Nutritional health is essential for children’s growth and development. Many Mexican-origin children who reside in limited-resource colonias along the Texas-Mexico border are at increased risk for poor nutrition as a result of household food insecurity. However, little is known about the prevalence of child hunger or its associated factors among children of Mexican immigrants. This study determines the prevalence of child hunger and identifies protective and risk factors associated with it in two Texas border areas.
This study uses 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA) data from 470 mothers who were randomly recruited by promotora-researchers. Participants from colonias near two small towns in two South Texas counties participated in an in-home community and household assessment. Interviewer-administered surveys collected data in Spanish on sociodemographics, federal food assistance program participation, and food security status. Frequencies and bivariate correlations were examined while a random-effects logistic regression model with backward elimination was used to determine correlates of childhood hunger.
Hunger among children was reported in 51% (n = 239) of households in this C-HCFRA sample. Bivariate analyses revealed that hunger status was associated with select maternal characteristics, such as lower educational attainment and Mexican nativity, and household characteristics, including household composition, reliance on friend or neighbor for transportation, food purchase at dollar stores and from neighbors, and participation in school-based nutrition programs. A smaller percentage of households with child hunger participated in school-based nutrition programs (51%) or used alternative food sources, while 131 households were unable to give their child or children a balanced meal during the school year and 145 households during summer months. In the random effects model (RE = small town), increased household composition, full-time unemployment, and participation in the National School Lunch Program were significantly associated with increased odds for child hunger, while participation in Supplemental Nutrition Assistance Program (SNAP) and purchasing food from a neighbor were significantly associated with decreased odds for child hunger.
This study not only emphasizes the alarming rates of child hunger among this sample of Mexican-origin families, but also identifies economic and family factors that increased the odds for child hunger as well as community strategies that reduced the odds. It is unsettling that so many children did not participate in school-based nutrition programs, and that many who participated in federal nutrition assistance programs remained hungry. This study underscores the importance of identifying the presence of child hunger among low-income Mexican-origin children in Texas border colonias and increasing access to nutrition-related resources. Hunger-associated health inequities at younger ages among colonia residents are likely to persist across the life span and into old age.

Hunger among children is a serious public health problem in the U.S. and reflects an insufficient quantity and quality of food consumed [1, 2]. The Community Childhood Hunger Identification Project (CCHIP) defined hunger “as the mental and physical condition that comes from not eating enough food, due to insufficient economic, family or community resources” . Others have referred to hunger that is due to limited assets as resource-constrained hunger . The uncertainty of adequate food supplies among Hispanics and Mexican-origin U.S. households exceeds national estimates and is more common in households with children than in those that are childless [5, 6]. At the same time, nutrition-related health conditions, such as obesity and type 2 diabetes, are more prevalent and dramatically increasing in Mexican-origin children than other racial/ethnic groups [7–9]. Very low food security (formerly labeled food insecurity with hunger) describes disrupted eating patterns and reduced intake because of insufficient resources . Prior reports have classified food insecurity with hunger as present when one or more household members were hungry at least some time during the described time period because they could not afford enough food . Among children of Mexican immigrant parents, very low food security is associated with greater dietary intakes of total calories and percentage of calories from fat and added sugar .
Child hunger, as both a poor outcome and risk factor for adverse health and development , is a serious challenge facing children [13, 14]. A direct link has been established between inadequate food quality and quantity and poor mental and physical health, psychosocial, behavioral, learning, family stress, and academic outcomes [3, 15–24]. Mexican American children and children living in immigrant households are at the greatest risk for hunger [6, 14, 25–27]. Texas is home to the second largest number of foreign-born residents from Mexico and more than 1.8 million children living in food insecure homes (the second largest absolute number of children living in food insecure households in the U.S.), with the greatest density in Texas near the border with Mexico [28, 29].
