'Pro-tobacco propaganda': a case study of tobacco industry-sponsored elementary schools in China.

BACKGROUND: China is the largest producer and consumer of tobacco products worldwide. While direct marketing and advertisement of tobacco products is restricted, indirect marketing still exists under the guise of sponsorship and corporate social responsibility (CSR). This case study is focused on tobacco industry-sponsored elementary schools in Chinese rural areas. METHODS: Field visits were conducted in Yunnan province to interview students, teachers, school principals and parents to understand their perceptions of the tobacco industry and its sponsorship of schools. Interviews with tobacco control activists were conducted in Beijing to discuss national tobacco control efforts targeting tobacco industry sponsorship. Interview data were transcribed and coded, with key themes developed using thematic analysis. RESULTS: While health consequences of smoking are generally known, attitudes towards the tobacco industry and its CSR activities remain positive among the general public. Educators and parents do not perceive any impacts on schoolchildren from exposure to 'pro-tobacco propaganda' created by the industry's CSR activities. Attitudes among tobacco control activists were drastically different, with consensus that CSR activities constitute indirect marketing attempts that should be banned. CONCLUSION: National tobacco control legislation banning all forms of indirect marketing including CSR is needed in order to protect the health of future generations.

Association between cumulating substances use and cumulating several school, violence and mental health difficulties in early adolescents.

Multiple substances (alcohol, tobacco, cannabis and other illicit drugs (OID)) have been frequently used in early adolescents maybe due to school, violence and mental-health difficulties. We investigated the associations between substance-use patterns and related difficulties among 1559 middle-school adolescents from north-eastern France (mean age 13.5 ±â€¯1.3). They completed a questionnaire including socioeconomic features, school, violence and mental-health difficulties (school grade repetition, sustained physical/verbal violence, sexual abuse, perpetrated violence, poor social support, depressive symptoms and suicide attempt; cumulated number noted SVMDscore) and the time of their first occurrence during the life course. Data were analyzed using logistic and negative binomial regression models. Alcohol, tobacco, cannabis and OID use affected 35.2, 11.2, 5.6 and 2.8% of the subjects respectively. The risk of using tobacco only, alcohol and tobacco, alcohol plus tobacco and cannabis, or all alcohol, tobacco, cannabis and OID strongly increased with the SVMDscore (socioeconomic features-adjusted odds ratio reaching 85). The risk began in early years in middle schools and then steadily increased, more markedly for elevated SVMDscore. Exposure to several SVMDs may be a transmission vector towards the substance use, starting mostly with alcohol/tobacco, and then shifting to cannabis/OID. These findings help to understand substance-use risk patterns and identify at-risk adolescents.

Children Learning About Secondhand Smoke (CLASS II): A Pilot Cluster Randomized Controlled Trial.

INTRODUCTION: Children exposed to secondhand smoke (SHS) are at increased risk of respiratory illnesses. We piloted a Smoke Free Intervention (SFI) and trial methods before investigating its effectiveness and cost-effectiveness in primary school children. METHODS: In a pilot cluster randomized controlled trial in Bangladesh, primary schools were allocated to usual education (control) or SFI, using minimization. Year-5 children were recruited. Masking treatment allocation was not possible. Delivered by schoolteachers, SFI consisted of two 45-min and four 15-min educational sessions. Our primary outcome was SHS exposure at two months post randomization, verified by children's salivary cotinine. The trial is registered at ISRCTN.com; ISRCTN68690577. RESULTS: Between April 1, 2015 and June 30, 2015, we recruited 12 schools. Of the 484 children present in Year-5, 481 consented. Six schools were allocated to both SFI (n = 245) and to usual education only (n = 236). Of them, 450 children (SFI = 229; control = 221) who had cotinine levels indicative of SHS exposure were followed-up. All schools were retained, 91% children (208/229) in SFI and 88% (194/221) in the control arm completed primary outcome assessment. Their mean cotinine at the cluster level was 0.53 ng/ml (SD 0.36) in SFI and 1.84 ng/ml (SD 1.49) in the control arm-a mean difference of -1.31 ng/ml (95% CI = -2.86 to 0.24). CONCLUSION: It was feasible to recruit, randomize, and retain primary schools and children in our trial. Our study, though not powered to detect differences in mean cotinine between the two arms, provides estimates to inform the likely effect size for future trials. IMPLICATIONS: In countries with high smoking prevalence, children remain at risk of many conditions due to secondhand smoke exposure. There is little empirical evidence on the effectiveness and cost-effectiveness of interventions that can reduce their exposure to secondhand smoke at homes. CLASS II trial found that a school-based intervention (SFI) has the potential to reduce children's exposure to SHS-an approach that has been rarely used, but has considerable merit in school-based contexts. CLASS II trial provides key information to conduct a future definitive trial in this area of public health, which despite its importance has so far received little attention.

