RESUMO
Olive oil (OO) polyphenols have been shown to improve HDL anti-atherogenic function, thus demonstrating beneficial effects against cardiovascular risk factors. The aim of the present study was to investigate the effect of extra virgin high polyphenol olive oil (HPOO) v. low polyphenol olive oil (LPOO) on the capacity of HDL to promote cholesterol efflux in healthy adults. In a double-blind, randomised cross-over trial, fifty participants (aged 38·5 (sd 13·9) years, 66 % females) were supplemented with a daily dose (60 ml) of HPOO (320 mg/kg polyphenols) or LPOO (86 mg/kg polyphenols) for 3 weeks. Following a 2-week washout period, participants crossed over to the alternate treatment. Serum HDL-cholesterol efflux capacity, circulating lipids (i.e. total cholesterol, TAG, HDL, LDL) and anthropometrics were measured at baseline and follow-up. No significant between-group differences were observed. Furthermore, no significant changes in HDL-cholesterol efflux were found within either the LPOO and HPOO treatment arms; mean changes were 0·54 % (95 % CI (0·29, 1·37)) and 0·10 % (95 % CI (0·74, 0·94)), respectively. Serum HDL increased significantly after LPOO and HPOO intake by 0·13 mmol/l (95 % CI (0·04, 0·22)) and 0·10 mmol/l (95 % CI (0·02, 0·19)), respectively. A small but significant increase in LDL of 0·14 mmol/l (95 % CI (0·001, 0·28)) was observed following the HPOO intervention. Our results suggest that additional research is warranted to further understand the effect of OO with different phenolic content on mechanisms of cholesterol efflux via different pathways in multi-ethnic populations with diverse diets.

ISSUE ADDRESSED: Retention of weight gained during pregnancy contributes to overweight and obesity and consequent chronic disease risk. Early programs have been successful in improving diet quality, physical activity levels and reducing postnatal weight retention. However, barriers to program engagement remain. This study aimed to investigate women's healthy eating, physical activity and weight experiences and explore their views regarding digital health interventions to assist meeting their lifestyle goals. METHODS: This qualitative descriptive study utilised semi-structured interviews with women who had recently become mothers who had gestational diabetes or a body mass index above 25 kg/m2 . Themes were then identified through thematic analysis of interview transcripts. RESULTS: Nine women were interviewed (average age 33.4 ± 4.2 years). The two distinct areas of questioning resulted in two overarching topics: (i) Enablers and barriers to maintaining regular physical activity and a healthy dietary pattern; and (ii) characteristics of a postpartum program to enable meeting of diet, physical activity and weight loss goals. These topics each had their own descriptive themes and sub-themes. CONCLUSIONS: Understanding women's needs and viewpoints for a postnatal diet, physical activity and weight program allows researchers to design a program to maximise engagement and outcomes. SO WHAT?: Any further postnatal program must leverage off existing infrastructure, integrate learnings from published formative work and harnesses the impact of digital delivery. This will improve program accessibility and provide ongoing contact for sustained behaviour change through text messaging and providing digital resources in a dynamic format women can engage with in their own time.

PURPOSE: Olive oil polyphenols have been associated with cardiovascular health benefits. This study examined the antioxidant and anti-inflammatory effect of extra-virgin high polyphenol olive oil (HPOO) vs. low polyphenol olive oil (LPOO) in healthy Australian adults. METHODS: In a double-blind cross-over trial, 50 participants (aged 38.5 ± 13.9 years, 66% females) were randomized to consume 60 mL/day of HPOO (320 mg/kg polyphenols) or LPOO (86 mg/kg polyphenols) for three weeks. Following a 2-week wash-out period, participants crossed-over to the alternate treatment. Plasma oxidized low-density lipoprotein (ox-LDL), total antioxidant capacity (TAC), high-sensitivity C-reactive protein (hs-CRP) and anthropometrics were measured at baseline and follow-up. RESULTS: Fourty-three participants completed the study. Although there were no significant differences between treatments in the total sample, plasma ox-LDL decreased by 6.5 mU/mL (95%CI - 12.4 to - 0.5) and TAC increased by 0.03 mM (95% CI 0.006-0.05) only in the HPOO arm. Stratified analyses were also performed by cardiovascular disease risk status defined by abdominal obesity (WC > 94 cm in males, > 80 cm in females) or inflammation (hs-CRP > 1 mg/L). In the subgroup with abdominal obesity, ox-LDL decreased by 13.5 mU/mL (95% CI - 23.5 to - 3.6) and TAC increased by 0.04 mM (95% CI 0.006-0.07) only after HPOO consumption. In the subgroup with inflammation, hs-CRP decreased by 1.9 mg/L (95% CI - 3.7 to -0.1) only in the HPOO arm. CONCLUSIONS: Although there were no significant differences between treatments, the changes observed after HPOO consumption demonstrate the antioxidant and anti-inflammatory effect of this oil, which is more pronounced in adults with high cardiometabolic risk (Clinical Trial Registration: ACTRN12618000706279).

