The Effect of the More Active MuMs in Stirling Trial on Body Composition and Psychological Well-Being among Postnatal Women

Group-based physical activity interventions for postpartum women with children aged 0-5 years old: a systematic review of randomized controlled trials

BACKGROUND

It is estimated that less than one third of women (28%) worldwide, are not sufficiently active, and there is evidence indicating physical activity (PA) participation is lower during pregnancy and the postpartum period. Despite the importance of educating and encouraging postpartum women to engage in PA, existing systematic reviews have only focused on examining the impact of individually tailored PA interventions and on specific postpartum populations such as women who are inactive (i.e., do not meet PA recommendations) or women at risk of gestational diabetes mellitus or postnatal depression. This review aims to fill this gap by examining the impact of group-based PA interventions on postpartum women's PA levels or other health behavior outcomes.

METHODS

A systematic literature search was conducted using four electronic databases (MEDLINE, CINAHL, EMBASE and PsychInfo) of published studies between 1st January 2000 and 31st October 2020. Studies were included if they targeted postpartum women with no current health conditions, had children aged 0-5 years, and engaged postpartum women in a group-based PA program that reported PA or other health behavior outcomes. Out of a total of 1091 articles that were initially identified, six were included.

RESULTS

Group-based PA interventions were moderately successful in changing or increasing postpartum women's self-reported PA levels and psychological wellbeing in the first 2 years of their offspring's life. Overall, group-based PA interventions were not successful in changing or increasing postpartum women's objectively measured PA levels, but only one study objectively measured postpartum women's PA levels. Narrative synthesis highlights the heterogeneity of the outcomes and methodologies used, and the low to medium risk of bias in the included studies.

CONCLUSION

To strengthen the evidence-base for group-based PA programs with postpartum women there is an on-going need for more rigorous randomised controlled trials of appropriate length (at least 3 months in duration) with an adequate dose of group-based PA sessions per week (to meet PA guidelines), and that utilise objective measures of PA. In addition, future PA interventions for this population should include, at the very least, fidelity and process data to capture the characteristics or design features that appeal most to postpartum women.

Effectiveness of non-pharmacological interventions for reducing postpartum fatigue: a systematic review protocol

INTRODUCTION

Postpartum fatigue is a common symptom among new mothers after their pregnancy. It has a considerable negative impact on women's functional and mental status as well as the development of babies. Identifying effective interventions to prevent or reduce postpartum fatigue is meaningful to improve the quality of life and avoid adverse outcomes of this vulnerable population. This systematic review aims to synthesise non-pharmacological evidence and evaluate the effectiveness of interventions for reducing postpartum fatigue among puerperas.

METHODS AND ANALYSIS

This review will be conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. We will systematically search the Cochrane Library, PubMed, Embase, Web of Science, PsycINFO, CINAHL and ProQuest databases to identify clinical trials implementing non-pharmacological interventions conducted during 0-78 weeks postpartum for fatigue reduction. An additional search of OpenGrey will be conducted to identify grey literature. The search will be performed on 30 March 2021 without restrictions on time and language. Two independent reviewers will be responsible for study selection, data extraction and study quality assessment. The Cochrane risk-of-bias tool will be adopted to evaluate the risk biases of the included randomised controlled trials, and the Risk of Bias in Non-randomised Studies of Interventions will be applied to evaluate non-randomised controlled trials. Any disagreements will be referred to a third reviewer to reach a consensus. Findings will be qualitatively synthesised, and a meta-analysis will be conducted for the statistical combination if outcome data are sufficient and available.

ETHICS AND DISSEMINATION

This systematic review will not involve the collection of primary data and will be based on published data. Therefore, ethics approval is not required. The final findings will be disseminated through peer-reviewed journals and academic conferences.

Effectiveness of nonpharmacological interventions for reducing postpartum fatigue: a meta-analysis

BACKGROUND

Postpartum fatigue is the most common issue among postnatal women and it could not only seriously affect the health of mothers but also bring about adverse impacts on their offspring. This meta-analysis aims to synthesize nonpharmacological evidence and evaluate the effectiveness of interventions for reducing postpartum fatigue among puerperae.

METHODS

The Cochrane Library, PubMed, Embase, Web of Science, PsycINFO, CINAHL and ProQuest databases were searched for papers published from inception until June 2021. Grey literature was searched using OpenGrey. Randomized controlled trials (RCTs) or controlled clinical trials (CCTs) evaluating nonpharmacological interventions conducted during 0 ~ 78 weeks postpartum for fatigue reduction were eligible for inclusion. The methodological quality of the included studies was independently assessed by two reviewers using the Cochrane risk-of-bias tool and the risk of bias in nonrandomized studies of interventions. Cohen's kappa coefficient was used to measure inter-rater agreement. The meta-analysis was conducted using Review Manager 5.3.

