Almost no previous research has examined the impact of the US Department of Agriculture’s (USDA) Summer Food Service Program and related Seamless Summer Option, which provide meals and snacks to low-income children over the summer. The present study investigated whether geographic accessibility of summer meals programme sites (a proxy for programme participation) was associated with food insecurity for low-income households.

The study used data from the California Health Interview Survey (CHIS) and administrative data on summer meals sites in California. Geocoding was used to calculate driving time between CHIS households and nearby summer meals sites. Geographic accessibility was measured using a gravity model, which accounted for the spatially distributed supply of and demand for summer meals. Food insecurity and very low food security were measured using a standard six-item measure from the USDA.

Geographic accessibility was not associated with food insecurity. However, geographic accessibility was associated with a significantly lower probability of very low food security in the full sample and among households with younger children and those living in less urban areas.

The USDA’s summer meals programme may be effective at reducing the most severe form of food insecurity for low-income households with children. Expanding the number of summer meals sites, the number of meals served at sites and sites’ hours of operation may be effective strategies to promote nutritional health over the summer months.

The present study is the first to use nationally representative data to compare rates of food insecurity among households with veterans of the US Armed Forces and non-veteran households.

We used data from the 2005–2013 waves of the Current Population Survey – Food Security Supplement to identify rates of food insecurity and very low food security in veteran and non-veteran households. We estimated the odds and probability of food insecurity in veteran and non-veteran households in uncontrolled and controlled models. We replicated these results after separating veteran households by their most recent period of service. We weighted models to create nationally representative estimates.

Nationally representative data from the 2005–2013 waves of the Current Population Survey – Food Security Supplement.

US households (n 388 680).

Uncontrolled models found much lower rates of food insecurity (8·4 %) and very low food security (3·3 %) among veteran households than in non-veteran households (14·4 % and 5·4 %, respectively), with particularly low rates among households with older veterans. After adjustment, average rates of food insecurity and very low food security were not significantly different for veteran households. However, the probability of food insecurity was significantly higher among some recent veterans and significantly lower for those who served during the Vietnam War.

Although adjusting eliminated many differences between veteran and non-veteran households, veterans who served from 1975 and onwards may be at higher risk for food insecurity and should be the recipients of targeted outreach to improve nutritional outcomes.

Adverse childhood experiences, including abuse, neglect and household instability, affect lifelong health and economic potential. The present study investigates how adverse childhood experiences are associated with food insecurity by exploring caregivers’ perceptions of the impact of their childhood adversity on educational attainment, employment and mental health.

Semi-structured audio-recorded in-person interviews that included (i) quantitative measures of maternal and child health, adverse childhood experiences (range: 0–10) and food security using the US Household Food Security Survey Module; and (ii) qualitative audio-recorded investigations of experiences with abuse, neglect, violence and hunger over participants’ lifetimes.

Households in Philadelphia, PA, USA.

Thirty-one mothers of children <4 years old who reported low or very low household food security.

Twenty-one caregivers (68 %) reported four or more adverse childhood experiences, and this severity was significantly associated with reports of very low food security (Fisher’s exact P=0·021). Mothers reporting emotional and physical abuse were more likely to report very low food security (Fisher’s exact P=0·032). Qualitatively, participants described the impact of childhood adverse experiences with emotional and physical abuse/neglect, and household substance abuse, on their emotional health, school performance and ability to maintain employment. In turn, these experiences negatively affected their ability to protect their children from food insecurity.

The associations between mothers’ adverse experiences in childhood and reports of current household food security should inspire researchers, advocates and policy makers to comprehensively address family hardship through greater attention to the emotional health of caregivers. Programmes meant to address nutritional deprivation and financial hardship should include trauma-informed approaches that integrate behavioural interventions.
