Do Food Stamps Without Education Improve the Nutrient Intake of Recipients?:

Perceptions of a food benefit programme that includes financial incentives for the purchase of fruits and vegetables and restrictions on the purchase of foods high in added sugar

OBJECTIVE

To report perspectives of participants in a food benefit programme that includes foods high in added sugar (FAS) restrictions and FAS restrictions paired with fruits and vegetables (F/V) incentives.

DESIGN

Randomised experimental trial in which participant perspectives were an exploratory study outcome.

SETTING

Participants were randomised into one of three Supplemental Nutrition Assistance Program (SNAP)-like food benefit programme groups: (1) restriction: not allowed to buy FAS with benefits; (2) restriction paired with incentive: not allowed to buy FAS with benefits and 30 % financial incentive on eligible F/V purchased using benefits; or (3) control: same food purchasing rules as SNAP. Participants were asked questions to assess programme satisfaction.

PARTICIPANTS

Adults in the Minneapolis-St. Paul, MN metropolitan area, eligible for but not currently participating in SNAP who completed baseline and follow-up study measures (n 254).

RESULTS

Among remaining households in each group, most found the programme helpful in buying nutritious foods (88·2 %-95·7 %) and were satisfied with the programme (89·1 %-93·0 %). Sensitivity analysis results indicate that reported helpfulness and satisfaction with the programme may in some instances be lower among the restriction and the restrictions paired with incentive groups in comparison to the control group.

CONCLUSIONS

A food benefit programme that includes restriction on purchase of FAS or restriction paired with a financial incentive for F/V purchases may be acceptable to most SNAP-eligible households with children.

Associations of food stamp participation with dietary quality and obesity in children

OBJECTIVE

To determine if obesity and dietary quality in low-income children differed by participation in the Supplemental Nutrition Assistance Program (SNAP), formerly the Food Stamp Program.

METHODS

The study population included 5193 children aged 4 to 19 with household incomes ≤130% of the federal poverty level from the 1999-2008 NHANES. Diet was measured by using 24-hour recalls.

RESULTS

Among low-income US children, 28% resided in households currently receiving SNAP benefits. After adjusting for sociodemographic differences, SNAP participation was not associated with a higher rate of childhood obesity (odds ratio = 1.11, 95% confidence interval [CI]: 0.71-1.74). Both SNAP participants and low-income nonparticipants were below national recommendations for whole grains, fruits, vegetables, fish, and potassium, while exceeding recommended limits for processed meat, sugar-sweetened beverages, saturated fat, and sodium. Zero percent of low-income children met at least 7 of 10 dietary recommendations. After multivariate adjustment, compared with nonparticipants, SNAP participants consumed 43% more sugar-sweetened beverages (95% CI: 8%-89%), 47% more high-fat dairy (95% CI: 7%, 101%), and 44% more processed meats (95% CI: 9%-91%), but 19% fewer nuts, seeds, and legumes (95% CI: -35% to 0%). In part due to these differences, intakes of calcium, iron, and folate were significantly higher among SNAP participants. Significant differences by SNAP participation were not evident in total energy, macronutrients, Healthy Eating Index 2005 scores, or Alternate Healthy Eating Index scores.

CONCLUSIONS

The diets of low-income children are far from meeting national dietary recommendations. Policy changes should be considered to restructure SNAP to improve children's health.