Alimentação escolar e agricultura familiar: análise de recursos empregados na compra de alimentos / School meals and family farming: analysis of funds spent in food purchases / Alimentación escolar y agricultura familiar: análisis de recursos empleados en la compra de alimentos

Resumo: O objetivo do estudo foi verificar a adequação da utilização de recursos financeiros para a compra de alimentos provenientes da agricultura familiar no âmbito do Programa Nacional de Alimentação Escolar (PNAE) nas capitais de estados brasileiros e no Distrito Federal. Estudo descritivo, com análise de dados secundários obtidos na página eletrônica do Fundo Nacional de Desenvolvimento para a Educação (FNDE) no espaço dedicado às informações sobre agricultura familiar. Foram investigados os valores repassados pelo FNDE e percentual utilizado na compra de alimentos da agricultura familiar para aquisição de alimentação escolar em capitais dos estados brasileiros e no Distrito Federal no período de 2011 a 2017. Os dados foram coletados em maio de 2019. Das 27 cidades avaliadas, cerca de um terço (33,3%) apresentou compra acima do mínimo recomendado (30%). A Região Norte cumpriu o recomendado (39,4%) enquanto a Sudeste apresentou a menor porcentagem de compra (6,4%). De 2011 a 2017, percebeu-se aumento nos valores totais investidos e no número de cidades compradoras de alimentos da agricultura familiar. Dentre as capitais avaliadas, Boa Vista (Roraima) foi a que mais utilizou recursos para a aquisição de alimentos da agricultura familiar (56,6%). Em 2017, as prefeituras de Boa Vista e Aracaju (Sergipe) ofereceram contrapartida financeira adicionada aos recursos fornecidos pelo FNDE para a compra desses alimentos. Concluiu-se que, no período de 2011 a 2017, apenas um terço das capitais avaliadas utilizou adequadamente a porcentagem de recursos financeiros para a compra de alimentos da agricultura familiar, embora tenha sido percebido aumento gradual na compra desses alimentos, especialmente nas capitais do Norte e Nordeste do Brasil.

Abstract: The study aimed to verify the adequacy of funds for food purchases from family farming in the scope of the National School Food Program (PNAE) in Brazil's state capitals and the Federal District. This was a descriptive study based on secondary data obtained from the webpage of the National Fund for the Development of Education (FNDE) in the link dedicated to information on family farming. We analyzed the amounts transferred to the FNDE and the percentage used in purchasing foods from family farmers for school meals in the state capitals and Federal District from 2011 to 2017. Data were collected in May 2019. One-third of the 27 cities (33.3%) reported purchases above the minimum recommended level (30%). The North of Brazil complied with the recommended level (39.4%), while the Southeast reported the lowest level (6.4%). There was an increase from 2011 to 2017 in the total amounts invested and in the number of cities that purchased foods from family farming. Boa Vista (Roraima) was the capital that spent the largest share of its school meal funds on foods produced by family farmers (56.6%). In 2017, the local governments in Boa Vista and Aracaju (Sergipe) offered matching funds for the funds transferred from the FNDE for these food purchases. In conclusion, from 2011 to 2017, only one-third of the capital cities adequately used the percentage of funds for purchasing foods from family farming, although there was a gradual increase in the purchase of these foods, especially in the state capitals from North and Northeast Brazil.

