Household food insecurity is associated with depressive symptoms among low-income pregnant Latinas

Household food insecurity and symptoms of anxiety and depression during pregnancy: Systematic review and meta-analysis

Household food insecurity (HFI) has been related to adverse maternal-child health outcomes and mental health worsening during pregnancy. Few studies evaluated the temporal association between HFI and anxiety and depressive symptoms in pregnant women, and this association remains not completely understood. This study aimed to systematically review the association between HFI and symptoms of depression and anxiety in pregnant individuals. The systematic review protocol was registered in the International Prospective Register of Systematic Reviews (CRD42022373615). Systematic searches were conducted on 10 electronic databases and grey literature. Two researchers independently conducted the study selection, data extraction process, and the risk of bias assessment. Random-effects meta-analysis models were used, and I2 > 40% indicated high heterogeneity across studies. Eighteen articles were included for the systematic review, comprising n = 27,882, and a total of 18,987 pregnant individuals aged between 14 and 45 years were included in the meta-analysis. The prevalence of HFI reported in studies ranged from 12.6% to 62.1% (n = 17). The prevalence of depressive and anxiety symptoms ranged from 18% to 49% (n = 11) and 23% to 34% (n = 2), respectively. HFI during pregnancy was associated with increased odds of experiencing symptoms of depression [(OR: 2.52; 95% CI: 2.11-3.02), I2 = 73.23%]. The quality of evidence was very low due to high heterogeneity. Our findings highlighted the association between HFI and depression symptoms during pregnancy. Findings from this study suggest the importance of assessing HFI and mental health during pregnancy.

The Happy Child Program's Intersectionality: Prenatal Home Visit Frequency, Food Insecurity Risk, Symptoms of Depression, and Parental Practices in Brazilian Women Assisted during Pregnancy

Food insecurity (FI) is a critical issue in developing countries, particularly in low-resource settings, where it can worsen women's mental health. Psychosocial factors such as low household income, limited education, multiparity, and vulnerability are linked to depressive symptoms during pregnancy. Additionally, the family environment influences parental practices, which may impact mental health. This study evaluates the association of socioeconomic factors, parental practices, FI risk, and home visit frequency with depressive symptoms in pregnant women enrolled in the Happy Child Program (Programa Criança Feliz-PCF) in the Federal District, Brazil. In this cross-sectional study, 132 pregnant women monitored by PCF from May to July 2023 were assessed using a self-administered questionnaire for socioeconomic data, the two-item Triage for Food Insecurity (TRIA) instrument for FI risk, the Scale of Parental Beliefs and Early Childhood Care Practices, and the Beck Depression Inventory-II for depressive symptoms. Most participants were multiparous (87.9%), had low income (under 200 USD/month; 80.8%), presented depressive symptoms (67.4%) and were at risk of FI (81.8%). About half demonstrated adequate parental practices (50.8%) and received four home visits per month during pregnancy (54.5%). Women who received four PCF home visits had a lower prevalence of depressive symptoms compared to those with fewer visits (PR 0.76, 95% CI 0.59-0.98). No significant association was found between FI or parental practices and depressive symptoms. These findings suggest that the PCF home-visiting program may strengthen vulnerable families, support social networks, and improve mental health during pregnancy. Additionally, the results of this study highlight the need for targeted interventions aimed at reducing food insecurity and promoting mental health during pregnancy, particularly among socially vulnerable populations. Furthermore, they reinforce the importance of expanding access to home-visiting programs as an effective strategy to improve maternal mental health and well-being, while fostering healthier prenatal environments for both mothers and their children.

Depressive symptoms among adults is associated with decreased food security

OBJECTIVE

We aim to evaluate the association of depressive symptoms, depressive symptoms severity and symptom cluster scores (i.e., cognitive-affective and somatic) with food security (FS). We will also evaluate the interaction effect of sex, income and ethnicity on these associations.

METHODS

Data from the 2005-2018 National Health and Nutrition Examination Survey cycles were used in this study. Participants included survey respondents 20+ years who had completed Depression and Food Security questionnaires. Multivariable logistic regression was used to estimate the associations between depressive symptoms and FS.

RESULTS

A total of 34,128 participants, including 3,021 (7.73%) with depressive symptoms, were included in this study. In both unadjusted and adjusted models, participants with depressive symptoms had lower odds of FS (aOR = 0.347, 95% CI: 0.307,0.391, p<0.001). Moreover, in both unadjusted and adjusted models, for each 1-point increase in cognitive-affective (aOR = 0.850, 95% CI = 0.836,0.864, p <0.001) and somatic symptoms (aOR = 0.847, 95% CI = 0.831,0.863, p <0.001), odds of high FS decreased correspondingly. Our study found no significant interaction effects of sex on depressive symptoms-FS association. Statistically significant interactions of ethnicity and poverty-to-income ratio on depressive symptoms-FS association were observed, revealing higher odds of FS among Non-Hispanic Black and Mexican American groups, and lower odds of FS in Non-Hispanic White and high-income subgroups.

CONCLUSION

Our study demonstrated an association between depressive symptoms and decreased FS. Further research is required to deepen our understanding of the underlying mechanisms and to develop focused interventions.

Food Related Challenges and Mental Health Among U.S. African Migrants: A Narrative Review

The United States' (US) African immigrant (AI) population is growing, yet they are underrepresented in health and nutrition research. This population experiences difficulties finding culturally appropriate foods and navigating the US food environment (FE), is highly food insecure (FI), and vulnerable to mental disorders. This review examined the current evidence for AIs' food and mental health outcomes and connections; and identified gaps in the literature and future research opportunities. A literature search was conducted using Google Scholar, PubMed, CINAHL, MEDLINE, and SCOPUS. Twenty-one studies were identified, reporting high (37-85%) FI rates, poor diet quality, and increased risk of mental disorders among participants. Challenges in the FE, lack of transportation, limited access to ethnic foods, low SES, and language barriers were associated with FI and poor diet quality. Similarly, discrimination, substance use, and immigration status were associated with depression and anxiety. However, studies examining the connection between AI's food experience and mental health are lacking. AIs are at a higher risk for FI, poor diet quality, and mental disorders. Ethnic-specific research to understand the connection between their food and mental health is needed to reduce nutrition and mental health disparities.

Understanding Food Insecurity as a Determinant of Health in Pregnancy Within the United States: An Integrative Review

Background

Food insecurity is a major public health concern in the United States, particularly for pregnant and postpartum individuals. In 2020, ∼13.8 million (10.5%) U.S. households experienced food insecurity. However, the association between food security and pregnancy outcomes in the United States is poorly understood.

Purpose

The purpose of this review was to critically appraise the state of the evidence related to food insecurity as a determinant of health within the context of pregnancy in the United States. We also explored the relationship between food insecurity and pregnancy outcomes.

Methods

PubMed, CINAHL, Web of Science, and Food and Nutrition Science databases were used. The inclusion criteria were peer-reviewed studies about food (in)security, position articles from professional organizations, and policy articles about pregnancy outcomes and breastfeeding practices. Studies conducted outside of the United States and those without an adequate definition of food (in)security were excluded. Neonatal health outcomes were also excluded. Included articles were critically appraised with the STROBE and Critical Appraisal Skills Program checklists.

Results

Nineteen studies met the inclusion criteria. Inconsistencies exist in defining and measuring household food (in)security. Pregnant and postpartum people experienced several adverse physiological and psychological outcomes that impact pregnancy compared with those who do not. Intersections between neighborhood conditions and other economic hardships were identified. Findings regarding the impact of food insecurity on breastfeeding behaviors were mixed, but generally food insecurity was not associated with poor breastfeeding outcomes in adjusted models.

Conclusion

Inconsistencies in definitions and measures of food security limit definitive conclusions. There is a need for standardizing definitions and measures of food insecurity, as well as a heightened awareness and policy change to alleviate experiences of food insecurity.

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.

Household food insecurity is associated with obesogenic health behaviours among a low-income cohort of pregnant women in Boston, MA

OBJECTIVE

To examine associations of household food insecurity with health and obesogenic behaviours among pregnant women enrolled in an obesity prevention programme in the greater Boston area.

