Systematic review and meta-analysis of pregnancy outcomes in women with polycystic ovary syndrome.

Screening for polycystic ovary syndrome (PCOS) in antenatal care is inadequate, largely owing to the lack of clarity around whether PCOS is an independent risk factor for pregnancy complications. This systematic review and meta-analysis include 104 studies and 106,690 pregnancies in women with and without PCOS from inception until 13th July 2022. We report that women with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of miscarriage, gestational diabetes mellitus, gestational hypertension, pre-eclampsia and cesarean section are higher in women with PCOS. The increased odds of adverse outcomes in PCOS remain significant when age and BMI are matched and when analyses are restricted to high-quality studies. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured in all women who are planning to, or have recently become pregnant to facilitate prevention of adverse outcomes and improve pregnancy outcomes.

Systematic review and meta-analysis of birth outcomes in women with polycystic ovary syndrome.

It is unclear whether polycystic ovary syndrome (PCOS) is an independent risk factor for adverse birth outcomes in the offspring of affected women. Here, we investigate the association of PCOS with birth outcomes in the offspring of women with PCOS overall and by potential confounders. This systematic review and meta-analysis included 73 studies and 92,881 offspring of women with and without PCOS from inception until 13th July 2022. We report that mothers with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of preterm birth, fetal growth restriction and low birth weight are higher and mean birthweight is lower in PCOS of which a lower mean birthweight and a higher small for gestational age are probably independent of BMI. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured at pregnancy to identify risk and improve birth outcomes in the offspring.

External validation of risk prediction model for gestational diabetes: Individual participant data meta-analysis of randomized trials.

BACKGROUND: An original validated risk prediction model with good discriminatory prognostic performance for predicting gestational diabetes (GDM) diagnosis, has been updated for recent international association of diabetes in pregnancy study group (IADPSG) diagnostic criteria. However, the updated model is yet to be externally validated on an international dataset. AIMS: To perform an external validation of the updated risk prediction model to evaluate model indices such as discrimination and calibration based on data from the International Weight Management in Pregnancy (i-WIP) Collaborative Group. MATERIALS AND METHODS: The i -WIP dataset was used to validate the GDM prediction tool across discrimination and model calibration. RESULTS: Overall 7689 individual patient data were included, with 17.4 % with GDM, however only 113 cases were available using IADPSG (International Association of Diabetes and Pregnancy Groups) criteria for 75 g OGTT glucose load and ACOG (American College of Obstetricians and Gynecologists) for 100 g glucose load and having the routine clinical risk factor data. The GDM model was moderately discriminatory (Area Under the Curve (AUC) of 0.67; 95 % CI 0.59 to 0.75), Sensitivity 81.0 % (95 % CI 66.7 % to 90.9 %), specificity 53 % (40.3 % to 65.4 %). The GDM score showed reasonable calibration for predicting GDM (slope = 0.84, CITL = 0.77). Imputation for missing data increased the sample to n = 253, and vastly improved the discrimination and calibration of the model to AUC = 78 (95 % CI 72 to 85), sensitivity (81 %, 95 % CI 66.7 % to 90.9 %) and specificity (75 %, 95 % CI 68.8 % to 81 %). CONCLUSION: The updated GDM model showed promising discrimination in predicting GDM in an international population sourced from RCT individual patient data. External validations are essential in order for the risk prediction area to advance, and we demonstrate the utility of using existing RCT data from different global settings. Despite limitations associated with harmonising the data to the variable types in the model, the validation model indices were reasonable, supporting generalizability across continents and populations.