Resumen: El objetivo de este estudio fue verificar la adecuación de la utilización de recursos financieros para la compra de alimentos procedentes de la agricultura familiar, dentro del ámbito del Programa Nacional de Alimentación Escolar (PNAE), en capitales de estados brasileños y en el Distrito Federal. Se trata de un estudio descriptivo con análisis de datos secundarios, obtenidos de la página electrónica del Fondo Nacional de Desarrollo para la Educación (FNDE), dentro de la sección dedicada a la información sobre agricultura familiar. Se investigaron los valores proporcionados por el FNDE y el porcentaje destinado a la compra de alimentos de agricultura familiar para la adquisición en escuelas de capitales de estados brasileños, así como en el Distrito Federal, durante el período de 2011 a 2017. Los datos se recogieron en mayo de 2019. De las 27 ciudades evaluadas, cerca de un tercio (33,3%) presentó una compra por encima del mínimo recomendado (30%). La Región Norte cumplió lo recomendado (39,4%), mientras que la Sudeste presentó el menor porcentaje de compra (6,4%). De 2011 a 2017, se percibió un aumento en los valores totales invertidos y en el número de ciudades compradoras de alimentos procedentes de agricultura familiar. Entre las capitales evaluadas, Boa Vista (Roraima) fue la que más utilizó recursos para la adquisición de alimentos de agricultura familiar (56,6%). En 2017, los ayuntamientos de Boa Vista y Aracaju (Sergipe) ofrecieron una partida financiera adicional, además de los recursos proporcionados por el FNDE, para la compra de estos alimentos. Se concluye que, durante el período de 2011 a 2017, solamente un tercio de las capitales evaluadas utilizó adecuadamente el porcentaje de recursos financieros para la compra de alimentos de la agricultura familiar, aunque se haya percibido un aumento gradual en la compra de estos alimentos, especialmente en las capitales del Norte y Nordeste de Brasil.

Effectiveness of the 'Girls Active' school-based physical activity programme: A cluster randomised controlled trial.

BACKGROUND: Globally, adolescent girls' physical activity (PA) levels are low. The 'Girls Active' secondary school-based programme, developed by the Youth Sport Trust, aims to increase PA in adolescent girls. This paper explores the effectiveness of the 'Girls Active' school-based PA programme. METHODS: A random sample of girls aged 11-14 from 20 secondary schools (Midlands, UK) participated in a two-arm cluster randomised controlled trial. Ten schools received Girls Active and 10 continued with usual practice. Measurements were taken at baseline, seven- and 14-month follow-up. PRIMARY OUTCOME: wrist-worn accelerometer measured moderate- to vigorous-intensity PA (MVPA). SECONDARY OUTCOMES: overall PA, light PA, sedentary time, body composition, and psychosocial outcomes. Generalised estimating equations, adjusted for school cluster and potential confounders, were used and A priori subgroup analysis was undertaken. Micro-costing and cost-consequence analyses were conducted using bespoke collection methods on programme delivery information. Outcomes for the cost-consequence analysis were health related quality of life measured by the Child Health Utility-9D and service use. RESULTS: Overall, 1752 pupils participated, 1211 (69.1%) provided valid 14-month accelerometer data. No difference in MVPA (mins/day; 95% confidence intervals) was found at 14 months (1.7; -0.8 to 4.3), there was at seven months (2.4; 0.1 to 4.7). Subgroup analyses showed significant intervention effects on 14-month in larger schools (3.9; 1.39 to 6.09) and in White Europeans (3.1; 0.60 to 6.02) and in early maturers (5.1; 1.69 to 8.48) at seven months. The control group did better in smaller schools at 14-months (-4.38; -7.34 to -1.41). Significant group differences were found in 14-month identified motivation (-0.09; -0.18 to -0.01) and at seven months in: overall PA (1.39 mg/day; 0.1 to 2.2), after-school sedentary time (-4.7; -8.9 to -0.6), whole day (5.7; 1.0 to 10.5) and school day (4.5; 0.25 to 8.75) light PA, self-esteem. Small, statistically significant, differences in some psychosocial variables favoured control schools. Micro-costing demonstrated that delivering the programme resulted in a range of time and financial costs at each school. Cost-consequence analysis demonstrated no effect of the programme for health related quality of life or service use. CONCLUSIONS: Compared with usual practice, 'Girls Active' did not affect 14-month MVPA. TRIAL REGISTRATION: ISRCTN10688342.

Exploring the factors affecting the implementation of tobacco and substance use interventions within a secondary school setting: a systematic review.