DESIGN

Cross-sectional evaluation. Data were collected from structured questionnaires that included a validated two-item screener to assess household food insecurity. We used separate multivariable linear and logistic regression models to quantify the association between household food insecurity and maternal health behaviours (daily consumption of fruits and vegetables, sugar-sweetened beverages and fast food, physical activity, screen time, and sleep), mental health outcomes (depression and stress), hyperglycaemia status and gestational weight gain.

SETTING

Three community health centres that primarily serve low-income and racial/ethnic minority patients in Revere, Chelsea and Dorchester, Massachusetts.

PARTICIPANTS

Totally, 858 pregnant women participating in the First 1,000 Days program, a quasi-experimental trial.

RESULTS

Approximately 21 % of women reported household food insecurity. In adjusted analysis, household food insecurity was associated with low fruit and vegetable intake (β = -0·31 daily servings; 95 % CI -0·52, -0·10), more screen time (β = 0·32 daily hours; 95 % CI 0·04, 0·61), less sleep (β = -0·32 daily hours; 95 % CI -0·63, -0·01), and greater odds of current (adjusted odds ratio (AOR) 4·42; 95 % CI 2·33, 8·35) or past depression (AOR 3·01; 95 % CI 2·08, 4·35), and high stress (AOR 2·91; 95 % CI 1·98, 4·28).

CONCLUSIONS

In our sample of mostly low-income, racial/ethnic minority pregnant women, household food insecurity was associated with mental health and behaviours known to increase the likelihood of obesity.

Racial/Ethnic Differences in the Association Between Food Security and Depressive Symptoms Among Adult Foreign-Born Immigrants in the US: A Cross-Sectional Study

Foreign-born immigrants are at greater risks of both food insecurity and depressive symptoms, while the association between the two has yet to be elucidated. Our sample includes 6,857 adults aged 20 years and older from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2016. Multivariable logistic regression was used to examine whether the association between food security and depressive symptoms varies across race/ethnicity among US foreign-born immigrants. The prevalence of depressive symptoms was 9.6% and 15.7% for low food security (LFS) and very low food security (VLFS). The adjust odds ratios (aORs) of depressive symptoms among Mexican American and Other Hispanic immigrants with VLFS were 2.66 (95% Confidence interval [CI]: 1.61, 4.38) and 2.05 (95% CI: 1.08, 3.86) as compared to those with full food security (FFS). Race/ethnicity may modify the association between food security and depressive symptoms among US foreign-born immigrants and a dose-response relationship was indicated among Hispanic and Other Race immigrants.

The relationship between diet/nutrition and the mental health of immigrants in Western societies through a holistic bio-psycho-socio-cultural lens: A scoping review

Epidemiological evidence suggests that diet and nutrition not only impact individuals' physical health but also shape their mental health (MH). The nutrition/diet-MH relationship may be critical among immigrants due to socioeconomic and sociocultural factors. Despite the complex nutrition/diet-MH relationship, most scholarship in this area employs a biomedical perspective. This scoping review of 63 studies deployed a holistic bio-psycho-socio-cultural framework to examine the relationship between diet/nutrition and immigrants' MH. Five automated databases (Embase, PubMed, Medline, PsycINFO and Anthropology Plus) were systematically searched for relevant articles from Western countries. A bio-psycho-socio-cultural conceptual model guided the analysis of the multi-faceted diet/nutrition-MH relationship. Consumption of fruit/vegetables, unsaturated fats, vitamin D-rich foods and whole grains was significantly positively related to MH. Reported pathways included enhanced self-esteem and ability to stay physically active. Energy-dense food consumption emanating from unhealthful dietary acculturation to the Western lifestyle was associated with poor MH through various mechanisms, including exhaustion and worry about developing non-communicable diseases. Food insecurity and related hunger were significantly positively associated with depression and anxiety among immigrants through different pathways, including family conflicts, homesickness, social exclusion, feelings of shame/stigma, and helplessness related to not affording nutritious foods that meet one's cultural dietary requirements. Ethnic food consumption appeared to mitigate MH issues and enhance immigrants' well-being. A bio-psycho-socio-cultural-informed model is needed to gain an in-depth and encompassing understanding of immigrant MH as it relates to diet/nutrition. The first iteration of such a model is presented in this review alongside an illustration of how it may be used to strengthen an analysis and understanding of the multi-faceted diet/nutrition-MH relationship amongst immigrants and inform public health professionals and dieticians/practitioners.

Disordered eating during pregnancy among individuals participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)

BACKGROUND

Food insecurity is associated with adverse psychosocial and health consequences in pregnancy. In non-pregnant populations, evidence suggests that food insecurity is linked to eating pathology, independent of depression or anxiety. Food assistance programs intended to reduce food insecurity, such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), may unintentionally contribute to eating pathology through a "feast-or-famine" cycle (i.e., cyclical periods of food deprivation and food access over the benefit month). Thus, the present study examined associations between WIC participation and disordered eating in pregnancy, covarying for depressive symptoms.

METHODS

The present study is a secondary analysis of the Pittsburgh Girls Study (PGS), a 21-year prospective longitudinal study that over-sampled households in low resourced neighborhoods. The present analysis included a subset of pregnant PGS participants (N = 210; 13-25 years of age) who reported on WIC participation, and disordered eating and depressive symptoms on validated measures.

RESULTS

Negative binomial regression models covarying for participant's age at conception and gestational age at assessment found that WIC participation was associated with higher scores on overall eating pathology as well as dieting and oral control subscales, but not bulimic or food preoccupation subscales, or a binge-eating item. Patterns of findings did not change when depressive symptom severity was included in models.

DISCUSSION

WIC participation was associated with eating pathology during pregnancy. Future research should clarify directional relationships among food insecurity, food assistance, and eating behavior in pregnancy to promote health equity.

COVID-19 experiences of small-scale fishing households: The case of Lake Victoria, Kenya

Introduction

The impact of COVID-19 on small-scale fishing communities is of great concern given the importance of aquatic foods in trade, nutrition and livelihoods. Using a case study of Lake Victoria, augmented by published literature, we examine the socioeconomic dynamics and severity of COVID-19 impacts on Kenyan fishing communities.

Methods

A household level questionnaire was administered through phone interviews on a monthly basis from June 2020 to May 2021, including a focus group discussion in July 2021.

Results

We find that multifold fear of COVID-19 infection and control measures were present and varied across case rates and stringency of control measures. Fishers and traders reported being affected by disease control measures that limited market access and their ability to fish overnight. In spite of these worries, and contrary to what has been reported in the published literature regarding impacts observed in the early months of the pandemic, we see stable participation in fishing and fish trading over time despite the pandemic. Food insecurity was high before and during the COVID-19 pandemic, but did not substantially shift with the pandemic.

Conclusion

Our findings suggest that Kenyan fishing and fish trading households adopted diverse strategies to cope and balance generating income to provide for their families and staying safe. Our results underscore the need to understand ways in which acute pandemic impacts evolve over time given that effects are likely heterogeneous across small-scale fishing communities.

Association of community-level food insecurity and glycemic control among pregnant individuals with pregestational diabetes

AIM

To evaluate whether pregnant individuals with pregestational diabetes who live in a food-insecure community have worse glycemic control compared to those who do not live in a food-insecure community.

METHODS

A retrospective analysis of pregnant individuals with pregestational diabetes enrolled in a multidisciplinary prenatal and diabetes care program. The exposure was community-level food insecurity per the Food Access Research Atlas. The outcomes were hemoglobin A1c (A1c) < 6.0 % in early and late pregnancy, and an absolute decrease in A1c ≥ 2.0 % and mean change in A1c across pregnancy.

RESULTS

Among 418 assessed pregnant individuals with pregestational diabetes, those living in a food-insecure community were less likely to have an A1c < 6.0 % in early pregnancy compared to those living in a community without food insecurity [16 % vs. 30 %; adjusted risk ratio (aRR): 0.55; 95 % CI: 0.33-0.92]. Individuals living in a food-insecure community were more likely to achieve a decrease in A1c ≥ 2.0 % [35 % vs. 21 %; aRR: 1.55; 95 % CI: 1.06-2.28] and a larger mean decrease in A1c across pregnancy [mean: 1.46 vs. 1.00; adjusted beta: 0.47; 95 % CI: 0.06-0.87)].