Exploring type 2 diabetes self-management practices in rural Bangladesh: facilitators, barriers and expectations-a qualitative study protocol.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a global public health crisis impacting low-income and middle-income countries such as Bangladesh. While self-management is encouraged for individuals with T2DM, there is a significant lack of knowledge regarding the factors of facilitators, barriers and expectations associated with T2DM self-management in Bangladesh. This research aims to investigate the potential elements that support, impede and are anticipated in the effective practice of self-management for T2DM in rural areas of Bangladesh. METHODS AND ANALYSIS: This study will use an exploratory qualitative approach. 16 focus group discussions, 13 in-depth interviews and 9 key informant interviews will be conducted among multilevel stakeholders, including people with T2DM, their caregivers, healthcare providers, health managers/administrators and policy planners. Interviews will be audio-recorded, transcribed, translated and analysed using thematic analysis. ETHICS AND DISSEMINATION: This research project has been approved by the Monash University Human Research Ethics Committee (project reference number: 39483) and the Ethical Review Committee of the Centre for Injury Prevention and Research, Bangladesh (Memo: CIPRB/ERC/2023/14). Research findings will be disseminated in peer-reviewed journals and conference presentations. Published reports will include group data. Individual data privacy will be strictly maintained.

Health System and Individual Barriers to Supporting Healthy Gestational Weight Gain and Nutrition: A Qualitative Study of the Experiences of Midwives and Obstetricians in Publicly Funded Antenatal Care in Tasmania, Australia.

Individual and health system barriers can impede clinicians from supporting weight-related behaviour change for pregnant women, particularly in publicly funded antenatal care accessed by women from diverse socioeconomic backgrounds. The aim was to understand clinicians' experiences of supporting healthy gestational weight gain for pregnant women in a publicly funded antenatal setting. The work was undertaken to guide the implementation of systems changes, resource development, and workforce capacity building related to nutrition, physical activity, and gestational weight gain in the service. The qualitative descriptive study used purposive sampling and semi-structured interviews conducted between October 2019 and February 2020. Nine midwives and five obstetricians from a publicly funded hospital antenatal service in Tasmania, Australia participated. Interview transcripts were analysed using inductive thematic analysis. The three dominant themes were prioritising immediate needs, continuity of care support weight-related conversations, and limited service capacity for weight- and nutrition-related support. The subthemes were different practices for women according to weight and the need for appropriately tailored resources. Improving access to continuity of care and clinician training, and providing resources that appropriately consider women's socioeconomic circumstances and health literacy would enhance the ability and opportunities for clinicians to better support all women.

Supporting the next generation of prevention research leaders to conduct effective research-policy partnerships.

Successful research-policy partnerships rely on shared vision, dedicated investment, and mutual benefits. To ensure the ongoing value of chronic disease prevention research, and support research translation and impact, Australia needs funding, university, and policy systems that incentivise and support emerging leaders to drive effective partnerships.

Consumer and community involvement in preventive health: current insights and considerations for future best practice.

Consumer and community involvement (CCI) in preventive research and health initiatives is not only encouraged but is expected within a rapidly evolving landscape across health policy, practice and research. Here, we summarise the fundamental principles of CCI, as well as outline the barriers and current developments in working towards best practices at organisational and systems levels. CCI stands at a critical juncture. Best practice emphasises meaningful partnerships with consumers and communities to deliver impactful research and prevention activities, yet complex challenges and systematic barriers remain. We need further evidence to demonstrate both 'what' and 'how' CCI should be best implemented in these settings. We present key considerations for researchers, organisations and systems to catalyse the transition of CCI from mere recognition of its importance to pragmatic and optimum implementation and, ultimately, to systemic reform. These include changes to capacity building, funding structures, equitable engagement and transparent evaluation. These must be underpinned by evidence-based approaches, partnership, trust and broad consensus processes to achieve meaningful and impactful CCI in research and healthcare improvement through a lens of inclusivity.

OptimalMe Program: A Mixed Method Investigation into the Engagement and Acceptability of a Preconception Digital Health Lifestyle Intervention with Individual Coaching for Women's Health and Behaviour Change.