BACKGROUND: The aim of this mixed-methods, systematic literature review was to develop an understanding of the factors affecting the implementation of tobacco and substance use intervention programmes in the secondary school setting using NPT as an analytical framework. METHODS: A search strategy was developed that combined implementation, school and intervention search terms. Literature searches were conducted in MEDLINE, Embase, PsycHINFO, Scopus, ERIC, CINAHL, Web of Science and the Cochrane Library. PROSPERO was also searched for similar systematic reviews and a grey literature search of policy documents and relevant material was also conducted. Papers were eligible for inclusion if they were based in a secondary school and focused on the implementation of a tobacco or substance use programme. Both quantitative and qualitative methodologies were considered for inclusion. Normalisation Process Theory (NPT) was used as a conceptual framework to identify facilitators and barriers of implementation and to structure the synthesis. RESULTS: Inclusion criteria were met by 15 papers. The included papers were both quantitative and qualitative and focused on a range of tobacco and substance use interventions, delivered by differing providers. Key facilitating factors for implementation were positive organisational climate, adequate training and teacher's and pupil's motivation. Barriers to implementation included heavy workloads, budget cuts and lack of resources or support. Quality appraisal identified papers to be of moderate to weak quality, as papers generally lacked detail. CONCLUSION: NPT highlighted the need for studies to extend their focus to include reflexive monitoring around appraisal and the evaluation processes of implementing new tobacco or substance use programs. Future research should also focus on employing implementation theory as a tool to facilitate bridging the gap between school health research and practice.

The Saskatchewan/New Brunswick Healthy Start-Départ Santé intervention: implementation cost estimates of a physical activity and healthy eating intervention in early learning centers.

BACKGROUND: Participation in daily physical activity and consuming a balanced diet high in fruits and vegetables and low in processed foods are behaviours associated with positive health outcomes during all stages of life. Previous literature suggests that the earlier these behaviours are established the greater the health benefits. As such, early learning settings have been shown to provide an effective avenue for exploring and influencing the physical activity and healthy eating behaviours of children before school entry. However, in addition to improving individual level health of children, such interventions may also result in a number of social benefits for the society. In fact, research among adult populations has shown that sufficient participation in physical activity can significantly lower hospital stays and physician visits, in turn leading to positive economic outcomes. To our knowledge there is very limited literature about economic evaluations of interventions implemented in early learning centers to increase physical activity and healthy eating behaviours among children. The primary purpose of this paper is to identify inputs and costs needed to implement a physical activity and healthy eating intervention (Healthy Start-Départ Santé (HS-DS)) in early learning centres throughout Saskatchewan and New Brunswick over the course of three years. In doing so, implementation cost is estimated to complete the first phase of a social return on investment analysis of this intervention. METHODS: In order to carry out this evaluation the first step was to identify the inputs and costs needed to implement the intervention, along with the corresponding outputs. With stakeholder interviews and using existing database, we estimated the implementation cost by measuring, valuing and monetizing each individual input. RESULTS: Our results show that the total annual cost of implementing HS-DS was $378,753 in the first year, this total cost decreased slightly in the second year ($356,861) and again in the third year ($312,179). On average, the total annual cost is about $350,000 which implies an annual cost of $285 per child. Among all inputs, time-cost accounted for the larger share of total resources need to implement the intervention. Overall, administration and support services accounted for the largest portion of the total implementation cost each year: 74% (year 1), 79% (year 2), and 75% (year 3). CONCLUSIONS: The results from this study shed lights for future implementation of similar interventions in this context. It also helps to assess the cost effectiveness of future interventions.

Evaluation of a Urine Pooling Strategy for the Rapid and Cost-Efficient Prevalence Classification of Schistosomiasis.

