A qualitative study exploring how school and community environments shape the food choices of adolescents with overweight/obesity.

This study explored perceived barriers and facilitators to healthful eating in schools and communities among overweight teens who completed an E-health intervention. Twenty-two teens were recruited to a photovoice study and asked to take pictures of things that made it easier or harder to make healthful food choices at school and in their community. Digital photographs were reviewed using semi-structured interviews. Transcribed audio-recordings were analyzed using constant comparative analysis. Similar themes emerged from the school and community environments with food/beverage availability emerging most frequently, followed by peer influence, accessibility/convenience, price, classroom practices, marketing and online influences. Teens described an obesity-promoting environment and perceived very limited healthful options. Policy-driven environmental changes as well as strategies that help teens navigate food choices in their schools and communities are needed to support healthful eating.

Adolescent smoking: effect of school and community characteristics.

BACKGROUND: A substantial challenge in addressing adolescent tobacco use is that smoking behaviors occur in complex environments that involve the school setting and larger community context. PURPOSE: This study provides an integrated description of factors from the school and community environment that affect youth smoking and explains variation in individual smoking behaviors both within and across schools/communities. METHODS: Data were collected from 82 randomly sampled secondary schools in five Canadian provinces (British Columbia, Manitoba, Ontario, Quebec, Newfoundland, and Labrador) during the 2003-2004 school year. Cross-sectional data were obtained from students; school administrators (school-based tobacco control policies and programs); and from observations in the community. In 2009, hierarchic logistic regression was used to model the role of individual, school, and community variables in predicting student smoking outcomes. RESULTS: Students who attended a school with a focus on tobacco prevention (OR=0.87, 95% CI=0.81, 0.94) and stronger policies prohibiting tobacco use (OR=0.92, 95% CI=0.88, 0.97) were less likely to smoke than students who attended a school without these characteristics. A student was more likely to smoke if a greater number of students smoked on the school periphery (OR=1.25, 95% CI=1.07, 1.47). Within the community, price per cigarette (OR=0.91, 95% CI=0.84, 0.99) and immigrants (OR=0.99, 95% CI=0.98, 0.99) were inversely related to students' smoking status. CONCLUSIONS: The results suggest that school and community characteristics account for variation in smoking levels across schools. Based on the current findings, the ideal school setting that supports low student smoking levels is located in a neighborhood where the cost of cigarettes is high, provides tobacco prevention education, and has a policy prohibiting smoking.

The influence of school policies on smoking prevalence among students in grades 5-9, Canada, 2004-2005.

INTRODUCTION: School characteristics may account for some of the variation in smoking prevalence among schools. The purpose of this study was to investigate the relationships between characteristics of school tobacco policies and school smoking prevalence. We also examined the relationship between these characteristics and individual smoking status. METHODS: Tobacco policy data were collected from schools in 10 Canadian provinces during the 2004-2005 school year. Written tobacco policies were collected from each school to examine policy intent, and school administrators were surveyed to assess policy enforcement. Students in grades 5 through 9 completed the Youth Smoking Survey to assess smoking behaviors and attitudes. We used negative binomial regression and multilevel logistic regression to predict the influence of school policies on smoking behavior at the school and student levels. RESULTS: School policies that explicitly stated purpose and goals predicted lower prevalence of smoking at the school and individual levels. Policies that prohibited smoking on school grounds at all times predicted lower smoking prevalence at the school level but not at the individual level. CONCLUSION: For maximum effectiveness, school smoking policies should clearly state a purpose and goals and should emphasize smoking prohibition. These policies can help reduce smoking prevalence among youths and are part of a comprehensive school approach to tobacco control.

Do students' perceptions of school smoking policies influence where students smoke?: Canada's Youth Smoking Survey.

OBJECTIVE: The objective of this study was to explore students' perceptions of school policy characteristics that influence the location of smoking while at school. METHODS: Data were collected from a nationally representative sample of Canadian youth in grades 7-12 as part of the 2006-2007 Youth Smoking Survey. We used multilevel logistic regression to examine how students' perceptions of school policies predicted smoking behavior on and off school grounds in 11,881 students who had ever smoked. Separate analyses were conducted for grades 7-9 and 10-12. RESULTS: In both grades 7-9 and 10-12, perceiving clear rules about smoking decreased the likelihood that a student would smoke on school grounds, while perceiving that a high percentage of peers smoke, that there are school rules about smoking, that students obey the rules, and that students can be fined for smoking increased the likelihood that a student would smoke off school grounds. CONCLUSIONS: Clearly perceived rules about smoking encourage students not to smoke on school grounds; however, perceptions of rules, along with strong enforcement, may displace behavior off of school grounds. Non-smoking policies should be part of a comprehensive approach, that supports cessation.

School smoking policy characteristics and individual perceptions of the school tobacco context: are they linked to students' smoking status?

The purpose of this study was to explore individual- and school-level policy characteristics on student smoking behavior using an ecological perspective. Participants were 24,213 (51% female) Grade 10-11 students from 81 schools in five Canadian provinces. Data were collected using student self-report surveys, written policies collected from schools, interviews with school administrators, and school property observations to assess multiple dimensions of the school tobacco policy. The multi-level modeling results revealed that the school a student attended was associated with his/her smoking behavior. Individual-level variables that were associated with student smoking included lower school connectedness, a greater number of family and friends who smoked, higher perceptions of student smoking prevalence, lower perceptions of student smoking frequency, and stronger perceptions of the school tobacco context. School-level variables associated with student smoking included weaker policy intention indicating prohibition and assistance to overcome tobacco addiction, weaker policy implementation involving strategies for enforcement, and a higher number of students smoking on school property. These findings suggest that the school environment is important to tobacco control strategies, and that various policy dimensions have unique relationships to student smoking. School tobacco policies should be part of a comprehensive approach to adolescent tobacco use.