CONCLUSIONS

Pregnant individuals with pregestational diabetes who lived in a food-insecure community were less likely to enter pregnancy with glycemic control, but were more likely to have a reduction in A1c and achieve similar A1c status compared to those who lived in a community without food insecurity. Whether interventions that address food insecurity improve glycemic control and consequent perinatal outcomes remains to be studied.

Socio-demographic and geographic disparities of population-level food insecurity during the COVID-19 pandemic in Thailand

Introduction

This study investigated the prevalence of food insecurity, and the association between socio-demographic and geographic factors and food insecurity in Thailand during the COVID-19 pandemic.

Methods

The study extracted data on 5,066 persons age 15 years or older from a nationally-representative sample survey of Thai households, conducted during June-December 2021. The respondents were asked about food insecurity, socio-demographic characteristics, debt, and role of the primary household food provider. Binary logistic regression analysis was used to investigate the association between the variables and food insecurity.

Results

Of the total sample, 28.6% had food insecurity. The highest probability of having food insecurity (p < 0.001) was observed in persons age 15-29 years, with no formal education, and in the lowest quartile of income. The highest probability of having food insecurity was found among respondents residing in the northeast, which is the poorest and with the least development status among geographic regions in Thailand. Respondents who reported having onerous personal debt and being the main household food provider were 1.4 and 2.3 times as likely to have food insecurity as those with no debt and not being the main food provider, respectively (p < 0.001).

Conclusion

This suggests that government attention is required in developing policies and strategies to improve food security through addressing the socio-economic determinants, and buffer the negative impact of a national crisis on diets. Investment to improve household income and raise the educational profile of the population is needed. Addressing the regional disparities in food security requires area-specific measures which target the most vulnerable population groups.

WIC Staff Views and Perceptions on the Relationship between Food Insecurity and Perinatal Depression

Food insecurity and perinatal depression are significant public health concerns for perinatal services, however descriptive research examining their association is limited. The purpose of this study was to examine the views and perspectives of staff from the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) program on the relationship between food insecurity and perinatal depression among their WIC clients. Four, semi-structured focus groups with WIC staff (n = 24) were conducted across four diverse nonmetropolitan public health districts in Midwestern counties in the United States. WIC staff included social workers, nurses, nutritionists and ancillary staff. All interviews were audio-recorded, transcribed, and verified, and data were organized using NVivo 11.4.2. Thematic networking analysis was employed as the qualitative analysis to identify organizing themes. Three themes emerged including (1) depression experienced by clients; (2) food insecurity experienced by clients; and (3) barriers preventing clients from accessing services for themselves and their children. Research on food insecurity and perinatal depression is sparse, with fewer studies having included health staff of low-income women. Our findings suggest that the association between food insecurity and mental health needs among WIC clients is a significant public health issue to which policy change and interventions are required.

Association of Food Insecurity with Mental Health Outcomes in Parents and Children

BACKGROUND

Food insecurity affects 13.7 million US households and is linked to poor mental health. Families shield children from food insecurity by sacrificing their nutritional needs, suggesting parents and children experience food insecurity differentially.

OBJECTIVE

To identify the associations of food insecurity and mental health outcomes in parents and children DATA SOURCES: PubMed, Embase, Web of Science, and PsycInfo STUDY ELIGIBILITY CRITERIA: We included original research published in English from January 1990 to June 2020 that examined associations between food insecurity and mental health in children or parents/guardians in the United States.

STUDY APPRAISAL AND SYNTHESIS METHODS

Two reviewers screened studies for inclusion. Data extraction was completed by one reviewer and checked by a second. Bias and confounding were assessed using the Agency for Healthcare Research and Quality RTI Item Bank. Studies were synthesized qualitatively, grouped by mental health outcome, and patterns were assessed. Meta-analyses were not performed due to high variability between studies.

RESULTS

We included 108 studies, assessing 250,553 parents and 203,822 children in total. Most studies showed a significant association between food insecurity and parental depression, anxiety, and stress, and between food insecurity and child depression, externalizing/internalizing behaviors, and hyperactivity.

LIMITATIONS

Most studies were cross-sectional and many were medium- or high-risk for bias or confounding.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

Food insecurity is significantly associated with various mental health outcomes in both parents and children. The rising prevalence of food insecurity and mental health problems make it imperative that effective public health and policy interventions address both problems.

The Ukraine–Russia War Is Deepening Food Insecurity, Unhealthy Dietary Patterns and the Lack of Dietary Diversity in Lebanon: Prevalence, Correlates and Findings from a National Cross-Sectional Study

Background: Due to Russia and Ukraine’s key roles in supplying cereals and oilseeds, the Russia–Ukraine war intensifies the current food availability and price challenges in Lebanon, which is a major wheat importer. Given these constraints, we conducted this study to assess the prevalence and correlates of food insecurity, low dietary diversity (DD), unhealthy dietary patterns, and the shifts in households’ food-related habits in response to the Russia–Ukraine war among a representative sample of Lebanese household’s members aged 18 years and above (N = 914). Methods: Data were collected between June and July 2022 using self-administered questionnaires; Results: Findings showed that nearly half of the households consume an undiversified diet (46%), and 55.3% ate fewer than two meals per day. The prevalence of food insecurity among Lebanese households was 74%, with one in every four households being severely food insecure. In addition, the majority of households’ members went out shopping and purchased food less than the pre-war period (68.7% and 70.3%, respectively). Furthermore, almost 68.3% of households’ members highlighted price increases for cereal products, which were the least available and most stocked items. Findings obtained through binary logistic regression also showed that food insecurity was two times higher among households with low monthly income, 35% higher among females, and three times higher among married participants; Conclusions: The impact of the Russia–Ukraine conflict on food security in Lebanon requires a systems-thinking approach as well as international effort to understand the challenges and find solutions to minimize the war’s negative effects.

How demographics and concerns about the Trump administration relate to prenatal mental health among Latina women

RATIONALE

The 2016 U.S. presidential election and its aftermath involved political rhetoric and policies that especially targeted women, Latinos, and immigrants. It is possible that concerns about the political environment could affect mental health of individuals in targeted groups.

OBJECTIVE

In a cohort of 148 pregnant Latina women, this study investigated how demographics and political concerns related to each other and to maternal anxiety, depression, and perceived stress, which have been associated with adverse birth and child development outcomes.

METHODS

In this cross-sectional, self-report study, participants in Southern California completed a one-time questionnaire from January 2017 to May 2018.

RESULTS

The highest rates of endorsement were for concerns regarding President Trump's racism, attitude towards women, and deportation risk for family or friends. From several demographic variables, the only significant predictor of state anxiety was expectant parents' birthplaces. From several political concerns variables, the only significant predictor of state anxiety was President Trump's attitude towards women or women's rights. There were no significant effects on other mental health outcomes.

CONCLUSIONS

Results suggest that birthplace and women's issues may be particularly salient anxiety risk factors for Latina pregnant women in this context. Because of the cross-sectional study design, it is possible that, conversely, pregnant women with high anxiety levels are particularly sensitive to the issue of birthplace or women's rights. Results imply that the political climate and events in the U.S. could have deleterious consequences that may cascade across generations of Latino Americans via effects on pregnant women.

Food Insecurity and Depression among US Adults: NHANES 2005-2016

A growing body of evidence suggests that food insecurity is associated with adverse mental health outcomes such as depression and anxiety. In this study, the relationship between food insecurity and depression was examined using data from the 2005−2016 National Health and Nutrition Examination Survey (NHANES). Food insecurity was assessed with the 18-item United States Food Security Survey Module with zero affirmative responses indicating high food security, 1 or 2 affirmative responses indicating marginal food security, and ≥3 affirmative responses indicating food insecurity. Depression was assessed with the Patient Health Questionnaire-9 with scores ≥10 indicating depression. Data were analyzed from 28,448 adult participants aged 20 or older. Food insecurity was present in 19.2% of the sample population (n = 5452). Food security status was significantly associated with gender, race, education level, marital status, smoking status, and BMI (Rao-Scott chi-square, p < 0.05). Fully food secure and very low food security adults experienced depression at a rate of 5.1% and 25.8%, respectively (Rao-Scott chi-square, p < 0.0001). Participants with very low food security had a significantly greater odds of depression than food secure adults, OR = 3.50 (95% CI: 2.98, 4.12). These findings suggest that food insecurity is a significant risk factors for depression in US adults over 20 years of age. To address this issue in our citizenry, police initiatives and public health interventions addressing both food access and mental health should be prioritized.

