Cultural food practices and sources of nutrition information among pregnant and postpartum migrant women from low- and middle-income countries residing in high income countries: A systematic review.

Women in low- and middle-income countries (LMICs) may engage in a range of cultural food practices during pregnancy, including restricting or avoiding foods high in protein and iron, and foods rich in vitamins and minerals. While research has explored the cultural food practices of pregnant women in LMICs, there is less understanding of the continued cultural food practices of women who migrate to high-income countries and then become pregnant. This systematic review explores the existing research on cultural food practices and sources of nutrition information among pregnant and postpartum migrant women from LMICs, residing in high-income countries. A systematic search was conducted in April 2024 across Global Health, CINAHL, and MEDLINE, published in English, with no date restrictions. Eligible studies included those focused on pregnant and postpartum women who had migrated from LMICs to high-income countries. Studies were excluded if they comprised of non-immigrant women or did not involve LMIC participants. Screened were studies for eligibility, data were extracted, and study quality was assessed. In total, 17 studies comprising qualitative (n = 10) and quantitative (n = 7) approaches were included. In 14 studies participants adhered to cultural food practices, wherein certain nutritious foods were restricted during pregnancy or the postpartum period; three studies noted limited adherence due to support, acculturation, and access to traditional foods. Most studies (n = 10) reported traditional "hot" and "cold" food beliefs during pregnancy and postpartum, aiming to maintain humoral balance for maternal and child health and to prevent miscarriage. Nutrition advice was sought from family members, friends, relatives, healthcare providers, and media sources, with a preference for advice from family members in their home countries. There is a need for culturally appropriate nutrition education resources to guide pregnant migrants through healthy and harmful cultural food practices and overall nutrition during this crucial period.

Associations between diet quality and dietary patterns and gestational diabetes mellitus in a low-risk cohort of pregnant women in Australia: a cross-sectional study.

INTRODUCTION: Evidence of associations between the Mediterranean Diet Score (MDS) and Dietary Approaches to Stop Hypertension (DASH) score and gestational diabetes mellitus (GDM) in pregnant women is limited. This study examined changes in MDS and DASH and dietary patterns in Australian pregnant women between early and late pregnancy and their associations with GDM. METHODS: The data from n = 284 participants were analysed. Diet quality indices and empirical dietary patterns were determined in early (15 ± 3 weeks gestation) and late pregnancy (35 ± 2 weeks gestation). Paired t-tests were used to examine changes in scores for diet quality indices and dietary patterns from early to late pregnancy. Logistic regression analysis was used to examine associations between GDM, diet quality indices and dietary patterns. RESULTS: Three major dietary patterns were identified at early pregnancy. The first and second dietary patterns included unhealthier and healthier food groups, respectively, and the third comprised mixed food groups. Although diet quality scores did not change over time, consumption of the first dietary pattern increased (p = 0.01), and consumption of the second dietary pattern decreased by late pregnancy in women without GDM (p < 0.001). CONCLUSION: No associations between DASH score, MDS and GDM were found; however an inverse association was observed between the first dietary pattern and GDM in late pregnancy (p = 0.023). Longitudinal studies are needed to examine diet quality and dietary patterns at early and late pregnancy to inform the development of tailored dietary advice for GDM.

Associations of adherence to the DASH diet and Mediterranean diet with maternal c-reactive protein levels during pregnancy.

