RESUMEN

BACKGROUND: The risk of spinal cord ischemia (SCI) with aortic aneurysm repair can cause significant neurological morbidity. Prevention of SCI is critical. We sought to identify risk factors that predispose to SCI that may guide strategies to mitigate the occurrence of SCI during and following these procedures. METHODS: This study includes all adults who underwent atraumatic, unruptured, thoracic, and suprarenal aortic aneurysm repairs (endovascular or open) at our institution over 11 years (2010-2020). Our database included patient demographics, aneurysm anatomic features, and operative characteristics and an extreme gradient boost (XGB) machine method was used to develop a predictive model for SCI. The model was trained on an 80% randomly stratified cohort of the data and tested on the remaining 20% testing cohort. Shapley values were used to determine the most important predictive factors of SCI and decision trees were used to identify risk factor threshold values and highest risk factor combinations. RESULTS: Information was collected for 174 adult patients undergoing thoracic and suprarenal aortic repair from 2010 to 2020. Fifty eight percent of the patients were male. Ninety seven (55.7%) patients had open aortic repair and 87 (44.3%) had endovascular repair. Twenty seven (15%) of all patients had major complications and were considered to have SCI. The XGB model converged over the training cohort with a testing cohort accuracy of 0.841 [Sensitivity = 75%, Specificity = 68%] and area under the curve of receiver operating characteristic of 0.774. The XGB model identified older age (> 65 years), history of neurologic disease, hyperlipidemia, diabetes, coronary artery disease, heart failure, poor renal function, < 6 months since last aortic repair, chronic anticoagulant use, preoperational anemia (Hemoglobin < 9), thrombocytopenia (platelet < 90,000), coagulopathy (prothrombin time > 15s and activated partial thromboplastin time > 40s), hypotension (mean arterial pressure < 70 mm Hg), longer operations (> 100 min), aneurysms longer than 5 cm, and anatomic location of aneurysm caudal to T-11 as risk factors for SCI in all types of aortic repair. Diabetic and heart failure patients undergoing longer operations (> 100 min) with thrombocytopenia or aneurysms longer than 5 cm were at the highest risk. CONCLUSIONS: The XGB model accurately identified risk factors of SCI with aortic aneurysm repair that may guide patient selection, timing of surgery, and strategies to minimize the risk of SCI.

RESUMEN

Evaluate homelessness during pregnancy as a unique, time-dependent risk factor for adverse birth outcomes. 9,995 mothers of children <48 months old surveyed at emergency departments and primary care clinics in five US cities. Mothers were classified as either homeless during pregnancy with the index child, homeless only after the index child's birth, or consistently housed. Outcomes included birth weight as a continuous variable, as well as categorical outcomes of low birth weight (LBW; <2,500 g) and preterm delivery (<37 weeks). Multiple logistic regression and adjusted linear regression analyses were performed, comparing prenatal and postnatal homelessness with the referent group of consistently housed mothers, controlling for maternal demographic characteristics, smoking, and child age at interview. Prenatal homelessness was associated with higher adjusted odds of LBW (AOR 1.43, 95 % CI 1.14, 1.80, p < 0.01) and preterm delivery (AOR 1.24, 95 % CI 0.98, 1.56, p = 0.08), and a 53 g lower adjusted mean birth weight (p = 0.08). Postnatal homelessness was not associated with these outcomes. Prenatal homelessness is an independent risk factor for LBW, rather than merely a marker of adverse maternal and social characteristics associated with homelessness. Targeted interventions to provide housing and health care to homeless women during pregnancy may result in improved birth outcomes.

RESUMEN

OBJECTIVES: We investigated the association between housing insecurity and the health of very young children. METHODS: Between 1998 and 2007, we interviewed 22,069 low-income caregivers with children younger than 3 years who were seen in 7 US urban medical centers. We assessed food insecurity, child health status, developmental risk, weight, and housing insecurity for each child's household. Our indicators for housing insecurity were crowding (> 2 people/bedroom or>1 family/residence) and multiple moves (≥ 2 moves within the previous year). RESULTS: After adjusting for covariates, crowding was associated with household food insecurity compared with the securely housed (adjusted odds ratio [AOR] = 1.30; 95% confidence interval [CI] = 1.18, 1.43), as were multiple moves (AOR = 1.91; 95% CI = 1.59, 2.28). Crowding was also associated with child food insecurity (AOR = 1.47; 95% CI = 1.34, 1.63), and so were multiple moves (AOR = 2.56; 95% CI = 2.13, 3.08). Multiple moves were associated with fair or poor child health (AOR = 1.48; 95% CI =1.25, 1.76), developmental risk (AOR 1.71; 95% CI = 1.33, 2.21), and lower weight-for-age z scores (-0.082 vs -0.013; P= .02). CONCLUSIONS: Housing insecurity is associated with poor health, lower weight, and developmental risk among young children. Policies that decrease housing insecurity can promote the health of young children and should be a priority.