Food Insecurity in the Food Allergic Population: A Work Group Report of the AAAAI Adverse Reactions to Foods Committee

Food allergies affect 32 million Americans. Restricted diets due to food allergies can be difficult to maintain especially when the household is food insecure. Food insecurity is defined as the inability to acquire food for household members due to insufficient money or resources for food. The COVID-19 pandemic has caused many people to face food insecurity for the first time with Latinx, Native American, and Black communities disproportionately affected. Because of the increase in food insecurity, this work group developed a survey regarding food insecurity screening. This survey was sent out to a random sample of American Academy of Allergy Asthma & Immunology members to assess food insecurity knowledge and practices. The majority of survey participants did not routinely screen their patients for food insecurity. The biggest barrier identified to screening was lack of knowledge of how to perform a screen and resources available when a patient screened positive. This work group report provides guidance on how to implement and perform a food insecurity screen, including federal resources and assistance programs.

Food and nutritional insecurity is associated with depressive symptoms mediated by NR3C1 gene promoter 1F methylation

The aim of this study was to investigate socioeconomic stressors predictive of depressive symptoms and possible epigenetic changes in the glucocorticoid receptor - NR3C1-1F - an encoding gene involved in depressive symptoms. A total of 321 adult volunteers from southeastern Brazil were recruited to evaluate depressive symptoms, socio-demographic and economic factors, including food and nutritional security (FNS) or insecurity (FNiS) status, and NR3C1-1F region methylation by pyrosequencing. Depressive symptom determinants were investigated using a Poisson regression model with robust variance. Mann-Whitney tests and structural mediation equation models were used to evaluate the relationship between NR3C1 DNA methylation, FNiS, and depressive symptoms. Multivariate Poisson regression with robust variance adjusted for sex and FNiS and NR3C1-1F region methylation predicted risk factors for depressive symptoms. Mediation analysis revealed that NR3C1-1F region methylation mediated the relationship between FNiS exposure and depressive symptoms as an outcome, and depressive volunteers and FNiS individuals exhibited a significant increase in NR3C1 methylation when compared to healthy individuals and FNS volunteers, respectively. Therefore, we suggest that stress caused by FNiS may lead to depressive symptoms and that NR3C1-1F DNA methylation can act as a mediator of both FNiS and depressive symptoms.

Integrated Nutrition and Culinary Education in Response to Food Insecurity in a Public University

Food insecurity is an emerging issue for college students. A nutrition course with an integrated teaching kitchen was developed to address this issue at a large public university. We aimed to determine changes in food insecurity and stress among students who took the course. The course consisted of weekly lectures followed by teaching kitchen lab sessions to teach basic nutrition and culinary concepts and expose students to hands-on skill development cooking experiences. Using a pre-post design, enrolled students completed an anonymous online survey at the beginning and the end of the semester. Food security was assessed with the USDA Six-Item Food Security Module; stress was measured using the Perceived Stress Scale (PSS). Pre- and post-data were linked for 171 participants. Paired data statistical analysis comparing the post- vs. the pre-test showed an increase in food security and a decrease in very low security rates (from 48% to 70%, and from 23% to 6%, respectively; p < 0.0001), and a decrease on the average PSS score, indicating lower stress (from (Mean ± SD) 19.7 ± 5.9 to 18.1 ± 6.0; p = 0.0001). A nutrition and culinary course may be an effective response to food insecurity and could potentially improve students’ wellbeing.

Food insecurity in pregnant women is associated with social determinants and nutritional outcomes: a systematic review and meta-analysis

The association between FI, social determinants, and nutritional outcomes for pregnant women are analyzed. A systematic review was conducted through a search of articles in five electronic databases. Social determinants (race, education, participation in social programs) and nutritional status (pre-gestational BMI, gestational weight gain, anemia) were analyzed in relation to the FI situation. For each article, the frequency of food insecurity was collected in order to calculate the summary measure, prevalence ratio (PR). 26 articles were selected. An elevated occurrence of FI was associated with black pregnant women (PR: 1.83, 95% CI 1.08-3.10), participation in social protection programs (PR = 1.43, 1.02-2.01), and with low education levels on the part of pregnant women (PR = 2.73, 1.68-4.43). FI increased the chances of being overweight (PR = 1.57, 95% CI = 1.29-1.91) and obese (PR = 1.47, 95% CI = 1.15-1.87) in pregnant women, as well as excessive weight gain (PR = 1.42, 95% CI = 1.10-1.82) and inadequate weight gain (PR = 1.47; 95% CI = 1.09-1.97) during pregnancy. Anemia was not associated with FI. Social inequities are associated with food and nutritional insecurity in pregnant women.

Prevalence and Covariates of Food Insecurity Across the First 1000 Days Among Women of Mixed HIV Status in Western Kenya: A Longitudinal Perspective

BACKGROUND

Food insecurity (FI) is common globally and can have lifelong consequences. However, few studies have longitudinally examined how FI varies across gestation and the postpartum period ("the first 1000 days"); none have explored this in sub-Saharan Africa or in the context of HIV.

OBJECTIVE

To assess the prevalence and covariates of FI in the first 1000 days among Kenyan women.

METHODS

All pregnant women attending 7 clinics in western Kenya (n = 1247) were screened for HIV and FI (Individual Food Insecurity Access Scale) between September 2014 and June 2015. A subset of women (n = 371) was recruited into an observational cohort study and surveyed 11 times through 2 years postpartum (NCT02974972, NCT02979418). Data on FI, sociodemographics, and health were repeatedly collected. Severe FI was modeled using multilevel, mixed-effects logistic regressions (n = 346).

RESULTS

Of the 1247 pregnant women screened, 76.5% were severely food insecure in the prior month. Further, the prevalence of severe FI was higher among women living with HIV than those without (82.6% vs 74.6%, P < .05). In the cohort, the odds of being severely food insecure decreased monotonically after delivery. Each point higher on the Center for Epidemiologic Studies-Depression scale was associated with 1.08 times greater odds of being severely food insecure (95% CI: 1.05-1.10); each point higher on the Duke/UNC Functional Social Support Scale was associated with 0.97 lower odds of severe FI (95% CI: 0.94-0.99).

CONCLUSIONS

Severe FI is prevalent during the first 1000 days in western Kenya. Services to mitigate the far-reaching consequences of this modifiable risk should be considered.

Pregnant and hungry: addressing food insecurity in pregnant women during the COVID-19 pandemic in the United States

Food insecurity is a major social determinant of health affecting more than 10% of Americans. Social determinants of health are increasingly recognized as a driving force of health inequities. It is well established that food insecurity leads to adverse health outcomes outside of pregnancy, such as obesity, hypertension, diabetes mellitus, and mental health problems. However, limited data exist about the impact of food insecurity during pregnancy on maternal and neonatal outcomes. Food insecurity and other social determinants of health are rarely addressed as part of routine obstetrical care. The COVID-19 pandemic has only exacerbated the crisis of food insecurity across the country, disproportionally affecting women and racial and ethnic minorities. Women's health providers should implement universal screening for maternal food insecurity and offer resources to women struggling to feed themselves and their families. Reducing maternal health inequities in the United States involves recognizing and addressing food insecurity, along with other social determinants of health, and advocating for public policies that support and protect all women's right to healthy food during pregnancy.

Disentangling food insecurity and maternal depression: which comes first?

OBJECTIVE

To determine the temporal directionality of the association between food insecurity and maternal depression.

