Effect of different physical activity interventions on perinatal depression: a systematic review and network meta-analysis

BACKGROUND

Perinatal depression can have profound impacts on both families and society. Exercise therapy is gradually becoming a widely used adjunct treatment for perinatal depression. Some studies have already focused on the relationship between physical activity and perinatal depression (PND). However, there is currently a lack of systematic and comprehensive evidence to address the crucial question of making optimal choices among different forms of physical activity. This study aims to compare and rank different physical activity intervention strategies and identify the most effective one for perinatal depression.

METHODS

Four databases, namely PubMed, Cochrane Library, Embase, and Web of Science, were searched for randomized controlled trials assessing the impact of physical activity interventions on perinatal depression. The search covered the period from the inception of the databases until May 2024. Two researchers independently conducted literature screening, data extraction, and quality assessment. Network meta-analysis was performed using Stata 15.1.

RESULTS

A total of 48 studies were included in the analysis. The results indicate that relaxation therapy has the most effective outcome in reducing perinatal depression (SUCRA = 99.4%). Following that is mind-body exercise (SUCRA = 80.6%). Traditional aerobics and aquatic sports were also effective interventions (SUCRA = 70.9% and 67.1%, respectively).

CONCLUSION

Our study suggests that integrated mental and physical (MAP) training such as relaxation therapy and mind-body exercise show better performance in reducing perinatal depression. Additionally, while exercise has proven to be effective, the challenge lies in finding ways to encourage people to maintain a consistent exercise routine.

Effectiveness of aerobic exercise in the prevention and treatment of postpartum depression: Meta-analysis and network meta-analysis

BACKGROUND

Aerobic exercise is widely recognized for improving mental health and reducing negative emotions, including anxiety. However, research on its role in preventing and treating postpartum depression (PPD) has yielded inconsistent results. Some studies show positive effects on PPD symptoms, while others find limited impact, suggesting various factors at play, such as exercise type, intensity, and individual differences. To address this gap, our study aims to comprehensively gather evidence on the preventive and therapeutic effects of aerobic exercise for PPD. We'll focus on differences in exercise program design and implementation, exploring how these factors impact intervention outcomes. By identifying effective exercise approaches, we aim to provide more comprehensive exercise prescription recommendations for this vulnerable population.

METHODS

We conducted a quantitative systematic review of the study in 5 representative databases for the effect of aerobic exercise on PPD. Meta-analysis and network meta-analysis were performed with Review-Manager.5.4 and Stata.16.0 software, respectively. This study has been registered on the official Prospero website, and the registration code is CRD42023398221.

RESULTS

Twenty-six studies with 2,867 participants were eventually included and the efficacy of aerobic exercise in preventing and treating postpartum depression is significant compared to standard care. (MD = -1.90; 95%CL: -2.58 to -1.21; I2 = 86%). Subgroup analysis suggests that the intervention objective (prevention vs. treatment) of exercise could potentially be a source of heterogeneity in this study, as the "Test for subgroup difference" revealed the presence of significant distinctions (p = 0.02<0.05). The "Test for subgroup difference" yielded non-significant results for both the supervised vs. unsupervised subgroup comparison (p = 0.55 > 0.05) and the individual vs. team subgroup comparison (p = 0.78 > 0.05). Nonetheless, when assessing their effect sizes [Subtotal (95%CL)], the supervised exercise group [-1.66 (-2.48, -0.85)] exhibited a slightly better performance than the unsupervised exercise group [-1.37 (-1.86, -0.88)], while the team exercise group [-1.43 (-1.94, -0.93)] slightly outperformed the individual exercise group [-1.28 (-2.23, -0.33)]. Network meta-analysis indicated that moderate intensity (35~45 min) group demonstrated a more pronounced intervention effect compared to low intensity (50~60 min) group [-2.63 (-4.05, -1.21)] and high intensity (20~30 min) group [-2.96 (-4.51, -1.41)], while the 3~4 times/week group had a more significant intervention effect compared to 1~2 times/week groups [-2.91 (-3.99, -1.83)] and 5~6 times/week groups [-3.28 (-4.75, -1.81)]. No significant differences were observed in pairwise comparisons of intervention effects among the five common types of aerobic exercises. (95%CL including 0). The Surface Under the Cumulative Ranking curve (SUCRA) results align with the findings mentioned above and will not be reiterated here.