RESUMEN

The effects of housing instability and homelessness on child and adult health are well documented. However, few studies have explored health and housing interventions for families with children with the objective of health improvement. Housing Prescriptions as Health Care is a randomized controlled trial that is investigating the impact on physical and mental health of integrating priority placement in affordable housing and the provision of services (case management, financial, and legal), compared to the standard of care (providing resource guides and hospital-based social work or care navigation services). In 2016-19 seventy-eight homeless or housing-unstable families defined as "medically complex"-with a child or adult member who used more health services than usual or had a chronic disease or disability-were enrolled in the trial, and sixty-seven completed a six-month follow-up. A difference-in-differences analysis at six months showed decreases in the share of children in fair or poor health and in average anxiety and depression scores among parents in the intervention group, relative to the control group. Findings suggest that a population-specific model that integrates health, housing, legal, and social services can improve health-related outcomes at the household level.

RESUMEN

BACKGROUND AND OBJECTIVES: Food insecurity and pediatric obesity affect young children. We examine how food insecurity relates to obesity, underweight, stunting, health, and development among children <4 years of age. METHODS: Caregivers of young children participated in a cross-sectional survey at medical centers in 5 US cities. Inclusion criteria were age of <48 months. Exclusion criteria were severely ill or injured and private health insurance. The Household Food Security Survey Module defined 3 exposure groups: food secure, household food insecure and child food secure, and household food insecure and child food insecure. Dependent measures were obesity (weight-age >90th percentile), underweight (weight-age <5th percentile), stunting (height/length-age <5th percentile), and caregiver-reported child health and developmental risk. Multivariable logistic regression analyses, adjusted for demographic confounders, maternal BMI, and food assistance program participation examined relations between exposure groups and dependent variables, with age-stratification: 0 to 12, 13 to 24, 25 to 36, and 37 to 48 months of age. RESULTS: Within this multiethnic sample (N = 28 184 children, 50% non-Hispanic African American, 34% Hispanic, 14% non-Hispanic white), 27% were household food insecure. With 1 exception at 25 to 36 months, neither household nor child food insecurity were associated with obesity, underweight, or stunting, but both were associated with increased odds of fair or poor health and developmental risk at multiple ages. CONCLUSIONS: Among children <4 years of age, food insecurity is associated with fair or poor health and developmental risk, not with anthropometry. Findings support American Academy of Pediatrics recommendations for food insecurity screening and referrals to help families cope with economic hardships and associated stressors.

RESUMEN

INTRODUCTION: The Supplemental Nutrition Assistance Program (SNAP) is the largest nutrition assistance program in the U.S. This study's objective was to examine the associations between SNAP participation and young children's health and development, caregiver health, and family economic hardships. METHODS: Cross-sectional data from 2006 to 2016 were analyzed in 2017 for families with children aged <3 years in 5 cities. Generalized estimating equations and logistic regression were used to evaluate the associations of SNAP participation with child and caregiver health outcomes and food insecurity, forgone health care, and health cost sacrifices. Nonparticipants that were likely to be eligible for SNAP were compared with SNAP participants and analyses adjusted for covariates including Consumer Price Index for food to control for site-specific food prices. RESULTS: The adjusted odds of fair or poor child health status (AOR=0.92, 95% CI=0.86, 0.98), developmental risk (AOR=0.82, 95% CI=0.69, 0.96), underweight, and obesity in children were lower among SNAP participants than among nonparticipants. In addition, food insecurity in households and among children, and health cost sacrifices were lower among SNAP participants than among nonparticipants. CONCLUSIONS: Participation in SNAP is associated with reduced household and child food insecurity, lower odds of poor health and growth and developmental risk among infants and toddlers, and reduced hardships because of healthcare costs for their families. Improved SNAP participation and increased SNAP benefits that match the regional cost of food may be effective preventive health strategies for promoting the well-being of families with young children.

