The Influence of Organizational Culture on School‐Based Obesity Prevention Interventions: A Systematic Review of the Literature

BACKGROUND

Although the influence of organizational culture has been examined on a variety of student outcomes, few studies consider the influence that culture may have on school‐based obesity prevention interventions. We present a systematic review of the literature to examine how elements of organizational culture may affect the adoption, implementation, and sustainability of school‐based obesity prevention interventions.

METHODS

Fourteen studies examining the impact of organizational‐level characteristics on school‐based obesity prevention interventions were identified through the online databases EBSCO (CINAHL, ERIC, Agricola), Web of Science, Medline (PubMed), and Scopus.

RESULTS

Five themes were identified as elements of organizational culture that influence the adoption, implementation, and sustainability of school‐based obesity prevention interventions: organizational response to limited resources, value placed on staff training and professional development, internal support, organizational values, and school climate.

CONCLUSIONS

Organizational culture can greatly influence the success of school‐based obesity interventions. The collection of data related to organizational‐level factors may be used to identify strategies for creating and sustaining a supportive environment for obesity prevention interventions in the school setting.

     

School‐Level Practices and Perceptions Associated With Salad Bars in Schools

BACKGROUND

Salad bars are placed in schools to promote fruit and vegetable consumption among students. This study assessed differences in school nutrition practices and perceptions in schools with and without salad bars.

METHODS

Cross‐sectional surveys were completed by school nutrition managers (N = 648) in Arizona schools participating in the National School Lunch Program during 2013–2014. Mixed general estimating equation binomial regressions assessed factors related to having a salad bar after mutually adjusting for clustering within districts, school level, free/reduced rate, and respondents' time in current position.

RESULTS

On average, 61% of schools reported having a salad bar. After adjustment, school nutrition managers were significantly more likely to report having a salad bar if they served lunch by grade level (vs mixed grades), had a full‐service kitchen, and their personal perception of salad bars was positive; schools were less likely to have a salad bar if menu and food service decisions were made at the school level.

CONCLUSIONS

Several school‐level nutrition practices and perceptions were associated with having a salad bar in schools. Enhancement of these factors may facilitate having salad bars in schools.

     

Effects of a School‐Based Pedometer Intervention in Adolescents: 1‐Year Follow‐Up of a Cluster‐Randomized Controlled Trial

BACKGROUND

Physical activity (PA) is one of the most important health behaviors that may be modified by each individual. To foster PA in adolescents, a school‐based intervention was evaluated.

METHODS

A cluster‐randomized controlled trial with preassessment in 2014 and follow‐up assessment in 2015 included 29 schools with 1020 students (47.6% girls, mean age = 13.69 years). Intervention students received pedometers and monitored their steps for 12 weeks. Classes with the most steps were awarded. Primary outcomes included moderate‐to‐vigorous PA, out‐of‐school sports activities, active transport assessed through questionnaires, as well as cardiorespiratory fitness measured using the 20‐m shuttle‐run test and anthropometric data (weight, height, body fat, and waist circumference) assessed by study staff.

RESULTS

Significant interaction terms between group and time were found for all 3 indicators of PA; intervention students showed a higher increase of PA than control students. The same pattern was shown for cardiorespiratory fitness, but the effect missed significance. A more favorable development for the intervention students was shown for body fat and waist‐to‐height ratio, while there was no effect on body mass index percentile.

CONCLUSIONS

An easy way to administer school‐based PA program may enhance students' leisure‐time PA even 1 year after the intervention has ended.

     

Impacts of a School‐Wide,Peer‐Led Approach to Sexuality Education: A Matched Comparison Group Design

BACKGROUND

Teen Prevention Education Program (PEP) is a school‐wide, peer‐led comprehensive sexuality education program currently implemented in more than 50 schools across 2 states. Many teen pregnancy prevention researchers and practitioners view peer‐led programs as a promising approach for reducing teen pregnancy and associated sexual risk behaviors. However, prior research on the effectiveness of these programs indicates mixed results.

METHODS

We randomly assigned schools to implement Teen PEP immediately (intervention group) or on a delayed schedule (comparison group) and used propensity score matching to improve the comparability of the study groups. We surveyed students at baseline and about 6 months after the program ended.

RESULTS

Teen PEP did not significantly impact rates of sexual activity or unprotected sex; however, the program led to improvements in exposure to information about sexual health topics and knowledge of preventing pregnancy and transmission of sexually transmitted infections.

CONCLUSIONS

Teen PEP succeeded in accomplishing some of its most proximal goals, increasing students' access to information and knowledge. However, we found little evidence that the program affects sexual risk‐taking within 6 months of its conclusion. Future research will examine the program's longer‐term impacts on sexual risk behaviors.

