Family structure and child food insecurity.

OBJECTIVES: We examined whether food insecurity was different for children in cohabiting or repartnered families versus those in single-mother or married-parent (biological) families. METHODS: We compared probabilities of child food insecurity (CFI) across different family structures in 4 national data sets: the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), the Fragile Families and Child Wellbeing Study (FFCWS), the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K), and the Panel Study of Income Dynamics-Child Development Supplement (PSID-CDS). RESULTS: Unadjusted probabilities of CFI in cohabiting or repartnered families were generally higher than in married-biological-parent families and often statistically indistinguishable from those of single-mother families. However, after adjustment for sociodemographic factors, most differences between family types were attenuated and most were no longer statistically significant. CONCLUSIONS: Although children whose biological parents are cohabiting or whose biological mothers have repartnered have risks for food insecurity comparable to those in single-mother families, the probability of CFI does not differ by family structure when household income, family size, and maternal race, ethnicity, education, and age were held at mean levels.

Financial management skills are associated with food insecurity in a sample of households with children in the United States.

Food insecurity is one of the leading public health challenges facing children in the United States today. Reducing food insecurity and its attendant consequences requires an understanding of the determinants of food insecurity. Although previous work has greatly advanced our understanding of these determinants, the role of one of the oft-speculated important determinants of food insecurity, household financial management skills, has not been considered. To address this research lacuna, we use a recently conducted survey, the Survey of Household Finances and Childhood Obesity, that has information on specific financial management practices, impressions of financial management skills, and households' food insecurity. The sample included 904 households with children. Within this sample, 19.3% were food insecure and, for our central financial management skill variable, the mean value was 3.55 on a 5-point scale. Probit regression models estimated the probability of a household being food insecure as conditional on financial management skills and other covariates. We found a large and significant inverse relationship between a respondent's use of specific financial management practices and food insecurity and between a respondent's confidence in his or her financial management skills and food insecurity. That is, households with greater financial management abilities are less likely to be food insecure. This finding also holds when the sample is restricted to households with incomes <200% of the poverty line. These results suggest that improving households' financial management skills has the potential to reduce food insecurity in the United States.

Exceptional longevity: an introduction to the Iowa Centenarian Study.

The primary objective of the Iowa Centenarian Study is to further our understanding of determinants of exceptional longevity above and beyond health outcomes, particularly in rural environments. This introductory article provides a general overview of the study, its methodology and basic descriptive results. One hundred and fifty-two centenarians from a rural state participated in the study (average age was 101.6 years). Baseline data collection included questions on demographics, cognitive representation of being a centenarian, mental status, past family history, life events, activities of daily living, coping, physical health and health history, nutrition, exercise, personality, social support, mental health, economic status and perceptions, and fatigue. A subset of the baseline sample (n = 28) participated in a short-term longitudinal study that assessed stability and change in mental status, mental health, and activity. Four additional papers in this issue (Franke, Margrett, Heinz, & Martin, 2012; Garasky, Martin, Margrett, & Cho, 2012; Margrett, Hsieh, Heinz, & Martin, 2012; Martin, da Rosa, Margrett, Garasky, & Franke, 2012) will highlight substantive findings, including longitudinal analyses, in activities of daily living, economic status, mental status, and positive and negative affect.

Stability and change in affect among centenarians.

Much information is available about physical and functional health among very old adults, but little knowledge exists about the mental health and mental health changes in very late life. This study reports findings concerning positive and negative affect changes among centenarians. Nineteen centenarians from a Midwestern state participated in four assessments over a 6-month period. Positive and negative affect, as well as physical activity, financial resources, mental status, and health were assessed at baseline and during four consecutive time points. Mean individual growth curves suggested mean decreases in positive affect, but no changes were observed in negative affect. Physical activity, financial resources, and self-rated health were associated with growth-curve changes in affect. Centenarians with fewer resources were more likely to show decreases in positive affect. Surprisingly, physical activity and health were associated with increases in negative affect over time. The results suggest that continued activity, high levels of financial resources, and self-rated health are important components in affective states among very old adults.

Understanding perceptions of economic status among centenarians.

Centenarians are often concerned with outliving their accumulated resources. Yet, research consistently finds that older adults, despite low incomes, are more financially satisfied than younger adults. This "satisfaction paradox" has been attributed to psychological accommodation to poor financial circumstances and lower expectations. As a result, scholars differentiate between objective levels of need and subjective perceptions. Missing is an understanding of whether feeling economically secure is associated with physical, mental, and/or psychological well-being and whether it varies by institutionalization status. This study examined data from 152 centenarians who participated in the first wave of the Iowa Centenarian Study. Analyses examined six perceived economic status variables (sufficiency of financial resources, ability to meet expenses, finances compared to others, meeting needs, ability to purchase extras, and having enough money for the future) and measures derived from activities of daily living, the Short Portable Mental Status Questionnaire (Pfeiffer, 1975) and the Geriatric Depression Scale (Yesavage, Brink, Rose, Lum, Huang, Adey, et al., 1983). Findings indicated that most centenarians do not feel able to handle their finances, yet believe that they are doing relatively well financially. Perceived economic status was positively associated with ability to complete daily living activities, cognitive ability, and psychological well-being with results differing by institutional status. In the end, we agree with other scholars that these relationships are rarely simple and require future exploration.

Adolescent overweight and obesity: links to food insecurity and individual, maternal, and family stressors.

