameters-Pilot Study

The postpartum period is marked by profound changes in women at physical, psychological, and physiological levels. Many of these changes persist after four to six weeks postpartum, and most women do not resume their levels of physical activity, which increases the risk of remaining inactive for many years. It is crucial to implement effective programs that promote exercise during the postpartum period. The objective of this study was to test the feasibility and analyze the effects of a structured and supervised postpartum exercise program on maternal health and fitness parameters. To analyze the potential effects of the intervention, the level of physical activity, quality of life, pelvic girdle and low back pain, fatigue, depression, and the level of functional and physical fitness were assessed at baseline, after 8 weeks, and after 16 weeks of intervention. Feedback on the exercise program was collected after the final assessment. The results showed that a structured and supervised postpartum exercise program was feasible and safe and produced positive effects on selected maternal health and fitness parameters. These results will encourage a study protocol with a larger sample in order to prove its effectiveness, improve the guidelines for postpartum exercise, and incorporate this program into a routine healthcare setting.

Standardized Stretching Postural postures to treat low-back pain in pregnancy: the GEMALODO randomized clinical trial

BACKGROUND

Two-thirds of pregnant women suffer from low-back pain during pregnancy, which leads to negative effects on quality of everyday life. According to the literature, an 8- to 12-week program of adapted physical activity during pregnancy has proven its efficacy in treatment of low-back pain and functional disability. Stretching Postural is a nondynamic technique using muscular contractions and stretches that act mainly on the back and that can be practiced alone.

OBJECTIVE

This study aimed to assess the effect of an 8-week program of standardized Stretching Postural postures in low-risk pregnant women suffering from low-back pain.

STUDY DESIGN

This was an open-label, randomized, controlled trial in 1 French university hospital. Women with a singleton low-risk pregnancy between 15 and 32 weeks of gestation and with back, lumbar, or sacroiliac pain were randomly assigned (1:1) to either undergo an 8-week program of standardized Stretching Postural with basic advice (intervention group) or to receive basic advice only (control group). Both groups received ergonomic advice and encouragement to practice physical activity. The primary endpoint was the pain assessment at 8 weeks (defined by the mean pain level estimated by women in the previous week, scored on a numeric scale from 0 to 10). Secondary endpoints were pain after 4 weeks of follow-up, quality of life (12-item Short Form Survey), satisfaction (Patient Global Impression of Change), and delivery outcomes. The main analysis was intention-to-treat.

RESULTS

From January 2019 to August 2020, 60 women were randomized: 30 were assigned to the intervention group and 30 to the control group. The mean level of pain at 8 weeks was significantly lower in the intervention group than in the control group (1.6±1.4 vs 4.1±2.2; P<.01). The mean 12-item Short Form Survey scores were significantly higher in the posture group than in the control group (Physical Component Score, 45.7±7.8 vs 37.4±8.5; P<.01; Mental Component Score, 54.3±5.8 vs 50.4±7.1; P=.04), and the Patient Global Impression of Change score was also significantly higher (6.1±1.5 vs 3.9±2.3; P<.01). No adverse effects were found.

CONCLUSION

Stretching Postural appears to be a safe and efficient nondrug therapy to treat low-back pain during low-risk pregnancy.

Physical Activity Accumulated Across Adulthood and Resting Heart Rate at Age 41-46 Years in Women: Findings From the Menarche to Premenopause Study

OBJECTIVE

To investigate the association between physical activity accumulated from early (age 22-27 y) to mid (age 40-45 y) adulthood and resting heart rate at age 41-46 years in women.

METHODS

Data were from 479 participants in the 1973-1978 cohort of the Australian Longitudinal Study on Women's Health. Participants reported physical activity every 3 years from age 22-27 years to 40-45 years. Linear regression models were used to investigate the associations of a cumulative physical activity score (average physical activity across 18 y; up to 7 surveys) and changes in physical activity from age 22-33 years to 34-45 years with resting heart rate at age 41-46 years.

RESULTS

Average resting heart rate at age 41-46 years was 75 (SD: 11) beats per minute. An inverse nonlinear dose-response association between cumulative physical activity and resting heart rate was observed. Overall, accumulation of physical activity was associated with lower resting heart rate regardless of the age when physical activity was accumulated. Women in the highest tertile of physical activity at both age 22-33 years and 34-45 years had a resting heart rate, on average, 8 beats per minute lower (95% confidence interval, -11.42 to -4.69) than those consistently in the lowest tertile of physical activity.

CONCLUSION

Accumulating physical activity, irrespective of timing, appears to provide cardiovascular health benefits for women before the transition to menopause.