DESIGN

Food insecurity was measured at two time points using the eighteen-item USDA Food Security Scale. Maternal depression was measured at two time points using the fifteen-item Composite International Diagnostic Interview-Short Form. Two structural equation models were utilised to evaluate the impact of food insecurity on maternal depression (model 1) and the impact of maternal depression on food insecurity (model 2). Both models controlled for socio-demographic and parenting characteristics and child behaviour problems, along with prior measures of the dependent variable and concurrent measures of the independent variable.

SETTING

Fragile Families and Child Wellbeing (FFCW) study, twenty cities across the USA.

PARTICIPANTS

4897 mothers who participated in two waves of the FFCW study.

RESULTS

On average, 17 % (time 1) and 15 % (time 2) of mothers experienced food insecurity and 21 % (time 1) and 17 % (time 2) of mothers experienced depression over time. Maternal depression at time 1 was associated with 53 % increased odds (OR = 1·53; B = 0·43; P < 0·001) of food insecurity at time 2, controlling for time 1 food insecurity, concurrent depression and covariates. Food insecurity at time 1 was associated with 36 % increased odds (OR = 1·36; B = 0·31; P < 0·001) of maternal depression at time 2, controlling for time 1 depression, concurrent food insecurity and covariates.

CONCLUSIONS

We found a bidirectional relationship between food insecurity and maternal depression. A holistic approach that combines food assistance and mental health services may be an efficacious approach to reducing both depressive symptoms and food insecurity among low-income mothers.

The Association Between Food-Away-From-Home Frequency and a Higher BMI Varies by Food Security Status in US Adults

BACKGROUND

For decades, Americans have increasingly relied on food away from home (FAFH) despite its association with negative health outcomes. Little is known about FAFH frequency and expenditures of adults with lower food security (FS) and their association with health outcomes, such as BMI.

OBJECTIVES

We evaluated patterns of adults' FAFH purchases by FS status and other demographic characteristics, and examined the association between FAFH frequency and BMI in adults of varying levels of FS.

METHODS

This cross-sectional study used data from the Consumer Behavior Survey, Food Security Survey, and anthropometric measurements to assess FAFH frequency and expenditures, FS, and calculated BMI of adults (≥18 y) who participated in the NHANES 2007-2014 (n = 20,733). We used multinomial logistic regression to examine the association between FAFH frequency quartiles (quartile 1: 0 n/wk; quartile 2: 1-2 n/wk; quartile 3: 3-4 n/wk; quartile 4: ≥5 n/wk) and BMI by FS category.

RESULTS

Although FAFH frequency was similar across FS levels, adults with high FS spent more dollars (${\$}$213.60) and a greater proportion (29.4%) of their food budget on FAFH compared with adults with marginal, low, and very low FS (${\$}$133.00, ${\$}$116.20, ${\$}$103.30 and 21.4%, 19.7%, 20.0%, respectively). Obesity prevalence was highest in adults with low FS (42.9%) and very low FS (41.5%), and lowest in adults with high FS (33.7%). FAFH frequency and BMI were positively associated in adults with high (P < 0.001), marginal (P = 0.025), and low (P = 0.024) FS, but not in adults with very low FS (P = 0.589).

CONCLUSIONS

FAFH is frequent in adults regardless of FS status. The positive association between FAFH and BMI is the strongest in adults with high FS, the group with the lowest prevalence of obesity. Conversely, BMI was not associated with FAFH in adults with very low FS, despite their higher prevalence of obesity.

Household food insecurity associations with pregnancy hypertension, diabetes mellitus and infant birth anthropometric measures: a cross-sectional study of Iranian mothers

Objective: The purpose of this study was to determine the associations between food insecurity on pregnancy and its outcomes.Materials and methods: This cross-sectional study was carried out on 700 Iranian mothers. Household socioeconomic status, prenatal information and household food security status were assessed using questionnaires. Data analysis was applied by SPSS version 22.Results: The results of the study showed a significant association between food insecurity with gestational diabetes mellitus. The results also showed a significant association between birth weight, and height with pregnancy-induced hypertension.Conclusion: food insecure women should be recognized, and receive appropriate training and assistance.

Household food insecurity is associated with depressive symptoms in the Canadian adult population

BACKGROUND

It is essential to identify factors associated with depression as it is a highly prevalent and disabling mental disorder. The aim of this study was to examine the association between depressive symptoms and household food security status among the Canadian adult population.

METHODS

This is a cross-sectional study of the adult population in the five provinces and one territory (Northwest Territories) of Canada using data from the 2015-2016 Canadian Community Health Survey-Annual Component (n=19,118). Depressive symptoms were assessed using the 9-item Patient Health Questionnaire. Household food insecurity was measured using the Household Food Security Survey Module. A weighted logistic regression analysis with robust variance estimation technique was performed.

RESULTS

Approximately 22% of the Canadian adult population reported mild-to-severe depressive symptoms, and 8.3% were from households classified as food insecure. Household food insecurity remained a predictor of mild-to-severe depressive symptoms after adjustment for other known risk factors (OR_ajd: 2.87, 95% CI: 2.33-3.55, p<0.001). In the multivariable model, significant associations were also found with multimorbidity, lower household income, a history of illicit drug use, being a current smoker, being a widowed/divorced/separated, obesity, and being a non-drinker. Significant interactions also emerged between employment status and age (p=0.03), employment status and gender (p<0.001), and physical activity level and gender (p<0.001).

LIMITATIONS

The cross-sectional nature of the study does not allow inferring causality.

CONCLUSIONS

Household food insecurity is associated with depressive symptoms in Canadian adults. Additional longitudinal research is required to further elucidate the nature of this relationship.

Association Between Receipt of Unemployment Insurance and Food Insecurity Among People Who Lost Employment During the COVID-19 Pandemic in the United States

Importance

More than 50 million US residents have lost work during the coronavirus disease 2019 (COVID-19) pandemic, and food insecurity has increased.

Objective

To evaluate the association between receipt of unemployment insurance, including a $600/wk federal supplement between April and July, and food insecurity among people who lost their jobs during the COVID-19 pandemic.

Design, Setting, and Participants

This cohort study used difference-in-differences analysis of longitudinal data from a nationally representative sample of US adults residing in low- and middle-income households (ie, <$75 000 annual income) who lost work during the COVID-19 pandemic. Data were from 15 waves of the Understanding Coronavirus in America study (conducted April 1 to November 11, 2020).

Exposure

Receipt of unemployment insurance benefits.

Main Outcomes and Measures

Food insecurity and eating less due to financial constraints, assessed every 2 weeks by self-report.

Results

Of 2319 adults living in households earning less than $75 000 annually and employed in February 2020, 1119 (48.3%) experienced unemployment during the COVID-19 pandemic and made up our main sample (588 [53.6%] White individuals; mean [SD] age 45 [15] years; 732 [65.4%] women). Of those who lost employment, 415 (37.1%) reported food insecurity and 437 (39.1%) reported eating less due to financial constraints in 1 or more waves of the study. Among people who lost work, receipt of unemployment insurance was associated with a 4.3 (95% CI, 1.8-6.9) percentage point decrease in food insecurity (a 35.0% relative reduction) and a 5.7 (95% CI, 3.0-8.4) percentage point decrease in eating less due to financial constraints (a 47.8% relative reduction). Decreases in food insecurity were larger with the $600/wk supplement and for individuals who were receiving larger amounts of unemployment insurance.

Conclusions and Relevance

In this US national cohort study, receiving unemployment insurance was associated with large reductions in food insecurity among people who lost employment during the COVID-19 pandemic. The $600/wk federal supplement and larger amounts of unemployment insurance were associated with larger reductions in food insecurity.

Disparities in Cardiovascular Disease Outcomes Among Pregnant and Post-Partum Women

Background

The incidence of cardiovascular disease among pregnant women is rising in the United States. Data on racial disparities for the major cardiovascular events during pregnancy are limited.

