School Disrepair and Substance Use Among Regular and Alternative High School Students

BACKGROUND: The physical environment influences adolescent health behavior and personal development. This article examines the relationship between level of school disrepair and substance use among students attending regular high school (RHS) and alternative high school (AHS). METHODS: Data were collected from students (N = 7058) participating in 2 randomized controlled trials of a school-based substance abuse prevention program implemented across the United States. Students provided substance use and demographic information on a self-reported survey. Data for the physical disrepair of schools were collected from individual rater observations of each school environment. We hypothesized that school disrepair would be positively associated with substance use controlling for individual characteristics and a socioeconomic status proxy. Multilevel mixed modeling was used to test the hypothesized association and accounted for students nested within schools. RESULTS: Findings indicated that students attending AHS with greater school disrepair were more likely to report the use of marijuana and other illicit drugs (ie, cocaine, heroin). Students attending RHS with greater school disrepair were less likely to report smoking cigarettes. CONCLUSIONS: Differences in findings between RHS and AHS students are discussed, and implications for substance use prevention programming are offered. Students attending AHS with greater school disrepair may require more substance abuse prevention programming, particularly to prevent illicit substance use.     

Correlates of Condom Use Among Male High School Students in Nairobi, Kenya

BACKGROUND: Correct and consistent condom use is an effective strategy to reduce the risk of sexually transmitted infections (STIs). This study examines sociodemographic, behavioral, and psychosocial characteristics of 3 groups of adolescent males: consistent, sporadic, and non-condom users.
METHODS: The sample consisted of 931 sexually experienced male high school students in Nairobi, Kenya. Cross tabulations and general linear models were used to test the relation between each explanatory variable and condom user group.
RESULTS: Fifty-three percent of respondents reported having used condoms. Compared with nonusers and sporadic users, consistent users engaged in sexual intercourse for the first time at an older age and reported higher condom use self-efficacy, more positive peer attitudes toward safe sex, and stronger attitudes toward condom use. Compared with sporadic and consistent users, nonusers reported fewer sexual partners, less substance use, and more frequent intercourse with non-romantic partners. Sporadic users, compared with the other 2 groups, had more sexual partners and stronger attitudes that support that males and females have separate roles. The 3 groups did not differ in HIV/AIDS knowledge. On average, respondents responded correctly to two thirds of the questions. All groups perceived their risk of contracting an STI as low, and this perception did not differ by condom use. Differences in participants' age by group were minimal.
CONCLUSIONS: The study supports the need for interventions that target specific condom use groups.     

Social Environments and Physical Aggression Among 21,107 Students in the United States and Canada

Background: Physical aggression is an important issue in North American populations. The importance of students’ social environments in the occurrence of physical aggression requires focused study. In this study, reports of physical aggression were examined in relation to social environment factors among national samples of students from Canada and the United States. Methods: Students in grades 6‐10 from the United States (n = 14,049) and Canada (n = 7058) who had participated in the Health Behaviour in School‐aged Children Survey (HBSC) were studied. Rates of students’ physical aggression were compared between the 2 countries. School, family, socioeconomic, and peer‐related factors were considered as potential risk factors. A simple social environment risk score was developed using the US data and was subsequently tested in the Canadian sample. Results: Risks for physical aggression were consistently higher among United States versus Canadian students, but the magnitude of these differences was modest. The relative odds of physical aggression increased with reported environmental risk. To illustrate, US boys in grades 6‐8 reporting the highest social environment risk score (5+) experienced a relative odds of physical aggression 4.02 (95% CI 2.7‐5.9) times higher than those reporting the lowest score (adjusted OR for risk scores 0 through 5+ was 1.00, 1.19, 2.10, 2.01, 3.71, and 4.02, respectively, p_trend < .001). Conclusions: Unexpectedly, rates of physical aggression and associations between social environments and students’ aggression were remarkably similar in Canada and the United States. Family, peer, and school social environments serve as risk or protective factors, with significant cumulative impact on physical aggression in both countries. Given the observed high rates and the many negative effects of aggression on long‐term health, school policies aimed at the reduction of such behavior remain a clear priority.     

A Multilevel Examination of School and Student Characteristics Associated With Physical Education Class Enrollment Among High School Students

BACKGROUND: Schools can be an efficient venue for promoting physical activity (PA) among adolescents. Physical education (PE) requires investigation because it is a variable associated with adolescent PA levels and its existence in schools represents a significant opportunity for strategies to combat declining PA levels among this population. This article examines the between-school variability in student rates of PE enrollment among a large sample of high schools in Ontario, Canada, and identifies the school- and student-level characteristics associated with PE enrollment. METHODS: This cross-sectional study utilized self-reported school- and student-level data from administrators and students at 73 high schools. Students' enrollment in PE, demographic, behavioral, and psychosocial variables was linked to school environment data comprising of school demographics and administrator assessed quality of policies, facilities, and programs related to PA. Analysis involved multilevel modeling. RESULTS: The mean rate of PE enrollment among the 73 high schools was 62.4%, with rates by school ranging from 28.9% to 81.1%. When student demographics, behavioral, and psychosocial factors were controlled for, there was still a school effect for student PE enrollment. The school effect was explained by the provision of daily PE and school median household income. CONCLUSIONS: This is the first study to examine the extent to which PE enrollment varies between schools and to identify school factors associated with school variability in rates of PE enrollment. Although most variation in PE enrollment lies between students within schools, there is sufficient between-school variation to be of interest to practitioners and policy makers.     