Public health guidelines for physical activity during pregnancy from around the world: a scoping review

BACKGROUND AND OBJECTIVE

Despite the known health benefits of physical activity (PA), pregnancy is a time of marked decline in PA levels. To provide women with reliable and trustworthy information, and to encourage greater participation in PA during pregnancy, many governments have developed guidelines for PA during pregnancy. Our aim was to synthesise the most recent public health guidelines on PA during pregnancy from different countries in order to understand the nature and extent of advice that is available.

DESIGN

Scoping review.

DATA SOURCES

Search of the grey literature, direct contact with international experts, screening of relevant academic literature and citation searching.

ELIGIBILITY CRITERIA

Public health guidelines developed or endorsed by government departments published since 2010.

RESULTS

Our search located 30 eligible guidelines, published in 11 different languages. There is remarkable concordance in the advice offered. For women with uncomplicated pregnancy, guidelines recommend: 150-300 min/week of moderate intensity aerobic activity; pelvic floor and muscle strengthening exercises; modification of some exercises (eg, supine position); and provide lists of warning signs to cease activity (eg, persistent dizziness, vaginal bleeding) and activities that should be avoided (eg, if high risk of falling/collision). Few guidelines offer specific advice for highly active women (eg, athletes), or trimester-specific or culturally specific considerations.

CONCLUSIONS

This review provides a summary of public health recommendations for PA during pregnancy around the world. The challenge is now to ensure that all who provide healthcare for women understand the guidelines and encourage safe participation in PA during pregnancy.

A mixed-methods exploration of attitudes towards pregnant Facebook fitness influencers

BACKGROUND

Exercise during pregnancy is associated with various health benefits for both mother and child. Despite these benefits, most pregnant women do not meet physical activity recommendations. A known barrier to engaging in exercise during pregnancy is a lack of knowledge about appropriate and safe exercise. In our current era of social media, many pregnant women are turning to online information sources for guidance, including social media influencers. Little is known about attitudes towards pregnancy exercise information provided by influencers on social media platforms. This study aimed to explore attitudes towards exercise during pregnancy depicted by social media influencers on Facebook, and user engagement with posted content.

METHODS

A mixed-methods approach was used to analyse data from 10 Facebook video posts of social media influencers exercising during pregnancy. Quantitative descriptive analyses were used to report the number of views, shares, comments and emotive reactions. Qualitative analysis of user comments was achieved using an inductive thematic approach.

RESULTS

The 10 video posts analysed were viewed a total of 12,117,200 times, shared on 11,181 occasions, included 13,455 user comments and 128,804 emotive icon reactions, with the most frequently used icon being 'like' (81.48%). The thematic analysis identified three themes associated with attitudes including [1] exercise during pregnancy [2] influencers and [3] type of exercise. A fourth theme of community was also identified. Most user comments were associated with positive attitudes towards exercise during pregnancy and the influencer. However, attitudes towards the types of exercise the influencer performed were mixed (aerobic and body weight exercises were positive; resistance-based exercise with weights were negative). Finally, the online community perceived by users was mostly positive and recognised for offering social support and guidance.

CONCLUSIONS

User comments imply resistance-based exercise with weights as unsafe and unnecessary when pregnant, a perception that does not align with current best practice guidelines. Collectively, the findings from this study highlight the need for continued education regarding exercise during pregnancy and the potential for social media influencers to disseminate evidence-based material to pregnant women who are highly receptive to, and in need of reliable health information.

[Practical recommendations on physical exercise during pregnancy based on the main clinical practice guidelines]

The main guidelines for physical activity/exercise during pregnancy recommend that all pregnant women without medical or obstetric contraindications remain physically active during pregnancy, in order to achieve health benefits and, at the same time, reduce the possibility of complications during pregnancy. The objective of this article was to extract the practical recommendations on physical exercise during pregnancy, of interest to the primary care physician, from the clinical practice guidelines of three international societies of Obstetrics and Gynecology of recognized prestige and great international influence on this subject, two of them pioneers in the elaboration of this type of recommendations: the American College of Obstetrics and Gynecology and the Society of Obstetricians and Gynaecologists of Canada; and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, together with the one published by the Spanish Society of Gynecology and Obstetrics.