Preconception interventions, specifically addressing general health, lifestyle behaviours and weight management, are limited despite their importance in optimising women's health. The objective of this study is to evaluate the engagement and acceptability of OptimalMe, a digital preconception intervention. Participants, (n = 298) Australian women aged 18-44 with private health insurance planning to conceive within 12 months, received a standardised intervention, including access to a digital healthy lifestyle platform (educational materials, behaviour change activities, and self-monitoring resources), ongoing text messaging, and remotely delivered health coaching (two appointments) with randomised delivery methods (telephone/videoconference). Engagement and acceptability were assessed through mixed method analyses. The results show that 76.2% attended both coaching sessions, with similar participation rates for telehealth (75.2%) and videoconferencing (77.2%) (p = 0.469). All participants logged into the digital platform, with 90.6% accessing educational materials and 91.3% using behaviour change tools. Digital platform engagement declined over time, suggesting potential benefits from additional health coaching support for ongoing participation. The post-intervention evaluation (n = 217 participants) demonstrated that approximately 90% found the digital module engaging, meeting information needs, would recommend the program, and were satisfied with the support. OptimalMe demonstrated positive acceptability and engagement; however, further research is warranted to explore strategies for sustaining engagement with the digital interventions.

The effectiveness of diabetes self-management education intervention on glycaemic control and cardiometabolic risk in adults with type 2 diabetes in low- and middle-income countries: A systematic review and meta-analysis.

Diabetes mellitus (DM) poses a significant challenge to public health. Effective diabetes self-management education (DSME) interventions may play a pivotal role in the care of people with type 2 diabetes mellitus (T2DM) in low- and middle-income countries (LMICs). A specific up-to-date systematic review is needed to assess the effect of DSME interventions on glycaemic control, cardiometabolic risk, self-management behaviours, and psychosocial well-being among T2DM across LMICs. The MEDLINE, Embase, CINAHL, Global Health, and Cochrane databases were searched on 02 August 2022 and then updated on 10 November 2023 for published randomised controlled trials (RCTs) and quasi-experimental studies. The quality of the studies was assessed, and a random-effect model was used to estimate the pooled effect of diabetes DSME intervention. Heterogeneity (I2) was tested, and subgroup analyses were performed. Egger's regression test and funnel plots were used to examine publication bias. The risk of bias of the included studies was assessed using the Cochrane risk-of-bias tool for randomized trial (RoB 2). The overall assessment of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. A total of 5893 articles were retrieved, and 44 studies (n = 11838) from 21 LMICs met the inclusion criteria. Compared with standard care, pooled analysis showed that DSME effectively reduced the HbA1c level by 0.64% (95% CI: 0.45% to 0.83%) and 1.27% (95% CI: -0.63% to 3.17%) for RCTs and quasi-experimental design studies, respectively. Further, the findings showed an improvement in cardiometabolic risk reduction, diabetes self-management behaviours, and psychosocial well-being. This review suggests that ongoing support alongside individualised face-to-face intervention delivery is favourable for improving overall T2DM management in LMICs, with a special emphasis on countries in the lowest income group.

Evaluating Preconception Health and Behaviour Change in Australian Women Planning a Pregnancy: The OptimalMe Program, a Digital Healthy Lifestyle Intervention with Remotely Delivered Coaching.

OptimalMe is a digital healthy lifestyle intervention for women planning a pregnancy, with remotely delivered coaching. This follow-up study of Australian women, stratified by coaching delivery mode (phone vs. videoconferencing), assessed alignment to preconception care guidelines and self-reported behaviour change. Overall, 298 women enrolled with a mean (SD) age of 31.8 (4.3) years and mean BMI of 25.7 (6.1) kg/m2. Suboptimal preconception behaviours were reported at baseline, including alcohol consumption (57.2%), infrequent weighing (37.2%) and incomplete cervical cancer screening (15.8%) and prenatal supplementation (38.5). At follow-up (4.5 months) (n = 217), a statistically significant shift towards desired behaviours was reported for alcohol consumption (z = -2.6045, p = 0.00932), preconception supplementation (z = -2.7288, p = 0.00634) and frequent weight monitoring (z = -5.2911, p < 0.00001). An insignificant shift towards adherence to cervical cancer screening (z = -1.8679, p = 0.06148) was observed, with a positive trend towards adherence. Results indicate that women who are actively planning a pregnancy require support to optimise health and lifestyle in preparation for pregnancy and general health and lifestyle improvement. Women demonstrated improvement in lifestyle behaviours and self-monitoring, indicating the uptake of low-intensity, non-prescriptive information provision. Supporting the provision of knowledge-enhancing tools and general healthy lifestyle information combines with skilled health coaching as an effective method for behaviour change and self-management. OptimalMe also shows significant improvements in rates of healthcare engagement, which suggests coaching-based digital health interventions may decrease women's barriers for preconception care and improve engagement in clinical settings.