BACKGROUND: A key epidemiologic feature of schistosomiasis is its focal distribution, which has important implications for the spatial targeting of preventive chemotherapy programs. We evaluated the diagnostic accuracy of a urine pooling strategy using a point-of-care circulating cathodic antigen (POC-CCA) cassette test for detection of Schistosoma mansoni, and employed simulation modeling to test the classification accuracy and efficiency of this strategy in determining where preventive chemotherapy is needed in low-endemicity settings. METHODOLOGY: We performed a cross-sectional study involving 114 children aged 6-15 years in six neighborhoods in Azaguié Ahoua, south Côte d'Ivoire to characterize the sensitivity and specificity of the POC-CCA cassette test with urine samples that were tested individually and in pools of 4, 8, and 12. We used a Bayesian latent class model to estimate test characteristics for individual POC-CCA and quadruplicate Kato-Katz thick smears on stool samples. We then developed a microsimulation model and used lot quality assurance sampling to test the performance, number of tests, and total cost per school for each pooled testing strategy to predict the binary need for school-based preventive chemotherapy using a 10% prevalence threshold for treatment. PRINCIPAL FINDINGS: The sensitivity of the urine pooling strategy for S. mansoni diagnosis using pool sizes of 4, 8, and 12 was 85.9%, 79.5%, and 65.4%, respectively, when POC-CCA trace results were considered positive, and 61.5%, 47.4%, and 30.8% when POC-CCA trace results were considered negative. The modeled specificity ranged from 94.0-97.7% for the urine pooling strategies (when POC-CCA trace results were considered negative). The urine pooling strategy, regardless of the pool size, gave comparable and often superior classification performance to stool microscopy for the same number of tests. The urine pooling strategy with a pool size of 4 reduced the number of tests and total cost compared to classical stool microscopy. CONCLUSIONS/SIGNIFICANCE: This study introduces a method for rapid and efficient S. mansoni prevalence estimation through examining pooled urine samples with POC-CCA as an alternative to widely used stool microscopy.

Drug Testing US Student-Athletes for Performance-Enhancing Substance Misuse: A Flawed Process.

The author argues that drug testing of U.S. high school students for performance-enhancing substance misuse is invasive, expensive, and the low number of positive test results do not justify the costs, especially in financially strapped school districts where this money would be better spent on injury prevention for athletes and the education of all students.

Literature research of the Nutrition Improvement Programme for Rural Compulsory Education Students in China.

OBJECTIVE: To describe the Nutrition Improvement Programme for Rural Compulsory Education Students (NIPRCES) in China and to share the experiences of developing and implementing nationwide school meal programmes with other countries. DESIGN: The article is based on a literature review of technical documents and reports of NIPRCES and relevant national legislation, technical reports and studies on school nutrition, minutes of meetings and national conferences, and official documents of the National Office of Student Nutrition and the Chinese Center for Disease Control and Prevention. SETTING: People's Republic of China. SUBJECTS: Published papers, national policies, legislation and unpublished official documents. RESULTS: A total of 23 million rural compulsory education students were covered by NIPRCES. In the development and implementation process of NIPRCES, fifteen ministries and national committees were involved and an efficient collaborative mechanism was established. All NIPRCES-covered schools were required to serve meals on a daily basis. By the end of June 2012, the proportions of students choosing 'school feeding', 'food package' and 'family feeding' modes were respectively 64.0 %, 32.0 % and 4.0 %. The central government subsidized school meals annually by more than $US 2.5 billion and invested $US 4.8 billion on school kitchens to support this programme. CONCLUSIONS: The NIPRCES is a significant movement of governmental nutritional intervention in China. Food safety, financial security, decentralization and other potential concerns should be considered and lessons can be learned from other countries. Further relevant research and a nationwide monitoring and evaluation programme are needed.

Childhood secondhand smoke exposure and ADHD-attributable costs to the health and education system.

BACKGROUND: Children exposed to secondhand smoke (SHS) have higher rates of behavioral and cognitive effects, including attention deficit hyperactivity disorder (ADHD), but the costs to the health care and education systems have not been estimated. We estimate these costs for school-aged children aged 5-15. METHODS: The relative risk (RR) of ADHD from SHS exposure was obtained from our previous work. SHS exposure was measured using 2 alternative approaches--reported exposure and serum cotinine-measured exposure. RRs and SHS exposure were used to determine the number of children with SHS-attributable ADHD, and mean costs of ADHD-related health care and education services were applied to obtain SHS-attributable health care and education costs. RESULTS: Annual health care costs of SHS-attributable ADHD ranged from $644 million (using reported SHS exposure) to $2.05 billion (using cotinine-measured exposure). SHS-attributable costs to the education system ranged from $2.90 to $9.23 billion. CONCLUSIONS: The costs of SHS-attributable ADHD to the education system may total more than 4 times the costs for health care. The huge economic impact of SHS exposure on the education system has not been documented previously, and suggests that reducing childhood exposure to tobacco smoke will release substantial funds that could be used for general education of all children.

