Compulsory vaccination of children - medical and legal problems.

Regarding the vaccination of children, it can be said that there are basically three vaccination policies in the world, one of which is usually used in particular country depending on the national legislation. These are the mandatory vaccination policy, mandatory vaccination policy for school entry and recommended vaccination policy. The mandatory vaccination policy and the mandatory vaccination policy for school entry face obstacles consisting of conflicts between fundamental human rights and freedoms. This is, for example, a conflict between the right to health and the right to life on the one hand and the right to protect the inviolability of the person and body integrity or the right to personal freedom, freedom of movement, residence, etc., on the other. Another issue is the right to undisrupted school attendance, based on both compulsory schooling and the right to education. This article looks at different approaches to the vaccination of children in different countries. It provides an illustrative comparison of approaches to vaccination of children in selected countries. It is obvious that the essential problems with organizing and ensuring the vaccination of children are and will be associated with the indicated conflicts of fundamental human rights. It is therefore necessary to search and try to find the optimal policy for undergoing the necessary vaccinations and thereby creating herd immunity, of course for those infectious diseases where this is possible. These efforts are necessary for sufficiently effective protection of individual and public health.

Kindergarten Vaccination Status in California After Changes to Medical Exemption Policy.

This study evaluates changes in medical exemptions and geographic distribution of kindergarteners in California not up to date on vaccination after changes to state legislation.

Lifting Universal Masking in Schools - Covid-19 Incidence among Students and Staff.

BACKGROUND: In February 2022, Massachusetts rescinded a statewide universal masking policy in public schools, and many Massachusetts school districts lifted masking requirements during the subsequent weeks. In the greater Boston area, only two school districts - the Boston and neighboring Chelsea districts - sustained masking requirements through June 2022. The staggered lifting of masking requirements provided an opportunity to examine the effect of universal masking policies on the incidence of coronavirus disease 2019 (Covid-19) in schools. METHODS: We used a difference-in-differences analysis for staggered policy implementation to compare the incidence of Covid-19 among students and staff in school districts in the greater Boston area that lifted masking requirements with the incidence in districts that sustained masking requirements during the 2021-2022 school year. Characteristics of the school districts were also compared. RESULTS: Before the statewide masking policy was rescinded, trends in the incidence of Covid-19 were similar across school districts. During the 15 weeks after the statewide masking policy was rescinded, the lifting of masking requirements was associated with an additional 44.9 cases per 1000 students and staff (95% confidence interval, 32.6 to 57.1), which corresponded to an estimated 11,901 cases and to 29.4% of the cases in all districts during that time. Districts that chose to sustain masking requirements longer tended to have school buildings that were older and in worse condition and to have more students per classroom than districts that chose to lift masking requirements earlier. In addition, these districts had higher percentages of low-income students, students with disabilities, and students who were English-language learners, as well as higher percentages of Black and Latinx students and staff. Our results support universal masking as an important strategy for reducing Covid-19 incidence in schools and loss of in-person school days. As such, we believe that universal masking may be especially useful for mitigating effects of structural racism in schools, including potential deepening of educational inequities. CONCLUSIONS: Among school districts in the greater Boston area, the lifting of masking requirements was associated with an additional 44.9 Covid-19 cases per 1000 students and staff during the 15 weeks after the statewide masking policy was rescinded.

Cannabis use and suicidal ideation among youth: Can we democratize school policies using digital citizen science?

BACKGROUND: School policies and programs are important in preventing Cannabis use among youth. This study uses an innovative digital citizen science approach to determine the association between Cannabis use and suicidal ideation among youth while investigating how school health policies mediate this association. METHODS: The study engaged 818 youth (aged 13-18 years) and 27 educators as citizen scientists via their own smartphones. Youths responded to time-triggered validated surveys and ecological momentary assessments to report on a complex set of health behaviours and outcomes. Similarly, educators' reported on substance misuse and mental health school policies and programs. Multivariable logistic regression modeling and mediation analyses were employed. RESULTS: 412 youth provided data on substance misuse and suicidal ideation. Cannabis use and other factors such as bullying, other illicit drug use, and youth who identified as females or other gender were associated with increased suicidal ideation. However, school policies and programs for substance misuse prevention did not mediate the association between Cannabis use and suicidal ideation. CONCLUSIONS: In the digital age, it is critical to reimagine the role of schools in health policy interventions. Digital citizen science not only provides an opportunity to democratize school policymaking and implementation processes, but also provides a voice to vulnerable youth.

