Interrelationship between food security status, home availability of variety of fruits and vegetables and their dietary intake among low-income pregnant women

Food insecurity during pregnancy in high-income countries, and maternal weight and diet: A systematic review and meta-analysis

Food insecurity is a well-established obesity driver. Less is known about food insecurity during pregnancy. This review (PROSPERO:CRD42022311669) aimed to explore associations between food insecurity, maternal obesity, gestational weight gain (GWG), and nutrition. Searches included seven databases, gray literature, references, citations, and contacting authors. Observational studies reporting data from January 1st, 2008 to 21 November 2023 in high-income countries were included. Duplicate screening, data extraction, and quality assessments were performed. Random effects meta-analysis estimated odds ratios (OR), mean difference (MD), and 95% confidence intervals (CI). Narrative synthesis was conducted when data could not be pooled. Database searches identified 22,272 results; 20 studies were included (n = 19 North America, n = 1 Europe; n = 32,803 women). Food insecurity significantly increased obesity (OR 1.53 95%CI 1.39, 1.66), but not underweight (OR 1.12 95%CI 0.89, 1.34) or overweight (OR 1.18 95%CI 0.90, 1.46). Food insecurity significantly reduced GWG (MD -0.42 kg 95%CI -0.62, -0.22) and increased inadequate GWG (OR 1.16 95%CI 1.05, 1.28), but not excessive GWG (OR 1.04 95%CI 0.96, 1.13). Diet outcomes were inconsistent, with some evidence of reduced vitamin E and diet quality and increased red/processed meat consumption. Further studies outside of North America are needed to inform practice and policy to support maternal health.

Associations between food insecurity and child and parental physical, nutritional, psychosocial and economic well-being globally during the first 1000 days: A scoping review

Food insecurity affects billions of individuals annually and contributes to myriad poor health outcomes. Experiences of food insecurity may be particularly harmful during the first 1000 days, but literature on the topic has not been synthesized. We therefore aimed to characterize all available studies examining associations between food insecurity and nutritional, psychosocial, physical and economic well-being among parents and children during this period. We implemented a standardized search strategy across 11 databases. Four researchers screened 10,257 articles, 120 of which met the inclusion criteria. Most studies were conducted in Sub-Saharan Africa (43.3%), followed by North America (20.8%). Studies were primarily quantitative (95.8%), cross-sectional (70.0%) and focused on women (pregnant or post-partum, 48.3%) or women and children (15.8%). Physical health outcomes were the most investigated (n = 87 studies), followed by nutritional (n = 69), psychosocial (n = 35) and economic well-being (n = 2). The most studied associations were between food insecurity and stunting (n = 15), maternal depression (n = 12), child dietary diversity (n = 7) and maternal body mass index (n = 6). The strength of evidence for the observed associations varied across populations as well as within and between examined outcomes. We recommend that future studies recruit more diverse study populations, consider temporality of relationships, use instruments that facilitate cross-site comparisons, measure individual-level food insecurity and outcomes most likely to be impacted by food insecurity, evaluate contextual factors that may modify the effects of food insecurity and employ analytic techniques that permit assessment of causal pathways.

Evidence-Based Eating Patterns and Behavior Changes to Limit Excessive Gestational Weight Gain: A Scoping Review

BACKGROUND

International prenatal care guidelines set a standard for clinicians to discuss gestational weight gain with their patients along with the complications associated with prepregnancy obesity and excessive gestational weight gain. Clinicians often lack evidence-based eating, nutrition, and activity strategies to share with patients.

METHODS

This systematic review aimed to find eating patterns and behaviors that could be used safely during pregnancy to limit excessive gestational weight gain. PubMed, MEDLINE, and Web of Science were searched for research or systematic reviews performed in the United States or Canada and published in English from 2013 to 2023. Keyword search terms included weight, manage, behavior, strategy, strategies, gestational weight gain, and nutrition. Excluded research used pediatric or adolescent populations, restrictive diets, such as no carbohydrate or no fat diets, fasting, bariatric surgery, weight loss medications, private industry or profit-earning programs using food brands, or specific diet programs.

RESULTS

A total of 844 abstracts were retrieved, with 103 full-text studies reviewed. Behaviors had to be useful for maintaining a healthy gestational weight gain and had to be safe for use during pregnancy. Behaviors useful during pregnancy included meal planning, home meal preparation, portion control, using diets such as the Mediterranean diet, the low-glycemic index diet, and the Dietary Approaches to Stop Hypertension diet (DASH), regular physical activity, sleeping 6-7 h a night, mindful eating, intuitive eating, and regular seif-weighing.

CONCLUSION

The evidence-based strategies outlined in this review are safe for use during pregnancy and can assist patients in avoiding excessive gestational weight gain while maintaining the nutrition needed for healthy fetal growth.