Implementing a multicomponent school-based obesity prevention intervention: a qualitative study.

OBJECTIVE: To explore barriers and facilitators to implementing and sustaining Healthy Choices, a 3-year multicomponent obesity prevention intervention implemented in middle schools in Massachusetts. METHODS: Using purposive sampling, 56 in-depth interviews were conducted with middle school employees representing different positions (administrators, teachers, food service personnel, and employees serving as intervention coordinators). Interviews were recorded and transcribed. Emergent themes were identified using thematic analyses. RESULTS: State-mandated testing, budget limitations, and time constraints were viewed as implementation barriers, whereas staff buy-in, external support, and technical assistance were seen as facilitating implementation. Respondents thought that intervention sustainability depended on external funding and expert assistance. CONCLUSIONS AND IMPLICATIONS: Results confirm the importance of gaining faculty and staff support. Schools implementing large-scale interventions should consider developing sustainable partnerships with organizations that can provide resources and ongoing training. Sustainability of complex interventions may depend on state-level strategies that provide resources for implementation and technical assistance.

Are school feeding programs in low-income settings sustainable? Insights on the costs of school feeding compared with investments in primary education.

BACKGROUND: School feeding programs are ubiquitous. Benchmarking expenditures for school feeding is an important component of program accountability and sustainability. OBJECTIVE: To analyze the costs of school feeding and the cost relative to education expenditure and other measures of economic growth. METHODS: Data on the costs of school feeding were collected from multiple sources, including United Nations databases, gray literature, and published reviews. Relationships between costs of school feeding, costs of education, and GDP per capita were analyzed through standard linear regression. RESULTS: Data on costs of school feeding were obtained for 74 countries, including 12 high-income, 40 middle-income, and 22 in low-income countries. School feeding programs were found to cost US$173 per child per year, ranging from US$54 in low-income countries to US$693 in high-income countries. In high-income countries, school feeding costs per capita were on average equivalent to 11% of the per capita investments in primary education, compared with 19% in middle-income countries and 68% in low-income countries. In middle- and low-income countries, school feeding programs covered on average 18% and 13% of the children enrolled in primary school, respectively. The total budget for school feeding in low-income countries was found to be on average 11% of the estimated total primary school education budget, compared to 4% in middle-income countries. CONCLUSIONS: School feeding investments are targeted in low- and middle-income settings, reaching only a portion of primary schoolchildren, with total costs only a fraction of the overall investment in education. As countries get richer, school feeding costs become a much smaller proportion of education costs. The findings of this study provide an updated framework for benchmarking school feeding programs.

For-profit colleges.

For-profit, or proprietary, colleges are the fastest-growing postsecondary schools in the nation, enrolling a disproportionately high share of disadvantaged and minority students and those ill-prepared for college. Because these schools, many of them big national chains, derive most of their revenue from taxpayer-funded student financial aid, they are of interest to policy makers not only for the role they play in the higher education spectrum but also for the value they provide their students. In this article, David Deming, Claudia Goldin, and Lawrence Katz look at the students who attend for-profits, the reasons they choose these schools, and student outcomes on a number of broad measures and draw several conclusions. First, the authors write, the evidence shows that public community colleges may provide an equal or better education at lower cost than for-profits. But budget pressures mean that community colleges and other nonselective public institutions may not be able to meet the demand for higher education. Some students unable to get into desired courses and programs at public institutions may face only two alternatives: attendance at a for-profit or no postsecondary education at all. Second, for-profits appear to be at their best with well-defined programs of short duration that prepare students for a specific occupation. But for-profit completion rates, default rates, and labor market outcomes for students seeking associate's or higher degrees compare unfavorably with those of public postsecondary institutions. In principle, taxpayer investment in student aid should be accompanied by scrutiny concerning whether students complete their course of study and subsequently earn enough to justify the investment and pay back their student loans. Designing appropriate regulations to help students navigate the market for higher education has proven to be a challenge because of the great variation in student goals and types of programs. Ensuring that potential students have complete and objective information about the costs and expected benefits of for-profit programs could improve postsecondary education opportunities for disadvantaged students and counter aggressive and potentially misleading recruitment practices at for-profit colleges, the authors write.

