Quality evaluation of nutrition policies in early childhood education and care services in Nerang, QLD.

ISSUE ADDRESSED: Food environments in early childhood, such as early childhood education and care services, influence the development of dietary patterns and behaviours that traverse into adulthood, where they affect health and longevity. Nutrition policies are mandatory in early childhood education and care services in Australia and can positively or negatively shape the food environment. However, the quality of such nutrition policies is unknown. This study aimed to evaluate the comprehensiveness and strength of nutrition policies of early childhood education and care services among services participating in a university-community alliance in South East Queensland. METHODS: Early childhood education and care services (n = 12) in Nerang, Queensland, Australia, participated in a cross-sectional study evaluating the comprehensiveness and strength of nutrition policies across four domains (Nutrition Education, Nutrition Standards, Promoting Healthy Eating and Communication and Evaluation) of the Wellness in Child Care Assessment Tool. RESULTS: Nutrition policies evaluated in this study had median total comprehensiveness scores of 55 (out of 100) and median total strength scores of 19 (out of 100). 'Nutrition Education' had the highest median scores for comprehensiveness (67 out of 100) and strength (33 out of 100), while 'Nutrition Standards' had the lowest comprehensiveness score (41 out of 100), and 'Communication and Evaluation' had the lowest strength score (0 out of 100). CONCLUSIONS: All services have a nutrition policy, but there are opportunities to enhance both the content and linguistic strength of statements within policies related to nutrition domains. SO WHAT?: There is a clear need to improve the comprehensiveness and strength of written statements in nutrition policies across all four domains, particularly 'Nutrition Standards' and 'Communication and Evaluation'.

Effectiveness of Interventions Promoting Dietary Intake, Physical Activity, and Healthy Weight Status of Children in Family Child Care: A Systematic Review.

INTRODUCTION: This systematic review examines the effectiveness of interventions in family child care (FCC) on (1) children's dietary intake, physical activity levels and weight, and (2) FCC health-promoting environments, policies, and practices. Quasi-experimental studies measuring these outcomes were included. METHODS: All available articles up to July 2023 were searched using MEDLINE, ERIC, CINAHL, Embase, Scopus, and A+ Education, and 15 interventions were included. Methodological quality was assessed with the Effective Public Health Practice Project Assessment tool. RESULTS: Thirteen studies were weak, and 2 strong in quality. Four interventions included children's dietary intake as an outcome measure, 2 included physical activity, and 3 weight status. Twelve interventions assessed nutrition and 7 physical activity environmental outcomes. DISCUSSION: Interventions in FCC improved children's dietary intake, but their impact on physical activity and weight status was inconclusive. Furthermore, positive impacts were observed in environmental outcomes related to nutrition, whereas research on physical activity environmental outcomes was limited. IMPLICATIONS FOR RESEARCH AND PRACTICE: Future research could replicate interventions to validate effectiveness and understand positive outcome mechanisms. Future interventions might use FCC stakeholders' input, incorporate innovative physical activity components, enhance FCC providers' position as role models, involve parents, and target those groups that are at a high risk of being obese.

Barriers and enablers to a healthy food environment in Australian childcare services: Exploring directors' perspectives.

ISSUE ADDRESSED: Early childhood education and care (ECEC) settings are ideal environments to optimise nutrition and positively influence children's food behaviours. However, recent research has identified the need to improve nutrition policies, food provision, and mealtime environments in Australian ECEC settings. This study explored the perceptions of ECEC directors regarding barriers and enablers to a health-promoting food environment within ECEC services. METHODS: Eleven directors from ECEC services in Nerang, Queensland, and surrounding areas, participated in qualitative interviews between March and May 2021. Transcripts were analysed using qualitative content analysis that followed a deductive-inductive approach employing nutrition-related domains from the Wellness Child Care Assessment Tool, these being: (i) nutrition policy; (ii) nutrition education; (iii) food provision; and (iv) mealtimes. Transcripts were coded independently by two researchers in NVivo and consensus for barriers and enablers was achieved through discussion. RESULTS: Barriers and enablers were reported across four domains (nutrition policy, nutrition education, food provision, and mealtimes). Comprehensive nutrition-related policies were an enabler to a healthy nutrition environment but were sometimes described as lacking detail or customisation to the service. Nutrition education for children was described as competing with other activities for time and resources in an already-crowded curriculum. Financial and time pressures faced by families were a barrier to healthy food provision in services where families provided food for children. The ability of staff to sit with children and engage in conversation during mealtimes was an enabler; however, competing demands on time and the unavailability of food for staff were cited as barriers to health-promoting mealtimes. CONCLUSIONS: Directors in ECEC services report both barriers and enablers to a healthy food environment. Nutrition policies were an enabler when comprehensive and relevant but a barrier when vague and not tailored to the service environment. ECEC services should be supported to develop and implement service-specific nutrition policies and practices by engaging with parents and staff. SO WHAT?: The barriers and enablers reported in this study should be considered when designing and implementing future evidence-based interventions to improve the nutrition environment in ECEC services.

