To evaluate the secondary impact of a multilevel, child-focused, obesity intervention on food-related behaviours (acquisition, preparation, fruit and vegetable (FV) consumption) on youths’ primary caregivers.

B’More Healthy Communities for Kids (BHCK) group-randomized controlled trial promoted access to healthy foods and food-related behaviours through wholesaler and small store strategies, peer mentor-led nutrition education aimed at youths, and social media and text messaging targeting their adult caregivers. Measures included caregivers’ (n 516) self-reported household food acquisition frequency for FV, snacks and grocery items over 30 d, and usual FV consumption in a sub-sample of 226 caregivers via the NCI FV Screener. Hierarchical models assessed average treatment effects (ATE). Treatment-on-the-treated-effect (TTE) analyses evaluated correlation between behavioural change and exposure to BHCK. Exposure scores at post-assessment were based on self-reported viewing of BHCK materials and participating in activities.

Thirty Baltimore City low-income neighbourhoods, USA.

Adult caregivers of youths aged 9–15 years.

Of caregivers, 90·89 % were female; mean age 39·31 (sd 9·31) years. Baseline mean (sd) intake (servings/d) was 1·30 (1·69) fruits and 1·35 (1·05) vegetables. In ATE, no significant intervention effect was found on caregivers’ food-related behaviours. In TTE, each point increase in BHCK exposure score (range: 0–6·9) increased caregivers’ daily fruit consumption by 0·2 servings (0·24 (se 0·11); 95 % CI 0·04, 0·47). Caregivers reporting greater social media exposure tripled their daily fruit intake (3·16 (se 0·92); 95 % CI 1·33, 4·99) and increased their frequency of unhealthy food purchasing v. baseline.

Child-focused community-based nutrition interventions may also benefit family members’ fruit intake. Child-focused interventions should involve adult caregivers and intervention effects on family members should be assessed. Future multilevel studies should consider using social media to improve reach and engage caregiver participants.

The present study was conducted to examine barriers to and facilitators of serving reduced-sodium meals (RSM) in worksite cafeterias.

We conducted in-depth interviews with key stakeholders in food catering companies.

Food catering companies at various customer sites in South Korea.

A total of nineteen interviews with twenty-five participants from ten catering companies were conducted. Sixteen on-site dietitians and nine managers from the catering companies’ headquarters participated in the interviews.

Four main themes emerged from the interviews. First, key stakeholders’ psychosocial characteristics (perception, intention and knowledge) are important in serving RSM in worksite cafeterias. Second, skills and techniques related to measuring sodium content and preparing RSM were emphasized by the interviewees. Third, the lack of various delicious low-sodium menus is a barrier to serving RSM. Lastly, a number of environmental factors were addressed, which include social support for reduced-sodium diets (a facilitator) and pressure to maintain profit margins (a barrier), that contribute to serving meals with less salt. Based on these factors, various recommendations for future sodium reduction policies and programmes were suggested.

It is important to implement population-wide sodium reduction as a means of preventing CVD and stroke. The study provided important facilitators of and barriers to serving RSM in worksite cafeterias, which could be helpful in developing environmental interventions that promote low-sodium diets.

To evaluate the implementation of a controlled, 6-week, environmental and educational intervention to improve dietary intake and body composition, and to study the association of implementation fidelity with diet and body composition outcomes.

A process evaluation documented participation, dose of nutrition education delivered, participant satisfaction, fidelity and completeness of the food environment intervention implementation, and context through observations and interviews with staff and residents. Intervention sites were scored and categorized as high or low participation and implementation and compared on essential elements of the food environment and on diet and body composition outcomes.

Six urban residential drug-treatment facilities in Upstate New York.

Fifty-five primarily black and white men in residential drug-treatment programmes.

Participants were exposed to 94 % and 69 % of the educational and environmental elements, respectively. High implementation sites were significantly more likely to provide water and 100 % juice, offer fruit or vegetable salad, offer choices of fruits and vegetables, and limit fried foods. Mixed-model analysis of covariance revealed that participants in the high participation and implementation sites reported greater reductions in total energy, percentage of energy from sweets, daily servings of fats, oils and sweets, and BMI over the intervention period. Participants in low participation and implementation sites reported greater reductions in percentage of energy from fat. Differential implementation of environmental elements limited the intervention impact.

These findings document the contribution of changes in eating environments to facilitate dietary behaviour change in community residential substance-abuse settings.