OBJECTIVE: Adequate and appropriate nutrition education is expected to contribute towards preventing risk of child stunting and maternal overweight/obesity. Understanding women's information-seeking behaviours is an important key step for health professionals and departments of health in order to improve the development of optimal and targeted nutrition education during pregnancy. This study investigated the experience of Indonesian women in seeking and receiving nutritional information during pregnancy and its relationship to women's socio-demographic and pregnancy characteristics. DESIGN: An online cross-sectional study. SETTING: Malang City, Indonesia. PARTICIPANTS: Women who had given birth within the past 2 years (n 335). RESULTS: All women in this study sought or received food and nutrition information from multiple sources, including social and health professional contacts and media sources. The women frequently discussed nutrition issues with their family, particularly their husband (98·2 %) and mother or mother-in-law (91·6 %). This study identified four groups of sources based on women's search habits. Women from high socio-economic strata were more likely to discuss food and nutrition issues or received nutrition information from obstetricians, their family or online sources (adjusted R2 = 26·3 %). Women from low socio-economic strata were more likely to receive nutrition information from midwives, health volunteers or Maternal and Child Health books (adjusted R2 = 14·5 %). CONCLUSIONS: A variety of nutrition information sources needs to be provided for women from different socio-economic strata. Involvement of family members in antenatal nutrition education may improve the communication and effectiveness of young mothers' dietary and nutrition education.

OBJECTIVE: Social media analytics (SMA) has a track record in business research. The utilisation in nutrition research is unknown, despite social media being populated with real-time eating behaviours. This rapid review aimed to explore the use of SMA in nutrition research with the investigation of dietary behaviours. DESIGN: The review was conducted according to rapid review guidelines by WHO and the National Collaborating Centre for Methods and Tools. Five databases of peer-reviewed, English language studies were searched using the keywords 'social media' in combination with 'data analytics' and 'food' or 'nutrition' and screened for those with general population health using SMA on public domain, social media data between 2014 and 2020. RESULTS: The review identified 34 studies involving SMA in the investigation of dietary behaviours. Nutrition topics included population nutrition health investigations, alcohol consumption, dieting and eating out of the home behaviours. All studies involved content analysis with evidence of surveillance and engagement. Twitter was predominant with data sets in tens of millions. SMA tools were observed in data discovery, collection and preparation, but less so in data analysis. Approximately, a third of the studies involved interdisciplinary collaborations with health representation and only two studies involved nutrition disciplines. Less than a quarter of studies obtained formal human ethics approval. CONCLUSIONS: SMA in nutrition research with the investigation of dietary behaviours is emerging, nevertheless, if consideration is taken with technological capabilities and ethical integrity, the future shows promise at a broad population census level and as a scoping tool or complementary, triangulation instrument.

There is a clear impetus for researchers to facilitate cross-sector and interdisciplinary collaboration to achieve collective action for maternal obesity prevention. Building early- and mid-career researchers' capacity to sustainably develop collective action into the future is key. Therefore, the national Health in Preconception, Pregnancy, and Postpartum Early- and Mid-career Researcher Collective (HiPPP EMR-C) was formed. Here, we describe the aim, key goals and future directions of the HiPPP EMR-C. Guided by the Simplified Framework for Understanding Collective Action, we aim to build our capacity as researchers, form policy stakeholder relationships and focus on generating impact to optimise maternal and child health and well-being.