Trends, Prevalence, and Risk Factors of Food Insecurity Among Pregnant and Postpartum Women in the United States: Findings from the 2019-2021 National Health Interview Survey

Background: Despite the widespread food insecurity in the United States, there is limited research investigating its prevalence among pregnant women and the potential impact it has on maternal and child health outcomes. This study examined trends in the prevalence of, and investigated risk factors for, food insecurity among peripartum women, using a nationally representative sample in the United States. Materials and Methods: This cross-sectional study included pregnant and postpartum women aged 18-49 years who reported being currently pregnant or pregnant in the past 12 months and who participated in the National Health Interview Survey from 2019 to 2021. Weighted multivariable logistic regression analysis was used to estimate associations with food insecurity. Results: A total of 1,527 pregnant women, weighted to represent 5,588,192 women in the United States, were included in the analysis. Overall, from 2019 to 2021, 10.8% of peripartum women were food insecure. The prevalence of food insecurity changed substantially between 2019 and 2021 (2019: 10.6% confidence interval [95% CI: 8.7-13.5], 2020: 16.0% [95% CI: 10.9-22.8], 2021: 6.2% [95% CI: 4.2-9.1]). The adjusted odds of food insecurity were significantly higher among pregnant and postpartum women in 2020 (aOR 2.15), who had a health insurance coverage (aOR 2.98) and who had an unmet health care need in the preceding 12 months (aOR 6.52). Conclusion: We found that food insecurity was common among peripartum women between 2019 and 2021 and was exacerbated by the COVID-19 pandemic. Identifying the factors that predispose peripartum women to the risk of food insecurity can guide the development and implementation of targeted interventions aimed at reducing the adverse impact of food insecurity on perinatal and infant health.

Revisiting food insecurity gender disparity

Previous research has shown that woman-headed households, more than man-headed ones, experience food insecurity. The purpose of this article is to contribute on the determinants that are linked to this gender disparity. Using a nationally representative dataset from Chile, we found that food security household head gender disparity is associated with marital status (having or not a partner) and household composition (having children or seniors). In contrast, gender disparity is not strongly associated with household income and household head educational differences. In this way, we expect to bring evidence to inform new alternatives that help mitigate food security gender disparity.

Food security and diet quality in a racially diverse cohort of postpartum women in the USA

Food insecurity has been associated with poor diet, but few studies focused on the postpartum period - an important time for women's health. We examined associations between food security and diet quality in postpartum women and assessed whether participation in federal food assistance programmes modified this potential relation. Using longitudinal data, we analysed the association between food security at 3 months postpartum and a modified Alternate Healthy Eating Index-2010 (AHEI) at 6 months postpartum (excluding alcohol). We conducted multivariable linear regressions examining associations between food security and AHEI. We assessed two food assistance programmes as potential effect modifiers. The sample included 363 postpartum women from the Nurture study, located in the Southeastern USA (2013-2017). Among women, 64·4 % were Black and 45·7 % had a high school diploma or less. We found no evidence of an interaction between food security and two federal food assistance programmes. In adjusted models, marginal, low and very low food security were not associated with AHEI. However, low (β: -0·64; 95 % CI -1·15, -0·13; P = 0·01) and very low (β: -0·57; 95 % CI -1·02, -0·13; P = 0·01) food security were associated with greater trans fat intake. Food security status was not associated with overall diet quality but was associated with higher trans fat (low and very low) and more moderate alcohol (marginal) intake. Future studies should assess the consistency and generalisability of these findings.

Nutrition Literacy Among Latina/x People During Pregnancy Is Associated With Socioeconomic Position

BACKGROUND

During pregnancy, Latina/x people experience nutrition and nutrition-related health inequities. Nutrition literacy is a potential factor impacted by these inequities. However, the nutrition literacy level of Latina/x people during pregnancy is not well investigated.

OBJECTIVES

The study aimed to assess the nutrition literacy level of Latina/x people during pregnancy and explore the association of nutrition literacy with socioeconomic position.

DESIGN

This was a cross-sectional study of data collected from 2016 to 2018 within the double-blinded, randomized clinical trial Assessment of Docosahexaenoic Acid on Reducing Early Preterm Birth.

PARTICIPANTS/SETTING

A total of 112 Latina/x people during pregnancy from the Kansas City metro area were included in this study.

MAIN OUTCOME MEASURES

Nutrition literacy level assessed between 12 and 20 gestational weeks using the Nutrition Literacy Assessment Instrument, both in English and Spanish.

STATISTICAL ANALYSES PERFORMED

Descriptive measures were used to describe the nutrition literacy level during pregnancy. Multiple logistic regression models were used to examine the association between low nutrition literacy and socioeconomic position, adjusting for age and race.

