Summary and Implications


Introduction The phenomenon loosely labeled hunger in the 1980s is now being discussed as food security or insecurity. At a minimum it includes the following: The ready availability of nutritionally adequate and safe foods, and the assured ability to acquire personally acceptable foods in a socially acceptable way. The order of these qualifications reflects the current degree of consensus. The definition explicitly includes every person at all times; even though defining a situation that seems to be unattainable may seem counterproductive, a less inclusive definition cannot be justified on either ethical or nutritional bases. “Enough food for an active, healthy life” implies a diet with sufficient energy, nutritional quality and safety to prevent diet mediated malnutrition or limitations in activity levels. Food insecurity includes limited or uncertain access. “Socially acceptable ways” refer to conventional food sources such as grocery stores, restaurants and government food assistance programs “Personally acceptable” is included to reinforce the value our society places on freedom of choice; in practice, freedom of choice differentiates how cattle are fed from how humans acquire food.


Food insecurity is the inability to access enough food for a healthy and active lifestyle.

Low nutrient-dense diets may increase the risk for obesity or for micronutrient deficiencies, including iron deficiency. Dietary data have shown that

children from low-income food insecure households consume fewer calories, carbohydrates and fruits, and have higher cholesterol values than their food secure, higherincome peers. In addition food insecure-exposed children consume fewer fruits, dark green vegetables, grains, yogurt, nuts, seeds, and dried beans and peas, but more sugar and eggs than children from food-secure households, illustrating that the quality of children’s diets differ as a function of their food security status.

caregiver depression and anxiety pathway Most of the research on food insecurity has been crosssectional. However, several longitudinal investigations into the mechanisms linking household food insecurity with children’s health and development have used the Early Childhood Longitudinal Study, which includes the USDA Household Food Security Scale. Two studies found that food insecurity operates through maternal depression and parenting to negatively impact children’s mental development and attachment and to promote overweight by 24 months. Early in life, children and caregivers establish


Physical Effects Among women, food insecurity without hunger appears to be associated with obesity. Analyses of NHANES III data showed that women, but not men, in food-insufficient households were more likely to be overweight than were food-sufficient women (58% compared with 47%). In another study, food-insecure women were more than ten pounds heavier on average than was the comparison group. Whereas links between food insecurity and lower diet quality might be expected, the association between food insecurity and obesity was something of a paradox. Given that low-income families are the chief beneficiaries of food-assistance programs, exploration of the causal connections between food insecurity and obesity has major implications for food and nutrition policies in the United States.

The Role of Energy Density Costs


t he rol e of en ergy d en s it y c os t s

energy-density cost framework In 1992, Basiotis hypothesized and confirmed a behavioral model in which household members faced with diminishing incomes first consumed less expensive foods to maintain energy intakes at a lower cost. To multiple-choice questions about food sufficiency, these participants responded â&#x20AC;&#x153;enough but not the kinds of food we want to eat,â&#x20AC;? which implied adequate energy intakes but a limited range of food choices. Only when incomes diminished still further did households reduce dietary energy to intakes below daily requirements, which resulted in overt deprivation. Food restriction at home first occurs in adults because parents typically turn over their own food to children when resources are scarce. In the present framework, the association between poverty and obesity is mediated, at least in part, by the low cost of energy-dense foods, which may in turn promote overconsumption. The hypothesis is that energy density and energy costs are inversely linked, such that the selection of energy-dense foods by food-insecure or low-income consumers may represent a deliberate strategy to save money. Analogous to the findings of Basiotis, persons attempting to limit food costs will first select less expensive but more energy-dense foods to maintain dietary energy. The energy-cost curve linking food costs with dietary energy density and energy intakes is shown below. As food costs diminish further, dietary energy density rises, and total energy intakes may actually increase. Some of the evidence linking dietary energy density with higher energy intakes is outlined in the following pages.