BACKGROUND AND AIMS: Elevated C-reactive protein (CRP) during pregnancy, a marker of inflammation, is associated with adverse outcomes. Better understanding the relationship between CRP and modifiable factors, including diet, is essential to assist early pregnancy lifestyle interventions. The aim of this study was to assess the relationship between adherence to the Dietary Approaches to Stop Hypertension diet (DASH-diet) and the Mediterranean diet (MED-diet) during pregnancy with maternal plasma CRP in early and late pregnancy. METHODS AND RESULTS: Secondary analysis of the Creatine and Pregnancy Outcomes (CPO) study was undertaken. Women (n = 215) attending antenatal clinics through Monash Health, Melbourne were recruited at 10-20 weeks gestation. Medical history and blood samples were collected at 5 antenatal visits. Adapted DASH-diet and MED-diet scores were calculated from Food Frequency Questionnaires completed at early ([mean ± SD]) (15 ± 3 weeks) and late (36 ± 1 week) pregnancy. CRP was measured in maternal plasma samples collected at the same time points. Adjusted linear regression models assessed associations of early-pregnancy DASH and MED-diet scores with early and late pregnancy plasma CRP. There were no statistically significant changes in DASH-diet score from early (23.5 ± 4.8) to late (23.5 ± 5.2) pregnancy (p = 0.97) or MED-diet score from early (3.99 ± 1.6) to late pregnancy (4.08 ± 1.8) (p = 0.41). At early-pregnancy, there was an inverse relationship between DASH-diet scores and MED-diet scores with plasma CRP; (ß = -0.04 [95%CI = -0.07, -0.00], p = 0.044), (ß = -0.12 [95%CI = -0.21, -0.02], p = 0.023). CONCLUSION: Adherence to the DASH-diet and MED-diet during early pregnancy may be beneficial in reducing inflammation. Assessment of maternal dietary patterns may assist development of preventive strategies, including dietary modification, to optimise maternal cardiometabolic health in pregnancy.

Cross-cultural food practices and nutrition seeking behaviors among pregnant and postpartum Indian women living in Australia.

No research has explored the experiences of Indian women who become pregnant after they migrate to Australia, and how their existing traditions mix with their new environment and subsequently impact eating patterns. Semi-structured interviews were conducted with eleven women of Indian heritage who were living in Australia, and data were thematically analyzed. The researchers identified two main themes were identified (a) foods to eat and which to avoid, and (b) support networks and sources of health information during pregnancy. Women get advice and information from a range of sources and have diverse attitudes and beliefs about cultural food practices. that are both rigid and flexible, as well as traditional and contemporary.

Antenatal healthcare providers' knowledge, attitudes and practices regarding food insecurity in pregnancy: A qualitative investigation based at a specialist antenatal hospital in Melbourne, Australia.

BACKGROUND: Food insecurity exists when accessibility and availability of nutritious food is restricted, increasing the risk of adverse health outcomes. Pregnant women are especially vulnerable to food insecurity, which is concerning as optimal nutrition to support both their own health and the health and growth of their unborn child is critical. Antenatal healthcare providers (AHPs) are central to provision of pregnancy care. We aimed to assess AHPs' knowledge, attitudes and management of food insecurity. METHODS: Semi-structured interviews were conducted face-to-face, via telephone or online via Webex with 16 AHPs at the Royal Women's Hospital located in Melbourne, Australia. Interviews were thematically analysed according to Charmaz's constructivist grounded theory approach to ascertain AHPs' knowledge, attitudes and practices regarding food insecurity during pregnancy. RESULTS: AHPs had limited knowledge and awareness of food insecurity in pregnancy. Lack of experience in managing food insecurity and time constraints limit their capacity to support and deliver care to food-insecure women. There was a reported lack of structure and clarity surrounding referral pathways for effective management of food insecurity during pregnancy, as well as a lack of clarity regarding practitioner responsibility in managing this issue. CONCLUSIONS: Current assessment and management of food insecurity during pregnancy in the antenatal setting is suboptimal. Professional development strategies targeted to AHPs are urgently needed to assist optimal care of women who are food insecure during pregnancy to assist with supporting best maternal and child health.

Evaluating a multi-behavioural home-based intervention for reducing depressive symptoms in postnatal women : The food, move, sleep (FOMOS) for postnatal mental health randomised controlled trial protocol.

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.

BMC pregnancy and childbirth - 'screening and management of food insecurity in pregnancy'.

Addressing food insecurity during pregnancy is a major public health problem that demands guided interventions and translational research in public health. In this Editorial, we provide the context and invite contributions for our BMC Pregnancy and Childbirth Collection on Screening and management of food insecurity in pregnancy.

