Healthy dietary patterns linked to Brazilian adolescents' school meal adherence.

OBJECTIVE: This study aimed to verify the association between adherence to school meals provided by the National School Feeding Program and dietary patterns in adolescents from Brazilian public schools. METHODS: Data from the 2019 National School Health Survey were used, with a nationally representative sample of Brazilian school adolescents (n=53,477; 13-17 years old). Food consumption of healthy and unhealthy food markers was obtained from a food consumption questionnaire. Regular consumption was considered ≥5 times/week. Latent class analysis was used to identify dietary patterns whose association with adherence to school meals was evaluated by multinomial logistic regression models, with adjustment for sociodemographic and eating behavior variables. RESULTS: Three dietary patterns were identified: "unhealthy" - higher consumption of soft drinks and sweets (9.2% of adolescents); "healthy" - higher consumption of beans, vegetables, and fruits (27.1%); and "monotonous" - higher consumption of beans (63.7%). High adherence to school meals (every day) and unsatisfactory adherence (1-4 times/week) were positively associated with the healthy pattern even after adjustment for possible potential confounders (OR 1.37, 95%CI 1.23-1.52; OR 1.20, 95%CI 1.10-1.30, respectively). CONCLUSION: The results showed that the consumption of school meals offered by the National School Feeding Program can contribute to healthy eating habits among Brazilian adolescents.

Association between bullying at school and tooth loss among 15-19-year-olds from southern Brazil.

This study aimed to investigate the association between bullying at school and tooth loss in southern Brazilian adolescents. This population-based cross-sectional study included a representative sample of 15-19-year-old students attending high schools in Santa Maria, southern Brazil. Data on sociodemographic and behavioral variables were collected through questionnaires. Contextual data on bullying at school was provided by educational institutions (bullying episodes in the previous year: 'no,' 'sometimes,' or 'often'). Tooth loss was clinically assessed by the M component of the DMFT index, modeled as a discrete variable. Multilevel Poisson regression was used, and rate ratios (RR) and 95% confidence intervals (CI) were estimated. The prevalence of tooth loss was 9.2% (95%CI = 7.5-10.8). Adolescents who attended the schools where bullying events often occurred had 0.39 (95%CI = 0.33-0.45) missing teeth, on average, in contrast to an average of 0.14 (95%CI = 0.08-0.19) among those whose schools did not experience bullying in the previous year. After adjusting for important cofactors, the contextual variable of bullying at school remained significantly associated with the study outcome. Adolescents who attended schools where bullying frequently occurred were 2.49-fold more likely to have an additional missing tooth than those whose school did not experience bullying in the previous year (RR = 2.49, 95%CI = 1.37-4.51, p = 0.003). In conclusion, the frequent bullying episodes at school were associated with more permanent teeth lost due to caries in this population. Hence, improving the school environment may improve the oral health of adolescents.

Water, Sanitation, and Hygiene Infrastructure and Resources in Schools in Belize during the COVID-19 Pandemic, 2021-2023.

Access to water, sanitation, and hygiene (WASH) resources in schools is critical for disease prevention and control, especially during public health emergencies. In Belize, systematic, national data on WASH in schools are needed to inform public health decisions and interventions. From December 2021 to January 2022, a national survey was sent electronically to government and government-aided primary and secondary schools in Belize (N = 308) to gather information on WASH services. From the survey, 12 pilot schools were selected based on the highest self-reported need for WASH resources to participate in additional evaluation and intervention, which included environmental nudges, supplemental supply provision, and hand hygiene education. To understand how the progression of the COVID-19 pandemic may have influenced hand hygiene, facility assessments to evaluate access to hand hygiene resources were conducted in person when most schools reopened for face-to-face learning during the pandemic (March 2022) and 15 months later (June 2023). Among the schools participating in the national survey (N = 221), 55% reported times when water was not available at the schools. Almost 9 in 10 schools (89%) had a functional handwashing station, and 47% reported always having soap for handwashing. Between baseline and follow-up at the 12 pilot schools, we observed decreases in the proportion of functional handwashing access points (-11%), functional handwashing access points accessible for individuals with disabilities (-17%) and small children (-29%), and functional alcohol-based hand rub dispensers (-13%). Despite the ongoing COVID-19 pandemic, we observed gaps in WASH resources in schools in Belize during the onsite assessments at the pilot schools. Schools should be encouraged and provided with WASH resources to maintain vigilance for disease control measures.