The current US diet derives close to 50% of energy from added sugars and fat. Data from the Economic Research Service of the USDA show that the per capita availability of caloric sweeteners and fats and oils each increased by about 20% between 1977 and 1997. Retail price increases during that time were much lower for sweets and fats than for vegetables and fruit. Other studies have shown that foods identified as accounting for the greatest increase in energy intake by Americans during that time were salty snacks, desserts, soft drinks, fruit drinks, hamburgers and cheeseburgers, Mexican food, and pizza. In 1977–1978, these foods combined accounted for 18.1% of the dietary energy consumed by Americans and for 27.7% of energy in 1994–1996. For the most part, many such foods are composed of refined grains, added sugars, and fats. Studies on dietary choices leading to obesity have focused overwhelmingly on the sugar and fat content of snacks, fast foods, beverages, and confectionery. Epidemiologic studies have linked diets composed of fats and sweets, potatoes, and refined grains with higher glycemic indexes and a higher risk of obesity and type 2 diabetes. Obese patients were accordingly advised to replace fats and sweets with a more prudent dietary pattern characterized by a high intake of fruit, vegetables, whole grains, poultry, and fish. Among public health measures for the prevention of obesity are the need to restrict the consumption of energy-dense snacks and sugar-sweetened soft drinks and to increase the consumption of whole grains and energy-dilute vegetables and fruit. The inverse relation between energy density and energy cost suggests that “obesity-promoting” foods are simply those that offer the most dietary energy at the lowest cost. Given the differential in energy costs between energy-dense and energy-dilute foods, the advice to replace fats and sweets with fresh vegetables and fruit may have unintended economic consequences for the consumer.

associations between higher household incomes and higher quality diets were also obtained in studies conducted in Canada, France, the United Kingdom, and other countries of the European Union. Women reporting food insecurity had lower quality diets. Mean HEI scores in the 1988–1994 NHANES III data set were 58.8 for women in food-insecure households compared with 62.7 for women in food-sufficient households.

guidelines (7.4 compared with 8.2). Women in food-insecure households consumed the same amount of energy as did women in food-sufficient households (1959 compared with 1868 kcal/d). Although the energy density of the diet was not calculated, energy-dense diets are those that contain the least fruit, vegetables, and milk. Limited economic resources appeared to have an adverse effect, not so much on dietary energy, but rather on the overall quality and, potentially, the energy density of the diet.

mass index (BMI) and waist-to-hip ratio at age 26 years decreased. These associations remained significant after controlling for infant health and after adding statistical controls for adult SES. Upward mobility did not eliminate the effect of low SES in childhood on adult BMI, but did modify its effect on waist-to-hip ratio. Poulton et al. state, ‘‘Research now needs to identify the key mechanisms that bring about this longitudinal association’’ between low SES in childhood and adult obesity. Our group has conducted research on food insecurity as it is experienced in food-rich countries such as the US and its relation to obesity in adult women. Food insecurity is defined as occurring ‘‘whenever the availability of nutritionally adequate and safe foods or the ability to acquire acceptable foods in socially acceptable ways is limited or uncertain.” Several teams of investigators have found a significant association between food insecurity and increased risk of overweight and obesity in women in cross-sectional studies. In the one longitudinal study covering the time period from early pregnancy until 2 years postpartum, food insecurity at the beginning of pregnancy was positively associated with major weight gain at 2 years postpartum but only in the women who were initially obese. This finding could be interpreted as suggesting that both food insecurity and obesity are influenced by a common factor. We speculated that this common factor was the experience of poverty associated food insecurity in early childhood and the eating practices and attitudes resulting from food insecurity. In a recent study of 25 overweight and obese poor white women, eating in childhood as a way to keep your mind off of your problems was mentioned as a factor contributing to weight problems in the adult years.

p hys i ca l e ffe c ts

a case study of the influence of early experiences on current eating patterns For some women, contemporary eating patterns associated with childhood food deprivation, particularly overeating, may evolve over time to become a more generalized response to negative emotional states. Emeline related that as a child,

“When I get nervous I’ll eat a lot, I’ll eat a lot. And then when I’m not nervous and I’m calm, I’m just, I’m so stuffed from eating so much that I don’t want to eat.”

When food became available again after a period of food scarcity, Emeline would eat till “I had such a big stomachache. And then I would sleep. I remember that.” Over the course of her interviews Emeline realized that her current pattern of food binges bore some similarity to her childhood eating behavior. In childhood, a pattern of eating had been imposed upon her: she had at times been forced to go without food because her family had been food insecure; she had gorged herself when food became available. In adulthood, Emeline had endured additional food-insecure periods. Although by the third wave of data collection, Emeline was food secure, she had been food insecure at the beginning of the study. In adulthood, there were again fluctuations in her eating, with the current ebb and flow of her food intake relating to her emotional state. Emeline recognized that, “When my sister and I were growing up there were times we went to bed with nothing. And it wasn’t my mother’s fault. She worked hard.”


l on g t erm imp l ic at ion s f or eat in g pat t ern s a n d body w eight

Her mother’s recent illness had triggered a period of both nervousness and eating. Emeline continued:

“Eating, eating. Oh, yeah! ...I just know I got addicted to cheesecake and all that stuff. I did. It, oh, it was so bad!