Spontaneous preterm birth is the leading cause of neonatal mortality and morbidity globally. Activation of the maternal immune system leads to a downstream cascade of proinflammatory events that culminate in the activation of spontaneous uterine contractions and the rupture of the foetal membranes. Anti-inflammatory agents may be a novel therapeutic approach to prevent inflammation-induced myometrial contractions and premature rupture of foetal membranes. The polyphenol gallic acid has been previously shown to exert potent anti-inflammatory effects. Thus, this study aimed to determine the effect of gallic acid on proinflammatory and pro-labour mediators in cytokine-stimulated gestational tissues in vitro. In primary human cells isolated from myometrium and foetal membranes (decidua, and amnion mesenchymal and epithelial cells), gallic acid treatment suppressed inflammation-induced expression of proinflammatory cytokines and chemokines and extracellular matrix-degrading and matrix-remodelling enzymes. Gallic acid also significantly inhibited inflammation-induced myometrial activation as evidenced by decreased expression of contraction-associated proteins, the uterotonic PGF2α and collagen cell contractility. Using a global proteomic approach, gallic acid may differentially regulate proteins associated with collagen synthesis, cell contractility and protein synthesis in primary myometrial and decidual cells. In summary, gallic acid inhibited inflammation-induced mediators involved in active labour in primary cells isolated from myometrium and foetal membranes. These in vitro studies suggest that the polyphenol gallic acid may be able to suppress the production of proinflammatory and pro-labour mediators involved in myometrial contractions and rupture of foetal membranes. Future preclinical studies may elucidate the efficacy of gallic acid in preventing inflammation-driven preterm birth.

Gestational diabetes mellitus (GDM) is a global health issue, whereby pregnant women are afflicted with carbohydrate intolerance with first onset during pregnancy. GDM is characterized by maternal peripheral insulin resistance, thought to be driven by low-grade maternal inflammation. Nobiletin, a polymethoxylated flavonoid, possesses potent glucose-sensitizing and anti-inflammatory properties; however, its effects in GDM have not been assessed. The present study aimed to determine the effects of nobiletin on glucose metabolism and inflammation associated with GDM in both in vitro human tissues and an in vivo animal model of GDM. In vitro, treatment with nobiletin significantly improved TNF-impaired glucose uptake in human skeletal muscle, and suppressed mRNA expression and protein secretion of pro-inflammatory cytokines and chemokines in human placenta and visceral adipose tissue (VAT). Mechanistically, nobiletin significantly inhibited Akt and Erk activation in placenta, and NF-κB activation in VAT. In vivo, GDM mice treated with 50 mg/kg nobiletin daily via oral gavage from gestational day (gd) 1-17 or via i.p. injections from gd 10-17 significantly improved glucose tolerance. Pregnant GDM mice treated with nobiletin from either gd 1-17 or gd 10-17 exhibited significantly suppressed mRNA expression of pro-inflammatory cytokines and chemokines in placenta, VAT and subcutaneous adipose tissue (SAT). Using a quantitative mass spectrometry approach, we identified differentially abundant proteins associated with the effect of nobiletin in vivo. Together, these studies demonstrate that nobiletin improves glucose metabolism and reduces inflammation associated with GDM and may be a novel therapeutic for the prevention of GDM.

BACKGROUND: Strong associations between diet and maternal and child outcomes emphasise the importance of evidence-based care for women across preconception, antenatal and postnatal periods. A 2008 survey of Australian maternal health dietetic services documented critically low resourcing with considerable variation in staffing levels and models of care. This study repeated the survey to examine resourcing in Australian maternal health services. METHODS: A cross-sectional online survey was emailed to publicly-funded Australian maternal health dietetic services in May 2018. Quantitative and qualitative variables collected across preconception to postnatal services (including diabetes) included; births per year (BPY), number of beds, staffing (full time equivalents; FTE), referral processes, and models of care. Results were collated in > 5000; 3500 and 5000; and < 3500 BPY. RESULTS: Forty-three eligible surveys were received from seven states/territories. Dietetic staffing levels ranged from 0 to 4.0 FTE (> 5000 BPY), 0-2.8 FTE (3500-5000 BPY), and 0-2.0 FTE (< 3500 BPY). The offering of preconception, antenatal and postnatal services varied significantly between hospitals (format, staffing, referral processes, delivery models). Few sites reported service effectiveness monitoring and only one delivered gestational diabetes mellitus care according to nutrition practice guidelines. Low staffing levels and extensive service gaps, including lack of processes to deliver and evaluate services, were evident with major concerns expressed about the lack of capacity to provide evidence-based care. CONCLUSIONS: Ten years after the initial survey and recommendations there remains an identified role for dietitians to advocate for better staffing and for development, implementation, and evaluation of service models to influence maternal nutrition.