The "Mother Load" and Return to Sport: A Case Report of Returning to Professional Netball Following Cesarean Section

Background

Increasing numbers of elite female athletes are competing in professional sport, and many wish to become pregnant and return to competitive sport after childbirth. Athletes have a higher risk of pelvic floor dysfunction (PFD) than non-athletes (54% versus 7%) and there is also an increased prevalence in post-partum women compared to nulliparous women (35% versus 2.8-7.9%). Additionally, PFD has been shown to influence athletic performance. High quality evidence for elite athletes is lacking, and there are no exercise guidelines specifically for these women to prepare or effectively guide their safe return to sport (RTS). The purpose of this case report is to detail the management of an elite athlete who presented following cesarean section (CS) with the goal of RTS within 16 weeks.

Case Description

A 27-year-old primiparous Caucasian professional netballer presented at four weeks post- caesarean section (CS) for RTS screening and assessment of pelvic floor muscle (PFM) function. Assessment included readiness and fear of movement screening, dynamic pelvic floor muscle function, structural integrity of the CS wound, levator hiatal dimensions, bladder neck descent, and early global neuromuscular screening. Measures were collected at four weeks, eight weeks, and six months post-partum. The post-partum athlete demonstrated alterations in pelvic floor muscle function, reduced lower limb power and psychological readiness. A functionally staged dynamic and sport specific pelvic floor muscle training program was implemented and adapted to the patient for her early post-partum timeline.

Results

Rehabilitation strategies were effective in achieving the primary outcome of RTS at 16 weeks post-partum with no adverse events reported at 6 months follow-up.

Discussion

This case highlights the need for a holistic and individualised RTS management approach that includes women's and pelvic health risk factors in a professional athlete.

Supports and Barriers to Lifestyle Interventions in Women with Gestational Diabetes Mellitus in Australia: A National Online Survey

BACKGROUND

Gestational diabetes mellitus (GDM) affects approximately one in six pregnancies, causing a significant burden on maternal and infant health. Lifestyle interventions are first-line therapies to manage blood glucose levels (BGLs) and prevent future cardiometabolic complications. However, women with GDM experience considerable barriers to lifestyle interventions; thus, the aim of this study was to determine how women with GDM manage their condition and to identify the primary supports and barriers to lifestyle intervention participation.

METHODS

An online cross-sectional survey of women in Australia with a history of GDM was conducted. Questions included participant demographics, strategies used to manage BGLs, physical activity and dietary habits, and barriers and supports to lifestyle interventions.

RESULTS

A total of 665 individuals consented and responded to the advertisement, of which 564 were eligible and provided partial or complete responses to the survey questions. Most respondents were between 35 and 39 years of age (35.5%), not pregnant (75.4%), working part-time (26.7%), university-educated (58.0%), and had only one child (40.1%). Most respondents managed their BGLs through diet (88.3%), with "low-carbohydrate" diets being the most popular (72.3%), and 46.2% of respondents were undertaking insulin therapy. Only 42.2% and 19.8% of respondents reported meeting the aerobic and strengthening exercise recommendations, respectively. Women with one child or currently pregnant expecting their first child were 1.51 times more likely (95% CI, 1.02, 2.25) to meet the aerobic exercise recommendations than those with two or more children. The most common reported barriers to lifestyle intervention participation were "lack of time" (71.4%) and "childcare" commitments (57.7%). Lifestyle interventions delivered between 6 and 12 months postpartum (59.0%), involving an exercise program (82.6%), and delivered one-on-one were the most popular (64.9%).

CONCLUSION

Most women report managing their GDM with lifestyle strategies. The most common strategies reported involve approaches not currently included in the clinical practice guidelines such as reducing carbohydrate consumption. Furthermore, despite being willing to participate in lifestyle interventions, respondents report significant barriers, including lack of time and childcare commitments, whereas mentioned supports included having an online format. Lifestyle interventions for women with a history of GDM should be designed in a manner that is both tailored to the individual and considerate of existing barriers and supports to participation.

Pregnant Women's Attitudes and Beliefs towards Sleep and Exercise: A Cross-Sectional Survey

As many as 80% of women report experiencing poor sleep throughout pregnancy. Exercise is associated with many health benefits during pregnancy and is established as a non-pharmacological method to improve sleep in both pregnant and non-pregnant populations. Given the importance of sleep and exercise during pregnancy, the aim of this cross-sectional study was to (1) examine pregnant women's attitudes and beliefs towards sleep and exercise during pregnancy, and (2) investigate the barriers women face to achieving good sleep and engaging in healthy levels of exercise. Participants were comprised of 258 pregnant Australian women (31.3 ± 5.1 years) who completed a 51-question online survey. Almost all (98%) participants believed exercise during pregnancy to be safe, whilst over half (67%) believed participating in more exercise will improve their sleep. Over 70% of participants reported experiencing barriers such as physical symptoms related to pregnancy that negatively impacted their ability to exercise. Almost all (95%) participants reported experiencing barriers to sleep in their current pregnancy. Present findings suggest that overcoming intrapersonal barriers should be a priority for any intervention aiming to improve sleep or increase exercise levels in pregnant populations. Findings from the present study highlight the need for a better understanding of women's sleep experiences during pregnancy, and demonstrate how exercise may improve sleep and health outcomes.