When my mom was sick and, oh, that was, I mean I craved

cheesecake. I’m glad I got out of that one. So now I’m tryin’

to eat balanced, you know, the balanced meals and [sighs].

I just, when you get nervous you don’t think, you just wanna [she imitates eating] rrr, rrr, rrr!”

Emeline’s eating pattern from earlier in her life persisted, even though she was not currently food insecure. Her periodic overeating, now presumably for emotional comfort, echoed her overeating till I had such a big stomachache that had comforted her in childhood. “I’ll eat everything that I can, that’s not good for me. Junk food. Not can-, not candy. Like potato chips, dip, soda. I’ll go downstairs and buy a bunch of soda. Regular soda. And then I’ll cook and I’ll eat, and, you know, it’s not, it’s not healthy. I mean, so many people, what’s the name of it? Binge. Food binges. I know that I’ve had a problem with that for a long time. I have an eating, I do have an eating disorder, so. But I don’t, you know, in order to lose weight I don’t go in the bathroom and make myself sick, you know? I really try to cut back and exercise. I have them [food binges] a lot now. I, I think it’s because I get so nervous. At least two times a week. And then the rest of the time I’ll eat either, you know, a little bit or less than what I should eat for a meal. Because I’m not hungry.”

Food deprivation in childhood and associated attitudes and behaviors towards food are one possible mechanism for explaining the association between childhood poverty and adult obesity.


l on g t erm imp l ic at ion s f or eat in g pat t ern s a n d body w eight

conclusions Several measures of growing up in disadvantaged socioeconomic circumstances were significantly associated with increased likelihood of being overweight or obese in adulthood. Further, the women who were categorized as growing up in low SES families described their povertyassociated experiences with food deprivation in early life. Some explicitly made the link between their past experiences and contemporary attitudes and behavior toward food. Second, the findings or hypotheses that emerged from the qualitative analyses provide insight into potential foodrelated mechanisms between childhood food deprivation and adult obesity. Current food shopping, preparation, and eating practices were influenced by childhood experiences of food deprivation among the women in this sample. Some women were highly motivated and made great effort to have an adequate household food supply in adult life because of their earlier experiences of food deprivation. Women also described repercussions of their earlier experiences that we interpreted as somewhat negative from a nutritional perspective, including eliminating economical and nutritious foods from their current diets and an emotional attachment to food and food availability. Emotional attachments and extreme excitement about having enough of the preferred foods available in the home led to overeating among some in the sample and increased their risk of overweight and obesity. Polivy (1996) notes the link between the experiences of food deprivation and overeating when food becomes available is well established.â&#x20AC;&#x192;


Psychological Effects Stressful social circumstances, particularly constrained economic resources, have been linked to behavioral problems in young children and to symptoms of depression and anxiety in mothers. Reducing the risk of these mental health problems in families might be possible if specific stressors that could feasibly be addressed by social policy were identified. Qualitative research has shown that food insecurity, defined as a limited or uncertain availability of nutritionally adequate and safe food resulting from constraints in economic resources is a particular form of material deprivation that can stress mothers and their children. Food insecurity is also a stress that may potentially be relieved by existing federal food assistance programs such as the Food Stamp Program or the Special Supplemental Nutrition Program for Women, Infants, and Children, but the impact of such programs is difficult to study.


Food insecurity has been shown to cause stress in mothers and their children.

anxiety, depression, hyperactivity, and not getting along with peers. However, some of these studies did not control for other socioeconomic stressors, and each of these studies, expect for one, involved only low-income families living in 1 or 2 cities. The single study with a more diverse sample of US families did not use standardized measures of children's behavior problems and did not assess preschool-aged children, who may be particularly vulnerable to the stress arising from food insecurity. Furthermore, none of these studies measured food insecurity using the US Household Food Security Survey Module, now considered the standard for assessing household food security. Although there have been large studies examining the relationship between food security and mental health in mothers, none have included data on children's mental health. Using data on urban, 3-year-old children and their mothers from a recent US birth-cohort study, we examined the association of maternal food insecurity with depression and anxiety in mothers and with behavior problems in their preschool-aged children. In addition, we determined whether maternal depression and anxiety explained any of the association between maternal food insecurity and child behavior problems.

objectives We sought to determine if the prevalence of depression and anxiety in mothers and the prevalence of behavior problems in preschool-aged children are more common when mothers report being food insecure.