Safety considerations for assessing the quality of apps used during pregnancy: A scoping review.

Objective: Pregnant women are increasingly turning to apps targeting knowledge and behaviour change for supporting healthy lifestyles and managing medical conditions. Yet, there is growing concern over the credibility and safety of content within mobile health (mHealth) apps. This scoping review aimed to systematically and thematically consolidate safety considerations described in reviews evaluating pregnancy-specific apps. Methods: PubMed, Ovid MEDLINE® and EPub, CINAHL, Web of Science, Cochrane Libraries, and SCOPUS were systematically searched to identify reviews that assessed apps targeting pregnant women. Data related to safety were extracted and thematically analysed to establish a set of relevant safety considerations. Results: Sixteen reviews met the inclusion criteria. The included reviews assessed an average of 27 apps each and targeted pregnancy topics, such as nutrition and physical activity. Five major and 20 minor themes were identified, including information, transparency, credibility, privacy and security, and app tailoring. Information, transparency, and credibility relate to the evidence base of information within the app, privacy and security of apps relate to the protection of personal information and data, and app tailoring relates to the consideration of contextual factors, such as local guidelines and digital health literacy. Conclusions: Results present possible safety considerations when evaluating pregnancy-specific apps and emphasise a clear need for consumer guidance on how to make informed decisions around engagement and use of mHealth apps during pregnancy.

High prevalence of medical conditions and unhealthy lifestyle behaviours in women with PCOS during preconception: findings from the Australian Longitudinal Study on Women's Health.

STUDY QUESTION: What are the pre-existing medical conditions and lifestyle behaviours of women with and without PCOS during the preconception period? SUMMARY ANSWER: During the preconception period, medical conditions of obesity, depression, anxiety, and a history of infertility were more highly prevalent in women with than without PCOS, and more women with than without PCOS were engaged in unhealthy lifestyle behaviours. WHAT IS KNOWN ALREADY: Women with PCOS are predisposed to infertility and pregnancy complications. Optimizing preconception medical health and lifestyle behaviours can improve maternal and pregnancy outcomes but, to the best of our knowledge, no study has examined the preconception medical conditions and lifestyle behaviours of women with PCOS. STUDY DESIGN, SIZE DURATION: This is a cross-sectional study on 942 women with PCOS and 7024 women without PCOS, aged 24-30 years from the Australian Longitudinal Study of Women's Health, an ongoing, national survey-based prospective cohort study. PARTICIPANTS/MATERIALS, SETTING, METHODS: The current study analysed self-reported data from Survey 6 collected in 2019 of the cohort of women born between 1989 and 1995. Explored outcomes included BMI, pre-existing medical conditions, and modifiable lifestyle behaviours, including smoking, recreational drug use, alcohol intake, and physical activity level, during the preconception period. Differences between subgroups were tested using Student's t-test, χ2 test, or Fisher's exact test as appropriate. The associations of pregnancy intention with medical conditions and lifestyle behaviours were examined using logistic regression. MAIN RESULTS AND THE ROLE OF CHANCE: Obesity, depression, anxiety, and infertility were highly prevalent in women actively planning for pregnancy. Among women with PCOS, the prevalence of obesity was 47.02%, followed by depression at 32.70%, anxiety at 39.62%, and infertility at 47.17%. Conversely among women without PCOS, the corresponding prevalence was lower, at 22.33% for obesity, 18.98% for depression, 23.93% for anxiety, and 16.42% for infertility. In women actively planning for pregnancy, only those without PCOS demonstrated a lower prevalence of unhealthy lifestyle behaviours compared to non-planning women. The prevalence of unhealthy lifestyle behaviours was similar in women with PCOS regardless of their pregnancy intentions. Multivariable logistic regression revealed that only moderate/high stress with motherhood/children (adjusted odds ratio (OR) 3.31, 95% CI 1.60-6.85) and history of infertility (adjusted OR 9.67, 95% CI 5.02-18.64) were significantly associated with active pregnancy planning in women with PCOS. LIMITATIONS, REASONS FOR CAUTION: The findings were based on self-reported data. The cohort of women surveyed may have a higher level of education than women in the community, therefore our findings may underestimate the true prevalence of pre-existing medical conditions and lifestyle challenges faced by the broader population. WIDER IMPLICATIONS OF THE FINDINGS: A higher proportion of women with than without PCOS had pre-existing medical conditions and engaged in potentially modifiable unhealthy lifestyle behaviours during preconception despite their risk for subfertility and pregnancy complications. Healthcare professionals play a pivotal role in guiding this high-risk group of women during this period, offering counselling, education, and support for the adoption of healthy lifestyles to improve fertility, pregnancy outcomes, and intergenerational health.