     

National Analysis of State Health Policies on Students' Right to Self‐Carry and Self‐Administer Asthma Inhalers at School

BACKGROUND

Asthma has no known cure, and though manageable, it disrupts the everyday lives of over 6 million US children. Because children spend more than half of their waking hours in school, students must be able to carry and administer their inhaler at school to manage their asthma.

METHODS

This policy paper is a comprehensive review of all 50 states and the District of Columbia's laws and policies for the self‐carry and administration of quick‐relief asthma inhalers among children in prekindergarten through 12th grade.

RESULTS

All states permit students to carry and administer their inhalers at school, although each state differs in their development and implementation of policies for asthma self‐management at school. This review examines how states regulate self‐carry policies by looking at policy development, regulated school systems, relevant stakeholders, required medical records, and school liability.

CONCLUSIONS

Each state's laws have nuances that create gray areas, increasing the potential of misinterpreted or incorrectly implemented policies for asthma self‐management at school. As a result, children may not have immediate access to their inhaler for symptom management or in an emergency. State policymakers should reform current laws to remove barriers for students to carry and use inhalers at school.

     

State Agency Support of Weight‐Related School Policy Implementation

BACKGROUND

In this study, we describe state agency strategies to support weight‐related policy implementation in schools, and examine the association among state support, obesity prevalence, and strength of state policies governing school nutrition and physical education.

METHODS

The 2012 School Health Policies and Practices Study describes prevalence of implementation support state agencies provided to schools/districts. Implementation support items were analyzed by weight‐related policy area (eg, advertising, wellness policy) and by type of support (eg, technical assistance). Results were summed to create a total weight‐related policy support score. Linear regression was used to examine associations between policy support and state youth obesity prevalence (2011‐2012 National Survey for Children's Health), overall and stratified by state policy strength (2012 Classification of Laws Associated with School Students).

RESULTS

States provided support most commonly for school meals and wellness policies (89% and 81%, respectively) and least often for after‐school PE (26%). Most states (80%) provided technical assistance. The total weight‐related policy support score had a significant positive association with state‐level youth overweight/obesity prevalence (p = .03).

CONCLUSION

State agencies appear to be responding to their youth obesity prevalence with technical support. Schools and state agencies should work in collaboration to provide a healthy school environment for all students.

     

School‐Level Socioeconomic Status Influences Adolescents' Health‐Related Lifestyle Behaviors and Intentions

BACKGROUND

School‐level socioeconomic status (SES) influences on adolescents' lifestyle behaviors is understudied. We examined how school‐level SES and sex influence adolescents' health‐related lifestyle behaviors and intentions.

METHODS

Grade 8 students aged 13‐14 years completed an online questionnaire regarding their sociodemographic characteristics, dietary behaviors, physical activity participation and recreational screen‐time, and intentions regarding these behaviors. School‐level SES, based on an Index of Community Socio‐Educational Advantage (ICSEA), was categorized as low or high. Generalized estimating equations estimated individual‐level summary statistics, adjusted for clustering.

RESULTS

Students (N = 2538; response rate = 79%) from 23 high schools (low ICSEA = 16) participated. Compared with low ICSEA students, high ICSEA students were more likely to report eating breakfast daily (OR 1.9 [95% CI 1.5, 2.4]), not drinking sugar‐sweetened beverages (SSBs) daily (2.9 [1.9, 4.3]), and were more likely to have intentions to eat breakfast (1.8 [1.3, 2.3]) and ≥ 5 vegetable serves (1.2 [1.0, 1.5]) daily. Boys were more likely than girls to meet recommendations for breakfast eating, vegetable intake, moderate‐to‐vigorous physical activity and screen‐time, but boys were less likely to meet recommendations regarding SSB intake.

CONCLUSIONS

Students from low ICSEA schools would benefit from additional support to improve dietary‐related behaviors and intentions. More research is required to identify what targeted approaches will address sex differences in adolescents' lifestyle behaviors.

     

School Factors Associated With the Implementation of Integrated Pest Management‐Related Policies and Practices

BACKGROUND

Schools are particularly vulnerable to pests, but integrated pest management (IPM) can address pest problems. This study describes IPM policies and practices and the extent to which they are associated with school characteristics.

METHODS

We analyzed data from the 2014 School Health Policies and Practices Study, a nationally representative survey of schools in the United States (N = 568, response rate = 69%). Pairwise comparisons assessed differences in pest prevention strategies by school characteristics.