Mental health problems in mothers and children are more common when mothers are food insecure, a stressor that can potentially be addressed by social policy.

conclusions Using a recent birth-cohort sample drawn from 18 large US cities, we have shown that the prevalence of behavior problems among 3-year-old children increases with the level of maternal food insecurity, as does the 12-month prevalence in mothers of an MDE and GAD. This study is unique in its examination of the relationship between food security and the mental health of both mothers and children in a large, population-based sample of families from multiple US cities. It has the further strengths of using well-validated measures of both food security and mental health and controlling for multiple covariates. Certain stresses early in life, such as emotional, physical, or sexual abuse, increase the risk of later mental health problems, possibly by altering brain neurochemistry and morphology Food insecurity may be a form of early life stress that can also have long-term health implications. Studies of variable foraging demand suggest that the stress associated with food insecurity might express itself through neural circuits involving corticotropin-releasing factor. These are the same neural mechanisms by which other early life stresses are hypothesized to result in a distinct biological subtype of adult depression. Future studies should examine whether household food insecurity increases a child's susceptibility to later mental health problems. Social policy can address food insecurity more directly than it can address many other early-life stresses, and doing so can enhance the well being of both mothers and children.


Attachment and Mental Proficiency in Toddlers

intro We lack research in which a fully articulated model is examined asking whether there are direct as well as indirect pathways between food security and child outcomes. We need a model that empirically tests the linkages across all of the components simultaneously while controlling for a range of potentially confounding variables. This is the purpose of the current analyses.

hypotheses Food insecurity during infancy will be directly associated with less positive social and emotional and cognitive outcomes for children during toddlerhood. There will be indirect effects of food insecurity during infancy on social, emotional, and cognitive outcomes during toddlerhood. We hypothesize that food insecurity may increase maternal depression, and this will in turn influence parenting behaviors and cognitively stimulating activities in the home, which will subsequently influence child outcomes.

objectives This study examined the associations between household food security during infancy and attachment and mental proficiency in toddlerhood.


p s ycho l o gi c al e ffe c ts

Methods Data from a longitudinal nationally representative sample of infants and toddlers from the Early Childhood Longitudinal Study—9-month (2001–2002) and 24-month (2003–2004) surveys were used. At 9 months, 10,688 parent interviews and 10,221 child assessments were completed. Data from the 9-month wave (including retrospective data from the previous calendar year) were used to categorize children in households according to their levels of food security. The 9-month study was also used to examine the pathways through which food insecurity influences social and emotional and cognitive development. Longitudinal analyses help to increase confidence that the relationships examined are causal in nature. Therefore, the child outcomes that are examined are derived from the 24-month data collection wave. Structural equation modeling was used to examine the direct and indirect associations between food insecurity at 9 months, and attachment and mental proficiency at 24 months. The outcome variables measured were social and emotional well-being, and cognitive and mental proficiency. The primary predictor was household food security. The mediators were cognitively stimulating activities, maternal depression, and parenting practices. The control variables included mother and father’s individual characteristics, household level characteristics, child characteristics, and child care characteristics.

The results underscore the importance of programs and policies seeking to assure that families with infants have sufficient nutrition, available predictably. Such efforts have the potential to affect two generations: both mothersâ&#x20AC;&#x2122; psychological well-being and positive behaviors with their infants, and the childrenâ&#x20AC;&#x2122;s development over the first two years.

conclusions The results of this study support the perspective that food security affects children’s development very early. More specifically, greater food insecurity, measured at nine months in a nationally representative sample of families with infants, predicted insecure child attachment and less advanced mental proficiency at 24 months, operating not directly but through food insecurity’s influence on maternal depression and in turn on parenting practices. These results add to the earlier findings of the present research group indicating that food security also has implications for the overall health and weight of toddlers. Together, these results provide substantial support for the view that food security begins to influence children’s development at very young ages.

policy implications Work such as the present study can help direct policy and program efforts, for example, potentially pointing to the need to address not only the sufficiency of food resources, but also maternal depression and parenting behavior. The present study indicates that food insecurity is present in over 10% of US households with infants. In addition, our findings indicate that food insecurity affects children’s development very early in life. Together with our earlier results, the present study indicates that the effects of food insecurity, operating through maternal mental health and parenting behaviors, predict child outcomes in the two major domains examined: social and emotional development and cognitive development. The findings raise the possibility that in families that have already been experiencing food insecurity, it may be beneficial to address not only the adequacy and reliability of food resources, but also maternal depression and less positive parenting behavior that may have developed in response to concerns about the adequacy of food.