Could commercial meal kits be part of the solution to food insecurity during pregnancy? An Australian exploratory study.

AIM: To explore the nutritional content of meal kits from two main Australian companies over a 6-week period against healthy eating guidelines for pregnancy. METHOD: Across the 6-week period, weekly meal kits from both Provider 1 and Provider 2 were purchased, 36 individual meals were assessed. All data were analysed for the development of a macronutrient and micronutrient profile of meals. Extracted data were macronutrient, vitamin, and mineral composition, which were compared against the healthy eating guidelines for pregnant women in Australia and New Zealand. RESULTS: Meal kits include higher levels of sodium, and lower levels of dietary fibre, calcium, magnesium, zinc, iron, thiamin, riboflavin, grains, and dairy when compared against the guidelines for healthy eating for pregnant women in Australia and New Zealand. CONCLUSIONS AND IMPLICATIONS: Meal kits may increase meals prepared and consumed in the home, and thanks to the clear instructions and pre-portioned ingredients, may reduce stress related to food preparation. They have the potential to provide nutritionally adequate meals to pregnant women as a way to mitigate food insecurity or hunger during pregnancy and may provide some nutritional benefits and have the potential to remove some of the challenges with maintaining an adequate diet when pregnant.

Associations of a current Australian model of dietetic care for women diagnosed with gestational diabetes and maternal and neonatal health outcomes.

BACKGROUND: Gestational diabetes mellitus (GDM) is a significant public health burden in Australia. Subsequent strain on healthcare systems is widespread and current models of care may not be adequate to provide optimal healthcare delivery. This study aimed to assess a current model of dietetic care with maternal and neonatal outcomes. METHODS: Hospital medical record data from The Women's Hospital, Melbourne, for women with GDM (n = 1,185) (July 2105-May 2017) was retrospectively analysed. Adjusted linear and logistic regression were used to analyse associations between the number of dietitian consultations and maternal and neonatal health outcomes. RESULTS: Half of all women (50%) received two consultations with a dietitian. 19% of women received three or more consultations and of these women, almost twice as many were managed by medical nutrition therapy (MNT) and pharmacotherapy (66%) compared with MNT alone (34%). Higher odds of any maternal complication among women receiving 3 + consultations compared to those receiving zero (OR = 2.33 [95% CI: 1.23, 4.41], p = 0.009), one (OR = 1.80 [95% CI: 1.09, 2.98], p = 0.02), or two (OR = 1.65 [95% CI: 1.04, 2.60], p = 0.03) consultations were observed. Lower odds of infant admission to the Neonatal Intensive Care Unit (NICU) were observed among women receiving one (OR = 0.38 [95% CI: 0.18, 0.78], p = 0.008), two (OR = 0.37 [95% CI: 15 0.19, 0.71], p = 0.003), or three + consultations (OR = 0.43 [95% CI: 0.21, 0.88], p = 0.02), compared to no consultations. CONCLUSION: The optimal schedule of dietitian consultations for women with GDM in Australia remains largely unclear. Alternate delivery of education for women with GDM such as telehealth and utilisation of digital platforms may assist relieving pressures on the healthcare system and ensure optimal care for women during pregnancy.

Maternal diet quality and associations with plasma lipid profiles and pregnancy-related cardiometabolic health.