BACKGROUND: Early excess and inadequate gestational weight gain (GWG) have been associated with negative outcomes for mother and child. The use of digital media to deliver pregnancy lifestyle interventions is increasing, but there is little data on participant engagement. The Pregnancy Lifestyle Activity and Nutrition (PLAN) intervention pilot study was an electronic health and dietetic-delivered intervention program promoting healthy GWG in early pregnancy. OBJECTIVE: This study aims to explore the interactions of participants with the program and to assess its acceptability. METHODS: This study uses both quantitative and qualitative methods using data from parent randomized controlled trial (ACTRN12617000725369). Quantitative data from 22 participants in the intervention arm who completed the study provided measures of the interactions participants had with the digital components of the program and with dietetic consultations. A descriptive qualitative analysis employed semistructured interviews with 9 participants to elicit views on the acceptability of the intervention and its components. RESULTS: The electronic delivery of information and recording of weight from 8 to 20 weeks of gestation were universally accepted. Component (face-to-face dietitian, weight tracker, website information delivery, and SMS goal prompting) acceptability and engagement differed between individuals. A total of 4 key themes emerged from the qualitative analysis: supporting lifestyle change, component acceptability and value, delivery platforms, and engagement barriers. CONCLUSIONS: The PLAN intervention and its delivery via a blend of personal dietetic consultations and digital program delivery was found to be acceptable and valuable to pregnant women. Individuals responded differently to various components, emphasizing the importance of including women in the development of lifestyle interventions and allowing participants to choose and tailor programs. Larger randomized controlled trials using these insights in a broader section of the community are needed to inform the iterative development of practical, time-efficient, and cost-effective ways of supporting optimal GWG with the potential to optimize outcomes for pregnant women and their child.

In the quest to discover the next high-technology solution to solve many health problems, proven established technologies are often overlooked in favor of more "technologically advanced" systems that have not been fully explored for their applicability to support behavior change theory, or used by consumers. Text messages or SMS is one example of an established technology still used by consumers, but often overlooked as part of the mobile health (mHealth) toolbox. The purpose of this paper is to describe the benefits of text messages as a health promotion modality and to advocate for broader scale implementation of efficacious text message programs. Text messaging reaches consumers in a ubiquitous real-time exchange, contrasting the multistep active engagement required for apps and wearables. It continues to be the most widely adopted and least expensive mobile phone function. As an intervention modality, text messaging has taught researchers substantial lessons about tailored interactive health communication; reach and engagement, particularly in low-resource settings; and embedding of behavior change models into digital health. It supports behavior change techniques such as reinforcement, prompts and cues, goal setting, feedback on performance, support, and progress review. Consumers have provided feedback to indicate that text messages can provide them with useful information, increase perceived support, enhance motivation for healthy behavior change, and provide prompts to engage in health behaviors. Significant evidence supports the effectiveness of text messages alone as part of an mHealth toolbox or in combination with health services, to support healthy behavior change. Systematic reviews have consistently reported positive effects of text message interventions for health behavior change and disease management including smoking cessation, medication adherence, and self-management of long-term conditions and health, including diabetes and weight loss. However, few text message interventions are implemented on a large scale. There is still much to be learned from investing in text messaging delivered research. When a modality is known to be effective, we should be learning from large-scale implementation. Many other technologies currently suffer from poor long-term engagement, the digital divide within society, and low health and technology literacy of users. Investing in and incorporating the learnings and lessons from large-scale text message interventions will strengthen our way forward in the quest for the ultimate digitally delivered behavior change model.