The 2009 C-HCFRA was conducted in 44 colonias in two geographic areas in the Texas border region between September 10, 2009 and September 28, 2009: 19 colonias in or near the small town of Progreso in Hidalgo County and 25 colonias in or near La Feria in Cameron County. The point prevalence survey was conducted to document food insecurity, food access, and retail food store utilization among 610 Mexican-origin families along the Texas-Mexico border. Details of training, participant eligibility and recruitment, and administration of the Spanish-language in-person survey by highly trained promotora-researchers have been previously described in detail . Promotora-researchers are community-based health workers, certified as Community Health Workers (C.H.W.) by the State of Texas, Human Subjects certified, and are able to establish trust with respondents . There were two teams of two promotora-researchers who conducted the surveys in the same areas; one team of two worked in the Progreso area and the other team of two worked in the La Feria area. All four promotora-researchers resided in Hidalgo County, but had outreach experience in multiple Lower Rio Grande Valley counties. The survey instrument was specifically developed for this project and all protocols were approved by the Texas A&M Institutional Review Board, and each parent/caregiver provided informed consent. Since the focus of this analysis was child hunger, data were restricted to 470 (77.0%) households with at least one child under the age of 18 years in residence. All surveys were conducted in Spanish.
C-HCFRA survey data included individual resources (age, education, and country of birth of parent/caregiver), economic resources (household income and employment status for all adults), family resources (household composition and transportation), and community resources (retail food stores used, participation in nutrition assistance programs, perception of the food environment, and alternative food sources). Nutrition assistance programs included Supplemental Nutrition Assistance Program (SNAP), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), School Breakfast Program (SBP), and National School Lunch Program (NSLP). Perception of the community (local) food environment was assessed by three items on a four-point Likert scale (strongly agree, agree, disagree, or strongly disagree): 1) little variety in the types of foods that can be purchased; 2) few grocery stores or supermarkets; and 3) high food prices . Binary variables were constructed as strongly agree/agree vs. all others. The utilization of alternative retail food sources included the purchase of food from mobile food vendors, pulgas (flea markets), and neighbors or friends [34, 35]. Respondents were not asked about their immigration status.
Hunger was measured using two items from the 12-item Radimer/Cornell measure of hunger and food insecurity [36, 37]. Adult hunger was defined by responding that the following statement was ‘sometimes true’ or ‘often true’: “I am hungry but don’t eat because I can’t afford enough food.” Child hunger was defined by responding that the following statement was ‘sometimes true’ or ‘often true’: “I know my child(ren) is (are) hungry sometimes, but I just can’t afford more food.” Adult hunger and child hunger were each constructed as binary variables: present (sometimes/often true) vs. absent (not true).
All Spanish-language survey data were recorded in a relational database using double-key entry to minimize data entry error. All statistical analyses were conducted using Stata Statistical Software (Release 12.1, 2011, Stata Corporation, College Station, TX); p <0.05 was considered statistically significant. Descriptive statistics were estimated for the total sample and by child hunger status. Bivariate associations between all measures and child hunger (child hunger vs. no child hunger) were calculated using chi square analyses for categorical variables and Student’s t-tests for continuous variables. To account for correlation of child hunger by geographical location, a random effects (RE) logistic regression model was used with households nested within small town of residence (Progreso vs. La Feria) . All statistically significant (p ≤ 0.10) predictor variables from bivariate analyses were simultaneously entered into the model. Backward elimination sequentially removed non-significant variables in order to obtain the “best” set of independent variables . Model goodness of fit was assessed using Akaike Information Criterion (AIC), which is a measure of fit and complexity [40, 41].