Evaluation of Trends in Homeschooling Rates After Elimination of Nonmedical Exemptions to Childhood Immunizations in California, 2012-2020.

Introduction: In 2015, California passed Senate Bill No. 277 (SB 277) and became the first state in more than 30 years to eliminate nonmedical exemptions to mandatory childhood immunizations for school entry. One concern that emerged was that the law created an incentive for parents to remove children from brick-and-mortar schools to bypass the immunization requirements. Objective: To assess the trends in homeschooling rates after the elimination of nonmedical exemptions to the requirement of childhood immunizations for school entry. Design, Setting, and Participants: This preintervention-postintervention cross-sectional study calculated homeschooling rates as the number of students in kindergarten through grade 8 (K-8) enrolled through each of California's 3 homeschooling mechanisms (independent study program, private school affidavit, and private school satellite program) divided by all K-8 students enrolled in the same academic year. Data on homeschooling rates were obtained from the California Department of Education. Interrupted time series analyses were conducted using a linear regression model in which the outcome variable was the percentage of students enrolled in a homeschool program before and after SB 277. Data were collected and analyzed from October 3, 2012, to October 2, 2019. Intervention: Passage of SB 277, which eliminated nonmedical exemptions to childhood immunizations for school entry. Main Outcomes and Measures: Homeschooling rates for K-8 students. Results: Among the students included in the analysis, the homeschooling enrollment for K-8 students in California increased from 35 122 students (0.8%) during the 2012-2013 school year to 86 574 students (1.9%) during the 2019-2020 school year; however, the implementation of SB 277 was not associated with an increase in the percentage of students enrolled in homeschooling programs in California beyond the secular trend. The increase in homeschooling was greatest for the lower grade levels: kindergarten homeschooling enrollment increased from 2068 students (0.4%) in the 2012-2013 school year to 10 553 students (1.9%) in the 2019-2020 school year, whereas the grade 8 homeschool enrollment rate increased from 5146 students (1.0%) in the 2012-2013 school year to 10 485 students (2.0%) in the 2019-2020 school year. Independent study programs accounted for 20 149 students (45.3%) of homeschooling enrollment, private school affidavits accounted for 19 333 students (43.5%), and private school satellite programs accounted for 4935 students (11.1%) during the 2015-2016 school year. Conclusions and Relevance: The findings of this study suggest that legislative action to limit nonmedical exemptions for compulsory vaccination for school entry is not associated with removal of students from classroom-based instruction in brick-and-mortar institutions.

Food commercialization in schools: analysis of the regulatory process in Brazil / Comercialização de alimentos em escolas: análise do processo de regulamentação no Brasil

ABSTRACT Objective To identify and to describe the legal provisions that regulate the sale of food in Brazilian schools. Method Documentary analysis carried out in 2019, on the websites of the State, capital and Federal District Legislative Assemblies, via e-mail and/or telephone contact and publications on the subject review. The data were grouped by geographic region and a descriptive analysis was carried out. Results Data were obtained from 96% of the federative units (25 States and the Federal District). 62 legal provisions were found: 60% current, 11% revoked and 29% draft bills. Current legislation was found in 67% of States: 100% of the States in the South, Southeast and Center-West regions, 56% in the Northeast and 43% in the North. Most of the legal provisions prohibit the sale of ultra-processed foods and encourage the sale of fruits and fresh foods in the public and private school network. Conclusion Progress is observed in the school food regulatory process in this country, considering its coverage in the States and in the public and private school network, but still restricted to the South, Southeast and Midwest regions.

In the Wake of a Pandemic: Revisiting School Approaches to Nonmedical Exemptions to Mandatory Vaccination in the US.

