A Youth-Leader Program in Baltimore City Recreation Centers: Lessons Learned and Applications

Perceptions and Impact of a Youth-led Childhood Obesity Prevention Intervention among Youth-leaders

Objective

To evaluate the impact of a youth-led nutrition intervention on youth-leaders themselves.

Design

Mixed methods, including: in-depth interviews and a quasi-experimental quantitative study comparing youth-leaders and nonparticipant comparison youth.

Analysis

Qualitative analysis using direct content analysis. Difference-in-differences analyses assessing quantitative program impact.

Results

Youth-leaders perceived that the intervention impacted themselves, the youth-participants, and their respective social networks. Youth-leaders experienced greater increases in intentions to eat healthfully (p=0.04), and greater decreases in support for healthy eating from their friends (p=0.01), than the comparison group.

Conclusions/Implications

Youth-leaders reported multiple levels of intervention impact, and increased intentions for healthy eating; however, additional research is needed to enhance impact on behavioral outcomes.

Themes in Train-the-Trainer Nutrition Education Interventions Targeting Middle School Students: A Systematic Review

Context-appropriate nutrition education interventions targeting middle school students have the potential to promote healthy dietary patters that may help prevent unnecessary weight gain at a point in childhood development when youth experience increasing agency over their food choices. The aim of this review was to identify and synthesize themes in train-the-trainer approaches, intervention content and delivery, and youth receptivity across teacher, mentor, and peer-led nutrition education interventions that targeted middle school-age youth in urban, primarily low-income settings. A systematic, electronic literature search was conducted in seven electronic databases, PubMed/Medline, CINAHL, ERIC, PsycINFO, Scopus, SPORTDiscus, and Cochrane CENTRAL, using fixed inclusion and exclusion criteria. A total of 53 papers representing 39 unique interventions were selected for data extraction and quality assessment. A framework synthesis approach was used to organize the interventions into six categories and identify themes according to whether the intervention was classroom-based or out-of-school-based and whether adults, cross-age peers or same-age peers delivered the intervention. Ten of the interventions contained multiple components such that they were included in two of the categories. The review findings indicated that trainings should be interactive, include opportunities to role-play intervention scenarios and provide follow-up support throughout intervention delivery. Interventions targeting middle school youth should include positive messaging and empower youth to make healthy choices within their specific food environment context.

Long-term effects of a peer-led asthma self-management program on asthma outcomes in adolescent peer leaders

OBJECTIVE

To examine the long-term effects of a peer-led asthma self-management program on urban adolescent peer leaders with asthma.

METHODS

This longitudinal study includes 51 adolescents (16-20 years) enrolled in an asthma self-management program implemented at a one-day camp as peer leaders. Study outcomes, including quality of life, asthma control, asthma knowledge, and attitudes toward asthma were collected for 15 months post-intervention. Mixed-effects models were conducted to estimate time effects, and effect sizes were calculated for each model.

RESULTS

Of 51 enrolled, 41 completed the training, of which 35 successfully participated in the camp program. A total of 17 peer leaders withdrew between enrollment and 15-months follow-up. Quality of life, asthma control, and knowledge significantly improved after peer leader training and remained elevated for 15 months, while significant improvement in attitudes emerged immediately after camp, in which they served as leaders, and sustained for 15 months.

CONCLUSION

This study demonstrates the long-term positive effects of a peer-led program on a wide range of asthma outcomes in urban adolescent peer leaders.

PRACTICE IMPLICATIONS

A peer-led approach to asthma education providing peer leaders with intense training and leadership experience can be effective and sustainable in improving asthma outcomes among urban adolescents.

Fidelity of a peer-led asthma self-management intervention and its attention control in a multisite study of urban adolescents

In this paper we compare the fidelity of a Peer-Led Asthma Self-Management Program for Adolescents (PLASMA) and its attention control. A randomized controlled trial involving two groups-the PLASMA group and the attention control group-was conducted between 2015 and 2018. Adolescents 12-17 years old (N = 259) in three cities in the United States received asthma self-management education implemented at a day camp, followed by bi-monthly, follow-up contact for 12 months. Thirty-five peer leaders and six adult educators implemented education sessions for the PLASMA and the attention control groups, respectively. The intervention was the peer-led delivery of the content instead of the educational content itself. This study compares the extent to which the education sessions and follow-up contacts were implemented in accordance with the study protocol by the peer and adult educators. Most topics on asthma knowledge and skills (85-95%) were delivered as intended at an adequate pace in both groups. Peer leaders missed more content in the psychosocial domain than adult educators-14% versus 0%, respectively (t = -3.7; p = .010). PLASMA participants reported high content and time fidelity for all education sessions (94% to 97.6%). Greater success in bimonthly follow-up contacts was reported in the attention control groups, with 4.6 ( ± 1.5) contacts on average compared to 2.6 (±2.02) in the PLASMA groups (t = 9.02; p < .001). Most components of the asthma self-management program were implemented with high fidelity in both groups. The relatively low fidelity in delivering psychosocial content and performing follow-up contacts in the PLASMA groups underscores the need for intensive training to enhance peer leaders' competency with managing these aspects of PLASMA to maximize fidelity. Peer leaders can implement asthma self-management educational components of the intervention with high fidelity similar to adult educators.