How Can We Find Out What Indigenous Children and Their Families Need to Manage Weight? Lessons from Formative Nutrition Intervention Research with First Australians.

In Australia, Indigenous children have rates of overweight and obesity 1.5 times those of non-Indigenous children. Culturally safe and effective nutrition interventions are needed for this group. This paper aims to describe a Community-based Participatory Action Research (CPAR) approach to designing formative nutrition intervention research with First Australian children and their families and to reflect on the challenges arising from this process. After obtaining ethical approvals, a Steering Committee (SC), including nine Aboriginal and Torres Strait Islander people experienced in delivering or receiving health care, was established as a project governance body to develop culturally safe project materials and methods. The Indigenous research method of yarning circles was chosen by the SC for the community consultation, and the First Australian SC members were trained to collect the data. They liaised with community organizations to recruit yarning circle participants. Individual interviews conducted by an Aboriginal research assistant replaced yarning circles due to the COVID-19 pandemic lockdowns. While the CPAR approach to formative research was successful, the pandemic and other factors tripled the study duration. To authentically, ethically and safely engage First Australians in research, researchers need to decolonize their methodological approach, and funding bodies need to allow adequate time and resources for the process.

Telehealth interventions for physical activity and exercise participation in postpartum women: A quantitative systematic review.

Postpartum women are one of the least physically active vulnerable populations globally and telehealth has been proposed as a potential method of delivering effective exercise interventions for this population. However, clinical practice guidelines are based upon the recommendations for the general population and therefore, the most efficacious exercise dose and the delivery method for this population is unclear. This quantitative systematic review will examine the implementation and outcomes of telehealth exercise interventions in the postpartum population to synthesise the degree to which these outcomes have been assessed and evaluated. Five databases were searched from January 2001 to March 2022. Studies implementing synchronous telehealth exercise interventions for postpartum women were included. Interventions were examined against the Template for Intervention Description and Replication (TIDieR) checklist that assesses intervention reporting completeness and replicability. Of the 1036 records identified, 16 studies progressed to data extraction. Six interventions provided individualised exercise prescription, and only four were delivered by university-level exercise practitioners. Physical activity participation was well reported, however health-related outcomes (i.e., muscular strength and aerobic capacity) were very minimally assessed. Only one intervention utilised modern video conferencing as the primary telehealth communication method. With the minimal assessment of health-related outcomes, there is limited scope to assess the effectiveness of these interventions for postpartum women. Future research interventions need to be reported according to a validated trial reporting system and focus on relevant health related outcomes including postpartum depressive symptoms, quality of life, cardiovascular fitness, muscular strength and body composition.

Participatory design application in obesity prevention targeting young adults and adolescents: a mixed-methods systematic scoping review protocol.