PURPOSE: To assess the relationship of early pregnancy maternal diet quality (DQ) with maternal plasma lipids and indicators of cardiometabolic health, including blood pressure (BP), gestational diabetes mellitus (GDM) and gestational weight gain (GWG). METHODS: Women (n = 215) aged 18-40 years with singleton pregnancies were recruited at 10-20 weeks gestation. Diet quality was assessed by the Dietary Guideline Index, calculated at early ([mean ± SD]) (15 ± 3 weeks) and late (35 ± 2 weeks) pregnancy. Lipidomic analysis was performed, and 698 species across 37 lipid classes were measured from plasma blood samples collected at early (15 ± 3 weeks) and mid (27 ± 3 weeks)-pregnancy. Clinical measures (BP, GDM diagnosis, weight) and blood samples were collected across pregnancy. Multiple linear and logistic regression models assessed associations of early pregnancy DQ with plasma lipids at early and mid-pregnancy, BP at three antenatal visits, GDM diagnosis and total GWG. RESULTS: Maternal DQ scores ([mean ± SD]) decreased significantly from early (70.7 ± 11.4) to late pregnancy (66.5 ± 12.6) (p < 0.0005). At a false discovery rate of 0.2, early pregnancy DQ was significantly associated with 13 plasma lipids at mid-pregnancy, including negative associations with six triglycerides (TGs); TG(54:0)[NL-18:0] (neutral loss), TG(50:1)[NL-14:0], TG(48:0)[NL-18:0], TG(52:1)[NL-18:0], TG(54:1)[NL-18:1], TG(50:0)[NL-18:0]. No statistically significant associations were found between early pregnancy DQ and BP, GDM or GWG. CONCLUSION: Maternal diet did not adhere to Australian Dietary Guidelines. Diet quality was inversely associated with multiple plasma TGs. This study provides novel insights into the relationship between DQ, lipid biomarkers and cardiometabolic health during pregnancy.

Measuring Food Insecurity in India: A Systematic Review of the Current Evidence.

PURPOSE OF REVIEW: India is home to an estimated 200 million malnourished people, suggesting widespread food insecurity. However, variations in the methods used for determining food insecurity status mean there is uncertainty in the data and severity of food insecurity across the country. This systematic review investigated the peer-reviewed literature examining food insecurity in India to identify both the breadth of research being conducted as well as the instruments used and the populations under study. RECENT FINDINGS: Nine databases were searched in March 2020. After excluding articles that did not meet the inclusion criteria, 53 articles were reviewed. The most common tool for measuring food insecurity was the Household Food Insecurity Access Scale (HFIAS), followed by the Household Food Security Survey Module (HFSSM), and the Food Insecurity Experience Scale (FIES). Reported food insecurity ranged from 8.7 to 99% depending on the measurement tool and population under investigation. This study found variations in methods for the assessment of food insecurity in India and the reliance on cross-sectional studies. Based on the findings of this review and the size and diversity of the Indian population, there is an opportunity for the development and implementation of an Indian-specific food security measure to allow researchers to collect better data on food insecurity. Considering India's widespread malnutrition and high prevalence of food insecurity, the development of such a tool will go part of way in addressing nutrition-related public health in India.

Food insecurity screening procedures used in reproductive healthcare settings.

CONTEXT: Food insecurity is an important determinant of health and should be identified by clinicians during routine reproductive healthcare. The procedures used in reproductive healthcare settings to identify people experiencing food insecurity have not been fully researched. OBJECTIVE: The objective of this study was to synthesize evidence from published studies that describe the procedures implemented by clinicians in healthcare settings to identify food insecurity in pregnant women, or women of reproductive age (15 years-49 years). DATA SOURCES: Four databases were searched in April 2022 to identify studies that met the eligibility criteria. DATA EXTRACTION: Studies that used tools that were both validated or newly developed were considered, as were studies that incorporated food insecurity screening as part of a multidomain screening tool. Two authors completed the screening, data extraction, and quality assessment independently. DATA ANALYSIS: There were 1075 studies identified; after screening, 7 studies were included in the narrative synthesis, including studies relating to women who were pregnant or in the postpartum period; none of the included studies related to women in the preconception stage. Four screening tools were identified: 2- and 6-item tools specifically focused on food insecurity, a 58-item multidomain tool incorporating 4 food insecurity items, and a modified version of the 2-item tool. Methods of implementing screening varied across studies. Three described subsequent processes that supported food-insecure patients once identified. CONCLUSION: Few published studies have investigated optimal screening tools and their implementation within reproductive healthcare settings to address food insecurity for this priority population group. Further research is required to determine: the optimal tool, preferable screening methods from the perspectives of both patients and clinicians, and potential strategies for implementation in countries outside of the United States. An additional evidence gap remains about referral pathways and appropriate supports for this population once food insecurity is identified. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no.

