This article examined whether participation in the Supplemental Nutrition Assistance Program (SNAP) produced changes to adult and child health and health care utilisation during a period of economic recession.

Instrumental variables analysis relying on variation in state SNAP policies to isolate exogenous variation in household SNAP participation.

Nationally representative data on child and adult health from the 2008 to 2013 National Health Interview Survey.

Participants were 92 237 adults and 45 469 children who were either eligible for SNAP based on household income and state eligibility rules or were low income but not eligible for SNAP benefits.

For adults, SNAP participation increased the probability of reporting very good or excellent health, and for both adults and children, reduced needing but having to go without dental care or eyeglasses. The size of these benefits was especially pronounced for children. However, SNAP participation increased the probability of needing but not being able to afford prescription medicine, and increased psychological distress for adults and behavioural problems for children under age 10.

SNAP’s benefits for adult health and improved access to dental and vision care for adults and children suggest benefits from the program’s expansions during the current COVID-induced crisis. Predicted negative effects of SNAP participation suggest the need for attention to program and benefit structure to avoid harm and the need for continued research to explore the causal effects of program participation.

The current study aimed to (i) describe racial/ethnic disparities in household food and beverage purchases among participants and non-participants in the Supplemental Nutrition Assistance Program (SNAP) and (ii) examine longitudinal associations between SNAP participation and purchases by race/ethnicity.

To describe disparities, we estimated sociodemographic-adjusted mean purchases of seven unhealthy food and beverage groups (e.g. junk food, sugar-sweetened beverages) and four nutrients (e.g. sugar, Na) among white, black and Hispanic SNAP-participating and non-participating households. To examine longitudinal associations, we used multivariable linear regression with household fixed effects.

USA, 2010–2014.

Food and beverage purchases among low-income (≤250 % federal poverty line) US households (n 30 403) participating in the Nielsen Homescan Panel.

Among non-participants, there were significant black–white disparities (i.e. differences favouring white households) in households’ adjusted mean purchases of processed meat, sweeteners, sugar-sweetened beverages, energy and Na. These disparities persisted among SNAP participants. In contrast, the only significant Hispanic–white disparity among non-participants was for Na purchases; this disparity was reduced in magnitude and no longer significant among SNAP-participating households. Additionally, Hispanic households purchased less energy from junk foods than white households, regardless of SNAP status. In longitudinal models accounting for household fixed effects, SNAP participation was associated with increased energy purchased among black households. No other significant longitudinal associations between SNAP and purchase outcomes were observed.

SNAP may not be meeting its potential to improve food and beverage purchases or reduce disparities. Research is needed to identify strategies for ensuring nutritious purchases across all racial/ethnic groups.

The present study examines the connection between the timing and size of Supplemental Nutrition Assistance Program (SNAP) benefits and the occurrence of emergency room (ER) visits for hypoglycaemia, a condition that is highly sensitive to short-term changes in nutritional intake.

We used administrative data from Missouri SNAP and Medicaid to identify the timing of issuance and the benefit size of SNAP and the timing of ER claims for hypoglycaemia. We estimated the probability of submitting an ER claim for hypoglycaemia as a function of the calendar week, SNAP benefit week and the size of the SNAP benefit in models that controlled for individual demographic characteristics.

Missouri SNAP caseload from January 2010 to December 2013 linked to adult Medicaid claims data for the same time period.

ER claims submitted to Medicaid (n 6 508 061).

The results indicated no evidence of a SNAP benefit cycle or monthly cycle to ER claims for hypoglycaemia. However, the analysis did find that ER claims for hypoglycaemia are related to the size of the SNAP benefit.

These results suggest that more generous SNAP benefits help households avoid nutritional fluctuations in the quality and quantity of food that might result in low blood sugar, thus necessitating fewer ER visits for hypoglycaemia.

In the present analysis, we seek to establish a relationship between time spent on food-related activities and food security status as well as between time spent on these activities and Supplemental Nutrition Assistance Program (SNAP, formerly called the Food Stamp Program) participation and benefit level.

After matching similar households using Coarsened Exact Matching, we estimate the relationship between food-related time, food insecurity and SNAP participation and benefit level using a comprehensive data set that combines two subsets of the Current Population Survey from years 2004–2010: the Food Security Supplement and the American Time Use Survey.

City, suburban and rural areas of the USA.

Non-institutionalized US population over the age of 15 years. Total sample size is 10 247 households.

In single households, food insecurity and SNAP participation are associated with 20 % more time in meal preparation and 13 % less time eating. Similarly, in married households, SNAP participation and benefit level are associated with 32 % less time in meal preparation while food insecurity is associated with 17 % less time eating and 14 % less time in grocery shopping.

A significant relationship exists between time spent on food-related activities and food insecurity and SNAP. This implies that federal and state government may need to consider the time constraints many low-income households face when reforming food assistance programmes.

To determine factors associated with Food Stamp Program (FSP) participation in a potentially eligible California population.

The California Women’s Health Survey is an on-going annual telephone survey that collects data about health-related attitudes and behaviours from a randomly selected sample of women. Statistical procedures included χ2 and logistic regression.

California, USA, from 2002 to 2004.

A total of 527 FSP female participants and 1405 potentially eligible non-participant females, aged 18 years and older.

The following characteristics remained independently and positively related to FSP participation: single mother with children; unemployed; on welfare; on WIC (the Special Supplemental Nutrition Program for Women, Infants, and Children); and US-born. Women under 25 years and those over 54 years were less likely to participate than women aged 25–54 years. Hispanic/Latino ethnicity was also negatively related to participation. Over 42 % of potentially eligible non-participants cited ‘don’t need them’ as the reason for not applying for FSP, but 34·9 % either do not think they are eligible or do not know how to apply. Potentially eligible non-participants who cite ‘don’t need them’ as a reason for not applying are less likely to be food insecure, to have inadequate income and to use alternative emergency aid, compared to women citing all other reasons. The highest level of need is among those who cite worry about citizenship or stigma as reasons for not applying.

Strategies to increase participation in FSP should incorporate messages that change the public’s perception of the programme, in addition to simplifying the application process, raising awareness of eligibility criteria and improving customer service.