Table 2 describes community resources such as grocery purchase, nutrition assistance program participation, and the local food environment. A greater percentage of households with child hunger shopped for groceries at a supercenter or dollar store compared to households without child hunger. La Feria area residents were more likely to shop at a supermarket for groceries (78% vs. 45.7% for Progreso, p <0.001); Progreso residents were more likely to shop at a supercenter (76.2% vs. 39.7%, p <0.001) or dollar store (43.4% vs. 1.4%, p <0.001). More than 63% of households received SNAP benefits. For households with child hunger, SNAP benefits did not last as long as in households without hungry children. The length of time SNAP benefits lasted was not associated with household composition (results not shown). Although SNAP participation rates were similar between the two geographic areas (65.4% for La Feria and 61.7% for Progreso), Progreso SNAP participants, compared with La Feria SNAP participants, received lower benefits each month ($334.38 vs. $382.96, p = 0.035), and their benefits lasted fewer days (19.7 days vs. 22.1 days, p = 0.008). Almost 15% of Progreso SNAP participants reported that their benefits did not last two weeks, compared with 5.1% of La Feria SNAP participants.
Almost 30% of households with children under the age of 5 years did not participate in WIC. A smaller percentage of households with child hunger reported participation in school-based nutrition programs (SBP or NSLP) or used alternative food sources (neighbor, MFV, or pulga), while a much larger percentage were unable to give their child or children a balanced meal during the school year or summer months. Progreso residents with school-age children reported significantly lower participation rates for both SBP and NSLP than did La Feria residents with school-age children.

Hunger among children is a serious challenge to children’s optimal development, health, behavior, and academic performance [1, 16, 19, 43, 44]. Although child hunger is a problem faced by all children in the United States today , it is of increasing concern among the growing population of Mexican-origin children. This is apparently the first study to document the high prevalence of child hunger among a large sample of low-income Mexican-origin and Mexican immigrant families in Texas border colonias. Findings from this study focus our attention on child hunger, the most severe subcategory of food insecurity [46, 47], and the presence or absence of individual, economic, family, and community resources that are associated with childhood hunger. This study relies on a comprehensive home- and community-based nutrition assessment of 470 low-income Mexican-origin families in colonias situated in two small towns along the Texas-Mexico border and helps answer the question: why do some very low-income families experience child hunger while others do not?
Results document the unacceptably high prevalence of child hunger and the large number of children potentially affected. Fifty-one percent of households reported child hunger, which accounted for 53% (n = 598) of all children. This far exceeds 2011 national estimates that 17.4% of Hispanic households had food-insecure children and 1.9% with very low food security among children . It also exceeds other prior reports of Latino children of immigrant parents , and challenges the belief that hunger is relatively uncommon in this population , suggesting to us not only that child hunger should be assessed in a broader array of Latino communities rather than relying on nationwide estimates to assess its prevalence, but that national estimates do not capture the prevalence of hunger among concealed or hard-to-reach communities suffering from great poverty. Child hunger can be thought of as a serious outcome of food insecurity, constrained dietary options, and compensatory strategies . Among children, hunger is a serious risk factor for long-term poor health, higher rates of chronic illness, stressful life events, poor educational achievement, and poor financial attainment in adulthood [14, 19, 21]. A child’s repeated exposure to hunger can be considered toxic .
This study not only emphasizes the alarming rates of child hunger for this sample of Mexican-origin families, but describes associations between population characteristics and the presence of child hunger. Coleman-Jensen reported that risk factors for higher rates of very low food security among children include households with children headed by a single woman, Hispanic households, and low-income households . In this study of Mexican-origin households, unadjusted analyses revealed that mother’s age, education, country of birth (Mexican immigrant), household size, and household income were associated with child hunger. A greater proportion of households with child hunger relied on a friend or neighbor for transportation in order to purchase groceries, did not participate in school-based nutrition programs, or did not purchase food from a neighbor or at a pulga.