Maternal plasma vitamin D levels across pregnancy are not associated with neonatal birthweight: findings from an Australian cohort study of low-risk pregnant women.

BACKGROUND: In utero environments can be highly influential in contributing to the development of offspring obesity. Specifically, vitamin D deficiency during pregnancy is associated with adverse maternal and child health outcomes, however its relationship with offspring obesity remains unclear. We assessed maternal vitamin D status across pregnancy, change in plasma vitamin D concentrations and associations with neonatal birthweight, macrosomia and large for gestational age. METHODS: Women (n = 221) aged 18-40 years with singleton (low-risk) pregnancies, attending antenatal clinics at a tertiary-level maternity hospital were recruited at 10-20 weeks gestation. Medical history, maternal weight and blood samples at three antenatal clinic visits were assessed; early (15 ± 3 weeks), mid (27 ± 2 weeks) and late (36 ± 1 weeks) gestation. Maternal 25(OH)D was analysed from stored plasma samples via liquid chromatography-tandem mass spectrometry (LC/MS/MS). Neonatal growth parameters were collected at birth. Unadjusted and adjusted linear and logistic regression assessed associations of maternal vitamin D with birthweight, macrosomia and large for gestational age. RESULTS: Mean plasma 25(OH)D increased from early (83.8 ± 22.6 nmol/L) to mid (96.5 ± 28.9 nmol/L) and late (100.8 ± 30.8 nmol/L) gestation. Overall 98% of women were taking vitamin D-containing supplements throughout their pregnancy. Prevalence of vitamin D deficiency (25(OH)D < 50 nmol/L) was 6.5%, 6.3% and 6.8% at early, mid and late pregnancy respectively. No statistically significant association was found between 25(OH)D or vitamin D deficiency at any timepoint with neonatal birthweight, macrosomia or large for gestational age. CONCLUSIONS: Prevalence of vitamin D deficiency was low in this cohort of pregnant women and likely related to the high proportion of women taking vitamin D supplements during pregnancy. Maternal 25(OH)D did not impact offspring birth weight or birth size. Future studies in high-risk pregnant populations are needed to further assess maternal vitamin D status and factors in utero which promote early life obesity.

Vitamin C supplementation for diabetes management: A comprehensive narrative review.

Growing evidence suggests that vitamin C supplementation may be an effective adjunct therapy in the management of people with diabetes. This paper critically reviews the current evidence on effects of vitamin C supplementation and its potential mechanisms in diabetes management. Evidence from meta-analyses of randomized controlled trials (RCTs) show favourable effects of vitamin C on glycaemic control and blood pressure that may be clinically meaningful, and mixed effects on blood lipids and endothelial function. However, evidence is mostly of low evidence certainty. Emerging evidence is promising for effects of vitamin C supplementation on some diabetes complications, particularly diabetic foot ulcers. However, there is a notable lack of robust and well-designed studies exploring effects of vitamin C as a single compound supplement on diabetes prevention and patient-important outcomes (i.e. prevention and amelioration of diabetes complications). RCTs are also required to investigate potential preventative or ameliorative effects of vitamin C on gestational diabetes outcomes. Oral vitamin C doses of 500-1000 mg per day are potentially effective, safe, and affordable for many individuals with diabetes. However, personalisation of supplementation regimens that consider factors such as vitamin C status, disease status, current glycaemic control, vitamin C intake, redox status, and genotype is important to optimize vitamin C's therapeutic effects safely. Finally, given a high prevalence of vitamin C deficiency in patients with complications, it is recommended that plasma vitamin C concentration be measured and monitored in the clinic setting.

Screening Food Insecure during Pregnancy: Pilot Testing an Effective Brief Tool for Use in an Australian Antenatal Care Setting.