Levels of physical activity and sitting time in women with infants, toddlers and preschoolers: a population-based cross-sectional study

OBJECTIVES

Insufficient physical activity (PA) and prolonged sitting time (ST) increase the risk of chronic disease and mortality. Caring for young children can potentially impact maternal PA and sedentary behaviours. The aims of this study were to explore the levels of PA and ST in women with young children (infants, toddlers and preschoolers) and sociodemographic and behavioural factors associated with these.

STUDY DESIGN

This was a population-based cross-sectional study.

METHODS

Survey 5 data collected in 2009 (n = 4290) of the 1973-1978 birth cohort of the Australian Longitudinal Study on Women's Health were used. Multiple linear and logistic regression models were used to examine associations.

RESULTS

In adjusted models, compared with women with preschoolers, women whose youngest child was an infant aged 0-6 months, aged >6-12 months or toddler had lower PA (-321.3 MET.min/week [95% confidence interval (CI) -416.2, -226.4], -147.9 MET.min/week [95% CI -237.6, -58.1] and -106.4 MET.min/week [95% CI -172.3, -40.5]). ST was higher in women whose youngest child was an infant aged 0-6 months (0.48 h/day; 95% CI 0.19, 0.77) but lower with infants aged >6-12 months (-0.33 h/day; 95% CI -0.60, -0.05) and toddlers (-0.40 h/day; 95% CI -0.60, -0.20) than in those with preschoolers. The findings were similar in the logistic model. Sociodemographic and behavioural factors such as occupation and marital status also influenced PA and ST.

CONCLUSIONS

Women with infants and toddlers have lower PA than women with preschoolers. Women are more likely to sit more in the first 6 months after childbirth. These findings can inform resources and intervention development to improve activity levels in women with young children through consideration of the age of the youngest child, sociodemographic and behavioural factors.

Knowledge and participation in exercise and physical activity among pregnant women in Ho, Ghana

Background

Physical activity (PA) and exercise have been identified to improve the general fitness and health. Although, the Pregnancy Physical Activity Questionnaire (PPAQ) has been validated for use in assessing PA in pregnant women. However, understanding the knowledge and participation levels of PA in pregnant women in the underdeveloped regions of Ghana is of clinical relevance to foster education and promotion of PA. In Ghana, pregnant women believe the "myth" (mostly in rural areas and underdeveloped regions) that exercising in the first trimester might lead to miscarriage. Thus, the main objective of this study was to investigate the extent of knowledge and participation levels in PA among pregnant women in Ho, Ghana using a self-developed questionnaire which consisted of some questions adapted from the PPAQ.

Methods

Seventy-seven (n = 77) pregnant women between the ages of 18-50 years were recruited from three hospitals across the Ho municipality of Ghana. A self-developed questionnaire which consisted of some questions taken from the PPAQ was administered to participants under the researchers' supervision. Spearman's correlation analysis was used to find the association between the level of participation in PA, knowledge of PA and gestational age among pregnant women.

Results

From the total participants (n = 77) recruited, 57 (74%) of the participants scored high in PA knowledge. Most of the participants 48 (62.3%) answered that PA promotes healthy pregnancy. Participants who reported barriers to PA during pregnancy were no exercise habits 51 (66.2%), having no time 17 (22.1%) and fear of miscarriage 9 (11.7%). There was a significant (p < 0.05) association between the level of participation and gestational age. No significant (p > 0.05) association between the level of participation and knowledge of PA was observed.

Conclusion

There is a high level of knowledge of PA among pregnant women in Ho, Ghana. However, most pregnant women rather engage in PA as their gestational age increases. Thus, to foster sustainable exercise participation during pregnancy, all healthcare providers saddled with the responsibility of providing maternal healthcare must strengthen the education and promotion of exercise and PA among pregnant women in Ho, Ghana.

ACTIVE PREGNANCY: Workshop on Promotion of Physical Activity in Pregnancy for Exercise Professionals

Introduction

A one-day workshop on promotion of physical activity in pregnancy for exercise professionals was delivered during 2021, to 137 participants. The main aim of this workshop was to motivate and prepare exercise professionals for promoting physical activity and implementing prenatal exercise programs, in their respective private or public fitness centers or other physical activity settings.