BACKGROUND: Prevention of obesity is economically and sociologically preferable to treatment, with early intervention key to preventing excess weight gain and obesity. The transition from adolescence to young adulthood is a critical intervention period. An expert-led, top-down model has dominated obesity prevention research and practice with limited success. Participatory design (PD) offers potential in transforming obesity prevention research and practice by delivering bottom-up solutions that young people value and may therefore voluntarily engage with over time. An evidence synthesis of PD application in obesity prevention targeting adolescents and young adults is currently lacking. OBJECTIVES: Report the protocol for a mixed-methods systematic scoping review which aims to integrate and synthesise available evidence on PD application in obesity prevention targeting adolescents and young adults. Specifically, the review will address three research questions: RQ1: How is PD defined in obesity prevention interventions targeting adolescents and young adults? RQ2: To what extent is PD applied in obesity preventions interventions targeting adolescents and young adults? RQ3a: How is the utility of PD evaluated in obesity preventions interventions targeting adolescents and young adults? RQ3b: What is the utility of PD application in obesity prevention interventions targeting adolescents and young adults? METHODS: This mixed-methods systematic scoping review protocol adheres to the PRISMA-P guidelines and is informed by the PRISMA extension for scoping reviews (PRISMA-ScR). The search strategy and eligibility criteria are informed by the sample, phenomenon of interest, design, evaluation, and research type tool. Eligible studies will be peer-reviewed literature published in English, reporting on PD application in obesity prevention interventions (including intervention development, implementation, and/or evaluation) targeting adolescents and young adults (aged 10-35 years). Study designs will include qualitative, quantitative, and mixed methods. The review will comprise a systematic literature search, eligibility screening, data extraction, quality assessment using the Mixed-Methods Appraisal Tool (MMAT), and data analysis using an iterative narrative evidence synthesis approach. Evidence on PD application will be thematically integrated in terms of who was involved, when they were involved, and how and why they were involved. Further thematic analyses will be conducted according to the MATE taxonomy and the United Kingdom Medical Research Council (UK MRC's) key functions of process evaluations. The MATE taxonomy classifies PD application in terms of methodology, agent of change, training, and engagement. The MRC describes three functions of process evaluations: implementation, mechanisms of impact, and context. Applying both in the evidence synthesis is intended to provide a more complete picture of PD application. Exploratory analyses will be conducted to assess any potential associations between PD application and effectiveness across key outcomes (weight, physical activity, sedentary time, nutrition and dietary habit, mental health, and sleep) reported within intervention evaluations. CONCLUSIONS: Elucidating PD application is a prerequisite to establishing its utility. Through the location and synthesis of available evidence on PD application in obesity prevention targeting adolescents and young adults, this review will categorise and describe different methods of PD application and explore the utility of PD application including whether any differences may be observed between PD method applied and the effectiveness of obesity prevention interventions. Implications will be delineated from the narrative evidence synthesis to inform future research and advance practice in this context. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42021268240.

Postpartum nutrition: Guidance for general practitioners to support high-quality care.

BACKGROUND: General practitioners (GPs) are well placed to support new mothers with evidence-based nutrition care to eat well, live well and care for their new babies. Women who have recently given birth are highly motivated to eat well and seek information and support from GPs. OBJECTIVE: The aim of this article is to review current recommendations on dietary intake for women after birth and how GPs can use this information to inform high-quality ongoing care. DISCUSSION: The principles of healthy eating remain the same for all adults, and it is important that GPs support women to consume a wide variety of unprocessed, nutritious foods. Breastfeeding mothers require additional energy and nutrients such as protein, iodine, vitamin B12 and vitamin D, which are important in supporting healthy function and infant growth through breastmilk. GPs must take a person-centred approach to consultations, use respectful language and consider practical recommendations to support women in this exciting yet challenging time.

Addressing childhood obesity in Queensland: Aboriginal and Torres Strait Islander Health Worker perspectives and practices.

ISSUE ADDRESSED: Obesity disproportionately impacts Aboriginal and Torres Strait Islander children compared to non-Indigenous children. Aboriginal and Torres Strait Islander Health Workers (AHWs) in Queensland support the health of Aboriginal and Torres Strait Islander peoples. However, little is known about their perspectives and practices on addressing childhood obesity. The aim of this study was to investigate AHW perspectives and clinical practice behaviours with Aboriginal and Torres Strait Islander children and their families. METHODS: In a cross-sectional mixed-methods approach, a purpose-developed online survey (25 items) was distributed to the AHW workforce in Queensland (~100 AHWs). The survey explored [1] role characteristics, [2] current attitudes and beliefs about childhood obesity, [3] barriers to discussing weight management, [4] clinical practice behaviours and [5] demographic characteristics. Eight AHWs responding to the survey also participated in semi-structured telephone interviews to discuss their survey responses. RESULTS: Fifty-five AHWs responded and 45 completed the survey. While the majority of respondents (91%) agreed that addressing childhood obesity was an important part of their role, fewer (67%) agreed that obesity was an issue in Aboriginal and Torres Strait Islander peoples. Over half (55%) found it difficult to discuss overweight and obesity with children and families and only 22.5% reported measuring height and weight often. Key themes included a willingness to address childhood obesity, with experience and training being key enablers to discussing the issue. There was a perceived lack of culturally appropriate programs to support AHWs working with families. CONCLUSIONS: AHWs report a willingness to address childhood obesity within their roles, however many find it difficult to raise the issue with families, with even fewer routinely undertaking obesity assessment practices. SO WHAT?: These findings could inform training initiatives for AHWs to optimise screening, identification, referral, and treatment of childhood obesity in Aboriginal and Torres Strait Islander communities.