BACKGROUND: Promoting healthy gestational weight gain (GWG) is important for preventing obstetric and perinatal morbidity, along with obesity in both mother and child. Provision of GWG guidelines by health professionals predicts women meeting GWG guidelines. Research concerning women's GWG information sources is limited. This study assessed pregnant women's sources of GWG information and how, where and which women seek GWG information. METHODS: Consecutive women (n = 1032) received a mailed questionnaire after their first antenatal visit to a public maternity hospital in Melbourne, Australia. Recalled provision of GWG guidelines by doctors and midwives, recalled provided GWG goals, and the obtaining of GWG information and information sources were assessed. RESULTS: Participants (n = 368; 35.7% response) averaged 32.5 years of age and 20.8 weeks gestation, with 33.7% speaking a language other than English. One in ten women recalled receiving GWG guidelines from doctors or midwives, of which half were consistent with Institute of Medicine guidelines. More than half the women (55.4%) had actively sought GWG information. Nulliparous (OR 7.07, 95% CI = 3.91-12.81) and obese (OR 1.96, 95% CI = 1.05-3.65) women were more likely to seek information. Underweight (OR 0.29, 95% CI = 0.09-0.97) women and those working part time (OR 0.52, 95% CI = 0.28-0.97) were less likely to seek information. Most frequently reported GWG sources included the internet (82.7%), books (55.4%) and friends (51.5%). The single most important sources were identified as the internet (32.8%), general practitioners (16.9%) and books (14.9%). CONCLUSION: More than half of women were seeking GWG guidance and were more likely to consult non-clinician sources. The small numbers given GWG targets, and the dominance of non-clinical information sources, reinforces that an important opportunity to provide evidence based advice and guidance in the antenatal care setting is currently being missed.

AIMS: In 2019, the Australian Academy of Science in collaboration with the nutrition community published the decadal plan for the science of nutrition. This article aims to review progress towards each of its pillar goals (societal determinants, nutrition mechanisms, precision and personalised nutrition, and education and training) and two enabling platforms (a national data capability and a trusted voice for nutrition science), prioritise actions, and conceptualise program logic implementation models. This process also brought together public health nutrition researchers to reflect on societal determinants of health, and advise how the next 5 years of the decadal plan could reflect contemporary issues. METHODS: Two engagement events, in 2023, brought together experienced and mid- and early-career nutrition professionals for co-creation of implementation logic models. RESULTS: One hundred and nine early and mid-career professionals were involved. A revised model for the decadal plan pillars emerged from synthesis of all logic models. This new model integrated the precision and personalised nutrition pillar with nutrition mechanisms pillar. These combined pillars build towards the national data capability enabling platform and created new cross-cutting themes for education and training. The need arose for greater focus on respectful engagement with Aboriginal and Torres Strait Islander communities and sustained effort to build cross-disciplinary collaboration to realise the plan's societal determinants goals. A new alliance for nutrition science is proposed to become a unified advocacy voice and build trust in nutrition professionals. CONCLUSIONS: A programmatic approach provides a road map for implementing the decadal plan for the final 5 years.

BACKGROUND: Postnatal depression (PND) is a leading cause of illness and death among women following childbirth. Physical inactivity, sedentary behaviour, poor sleep, and sub-optimal diet quality are behavioural risk factors for PND. A feasible, sustainable, and scalable intervention to improve healthy behaviours and reduce PND symptoms among women at postpartum is needed. This study aims to examine the effectiveness of a multi-behavioural home-based program Food, Move, Sleep (FOMOS) for Postnatal Mental Health designed to improve PND symptoms in women at postpartum. METHODS: This randomised clinical trial will recruit 220 Australian women (2-12 months postpartum) experiencing heightened PND symptoms (Edinburgh Postnatal Depression Scale score ≥ 10). Participants will be randomised to FOMOS or wait-list control receiving standard clinical care. FOMOS is a 6-month mobile health (mHealth) intervention targeting diet quality, physical activity, sedentary behaviour, sleep, and mental health. The intervention, informed by the Social Cognitive Theory and incorporating behaviour change techniques defined in the CALO-RE taxonomy and Cognitive Behavioural Treatment of Insomnia, provides exercise equipment, and educational/motivational material and social support via mHealth and social media. Data collection pre-intervention and at 3, 6 and 12 months will assess the primary outcome of PND symptoms and secondary outcomes (diet quality, physical activity, sitting time, sleep quality) using self-report and device measures. Process evaluation will explore acceptability, appropriateness, cost-effectiveness, feasibility, and sustainability via analytic tools, record keeping, interviews, and surveys. DISCUSSION: If effective, FOMOS could be a feasible and potentially scalable management strategy to support improvement of health behaviours and mental health for women with PND symptoms.