Analysis of the association between high workload and musculoskeletal pain in public school teachers according to physical activity level.

BACKGROUND: A high workload has been associated with musculoskeletal pain in public school teachers. However, the hypothesis of the present study was that physical activity (PA) practice is able to attenuate this association. OBJECTIVE: To analyze the associations between high workload with musculoskeletal pain according to PA levels in public school teachers. METHODS: Teachers (n = 239) from 13 public schools were evaluated. Workload was assessed using a Likert scale in which teachers reported their perception of their work routine as: very low, low, regular, high, and very high. Musculoskeletal pain and PA were assessed using questionnaires. Multivariate logistic regression models were used to investigate the association of high workload with PA levels and musculoskeletal pain in different body regions, compared to participants with normal workload, adjusted by sex, age, and socioeconomic status. RESULTS: A high workload was associated with higher chances of reporting pain in the wrists and hands (OR = 3.55; 95% CI = 1.27-9.89), knee (OR = 3.09; 95CI%  = 1.09-8.82), and feet and ankles (OR = 3.16; 95% CI = 1.03-9.76) in less active teachers. However, these associations were not observed in teachers considered more active. CONCLUSION: PA practice is able to act as a good protector against musculoskeletal pain in teachers, even in individuals with a high workload.

Physical activity of adolescents and the urban environment of Brazilian capitals: National School Health Survey, 2015.

This study aimed to evaluate the practice of physical activity (PA) among adolescents and its association with characteristics of the urban environment of Brazilian capitals. Study with adolescents from the 26 Brazilian capitals and the Federal District participating in the National School Health Survey, 2015 edition. The association between regular practice of PA (≥300 minutes/week) and the dimensions of urban well-being (urban mobility, urban environmental conditions, urban housing conditions, urban collective services, and urban infrastructure) was examined using multilevel logistic regression. A total of 50,904 adolescents were evaluated, among which 20.7% were active. It was observed in the multiple model that adolescents who live in capitals with better urban environmental conditions, such as the presence of tree coverage, less open sewage, and less accumulated garbage around the houses, are more likely to be active (OR = 1.06; 95% CI:1.01;1.12). Adolescents who live in cities with less urban disorder are more likely to be active.

Attention-deficit/hyperactivity disorder in Mozambique: an epidemiological investigation in a primary school sample.

OBJECTIVE: To evaluate the prevalence of attention-deficit/hyperactivity disorder (ADHD), comorbidity rates with disruptive behavior disorders and main negative outcomes in primary school students in Nampula, Mozambique. METHODS: We selected a random sample of 748 students for ADHD screening from a population of around 43,000 primary school students. The Swanson, Nolan, and Pelham Rating Scale version IV was applied to both parents and teachers. All students who screened positive (n=76) and a propensity score-matched random subset of students who screened negative (n=76) were assessed by a child psychiatrist. RESULTS: The prevalence of ADHD was estimated at 13.4% (95%CI 11.5-19.2), and 30.6% of those with ADHD presented comorbid disruptive behavior disorders. Students with ADHD (n=36) had significantly higher rates of both substance use (alcohol, marijuana) (p < 0.001), and school failures than controls (n=96; p < 0.001). Comorbidity between ADHD and disruptive behavior disorders increased the chance of substance use (p < 0.001). Secondary analyses with more restrictive ADHD diagnostic criteria revealed a lower prevalence rate (6.7%; 95%CI 5.2-12.9) with similar patterns of associated factors and negative outcomes. CONCLUSION: Our findings demonstrated that ADHD is a prevalent mental disorder in Mozambique, and it is associated with similar comorbid profiles, predisposing factors, and negative outcomes, as in other cultures.

Effects of homicide timing on test scores: Quasi-experimental evidence from two cities in Colombia.

This study examines the effect of homicides around schools on the standardized test scores of fifth and ninth graders (N = 4729; Mage = 12.71 years, SDage = 2.13) using a quasi-experimental design in two Colombian cities. Exposure to homicides occurring within 7 days of the test and within 500 m of the school decreases test scores by 0.10 SD. Effects show a greater sensitivity to timing than distance, becoming null as the time to the testing date increases but remaining consistent across larger radii. Since students in the study are on average exposed to 12.1 homicides per year, even short-lived learning losses can accumulate to impair learning for substantial portions of the school year. Findings are discussed, considering previous empirical work.