Mandatory school vaccination policies with exclusion of unvaccinated students can be a powerful tool in ensuring high vaccination rates. Some parents may object to mandatory vaccination policies, claiming exemptions based on medical, religious, or philosophical reasons. Individual schools, school systems, or local or regional governments have different policies with respect to whether, and what kind of, exemptions may be allowed. In the setting of the current pandemic, questions regarding the acceptability of exemptions have resurfaced, as schools and local governments struggle with how to safely return children to school. Anticipating that school attendance will be facilitated by the development of a vaccine, school systems will face decisions about whether to mandate vaccination and whether to permit exemptions. The American Academy of Pediatrics promulgates policy favoring the elimination of nonmedical exemptions generally in schools. This discussion considers whether schools should eliminate nonmedical exemptions to vaccination as proposed in the American Academy of Pediatrics policy, ultimately concluding that broad elimination of exemptions is not justified and advocating a more nuanced approach that encourages school attendance while promoting vaccination and broader public health goals.

The evidence for the impact of policy on physical activity outcomes within the school setting: A systematic review.

BACKGROUND: Despite the well-established health benefits of physical activity (PA) for young people (aged 4-19 years), most do not meet PA guidelines. Policies that support PA in schools may be promising, but their impact on PA behavior is poorly understood. The aim of this systematic review was to ascertain the level and type of evidence reported in the international scientific literature for policies within the school setting that contribute directly or indirectly to increasing PA. METHODS: This systematic review is compliant with Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Six databases were searched using key concepts of policy, school, evaluation, and PA. Following title and abstract screening of 2323 studies, 25 progressed to data synthesis. Methodological quality was assessed using standardized tools, and the strength of the evidence of policy impact was described based on pre-determined codes: positive, negative, inconclusive, or untested statistically. RESULTS: Evidence emerged for 9 policy areas that had a direct or indirect effect on PA within the school setting. These were whole school PA policy, physical education, sport/extracurricular PA, classroom-based PA, active breaks/recess, physical environment, shared use agreements, active school transport, and surveillance. The bulk of the evidence was significantly positive (54%), 27% was inconclusive, 9% was significantly negative, and 11% was untested (due to rounding, some numbers add to 99% or 101%). Frequency of evidence was highest in the primary setting (41%), 34% in the secondary setting, and 24% in primary/secondary combined school settings. By policy area, frequency of evidence was highest for sport/extracurricular PA (35%), 17% for physical education, and 12% for whole school PA policy, with evidence for shared use agreements between schools and local communities rarely reported (2%). Comparing relative strength of evidence, the evidence for shared use agreements, though sparse, was 100% positive, while 60% of the evidence for whole school PA policy, 59% of the evidence for sport/extracurricular PA, 57% of the evidence for physical education, 50% of the evidence for PA in classroom, and 50% of the evidence for active breaks/recess were positive. CONCLUSION: The current evidence base supports the effectiveness of PA policy actions within the school setting but cautions against a "one-size-fits-all" approach and emphasizes the need to examine policy implementation to maximize translation into practice. Greater clarity regarding terminology, measurement, and methods for evaluation of policy interventions is needed.

The Emergence of Spatial Clustering in Medical Vaccine Exemptions Following California Senate Bill 277, 2015-2018.

Objectives. To understand how the elimination of nonmedical vaccine exemptions through California Senate Bill 277 (SB277) may have resulted in increased spatial clustering of medical exemptions.Methods. We used spatial scan statistics and negative binomial regression models to examine spatial clustering in medical vaccine exemptions in California kindergartens from 2015 to 2018.Results. Spatial clustering of medical exemptions across schools emerged following SB277. Clusters were located in similar geographic areas to previous clusters of nonmedical vaccine exemptions, suggesting a spatial association between high nonmedical exemption prevalence and increasing rates of medical exemptions. Regression results confirmed this positive association at the local level. The sociodemographic characteristics of the neighborhoods in which schools were located explained some, but not all, of the positive spatial associations between exemptions before and after SB277.Conclusions. Elimination of nonmedical vaccine exemptions via SB277 may have prompted some parents to instead seek medical exemptions to required school vaccines. The spatial association of these 2 types of exemptions has implications for maintaining pockets of low vaccine compliance and increased disease transmission.