RESULTS

In this study, most participants demonstrated low nutrition literacy during pregnancy. Those with low nutrition literacy were 2 times more likely to have low annual household income (odds ratio [OR] = 2.74, 95% confidence interval [CI]: 0.99-7.59), 3 times more likely to prefer Spanish as their primary language of communication (OR = 3.03, 95% CI: 0.95-9.67), and 7 times more likely to be uninsured (OR = 7.47; 95% CI: 1.57-35.64).

CONCLUSIONS

Nutrition literacy scores during pregnancy were associated with variables of socioeconomic position. Future research should focus on nutrition literacy associations with health outcomes during pregnancy and interventions to improve the nutrition literacy level of primarily Spanish-speaking people who have low household incomes and are uninsured.

Perceptions of the local food environment and fruit and vegetable intake in the Eastern Caribbean Health Outcomes research Network (ECHORN) Cohort study

INTRODUCTION

Studies conducted in the US and other high-income countries show that the local food environment influences dietary intakes that are protective for cardiovascular health.However, few studies have examined this relationship in the Caribbean. This study aimed to determine whether perceptions of the local food environment were associated with fruit and vegetable (FV) intake in the Eastern Caribbean, where daily FV intake remains below recommended levels.

METHODS

Cross-sectional analysis of Eastern Caribbean Health Outcomes Research Network Cohort Study (ECS) baseline data (2013-2016) from Barbados, Puerto Rico, Trinidad and Tobago, and US Virgin Islands was conducted in 2020. The National Cancer Institute Dietary Screener Questionnaire was adapted to measure daily servings of FV. Existing scales were used to assess participant perceptions of the food environment (availability, affordability, and quality). Chi-square tests and Poisson regression were used for analyses.

RESULTS

Participants reported eating one mean daily serving of FV. Mean daily intake was higher among those who perceived FV as usually/always affordable, available, and high quality. Multivariate results showed statistically significant associations between FV and affordability. Persons who perceived FV as affordable had 0.10 more daily servings of FV compared to those who reported FV as not always affordable (p = 0.02). Food insecurity modified the association between affordability and FV intake.

CONCLUSIONS

This study highlights the importance of affordability in consumption of FV in the Eastern Caribbean, and how this relationship may be modified by food insecurity.

Factors Associated with Home Food Environment in Low-Income Overweight or Obese Pregnant Women

Limited research has examined factors associated with home food availability. This study investigated the associations among demographics, body mass index category, stress, and home food availability among low-income overweight or obese pregnant women. This cross-sectional study enrolled 332 participants who were non-Hispanic black or white. We performed logistic regression modeling for unprocessed food, processed food, overall ultra-processed food, and three subcategories of ultra-processed food (salty snacks, sweet snacks and candies, and soda). Black women were less likely than white women to have large amounts of processed foods (OR = 0.56), salty snacks (OR = 0.61), and soda (OR = 0.49) available at home. Women with at least some college education or at least a college education were more likely to have large amounts of unprocessed food (OR = 2.58, OR = 4.38 respectively) but less likely to have large amounts of soda (OR = 0.44; OR = 0.22 respectively) available at home than their counterparts. Women with higher stress were less likely to have large amounts of unprocessed food available at home (OR = 0.58) than those with lower stress. Home food availability varied by race, education, and levels of stress in low-income overweight or obese pregnant women.

Household Food Security, Nutritional Intake, and Nutritional Status of Pregnant Women in the Central Tapanuli Regency

BACKGROUND: Malnutrition that occurs during pregnancy can result in inadequate household food security so that it will affect the baby to be born. AIM: This study aims to determine household food security, nutrient intake, and nutritional status of pregnant women in the Central Tapanuli Regency. METHODS: This research is part of the DRPM research with the title of improving the nutrition of pregnant women and the success of breastfeeding immediately after birth through strengthening household food security in the Central Tapanuli Regency. The stages of this research are to identify the level of household food security and nutrient intake as well as the nutritional status of pregnant women. The study was conducted using observation and interviews as well as measuring LILA, examination of Hb levels, and iodine levels in the urine of 131 pregnant women purposively in eight districts of the Central Tapanuli. RESULTS: The household food security of status that is food insecure is 18.3%. The nutritional status of pregnant women with anemia was 58.7% and those with SEZ were 19.1% fiber with the low levels of iodine in the urine as much as 63.9%. Adequate intake of energy nutrients is 42% and sufficient protein is 38.9%. There was a significant relationship between food security status and energy intake (p = 0.000; OR = 53.9) and protein intake (p = 0.004; OR = 4.1). CONCLUSIONS: There is a significant relationship between household food security status with energy and protein intake of pregnant women. Increased consumption of foods containing animal protein is recommended for pregnant women related to household food insecurity.

