Abstract: There is an increasing interest in peer interventions in the management of chronic conditions, but evidence on peer interventions for body weight is lacking. The aim of this study was to examine the efficacy of peer interventions on body weight, energy intake, and physical activity in adults. Interventions delivered by peer (lay member that participants identify with) were included. We searched 14 databases. Outcomes were combined in the meta‐analysis using the inverse variance random‐effects model. From 2435 articles, 65 articles were included in the systematic review and meta‐analysis ( n = 15,673). Peer interventions resulted in significant reduction in weight (mean difference [MD] −1.05 kg 95% confidence interval [CI] −1.68, −0.43 95% prediction interval [PI] −3.25, 1.14 28 studies 7142 participants), BMI (MD −0.24 kg/m 2 95% CI −0.44, −0.04 95% PI −0.92, 0.45 25 studies 6672 participants), waist circumference (MD −0.75 cm 95% CI −1.29, −0.21 95% PI −1.36, −0.14 12 studies 4280 participants), and significant increase in physical activity (SMD 0.20 95% CI 0.09, 0.32 95% PI −0.46, 0.86 41 studies 10,778 participants) with no significant effect on energy intake. This study suggests peer interventions are effective in reducing waist circumference, but further research is needed to confirm its effect on other obesity‐related outcomes.

Abstract: Postpartum weight retention contributes to maternal obesity and varies by ethnicity. Despite the well-established benefits of lifestyle intervention on weight management, little is known about how to engage postpartum women effectively, especially among ethnic minority groups. This multi-methods study aimed to explore ethnic differences in women’s preferences for lifestyle intervention after childbirth. Women within five years of childbirth and living with their youngest child in Australia were recruited in an online survey (n = 504) and semi-structured interviews (n = 17). The survey and interview questions were structured based on the Template for Intervention Description and Replication (TIDieR) framework. Ethnic groups were categorized as Oceanian, Asian and Other according to the Australian Bureau of Statistics. Chi-square tests were used to compare the preferred intervention characteristics between groups. Qualitative data were thematically analysed. The survey showed that most women across all ethnic groups were interested in receiving lifestyle support in the early postpartum period (from 7 weeks to 3 months postpartum). All ethnic groups preferred a regular lifestyle intervention delivered by health professionals that promotes accountability and provides practical strategies. However, Asian women had a higher desire for infant care and a lower desire for mental health in the intervention content compared with Oceanian women. Moreover, Asian women were more likely to favour interventions that are initiated in a later postpartum period, over a shorter duration, and with less intervention frequency, compared with Oceanian women. The interviews further indicated the need for intervention adaptations in the Asian group to address the cultural relevance of food and postpartum practices. These ethnic-specific preferences should be considered in the development of culturally appropriate intervention strategies to optimize engagement in healthy lifestyles among the targeted ethnic groups.

Abstract: Lifestyle intervention is effective in preventing type 2 diabetes mellitus (T2DM), but the efficacy of intervention components across different ethnic groups is less clear. This systematic review examined the effects of intervention characteristics of lifestyle interventions on diabetes incidence and weight loss by ethnicity using the Template for Intervention Description and Replication (TIDieR) framework. MEDLINE, EMBASE and other databases were searched for randomized and non-randomized controlled trials on lifestyle interventions (diet and/or physical activity) in adults at risk of T2DM. Ethnicity was categorized into European, South Asian, East and Southeast Asian, Middle Eastern, Latin American and African groups. Forty-five studies (18,789 participants) were included in the systematic review and 41 studies in meta-analysis. Meta-analysis showed a high number of intervention sessions was significantly associated with a greater reduction in diabetes incidence (P = 0.043) and weight (P = 0.015), while other intervention characteristics including intervention provider and delivery format did not alter the outcomes (all P 0.05). Additionally, narrative synthesis showed long-term interventions (≥12 months) were associated with significant diabetes risk reduction for all ethnic groups, while short-term interventions ( months) were more effective in weight loss in most ethnic groups. There may be ethnic preferences for the optimal number of intervention sessions.