Preventing Asthma Emergencies in Schools.

Asthma is a significant public health issue, impacting quality of life, morbidity, and health care costs nationally. Stock asthma rescue medication policies authorize school districts to maintain unassigned albuterol and enable trained staff members to administer the medication in response to asthma symptoms, exercise premedication, and asthma emergencies. Stock asthma rescue (or reliever) medication laws serve as an important fail-safe measure. Such laws provide districts with the ability to respond if a student has an asthma emergency at school but either lacks a diagnosis or does not have access to their own medication. As of September 2019, 13 states have enacted either a law or regulation authorizing the stocking of asthma rescue medication in schools: Arizona, Colorado, Georgia, Illinois, Missouri, New Hampshire, New Jersey, New Mexico, Oklahoma, Ohio, Texas, Utah, and West Virginia. Three additional states provide stock albuterol asthma guidelines but do not have legislation: Indiana, New York, and Nebraska. Some states have found that these policies reduce the need for 911 calls and emergency medical services transports as a result of asthma exacerbations. Initial data also demonstrate that these policies reach populations in need and improve health outcomes. This case study will describe the current state of asthma in Illinois, an innovative policy solution to address asthma emergencies in schools, and the steps taken to advocate for stock asthma rescue medication in Illinois. Legislation for stock albuterol in Illinois was signed into law in August 2018.

Stories of success: a qualitative examination of contributors to excellence in school drinking water access.

OBJECTIVE: Drinking water instead of beverages with added sugar can help prevent obesity and cavities and promote overall health. Children spend much of their day in school, where they have variable access to drinking water. In 2010, federal and state law required California public schools to provide free potable water to students in areas where meals are served and/or eaten. The current study aims to identify factors associated with an excellent drinking water culture in schools. DESIGN: A qualitative assessment of barriers and facilitators to providing excellent water quality and access in a purposive sample of California schools. In-depth interviews with key informants were conducted using a snowball sampling approach, after which data were analysed using both inductive and deductive methods. SETTING: California public elementary, middle/junior and high schools. PARTICIPANTS: Knowledgeable individuals involved in initiatives related to school drinking water accessibility, quality or education at each selected school. RESULTS: Thirty-four interviewees participated across fifteen schools. Six themes emerged as prominent facilitators to a school's success in providing excellent water access to students: active and engaged champions, school culture and policy, coordination between groups, community influences, available resources and environmentalism. CONCLUSIONS: While policy is an important step for achieving minimum standards, resources and interest in promoting excellence in drinking water access and quality can vary among schools. Ensuring that schools have dedicated staff committed to advancing student health and promoting the benefits of water programs that are more salient to schools could help reduce disparities in drinking water excellence across schools.

Association of State Laws Regarding Snacks in US Schools With Students' Consumption of Solid Fats and Added Sugars.

Importance: The Smart Snacks in School standards (hereafter, Smart Snacks) were issued in 2013 with the aim of improving students' dietary intake behaviors. Goals of Smart Snacks included reducing total energy intake, consumption of solid fats and added sugars, and sodium intake. Smart Snacks standards were required to be implemented by the start of the 2014 to 2015 school year at all US schools participating in federal child nutrition programs. Objective: To examine the association of state laws that specifically direct schools to implement Smart Snacks with student dietary consumption outcomes. Design, Setting, and Participants: This cross-sectional study used nationally representative data collected in the 2014 to 2015 school year as part of the School Nutrition and Meal Cost Study. Students in grades 1 through 12 (ages approximately 6-18 years) were randomly selected from 310 public schools in 30 US states and the District of Columbia. Analytic weights were applied and all percentages reported are weighted. Analyses were conducted from March 1, 2018, to December 12, 2019. Exposures: State laws requiring schools to implement Smart Snacks. Main Outcomes and Measures: A 24-hour recall was used to assess student dietary intake as daily kilocalories consumed as (a) total energy, (b) solid fats and added sugars combined, (c) solid fats, or (d) added sugars. Milligrams of daily sodium consumption were also computed. Results: Among 1959 students (mean [SD] age, 11.9 [3.5] years; 1014 [50.9%] boys), 420 students (22.5%) attended school in a state with Smart Snacks laws, and 528 students (26.1%) consumed snacks obtained at school. In covariate-adjusted models, total energy intake did not vary based on state law. Adjusted mean daily kilocalories from solid fats and added sugars was significantly lower among students in states with laws (508.7 [95% CI, 463.0 to 554.4] kcal) than among students in states without laws (562.5 [95% CI, 534.3 to 590.8] kcal; difference, -53.9 [95% CI, -104.5 to -3.2] kcal; P = .04). Consumption of sodium did not differ by state law. Kilocalories from solid fats contributed more to the difference than kilocalories from added sugars (-37.7 [95% CI -62.8 to -12.6] kcal vs -16.2 [95% CI, -51.3 to 19.0] kcal). Conclusions and Relevance: These findings suggest that students in states with laws requiring schools to implement Smart Snacks had better dietary intake than students in states without laws, consuming a mean of 53.9 fewer kilocalories from solid fats and added sugars per day, after adjusting for covariates. State-level policy mechanisms may support schools' implementation of federal standards in ways that are associated with healthier diets among children and adolescents.