Key Components of Antenatal Lifestyle Interventions to Optimize Gestational Weight Gain: Secondary Analysis of a Systematic Review.

Importance: Randomized clinical trials have found that antenatal lifestyle interventions optimize gestational weight gain (GWG) and pregnancy outcomes. However, key components of successful interventions for implementation have not been systematically identified. Objective: To evaluate intervention components using the Template for Intervention Description and Replication (TIDieR) framework to inform implementation of antenatal lifestyle interventions in routine antenatal care. Data Sources: Included studies were drawn from a recently published systematic review on the efficacy of antenatal lifestyle interventions for optimizing GWG. The Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Health Technology Assessment Database, MEDLINE, and Embase were searched from January 1990 to May 2020. Study Selection: Randomized clinical trials examining efficacy of antenatal lifestyle interventions in optimizing GWG were included. Data Extraction and Synthesis: Random effects meta-analyses were used to evaluate the association of intervention characteristics with efficacy of antenatal lifestyle interventions in optimizing GWG. The results are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Data extraction was performed by 2 independent reviewers. Main Outcomes and Measures: The main outcome was mean GWG. Measures included characteristics of antenatal lifestyle interventions comprising domains related to theoretical framework, material, procedure, facilitator (allied health staff, medical staff, or researcher), delivery format (individual or group), mode, location, gestational age at commencement (<20 wk or ≥20 wk), number of sessions (low [1-5 sessions], moderate [6-20 sessions], and high [≥21 sessions]), duration (low [1-12 wk], moderate [13-20 wk], and high [≥21 wk]), tailoring, attrition, and adherence. For all mean differences (MDs), the reference group was the control group (ie, usual care). Results: Overall, 99 studies with 34 546 pregnant individuals were included with differential effective intervention components found according to intervention type. Broadly, interventions delivered by an allied health professional were associated with a greater decrease in GWG compared with those delivered by other facilitators (MD, -1.36 kg; 95% CI, -1.71 to -1.02 kg; P < .001). Compared with corresponding subgroups, dietary interventions with an individual delivery format (MD, -3.91 kg; 95% CI -5.82 to -2.01 kg; P = .002) and moderate number of sessions (MD, -4.35 kg; 95% CI -5.80 to -2.89 kg; P < .001) were associated with the greatest decrease in GWG. Physical activity and mixed behavioral interventions had attenuated associations with GWG. These interventions may benefit from an earlier commencement and a longer duration for more effective optimization of GWG. Conclusions and Relevance: These findings suggest that pragmatic research may be needed to test and evaluate effective intervention components to inform implementation of interventions in routine antenatal care for broad public health benefit.