Mental Disorders in Teenagers


men ta l d is ord ers in t eena gers

intro More than one in five U.S. youth younger than 18 years lived in a family with an income below the federal poverty line in 2010. Poverty is defined by the federal government as inadequate income relative to estimated need based on family size, and is consistently associated with increases in internalizing and externalizing problems in children and adolescents. However, little research has examined whether poverty specifically increases risk for youth psychopathology or whether other dimensions of socioeconomic status (SES) explain this relation. On the one hand, poverty might influence mental health as a result of deprivation in resources needed to sustain health, including food and shelter. This sort of material deprivation typically occurs in the context of extreme poverty and may be associated with psychopathology risk. On the other hand, prior research has found a linear association between family income and youth psychopathology, with lower levels of income related to a higher risk of anxiety, depression, and behavior disorders across the entire income distribution. Food insecurity, the inability to purchase adequate amounts of food to meet basic needs is one marker that may better capture severe material deprivation. In the United States, food insecurity is most commonly experienced by families living in poverty and those that have experienced recent economic stressors such as unemployment or loss of food stamps. Food insecurity is associated with adverse health outcomes in children and adolescents, including vitamin and nutrient deficiency, developmental delay, hospitalization, and overweight status, even after adjustment for family income. Food insecurity is also associated with symptoms of anxiety and depression and externalizing problems in children, although the authors are unaware of previous research examining the relation between food insecurity and youth mental disorders.

objectives To examine whether food insecurity is associated with pastyear DSM-IV mental disorders after controlling for standard indicators of family socioeconomic status (SES) in a U.S. national sample of adolescents.

A 1-standard deviation increase in food insecurity was associated with a 14% increase in the odds of past-year mental disorder, even after controlling for extreme poverty.

Food insecurity is associated with a wide range of adolescent mental disorders independently of other aspects of SES. Expansion of social programs aimed at decreasing family economic strain might be one useful policy approach for improving youth mental health.

their reach and uptake to assist families struggling to anxiety, behavior, and substance disorders after controlling for numerous other indicators of SES, such that a one standard deviation increase in food insecurity was associated with 14% greater odds of past-year mental disorder in adolescents. Importantly, food insecurity was more strongly related to adolescent mental disorders than traditional SES measurements, including parental education and income. The associations between food insecurity and adolescent mental disorders were not attenuated even when extreme poverty was controlled, suggesting that this aspect of material deprivation reflects a form of economic strain that has more pernicious consequences for adolescent mental health than simply living in a family with a very low income. Prior research has indicated that difficulty paying for the necessities of living is associated with poor physical health over and above the effects of income. Food insecurity was associated with mood disorders more strongly in adolescents living in families with low household income and high relative deprivation, consistent with prior research reporting the strongest associations between food insecurity and adverse physical health in low-income families. Together these findings suggest that extreme material deprivation not only is associated with behavioral problems in children, but also may be a determinant of mental disorders. The authors cannot determine in this study whether inadequate access to food specifically is related to mental disorders or whether these findings simply reflect an association of deprivation in access to basic necessities more broadly with adolescent psychopathology. This issue warrants further investigation in future research.


Conclusion Food insecurity, the inability to provide enough food for a healthy and active lifestyle, is a complicated and serious problem. Its effects extend beyond hunger to the physical and psychological aspects of individuals who experience food insecurity. Those who are food insecure are more likely to be obese, due to the high energy density of inexpensive foods. Dealing with food insecurity can also lead to a range of psychological effects, including attitude toward food, parental depression, child development, and behavior problems. Since the issue of food insecurity extends far beyond simply having enough food to eat, it is important that those who have the means to help are aware of the situation. Clearly understanding the problem and its effects is the first step to helping the impoverished. Now we need to implement programs that provide inexpensive and nutritious food to people of low income, and educate them about the importance of eating healthy.


The effects of food insecurity extend beyond hunger to physical and psychological aspcets of life.