Context and regulation of homeschooling: Issues, evidence, and assessment practices.

The article discusses salient factors that influence the current context within which homeschooling occurs. Individual states have applied various approaches to establish regulations that both preserve the rights of homeschooling parents and fulfill the state's obligation to ensure that its residents receive the education to which they are constitutionally entitled. Case and ethnographic studies or research involving small and selected samples often appear in outlets associated with homeschool advocacy groups or in outlets that are not mainstream. The paucity of empirical evidence derived from methodologically strong research paradigms has led to little certainty about many aspects of homeschooling, including its effectiveness in preparing an educated citizenry. From state to state, the understanding and definition of homeschooling vary widely, leading to equally wide variations in regulatory practices. The article documents and summarizes state-to-state variations in matters pertaining to homeschooling and offers recommendations to help school psychologists work more effectively with students who are educated at home.

Falling short: When testing is mandated and follow-up is not.

In 1999, the Texas Legislature mandated acanthosis nigricans (AN) screening in primary schools in designated regions of the state through the passage of House Bill 1860 to identify children at risk for diabetes by identifying the skin condition AN. AN is related to insulin resistance, and, thus, is associated with type 2 diabetes (diabetes mellitus type 2 [DMT2]), a growing concern among school-aged children. Since 1999, millions of children have been screened and hundreds of thousands have been screened positive. No data are available about the effectiveness of the program in identifying DMT2 among the school-aged population because no follow-up is mandated. The current practice is to send a letter to the parents of the child who screens positive, advising the parents to take the child to a health care provider for further assessment. Hence, children within the state may have diabetes or are developing diabetes but have yet to be diagnosed. In light of the presence of a law mandating AN screening, mandating a follow-up to identify those who have diabetes or are developing the condition of diabetes can provide early intervention and decrease costs of care. It is not known why the follow-up of those who screen positive was not included in the initial legislation. It may have been due to the cost of the necessary blood tests that are used to assess an individual for diabetes. Related to this is the reality that blood tests are invasive procedures, whereas screening for a skin disorder is not, thereby possibly explaining the omission of mandated follow-up from the legislation .

Understanding the impact of state vaccination laws on exemption rates.

PURPOSE OF REVIEW: This review summarizes the current state of school-entry vaccination requirements and related exemption policies in the United States and examines recent changes to these policies. RECENT FINDINGS: With recent infectious disease outbreaks in the United States, there has been heightened awareness on unvaccinated individuals, and the state-level policies that allow individuals to be exempted from school-entry vaccination requirements. Between 2015 and 2017, there have been eleven states that have altered their policies regarding school-entry vaccination requirements and related reporting for which no formal evaluations have been published. One policy change during that period, California SB 277, which became law in 2016, reduced the nonmedical exemption and increased the childhood vaccination coverage rate in that state, though with some evidence of exemption replacement through the use of medical exemptions. Through September 2019, five additional state law changes have been enacted. SUMMARY: The large number of heterogeneous changes to state-level policies for school-entry vaccination requirements in recent years need rigorous evaluation to identify best practices for balancing public health authority and parental autonomy while seeking to achieve the highest level of infectious disease prevention for children.