Relationships Among Neighborhood Poverty, Access to Healthy Food, and Diabetes Self-Management in Women Who Received Perinatal Nurse Home Visits

OBJECTIVE

To examine the relationships among neighborhood poverty, access to healthy food, and diabetes self-management in pregnant women in an urban setting who received perinatal nurse home visits.

DESIGN

Exploratory descriptive secondary analysis of existing individual-level and neighborhood-level data.

SETTING

Philadelphia, Pennsylvania, United States.

PARTICIPANTS

Women who were pregnant, had diabetes, and were enrolled in the citywide perinatal nurse home visiting program because of their diabetes (N = 264).

METHODS

We retrieved neighborhood-level aggregated data on poverty and access to healthy food from PolicyMap, a geographic information system. We retrieved individual-level data from a clinical research database. Access to healthy food was operationalized at the individual level by reported use of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). We operationalized diabetes self-management as good or poor glycemic control. We conducted descriptive and logistic regression analyses.

RESULTS

We found no relationship between neighborhood-level poverty and neighborhood-level access to healthy food with women's glycemic control. However, at the individual level, use of the WIC program was associated with glycemic control (p = .034). Participants who reported not using this program were two times more likely to have poor glycemic control than those who did (OR = 2.045, 95% confidence interval [1.003, 2.045]).

CONCLUSION

It is important to understand how the complex interplay between neighborhoods and individual factors of poverty and access to healthy food influences health outcomes among pregnant women. The WIC program may mediate neighborhood influence on diabetes self-management. Future research is warranted on how this program and nurse home visiting services can optimize maternal health outcomes among women who have diabetes during pregnancy.

Relative Importance of Determinants of Changes in Eating Behavior during the Transition to Parenthood: Priorities for Future Research and Interventions

Background: Healthy eating behavior throughout pregnancy and postpartum is important. This study aimed to investigate the perceived sex-specific importance of determinants of changes in eating behavior during pregnancy and postpartum. Methods: Fifty-four determinants were rated by first-time parents (n = 179) on their impact. Experts (n = 31) rated the determinants in terms of their modifiability, relationship strength, and population-level effect from which a “priority for research”-score was calculated. Results: During pregnancy, the three highest rated determinants by women were “health concerns”, “physiological changes”, and “fatigue”. Men perceived “health concerns”, “health consciousness”, and “influence of the pregnant partner” as important. Postpartum, the three highest rated determinants by women were “adaptation to rhythm of baby”, “baby becomes priority”, and “practical constraints because of the baby”. Men perceived “adaptation to rhythm of baby”, “fatigue”. and “(lack of) anticipation” as important. According to the experts, “professional influence”, “food knowledge”, and “home food availability” received high priority scores for both sexes and during both periods. Conclusions: Priority for research and interventions should go towards tailored family-based approaches focusing on food education in a broad sense taking into account aspects such as health consciousness, self-efficacy skills, and the social and home food environment while being supported by healthcare professionals.

Adolescent-Reported Food Insecurity: Correlates of Dietary Intake and School Lunch Behavior

Much of what is known about food insecurity (FI) experiences for young people is based on caregiver report. As such, our understanding of relationships between youth FI and dietary intake (DI) may be limited, particularly among adolescents who often eat away from home. This study examined relationships between youth-reported past-month FI, past-week DI, and school lunch behavior. Data are from middle and high school participants in the 2019 Minnesota Student Survey (N = 125,375), one of the longest-running youth surveys in the US. Logistic regression assessed relationships between FI and DI, including fruit, vegetable, milk, sugar-sweetened beverage (SSB), and fast food consumption, and school lunch behavior, adjusting for demographic, physical, and emotional health indicators. Past-month FI was associated with reduced odds of meeting minimum thresholds for daily fruit, vegetable, and milk intake, and increased odds of daily SSB and frequent fast food consumption. Among food-insecure students, no participation in the National School Lunch Program (NSLP) or NSLP participation uncertainty was associated with increased odds of skipping lunch. Findings suggest the importance of clinical and community innovations to prevent the loss of nutritional quality in favor of energy density for youth and families experiencing FI.

Methodologies for assessing the household food availability in the context of food (in)security: a systematic review

This article aims to identify the methods used to assess household food availability in studies on food and nutritional security and to discuss its methodological aspects. Systematic review elaborated according to the PRISMA method. We searched at PubMed; Scielo and Lilacs databases, and studies that used methods of assessing the availability of food at home were included. In the end, 19 papers composed the review. Food availability was predominantly assessed for a seven days period and from a single data measurement. Other variables were also observed in the studies, such as socio-demographic data and expenditure on food. Among the limitations to assess the food availability at home, we can highlight the difficulty in measuring the food distribution among family members and the lack of information on the variability of this availability. Such assessment can be improved by investigating the strengths and weaknesses of the instruments for greater detail and accuracy of the information. We recommend the development and validation of specific instruments capable of effectively measure the food availability at the household level.