Evaluating Evidence-Based Content, Features of Exercise Instruction, and Expert Involvement in Physical Activity Apps for Pregnant Women: Systematic Search and Content Analysis.

BACKGROUND: Guidelines for physical activity and exercise during pregnancy recommend that all women without contraindications engage in regular physical activity to improve both their own health and the health of their baby. Many women are uncertain how to safely engage in physical activity and exercise during this life stage and are increasingly using mobile apps to access health-related information. However, the extent to which apps that provide physical activity and exercise advice align with current evidence-based pregnancy recommendations is unclear. OBJECTIVE: This study aims to conduct a systematic search and content analysis of apps that promote physical activity and exercise in pregnancy to examine the alignment of the content with current evidence-based recommendations; delivery, format, and features of physical activity and exercise instruction; and credentials of the app developers. METHODS: Systematic searches were conducted in the Australian App Store and Google Play Store in October 2020. Apps were identified using combinations of search terms relevant to pregnancy and exercise or physical activity and screened for inclusion (with a primary focus on physical activity and exercise during pregnancy, free to download or did not require immediate paid subscription, and an average user rating of ≥4 out of 5). Apps were then independently reviewed using an author-designed extraction tool. RESULTS: Overall, 27 apps were included in this review (Google Play Store: 16/27, 59%, and App Store: 11/27, 41%). Two-thirds of the apps provided some information relating to the frequency, intensity, time, and type principles of exercise; only 11% (3/27) provided this information in line with current evidence-based guidelines. Approximately one-third of the apps provided information about contraindications to exercise during pregnancy and referenced the supporting evidence. None of the apps actively engaged in screening for potential contraindications. Only 15% (4/27) of the apps collected information about the user's current exercise behaviors, 11% (3/27) allowed users to personalize features relating to their exercise preferences, and a little more than one-third provided information about developer credentials. CONCLUSIONS: Few exercise apps designed for pregnancy aligned with current evidence-based physical activity guidelines. None of the apps screened users for contraindications to physical activity and exercise during pregnancy, and most lacked appropriate personalization features to account for an individual's characteristics. Few involved qualified experts during the development of the app. There is a need to improve the quality of apps that promote exercise in pregnancy to ensure that women are appropriately supported to engage in exercise and the potential risk of injury, complications, and adverse pregnancy outcomes for both mother and child is minimized. This could be done by providing expert guidance that aligns with current recommendations, introducing screening measures and features that enable personalization and tailoring to individual users, or by developing a recognized system for regulating apps.

Do modifiable risk factors for cardiovascular disease post-pregnancy influence the association between hypertensive disorders of pregnancy and cardiovascular health outcomes? A systematic review of observational studies.

Hypertensive disorders of pregnancy (HDP) are associated with increased risk of developing cardiovascular disease (CVD) in later life. This systematic review aimed to evaluate the impact of modifiable risk factors for CVD following pregnancy on the relationship between HDP and cardiovascular health outcomes. Seven databases (Medline, CENTRAL, CINAHL, Cochrane Reviews, Embase, PsycINFO and Scopus) were searched from date of inception to July 24, 2019. Observational studies that included female adults with a history of HDP and analysed whether modifiable risk factors for CVD following pregnancy (dietary intake, physical activity, smoking status, alcohol intake, body weight and mental health status) influenced associations between HDP and cardiovascular health outcomes (morbidity, mortality or related risk markers) were eligible for inclusion. In total, 4704 articles were identified, with 11 studies included. The modifiable risk factors measured included body weight (11 studies), physical activity and dietary intake (one study) and smoking (one study). Overall, five of seven studies provided convincing evidence that the relationship between HDP and blood pressure was adversely impacted by excess body weight post-pregnancy. The current systematic review provides evidence that excess body weight post-pregnancy impacts associations between HDP and hypertension in later life. However, there is a lack of evidence exploring the impact of a variety of modifiable risk factors for CVD on associations between HDP and cardiovascular health outcomes. This evidence is imperative to inform development of effective CVD prevention interventions for women with a history of HDP.

