Schools represent an ideal environment for increasing sports participation, but it is unclear how access and choice influence participation and whether characteristics of the school sports program differentially influence boys' and girls' participation. The purpose of this study was to evaluate the characteristics of high school athletic programs and determine the extent to which these characteristics influenced boys' and girls' sports team participation. Methods: Longitudinal telephone surveys were conducted with 1244 New Hampshire and Vermont students. Students self-reported their sports team participation at baseline (elementary school) and follow-up (high school). High school personnel were surveyed to assess sports oppor- tunities, which were defined for this analysis as the number of sports offered per 100 students (i.e., choice) and the percent of sports offered that did not restrict the number of players (i.e., access). Results: Approximately 70% of children participated on at least one sports team, including 73% of boys and 66% of girls. We detected sta- tistically significant interactions between sex and two school opportunity variables: 1) the number of sports offered per 100 students (i.e., choice) and 2) the percent of sports offered that did not restrict the number of players (i.e., access). After controlling for children's baseline sports participation and other covariates, boys were more likely to play on at least one sports team per year if their school did not restrict participation in the most popular sports (relative risk, RR = 1.12, p 〈 0.01); in contrast, girls were more likely to play on at least one sports team per year if their school offered a wider variety of sports (RR = 1.47, p 〈 0.001). Conclusion: Sports participation has previously been shown to confer a number of health benefits; as such, school sports programs may be an important, effective, and underused target for public health efforts, including obesity prevention programs. Efforts to increase physical activity among youth should consider both access and choice in school athletic programs. Schools may need to use different strategies to increase sports participation in boys and girls.展开更多

The objective was to develop the participatory program for dengue prevention and control in five primary schools. Participatory action research (PAR) was applied in five steps: 1) preparation, 2) assessment, 3) education program development, 4) implementation and 5) evaluation. Data collection used quantitative and qualitative methods in five primary schools in Southern, Thailand. Descriptive statistics and Chi-square (χ2) test were used to compare between pre- and post-intervention. Larval Indices were obtained from ratio analysis. The results showed the participatory program consisted of nine important activities for all stakeholders involving dengue problem. Health teacher’s activities and student’s activities were eight activities consisted of knowledge training, dengue manual, Computer Assisted Instructor (CAI), test, dengue data, larval indices survey, fish bank, and herbal garden. The seven activities of health provider were knowledge training, dengue manual, CAI, testing, dengue data, larval indices survey, and larval indices program. Three activities for students’ parents included dengue manual, dengue data, and larval indices survey. The 290 students were participating activities in education program and increasing basic knowledge of dengue prevention and control. Comparing the number of correct answers, >80% of students between pre- and post-intervention were found to increase basic knowledge from five correct answers to ten, and of these six items were significantly different (P < 0.001). The two primary schools were continuing non-positive containers (Container Index: CI = 0), but the total larval indices (Breteau Index: BI, House Index: HI, and Container Index: CI) of five primary schools showed high levels both pre- and post-intervention in primary schools;whereas, the students’ households showed high level of BI, HI and CI both pre- and post-intervention (754, 77, and 35 to 616, 81, and 32). Conclusion: The program was needed to continue in primary school and participate from health teacher, health provider, and students’ parents in order to be of great benefit for students.展开更多

The CLIMATE Schools: Alcohol Module was developed to overcome some of the obstacles to high fidelity program implementation. This paper details this development of the CLIMATE Schools: Alcohol Module. The development involved two stages, both of which were considered essential. The first stage, involved reviewing the literature to ensure the program was based on the most effecttive pedagogy and health promotion practice and the second stage involved collaborating with teachers, students and specialists in the area of alcohol and other drugs, to ensure these goals were realised. The final CLIMATE Schools: Alcohol Module consists of computer-driven harm minimisation program which is based on a social influence approach. The program consists of six lessons, each with two components. The first component involves students completing an interactive computer-based program, with the second consisting of a variety of individual, small group and class-based activities. This program was developed to provide an innovative new platform for the delivery of drug education and has proven to be both feasible and effective in the school environment. The success of this program is considered to be testament to this collaborative development approach.展开更多