It is well recognized that consuming a breakfast meal is important to the nutritional health of all children and adolescents [49–51]. For low-income families, the School Breakfast Program (SBP) is an important component of the safety net for children and has been linked to improved nutrient intake [52, 53]. In this sample, 38.2% of all households and 49.2% of child hunger households did not participate in SBP. In this sample, participation may be equivalent to utilization. Poor participation or utilization of SBP could result from types of foods offered or student arrival times. In areas where most children take the school bus, bus arrival may not coincide with SBP times. Underutilization of SBP could result in reduced nutrient intakes , and lower quality diets. Interestingly, a national study found that SBP appeared to offset food-related concerns among at-risk families, but not necessarily alleviate food insecurity once the threshold had been crossed . This may help explain why 50.8% of child hunger households were SBP participants. Although the National School Lunch Program (NSLP) is the largest child nutrition assistance program , 37.9% of households did not participate in NSLP. Lower participation or utilization could result from available food choices or limited amount of time for lunch. Similar to SBP, 51.3% of child hunger households participated in NSLP. In the present study, a greater percentage of households that reported no adult or child hunger participated in the SBP or NSLP compared to those households with adult or child hunger. There are unknown aspects of SBP and NSLP which may contribute to the differential participation rates seen in this analysis.
Key findings from our adjusted random effects regression model document that no one in the household employed full time, household composition, and participation in the NSLP were associated with increased odds for the presence of child hunger. Lack of full-time employment may entail a limited capacity to acquire economic resources. Household composition indicates a greater demand on household food supplies operationalized through increased size of household and greater food requirements . It was apparent that while participation in NSLP served to buffer some households from hunger among children, it did not do the same for all households. Although there can still be benefits from NSLP , for many households it may not be enough to prevent hunger among children. To address hunger among children, there are three issues that will need to be addressed: 1) difference between participation and utilization of NSLP and SBP; 2) potential need for supplemental nutrition programs for school-age children for evening meals and meals on weekends; and 3) further consideration of the adequacy of the Summer Food Service Program which is intended to substitute for the summertime absence of NSLP and SBP. Interestingly, households with a child 5 years, which suggests ineligibility for WIC or SBP/NSLP for that child, were 56% less likely report hunger among children. This may be explained by higher participation rates of these households in SNAP.
There were two types of community resources that were protective: participation in SNAP and purchasing food from a neighbor or friend were associated with reduced odds for child hunger. Contrary to prior work with Latino immigrant children that found no association between food stamps (SNAP) and child hunger , this study found, independent of economic and family resources that SNAP-participating households were more than two times less likely to report child hunger than households that did not participate in SNAP. SNAP, which is the largest food assistance program in the U.S. , is known to free up household resources , reduce very low food security over time , and minimize the positive associations of household and child food insecurity with children’s poor health . Still, SNAP participation does not prevent hunger or food insecurity [4, 58]. In this sample, 59% of households with child hunger were SNAP recipients. This calls into question the adequacy of SNAP benefits, which is influenced by financial and time resources and individual, household, and community factors that impact the purchasing power of benefits . Although this is a common finding among cross sectional analyses of SNAP and food insecurity, Nord and colleagues discovered in a longitudinal analysis that positive associations are the result of self-selection into SNAP by families as they first go without food, and that SNAP eventually plays a palliative role for household hunger . The negative association between SNAP and child hunger in this study is, we believe, indicative of households in receipt of SNAP benefits that commonly experience food insecurity and have thus largely moved beyond a tipping point for self-selection into SNAP participation. Although participation in SNAP was protective from child hunger in this sample, child hunger was present in 59% of households utilizing SNAP, and SNAP was not enough to prevent child hunger. This is more than twice the prevalence rate (23%) among low-income families previously reported in CCHIP . In part, this child hunger may result from the level of support, household size, length of time that benefits last, budget management skills, or amount of competing demands for limited resources. In our subgroup analysis of SNAP participants, the odds for childhood hunger were greater for households in which SNAP benefits lasted less than all month. In addition, a large percentage of participants were not utilizing SNAP, perhaps the result of perceived or actual eligibility for individual household members (e.g., mixed-status families with an undocumented parent and U.S.-born child),  language or educational barriers, immigration status and fear of deportation, or fear of stigmatization [47, 61, 62]. A recent report from the Institute of Medicine made several recommendations to increase the adequacy of SNAP benefits . These include consideration of specific individual, household, and environmental factors on determining the adequacy of SNAP allotment, which recognizes cost–time trade-offs, geographic variation in food prices, and spatial access to retail food sources.