RESUMEN

The Supplemental Nutrition Assistance Program (SNAP) helps working families meet their nutritional needs. Families whose earned income increases in a given month may have their SNAP benefits abruptly reduced or cut off in the following month. Using sentinel sample data from 2007-15 for families with children younger than age four, we investigated how SNAP benefit reductions or cutoffs resulting from increased income were related to economic hardships (food and energy insecurity, unstable housing, forgone health and/or dental care, and health cost sacrifices) and to caregiver and child health. After we controlled for covariates, we found that the groups whose SNAP benefits were reduced or cut off had significantly increased odds of household and child food insecurity, compared to a group with consistent participation in SNAP. Reduced benefits were associated with 1.43 and 1.22 times greater odds of fair or poor caregiver and child health, respectively. Policy modifications to smooth changes in benefit levels as work incomes improve may protect working families with young children from increased food insecurity, poor health, and forgone care.

RESUMEN

BACKGROUND: As part of the USDA-Department of Health and Human Services Pregnancy and Birth to 24 Months Project, we conducted systematic reviews (SRs) on topics important for health and nutrition of young children. OBJECTIVES: The purpose of the present SR was to examine the relation between caregiver feeding practices in children from birth to 24 mo and child weight gain, size, and body composition. METHODS: A search of articles published from January 1980 to January 2017 in 4 databases identified 8739 references. Nutrition Evidence Systematic Review (NESR) analysts used the Nutrition Evidence Library Risk of Bias Assessment Tool to assess potential bias in the studies, and a Technical Expert Collaborative graded the body of evidence using the NESR grading rubric. RESULTS: Twenty-seven articles were included in this review (8 controlled trials, 19 longitudinal cohort studies). Moderate evidence from randomized controlled trials suggests that providing responsive feeding guidance to teach mothers to recognize and respond appropriately to children's hunger and satiety cues can lead to "normal" weight gain and/or "normal" weight status in children aged ≤2 y compared with children whose mothers did not receive responsive feeding guidance. Moderate evidence from longitudinal cohort studies indicates an association between maternal feeding practices and the child's weight status and/or weight gain, but the direction of effect has not been adequately studied. Restrictive feeding practices are associated with increased weight gain and higher weight status, and pressuring feeding practices are associated with decreased weight gain and lower weight status. Evidence suggests that a mother's feeding practices are related to concerns about her child's body weight. CONCLUSIONS: This review highlights the importance of the interaction between caregivers and infants and toddlers related to child feeding practices on children's weight outcomes. Research is needed on more diverse populations with consistent methodological app-roaches and objective measures.

RESUMEN

BACKGROUND: Maternal diet during pregnancy and lactation may provide the earliest opportunity to positively influence child food acceptance. OBJECTIVE: Systematic reviews were completed to examine the relation among maternal diet during pregnancy and lactation, amniotic fluid flavor, breast-milk flavor, and children's food acceptability and overall dietary intake. DESIGN: A literature search was conducted in 10 databases (e.g., PubMed, Embase, Cochrane, and CINAHL) to identify articles published from January 1980 to June 2017. Data from each included study were extracted, risk of bias assessed, evidence synthesized qualitatively, conclusion statements developed, and strength of the evidence graded. RESULTS: Eleven and 15 articles met a priori criteria for inclusion to answer questions related to maternal diet during pregnancy and lactation, respectively. CONCLUSIONS: Limited but consistent evidence indicates that flavors (alcohol, anise, carrot, garlic) originating from the maternal diet during pregnancy can transfer to and flavor amniotic fluid, and fetal flavor exposure increases acceptance of similarly flavored foods when re-exposed during infancy and potentially childhood. Moderate evidence indicates that flavors originating from the maternal diet during lactation (alcohol, anise/caraway, carrot, eucalyptus, garlic, mint) transmit to and flavor breast milk in a time-dependent manner. Moderate evidence indicates that infants can detect diet-transmitted flavors in breast milk within hours of a single maternal ingestion (alcohol, garlic, vanilla, carrot), within days after repeated maternal ingestion (garlic, carrot juice), and within 1-4 mo postpartum after repeated maternal ingestion (variety of vegetables including carrot) during lactation. Findings may not generalize to all foods and beverages. Conclusions cannot be drawn to describe the relationship between mothers' diet during either pregnancy or lactation and children's overall dietary intake.