Methods and Results

Pregnant and post‐partum women hospitalized from January 2007 to December 2017 were identified from the Nationwide Inpatient Sample. The outcomes of interest included: in‐hospital mortality, myocardial infarction, stroke, pulmonary embolism, and peripartum cardiomyopathy. Multivariate regression analysis was used to assess the independent association between race and in‐hospital outcomes. Among 46 700 637 pregnancy‐related hospitalizations, 21 663 575 (46.4%) were White, 6 302 089 (13.5%) were Black, and 8 914 065 (19.1%) were Hispanic. The trends of mortality and stroke declined significantly in Black women, but however, were mostly unchanged among White women. The incidence of mortality and cardiovascular morbidity was highest among Black women followed by White women, then Hispanic women. The majority of Blacks (62.3%) were insured by Medicaid while the majority of White patients had private insurance (61.9%). Most of Black women were below‐median income (71.2%) while over half of the White patients were above the median income (52.7%). Compared with White women, Black women had the highest mortality with adjusted odds ratio (aOR) of 1.45, 95% CI (1.21–1.73); myocardial infarction with aOR of 1.23, 95% CI (1.06–1.42); stroke with aOR of 1.57, 95% CI (1.41–1.74); pulmonary embolism with aOR of 1.42, 95% CI (1.30–1.56); and peripartum cardiomyopathy with aOR of 1.71, 95 % CI (1.66–1.76).

Conclusions

Significant racial disparities exist in major cardiovascular events among pregnant and post‐partum women. Further efforts are needed to minimize these differences.

The association between HIV/AIDS and food insecurity at the US-Mexico border: Experiences of low-income patients in the Rio Grande Valley

US-Mexico border communities are uniquely vulnerable to human immunodeficiency virus (HIV) transmission given the economic and social challenges these communities face. We surveyed low-income, predominantly Latinx residents receiving sexually transmitted infection testing and/or HIV/acquired immune deficiency syndrome (AIDS) care in the lower Rio Grande Valley of southernmost Texas about their experiences of food insecurity. Participants aged 18 years and over took a self-administered survey available in English or Spanish in a clinic waiting room (N = 251). Ordinary least squares regression results suggested that those with a prior HIV/AIDS diagnosis reported a response for food insecurity that was approximately 0.67 points higher than peers without a prior HIV/AIDS diagnosis (coefficient = 0.67; p < 0.05), even when adjusting for sociodemographic characteristics, social support, perceived discrimination, and neighborhood environment. Interaction results between age and HIV status indicated that younger individuals living with HIV/AIDS experienced uniquely higher food insecurity; those who reported a prior HIV/AIDS diagnosis experienced an additional reduction in food insecurity by approximately 0.06 points for each additional year of age (age × HIV/AIDS interaction coefficient = -0.06; p < 0.05). Community programs serving low-income populations should consider screening for and intervening on food insecurity, especially among young adults living with HIV/AIDS.

Food insecurity and depression among low-income adults in the USA: does diet diversity play a role? Findings from the 2013-2014 National Health and Nutrition Examination Survey

OBJECTIVE

Food insecurity is associated with a greater risk of depression among low-income adults in the USA. Members of food-insecure households have lower diet diversity than their food-secure counterparts. This study examined whether diet diversity moderates the association between food insecurity and depression.

DESIGN

Multiple logistic regression was conducted to examine independent associations between food insecurity and depression, between diet diversity and depression, and the moderating effect of diet diversity in the food insecurity-depression link.

SETTING

Cross-sectional data from the National Health and Nutrition Examination Survey (2013-2014).

PARTICIPANTS

2636 low-income adults aged 18 years and older.

RESULTS

There was a positive association between food insecurity and depression among low-income adults. Diet diversity was not associated with depression. Diet diversity had a moderating effect on the association between food insecurity and depression among low-income adults.

CONCLUSIONS

Food insecurity is independently associated with depression among low-income adults in the USA. However, this association differs across levels of diet diversity. Longitudinal studies are needed to confirm the role diet diversity may play in the pathway between food insecurity and depression.

Unemployment insurance and food insecurity among people who lost employment in the wake of COVID-19

Forty million U.S. residents lost their jobs in the first two months of the coronavirus disease 2019 (COVID-19) pandemic. In response, the Federal Government expanded unemployment insurance benefits in both size ($600/week supplement) and scope (to include caregivers and self-employed workers). We assessed the relationship between unemployment insurance and food insecurity among people who lost their jobs during the COVID-19 pandemic in the period when the federal unemployment insurance supplement was in place. We analyzed data from the Understanding Coronavirus in America (UAC) cohort, a longitudinal survey collected by the University of Southern California Center for Economic and Social Research (CESR) every two weeks between April 1 and July 8, 2020. We limited the sample to individuals living in households earning less than $75,000 in February 2020 who lost their jobs during COVID-19. Using difference-in-differences and event study regression models, we evaluated the association between receipt of unemployment insurance and self-reported food insecurity and eating less due to financial constraints. We found that 40.5% of those living in households earning less than $75,000 and employed in February 2020 experienced unemployment during the COVID-19 pandemic. Of those who lost their jobs, 31% reported food insecurity and 33% reported eating less due to financial constraints. Food insecurity peaked in April 2020 and declined over time, but began to increase again among people receiving unemployment insurance during the final wave of the survey ahead of the federal supplement to unemployment insurance ending. Food insecurity and eating less were more common among people who were non-White, lived in lower-income households, younger, and who were sexual or gender minorities. Receipt of unemployment insurance was associated with a 4.4 percentage point (95% CI: −7.8 to −0.9 percentage points) decline in food insecurity (a 30.3% relative decline compared to the average level of food insecurity during the study period). Receipt of unemployment insurance was also associated with a 6.1 percentage point (95% CI: −9.6 to −2.7 percentage point) decline in eating less due to financial constraints (a 42% relative decline). Estimates from event study specifications revealed that reductions in food insecurity and eating less were greatest in the four-week period immediately following receipt of unemployment insurance, with no evidence of differential pre-existing trends in either outcome. We conclude that receiving unemployment insurance benefits during the period when the $600/week federal supplement was in place was associated with large reductions in food insecurity.

Food insecurity, gestational weight gain and gestational diabetes in the National Children’s Study, 2009–2014

Background

Household food insecurity (HFI) and gestational diabetes mellitus (GDM) are both common during pregnancy, yet it is unknown if these two factors are related. We aimed to determine the independent and joint associations between HFI, gestational weight gain (GWG) and GDM among pregnant women in the USA.

Methods

We used data from 592 women in the National Children’s Study, Initial Vanguard Study from 2009 to 2014. HFI was assessed using the Household Food Security Survey Module at the first study visit; GDM was assessed through questionnaires and medical chart review. Logistic regression models were used to investigate the exposures of HFI, GWG and their joint effect on GDM.

Results

Among participants, 20.1% were marginally food secure or food insecure and 7.4% were diagnosed with GDM. The elevated unadjusted association between HFI and GDM was attenuated after adjustment (aOR: 1.12; 95%CI: 0.47, 2.66). There was an elevated risk of GDM associated with inadequate GWG, (aOR: 2.42; 95%CI: 0.97, 6.00), but results were imprecise. There were no statistically significant associations in the joint exposure analysis.

Conclusion

The relationship between HFI and GDM is mostly explained by other covariates, but there is some evidence that inadequate GWG is a possible risk factor for GDM.

Food insecurity as a risk factor for preterm birth: a prospective facility-based cohort study in rural Haiti

INTRODUCTION

Haiti has an estimated neonatal mortality rate of 32/1000 live births, the highest in the Western Hemisphere. Preterm birth and being born small for gestational age (SGA) are major causes of adverse neonatal outcomes worldwide. To reduce preterm birth and infants born SGA, it is important to understand which women are most at risk and how risk varies within countries. There are few studies estimating the prevalence and risk factors for these conditions in Haiti, particularly in rural regions.

METHODS

We conducted a prospective cohort study of pregnant women at a rural tertiary care centre in Haiti from May to December 2017. We collected data during interviews and from the medical record. We built multivariable models to identify risk factors for preterm birth and being born SGA among women who had a facility-based delivery.