School feeding programs with fortified biscuits have been evaluated in Bangladesh. However, the impacts of a school meal program using local foods on the growth and nutritional status of children have not been investigated. Objective: To determine whether a school meal program (SMP) using local foods with soybean could improve children’s growth and micronutrient status in rural Bangladesh. Methods: Two primary schools were randomly assigned as intervention (SMP;n = 200) and control (non-SMP;n = 200) schools. Children in the intervention school were supplied a school meal with local foods including soybean, containing more than one-third of the recommended daily allowance of energy and nutrients, 5 days/week for 8 months. The attendance rate and school lunch consumption of the children were monitored. Baseline and final anthropometry, hemoglobin and micronutrient status were assessed. Results: There were no significant differences in anthropometric measurements at baseline between the intervention and control groups, but there were differences in the prevalence of anemia, vitamin A deficiency and zinc deficiency. After the intervention, children in the SMP school showed a larger degree of improvement in the height-for-age Z-score (P Conclusion: A school meal program using local foods with soybean improved the height velocity and hemoglobin concentration of children in rural Bangladesh.展开更多

A secondary aim was to determine the acceptability of the SCP. Participants in the SCP (n = 34;89%) participated in a 10-week case study (age = 13.7 ± 1.16;58% girls). Systematic observations of SCP sessions were conducted to determine physical activity levels and a life skills questionnaire was implemented. Acceptability measures included retention, implementation, attendance rates, and interviews with participants [n = 18] and key stakeholders [n = 6]. Systematic observations indicated that Indigenous students were engaged in MVPA for 58% of lesson time. Participants’ life skills remained unchanged (p = 0.93). Interview data showed that Indigenous students and key stakeholders believed the SCP was acceptable. This study highlights the need for partnerships between Indigenous community organisations and schools to design sport-based programs to promote Indigenous adolescents’ MVPA.展开更多

As such, there is a necessity to engage adolescents in planning and decision-making processes that will affect their future health. This paper describes the need for more innovative and transversal actions, starting from the utility of a multidisciplinary and systemic approach to health. One way in which this can be achieved is by shifting adolescent health programs (AHPs) from a clinically oriented to an education-based model. In particular, AHPs need to consider a personalized and systemic approach to the well-being of adolescents in order to potentiate their strengths and improve weaknesses, enhancing self-esteem, empowerment, and resilience. This is in line with the complexity of human physiology and psychology, as well as scientific evidence showing that several factors significantly influence health status including lifestyle, social context, emotional experiences, and cognitive skills, as demonstrated by the AVATAR Project (“A new purpose for promotion and eVAluation of healTh and well-being Among healthy teenageRs”). This project—which provides a new framework for AHPs—was carried out in Italy and enrolled healthy students as subjects, and aimed to promote well-being in adolescents using a systemic and multistake-holder approach that involved creating a network composed of the different figures and environments around adolescents and moving toward a more school-based and student-centered approach to adolescent health education.展开更多

The 3 + 4 Pilot Program (three-year secondary vocational education and four-year undergraduate education) has been under experiment since 2014. It has attracted more and more academically good junior middle school graduates to secondary vocational schools with the national and local favorable policies and laws. Except the three-year’s hand-on practice, what appeals most to the junior middle school graduates is the academic transfer under the Program, a breakthrough in history of vocation education in China. However, only initiating a new program is not enough. Shanghai government should map out a long-term plan to set up promotion to increase the public awareness to change the long prevailing outdated ideology in order to add more to its appeal of the Program. There is still much work to be done before expanding the scope of the Program.展开更多

This was a qualitative cross-sectional study with 83 adolescents from a public school in the city of S?o Paulo. The participants answered the following question: During the school break do you usually eat or drink something? Please justify your answer. The adolescents’ answers were analyzed through a Brazilian qualitative technique called Discourse of the Collective Subject. The ideas were: School Meal Program (36.2%), don’t eat anything (26.7%), bring from other establishments (20.1%) and drink water or juice (17.1%). The adolescents who chose the School Meal Program claimed they had no other options. On the other hand, the participants who refused the meal did so because they disliked it and as a result brought snacks from home or food markets. The Discourse of the Collective Subject helps the investigator to understand the ideas related to food and nutrition of a collectivity.展开更多