Cultural adaptation of health interventions including a nutrition component in Indigenous peoples: a systematic scoping review.

BACKGROUND: Indigenous populations throughout the world experience poorer health outcomes than non-indigenous people. The reasons for the health disparities are complex and due in part to historical treatment of Indigenous groups through colonisation. Evidence-based interventions aimed at improving health in this population need to be culturally safe. However, the extent to which cultural adaptation strategies are incorporated into the design and implementation of nutrition interventions designed for Indigenous peoples is unknown. The aim of this scoping review was to explore the cultural adaptation strategies used in the delivery of nutrition interventions for Indigenous populations worldwide. METHODS: Five health and medical databases were searched to January 2020. Interventions that included a nutrition component aimed at improving health outcomes among Indigenous populations that described strategies to enhance cultural relevance were included. The level of each cultural adaptation was categorised as evidential, visual, linguistic, constituent involving and/or socio-cultural with further classification related to cultural sensitivity (surface or deep). RESULTS: Of the 1745 unique records screened, 98 articles describing 66 unique interventions met the inclusion criteria, and were included in the synthesis. The majority of articles reported on interventions conducted in the USA, Canada and Australia, were conducted in the previous 10 years (n = 36) and focused on type 2 diabetes prevention (n = 19) or management (n = 7). Of the 66 interventions, the majority included more than one strategy to culturally tailor the intervention, combining surface and deep level adaptation approaches (n = 51), however, less than half involved Indigenous constituents at a deep level (n = 31). Visual adaptation strategies were the most commonly reported (n = 57). CONCLUSION: This paper is the first to characterise cultural adaptation strategies used in health interventions with a nutrition component for Indigenous peoples. While the majority used multiple cultural adaptation strategies, few focused on involving Indigenous constituents at a deep level. Future research should evaluate the effectiveness of cultural adaptation strategies for specific health outcomes. This could be used to inform co-design planning and implementation, ensuring more culturally appropriate methods are employed.

Quality, Features, and Presence of Behavior Change Techniques in Mobile Apps Designed to Improve Physical Activity in Pregnant Women: Systematic Search and Content Analysis.

BACKGROUND: Physical activity during pregnancy is associated with several health benefits for the mother and child. However, very few women participate in regular physical activity during pregnancy. eHealth platforms (internet and mobile apps) have become an important information source for pregnant women. Although the use of pregnancy-related apps has significantly increased among pregnant women, very little is known about their theoretical underpinnings, including their utilization of behavior change techniques (BCTs). This is despite research suggesting that inclusion of BCTs in eHealth interventions are important for promoting healthy behaviors, including physical activity. OBJECTIVE: The aim of this study was to conduct a systematic search and content analysis of app quality, features, and the presence of BCTs in apps designed to promote physical activity among pregnant women. METHODS: A systematic search in the Australian App Store and Google Play store using search terms relating to exercise and pregnancy was performed. App quality and features were assessed using the 19-item Mobile App Rating Scale (MARS), and a taxonomy of BCTs was used to determine the presence of BCTs (26 items). BCTs previously demonstrating efficacy in behavior changes during pregnancy were also identified from a literature review. Spearman correlations were used to investigate the relationships between app quality, app features, and number of BCTs identified. RESULTS: Nineteen exercise apps were deemed eligible for this review and they were accessed via Google Play (n=13) or App Store (n=6). The MARS overall quality scores indicated moderate app quality (mean 3.5 [SD 0.52]). Functionality was the highest scoring MARS domain (mean 4.2 [SD 0.5]), followed by aesthetics (mean 3.7 [SD 0.6]) and information quality (mean 3.16 [SD 0.42]). Subjective app quality (mean 2.54 [SD 0.64]) and likelihood for behavioral impact (mean 2.5 [SD 0.6]) were the lowest scoring MARS domains. All 19 apps were found to incorporate at least two BCTs (mean 4.74, SD 2.51; range 2-10). However, only 11 apps included BCTs that previously demonstrated efficacy for behavior change during pregnancy, the most common being provide opportunities for social comparison (n=8) and prompt self-monitoring of behavior (n=7). There was a significant positive correlation between the number of BCTs with engagement and aesthetics scores, but the number of BCTs was not significantly correlated with functionality, information quality, total MARS quality, or subjective quality. CONCLUSIONS: Our findings showed that apps designed to promote physical activity among pregnant women were functional and aesthetically pleasing, with overall moderate quality. However, the incorporation of BCTs was low, with limited prevalence of BCTs previously demonstrating efficacy in behavior change during pregnancy. Future app development should identify and adopt factors that enhance and encourage user engagement, including the use of BCTs, especially those that have demonstrated efficacy for promoting physical activity behavior change among pregnant women.