CONCLUSION

The efficacy of aerobic exercise in preventing and treating postpartum depression is significant compared to standard care, with a greater emphasis on prevention. The optimal prescribed exercise volume for intervention comprises a frequency of 3~4 exercise sessions per week, moderate intensity (35~45 minutes). Currently, several uncharted internal factors influence the optimal intervention effect of aerobic exercise, such as the potential enhancement brought by team-based and supervised exercise. Given the absence of significant differences in certain results and the limitations of the study, it is essential to exercise caution when interpreting the outcomes. Further research is needed in the future to provide a more comprehensive understanding.

The impact of physical activity intervention on perinatal depression: A systematic review and meta-analysis

BACKGROUND

No meta-analysis has analyzed the effect of physical activity level, period of physical activity intervention, and duration of intervention, on perinatal depression. This study was to evaluate the impact of physical activity intensity, dose, period, and duration on perinatal depression.

METHODS

The literature was searched via the PubMed, Embase, Cochrane Library, and Web of Science databases. Weighted mean difference (WMD) or the risk ratio (RR) was used as the effect indicator, and the effect size was represented by the 95 % confidence interval (CI). Subgroup analysis based on the perinatal stage, physical activity intensity, physical activity equivalent, and intervention duration was performed.

RESULTS

Totally, 35 studies including 5084 women were included. Physical activity could reduce the incidence and severity of depression in perinatal women. Among depressed women with prenatal depression, low-intensity physical activity, with metabolic equivalents (METs)-min/week being <450, was associated with lower levels of depression. In the general population, the risk of postpartum depression was lower in the physical activity group when the duration of intervention was ≥12 weeks, being II, III stage, and ≥450 METs-min/week. Both low and moderate-intensity physical activity were beneficial to an improved depression severity among depressed women with postpartum depression, and moderate exercise intervention could decrease the risk of postpartum depression in general pregnant women.

LIMITATIONS

Different types of physical activities may affect the effectiveness of interventions.

CONCLUSION

Our study indicated physical activity specifically targeted at pregnant women could reduce depression risk and severity.

Physical exercise interventions for perinatal depression symptoms in women: A systematic review and meta-analysis

Background

The previous meta-analysis indicated that physical exercise could play a crucially therapeutic role in reducing perinatal depression symptoms in women. However, the efficacy varies across different exercise types, forms, intensities, and duration.

Aim

The purpose of this study was to review and evaluate the effects of different types, forms, intensities, and duration of exercise for improving perinatal depressive symptoms.

Design

A systematic review and meta-analysis.

Methods

Randomized controlled trials until December 2021 were searched from seven databases, including PubMed, EMBASE, Medline, CINAHL, Web of Science, Cochrane Library, and PsycINFO. The risk of bias in eligible trials was evaluated using the Cochrane Risk of Bias tool. When high heterogeneity was tested, we used random-effects models. A funnel plot was used to assess the publication bias. This review was performed under the PRISMA guidelines, Consensus on Exercise Reporting (CERT) checklist and Cochrane Handbook. The certainty of the body of evidence was assessed using the GRADE method.

Results

Of 1,573 records, 20 trials were identified in this study. The results of this review revealed that women with perinatal depression symptoms gained benefits from physical exercise [OR = 0.62, 95% CI (0.45, 0.86), P = 0.004; MD = -0.57, 95% CI (-0.83, -0.30), P < 0.0001]. Type of walking [SMD = -1.06, 95% CI (-1.92, -0.19), P < 0.00001], form of "Individual + group-based"exercise [SMD = -0.91, 95% CI (-0.80, -0.03), P = 0.04], intensity of ≥150 min per week [SMD = -0.84, 95% CI (-1.53, -0.15), P = 0.02], and ≥12 weeks duration [SMD = -0.53, 95% CI (-0.75, -0.31), P < 0.00001] seemed to generate more prominent improvement on perinatal depression symptoms.

Conclusion

Physical exercise showed a significant effect on reducing perinatal depressive symptoms. This meta-analysis provides an important update on exercise's efficacy in treating perinatal depression. Further higher quality and large-scale trials are needed to substantiate our findings.