RESUMEN

BACKGROUND: Repeated exposure has been found to be an effective strategy to increase acceptability of foods in older children and adults, but little is known about its effectiveness in the birth to 24-mo population. OBJECTIVES: This systematic review was conducted to examine the effects of repeated exposure to a single or multiple foods on acceptance of those or other foods among infants and toddlers. METHODS: A search was conducted for peer-reviewed articles related to food acceptability, flavor, taste, and infants and toddlers in 12 databases (e.g., PubMed, Embase, Cochrane, and CINAHL) with a date range of January 1980 to July 2017. The Nutrition Evidence Library (NEL) Bias Assessment Tool was used to assess potential bias in the included studies, and the NESR grading rubric was used to grade evidence supporting the conclusion statement. RESULTS: From the 10,844 references obtained, 21 studies (19 controlled trials and 2 longitudinal cohort studies) published from 1980 to 2015 were included in this review. Moderate evidence indicates that tasting a single vegetable or fruit or multiple vegetable(s) or fruit(s) 1 food per day for 8-10 or more days is likely to increase acceptability of an exposed food (indicated by an increase in intake or faster rate of feeding after comparison with before the exposure period) in infants and toddlers 4-24 mo old. The effect of repeated exposure on acceptability is likely to generalize to other foods within the same food category but not foods from a different food category. Findings are based on the effects of repeated exposure to mostly vegetables with some findings on repeated exposure to fruits. CONCLUSION: This review advances the understanding of early food experiences and the development of food acceptability. Additional research is needed using diverse foods and textures with a focus on the transition to table foods.

RESUMEN

Access to food is essential to optimal development and function in children and adults. Food security, food insecurity, and hunger have been defined and a U.S. Food Security Scale was developed and is administered annually by the Census Bureau in its Current Population Survey. The eight child-referenced items now make up a Children's Food Security Scale. This review summarizes the data on household and children's food insecurity and its relationship with children's health and development and with mothers' depressive symptoms. It is demonstrable that food insecurity is a prevalent risk to the growth, health, cognitive, and behavioral potential of America's poor and near-poor children. Infants and toddlers in particular are at risk from food insecurity even at the lowest levels of severity, and the data indicate an "invisible epidemic" of a serious condition. Food insecurity is readily measured and rapidly remediable through policy changes, which a country like the United States, unlike many others, is fully capable of implementing. The food and distribution resources exist; the only constraint is political will.

RESUMEN

OBJECTIVE: To examine the associations between breastfeeding and child health outcomes among citizen infants of mothers immigrant to the United States. DESIGN/METHODS: From September 1998 through June 2004, as part of the Children's Sentinel Nutrition Assessment Program, a sentinel sample of 3,592 immigrant mothers with infants aged 0 to 12 months were interviewed in emergency departments or pediatric clinics in six sites. Mothers reported breastfeeding history, child health history, household demographics, government assistance program participation, and household food security. Infants' weight and length were recorded at the time of visit. Bivariate analyses identified confounders associated with breastfeeding and outcomes, which were controlled in logistic regression. Additional logistic regressions examined whether food insecurity modified the relationship between breastfeeding and child outcomes. RESULTS: Eighty-three percent of infants of immigrants initiated breastfeeding. Thirty-six percent of immigrant households reported household food insecurity. After controlling for potential confounding variables, breastfed infants of immigrant mothers were less likely to be reported in fair/poor health (adjusted odds ratio [AOR] 0.65, 95% confidence interval [CI] 0.50 to 0.85; P=0.001) and less likely to have a history of hospitalizations (AOR 0.72, CI 0.56 to 0.93, P=0.01), compared to nonbreastfed infants of immigrant mothers. Compared to nonbreastfed infants, the breastfed infants had significantly greater weight-for-age z scores (0.185 vs 0.024; P=0.006) and length-for-age z scores (0.144 vs -0.164; P<0.0001), but there was no significant difference in risk of overweight (weight-for-age >95th percentile or weight-for-length >90th percentile) between the two groups (AOR 0.94, CI 0.73 to 1.21; P=0.63). Household food insecurity modified the association between breastfeeding and child health status, such that the associations between breastfeeding and child health were strongest among food-insecure households. CONCLUSIONS: Breastfeeding is associated with improved health outcomes for infants of immigrant mothers. Breastfeeding is an optimal strategy in the first year of life to improve all infants' health and growth, especially for children of immigrants who are at greater risk for experiencing food insecurity.