RESULTS

Nationwide, 55.3% of schools conducted campus‐wide inspections for pests at least monthly; 35.6% of schools notified staff, students, and families prior to each application of pesticides; and 56.1% of schools required custodial or maintenance staff to receive training on pest management practices that limit the use of pesticides. During the 12 months before the study, 46.5% of schools almost always or always used spot treatments and baiting rather than widespread applications of pesticides, and 36.8% of schools almost always or always marked indoor and outdoor areas that had been treated with pesticides. No clear pattern emerged for school characteristics associated with IPM policies and practices.

CONCLUSIONS

The variation in implementation of IPM‐related policies and practices suggest opportunities for targeted education among school staff about IPM principles.

     

School Wellness Committees Are Associated With Lower Body Mass Index Z‐Scores and Improved Dietary Intakes in US Children: The Healthy Communities Study

BACKGROUND

Our objective was to examine the association between school wellness committees and implementation of nutrition wellness policies and children's weight status and obesity‐related dietary outcomes.

METHODS

A cross‐sectional study was conducted of 4790 children aged 4‐15 years recruited from 130 communities in the Healthy Communities Study. Multilevel statistical models assessed associations between school wellness policies and anthropometric (body mass index z‐score [BMIz]) and nutrition measures, adjusting for child and community‐level covariates.

RESULTS

Children had lower BMI z‐scores (?0.11, 95% confidence interval [CI]: ?0.19, ?0.03) and ate breakfast more frequently (0.14 days/week, 95% CI: 0.02‐0.25) if attending a school with a wellness committee that met once or more in the past year compared to attending a school with a wellness committee that did not meet/did not exist. Children had lower added sugar (p < .0001), lower energy‐dense foods (p = .0004), lower sugar intake from sugar‐sweetened beverages (p = .0002), and lower dairy consumption (p = .001) if attending a school with similar or stronger implementation of the nutrition components of the school wellness policies compared to other schools in the district.

CONCLUSIONS

A more active wellness committee was associated with lower BMI z‐scores in US schoolchildren. Active school engagement in wellness policy implementation appears to play a positive role in efforts to reduce childhood obesity.

     

Academic‐Related Factors and Emotional Eating in Adolescents

BACKGROUND

Existing literature indicates a relationship between stress and emotional eating in adults, yet limited research has examined the impact of school‐related stress on emotional eating in adolescents. This study investigated the influence of academic factors on emotional eating among minority adolescents.

METHODS

A survey was implemented among a sample of minority adolescents (N = 666) to investigate the relationship between emotional eating and 3 academic factors: academic self‐esteem, grade point average (GPA), and academic worries. Forced‐entry multiple linear regressions were used to test for relationships.

RESULTS

Findings indicate that GPA, academic self‐esteem, and academic worries were related to emotional eating scores in adolescents. There were no significant differences in academic factors between emotional eaters and nonemotional eaters.

CONCLUSIONS

Additional research is needed to further elucidate the complex interaction between emotional eating behavior and academics.

     

Assessing School Wellness Policies and Identifying Priorities for Action: Results of a Bi‐State Evaluation

BACKGROUND

Obesity is a complex health problem affecting more than one‐third of school‐aged youth. The increasing obesity rates in Kansas and Missouri has been particularly concerning, with efforts being made to improve student health through the implementation of school wellness policies (SWPs). The primary purpose of this study was to conduct a rigorous assessment of SWPs in the bi‐state region.

METHODS

SWPs were collected from 46 school districts. The Wellness School Assessment Tool (WellSAT) was used to assess comprehensiveness and strength. Additionally, focus group discussions and an online survey were conducted with school personnel to identify barriers and supports needed.

RESULTS

Assessment of the SWPs indicated that most school districts failed to provide strong and specific language. Due to these deficiencies, districts reported lack of enforcement of policies. Several barriers to implementing the policies were reported by school personnel; supports needed for effective implementation were identified.

CONCLUSIONS

To promote a healthful school environment, significant improvements are warranted in the strength and comprehensiveness of the SWPs. The focus group discussions provided insight as to where we need to bridge the gap between the current state of policies and the desired beneficial practices to support a healthy school environment.

     

School Connectedness and Chinese Adolescents' Sleep Problems: A Cross‐Lagged Panel Analysis

BACKGROUND

Although previous research indicates an association between school connectedness and adolescents' sleep quality, its causal direction has not been determined. This study used a 2‐wave cross‐lagged panel analysis to explore the likely causal direction between these 2 constructs.

METHODS

Participants were 888 Chinese adolescents (43.80% boys; M_age = 15.55) who provided self‐report data on school connectedness and sleep quality as well as demographic variables at the beginning and the end of a school year.