Evaluation of a School-Based Train-the-Trainer Intervention Program to Teach First Aid and Risk Reduction Among High School Students

BACKGROUND: Farming is a hazardous occupation posing health risks from agricultural exposures for the farm owner and family members. First Aid for Rural Medical Emergencies (F.A.R.M.E.) was developed to support a train-the-trainer (TTT) program to prepare high school students to teach first aid skills and risk reduction through peer interaction. This study was designed to evaluate the educational effectiveness for first aid skill development and awareness of safety issues and injury prevention impacting agricultural communities. METHODS: Forty-three agricultural science students from a rural high school participated in the study. A quasi-experimental design was used to evaluate knowledge acquisition and anticipatory action among groups: those participating in training and a comparison group with no training. The intervention group included 27 participants trained as first aid peer instructors using the F.A.R.M.E. manual, return demonstration, case scenario facilitation training, and teaching evaluation sessions. The effectiveness of the program was evaluated using triangulated data. Independent t test analyses were conducted on post-test scores to evaluate the knowledge acquisition and anticipatory action scores between groups. Focus group sessions assessed attitudes, experiences, and values held following the intervention of teaching peers. RESULTS: Results indicate that the intervention group scored significantly higher on anticipatory action (t = 2.23, p = .03) but not knowledge acquisition (t = 1.37, p = .18). Focus group data suggest that the TTT format bolstered confidence in teaching, confirmed that teens enjoy learning from teens, and fostered pride in team work. CONCLUSIONS: The F.A.R.M.E. TTT resulted in a theory and evidence-based intervention that can be implemented in a school setting to promote knowledge and skill acquisition of first aid and injury prevention among rural high school students.     

Prevalence and Correlates of Sunscreen Use Among US High School Students

Sun exposure during childhood and adolescence increases the risk of skin cancer later in life. To determine the prevalence and correlates of sunscreen use among US high school students, researchers assessed data on sunscreen use, demographic characteristics, and health behaviors obtained from the 1999 Youth Risk Behavior Survey (YRBS). This survey used a three-stage cluster sample design to produce a nationally representative sample of students in grades 9-12 (N = 15,349). Overall, 13.3% (95% confidence interval, +/- 1.3) of students used sunscreen always or most of the time (i.e., frequent use). Frequent sunscreen use was lower among males (8.6%, +/- 1.2) than females (18.1%, +/- 1.9) and among Blacks (4.8%, +/- 1.7) and Hispanics (10.8%, +/- 2.8) than Whites (16.5%, +/- 1.9). Frequent sunscreen use decreased with age. Infrequent use of sunscreen was associated with other risky health behaviors, such as driving after drinking or riding in a car with a drinking driver, smoking cigarettes, being sexually active, and being physically inactive. Results indicate a need for health education interventions addressing sunscreen use that target high school students.     

A Comparison of Weight-Related Behaviors Among High School Students Who Are Homeless and Non-Homeless

BACKGROUND: Previous research has shown that youth who are homeless engage in high-risk behaviors. However, there has been little information published on nutritional and physical activity behaviors in this population, and studies comparing homeless youth in school with their non-homeless peers are scarce. This study compares weight-related risk behaviors of public high school students in Massachusetts based on homeless status.
METHODS: We obtained data from 3264 9th through 12th grade students who participated in the 2005 Massachusetts Youth Risk Behavior Survey. Multivariable logistic regression, controlling for gender, grade, race/ethnicity, and sexual orientation, was performed to assess the relationship between homeless status as defined by the McKinney-Vento Homeless Assistance Act and weight-related indicators. Analyses were weighted and adjusted for the multistage complex sampling design.
RESULTS: Of this sample, 4.2% reported being homeless (n = 152). Higher prevalence of homelessness was found among males, racial/ethnic minorities, sexual minorities, and students who were not in a traditional grade level. The distribution of body mass index was similar among students who were homeless and non-homeless (underweight 4.0 and 3.0%, and overweight 27.1 and 27.1%, respectively). Homeless students were more likely than non-homeless students to report disordered weight-control behaviors including fasting (aOR 2.5, 95% CI 1.4–4.5) and diet pill use (aOR 3.3, 95% CI 1.6–6.9).
CONCLUSIONS: More than 4% of public high school students in Massachusetts meet the federal definition of homelessness. These students are at high risk for disordered weight-control behaviors. Policy decisions at the school, state, and federal levels should make a concerted effort to target these students with social services and nutritional interventions.     

School Policies and Practices That Improve Indoor Air Quality*

BACKGROUND: To determine whether schools with a formal indoor air quality management program were more likely than schools without a formal program to have policies and practices that promote superior indoor air quality. METHODS: This study analyzed school-level data from the 2006 School Health Policies and Programs Study, a national study of school health programs and policies at the state, district, and school levels. Using chi-square analyses, the rates of policies and practices that promote indoor air quality were compared between schools with and schools without a formal indoor air quality program. RESULTS: The findings of this study show that 51.4% of schools had a formal indoor air quality management program, and that those schools were significantly more likely than were schools without a program to have policies and use strategies to promote superior indoor air quality. CONCLUSIONS: These findings suggest that schools with a formal indoor air quality program are more likely support policies and engage in practices that promote superior indoor air quality.