RESUMEN

OBJECTIVE: To determine whether peer counselors impacted breastfeeding duration among premature infants in an urban population. DESIGN: This was a randomized controlled clinical trial. SETTING: The trial was conducted in the Newborn Intensive Care Unit at Boston Medical Center, an inner-city teaching hospital with approximately 2000 births per year. PARTICIPANTS: One hundred eight mother-infant pairs were enrolled between 2001 and 2004. Pairs were eligible if the mother intended and was eligible to breastfeed per the 1997 guidelines from the American Academy of Pediatrics and if the infant was 26 to 37 weeks' gestational age and otherwise healthy. INTERVENTION: Subjects were randomized to either a peer counselor who saw the mother weekly for 6 weeks or to standard of care. MAIN OUTCOME MEASURE: The main outcome measure was any breast-milk feeding at 12 weeks postpartum. RESULTS: Intervention and control groups were similar on all measured sociodemographic factors. The average gestational age of infants was 32 weeks (range, 26.3-37 weeks) with a mean birth weight of 1875 g (range, 682-3005 g). At 12 weeks postpartum, women with a peer counselor had odds of providing any amount of breast milk 181% greater than women without a peer counselor (odds ratio, 2.81 [95% confidence interval, 1.11-7.14]; P = .01). CONCLUSIONS: Peer counselors increased breastfeeding duration among premature infants born in an inner-city hospital and admitted to the neonatal intensive care unit. Peer counseling programs can help to increase breastfeeding in this vulnerable population.

RESUMEN

BACKGROUND: Food insecurity (FI) refers to limited or uncertain access to food resulting from financial constraints. Numerous studies have shown association between FI and adverse health outcomes among adults and children around the world, but in Brazil, such information is scarce, especially if referring to nationally representative information. OBJECTIVE: To test for an independent association between FI and health outcomes. METHODS: Most recent Brazilian Demographic and Health Survey using nationally representative complex probability sampling. Participants were 3923 children <5 years of age, each representing a household. Data from the validated Brazilian Food Insecurity Scale were dichotomized as food secure (food security/mild FI) or food insecure (moderate FI/severe FI). Poisson regression was used to test for associations between FI and various health indicators. RESULTS: Models adjusted for socioeconomic and demographic variables showed that children hospitalized for pneumonia or diarrhea were 30% more prevalent in FI households (adjusted prevalence ratio [aPR]: 1.3; 1.1-1.6). Underweight children were 40% more prevalent in FI households (aPR: 1.4; 1.1-1.7). Children who didn't eat meat and fruits and vegetables every day were 20% and 70% more prevalent in FI households (aPR: 1.2; 1.1-1.4 and aPR: 1.7; 1.3-2.3), respectively. CONCLUSION: Children who grow up in food-insecure households have been shown to have worse health conditions than those in food-secure households. Consequently, their human capital accumulation and work-life productivity are likely to be reduced in the future, leading them into adulthood less capable of generating sufficient income, resulting in a cycle of intergenerational poverty and FI.

RESUMEN

CONTEXT: Welfare reform under the 1996 Personal Responsibility and Work Opportunity Reconciliation Act replaced entitlement to cash assistance for low-income families with Temporary Assistance to Needy Families, thereby terminating or decreasing cash support for many participants. Proponents anticipated that continued receipt of food stamps would offset the effects of cash benefit losses, although access to food stamps was also restricted. OBJECTIVE: To examine associations of loss or reduction of welfare with food security and health outcomes among children aged 36 months or younger at 6 urban hospitals and clinics. DESIGN AND SETTING: A multisite retrospective cohort study with cross-sectional surveys at urban medical centers in 5 states and Washington, DC, from August 1998 through December 2000. PARTICIPANTS: The caregivers of 2718 children aged 36 months or younger whose households received welfare or had lost welfare through sanctions were interviewed at hospital clinics and emergency departments. MAIN OUTCOME MEASURES: Household food security status, history of hospitalization, and, for a subsample interviewed in emergency departments, whether the child was admitted to the hospital the day of the visit. RESULTS: After controlling for potential confounding factors, children in families whose welfare was terminated or reduced by sanctions had greater odds of being food insecure (adjusted odds ratio [AOR], 1.5; 95% confidence interval [CI], 1.1-1.9), of having been hospitalized since birth (AOR, 1.3; 95% CI, 1.0-1.7) and, for the emergency department subsample, of being admitted the day of an emergency department visit (AOR, 1.9; 95% CI, 1.2-3.0) compared with those without decreased benefits. Children in families whose welfare benefits were decreased administratively because of changes in income or expenses had greater odds of being food insecure (AOR, 1.5; 95% CI, 1.1-2.2) and of being admitted the day of an emergency department visit (AOR, 2.8; 95% CI, 1.4-5.6). Receiving food stamps does not mitigate the effects of the loss or reduction of welfare benefits on food security or hospitalizations. CONCLUSION: Terminating or reducing welfare benefits by sanctions, or decreasing benefits because of changes in income or expenses, is associated with greater odds that young children will experience food insecurity and hospitalizations.