Methods

The contents of the workshop were focused on six topics based on the “Pregnancy and Postpartum Exercise Specialist” educational standards by EuropeActive and the “Exercise and Physical Activity during Pregnancy and Postpartum” textbook published by Springer. Participants provided feedback on the effectiveness and satisfaction with the workshop.

Results

Overall evaluations from the feedback forms showed that majority of the participants agreed that the workshop achieved its objectives with a major recommendation as to the organization of more short duration workshops, the inclusion of practical sessions, and the separation of the contents addressing the postpartum period.

Discussion

The workshop on promotion of physical activity in pregnancy for exercise professionals was successfully organized and the participants are looking forward for future ones.

Sports Obstetrics: Implications of Pregnancy in Elite Sportswomen, a Narrative Review

Increasing numbers of females are participating in elite sports, with a record number having competed at the Tokyo Olympic Games. Importantly, the ages of peak performance and fertility are very likely to coincide; as such, it is inevitable that pregnancy will occur during training and competition. Whilst there is considerable evidence to promote regular exercise in pregnancy, with benefits including a reduction in hypertensive disorders, gestational diabetes, and reduced rates of post-natal depression, few studies have been conducted which include elite athletes. Indeed, there are concerns that high-intensity exercise may lead to increased rates of miscarriage and preterm labour, amongst other pregnancy-related complications. There is minimal guidance on the obstetric management of athletes, and consequently, healthcare professionals frequently adopt a very conservative approach to managing such people. This narrative review summarises the evidence on the antenatal, intrapartum, and postpartum outcomes in elite athletes and provides recommendations for healthcare providers, demonstrating that generally, pregnant athletes can continue their training, with a few notable exceptions. It also summarises the physiological changes that occur in pregnancy and reviews the literature base regarding how these changes may impact performance, with benefits arising from pregnancy-associated cardiovascular adaptations at earlier gestations but later changes causing an increased risk of injury and fatigue.

Effects of Structured Supervised Exercise Training or Motivational Counseling on Pregnant Women's Physical Activity Level: FitMum - Randomized Controlled Trial

Background

Physical activity (PA) during pregnancy is an effective and safe way to improve maternal health in uncomplicated pregnancies. However, compliance with PA recommendations remains low among pregnant women.

Objective

The purpose of this study was to evaluate the effects of offering structured supervised exercise training (EXE) or motivational counseling on PA (MOT) during pregnancy on moderate-to-vigorous intensity physical activity (MVPA) level. Additionally, complementary measures of PA using the Pregnancy Physical Activity Questionnaire (PPAQ) and gold standard doubly labeled water (DLW) technique were investigated. The hypotheses were that both EXE and MOT would increase MVPA in pregnancy compared with standard care (CON) and that EXE would be more effective than MOT. In addition, the association between MVPA and the number of sessions attended was explored.

Methods

A randomized controlled trial included 220 healthy, inactive pregnant women with a median gestational age of 12.9 (IQR 9.4-13.9) weeks. A total of 219 women were randomized to CON (45/219), EXE (87/219), or MOT (87/219). The primary outcome was MVPA (minutes per week) from randomization to the 29th gestational week obtained by a wrist-worn commercial activity tracker (Vivosport, Garmin International). PA was measured by the activity tracker throughout pregnancy, PPAQ, and DLW. The primary outcome analysis was performed as an analysis of covariance model adjusting for baseline PA.

Results

The average MVPA (minutes per week) from randomization to the 29th gestational week was 33 (95% CI 18 to 47) in CON, 50 (95% CI 39 to 60) in EXE, and 40 (95% CI 30 to 51) in MOT. When adjusted for baseline MVPA, participants in EXE performed 20 (95% CI 4 to 36) minutes per week more MVPA than participants in CON (P=.02). MOT was not more effective than CON; EXE and MOT also did not differ. MVPA was positively associated with the number of exercise sessions attended in EXE from randomization to delivery (P=.04). Attendance was higher for online (due to COVID-19 restrictions) compared with physical exercise training (P=.03). Adverse events and serious adverse events did not differ between groups.

Conclusions

Offering EXE was more effective than CON to increase MVPA among pregnant women, whereas offering MOT was not. MVPA in the intervention groups did not reach the recommended level in pregnancy. Changing the intervention to online due to COVID-19 restrictions did not affect MVPA level but increased exercise participation.