Quality of Life in the Postpartum Recovery of Women Who Practice Hypopressive Exercise: Randomized Clinical Trial

Background: Practicing physical exercise is a way of maintaining a healthy lifestyle and it has been demonstrated to provide benefits and improve quality of life after labour. Aim: The objective of this study is to determine if performing a moderate hypopressive exercise program after childbirth improves the HRQoL of women. Materials and Methods: A 12-week randomized clinical trial was carried out. The women in the exercise group followed a training program based on the hypopressive method, which comprises postural and respiratory exercises of moderate intensity. We used the SF-36v2 questionnaire to assess the Health-Related Quality of Life in women. Results: We found statistically significant differences (p < 0.05) in general health components, vitality, emotional role, and mental health in the sample group of exercise group of women, who obtained a higher score. We found statistically significant differences in all aspects between the groups. The interaction between time and group affect in general health components, vitality, emotional role and the score of mental components. In all of them, the score was higher at the end of the programme and in the exercise group. Conclusions: The training program with hypopressive physical exercise improves the quality of life after childbirth. According to the guidelines recommended by the ACOG, the hypopressive method is valid for the improvement of HRQoL in women who perform this method at 16 weeks of delivery. Further studies are recommended to start such exercises one week after delivery in postpartum women.

Factors influencing physical activity in postpartum women during the COVID-19 pandemic: a cross-sectional survey in Japan

Background

The aim of this study was to investigate factors influencing postpartum physical activity (PA), taking into consideration psychosocial perceptions during the coronavirus disease 2019 (COVID-19) pandemic by comparing health-related quality of life (HRQoL) scores.

Methods

A web-based cross-sectional survey of 787 postpartum women was conducted between March and October 2021. After applying the exclusion criteria, 590 women were analyzed. The International Physical Activity Questionnaire Short Form, was used to assess the level and amount of PA. The Short Form-12 Health Survey version 2 (SF-12v2) was used to measure HRQoL. Logistic regression analyses were used to determine whether sociodemographic factors and psychosocial perceptions during the COVID-19 pandemic were associated with the level of PA. Based on the current national guidelines for exercise in Japan, respondents were classified by weekly PA level as an Inactive group and an Active group to assess the influence of PA on HRQoL.

Results

Mean total PA was 19.3 total metabolic equivalents hour/week, and the prevalence of an inactive lifestyle was 45.9% among respondents. Each year of age was associated with an odds ratio (OR) of 0.92 (95% CI 0.87–0.97) for becoming physical inactivity during postpartum. Factors positively associated with more active levels were greater number of days for delivery (OR = 1.00; 95% CI 1.00–1.01), multiparity (OR = 1.50; 95% CI 1.00–2.23), having someone to talk about childcare and the individual’s partner (OR = 2.04; 95% CI 0.96–4.36) and not having anxiety symptoms (OR = 0.58; 95% CI 0.35–0.97). The Active group had significantly higher HRQoL scores than the Inactive group in the following scales: physical component summary (p < 0.001), mental component summary (p = 0.041).

Conclusions

The influential factors for postpartum PA level were younger age, longer duration after childbirth, multiparity and not having anxiety symptoms, which correlated positively with PA. The presence of someone with whom can talk to about childcare and partner issues was associated with the maintenance of higher PA among postpartum women, suggesting that factor as a positive influence on PA under unsettled conditions.

Does perinatal period pelvic floor muscle exercises affect sexuality and pelvic muscle strength? A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE:

The aim of this study was to systematically review the effect of pelvic floor exercises on female sexual function and pelvic floor strength in the prenatal and postnatal periods and to conduct a meta-analysis of available evidence.

METHODS:

Published archives, including PubMed, Cochrane Library, Web of Science, and ULAKBİM databases, were scanned using keywords based on MeSH. Only randomized controlled trials were included. The data were analyzed using the Review Manager computer program (version 5.3).

RESULTS:

Pooled standardized differences in means of sexual function in both pelvic floor exercise and control group were 6.33 (95%CI 5.27–7.40, p<0.00001) during pregnancy. The pooled standardized differences in means in sexual function after postpartum intervention was 1.19 (95%CI 0.08––2.30, p=0.04).

CONCLUSION:

Evidence has shown a little effect on the pelvic floor muscle training on sexual function in pregnancy and postpartum period in primipara women, and it is a safe strategy that can improve postpartum sexual function.