Tracking of physical activity and sedentary behavior of adolescents in different domains

This study aimed to verify the tracking of physical activity and sedentary behavior in different domains during adolescence. This longitudinal study involved 265 subjects (boys: 52.8%) with an initial mean age of 13.9 (± 1.2) years. Physical activity and sedentary behavior were verified using a questionnaire. The achievement of ≥ 150 min. week-1of moderate-to-vigorous intensity sport and/or physical exercise for ≥ 1 month was adoptedas sufficiently active. The data were collected on 2 occasions, with an average interval of 3 years. The description of the results used the relative frequency and Binary Logistic Regression was used to estimate the crude and adjusted odds ratios (95% confidence intervals). Current physical activity (adjusted odds ratios = 3.05; 95% confidence intervals: 1.77 -5.26) and sedentary behavior (adjusted odds ratios = 1.81; 95% confidence intervals: 1.03 -3.19) appear to be significantly influenced by previousbehavior, except for light-intensity physical activity. Only 12.8% of the participants remained sufficiently active for sport and/or physical exercise. Practice for at least one month of sport and/or physical exercise at baseline was a predictor of practice in the follow-up, both considering participation for at least one month (adjusted odds ratios = 2.81; 95% confidence intervals: 1.37 -5.79) and for four months (adjusted odds ratios = 2.47; 95% confidence intervals: 1.17 -5.24) in the follow-up. Beingsufficiently active at baseline increased the chance of being sufficiently active in the follow-up during adolescence. Interventions providing sufficient sport and/or physical exercise could positively influence the chances of practice in the future. For light-intensity physical activity interventions, strategies targeting adherence seem especially relevant.

Athletic Trainer-Reported Prevalence of Mental Health, Substance Use, and Barriers to Health in Secondary Schools.

CONTEXT: Where a person lives can have a significant effect on health. Limited access to health care, food insecurity, lack of affordable housing, and violence increase a person's likelihood of poor health. Athletic trainers (ATs) can contribute to identifying and improving the determinants of health that affect student-athletes. OBJECTIVES: (1) What were the current perceptions ATs had about the health behaviors (specifically mental health and substance use) of high school student-athletes? (2) What were the barriers that ATs experienced when providing health services to high school student-athletes? (3) How did the developed environment affect the health behaviors and barriers that ATs observed? DESIGN: Qualitative study. SETTING: Online survey. PATIENTS OR OTHER PARTICIPANTS: Certified National Athletic Trainers' Association members employed in the secondary school setting. MAIN OUTCOME MEASURE(S): Demographics of ATs were collected, and the ATs' perceptions of the health of student-athletes across developed environments, prevalence of mental health issues, tobacco and substance use, barriers to health care services, and housing and food insecurities among student-athletes were surveyed. Descriptive statistics for the outcome measures were reported. RESULTS: A total of 7600 electronic surveys were distributed to the ATs and 911 responded (females = 62%, average age = 36 years, average experience = 12.5 years). The school setting was identified by 82.5% as public and the environment as suburban by 43.7%, rural by 30.1%, and urban by 26.1%. Participants perceived a high average prevalence of mental health concerns (32%), e-cigarette use (31.7%), and marijuana use (26.9%) among student-athletes. Significant perceived barriers to health included limited access to transportation, poverty, and housing and food insecurities. CONCLUSIONS: This study highlights the health disparities and barriers ATs observed when addressing the health care needs of student-athletes. Understanding the determinants of health in order to identify the causes of health disparities may better prepare ATs to manage the health needs of underserved student-athletes.

How the COVID-19 contingency affects children.

Background: Due to the pandemic, children are undergoing many changes in their daily lives. Methods: We analyzed how parents perceive the effects of the contingency on their children through an online survey shared by digital media for 7 days. Results: We obtained 4000 responses. The most frequent difficulty of the children was online homeschooling (30.4%), followed by sleeping disorders (20.3%). The use of screens increased 30-80% in over 65% of children. Tantrum was detected in 34% and mood swings in 30% of children. The majority of parents (77.8%) considered that distance education does not guarantee children's education and that the level of learning acquired through online classes is not the same as that of face-to-face education (83.5%). In contrast, 70.6% of parents considered that it is not yet time to reopen schools, 78.8% believed that there is sufficient evidence to keep them closed, and 45% indicated that it is better not to return to campus this year. Regarding activities to improve mental health during the contingency, 51.3% have created home games, and 23.6% perform physical activity. However, 74.4% do not have the peace of mind to restart daily life. Among the positive aspects of the contingency, adaptability (35%) and family union (33.5%) were reported. Conclusions: Health professionals in contact with children must be prepared for the problems that this contingency is generating and sensitize parents to observe their children and seek professional help on any alarm data on the emotional or behavioral state of the child.