PURPOSE: A high proportion of adolescents living in low-income households in the United States are overweight or obese, food insecure, or exposed to high levels of individual, maternal, and family stressors. The aim of this paper was to identify the associations of food insecurity and the aforementioned stressors with an adolescent's propensity to be overweight or obese. We hypothesized that individual, maternal, and family stressors may exacerbate the relationship between food insecurity and adolescent overweight/obesity. METHODS: The sample included 1011 adolescents aged 10 to 15 years and their mothers in families with incomes below 200% of the poverty line from Wave 1 of the Welfare, Children, and Families: A Three-City Study (Three-City Study). RESULTS: A series of logistic regressions predicted the probability of an adolescent being overweight or obese. Overall, higher levels of individual stressors increased the probability of being overweight or obese for adolescents, whereas there was no direct association between food insecurity, maternal, or family stressors and overweight or obesity. The interaction of food insecurity and maternal stressors was significantly linked to the probability of being overweight or obese; more specifically, an increase in maternal stressors amplified a food insecure adolescent's probability of being overweight or obese. CONCLUSIONS: Policies addressing adolescent obesity should consider the benefits to reducing the individual stressors facing low-income adolescents and, for food insecure adolescents, the benefits to reducing their mothers' stressors.

Food insecurity is not associated with childhood obesity as assessed using multiple measures of obesity.

There has been extensive previous research examining the connection between obesity and food insecurity, 2 serious nutrition challenges facing low-income children in the US. All of this work used BMI to categorize a child as obese. Although BMI is one way to categorize the obesity status of a child, other measures have not been used to understand the connection between food insecurity and obesity. In response, this study used multiple measures of obesity taken from the 2001 to 2004 NHANES. The sample included 2516 children between the ages of 8 and 17 y in households with annual incomes <200% of the poverty line. Within this sample, 36.6% of children were in food-insecure households. The prevalence of obesity depended on the measure employed (BMI, waist circumference, triceps skinfold thickness, trunk fat mass, body fat), with prevalence rates ranging from 15.4 to 44.8%. Logistic regression models estimated the probability of a child being obese using multiple measures of obesity conditional on food-insecurity status and other covariates. The results indicated that food-insecure children were no more likely to be obese than their food-secure counterparts across all measures of obesity. This relationship held after controlling for other factors and examining subpopulations based on race/ethnicity, gender, and race/ethnicity and gender. These results suggest that efforts to alleviate food insecurity and childhood obesity will work independently.

Family stressors and child obesity.

Child obesity is a public health priority with numerous and complex causes. This study focuses on factors within the family, namely stressful experiences, which may be associated with child obesity. We examine data from the Child Development Supplement of the Panel Study of Income Dynamics for children in two age groups: 5-11 and 12-17 years old. Results from an ordered probit regression model of child weight categorizations (healthy weight, overweight, obese) indicate positive associations between a range of family stressors (lack of cognitive stimulation and emotional support in the household among younger children, and mental and physical health problems and financial strain in the household among older children) and child overweight and obesity. We discuss how public policies that reduce family stressors may, in turn, help reduce child obesity.

Food security, maternal stressors, and overweight among low-income US children: results from the National Health and Nutrition Examination Survey (1999-2002).

OBJECTIVE: A high proportion of children in the United States are overweight, suffer from food insecurity, and live in households facing maternal stressors. The objective of this article was to identify the associations of food insecurity and maternal stressors with childhood overweight among low-income children. We hypothesized that maternal stressors may exacerbate the relationship between food insecurity and child obesity. METHODS: The sample included 841 children (3-17 years old) and their mothers with incomes below 200% of the poverty line from the 1999-2002 National Health and Nutrition Examination Survey. Food insecurity was based on US Department of Agriculture protocol, maternal stressors were assessed from survey questions, and BMI was used to classify weight status. Probit regression models predicted the probability of a child being overweight or obese. RESULTS: In most specifications, there was no direct association between food insecurity or maternal stressors and overweight for children of any age. Among 3- to 10-year-olds, the interaction of food insecurity and maternal stressors was significantly linked to the probability of being overweight; more specifically, an increase in maternal stressors amplified a food secure child's probability of being overweight or obese. This result is robust to alternative specifications. However, these results were not found among 11- and 17-year-old youth. CONCLUSIONS: Younger children in food secure, low-income households in the United States who are experiencing higher levels of maternal stressors have a greater probability of being overweight than food insecure children. This finding was contrary to the hypothesis; 3 reasons for this are covered in the article. Those who create policies that address childhood obesity could consider the benefits to low-income children's well-being resulting from reducing their mothers' stressors. Because most children in the United States are food secure, these policies could have a profound impact on childhood overweight.

Child-specific food insecurity and overweight are not associated in a sample of 10- to 15-year-old low-income youth.

In the United States, 17% of children and adolescents are overweight and 20% live in a food insecure household. Previous studies examining the association between household food insecurity and overweight among children have been inconclusive but are limited insofar as they did not assess child-specific measures of food insecurity and overweight. In response, this study examined the association between food insecurity and child overweight status when these variables were measured for the same child using information on children (n = 1031) aged 10-15 y from the Three-City Study. Approximately 8% of the children were food insecure, whereas 50% were either at risk of overweight or overweight. Bivariate analyses indicated that there were no significant differences in the prevalence of at risk of overweight and overweight between food secure and food insecure children. Gender, race, and income showed similar patterns. Results from logistic regression analyses also indicated that the likelihood of being overweight or at risk of overweight was not significantly different for food secure and food insecure children. Although child-specific food insecurity was not associated with overweight in this sample of low-income children, food insecurity and overweight coexist among these low-income children, because approximately 25% of the food insecure children were overweight. Additional research is needed to explore the potential relationships between food insecurity and overweight and to better inform policy that attempts to address these issues among low-income households with children.