RESULTS

After controlling for sex and age, we found that sleep problems at the beginning of the school year were a significant and negative predictor of school connectedness at the end of the school year (b₂ = ?.26, SE = .13, β₂ = ?.10, p < .05), but school connectedness at the beginning of the school year did not predict sleep problems at the end of the school year (b₁ = .05, SE = .03, β₁ = .09, p > .05). Separate analyses by sex showed that the above pattern of results was mainly driven by the boys.

CONCLUSIONS

Our findings demonstrated that sleep problems could be a risk factor for adolescent boys' school connectedness.

     

Formative Research to Create a Farm‐to‐School Program for High School Students in a Lower Income,Diverse, Urban Community

BACKGROUND

Using Social Cognitive Theory as a framework, we examined opportunities for promoting local produce consumption among high school students in a lower‐income, ethnically diverse, urban community.

METHODS

Six focus groups (N = 53) were conducted with students. Using Atlas.ti qualitative software, data were coded and reviewed to identify code categories which could be taken to represent themes.

RESULTS

Students (56.8% girls, 86.5% nonwhite) described local produce as being grown “nearby” or “in Connecticut.” Overwhelmingly, students perceived local produce to be of higher quality (eg, “tastes better,” “fresher”) than nonlocal produce. Students reported that the foods served at school are “unnatural” and “made in a factory.” Salient perceived outcomes associated with consuming local produce included “benefits the environment,” “builds community and trust,” and “keeps taxes down.” Students recommended hanging large colorful posters highlighting the positive outcomes associated with consuming local produce in school locations with captive audiences such as lunch lines and classrooms. Labels identifying the food origins of cafeteria foods provided as well as taste tests of local produce might support students' self‐efficacy for consuming local fruits and vegetables.

CONCLUSIONS

These findings provide theory‐based strategies for how to promote local produce consumption among a diverse group of urban high schools students.

     

Enhancing Educator Engagement in School Mental Health Care Through Digital Simulation Professional Development

BACKGROUND

Despite the critical role of educators as gatekeepers for school mental health services, they receive limited training to support student mental health. We report findings from a trial of an online mental health role‐play simulation for elementary school teachers on changes in attitudes and self‐reported helping behaviors for students experiencing psychological distress.

METHODS

We randomly assigned 18,896 elementary school teachers to wait‐list control or intervention conditions in which they received the 45‐ to 90‐minute online role‐play simulation. We administered a version of the validated Gatekeeper Behavior Scale at baseline and postintervention, which measures attitudinal dimensions shown to predict teacher helping behavior change. Self‐reported helping behaviors were collected at baseline and 3‐month follow‐up. Outcomes were compared between the intervention follow‐up and control group baseline measures.

RESULTS

The intervention group posttraining scores were significantly higher (p < .001) than the control group for all the preparedness, likelihood, and self‐efficacy Gatekeeper Behavior subscales. All 5 helping behaviors were significantly higher among the intervention group at follow‐up compared to the control group at baseline.

CONCLUSIONS

We found that a brief online role‐play simulation was an effective strategy for improving teacher attitudes and behaviors needed to perform a positive mental health gatekeeper role in schools.

     

Active Commuting to School,Physical Activity,and Behavior Problems Among Third‐Grade Children

BACKGROUND

We examined factors associated with active commuting to school and the relationships of active commuting and physical activity to child‐ and teacher‐reported internalizing and externalizing behavior problems in a sample of third graders.

METHODS

The study sample consisted of 13,166 third graders enrolled in the Early Childhood Longitudinal Study Kindergarten Class of 1998‐1999. “Active” commuters were children who walked to school and “passive” commuters were those who took the bus or were driven. Linear analyses evaluated differences in behavior problems by school commute, physical activity, and sports team participation after adjusting for sociodemographic, regional, and neighborhood factors.

RESULTS

Overall, 11% of children actively commuted. Type of commute differed by sociodemographics, region, urbanicity, school type, and neighborhood safety. Active commuters had less general physical activity participation and sports team participation. Commuting type and general physical activity were not associated with behavior problems, but sports team participation was associated with fewer child‐reported internalizing and externalizing behaviors as well as fewer teacher‐reported internalizing behaviors.

CONCLUSIONS

Our findings demonstrate the ongoing need for creating and maintaining physical activity programs (such as sports teams) among school‐aged children to optimize children's overall health and well‐being.