RESULTS

Seventeen published clinical trials matched the eligibility criteria and ten studies involving 1194 participants were included in this meta-analysis. The intervention start time varied from immediately postpartum care to 1 year after delivery, and duration ranged from 1 day to 3 months. The results revealed that exercise (SMD = - 1.74, 95% CI = -2.61 to - 0.88) and drinking tea (MD = - 3.12, 95% CI = -5.44 to - 0.80) resulted in significant improvements in women's postpartum fatigue at postintervention. Drinking tea may have beneficial effects on depression (MD = - 2.89, 95% CI = -4.30 to - 1.49). Positive effects of psychoeducational interventions on postpartum fatigue or depression were not observed. Physical therapies including mother-infant skin-to-skin contact, taking warm showers and breathing lavender oil aroma were used for reducing postpartum fatigue. No significant risk of publication bias was found. Small number of included studies and sample sizes, not time-matched conditions of control groups, high heterogeneity and the risk of bias within the included studies were the main limitations of our review.

CONCLUSIONS

This review provides evidence that exercise and drinking tea may be effective nonpharmacological interventions for relieving postpartum fatigue. More effective and targeted exercise programs need to be further studied. Rigorous RCTs of drinking tea are needed. Caution is required when interpreting the findings due to the limitations of our study. Further studies are still needed to validate our findings and increase confidence in the results.

The Role of Health Literacy in Postpartum Weight, Diet, and Physical Activity

Background: Postpartum weight retention is a significant contributor to obesity in women, adverse perinatal events in subsequent pregnancies, and chronic disease risk. Health literacy is known to impact health behaviors. The study aimed to identify the health literacy domains utilized in postpartum weight management interventions and to determine their impact on weight, diet and physical activity in postpartum women. Methods: We searched MEDLINE, CINAHL, EMBASE, PSYCINFO, and EBM databases. We included random control trials of lifestyle intervention in postpartum women (within two years post-delivery) published up to 3 May 2019. Subgroup analyses were performed to determine the effect of health literacy domains on outcomes. Results: Out of 5000 studies, 33 studies (n = 3905) were included in the systematic review and meta-analysis. The health literacy domain self-care (skills and knowledge) was associated with a significant reduction in body weight (mean difference (MD) −2.46 kg; 95% confidence interval (CI) from −3.65 to −1.27) and increase in physical activity (standardized mean difference (SMD) 0.61; 95% CI 0.20 to 1.02). No other health literacy domain was associated with significant outcomes in weight, energy intake, or physical activity. Conclusions: Health literacy skills such as knowledge of self-care are effective in improving weight and in increasing physical activity in postpartum women. The efficacy of other health domains was not supported.

The Concurrent Acceptability of a Postnatal Walking Group: A Qualitative Study Using the Theoretical Framework of Acceptability

Walking groups are often enjoyed by postnatal women, but little is known about what makes them an acceptable activity to this group. This study aimed to investigate the acceptability of a postnatal walking group using the Theoretical Framework of Acceptability (TFA). Seventeen postnatal women took part in a walk-along interview during a walking group session. Semi-structured interviews were based on the TFA and findings were analysed deductively onto the seven TFA components. Overall, the walking group was found to be acceptable. Benefits included meeting other mothers and walking in an accessible and convenient location. Women understood the group aim of supporting new mothers and thought it achieved this aim. Most women reported that attending the group was little effort, although for some the timing did not fit well with their baby's schedule. Participants stated that meeting other mothers and being physically active aligned with their value system. In conclusion, the acceptability of the walking group was found to be multifaceted, of which enjoyment was one part. These findings can be used when advertising other walking groups or physical activities for the postnatal population.

An evaluation of the impact of lifestyle interventions on body weight in postpartum women: A systematic review and meta-analysis

The established efficacy in postpartum lifestyle interventions has not been translated into better outcomes. This systematic review and meta-analysis assess the penetration (the proportion of women invited within the target population), implementation (fidelity), participation (the proportion of those invited who enrolled), and effect (weight loss compared to controls) (PIPE) of randomized controlled trials of lifestyle interventions in postpartum women (within two years after birth). MEDLINE, EMBASE, Pubmed, and other databases and clinical trial registries were searched up to the 3rd of May 2019. Data was extracted from published reports and missing data was obtained from study authors. The quality of the studies was appraised using the Cochrane Risk of Bias tool (2·0). Main outcomes were the PIPE impact metrics and changes in body weight. Thirty-six trials (49 publications) were included (n=5,315 women). One study provided sufficient information to calculate the population penetration rate (2·5%). All studies provided implementation (fidelity) information, but over half had low program fidelity. The participation rate was calculated for nine studies (0·94% to 86%). There was significant change in body weight (mean difference (MD) (95% confidence interval, CI) of -2·33 (-3·10 to -1·56). This highlights the inadequacy of conventional RCTs to inform implementation. Future research should broaden methods to pragmatic trials.