Impact of COVID-19 Restriction on Weight, Physical Activity, Diet and Psychological Distress on People with PCOS.

BACKGROUND: People with polycystic ovary syndrome (PCOS) have higher weight gain and psychological distress compared to those without PCOS. While COVID-19 restrictions led to population level adverse changes in lifestyle, weight gain and psychological distress, their impact on people with PCOS is unclear. The aim of this study was to investigate the impact the 2020 COVID-19 restrictions had on weight, physical activity, diet and psychological distress for Australians with PCOS. METHODS: Australian reproductive-aged women participated in an online survey with assessment of weight, physical activity, diet and psychological distress. Multivariable logistic and linear regression were used to examine associations between PCOS and residential location with health outcomes. RESULTS: On adjusted analysis, those with PCOS gained more weight (2.9%; 95% CI; 0.027-3.020; p = 0.046), were less likely to meet physical activity recommendations (OR 0.50; 95% CI; 0.32-0.79; p = 0.003) and had higher sugar-sweetened beverage intake (OR 1.74; 95% CI 1.10-2.75; p = 0.019) but no differences in psychological distress compared to women without PCOS. CONCLUSIONS: People with PCOS were more adversely affected by COVID-19 restrictions, which may worsen their clinical features and disease burden. Additional health care support may be necessary to assist people with PCOS to meet dietary and physical activity recommendations.

Dissemination of public health research to prevent non-communicable diseases: a scoping review.

BACKGROUND: Dissemination is a critical element of the knowledge translation pathway, and a necessary step to ensure research evidence is adopted and implemented by key end users in order to improve health outcomes. However, evidence-based guidance to inform dissemination activities in research is limited. This scoping review aimed to identify and describe the scientific literature examining strategies to disseminate public health evidence related to the prevention of non-communicable diseases. METHODS: Medline, PsycInfo and EBSCO Search Ultimate were searched in May 2021 for studies published between January 2000 and the search date that reported on the dissemination of evidence to end users of public health evidence, within the context of the prevention of non-communicable diseases. Studies were synthesised according to the four components of Brownson and colleagues' Model for Dissemination of Research (source, message, channel and audience), as well as by study design. RESULTS: Of the 107 included studies, only 14% (n = 15) directly tested dissemination strategies using experimental designs. The remainder primarily reported on dissemination preferences of different populations, or outcomes such as awareness, knowledge and intentions to adopt following evidence dissemination. Evidence related to diet, physical activity and/or obesity prevention was the most disseminated topic. Researchers were the source of disseminated evidence in over half the studies, and study findings/knowledge summaries were more frequently disseminated as the message compared to guidelines or an evidence-based program/intervention. A broad range of dissemination channels were utilised, although peer-reviewed publications/conferences and presentations/workshops predominated. Practitioners were the most commonly reported target audience. CONCLUSIONS: There is a significant gap in the peer reviewed literature, with few experimental studies published that analyse and evaluate the effect of different sources, messages and target audiences on the determinants of uptake of public health evidence for prevention. Such studies are important as they can help inform and improve the effectiveness of current and future dissemination practices in public health contexts.

Ethnic Differences in Preferences for Lifestyle Intervention among Women after Childbirth: A Multi-Methods Study in Australia.

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.

Systematic review on the cost and cost-effectiveness of mHealth interventions supporting women during pregnancy.