Differences in reporting food insecurity and factors associated with differences among Latino fathers and mothers

BACKGROUND

Food security status has been assessed as a representative score for households; however, different members in the same household may perceive and report food insecurity differently. A high prevalence of food insecurity has been reported among Latino households, therefore understanding differences in reporting food insecurity by Latino father-mother dyads may improve accuracy of assessment and plans to address food insecurity. This study aimed to 1) determine demographic characteristics and/or food-related factors associated with perceptions of food security status among Latino father-mother dyads, and 2) identify factors associated with discordance in perceptions of food insecurity between dyads.

METHODS

Baseline data were used from a community-based, youth obesity prevention program among Latino families (n = 106 father-mother dyads). Food security was assessed with a 2-item food insecurity screen. Logistic regression models were used to evaluate associations between reporting food security status and predictor variables for fathers, mothers, and dyad-discordant responses.

RESULTS

Food insecurity was reported by 39% of fathers and 55% of mothers. Adjusted odds of reporting food insecurity were significantly higher for fathers perceiving their neighborhood was unsafe vs. safe (OR: 3.7, p < 0.05) and reporting lower vs. higher household income (OR: 3.2, p < 0.05). Adjusted odds of reporting food insecurity were significantly higher for mothers perceiving their neighborhood was unsafe vs. safe (OR: 4.1, p < 0.01) and reporting lower vs. higher home availability of fruit and vegetable (OR: 5.5, p < 0.01). Dyad discordance in reporting food security status occurred in 24% of the dyads. Adjusted odds of dyad discordant reports of food insecurity status were significantly higher for dyads reporting discordant responses regarding previous nutrition education (OR: 3.4, p < 0.05) and higher home fruit and vegetable accessibility (OR: 3.1, p < 0.05) compared to dyads reporting concordant responses. Among the 28 dyads who reported discordant nutrition education participation, 21 reported that fathers had never participated but mothers had participated more than once.

CONCLUSIONS

Differential factors were associated with reporting food security among Latino father-mother dyads. Nutrition education for fathers that improves awareness of home food supplies and a better understanding of how food accessibility influences maternal perceptions may improve dyad discordance in reporting household food security.

Prevalence and factors associated with anaemia in pregnant women in Cascades Region of Burkina Faso in 2012

Introduction

anaemia in pregnancy is a public health concern in Burkina Faso. This study aims at identifying the factors associated with the prevalence of anaemia in pregnant women at a regional level in Burkina Faso.

Methods

we conducted a cross-sectional study in the region called “Cascades”, located at the Western part of Burkina Faso. The study population included all pregnant women who attended antenatal care clinics in all public peripheral health facilities (districts) between May and June 2012 and agreed to participate in the study. They provided blood sample from which we measured the haemoglobin concentration using the Hemocue® system. The factors associated with anaemia in the study population were identified through multiple logistic regressions.

Results

the prevalence (95% CI) of anaemia in pregnancy in the Cascades region was 58.9% (56.6% - 61.2%). Anaemia in pregnancy was more common in district of Banfora (OR = 1.40; 95% CI: 1.07-1.83), among housewives (OR = 2.96; 95% CI: 1.10-8.0), in the Mossi ethnic group (OR = 1.39; 95% CI: 1.04-1.85) and among the wives of farmers and artisans (OR = 2.55; 95% CI: 1.59-4.07). Anaemia in pregnancy was less frequent among women who drank local beer (OR = 0.68; 95% CI: 0.49-0.94).

Conclusion

the prevalence of anaemia in pregnancy is high in Burkina Faso. Improving women's income level may contribute to reduce it. Further studies are needed to elucidate the link between the consumption of local beer, the local diet practices and anaemia in pregnant women.

Food insecurity: Its prevalence and relationship to fruit and vegetable consumption

BACKGROUND

Food insecurity in UK households is a substantial and growing concern. The present study identified those at risk of food insecurity and explored the relationship between food security and fruit and vegetable consumption.

METHODS

Data were examined from the Food and You survey (2016) for a large representative sample (n = 3118) living in England, Wales and Northern Ireland. A 'Food Security Score' and a 'Food Changes Score' (relating to financially driven changes to food habits) were compiled and relationships with fruit and vegetable consumption were examined.

RESULTS

The prevalence of marginal, low and very low food security was 12.6%, 5.4% and 2.8%, respectively. Significant correlations were observed between food security and fruit and vegetable consumption. Food security and food changes, independently, were significant predictors for fruit and vegetable consumption. With every unit increment in the Food Security Score (i.e., more food insecure), an 11% decrease in the odds of being a high fruit and vegetable consumer was evident. Likewise, the odds of being a high fruit and vegetable consumer decreases by 5% with every increment in the financially driven Food Changes Score.