Abstract: The risk of type 2 diabetes mellitus (T2DM) varies by ethnicity, but ethnic differences in response to diabetes prevention interventions remain unclear. This systematic review and meta‐analysis assessed ethnic differences in the effects of lifestyle interventions on T2DM incidence, glycemic outcomes (fasting glucose, 2‐h glucose, HbA 1c ), anthropometric measures (weight, BMI, waist circumference), and lifestyle behaviors (physical activity, energy intake, energy from fat, fiber intake). MEDLINE, EMBASE, and other databases were searched (to June 15, 2020) for randomized and non‐randomized controlled trials on lifestyle interventions (diet and/or physical activity) in adults at risk of T2DM. Ethnicity was categorized into European, South Asian, East and Southeast Asian, Middle Eastern, Latin American, and African groups. Forty‐four studies were included in meta‐analyses. Overall, lifestyle interventions resulted in significant improvement in T2DM incidence, glycemic outcomes, anthropometric measures, physical activity, and energy intake (all P 0.01). Significant subgroup differences by ethnicity were found for 2‐h glucose, weight, BMI, and waist circumference (all P 0.05) but not for T2DM incidence, fasting glucose, HbA 1c , and physical activity (all P 0.05). Few studies in non‐European groups reported dietary intake. Lifestyle interventions in different ethnic groups may have similar effects in reducing incidence of T2DM although this needs to be confirmed in further studies.

Abstract: Gestational diabetes mellitus (GDM) places a woman at high risk of developing subsequent type 2 diabetes mellitus (T2DM), particularly in the first 5 years postpartum. Engaging women in health behavior change during this period is challenging and current diabetes prevention programs were developed for middle-aged adults, all of which have limited the evidence on successful implementation for this high-risk population. In this review, we will first summarize the effects of existing diabetes prevention programs in women with a history of GDM. Second, we suggest that the programs need to be modified according to the facilitators and barriers faced by this population. Third, we propose that improving program penetration, fidelity, and participation is critical for population-level success. Finally, we outline the research priorities to improve the implementation of diabetes prevention programs for postpartum women with a history of GDM.

Abstract: Postpartum lifestyle interventions are known to be efficacious in reducing postpartum weight retention, but uptake and engagement are poor. This multi-method study explored the preferences of postpartum women for the delivery of lifestyle interventions based on the Template for Intervention Description and Replication (TIDieR) checklist. Semi-structured interviews were conducted with 21 women within 2 years of childbirth, recruited through convenience and snowball s ling throughout Australia (15 May 2020 to 20 July 2020). Transcripts were analysed thematically using an open coding approach. A cross-sectional online survey was conducted in November 2021 among postpartum women within 5 years of childbirth in Australia. Data were summarised using descriptive statistics. The survey was completed by 520 women. Both the survey and interviews revealed that women were interested in receiving lifestyle support postpartum and wanted a program delivered by health professionals. They preferred a flexible low-intensity program embedded within existing maternal and child health services that is delivered through both online and face-to-face sessions. Having a pragmatic approach that taught practical strategies and enlists the support of partners, family and peers was important to mothers. Consumer-informed postpartum lifestyle interventions promote optimal engagement and improve program reach and therefore, impact.

Abstract: Postpartum weight retention (PPWR) contributes to maternal obesity development and is more pronounced in culturally and linguistically erse (CALD) women. Our antenatal healthy lifestyle intervention (HeLP-her) demonstrated efficacy in reducing PPWR in non-Australian-born CALD women compared with Australian-born women. In this secondary analysis, we aimed to examine differences in the intervention effect on behavioral and psychosocial outcomes between Australian-born and non-Australian-born women and explore factors associated with the differential intervention effect on PPWR. Pregnant women at risk of gestational diabetes (Australian-born n = 86, non-Australian-born n = 142) were randomized to intervention (four lifestyle sessions) or control (standard antenatal care). PPWR was defined as the difference in measured weight between 6 weeks postpartum and baseline (12–15 weeks gestation). Behavioral (self-weighing, physical activity (pedometer), diet (fat-related dietary habits questionnaire), self-perceived behavior changes), and psychosocial (weight control confidence, exercise self-efficacy, eating self-efficacy) outcomes were examined by country of birth. Multivariable linear regression analysis was conducted to assess factors associated with PPWR. The intervention significantly increased self-weighing, eating self-efficacy, and self-perceived changes to diet and physical activity at 6 weeks postpartum in non-Australian-born women, compared with no significant changes observed among Australian-born women. Intervention allocation and decreased intake of snack foods were predictors of lower PPWR in non-Australian-born women. Results indicate that the HeLP-her intervention improved dietary behaviors, contributing to the reduction of PPWR in CALD women. Future translations could prioritize targeting diet while developing more effective strategies to increase exercise engagement during pregnancy in this population.