Tobacco Point-of-Purchase marketing in school neighbourhoods and school smoking prevalence: a descriptive study.

BACKGROUND: Point of Purchase (PoP) promotional and advertising activities are a sophisticated tobacco marketing strategy. This study describes tobacco PoP activities in school neighbourhoods and compares PoP activities in retail stores between schools with high and low smoking prevalence. METHODS: A cross-sectional study was conducted in 81 randomly selected schools across five provinces. Students in grades 10-11 completed a questionnaire on smoking. Observations were made in all retail stores located within a one-kilometre radius around the school. ANOVA tests were used to detect differences on PoP variables between high (> 20.6%) and low (< or = 20.6%) smoking prevalence schools, defined as percentage of students reporting at least a few puffs on > 2 days in the last 30 days. RESULTS: Approximately half of retail stores in each school neighbourhood exhibited tobacco PoP activities. Average school smoking prevalence was 20.99%. There were significant main effects on PoP variables between schools with high and low smoking prevalence, Wilk's lambda = 0.81, F (6,74) = 2.89, p < 0.01, eta2 = 0.19. Stores near schools with high smoking prevalence had significantly lower prices per cigarette (F (1,79) = 15.34, p < 0.01, eta2 = 0.16), more in-store promotions (F (1,79) = 6.73, p < 0.01, eta2 = 0.08), and fewer government-sponsored health warnings (F (1,79) = 6.26, p < 0.01, eta2 = 0.07) compared to schools with low smoking prevalence. CONCLUSION: Higher levels of PoP activities in stores located in the school neighbourhood are related to school smoking prevalence. Schools with low smoking prevalence had more stores that posted government health warning signs and higher cigarette prices. Legislation regulating PoP activities and health warnings in school neighbourhoods should be considered.

Smoking decisions from a teen perspective: a narrative study.

OBJECTIVE: To explore the transitional phase between experimental and regular smoking from the perspective of teens. METHOD: Narrative analysis of semistructured, individual interviews. RESULTS: The need to belong and immediate social gain are major themes influencing teen smoking decisions. CONCLUSIONS: Our findings have significance for public health workers planning and implementing tobacco-use prevention programs aimed at teens whose smoking behaviors are not yet determined by nicotine addiction. How such programs have been traditionally framed and the ways in which peer influence and risk behaviors have been addressed may be largely irrelevant to the rationale of the adolescents themselves.

Crossing the line: adolescents' experiences of controlling their tobacco use.

Although adolescents are often curious about cigarettes and anxious to "try" smoking, they are unsure about what engaging in the act of smoking will mean. Most adolescents who experiment with smoking do not set out to become addicted to tobacco. Using a grounded theory approach, the authors examined the process youth undergo to regain control over their smoking. Accounts of early smoking experiences suggest that youth undergo a process to control tobacco use that includes (a) determining if smoking is a problem, (b) "crossing the line" of acceptable tobacco use, and (c) implementing strategies to regain control of smoking. The findings of this study lay the basis for the development of harm reduction approaches that facilitate youth's propensity to control their tobacco use.

Smoking and adolescence: narratives of identity.

The purpose of this study was to understand the identities that youth hold in relation to smoking, as revealed in narrative accounts of their smoking experiences. The analysis was a narrative inquiry, a qualitative approach based on the propensity of people to narrate or tell stories about the experiences in their daily lives. A purposeful sample of 35 youths ages 14-18 years with a variety of smoking histories (all had tried smoking) participated in in-depth interviews. A detailed analysis of the transcripts revealed the key identities communicated by the youths including the confident nonsmoker, the vulnerable nonsmoker, the ardent nonsmoker, the accepting nonsmoker, the in-control smoker, the confirmed smoker, and the contrite smoker. Tobacco control interventions for youth must be designed to respond to and incorporate multiple smoking identities.

Application of a better practices framework to review youth tobacco use cessation.

OBJECTIVE: To describe the Better Practices model and its application to review youth tobacco cessation practices. METHODS: Growing emphasis on evidence-based practice in health has drawn attention to methods for the identification of "best practices." Canadian organizations and government collaborated to develop a framework for "better" practices. RESULTS: An international group of experts used the model to develop recommendations for the practice of youth cessation and further research needed to advance the field. CONCLUSIONS: Tension persits between the need for rigor in research and the need for practical intervention guidance. The Better Practices model provided a framework for action recognizing these needs, and its use resulted in a number of valuable products.

Tobacco dependence: adolescents' perspectives on the need to smoke.

To address the need for a better understanding of the perspective of Canadian youths on tobacco dependence, a qualitative study using ethnographic techniques was conducted to describe the patterns of language that they use to describe tobacco dependence and the meaning that it has for them. The study was comprised of three inter-related phases: (1) A secondary analysis of 47 individual unstructured interviews with adolescents was completed to identify the words and phrases they use to explain tobacco dependence; (2) contrast and structural questions focusing on tobacco dependence were developed and used in open-ended interviews with 13 adolescents. Data analysis of the transcribed interviews resulted in a set of 60 key phrases that represented the primary ways youths describe the need to smoke; and (3) interviews were conducted with 14 adolescents that involved an open card sort using the set of 60 key phrases. All card sorts and transcribed interview data were analyzed to identify domains representing types of tobacco dependence and sub-types within each domain. From their descriptions about the need to smoke, five aspects of tobacco dependence were identified: social, pleasurable, empowering, emotional, and full-fledged. This study provides a step in elucidating the construct of tobacco dependence among the young. Further research is required to extend this understanding and to develop appropriate measures.