Cost effectiveness of interferon-gamma release assay for school-based tuberculosis screening.

PURPOSE: To assess the cost effectiveness of school-based tuberculosis (TB) screening using QuantiFERON®-TB Gold In-Tube (QFT) versus the tuberculin skin test (TST) and chest x-ray examination (CXR). METHODS: We constructed Markov models of first-year high-school and university students, using a societal perspective, and followed them up until the age of 80 years. Three strategies (QFT, TST, and CXR) were modeled. All costs and clinical benefits were discounted at a fixed annual rate of 3%. RESULTS: In the base-case analyses of 16-year-old high-school students and 19-year-old university students, the QFT strategy yielded the greatest benefits at the lowest cost [in year 2009 values] (16-year-olds: $US627.89, 29.69835 quality-adjusted life-years [QALYs]; 19-year-olds: $US646.04, 29.15361 QALYs), compared with the TST strategy (16-year-olds: $US943.50, 29.69767 QALYs; 19-year-olds: $US998.62, 29.15288 QALYs) and the CXR strategy (16-year-olds: $US7286.24, 29.69532 QALYs; 19-year-olds: $US7305.19, 29.14911 QALYs). On one-way sensitivity analyses, the bacillus Calmette-Guérin (BCG) vaccination rate was not sensitive to the TST strategy. On probabilistic sensitivity analysis, the QFT strategy was the most cost effective, with a willingness-to-pay level of $US50 000/QALY gained. CONCLUSION: The QFT strategy provided the greatest benefits at the lowest cost for school-based TB screening. There appears to be little role for TST or CXR in screening of school populations. Current practices using either TST or CXR screening should be reconsidered on the basis of cost effectiveness.

Middle school vaccination requirements and adolescent vaccination coverage.

OBJECTIVE: To determine if middle school vaccination requirements are associated with higher coverage for adolescent vaccines. METHODS: School entry requirements for receipt of vaccination for school entry or education of parents for 3 vaccines recommended for adolescents: tetanus/diphtheria-containing (Td) or tetanus/diphtheria/acellular pertussis (TdaP), meningococcal conjugate (MenACWY), and human papillomavirus (HPV) vaccines in place for the 2008-2009 school year were reviewed for the 50 states and the District of Columbia. Vaccination coverage levels for adolescents 13 to 17 years of age by state requirement status and change in coverage from 2008 to 2009 were assessed by using the 2008-2009 National Immunization Survey-Teen. RESULTS: For the 2008-2009 school year, 32 states had requirements for Td/TdaP (14 specifically requiring TdaP) and none required education; 3 states required MenACWY vaccine and 10 others required education; and 1 state required HPV vaccine and 5 required education. Compared with states with no requirements, vaccination requirements were associated with significantly higher coverage for MenACWY (71% vs 53%, P < .001) and Td/TdaP (80% vs 70%, P < .001) vaccines. No association was found between education-only requirements and coverage levels for MenACWY and HPV vaccines. States with new 2008-2009 vaccination requirements (n = 6, P = .04) and states with preexisting vaccination requirements (n = 26, P = .02) for Td/TdaP experienced a significant increase in TdaP coverage over states with no requirements. CONCLUSIONS: Middle school vaccination requirements are associated with higher coverage for Td/TdaP and MenACWY vaccines, whereas education-only requirements do not appear to increase coverage levels for MenACWY or HPV vaccines. The impact on coverage should continue to be monitored as more states adopt requirements.

The Active for Life Year 5 (AFLY5) school based cluster randomised controlled trial: study protocol for a randomized controlled trial.