RESULTS

1089 pregnant women delivered at the hospital and were included in this analysis. Median gestational age at delivery was 38 weeks (IQR 36-40). In multivariable analyses, risk factors for preterm birth included maternal age <20 years (adjusted OR (AOR) 1.76, 95% CI 1.14 to 2.72) and >34 years (AOR 1.46, 95% CI 1.01 to 2.11) and severe hunger in the household (AOR 1.57, 95% CI 1.09 to 2.26). Risk factors for SGA were age >34 years (AOR 1.76, 95% CI 1.18 to 2.59), twin pregnancy (AOR 3.28, 95% CI 1.20 to 8.95) and first pregnancy (AOR 1.57, 95% CI 1.12 to 2.23). Number of prior abortions was associated with reduced risk for SGA (AOR 0.41, 95% CI 0.17 to 0.97).

CONCLUSIONS

Food insecurity as a risk factor for preterm birth stands out as an important addition to the understanding of the risk of neonatal morbidity and mortality. This association highlights a potentially important intervention target to improve birth outcomes and suggests that food support has an important role to play for pregnant women who are food insecure in low-income settings.

Household Food Insecurity and the Association with Cumulative Biological Risk among Lower-Income Adults: Results from the National Health and Nutrition Examination Surveys 2007-2010

Household food insecurity has been associated with adverse health outcomes; however, the mechanisms underlying these associations are not well-defined. Using data from 5005 adults from the 2007-2010 National Health and Nutrition Examination Surveys (NHANES), we examined associations between household food insecurity and cumulative biological risk, a measure of the body's physiological response to chronic stress. Household food security was assessed using the 18-item Household Food Security Survey Module. Marginal food security refers to 1-2 positive responses, and food insecurity refers to ≥3 positive responses. The cumulative biological risk scores were calculated based on the distributions of ten biomarkers from the cardiovascular, metabolic, and immune systems. Elevated biological risk was defined as a risk score of ≥3. Multivariable regression models were used to examine associations between food security and cumulative biological risk scores, adjusting for sociodemographic characteristics. After multivariable adjustment, food insecurity was associated with a 0.14-unit higher cumulative biological risk score (95% CI 0.05-0.22, p-trend = 0.003) and higher odds of elevated biological risk (OR 1.20, 95% CI 1.05-1.37, p-trend = 0.003). These associations differed by gender. Among women, food insecurity was associated with 0.30-unit higher cumulative biological risk score (95% CI 0.14-0.45, p-trend = 0.0004) and higher odds of elevated biological risk (OR 1.61, 95% CI 1.29-2.00, p-trend < 0.0001). These associations were not observed in men. Women experiencing food insecurity demonstrated elevated levels of biological risk. These findings support the hypothesis that food insecurity may be associated with women's chronic health outcomes through the pathway of chronic stress. Further research is needed to understand why these associations were not observed in men.

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.

TRIAL REGISTRATION

This systematic review was registered on PROSPERO (CRD42018109478).

The Relationship between Household Food Insecurity and Depressive Symptoms among Pregnant Women: A Cross Sectional Study

Objective: There is growing evidence suggesting that household food insecurity (HFI) is associated with adverse outcomes on mental health; however, limited evidence exists for pregnant women. This study was conducted to determine the relationship between HFI and depressive symptoms among a sample of pregnant women. Method : This cross sectional study was performed on 394 pregnant women referring to the health centers located in Qom, Iran, from October 2017 to March 2019. HFI was evaluated using an 18-item US Household Food Security Survey Module. The Beck Depression Inventory-II questionnaire was applied to determine the severity of depressive symptoms. Logistic regression analysis was used to determine the factors associated with elevated depressive symptoms in the study population. Results: The mean (± standard deviation) age of the study population was 28.59 ± 7.28 years. Almost 48% of participants were food insecure, and 37% experienced elevated levels of depressive symptoms during pregnancy. The prevalence of elevated depressive symptoms was significantly higher in food-insecure (P < 0.001) and unemployed (P = 0.02) women, while it was significantly lower in women with higher education levels (P < 0.001). In the adjusted model, it was revealed that HFI was significantly associated with the higher likelihood of having elevated depressive symptoms (OR = 3.31, 95% CI = 2.07, 5.29), while the higher level of education was negatively associated with the levels of depressive symptoms (OR = 0.40, 95% CI = 0.20, 0.79). Conclusion: HFI was positively associated with the severity of depressive symptoms in a sample of pregnant women. Further studies are needed to confirm this finding. Meanwhile, routine screening of HFI for all pregnant women in the community health centers is recommended.

Household food insecurity and antepartum depression in the National Children's Study

PURPOSE

The purpose of this study was to determine the association between household food insecurity (HFI) and elevated antepartum depressive symptoms (EADS) in the National Children's Study, 2009-2014, as well as standardize our results to the U.S. pregnant population.

METHODS

HFI was collected at participants' baseline visits using the U.S. Household Food Security Survey Module; antepartum depression symptoms were collected twice during pregnancy using the Center for Epidemiologic Study Depression scale. Generalized estimating equations for binary outcomes were used to estimate the association between HFI and EADS. Inverse probability weighting was used to generalize the effect to the U.S. population using the National Health and Nutrition Examination Survey.

RESULTS

Among 746 participants, 20.6% were food insecure. Women who were food insecure were 3.39 times (95% confidence interval: 1.73, 6.62) as likely to report EADS compared with women who were food secure. This estimate was marginally strengthened in a weighted analysis (odds ratio: 3.68; 95% confidence interval: 1.43, 9.43).

CONCLUSIONS

This study suggests that women who are food insecure are at a greater risk of EADS, and HFI should be evaluated when assessing antepartum depression.

Understanding the Psychological Distress of Food Insecurity: A Qualitative Study of Children's Experiences and Related Coping Strategies

BACKGROUND

Food insecurity, a condition of inadequate household food availability, affects 15.7% of US households with children. Food insecurity is generally believed to affect the quantity and quality of food consumed. However, an understudied but important aspect of the experience of food insecurity is psychological distress.

OBJECTIVE

To critically explore the psychological distress associated with children's food insecurity using children's own reports of their experiences.

DESIGN

In-depth qualitative interviews conducted with children to better understand the psychological distress associated with food insecurity.

PARTICIPANTS/SETTING

Sixty children (aged 7 to 14 years) were recruited from the San Francisco Bay Area. Children were eligible in the case that they spoke English fluently and their parent reported any experience of household food insecurity during the past year.

RESULTS

Children discussed six themes related to the psychological distress associated with food insecurity: worrying about not having enough food, worrying about their parents' well-being, anger and frustration about not having enough food, embarrassment about their family's food situation, strain on the family's dynamics due to food insecurity, and sadness over not having enough food. After describing their experiences, children described strategies they employed to tolerate or cope with food insecurity, including distracting from or using their imagination to cope with food insecurity, increasing tolerance of their family's food situation, and appreciating their parents for providing food and resources.

CONCLUSIONS

Food insecurity contributes to children's psychological distress. Given the known effects of chronic stress in childhood, the psychological distress of food insecurity may represent an important mechanism by which food insecurity adversely influences children's growth and development and deserves investigation in future studies.

A Systematic Review and Meta-analysis of Depression, Anxiety, and Sleep Disorders in US Adults with Food Insecurity

INTRODUCTION

A large number of peer-reviewed studies, with various methodologies and populations, have addressed the effects of food insecurity (FIS) on mental health conditions such as depression, anxiety, and sleep disorders. There are currently, however, no published systematic assessments or meta-analyses of this literature.

METHODS

A systematic search of the literature was conducted in PubMed, PsycInfo, Embase, Scopus, and Web of Science. Cross-sectional studies assessing the association between food insecurity and depression, anxiety, or sleep disorders were identified. For each of the three health outcomes, we extracted (or calculated when possible) the following effect sizes: odds ratio (OR), Hedges' g, Pearson correlation coefficients r, or bivariate coefficients. Then, for each mental health-outcome/effect-size pair, the available studies were combined using the random effect model. Heterogeneity, publication bias, and subgroup dependence, for each meta-analysis, were also assessed.