Implementation of B'More Healthy Communities for Kids: process evaluation of a multi-level, multi-component obesity prevention intervention

B'More Healthy Communities for Kids was a multi-level, multi-component obesity prevention intervention to improve access, demand and consumption of healthier foods and beverages in 28 low-income neighborhoods in Baltimore City, MD. Process evaluation assesses the implementation of an intervention and monitor progress. To the best of our knowledge, little detailed process data from multi-level obesity prevention trials have been published. Implementation of each intervention component (wholesaler, recreation center, carryout restaurant, corner store, policy and social media/text messaging) was classified as high, medium or low according to set standards. The wholesaler component achieved high implementation for reach, dose delivered and fidelity. Recreation center and carryout restaurant components achieved medium reach, dose delivered and fidelity. Corner stores achieved medium reach and dose delivered and high fidelity. The policy component achieved high reach and medium dose delivered and fidelity. Social media/text messaging achieved medium reach and high dose delivered and fidelity. Overall, study reach and dose delivered achieved a high implementation level, whereas fidelity achieved a medium level. Varying levels of implementation may have balanced the performance of an intervention component for each process evaluation construct. This detailed process evaluation of the B'More Healthy Communities for Kids allowed the assessment of implementation successes, failures and challenges of each intervention component.

A multilevel, multicomponent childhood obesity prevention group-randomized controlled trial improves healthier food purchasing and reduces sweet-snack consumption among low-income African-American youth

BACKGROUND

Consumption of foods and beverages rich in sugar remains high across all races and ages in the United States. Interventions to address childhood obesity and decrease sugar intake are needed, particularly in low-income settings.

METHODS

B'more Healthy Communities for Kids (BHCK) was a group-randomized, controlled trial implemented among 9-15-year olds in 30 low-income areas of Baltimore. We increased access to low-sugar foods and beverages at wholesalers and small food stores. Concurrently, we encouraged their purchase and consumption by children through youth-led nutrition education in recreation centers, in-store promotions, text messaging and a social media program directed at caregivers. Sugar consumption (sugar sweetened beverage (SSB), sweets) in youth was assessed pre- (n = 534) and post-intervention (n = 401) using the Block Kids Food Frequency Questionnaire. Purchasing of 38 healthier and 28 less healthier food/beverage varieties in the previous 7 days was assessed via self-report. Multilevel models at the community and individual levels were used. Analyses were stratified by age (younger: 9-12-year olds (n = 339) vs older: 13-15 (n = 170)). Models were controlled for child's sex, race, total daily caloric intake, and caregiver's age and sex.

RESULTS

Overall baseline mean healthier food purchasing was 2.5 (+ 3.6; min. 0, max. 34 items per week), and unhealthier food purchasing 4.6 (+ 3.7; 0-19 items per week). Mean intake at baseline for kcal from SSB was 176 (+ 189.1) and 153 (+ 142.5), and % of calories from sweets (i.e. cookies, cakes, pies, donuts, candy, ice cream, sweetened cereals, and chocolate beverages) was 15.9 (+ 9.7) and 15.9 (+ 7.7) in comparison and intervention youth, respectively. Intervention youth increased healthier foods and beverages purchases by 1.4 more items per week than comparison youth (β = 1.4; 95% CI: 0.1; 2.8). After the intervention, there was a 3.5% decrease in kcal from sweets for older intervention youth, compared to the control group (β = - 3.5; 95% CI: -7.76; - 0.05). No impact was seen on SSB consumption.

CONCLUSION

BHCK successfully increased healthier food purchasing variety in youth, and decreased % calories from sweet snacks in older youth. Multilevel, multicomponent environmental childhood obesity programs are a promising strategy to improve eating behaviors among low-income urban youth.

The Impact of a Multi-Level Multi-Component Childhood Obesity Prevention Intervention on Healthy Food Availability, Sales, and Purchasing in a Low-Income Urban Area

The multifactorial causes of obesity require multilevel and multicomponent solutions, but such combined strategies have not been tested to improve the community food environment. We evaluated the impact of a multilevel (operating at different levels of the food environment) multicomponent (interventions occurring at the same level) community intervention. The B’more Healthy Communities for Kids (BHCK) intervention worked at the wholesaler (n = 3), corner store (n = 50), carryout (n = 30), recreation center (n = 28), household (n = 365) levels to improve availability, purchasing, and consumption of healthier foods and beverages (low-sugar, low-fat) in low-income food desert predominantly African American zones in the city of Baltimore (MD, USA), ultimately intending to lead to decreased weight gain in children (not reported in this manuscript). For this paper, we focus on more proximal impacts on the food environment, and measure change in stocking, sales and purchase of promoted foods at the different levels of the food system in 14 intervention neighborhoods, as compared to 14 comparison neighborhoods. Sales of promoted products increased in wholesalers. Stocking of these products improved in corner stores, but not in carryouts, and we did not find any change in total sales. Children more exposed to the intervention increased their frequency of purchase of promoted products, although improvement was not seen for adult caregivers. A multilevel food environment intervention in a low-income urban setting improved aspects of the food system, leading to increased healthy food purchasing behavior in children.