The purpose of this research is: (1) to determine the prevalence of food insecurity among pregnant people using the 10-, 6-, and 2-item iterations of the USA Household Food Security Survey Module (HFSSM) and the single item measure, and (2) identify an appropriate combination of questions that could be used to identify food insecurity in a clinical setting for a population of people who are pregnant in Australia. Cross-sectional survey collecting self-reported data from pregnant people in Australia (open May 2021 to March 2022). Survey included demographic characteristics, including income/welfare use, education, age, pregnancy information, household size and composition, and two measures of food insecurity. In total, 303 participants were included in the analysis. Sensitivity and specificity of the various combinations of questions were conducted. Food insecurity was estimated using the single item, and the 2-item, 6-item, and 10-item versions of the HFSSM, food insecurity was 6.2%, 11.4%, 11.7%, and 14.3% respectively. Respondents who were living in households that were food insecure answered affirmatively to question one, two, or three of the HFSSM, with the combination of questions one and three showing the best sensitivity and specificity for the whole sample, as well as for those who have characteristics likely to lead to food insecurity. Further testing of the 2-items, comprised of items one and three from the HFSSM, need to be conducted with a larger and more diverse sample to determine if this is an appropriate screening tool in an antenatal clinical setting to determine food insecurity during pregnancy.

Consensus from an expert panel on how to identify and support food insecurity during pregnancy: A modified Delphi study.

BACKGROUND: Food insecurity and hunger during pregnancy have significant implications for the health of the mother and baby. Assisting clinicians when they encounter women who are experiencing hunger or food insecurity during their pregnancy will increase the opportunity for better birth and pregnancy outcomes. At present there are no guidelines for Australian clinicians on how to do this. METHODS: This study uses a modified Delphi technique, allowing diverse participation in the process, to create consensus on the ways to address and respond to food insecurity during pregnancy. This modified Delphi collected data via two rounds of consensus. The opinions collected from the first round were thematically categorised and grouped. The topics were integrated into the survey for the second round and circulated to participants. During the second round, priorities were scored by giving five points to the topic considered most important, and one point to the least important. RESULTS: Through two rounds of consultation, the panel achieved consensus on how to identify food insecurity during pregnancy, with some clear items of consensus related to interventions that could be implemented to address food insecurity during pregnancy. Experts achieved consensus on items that have importance at the institution and policy level, as well as services that exist in the community. The consensus across the spectrum of opportunities for assistance, from the clinical, to community-provided assistance, and on to government policy and practice demonstrate the complexity of this issue, and the multipronged approach that will be required to address it. CONCLUSION: This is the first time such a consultation with experts on hunger and food insecurity during pregnancy has been conducted in Australia. Items that achieved consensus and the importance of the issue suggest several ways forward when working with pregnant women who are hungry and/or food insecure.

Development of a Comprehensive Household Food Security Tool for Families with Young Children and/or Pregnant Women in High Income Countries.

Despite increasing rates of food insecurity in high income countries, food insecurity and its related factors are inconsistently and inadequately assessed, especially among households with young children (0-6 years) and pregnant women. To fill this gap, researchers from the U.S. and Australia collaborated to develop a comprehensive household food security tool that includes the known determinants and outcomes of food insecurity among parents of young children and pregnant women. A five-stage mixed methods approach, including a scoping literature review, key informant interviews, establishing key measurement constructs, identifying items and scales to include, and conducting cognitive interviews, was taken to iteratively develop this new comprehensive tool. The resulting 78-item tool includes the four dimensions of food security (access, availability, utilization, and stability) along with known risk factors (economic, health, and social) and outcomes (mental and physical health and diet quality). The aim of this novel tool is to comprehensively characterize and assess the severity of determinants and outcomes of food insecurity experienced by households with young children and pregnant women.

Factors Associated with Food Insecurity among Pregnant Women and Caregivers of Children Aged 0-6 Years: A Scoping Review.

