Evaluation of California Department of Public Health’s three-year social marketing campaign (Be Better) to encourage healthy eating and water consumption among Supplemental Nutrition Assistance Program-Education (SNAP-Ed) California mothers. Andreasen’s social marketing framework was used to outline the development and evaluation of the campaign.

Quantitative, pre-post cross-sectional study with three cohorts nested within survey years. Generalised estimating equation modeling was used to obtain population estimates of campaign reach and changes in mothers’ fruit and vegetable (FV) consumption and facilitative actions towards their children’s health behaviours.

CalFresh Healthy Living (California’s SNAP-Ed).

Three separate cohorts of SNAP mothers were surveyed (pre, post) between 2016 and 2018 inclusive. A total of 2229 mothers (ages 18–59) self-identified as White, Latina, African American or Asian/Pacific Islander participated.

Approximately 82 percent of surveyed mothers were aware of the campaign as assessed by measures of recall and recognition. Ad awareness was positively associated with mothers’ FV consumption (R2 = 0·45), with the proportion of FV on plates and with behaviours that facilitate children’s FV consumption and limit unhealthy snacks and sugary drinks (βs ranged from 0·1 to 0·7).

The campaign successfully reached 82 percent of surveyed mothers. Positive associations between California’s Be Better campaign and targeted health behaviours were observed, although the associations varied by year and media channel (i.e. television, radio, billboards and digital). Most associations between ad awareness and outcomes were noted in years two and three of the campaign, suggesting that more than 1 year of campaign exposure was necessary for associations to emerge.

School-based CalFresh Healthy Living (CFHL) (California’s SNAP-Ed) interventions adapted to new learning environments necessitated by COVID-19. We examined the impact of these interventions on student diet and physical activity (PA) outcomes.

Quasi-experimental, two-group, pre-post.

California public schools with ≥50 % of students Free and Reduced Price Meal-eligible (nintervention = 47; ncomparison = 17).

Fourth- and fifth-grade students who completed the online Eating and Activity Tool for Students at pre and post (nintervention = 1087; ncomparison = 846 students).

Intervention students reported a significantly greater increase in consumption frequency of total fruit (by 0·16 times/d; P = 0·032), driven primarily by a greater increase in 100 % fruit juice (by 0·11 times/d; P = 0·007). Intervention students reported a significantly greater increase in total vegetable consumption frequency (by 0·45 times/d; P < 0·001) than comparison students. Specifically, intervention students reported increased, whereas comparison students reported decreased, consumption frequencies for starchy vegetables (0·05 v. −0·10 times/d, P < 0·001), salad/green vegetables (0·01 v. −0·11 times/d, P = 0·005) and beans (0·04 v. −0·03 times/d, P = 0·025). Consumption frequency of other vegetables decreased in both groups (−0·01 v. −0·09 times/d) but decreased more among comparison students (P = 0·048). No differences in pre-post change in PA outcomes were detected.

Findings suggest that despite COVID-19-related challenges necessitating programme modifications, CFHL interventions played a role in protecting student consumption of fruit and vegetables during the 2020–2021 school year. Therefore, it appears that school-based CFHL interventions can be a viable means of safeguarding student nutrition at a time when access to nutritious food and PA opportunities are hindered.

To examine the impact of Nutrition for Life (NFL), a goal-setting nutrition education program, on the knowledge, self-efficacy and behaviour of adults eligible for Supplemental Nutrition Assistance Program-Education.

NFL was developed using a 4-week goal-setting behavioural strategy focused on nutrition, physical activity and meal planning techniques. A quantitative repeated-measures design using self-reported data was collected at pre- and post-interventions and at 1-week and 1-month follow-ups.

Two Federally Qualified Health Centers in Philadelphia, PA, USA.

A total of ninety-eight participants enrolled in the intervention; the majority were women (80·2 %), Black/Non-Hispanic (75·0 %) and 45–54 year old (39·6 %).

Participants showed significant improvement in knowledge, self-efficacy and behaviour. Specifically, mean daily intake for vegetables increased by 0·31 cup (P < 0·05) and for fruits by 0·39 cup (P < 0·01) at 1-week follow-up. Participants also showed healthier behaviour at 1-month follow-up. Planning at least seven meals per week increased from 14·8 to 50 % (P < 0·01), completing at least 30 min of physical activity every day in the last week increased from 16·7 to 36 % (P < 0·01) and consuming water with all meals increased from 39 to 70·6 % (P < 0·01).

The implementation of a goal-oriented nutrition education program offers a promising approach at achieving positive behaviour change among SNAP-eligible adults.

To investigate the association of policy, systems and environmental factors with improvement in household food security among low-income Indiana households with children after a Supplemental Nutrition Assistance Program-Education (SNAP-Ed) direct nutrition education intervention.

Household food security scores measured by the eighteen-item US Household Food Security Survey Module in a longitudinal randomized and controlled SNAP-Ed intervention study conducted from August 2013 to April 2015 were the response variable. Metrics to quantify environmental factors including classification of urban or rural county status; the number of SNAP-authorized stores, food pantries and recreational facilities; average fair market housing rental price; and natural amenity rank were collected from government websites and data sets covering the years 2012–2016 and used as covariates in mixed multiple linear regression modelling.

Thirty-seven Indiana counties, USA, 2012–2016.

SNAP-Ed eligible adults from households with children (n 328).

None of the environmental factors investigated were significantly associated with changes in household food security in this exploratory study.

SNAP-Ed improves food security regardless of urban or rural location or the environmental factors investigated. Expansion of SNAP-Ed in rural areas may support food access among the low-income population and reduce the prevalence of food insecurity in rural compared with urban areas. Further investigation into policy, systems and environmental factors of the Social Ecological Model are warranted to better understand their relationship with direct SNAP-Ed and their impact on diet-related behaviours and food security.