There has been little consideration given to alternative food sources, which represent a unique and previously unmeasured compensatory strategy to improve food security . In this study, the odds of child hunger in households whose inhabitants purchased food from a neighbor or friend were 49% less likely than households that did not rely on this compensatory practice. This strategy illustrates resiliency and community connectedness and may provide colonia residents with the opportunity to preserve limited economic and family resources by reducing travel cost and increasing the frequency at which food may be purchased as needed and in smaller quantities.
There are several limitations to this cross-sectional study. First, immigration status (e.g., naturalized citizen of the U.S. or legal resident) was not assessed . Thus, we do not know what percentage of the 322 Mexican immigrants in this study were undocumented or were in mixed-status households. This may explain why a significantly larger percentage of Mexican immigrant households reported hungry children. Prior studies reported that limited access to safety net public assistance may contribute to high levels of hunger, especially for the undocumented, but could also affect legal immigrants . In other studies of Latino immigrants, immigration status was not assessed [14, 46, 63]. Second, adult and child experiences of hunger were based only on mothers’ report. Prior work demonstrated that children are able to report their own food insecurity experiences, which may differ from proxy reports by the mother [12, 64]. Third, data were not available regarding forms of material hardship unrelated to food insecurity that result in competing demands for strained household economic resources. Fourth, the data did not attribute child hunger to specific children, or how the availability of food varied among household members. Fifth, data were not available on the frequency or duration of adult or child hunger. Was this persistent or new? In a recent government report, of households that reported child(ren) were hungry, 23% experienced the condition almost every month and 51% endured it for a period of several months . Finally, there is some concern on the low reporting of participation in SBP and NSLP, which may be indicative of lack of utilization of the programs or not knowing the names of the programs within the schools.
Notwithstanding these limitations, there are a number of strengths to this study, including a large sample of immigrant and hard-to-reach Mexican-origin households and comprehensive data collected in Spanish during in-person interviews conducted by trained promotora-researchers. The results of this study further our understanding of child hunger among Mexican-origin households in Texas border colonias. In documenting an unacceptably high exposure of children to hunger, which may influence dietary intake and health outcomes, the results confirm the important role of safety net programs, such as SNAP. However, the results may understate the degree of child hunger during the summer months when children are not in school and away from SBP and NSLP . A large percentage of potentially eligible households did not participate in these nutrition assistance programs. There may be restrictions on immigrants which may ultimately affect the health of children. Efforts must be made to increase access to food-related resources, expand the availability of meals for low-income children, and ensure that all eligible families, especially mixed-status families receive nutrition assistance. In the end, child hunger raises serious concerns for communities. Considering the important relationship between child hunger and adverse mental and physical health outcomes among low-income children , this study underscores the importance of identifying the presence of child hunger among low-income Mexican-origin children and increasing access to nutrition-related resources. Health inequities at younger ages among the Mexican-origin population are likely to persist across the lifespan and into old age, with an accumulation of risk . Our findings support the identification of child hunger as a possible target for screening and interventions to prevent poor developmental and health outcomes, and the importance of improved culturally-specific communication with Mexican-origin residents about availability of community and federal nutrition resources . SNAP and school-based nutrition assistance programs are critical to millions of people, especially children. However, in the case of SNAP, efforts should be undertaken as suggested by the recent IOM report to define the adequacy of the SNAP allotment and make adjustments accordingly . In the case of school-based nutrition programs, acceptable meals and sufficient time for consuming SBP and NSLP meals should be made available to all children at risk of or experiencing hunger. Creative approaches, such as provision of a third meal and meals on weekends, should be explored. Our greatest return on the investment in these feeding programs is in ensuring that all children and families have access to affordable and healthy food supplies. Further explorations on strategies to address child hunger with young mothers are needed that incorporate both knowledge and skill-building. Ideally, this would include the empowerment of promotoras to deliver culturally- and linguistically-appropriate interventions and strategies.