CONCLUSIONS

A notable proportion (more than one-fifth) experienced marginal, low or very low food security. Food insecurity and financially driven food changes were accompanied by decreases in the odds of being a high fruit and vegetable consumer. Findings underline the potential consequences of food insecurity, and point to further work aiming to examine other dietary implications, as well as strategies to mitigate against food insecurity and its detriment.

Food shopping, home food availability, and food insecurity among customers in small food stores: an exploratory study

Customers who frequently shop in small food stores (e.g., convenience stores) may face numerous challenges to procuring healthful food for their household, and these may vary by food security status. The purpose of this study is to examine associations between food security and food shopping-related behaviors among frequent shoppers at small stores. Our sample included participants from customer intercept interviews at small food stores in an urban area. A follow-up in-home visit with a subset of customers who reported frequently shopping in these stores (≥1/week; n = 78) included a survey and researcher-administered home food inventory. Food security status was identified via the U.S. Household Food Security Survey Six-Item Short Form. Outcomes included shopping frequency and money spent by store type (e.g., small vs. large), home-to-store distance, and observed home availability of fruits, vegetables, and obesogenic foods. We estimated associations between food security status and each outcome, adjusting for demographic and poverty-related confounders. Participants were 56% female and 65% people of color; 45% received Supplemental Nutrition Assistance Program benefits and 54% experienced food insecurity in the past year. Unadjusted models indicated several significant associations: compared to those who were food secure, food-insecure participants shopped for food/beverages at small stores more times per month, spent more on food/beverages at dollar stores, and had less home availability of fruit and obesogenic foods. Associations remained significant (p = .04) between food insecurity and shopping frequency in adjusted models. Interventions requiring or incentivizing small food stores to stock healthful products could be important for improving access to nutritious food for food-insecure persons.

The accelerator, the brake, and the terrain: associations of reward-related eating, self-regulation, and the home food environment with diet quality during pregnancy and postpartum in the pregnancy eating attributes study (PEAS) cohort

Background

Neurobehavioral factors, including reward-related eating and self-regulation, in conjunction with the food environment, may influence dietary behaviors. However, these constructs have not been examined in pregnancy and postpartum, a time of changing appetite and eating behaviors, and when dietary intake has implications for maternal and child health. This study examined associations of reward-related eating, self-regulation, and the home food environment with pregnancy and postpartum diet quality.

Methods

Participants in the Pregnancy Eating Attributes Study observational cohort were enrolled at ≤12 weeks gestation and followed through one-year postpartum. Pregnancy and postpartum Healthy Eating Index-2015 (HEI-total), and adequacy and moderation scores, respectively, were calculated by pooling 24-h diet recalls administered each trimester and during 2, 6, and 12 months postpartum. Participants completed four measures of reward-related eating – Modified Yale Food Addiction Scale (mYFAS), Power of Food Scale (PFS), Multiple Choice Procedure (MCP), and Reinforcing Value of Food Questionnaire (RVFQ); two measures of self-regulation – Barratt Impulsiveness Scale (BIS) and Delay of Gratification Inventory (DGI); and a Home Food Inventory (HFI), yielding obesogenic (OBES) and fruit/vegetables (FV) scores. Linear regression analyses estimated associations of reward-related eating, self-regulation, and home food environment with diet quality during pregnancy and postpartum, adjusting for sociodemographic characteristics.

Results

Pregnancy HEI-total was inversely associated with PFS (β = − 0.14 ± 0.05, p = 0.009), mYFAS(β = − 0.14 ± 0.06, p = 0.02), 2 of the 5 RVFQ indices, MCP (β = − 0.14 ± 0.05, p = 0.01), and DGI food subscale (β = 0.23 ± 0.05, p < 0.001), but associations of postpartum HEI-total with reward-related eating measures and self-regulation were small and not statistically significant. Pregnancy and postpartum HEI-total were associated inversely with HFI-OBES (β = − 0.17 ± 0.06, p = 0.004 and β = − 0.19 ± 0.07, p = 0.006, respectively), and positively with HFI-FV (β = 0.21 ± 0.05, p < 0.001 and β = 0.17 ± 0.06, p = 0.009, respectively).

Conclusions

Associations of poorer diet quality with greater reward-related eating during pregnancy but not postpartum suggests the need to better understand differences in the determinants of eating behaviors and approaches to circumvent or moderate reward-related eating to facilitate more optimal diet quality across this critical period.

Reward-related eating, self-regulation, and weight change in pregnancy and postpartum: the Pregnancy Eating Attributes Study (PEAS)

Background/Objectives.

Reward-related eating is hypothesized to underlie risk for weight gain in obesogenic environments, but its role is unknown during pregnancy and postpartum when weight change is normative, but excess weight gain and weight retention are common. This study examined associations of self-reported reward-related eating, self-regulation, and the home food environment with excessive gestational weight gain (GWG) and postpartum weight change.