RESUMEN

This article explores whether social capital-a measure of trust, reciprocity and social networks-is positively associated with household food security, independent of household-level socioeconomic factors. Interviews were conducted in 330 low-income households from Hartford, Connecticut. Social capital was measured using a 7-item Likert scale and was analyzed using household- and community-level scores. Household food security and hunger were measured using the US Household Food Security Module. chi2 tests were used to examine associations between social capital, food security and household demographic characteristics. Logistic regression was used to examine whether household- and community-level social capital decreases the odds of household hunger, and to estimate which household characteristics increase the likelihood of having social capital. Consistent with our hypotheses, social capital, at both the household and community levels, is significantly associated with household food security in these data. Community-level social capital is significantly associated with decreased odds of experiencing hunger (adjusted odds ratio (AOR)=0.47 [95% CI 0.28, 0.81], P<0.01), while controlling for household socioeconomic status. Results show that households with an elderly member are over two and a half times as likely to have high social capital (AOR=2.68 [1.22, 5.87], P<0.01) than are non-elderly households, after controlling for socioeconomic status. Having a household member who participates in a social or civic organization is also significantly associated with having higher levels of social capital. Social capital, particularly in terms of reciprocity among neighbors, contributes to household food security. Households may have similarly limited financial or food resources, but households with higher levels of social capital are less likely to experience hunger.

RESUMEN

OBJECTIVE: To examine participation in the Food Stamp Program, food pantries, and soup kitchens and to identify reasons food-insecure households choose not to participate. DESIGN: Cross-sectional retrospective cohort study. SETTING: In respondents' homes. PARTICIPANTS: 330 randomly selected low-income households (below 185% of poverty). MAIN OUTCOME MEASURES: Participation in any of 3 public or private food assistance programs and barriers to participation in each program. ANALYSIS: Chi-square tests of association between program participation and sociodemographic characteristics. Logistic regression tested for associations between program participation and ethnicity and between food security status and household composition while controlling for potential confounding factors. RESULTS: Controlling for socioeconomic status, Black households are less than half as likely to receive food stamps (odds ratio [OR] = 0.49; P <.02) as Hispanic households. Hispanic households are more likely than non-Hispanic households to say that they feel uncomfortable using food pantries (P <.01). Elderly households are less than half as likely to receive food stamps (OR = 0.44; P =.04) as nonelderly households and are more likely to say that they feel uncomfortable receiving food stamps (P =.05). CONCLUSIONS AND IMPLICATIONS: Low-income households' perceptions of which programs are socially acceptable differ by race and age. Outreach for food stamps and private food assistance should accommodate these differences so that food-insecure households can benefit from all available food assistance.

RESUMEN

Poverty-related food insecurity is a reality that many clinicians in nutrition and health care encounter either directly or indirectly. It is associated with both overnutrition and undernutrition, but it is not congruent with malnutrition. Food insecurity affects human development and health throughout the lifecycle, but can be particularly harmful during critical or vulnerable stages early and late in life. Understanding the causes and consequences of food insecurity and knowing how to identify them can improve the quality and effectiveness of clinical care, and facilitate prevention and treatment of many kinds of health problems. Numerous public policies and programs exist to ameliorate and prevent poverty-related food insecurity. However, the resources to support them ebb and flow with the politics of annual state and federal budgetary cycles. Support and need for these social-safety-net programs also vary with business cycles. Unfortunately, need often expands as support shrinks along with employment and government revenues during recessions, and shrinks as support expands along with employment and government revenues during expansions.