Be Healthe for Your Heart: A Pilot Randomized Controlled Trial Evaluating a Web-Based Behavioral Intervention to Improve the Cardiovascular Health of Women with a History of Preeclampsia.

This pilot randomized controlled trial (RCT) aimed to determine the acceptability and preliminary efficacy of a web-based cardiovascular disease (CVD) prevention intervention for women following preeclampsia. Australian women with a recent history (≤4 years post diagnosis) of preeclampsia were randomized into two study arms: (1) Be Healthe for your Heart, a web-based behavioral intervention or; (2) Control, access to the National Heart Foundation website. Assessments were conducted at baseline, and after three months. Intervention acceptability and impact on absolute CVD 30-year risk score, CVD risk markers and health behaviors were assessed. Twenty-four of 31 (77.4%) women completed the three-month assessment. Eleven out of 13 intervention participants (84.6%) agreed/strongly agreed they were satisfied with the program, with a mean score of 4.2 ± 0.9 (maximum of five). There were no significant between or within group differences in absolute CVD risk, CVD risk markers or health behaviors from baseline to three months. Women with a history of preeclampsia were successfully recruited and retained and they reported high levels of acceptability with the Be Healthe for your Heart program. Further research is therefore needed from powered trials to determine the impact of web-based lifestyle interventions on CVD risk in this at-risk group.

Effect of micronutrient supplements on low-risk pregnancies in high-income countries: a systematic quantitative literature review.

OBJECTIVE: To assess the quantity and focus of recent empirical research regarding the effect of micronutrient supplementation on live birth outcomes in low-risk pregnancies from high-income countries. DESIGN: A systematic quantitative literature review. SETTING: Low-risk pregnancies in World Bank-classified high-income countries, 2019. RESULTS: Using carefully selected search criteria, a total of 2475 publications were identified, of which seventeen papers met the inclusion criteria for this review. Data contributing to nine of the studies were sourced from four cohorts; research originated from ten countries. These cohorts exhibited a large number of participants, stable data and a low probability of bias. The most recent empirical data offered by these studies was 2011; the most historical was 1980. In total, fifty-five categorical outcome/supplement combinations were examined; 67·3 % reported no evidence of micronutrient supplementation influencing selected outcomes. CONCLUSIONS: A coordinated, cohesive and uniform empirical approach to future studies is required to determine what constitutes appropriate, effective and safe micronutrient supplementation in contemporary cohorts from high-income countries, and how this might influence pregnancy outcomes.

Influence of dietary intake and decision-making during pregnancy on birth outcomes.