RESULTS

Fifty-seven studies provided cross-sectional data on the relationship between FIS and depression (n = 169,433), 13 on anxiety and psychological distress (n = 91,957), and 8 studies provided data on sleep disorders (n = 85,788). Meta-analysis showed that FIS is associated with an increased risk of testing positive for depression OR = 2.74 [95% CI 2.52-2.97, n = 135,500, Q(df = 41) = 69, I² = 40%], anxiety OR = 2.41 [95% CI 1.81-3.22, n = 51,541, Q(df = 3) = 8, I² = 63%], and sleep disorders OR = 1.80 [95% CI 1.51-2.15, n = 84,800, Q(df = 5) = 13, I² = 62%]. The highest risks were found for depression and anxiety which had statistically similar values. The results were robust to covariates and population groups.

DISCUSSION

This systematic review and meta-analysis demonstrates a strong association between FIS and depression, anxiety, and sleep disorders, for which more longitudinal studies addressing effect sizes are warranted to further study causation.

Prevalence and experiences of food insecurity among immigrant women connected to perinatal programs at a community-based organization in Edmonton, Canada

Purpose

The purpose of this paper is to investigate the prevalence of household food insecurity among immigrant women connected to perinatal programs offered through a community-based organization in Edmonton, and to explore their experiences in coping with food insecurity.

Design/methodology/approach

This study utilized a mixed methods research design. A community-based participatory research approach was used to engage health workers who were connected to immigrant women and families through the Multicultural Health Brokers Cooperative in Edmonton. Through the health workers a sample of 213 immigrant women connected to their perinatal programs completed the Household Food Security Survey. Following the survey, 17 women completed semi-structured interviews which were analyzed using content analysis.

Findings

The vast majority of women (94 percent (n=199)) lived in food insecure households, and 53 percent (n=112) in severely food insecure. In semi-structured interviews, women specifically described not having enough money to buy vegetables, fruit and meat, and perceiving a lack of control over foods they ate and offered to their families.

Practical implications

This study highlights the need for support to be provided to immigrant families for acquiring healthy food in Canada.

Originality/value

The mixed methods design with a decent sample of often underrepresented research participants highlights an area in need of further research and greater support.

Associação entre risco de transtornos mentais comuns e insegurança alimentar entre mães com filhos menores de um ano de idade

Resumo Insegurança alimentar e nutricional está relacionada a problemas nutricionais e de saúde, entretanto poucos estudos a relacionam com saúde mental. O objetivo deste artigo é Investigar associação da insegurança alimentar familiar e risco de transtornos mentais comuns (TMC) em mães com filhos de um ano de idade. Estudo de coorte prospectivo com 194 mães e seus filhos desde o nascimento. Insegurança alimentar foi medida aos quatro meses pós-parto, com a Escala Brasileira de Insegurança Alimentar e risco de diagnóstico positivo de TMC nas mães ao final do primeiro ano da criança, com o Self Response Questionnaire (SRQ-20). Medidas socioeconômicas e de saúde foram utilizadas como controle. Das famílias, 59,3% apresentavam insegurança alimentar, tendo razão de risco para diagnóstico de TMC de 1,59 (IC 95%: 1,10 – 2,31), comparado com famílias em segurança alimentar. Após ajuste, modelo logístico múltiplo estimou OR = 2,20 (IC 95%: 1,16 – 4,20) para esta relação. Observou-se associação da insegurança alimentar familiar aos quatro meses pós-parto e risco de diagnóstico de TMC entre mães ao final do primeiro ano dos filhos. O enfrentamento da insegurança alimentar deve fazer parte das estratégias promotoras da saúde materna e da qualidade de vida materno-infantil.

Canadian Children from Food Insecure Households Experience Low Self-Esteem and Self-Efficacy for Healthy Lifestyle Choices

The objectives of this cross-sectional study were to: (i) determine whether there are differences in self-esteem and self-efficacy for healthy lifestyle choices between children living in food secure and food insecure households; and (ii) determine whether the association between household food insecurity (HFI), self-esteem and self-efficacy differs by gender. Survey responses of 5281 fifth-grade students (10 and 11 years of age) participating in the Canadian Children’s Lifestyle and School Performance Study II were analyzed using logistic and linear regression. HFI status was determined by the six-item short-form Household Food Security Survey Module (HFSSM). Students from food insecure households had significantly higher odds of low self-esteem, and significantly lower scores for global self-efficacy to make healthy choices, compared to students from food secure households. These associations were stronger for girls than for boys and appeared independent of parental educational attainment. Household income appeared to be the essential underlying determinant of the associations of food insecurity with self-esteem and self-efficacy. Upstream social policies such as improving the household income of low-income residents will reduce food insecurity and potentially improve self-esteem and self-efficacy for healthy choices among children. This may improve health and learning, and in the long term, job opportunities and household earnings.

Suitability of the eight-item version of the Brazilian Household Food Insecurity Measurement Scale to identify risk groups: evidence from a nationwide representative sample

Objective

The Brazilian Household Food Insecurity Measurement Scale (EBIA) has eight general/adult items applied in all households and six additional items exclusively asked in households with children and/or adolescents (HHCA). Continuing an investigation programme on the adequacy of model-based cut-off points for EBIA, the present study aims to: (i) explore the capacity of properly stratifying HHCA according to food insecurity (FI) severity level by applying only the eight ‘generic’ items; and (ii) compare it against the fourteen-item scale.

Design

Latent class factor analysis (LCFA) models were applied to the answers to the eight general/adult items to identify latent groups corresponding to FI levels and optimal group-separating cut-off points. Analyses involved a thorough classification agreement evaluation and were performed at the national level and by macro-regions.

Setting

Data derived from the cross-sectional Brazilian National Household Sample Survey of 2013.

Participants

A nationally representative sample of 116 543 households.

Results

In all households and investigated domains, LCFA detected four distinct household food (in)security groups (food security and three levels of severity of FI) and the same set of cut-off points (1/2, 4/5 and 6/7). Misclassification in the aggregate data was 0·66 % in adult-only households and 1·06 % in HHCA. Comparison of the scale reduced to eight items with the ‘original’ fourteen-item scale demonstrated consistency in the classification. In HHCA, the agreement between both classifications was 96·2 %.

Conclusions

Results indicate the eight ‘generic’ items in HHCA can be reliably used when it is not possible to apply the fourteen-item scale.

The relationship between food security and quality of life among pregnant women

Background

Household food insecurity through influencing the quality and sufficiency of nutrition can have considerable effects on individuals’ health. Previous studies have shown the relationship between household food insecurity and quality of life among adults, infants, and people of minority ethnicity. However, no studies have been conducted on household food insecurity and quality of life among pregnant women. This study aimed to investigate the effect of food insecurity on quality of life among pregnant women in Qazvin city, Iran.

Methods

This cross-sectional study was conducted between May 2017 and November 2017 on 394 pregnant women. A random cluster sampling method was used to select eight urban health and medical centers from four geographical regions of Qazvin city, Iran. In the selected centers, pregnant women were recruited using eligibility inclusion criteria. Data was collected using the SF-36 Health-related Quality of Life, Household Food Insecurity Access Scale and a demographic questionnaire for recording the women’s gestational and demographic information through interviews. Descriptive and inferential statistics including Chi-square test, one-way analysis of variance with Bonferroni post-hoc test and multiple linear regression were used for data analysis. P < 0.05 was considered statistically significant.

Results

Food insecurity was reported in 43.9% of the pregnant women. Overall pregnant women’s quality of life had the highest score (Mean ± SD) in the domain of ‘social performance’ (76.4 ± 21) and the lowest one in the domain of ‘role limitation due to physical reasons’ (60.5 ± 43). Pregnant women with food insecurity had the lowest score in role limitation due to physical reasons domain of quality of life (68.6 ± 40.4, 61.3 ± 45.5 & 51.3 ± 47.7 respectively for mild, moderate and sever food insecurity). The results of multiple linear regression showed that one unit reduction of household food security significantly decreased the total quality of life score by 5.2 score (95% CI: -9.7, − 0.7) among the mild food insecure group, 10.8 score (95% CI: -17.1, − 4.6) among the moderate food insecure group and 14.1 score (95% CI: -19.7, − 8.5) among the sever food insecure group.

Conclusions

Screening of the household food security status during the primary prenatal care can identify high-risk pregnant women to improve the quantity and quality of their diet. Moreover multi-level actions including policy-making, supplying resources, and providing appropriate services are needed to ensure that pregnant women have access to high-quality foods.