Laws About Transparent School Vaccination Reporting: Public Health Context and Ethics.

In response to a recent surge in vaccine exemptions for school-aged children, advocacy for transparency regarding school vaccination rates has gained momentum in the sphere of public policy and legislation. We explore the public health context for transparency-focused school vaccination reporting laws and recent legislative successes and failures. We then provide an ethical analysis of policy that mandates publicly accessible, granular reporting of school vaccination rates.The ethical justification for this type of policy is robust. Although there is no evidence demonstrating its effects on public health, transparent school vaccination reporting has the potential to enhance individual and public decision-making, especially concerning the protection of children with compromised immune systems. This policy also offers the benefit of preserving the autonomy of parents who choose not to vaccinate their children.Policymakers in all states should support passage of this type of legislation along with other effective vaccination policies, including evidence-based vaccine education for parents who seek exemptions and reimbursement for clinicians who provide vaccine-related counseling.

Sports Medicine Delivery Models: Legal Risks.

Educational institutions sponsoring competitive athletics may use an athletics model, academic model, or medical model for delivery of sports medicine to student-athletes. Four types of legal risk are considered for these 3 models: litigation, contract, regulatory, and structural. The athletics model presents the greatest legal risk to institutions, whereas the medical model presents the least legal risk. Institutional administrators should consider these risks when selecting or maintaining a delivery model for sports medicine.

Liability Determination of School Sports Injury Accidents: An Analysis Framework Based on Evolutionary Game.

In recent years, the outbreak of many school sports injury accidents aroused widespread public concern about liability determination of accident. Previous studies have examined the legal application of the liability principles from a law perspective, but few kinds of research attempted to analyze the progress of liability determination from the perspective of "law economics". To fill this research gap, we introduce the evolutionary game model, as an important theoretical tool of "law economics", to investigate how various factors influence the strategy selection of the parties, as well as examine what liability principle can effectively treat school sports injury accidents. The results indicate that the strategic selection of the subject of liability is significantly related to the accident compensation cost and the prevention cost of both parties. Moreover, we also find that both strict and proportional liability rules can play key roles in dealing with the issue of liability determination of school sports injury accidents, but the two liability rules have different effects on the strategic selection of parties. More specifically, compared to the strict liability principle, the proportional liability principle can motivate both the school and the students to adopt the active strategy of "appropriate caution" to prevent occurring sports injury accidents in schools.

High School Physical Activity and Nutrition Policy: Summarizing Changes Over Time Using Latent Class Analysis.

INTRODUCTION: High school physical activity and nutrition policies can substantially affect student behavior and outcomes. Although public health officials and legislators have advocated for policy improvements, the extent to which policies have changed at local levels is not well understood. This study identifies latent classes of physical activity and nutrition policy environments and explores changes in prevalence of these classes from 2000 to 2016. METHODS: Data from the School Health Policies and Practices Study, a repeated cross-sectional survey from the Centers for Disease Control and Prevention administered at the school district level in 2000, 2006, 2012, and 2016, were analyzed in 2018. Using latent class analysis, policy environment subgroups were identified, described, and then dichotomized based on satisfaction in meeting recommendations. Associations of latent classes with year and urbanicity were evaluated using logistic regression. RESULTS: Five latent classes were identified each for physical activity and nutrition policy environments, all with distinct characteristics. Physical activity policies improved from 2000 to 2006 (p<0.001) and then plateaued until 2016, whereas nutrition policies improved consistently from 2000 to 2016 (p<0.001, p=0.011, p<0.001). Though significant disparities between urban and rural school districts were found, these disparities narrowed during the studied years, particularly for physical activity policies. CONCLUSIONS: The estimated proportion of school districts with satisfactory physical activity and nutrition policy environments increased from 2000 to 2016, possibly because of legislative and policy advocacy efforts. However, many areas for improvement remain. Unsatisfactory latent classes that remained prevalent though 2016 may highlight policy domains that should be targeted by future interventions or subject to further research.