AIM: This study aimed to examine dietary intake and decision-making in a cohort of pregnant South-East Queensland women to determine compliance with dietary guidelines and the relationships between dietary intake, decision-making and birth outcomes. METHODS: Pregnant women attending maternity services at participating hospitals reported food frequency and motivations using the Maternal Outcomes and Nutrition Tool, a novel digital instrument. Birth outcomes were sourced from hospital records. A cross-sectional cohort design was used to examine the data. RESULTS: Analysis demonstrated suboptimal intake of core food groups; meat and alternatives (median [IQR]) (2.6 [2.0-3.4] serves/day) and grains (3.1 [2.1-4.1]) fell below recommendations; fruit (3.8 [2.5-5.3]) and discretionary foods (3.1 [2.1-4.4]) exceeded them. Hypertensive disorders demonstrated a negative linear relationship with vegetable intake (P = .017). Cultural diversity was significantly associated with decreased birthweight (P = .022) but increased intake of meat and alternatives (3.1 vs 2.6, P < .001) compared to Caucasian women; median intake of meat and alternatives was lower in women who reported smoking in the examined time frame. Smokers were less likely to declare health motives for food selection than non-smokers; smoking and health were inversely associated with increasing maternal age. Food choice was primarily sensory-driven. CONCLUSIONS: This cohort demonstrated poor adherence to dietary guidelines. Culturally and linguistically diverse women and smokers exhibit dietary behaviours which may contribute to suboptimal birth outcomes; targeted nutrition counselling may improve outcomes in these women. These findings highlight the need for transdisciplinary maternity care and provide a foundation for further research aimed at optimising nutrition-related birth outcomes in at-risk groups.

Supporting women of childbearing age in the prevention and treatment of overweight and obesity: a scoping review of randomized control trials of behavioral interventions.

BACKGROUND: Women of childbearing age are vulnerable to weight gain. This scoping review examines the extent and range of research undertaken to evaluate behavioral interventions to support women of childbearing age to prevent and treat overweight and obesity. METHODS: Eight electronic databases were searched for randomized controlled trials (RCT) or systematic reviews of RCTs until 31st January 2018. Eligible studies included women of childbearing age (aged 15-44 years), evaluated interventions promoting behavior change related to diet or physical activity to achieve weight gain prevention, weight loss or maintenance and reported weight-related outcomes. RESULTS: Ninety studies met the inclusion criteria (87 RCTs, 3 systematic reviews). Included studies were published from 1998 to 2018. The studies primarily focused on preventing excessive gestational weight gain (n = 46 RCTs, n = 2 systematic reviews), preventing postpartum weight retention (n = 18 RCTs) or a combination of the two (n = 14 RCTs, n = 1 systematic review). The RCTs predominantly evaluated interventions that aimed to change both diet and physical activity behaviors (n = 84) and were delivered in-person (n = 85). CONCLUSIONS: This scoping review identified an increasing volume of research over time undertaken to support women of childbearing age to prevent and treat overweight and obesity. It highlights, however, that little research is being undertaken to support the young adult female population unrelated to pregnancy or preconception.

Use of micronutrient supplements in pregnant women of south-east Queensland.

BACKGROUND: Multiple micronutrient supplement use in the Australian pregnant population is rising, despite little evidence of benefit in low-risk women. While some supplement recommendations are grounded in high-quality evidence, others warrant further investigation. This highlights a research gap regarding appropriate use of supplements during pregnancy in the Australian population. AIMS: To describe micronutrient supplement use during pregnancy in the context of current evidence and national recommendations in a population of south-east Queensland women. MATERIAL AND METHODS: A cross-sectional observational design was used to examine data gathered from pregnant women aged 16-44 years residing in south-east Queensland, Australia. Women were recruited to the study between 23 May 2016 and 30 September 2017. RESULTS: Pregnancy multivitamin use was declared by 42% of the cohort, with 26.8% declaring multivitamins in combination with individual micronutrients and 9.8% declaring specific micronutrient supplement use. Nulliparous women were more likely to declare use of supplements than their multiparous peers (adjusted odds ratio (aOR) 1.938, 95% CI 1.053-3.571, P = 0.034); smoking (aOR 2.717, 95% CI 1.011-7.302, P = 0.047) and low socio-economic status were associated with no supplement use (aOR 2.451, 95% CI 1.010-5.949, P = 0.048). CONCLUSIONS: Current recommendations regarding micronutrient supplements throughout pregnancy are based on varying degrees of evidence, resulting in supplement advice of poor cohesion and consistency. Adherence to micronutrient supplement recommendations in the peri-conception period in this population was poor; second and third trimester supplement use was high. Contemporary empirical research is required to determine what constitutes appropriate supplementation in high-income regions and the populations they will benefit most.

A review of pregnancy information on nutrition, physical activity and sleep websites.