Subjects/Methods.

Participants in the Pregnancy Eating Attributes Study observational cohort were enrolled at ≤12 weeks pregnancy and followed through one-year postpartum (458 recruited; 367 retained through delivery). Participants completed four measures of reward-related eating – Modified Yale Food Addiction Scale, Power of Food Scale, Multiple Choice Procedure, and a Reinforcing Value of Food Questionnaire; two measures of self-regulation – Barratt Impulsiveness Scale and Delay of Gratification Inventory; and a Home Food Inventory. Measured weight and skinfolds were obtained. Multinomial logistic and multiple linear regression analyses estimated associations of reward-related eating, self-regulation, and home food environment with excessive GWG, gestational fat gain, postpartum weight change, and percent of GWG retained.

Results.

Excessive GWG was associated with food reinforcement intensity, but not with any other measure of reward-related eating, self-regulation, or home food environment. Greater gestational fat gain was associated only with higher Multiple Choice Procedure. Postpartum weight change and percent of GWG retained were associated with greater Delay of Gratification and obesogenic home food environment, but not with any measure of reward-related eating or with impulsivity.

Conclusions.

Findings do not support the hypothesis that self-reported reward-related eating is associated with weight outcomes in pregnancy and postpartum but indicate a relation of Delay of Gratification with postpartum weight retention. Further research using both surveys and objective measures of reward-related eating is needed to advance our understanding of the relation of reward-related eating with weight changes during this critical period of a woman’s life.

Food assistance programs and income are associated with the diet quality of grocery purchases for households consisting of women of reproductive age or young children

Women's diet quality during reproductive years and children's diet quality during early life influence long term health. Few studies have evaluated the impact of food assistance programs and income on the diet quality of grocery purchases made by households consisting of women of reproductive age and young children. We used data from the Food Acquisition and Purchase Survey 2012-2013 (FoodAPS) to evaluate how household income, Special Supplemental Nutrition Assistance Program for Women, Infants and Children (WIC) participation, and Supplemental Nutrition Assistance Program (SNAP) participation are related to the diet quality of grocery purchases made by households that include women of reproductive age or young children (n = 2436). The diet quality of household grocery purchases was assessed with the Healthy Eating Index (HEI) 2015. HEI-2015 total score (0-100) and component scores were evaluated according to household income (eligible for WIC: income-to-poverty ratio ≤ 185%; ineligible for WIC: income-to-poverty ratio > 185%) and WIC, SNAP, and WIC + SNAP participation. Median HEI-2015 total score was lowest among SNAP households and highest among income ineligible for WIC and WIC households (47.2 and 54.1, respectively). Compared to income ineligible for WIC households, WIC + SNAP and SNAP households had lower HEI-2015 whole fruit (β = -0.30, 95% CI: -0.59, -0.01 and β = -0.41, 95% CI: -0.63, -0.20, respectively) and total vegetable scores (β = -0.58, 95% CI: -0.83, -0.32 and β = -0.27, 95% CI: -0.45, -0.08, respectively). The diet quality of grocery purchases in this population varies according to household income and food assistance participation.

Household food insecurity associated with gestacional and neonatal outcomes: a systematic review

BACKGROUND

Food insecurity (FI) occurs when people lack secure access to sufficient amounts of safe and nutritious food. FI has been associated with negative effects on human health, including during the prenatal and neonatal periods. The objective of this study is to evaluate the consequences of FI for pregnant women's and newborns' health.

METHODS

A literature search was performed with three independent researchers based on the PRISMA guidelines; the search covered the period of November 2008 to July 2019 and was conducted in the following databases: the US National Library of Medicine at the National Institutes of Health (PubMed), Latin American and Caribbean Health Sciences (LILACS), Cochrane Library, Web of Science, Embase, Scopus and OpenGrey. The terms and descriptors were defined by consulting the Medical Subject Headings (MeSH) and Health Sciences Descriptors (DeCS) platforms and mainly included "food security", "food insecurity", "pregnancy" and "newborn". The studies were selected through a title and abstract review and then a reading of the full text. The quality of the studies and the risk of bias were analysed based on the criteria defined in the "Joanna Briggs Institute Reviewers' Manual" and by Guyatt and colleagues for interventional studies. The population, study design, FI measurement instruments, FI proportions, outcomes, confounders and results were extracted from the 37 studies that were selected according to the eligibility and quality criteria.

RESULTS

FI ​​proportions ranged from 5.2 to 87%. Most studies were conducted with African populations (42.2%) and applied globally used scales to assess FI (56.7%); 27% of the studies adapted scales. There were wide variations in the instruments used to estimate FI. The main outcomes related to FI included stress, anxiety and depression during pregnancy, followed by dietary quality and dietary diversity. Associations of FI with birth defects, neonatal mortality and the early introduction of animal milk to the infant's diet were also observed.