OBJECTIVES: The increased integration of digital health into maternity care-alongside growing use of, and access to, personal digital technology among pregnant women-warrants an investigation of the cost-effectiveness of mHealth interventions used by women during pregnancy and the methodological quality of the cost-effectiveness studies. METHODS: A systematic search was conducted to identify peer-reviewed studies published in the last ten years (2011-2021) reporting on the costs or cost-effectiveness of mHealth interventions used by women during pregnancy. Available data related to program costs, total incremental costs and incremental cost-effectiveness ratios (ICERs) were reported in 2020 United States Dollars. The quality of cost-effectiveness studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). FINDINGS: Nine articles reporting on eight studies met the inclusion criteria. Direct intervention costs ranged from $7.04 to $86 per woman, total program costs ranged from $241,341 to $331,136 and total incremental costs ranged from -$21.16 to $1.12 million per woman. The following ICERs were reported: $2168 per DALY averted, $203.44 per woman ceasing smoking, and $3475 per QALY gained. The full economic evaluation studies (n = 4) were moderate to high in quality and all reported the mHealth intervention as cost-effective. Other studies (n = 4) were low to moderate in quality and reported low costs or cost savings associated with the implementation of the mHealth intervention. CONCLUSIONS FOR PRACTICE: Preliminary evidence suggests mHealth interventions may be cost-effective and "low-cost" but more evidence is needed to ascertain the cost-effectiveness of mHealth interventions regarding positive maternal and child health outcomes and longer-term health service utilisation.

Australian women's information-seeking preferences and needs in preparation for pregnancy.

ISSUE ADDRESSED: The preconception period provides opportunities for health behaviour optimisation for improved maternal and child well-being. However, preconception information sources women engage with are not well-known. METHODS: To address this gap, the current cross-sectional study retrospectively explored (1) preconception information or advice accessed on recommended preconception health topics and (2) preferred sources of preconception information amongst pregnant women receiving care through Australian public and private maternity settings. RESULTS: Overall, 78% of women reported accessing any preconception health information, predominantly concerning achieving/maintaining a healthy weight, diet, folic acid and multivitamin supplementation. Preferred information sources included health professionals, e.g. general practitioners (74%) and the internet (66%), although source engagement varied. CONCLUSIONS: Whilst women predominantly prefer seeking preconception health information from health professionals and the internet, multi-modal resources are needed to reach women and enhance engagement with evidence-based information and healthcare in preparation for pregnancy. SO WHAT?: Evaluation of preconception health resources for women and health professionals is warranted, appraising their adequacy in supporting engagement with key preconception health messages. In particular, assessment of the quality, readability and evidence-base of online resources is needed. Our findings highlight the need for public health experts to take action to raise awareness amongst women of the importance of preconception health, encourage health professional engagement for preconception care and direct women to more appropriate evidence-based online resources.

Recommendations for weight management in osteoarthritis: A systematic review of clinical practice guidelines.

Objective: While targeting obesity is central to osteoarthritis management, recent meta-analyses demonstrate only modest effects of weight loss on symptoms, and little on structure. The World Health Organisation recommends that effective management of obesity include prevention of weight gain, weight maintenance and weight loss. Therefore, we systematically reviewed the recommendations and approaches for management of obesity in clinical practice guidelines (CPGs) for osteoarthritis. Design: Nine databases were searched (01.01.2010-15.03.2022) to identify guidelines informing the non-pharmacological management of osteoarthritis. Three reviewers appraised guidelines according to the AGREE II instrument, and independently extracted data on their characteristics. One author extracted and summarised guideline recommendations on weight management. This systematic review is registered on PROSPERO (CRD42021274195). Results: Of the included fifteen CPGs (median AGREE II domain score 78.7%), weight loss was recommended for knee (12 of 13) and hip (10 of 11) but not hand (0 of 4) osteoarthritis. Combination approaches of diet and/or exercise were recommended for overweight or obese individuals in knee (8 of 12) and hip (4 of 10) osteoarthritis. Two guidelines specified ≥5% weight loss. One guideline specified strategies for maintenance of lost weight; none specifically recommended preventing weight gain. There was discordance between strength of recommendation for weight loss and level of evidence (3 of 15). Conclusion: Most CPGs for knee and hip osteoarthritis recommend weight loss to manage obesity in osteoarthritis. As steady weight accumulation is common in adults, preventing weight gain should also be considered as it is a missed opportunity to improve outcomes in osteoarthritis.