The Effects of Childhood SNAP Use and Neighborhood Conditions on Adult Body Mass Index

The disproportionate number of individuals who are obese or overweight in the low-income U.S. population has raised interest in the influence of neighborhood conditions and public assistance programs on weight and health. Generally, neighborhood effects and program participation effects have been explored in separate studies. We unite these two areas of inquiry, using the 1968–2005 Panel Study of Income Dynamics (PSID) to examine the long-term effects of childhood Supplemental Nutrition Assistance Program (SNAP) participation, neighborhood conditions, and the interaction of these two, on adult body mass index (BMI). Using sibling fixed-effects models to account for selection bias, we find that relative to children in other low-income families, children in SNAP-recipient households have higher average adult BMI values. However, the effects of childhood SNAP usage are sensitive to both residential neighborhood and age at receipt. For those growing up in advantaged neighborhoods, projected adult BMI is higher for children in SNAP-recipient households than for children in low-income, nonrecipient households. In contrast, for those growing up in less-advantaged areas, adult BMI differences between children in SNAP-recipient and those in low-income, nonrecipient households are small. SNAP usage during preschool years (0 to 4) has no impact on adult BMI scores. However, at later childhood ages, the time elapsed receiving SNAP income increases adult BMI values relative to a condition of low-income nonreceipt.

Is participation in food and income assistance programmes associated with obesity in California adults? Results from a state-wide survey

OBJECTIVE

Public assistance programmes may increase risk of obesity among adults. The current study assessed whether participation in the Supplemental Nutrition Assistance Program (SNAP; formerly the Food Stamp Program), Supplemental Security Income (SSI) or California Work Opportunities and Responsibilities to Kids (CalWorks) was associated with obesity, independent of socio-economic status and food insecurity.

DESIGN

A cross-sectional analysis of the 2007 Adult California Health Interview Survey. Outcome measures included BMI and obesity. Distribution of BMI and prevalence of obesity were compared by participation in each programme, using weighted linear and binomial regression models in which BMI or obesity was the outcome, respectively, and programme participation was the predictor.

SETTING

A population survey of various health measures.

SUBJECTS

Non-institutionalized adults (n 7741) whose household income was ≤130% of the federal poverty level.

RESULTS

The prevalence of obesity was 27.4%. After adjusting for sociodemographic characteristics, food insecurity and participation in other programmes, the prevalence of obesity was 30% higher in SNAP participants (95% CI 6%, 59%; P=0.01) than in non-participants. This association was more pronounced among men than women. SSI participation was related to an adjusted 50% higher prevalence of obesity (95% CI 27%, 77%; P<0.0001) compared with no participation. SNAP and SSI participants also reported higher soda consumption than non-participants of any programme. CalWorks participation was not associated with obesity after multivariable adjustment.

CONCLUSIONS

Participation in SNAP or SSI was associated with obesity independent of food insecurity or socio-economic status. The suggestion that these associations may be mediated by dietary quality warrants further investigation among low-income populations.

The art of grocery shopping on a food stamp budget: factors influencing the food choices of low-income women as they try to make ends meet

OBJECTIVE

Amidst a hunger-obesity paradox, the purpose of the present study was to examine the grocery shopping behaviour and food stamp usage of low-income women with children to identify factors influencing their food choices on a limited budget.

DESIGN

Focus groups, which included questions based on Social Cognitive Theory constructs, examined food choice in the context of personal, behavioural and environmental factors. A quantitative grocery shopping activity required participants to prioritize food purchases from a 177-item list on a budget of $US 50 for a one-week period, an amount chosen based on the average household food stamp allotment in 2005.

SUBJECTS

Ninety-two low-income women, with at least one child aged 9-13 years in their household, residing in the Twin Cities, Minnesota, USA.

RESULTS

Participants' mean age was 37 years, and 76% were overweight or obese (BMI> or =25.0 kg/m2). Key findings suggest that their food choices and grocery shopping behaviour were shaped by not only individual and family preferences, but also their economic and environmental situation. Transportation and store accessibility were major determinants of shopping frequency, and they used various strategies to make their food dollars stretch (e.g. shopping based on prices, in-store specials). Generally, meat was the most important food group for purchase and consumption, according to both the qualitative and quantitative data.

CONCLUSIONS

Efforts to improve food budgeting skills, increase nutrition knowledge, and develop meal preparation strategies involving less meat and more fruits and vegetables, could be valuable in helping low-income families nutritionally make the best use of their food dollars.