The effectiveness of exercise-based interventions for preventing or treating postpartum depression: a systematic review and meta-analysis

Postpartum depression can have detrimental effects on both a mother's physical and mental health and on her child's growth and emotional development. The aim of this study is to assess the effectiveness of exercise/physical activity-based interventions in preventing and treating postpartum depressive symptoms in primiparous and multiparous women to the end of the postnatal period at 52 weeks postpartum. Electronic databases were searched for published and unpublished randomised controlled trials of exercise/physical activity-based interventions in preventing and treating depressive symptoms and increasing health-related quality of life in women from 4 to 52 weeks postpartum. The results of the studies were meta-analysed and effect sizes with confidence intervals were calculated. The Grading of Recommendations Assessment and Development and Evaluation (GRADE) system was used to determine the confidence in the effect estimates. Eighteen trials conducted across a range of countries met the inclusion criteria. Most of the exercise interventions were aerobic and coaching compared to usual care, non-intervention and active controls. Small effect sizes of exercise-based interventions in reducing depressive symptoms were observed collectively and the quality of evidence was low across the individual studies. Although exercise-based interventions could create an alternative therapeutic approach for preventing major depression in postpartum women who experience subthreshold elevated depressive symptoms, the clinical effectiveness and the cost-effectiveness of exercise-based and physical activity interventions need to be better established. There is a need for further more rigorous testing of such interventions in high-quality randomised controlled trials against active control conditions before large-scale roll-out of these interventions in clinical practice is proposed.

Does aerobic exercise reduce postpartum depressive symptoms? a systematic review and meta-analysis

BACKGROUND

There is currently no specific guidance on the role of exercise in managing postpartum depression in the UK and US, and international guidance is inconsistent.

AIM

To assess the effectiveness of aerobic exercise on postpartum depressive symptoms.

DESIGN AND SETTING

Systematic review and meta-analysis. There was no restriction to study site or setting.

METHOD

The databases MEDLINE, EMBASE, Cochrane Library, PsycINFO, SportDiscus, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform were searched. Titles and abstracts, then full-text articles, were screened against inclusion criteria: RCTs measuring depressive symptoms in mothers ≤1 year postpartum; and interventions designed to increase aerobic exercise compared with usual care or other comparators. Included studies were assessed using the Cochrane Collaboration's risk of bias tool. Meta-analysis was conducted. Pre-planned subgroup analyses explored heterogeneity.

RESULTS

Thirteen RCTs were included, with 1734 eligible participants. Exercise significantly reduced depressive symptoms when all trials were combined (standardised mean difference -0.44; 95% confidence interval = -0.75 to -0.12). Exploration of heterogeneity did not find significant differences in effect size between women with possible depression and in general postpartum populations; exercise only and exercise with co-interventions; and group exercise and exercise counselling.

CONCLUSION

This systematic review provides support for the effectiveness of exercise in reducing postpartum depressive symptoms. Group exercise, participant-chosen exercise, and exercise with co-interventions all may be effective interventions. These results should be interpreted with caution because of substantial heterogeneity and risk of bias.

Effects of Exercise on Mild-to-Moderate Depressive Symptoms in the Postpartum Period: A Meta-analysis

OBJECTIVE

To examine the influence of exercise on depressive symptoms and the prevalence of depression in the postpartum period.

DATA SOURCES

A structured search of MEDLINE, EMBASE, CINAHL, Sport Discus, Ovid's All EBM Reviews, and ClinicalTrials.gov databases was performed with dates from the beginning of the databases until June 16, 2016. The search combined keywords and MeSH-like terms including, but not limited to, "exercise," "postpartum," "depression," and "randomized controlled trial."

METHODS OF STUDY SELECTION

Randomized controlled trials comparing postpartum exercise (structured, planned, repetitive physical activity) with the standard care for which outcomes assessing depressive symptoms or depressive episodes (as defined by trial authors) were assessed. Trials were identified as prevention trials (women from the general postpartum population) or treatment trials (women were classified as having depression by the trial authors). Effect sizes with 95% confidence intervals (CIs) were calculated using Hedges' g method and standardized mean differences in postintervention depression outcomes were pooled using a random-effects model.

TABULATION, INTEGRATION, AND RESULTS

Across all 16 trials (1,327 women), the pooled standardized mean difference was -0.34 (95% CI -0.50 to -0.19, I=37%), suggesting a small effect of exercise among all postpartum women on depressive symptoms. Among the 10 treatment trials, a moderate effect size of exercise on depressive symptoms was found (standardized mean difference-0.48, 95% CI -0.73 to -0.22, I=42%). In six prevention trials, a small effect (standardized mean difference-0.22, 95% CI -0.36 to -0.08, I=2%) was found. In women with depression preintervention, exercise increased the odds of resolving depression postintervention by 54% (odds ratio 0.46, Mantel-Haenszel method, 95% CI 0.25-0.84, I=0%). The trials included in this meta-analysis were small and some had methodologic limitations.

CONCLUSION

Light-to-moderate intensity aerobic exercise improves mild-to-moderate depressive symptoms and increases the likelihood that mild-to-moderate depression will resolve.