With a global focus on improving maternal and child nutrition through the 2030 Sustainable Development Goals, it is important to understand food insecurity in pregnant women and families with young children, as food insecurity at these life stages can have ongoing negative health consequences. However, factors that influence food insecurity among this population group are not well understood. This scoping review investigates the factors that influence food insecurity among pregnant women and households with young children aged 0-6 years living in high-income countries. A scoping literature review was conducted using four electronic databases. The search combined terms relevant to: food security, determinants, pregnancy and family and high-income countries. Only full text and English language articles were included. The search identified 657 titles and abstracts; 29 articles were included in the review. A majority (70%) of the studies were conducted in the United States and were mostly either cross-sectional or secondary data analysis of existing population data. Factors associated with food insecurity were identified and grouped into 13 constructs. These included social, economic and health risk factors, food access and utilization factors and health and dietary outcomes. This scoping review identifies the factors associated with food insecurity among pregnant women and families with young children that could be used to better measure and understand food insecurity, which could assist in developing program and policy responses. This review also highlights the lack of literature from high-income countries outside the US.

Systematic Review of Interventions Addressing Food Insecurity in Pregnant Women and New Mothers.

PURPOSE OF THE REVIEW: Food insecurity can have a negative health impact for women during pregnancy and the postpartum period; however, there are a range of barriers to meeting nutritional guidelines during pregnancy. Food insecurity is associated with an increased risk of pregnancy complications and mental and physical health outcomes. This review aims to provide insight into programmes and interventions which have targeted food insecurity in pregnant and early postpartum women. The central research question for this review is as follows: What programmes and interventions have sought to address food insecurity among pregnant and postpartum women? A systematic search of five electronic databases including Medline, CINAHL, Global Health, Embase, and Cochrane was undertaken on August 2021. Key thematic areas searched were food insecurity, pregnancy, nutritional outcomes, and interventions or programmes. Only studies that were published since 2000 in English were considered. RECENT FINDINGS: Eleven studies were included in this review. Studies employed a range of methods and outcomes measures. They were conducted in mostly low- and middle-income countries, and in general, focused on nutritional supplementation, with some studies also incorporating nutrition education or counselling. The findings of this review suggest that while there are a range of possible interventions that seek to address food insecurity and hunger among pregnant and postpartum women, the limited number of robust evaluations or long-term interventions mean that evidence for any one intervention type is limited. Furthermore, the programmes and interventions that do exist are generally embedded within a single context or structure, and as such, may not be able to be widely implemented.

Experiences of Food-Insecure Pregnant Women and Factors Influencing Their Food Choices.

INTRODUCTION: Food insecurity (FI), an inadequate access to healthy, affordable food, is a public health concern primarily driven by material hardship. Optimal antenatal nutrition promotes best health outcomes for the mother and baby. Pregnant women experiencing FI are less able to access healthy foods, increasing the risk of complications such as gestational diabetes and preterm labour. Little is known about the experiences of food-insecure pregnant women in obtaining sufficient, nutritious food, their perceptions regarding antenatal nutrition and how this contributes to their food choices. METHODS: This qualitative study conducted from August to November 2020, during the COVID-19 pandemic, examined the experiences and coping strategies of food-insecure pregnant women, and the factors influencing their food choices. Seven English-speaking food-insecure pregnant women participated in semi-structured interviews. Interview transcripts were thematically analysed, informed by grounded theory methodology. RESULTS: Three themes were identified through analysis of the interviews related to strategies that managed household food supply, factors that influenced food choices, and experiences of pregnancy during the COVID-19 pandemic. As a result of a limited food budget, pregnancy symptoms, the cognitive overload that attends the FI experience, and the acute yet significant impact of the pandemic, food-insecure pregnant women in this study defaulted to cheap and convenient food choices despite acknowledging the importance of eating well for pregnancy. CONCLUSION: FI during pregnancy is burdensome, relentless and undermines women's wellbeing. Supportive strategies within antenatal healthcare settings are urgently required to deliver an equitable health response for vulnerable women.