BACKGROUND: Low levels of physical activity, high levels of sedentary behaviour and low levels of fruit and vegetable consumption are common in children and are associated with adverse health outcomes. The aim of this paper is to describe the protocol for a cluster randomised controlled trial (RCT) designed to evaluate a school-based intervention that aims to increase levels of physical activity, decrease sedentary behaviour and increase consumption of fruit and vegetables in school children. METHODS/DESIGN: The Active for Life Year 5 (AFLY5) study is a school-based, cluster RCT that targets school children in Year 5 (age 9-10 years). All state junior/primary schools in the area covered by Bristol City and North Somerset Council are invited to participate; special schools are excluded. Eligible schools are randomised to one of two arms: intervention arm (receive the intervention 2011-2012) and control arm (receive the intervention after the final follow-up assessment, 2013-2014). The primary outcomes of the trial are levels of accelerometer assessed physical activity and sedentary behaviour and questionnaire assessed fruit and vegetable consumption. A number of secondary outcomes will also be measured, including body mass index, waist circumference and overweight/obesity. Outcomes will be assessed at baseline (prior to intervention when the children are in Year 4), at the end of intervention 'immediate follow-up' and '12 months long-term' follow-up. We will use random effects linear and logistic regression models to compare outcomes by randomised arm. The economic evaluation from a societal perspective will take the form of a cost consequence analysis. Data from focus groups and interviews with pupils, parents and teachers will be used to increase understanding of how the intervention has any effect and is integrated into normal school activity. DISCUSSION: The results of the trial will provide information about the public health effectiveness of a school-based intervention aimed at improving levels of physical activity, sedentary behaviour and diet in children. TRIAL REGISTRATION: ISRCTN50133740.

Condição de saúde bucal em escolares de 12 anos de escolas públicas e privadas de Goiânia, Brasil / Oral health in 12 year-old students from public and private schools in the city of Goiânia, Brazil

OBJETIVO: Comparar os alunos de 12 anos das escolas públicas e privadas de Goiânia, Goiás, quanto à prevalência de cárie, condição periodontal, anomalia dentofacial e fluorose. MÉTODOS: Em 2003, o Projeto Condições de Saúde Bucal da População Brasileira 2002-2003 (SB Brasil) foi ampliado para Goiânia na forma de um estudo transversal, descrito neste trabalho. A amostra foi constituída por 1 947 escolares de 12 anos frequentando escolas da zona urbana do Município: 1 790 (91,9 por cento) eram de escolas públicas e 157 (8,1 por cento) de escolas privadas. Através de exame clínico, foram coletados dados sobre as seguintes condições bucais: cárie dentária (índice de dentes cariados, perdidos e obturado, CPOD), condição periodontal (índice periodontal comunitário, CPI), anormalidade dento-facial (índice de estética dental, DAI) e fluorose dentária (índice de Dean). Para comparação entre os grupos foram utilizados os testes do qui-quadrado e U de Mann Whitney. RESULTADOS: Houve diferença entre os tipos de escola para todas as variáveis investigadas. Os escolares de instituições públicas apresentaram índices mais elevados de cárie, condição periodontal e anomalia dentofacial do que aqueles de escolas privadas (P < 0,05). Os escolares de instituições privadas apresentaram maior prevalência de fluorose (P < 0,05). CONCLUSÕES: O tipo de escola foi associado à condição de saúde bucal dos escolares pesquisados. São recomendados investimentos em ações e serviços que busquem minimizar tais desigualdades e seus efeitos como parte das políticas de saúde bucal.

OBJECTIVE: To compare 12-year-old students from public and private schools in the city of Goiânia, Brazil, in terms of the prevalence of caries, periodontal conditions, dentofacial anomalies, and fluorosis. METHODS: In 2003, the 2002-2003 Oral Health Conditions in the Brazilian Population project (SB Brasil) was expanded to Goiânia as a cross-sectional study, as described in the present article. The sample included 1 947 students from urban schools: 1 790 (91.9 percent) attended public schools and 157 (8.1 percent) attended private schools. Data on the following oral conditions were collected through clinical examination: dental caries (decayed, missing, or filled teeth index, DMFT), periodontal condition (Community Periodontal Index, CPI), dentofacial anomaly (Dental Aesthetics Index, DAI), and dental fluorosis (Dean index). The groups were compared using the chi-square and Mann-Whitney U tests. RESULTS: There were differences between the public and private schools for all the variables. DMFT, CPI, and DAI indexes were higher in children from public schools (P < 0.05). Fluorosis was more prevalent in students from private schools (P < 0.05). CONCLUSIONS: The type of school was associated with the oral health condition of the children in this sample. Investments in actions and services to mitigate this inequality and its effects should be made as part of the policies to promote oral health.