     

Addressing Gaps in Cardiopulmonary Resuscitation Education: Training Middle School Students in Hands‐Only Cardiopulmonary Resuscitation

BACKGROUND

Training middle school students to perform hands‐only cardiopulmonary resuscitation (HOCPR) is a potential method to increase overall rates of bystander cardiopulmonary resuscitation (CPR). We aimed to examine the feasibility of teaching this population CPR using teacher‐implemented education sessions guided by American Heart Association (AHA) training kits and resources.

METHODS

We conducted a national HOCPR training campaign in middle schools during the 2014‐2015 school year. Participating schools utilized AHA CPR training kits to train seventh and eighth grade students. We assessed pretest/posttest knowledge and comfort in performing HOCPR.

RESULTS

We recruited 1131 schools and trained approximately 334,610 students in HOCPR. The average pretest score on knowledge questions was 50% and the average posttest score was 84%. Most students (76%) felt comfortable performing HOCPR after the education session. Overall, 98% of teachers said they would continue to implement CPR training in the future.

CONCLUSIONS

Large‐scale, teacher‐implemented CPR education sessions in the middle school setting are a successful approach to increase middle school student's knowledge and comfort in performing HOCPR and to increase overall bystander CPR rates.

     

Barriers to the Administration of Epinephrine in Schools

BACKGROUND

Anaphylaxis is a serious and growing concern in the school setting as the prevalence of food allergies and food‐induced severe allergic reactions continues to increase.

METHODS

A cross‐sectional, web‐based survey was conducted regarding anaphylactic events that occurred during the 2014‐2015 school year. Eligible schools were enrolled in the EPIPEN4SCHOOLS^® program (Mylan Specialty L.P., Canonsburg, PA), which provides free epinephrine auto‐injectors to qualifying US schools. Participating schools completed a 29‐item survey on anaphylactic event occurrence and treatment, epinephrine stock, school policies regarding anaphylaxis, school staff training, and school nursing coverage.

RESULTS

Responses were provided by 12,275 schools. Epinephrine was administered on school property for 63.7% of reported anaphylactic events (1272/1998). In 38.5% (235/610) of events for which epinephrine was not used, antihistamines were cited as the reason. Only 59.4% of schools cited epinephrine as their standard first‐line therapy for anaphylaxis. School nurses were most likely to be trained in anaphylaxis recognition and permitted to administer epinephrine; however, just 53.6% of schools had a full‐time nurse on staff.

CONCLUSIONS

Process‐related barriers to the appropriate use of epinephrine go beyond access to medication. Widespread staff training and review of school policies are needed to ensure that anaphylaxis is appropriately managed in schools.

     

The School Contextual Effect of Sexual Debut on Sexual Risk‐Taking: A Joint Parameter Approach

BACKGROUND

Previous research has identified individual and school‐level characteristics that are associated with sexual risk‐taking, but the impact of school‐level mechanisms on sexual risk‐taking is not well understood. We examine the aggregated effects that early sex at the school level have on risky sexual behaviors.

METHODS

We use 3 waves of data from the National Longitudinal Study of Adolescent Health. An individual's first sexual intercourse before age 15 was recorded along with various risky sexual behaviors at debut. Two variables at respondent's later stage of life were also included: having sex in exchange for drugs or money, and contraction of sexually transmitted disease (STD). Longitudinal analysis was conducted using a joint parameter model that tested unobserved school effects on individual behaviors simultaneously.

RESULTS

An increase in early sexual initiation at the school level was associated with higher probability of sexual debut, along with increased involvement in sexual risk‐taking controlling for student family background.

CONCLUSIONS

School behavioral mechanisms are directly related to sexual health behaviors among youth. Our findings have implications for school‐based interventions, education programs, and the role of parents.

     

Later Start,Longer Sleep: Implications of Middle School Start Times

BACKGROUND

Although adolescents generally get less than the recommended 9 hours of sleep per night, research and effort to delay school start times have generally focused on high schools. This study assesses the relation between school start times and sleep in middle school students while accounting for potentially confounding demographic variables.

METHODS

Seventh and eighth grade students attending 8 late starting schools (～8:00 am , n = 630) and 3 early starting schools (～7:23 am , n = 343) from a diverse suburban school district completed online surveys about their sleep behaviors. Doubly robust inverse probability of treatment weighted regression estimates of the effects of later school start time on student bedtimes, sleep duration, and daytime sleepiness were generated.

RESULTS

Attending a school starting 37 minutes later was associated with an average of 17 additional minutes of sleep per weeknight, despite an average bedtime 15 minutes later. Students attending late starting schools were less sleepy than their counterparts in early starting schools, and more likely to be wide awake.

CONCLUSIONS

Later school start times were significantly associated with improved sleep outcomes for early adolescents, providing support for the movement to delay school start times for middle schools.