Inequities and inequalities in outdoor walking groups: a scoping review

Background

Outdoor walking groups are widely-used programmes aimed at improving physical activity and health outcomes. Despite being promoted as accessible and inclusive, emerging work highlights participation biases based on gender, age and socioeconomic status, for example. To explicate the impact of outdoor walking groups on physical activity inequities, we conducted a scoping review of published outdoor walking group literatures. Specifically, we critically examined: (a) equity integration strategies; (b) intervention reach; (c) effectiveness; and (d) potential social determinants of engagement relating to the World Health Organization’s conceptual framework.

Methods

Arksey and O’Malley’s scoping review protocol was used to develop a comprehensive search strategy and identify relevant academic and grey literatures, which were screened using pre-defined inclusion and exclusion criteria. Data were organised by Cochrane PROGRESS-Plus equity characteristics and a narrative summary was presented for each thematic area.

Findings

Sixty-two publications were included. Key findings were: (a) some evidence of targeted intervention trials. Large-scale national programmes were tailored to regional activity and health needs, which may contribute toward addressing inequities. However, participant demographics seldom informed reported analyses; (b) participation was more likely among white, more socioeconomically advantaged, middle-to-older aged, female and able-bodied adults; (c) positive physical and psychological outcomes were unlikely to extend along social gradients; and (d) interventions primarily addressed intermediary determinants (e.g. psychosocial barriers; material resource). Social capital (e.g. friend-making) was identified as potentially important for addressing physical activity inequalities.

Conclusions

The published literature on outdoor walking groups leaves unanswered questions regarding participation inequalities, with implications for future physical activity promotion. Currently, participation in outdoor walking groups is typically more prevalent among advantaged subpopulations. We make recommendations for research and practice to address these issues, as well as aid the translation of existing knowledge into practice. We advocate increased focus on the social determinants of engagement. A more consistent approach to collecting and analysing participant socio-demographic data is required. Our findings also support recommendations that appropriate tailoring of universal programmes to community needs and embedding strategies to increase social cohesion are important in developing equitable programmes.

A systematic review and meta-analysis of intervention characteristics in postpartum weight management using the TIDieR framework: A summary of evidence to inform implementation

Postpartum weight retention is a significant contributor to obesity in reproductive-aged women, but the key implementation characteristics of postpartum weight management interventions have not been systematically identified to inform policy and practice. This study aimed to evaluate the intervention characteristics associated with weight loss in postpartum women using the Template for Intervention Description and Replication (TIDieR) framework. We searched MEDLINE, CINAHL, EMBASE, PSYCINFO, and EBM databases to identify lifestyle intervention RCTs in postpartum women (within 2 years after birth) published up to January 2018. From 4512 studies, 33 studies were included in the systematic review and meta-analysis (n = 4960 women). Health professional-delivered interventions had significantly greater weight loss than those delivered by nonhealth professionals (mean difference, 95% confidence interval: (-3.22 kg [-4.83, -1.61] vs -0.99 kg [-1.53, -0.45], P = 0.01 for subgroup differences)). Diet and physical activity combined had significantly greater weight loss compared with physical activity-only interventions (-3.15 kg [-4.34, -1.96] vs -0.78 kg [-1.73, 0.16], P = 0.009 for subgroup differences). The extent of weight loss was not influenced by intervention intensity (duration, number of sessions) and setting (individual or group).

Walking on sunshine: scoping review of the evidence for walking and mental health

BACKGROUND/OBJECTIVES

Walking has well-established positive relationships with, and effects on, physical health. In contrast, while poor mental health contributes substantially to global health burden, an overview of the benefits from walking has not previously been published. We aimed to scope the literature and present what is known, and highlight what is not known, about walking and mental health.

METHODS

Design: Scoping review.

DATA SOURCES

Ovid (Medline), ProQuest, Web of Science.Screening and reporting: 13 014 records were identified and screened by a team of researchers. Included full texts were analysed and reported according to mental health outcome.

RESULTS

For the 8 mental health outcomes (identified a priori), there were a total of 5 systematic reviews and 50 individual papers included. Depression had the most evidence and existing systematic reviews were reported. Evidence for anxiety, psychological stress, psychological well-being, subjective well-being and social isolation and loneliness varied in volume and effectiveness, but no harmful effects were identified. There were no studies for walking and resilience. The setting and context of walking seems to be important variables.

CONCLUSION

The evidence base that suggests walking benefits mental health is growing, but remains fragmented and incomplete for some important outcomes. Policy and national guidelines should promote the known mental health benefits of increased walking and future research should directly address the gaps we have identified.