PROBLEM: Most pregnant women report using the internet to source health information during pregnancy. However, little is known about the information presented on the internet and whether it is consistent with current evidence-based guidelines. BACKGROUND: Pregnancy is considered a risk period for women as it is associated with poorer health behaviours including an inadequate diet, decreased physical activity and reduced sleep. As a result, pregnant women and their unborn child are at a greater risk of adverse health outcomes. AIM: The purpose of this study was to review pregnancy related information about nutrition, physical activity and sleep provided on Australian government and leading industry body websites, and to compare this information to current evidence-based guidelines. METHODS: A systematic online search was conducted to identify Australian Government, and leading industry websites that provided information on nutrition, physical activity, or sleep during pregnancy. The content of each website was reviewed and compared against current nutrition, physical activity and sleep guidelines. FINDINGS: 27 government and leading industry websites were included in this study. 18 websites included nutritional information, none of which aligned 100% with guidelines. Nine websites included physical activity information, only one of which was 100% in accordance with guidelines. Two websites included information on sleep during pregnancy, however neither were in accordance with guidelines. CONCLUSION: Women are accessing information via the internet that is not in accordance with current evidence-based guidelines. These results call to attention the need for government and leading industry websites to review and update their website information in accordance with current evidence-based guidelines.

Be Healthe for Your Heart: Protocol for a Pilot Randomized Controlled Trial Evaluating a Web-Based Behavioral Intervention to Improve the Cardiovascular Health of Women With a History of Preeclampsia.

Background: Women with a history of preeclampsia are at greater risk of cardiovascular disease (CVD) related morbidity. Despite this knowledge, there is a lack of interventions available for women with a history of preeclampsia for the prevention of CVD. The aim of this pilot randomized controlled trial (RCT) is to determine the acceptability and preliminary efficacy of a web-based behavioral intervention targeted to women with a history of preeclampsia (Be Healthe for your Heart). Method: Australian women aged 18-45 years, with a recent history (≤4 years post diagnosis) of preeclampsia will be recruited for a 3-months, 2-arm parallel group pilot RCT. Participants will be randomized into 2 study arms: (1) Be Healthe for your Heart or; (2) Control, with assessments conducted at baseline, and after 3-months. Be Healthe for your Heart is an intervention delivered online via the program website, with weekly emails to support changes in modifiable CVD risk factors (excess body weight, physical inactivity, poor diet, and stress), using behavior change techniques (e.g., self-monitoring, goal setting). Intervention acceptability (satisfaction, usability, appropriateness, and usage) and impact on absolute full CVD 30-years risk score, CVD risk markers, and modifiable risk factors will be assessed. Discussion: No studies to date have evaluated acceptability and preliminary efficacy of a web-based intervention for the prevention of CVD in this high-risk population with preeclampsia. This pilot trial will inform development of a fully powered RCT if acceptability and preliminary efficacy are demonstrated.

Essential Mineral Intake During Pregnancy and Its Association With Maternal Health and Birth Outcomes in South East Queensland, Australia.

Micronutrient supplements are often recommended during pregnancy, yet their role and necessity remain poorly understood in the Australian population. This study aimed to determine the essential mineral intake of a population of pregnant women in South East Queensland and investigate the effects of supplements on their micronutrient status and birth outcomes. Women completing the Oral Glucose Tolerance Test at two South East Queensland hospitals between 180 and 210 days gestation provided fasting blood samples and dietary data using the Maternal Outcomes and Nutrition Tool (n = 127). Birth outcomes were sourced from medical records. Serum elemental profiles were determined by inductively coupled plasma mass spectrometry (ICP-MS) analysis. Intake of 8 essential minerals was compared with Australian dietary recommendations; matched serum mineral levels were compared with the current Queensland pregnancy reference ranges. Data were examined using cross-sectional cohort design and independent sample t-tests. Supplement use had no significant influence on serum values of trace elements or the incidence of hypertensive disorders, gestational diabetes, preterm birth or infant birthweight. Dietary selenium, zinc and iodine were significantly higher in women birthing beyond 41 completed weeks; selenium (P = .026) and zinc (P = .034) both made unique contributions to the regression models when controlling for confounders. Women exhibited adequate to excessive serum micronutrient levels compared with pregnancy reference ranges, a finding consistent with dietary intake calculations. Data suggest that excessive essential mineral intake contributed to prolonged pregnancy in this cohort, supporting previous studies in this population. Further research is required to determine individual needs and eliminate the potential for harm before recommending pregnancy supplements.