txt4two is a multi-modality intervention promoting healthy pregnancy nutrition, physical activity (PA), and gestational weight gain (GWG), which had been previously evaluated in a pilot randomized controlled trial (RCT). This study aimed to evaluate a pragmatic implementation of an adapted version of txt4two in a public tertiary hospital. Using a consecutive cohort design, txt4two was delivered to women with a pre-pregnancy BMI > 25 kg/m2, between 10 + 0 to 17 + 6 weeks. Control and intervention cohorts (n = 150) were planned, with surveys and weight measures at baseline and 36 weeks. The txt4two cohort received a dietetic goal-setting appointment and program (SMS, website, and videos). The navigation of disparate hospital systems and the COVID-19 pandemic saw adaptation and adoption take two years. The intervention cohort (n = 35; 43% full data) demonstrated significant differences (mean (SD)), compared to the control cohort (n = 97; 45% full data) in vegetable intake (+0.9 (1.2) versus +0.1 (0.7), p = 0.03), fiber-diet quality index (+0.6 (0.8) versus 0.1 (0.5), p = 0.012), and total diet quality index (+0.7 (1.1) versus +0.2 (±0.6), p = 0.008), but not for PA or GWG. Most (85.7%) intervention participants found txt4two extremely or moderately useful, and 92.9% would recommend it. Embedding the program in a non-RCT context raised implementation challenges. Understanding the facilitators and barriers to adaptation and adoption will strengthen the evidence for the refinement of implementation plans.

AIM: Optimising preconception health increases the likelihood of conception, positively influences short- and long-term pregnancy outcomes and reduces intergenerational chronic disease risk. Our aim was to synthesise study characteristics and maternal outcomes of digital or blended (combining face to face and digital modalities) interventions in the preconception period. METHODS: We searched six databases (PubMed, Cochrane, Embase, Web of Science, CINHAL and PsycINFO) from 1990 to November 2022 according to the PRISMA guidelines for randomised control trials, quasi-experimental trials, observation studies with historical control group. Studies were included if they targeted women of childbearing age, older than 18 years, who were not currently pregnant and were between pregnancies or/and actively trying to conceive. Interventions had to be delivered digitally or via digital health in combination with face-to-face delivery and aimed to improve modifiable behaviours, including dietary intake, physical activity, weight and supplementation. Studies that included women diagnosed with type 1 or 2 diabetes were excluded. Risk of bias was assessed using the Academy of Nutrition and Dietetics quality criteria checklist. Study characteristics, intervention characteristics and outcome data were extracted. RESULTS: Ten studies (total participants n=4,461) were included, consisting of nine randomised control trials and one pre-post cohort study. Seven studies received a low risk of bias and two received a neutral risk of bias. Four were digitally delivered and six were delivered using blended modalities. A wide range of digital delivery modalities were employed, with the most common being email and text messaging. Other digital delivery methods included web-based educational materials, social media, phone applications, online forums and online conversational agents. Studies with longer engagement that utilised blended delivery showed greater weight loss. CONCLUSION: More effective interventions appear to combine both traditional and digital delivery methods. More research is needed to adequately test effective delivery modalities across a diverse range of digital delivery methods, as high heterogeneity was observed across the small number of included studies.
RESUMO
Living Well during Pregnancy (LWdP) is a telephone-based antenatal health behavior intervention that has been shown to improve healthy eating behaviors and physical activity levels during pregnancy. However, one-third of eligible, referred women did not engage with or dropped out of the service. This study aimed to explore the experiences and perceptions of women who were referred but did not attend or complete the LWdP program to inform service improvements and adaptations required for scale and spread and improve the delivery of patient-centered antenatal care. Semi-structured telephone interviews were conducted with women who attended ≤2 LWdP appointments after referral. The interviews were thematically analyzed and mapped to the Theoretical Domains Framework and Behavior Change Wheel/COM-B Model to identify the barriers and enablers of program attendance and determine evidence-based interventions needed to improve service engagement and patient-centered antenatal care. Three key themes were identified: (1) the program content not meeting women's expectations and goals; (2) the need for flexible, multimodal healthcare; and (3) information sharing throughout antenatal care not meeting women's information needs. Interventions to improve women's engagement with LWdP and patient-centered antenatal care were categorized as (1) adaptations to LWdP, (2) training and support for program dietitians and antenatal healthcare professionals, and (3) increased promotion of positive health behaviors during pregnancy. Women require flexible and personalized delivery of the LWdP that is aligned with their individual goals and expectations. The use of digital technology has the potential to provide flexible, on-demand access to and engagement with the LWdP program, healthcare professionals, and reliable health information. All healthcare professionals are vital to the promotion of positive health behaviors in pregnancy, with the ongoing training and support necessary to maintain clinician confidence and knowledge of healthy eating, physical activity, and weight gain during pregnancy.