CONCLUSIONS

It is necessary to pay attention to the diversity of FI measurement instruments before FI results are compared. FI can be a risk factor for depression and stress during pregnancy, as well as for neonatal mortality, newborn health problems and breastfeeding interruption.

Dietary practices and associated factors among pregnant women in West Gojjam Zone, Northwest Ethiopia

Background

The optimal dietary practice is a critical requisite for maternal nutrition. However, the majority of Ethiopian pregnant women have inadequate nutrient intakes. These may be due to their poor dietary habits. Identifying factors affecting the dietary practices of pregnant women is crucial to design appropriate interventions. In this country, the dietary practices of pregnant women and determinants are not well studied. Therefore, the purpose of this study was to assess the dietary practices and associated factors among pregnant women in West Gojjam Zone, Northwest Ethiopia.

Methods

A community-based cross-sectional study was carried out among 712 pregnant women from May to August 2018. Quantitative data complemented with a qualitative method. Pregnant women were selected using a cluster sampling technique. Structured questionnaires were utilized for data collection. Data were entered into Epi-Info version 7.2.2 and exported to SPSS version 23 software for analysis. Data were described using frequencies and mean. A logistic regression analysis was done.

Three focus group discussions and 17 key-informant interviews were conducted for the qualitative data. Focus group discussion participants were mothers, husbands, and health professionals. Typical case and homogeneous sampling techniques were used for the key-informant interviews and focus group discussions, respectively. Thematic analysis was used for the qualitative data.

Results

Only 19.9% of respondents had appropriate dietary practices. On the multivariable logistic regression analyses, being food secure [AOR = 2.25, 95% CI: (1.1, 4.5)], having high edible crop production [AOR = 2.00, 95% CI: (1.2, 3.2)] and a favorable attitude [AOR = 1.69, 95% CI: (1.1, 2.6)] were significantly associated with the appropriate dietary practices of pregnant women. In the qualitative study, lack of knowledge on maternal diet, cultural prohibition, and knowledge gap of the professionals were barriers that interfere with dietary practices during pregnancy.

Conclusion

Pregnant women in the study area are found to have suboptimal dietary practices. Therefore, health professionals should give regular nutrition counseling using cards and role models for promoting diversified food production and consumption.

Food availability and food insecurity in households in the state of Tocantins, Northern Brazil

ABSTRACT Objective To assess the relationship between food availability, food insecurity and socioeconomic and demographic characteristics of households in the urban area of the state of Tocantins. Methods Population-based, cross-sectional study conducted in 594 households in the urban area of 22 municipalities in the state of Tocantins. A survey was carried out in the households, to collect socioeconomic and data, and assess food insecurity using the Brazilian Food Insecurity Scale. Further a food availability questionnaire was applied by the interviewer with the head of the family, who reported on the food and drinks available at home in the last 30 days. The description of the food available in the households resulted in a total of 142 food items that were grouped according to the NOVA classification of foods. demographic Results It was found that 63.3% of households were in a situation of food insecurity. The median caloric availability found was 2,771.4kcal/per capita/day, with the largest caloric contribution coming from fresh and minimally processed foods, regardless of the degree of food insecurity. Food availability was affected by socioeconomic vulnerability and the situation of food insecurity in the families.

A comparison of maternal feeding responses to child fussy eating in low-income food secure and food insecure households

Children learn to like a wide variety of healthy foods through exposure in their early feeding environment. While some children may reject foods during this learning process, parents may perceive persistent refusal as 'fussy' or 'picky' eating. Low-income parents may provide fussy children with a narrow range of foods that they will like and accept to avoid food and economic waste; inadvertently limiting children's exposure to a variety of healthy foods. This 'risk aversion' to food rejection may be particularly salient in food insecure households where resources are further constrained. We aimed to examine if food insecurity modifies the relationship between child fussy eating and parents' food provision and feeding with respect to exposure to a variety of healthy foods. Australian mothers residing in a low-income community (N = 260) completed a cross-sectional survey on their preschool-aged child's 'food fussiness', household food insecurity and food exposure practices. Food exposure practices included the home availability of fruit and vegetables, and children's tasting of a variety of fruit and vegetables (food provision); and whether parents prepared alternative meals for their child (feeding). Mothers reporting food insecurity (11%) were less likely to have fruit frequently available in the home compared to mothers reporting food security. Food insecurity moderated the relationship between fussy eating and food exposure practices insofar that food secure mothers were more likely to prepare alternative meals for fussier children. Family resources and child fussy eating behaviours are identified as important contextual factors in food provision and feeding. Findings from the current study suggest that health professionals, researchers and policymakers tailor interventions to consider both the needs of families and child eating characteristics.