BACKGROUND: Excess gestational weight gain (GWG) can affect the immediate and long term health outcomes of mother and infant. Understanding health providers' views, attitudes and practices around GWG is crucial to assist in the development of practical, time efficient and cost effective ways of supporting health providers to promote healthy GWGs. This study aimed to explore midwives' views, attitudes and approaches to the assessment, management and promotion of healthy GWG and to investigate their views on optimal interventions. METHODS: Midwives working in antenatal care were recruited from one rural and one urban Australian maternity hospital employing purposive sampling strategies to assess a range of practice areas. Face-to-face interviews were conducted with 15 experienced midwives using an interview guide and all interviews were digitally recorded, transcribed verbatim and analysed thematically. RESULTS: Midwives interviewed exhibited a range of views, attitudes and practices related to GWG. Three dominant themes emerged. Overall GWG was given low priority for midwives working in the antenatal care service in both hospitals. In addition, the midwives were deeply concerned for the physical and psychological health of pregnant women and worried about perceived negative impacts of discussion about weight and related interventions with women. Finally, the midwives saw themselves as central in providing lifestyle behaviour education to pregnant women and identified opportunities for support to promote healthy GWG. CONCLUSIONS: The findings indicate that planning and implementation of healthy GWG interventions are likely to be challenging because the factors impacting on midwives' engagement in the GWG arena are varied and complex. This study provides insights for guideline and intervention development for the promotion of healthy GWG.

BACKGROUND: The impact of excess gestational weight gain (GWG) on maternal and child health outcomes is well documented. Understanding how health care providers view and manage GWG may assist with influencing healthy gestational weight outcomes. This study aimed to assess General Practitioner's (GPs) perspectives regarding the management and assessment of GWG and to understand how GPs can be best supported to provide healthy GWG advice to pregnant women. METHODS: Descriptive qualitative research methods utilising semi - structured interview questions to assess GPs perspectives and management of GWG. GPs participating in shared antenatal care in Geelong, Victoria and Sydney, New South Wales were invited to participate in semi - structured, individual interviews via telephone or in person. Interviews were digitally recorded and transcribed verbatim. Data was analysed utilising thematic analysis for common emerging themes. RESULTS: Twenty eight GPs participated, 14 from each state. Common themes emerged relating to awareness of the implications of excess GWG, advice regarding weight gain, regularity of gestational weighing by GPs, options for GPs to seek support to provide healthy lifestyle behaviour advice and barriers to engaging pregnant women about their weight. GPs perspectives concerning excess GWG were varied. They frequently acknowledged maternal and child health complications resulting from excess GWG yet weighing practices and GWG advice appeared to be inconsistent. The preferred support option to promote healthy weight was referral to allied health practitioners yet GPs noted that cost and limited access were barriers to achieving this. CONCLUSIONS: GPs were aware of the importance of healthy GWG yet routine weighing was not standard practice for diverse reasons. Management of GWG and perspectives of the issue varied widely. Time efficient and cost effective interventions may assist GPs in ensuring women are supported in achieving healthy GWG to provide optimal maternal and infant health outcomes.

OBJECTIVE: To investigate Indonesian pregnant women's experiences in seeking and receiving nutrition information. DESIGN: Qualitative semi-structured interviews analysed with thematic analysis. SETTING AND PARTICIPANTS: Twenty-three pregnant women in Malang City, Indonesia were interviewed between December 2018 and January 2019. FINDINGS: Four key themes emerged concerning pregnant women's nutrition information-seeking behaviour: (i) Most women passively received nutrition information rather than actively seeking it; (ii) Women sought and received nutrition information from multiple sources including health professionals, social networks and the Internet, with varying levels of trust; (iii) Health professionals, including doctors, midwives and nutritionists, did not provide consistent and timely information; and (iv) Most women could identify gaps between nutrition information provided by health professionals and their expectations. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: This study identified opportunities for Indonesian health authorities to enhance their nutrition education services. This study suggests improvements that could extend the systematic provision of nutrition education to meet the needs of pregnant women in developing countries.