Introducción: Debido a la pandemia, la población infantil ha experimentado cambios en varios aspectos de su vida cotidiana. Métodos: Se analizó la percepción de los padres con respecto a los efectos de la contingencia en sus hijos a través de una encuesta en línea compartida por medios digitales durante 7 días. Resultados: Se obtuvieron 4000 respuestas. La dificultad más frecuente a la que se enfrentan los niños en la pandemia son las clases en línea en casa (30.4%), seguida de problemas para dormir (20.3%). Se identificó un incremento en el uso de pantallas del 30-80% en más del 65% de los niños. Se detectaron berrinches en el 34% y cambios de humor en el 30% de los niños. La mayoría de los padres (77.8%) consideraron que la educación a distancia no garantiza la educación de los niños, y que el nivel de aprendizaje de las clases en línea no es igual que el de las clases presenciales (83.5%). Por otro lado, el 70.6% de los padres opinaron que no es momento para abrir los colegios, el 78.8% indicaron que existe evidencia para mantenerlos cerrados y el 45% consideraron que es mejor no regresar este año al plantel. En cuanto a actividades para mejorar la salud mental en la contingencia, el 51.3% han creado juegos en casa y el 23.6% realizan actividad física. Sin embargo, el 74.4% no tienen tranquilidad para reiniciar su vida cotidiana. Dentro de las cosas positivas de la contingencia, se reportó adaptabilidad (35%) y unión familiar (33.5%). Conclusiones: Los profesionales de la salud en contacto con niños deben estar preparados para los problemas generados por esta contingencia y sensibilizar a los padres para observar a sus hijos y solicitar ayuda si detectan datos de alarma del estado emocional o conductual del niño.

Success of community approach to HPV vaccination in school-based and non-school-based settings in Haiti.

OBJECTIVES: To assess the success of a human papillomavirus (HPV) vaccination program among adolescent girls aged 9-14 years in Haiti and to understand predictors of completion of a two-dose HPV vaccination series. METHODS: Data collection was conducted during HPV vaccination campaigns in Port-au-Prince between August 2016 and April 2017. Descriptive statistics and logistic regression models were used to examine characteristics associated with vaccination series completion of school based and non-school based vaccination delivery modalities. RESULTS: Of the 2,445 adolescent girls who participated in the awareness program, 1,994 participants (1,307 in non-school program, 687 in school program) received the first dose of the vaccine; 1,199 (92%) in the non-school program and 673 (98%) in the school program also received the second dose. Menarche (OR: 1.87; 95% CI, 1.11-3.14), if the participant was a prior patient at the GHESKIO clinics (OR: 2.17; 95% CI, 1.32-3.58), and participating in the school-based program (OR: 4.17; 95% CI, 2.14-8.12) were significantly associated with vaccination completion. CONCLUSIONS: Vaccination in school- and non-school-based settings was successful, suggesting that a nationwide HPV vaccination campaign using either approach would be successful using either approach.

Low In-School COVID-19 Transmission and Asymptomatic Infection Despite High Community Prevalence.

There is concern that in-person schooling during the coronavirus disease 2019 (COVID-19) pandemic will facilitate disease transmission. Through asymptomatic surveillance and contact tracing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we found low rates of asymptomatic SARS-CoV-2 infection and little in-school transmission of COVID-19 when physical distancing and masking strategies were enforced despite a high community prevalence of COVID-19.

Cambios en sobrepeso y obesidad en escolares mexicanos de primarias públicas entre 2015 y 2018.

Objetivo. Cuantificar los cambios de sobrepeso y obesidad (SO+O) y determinar su asociación con características sociodemográficas en escolares mexicanos de primarias públicas durante 2015 y 2018. Material y métodos. Estudio transversal comparativo. Se analizaron 6.5 millones de alumnos de 59 724 escuelas. La información deriva del Registro Nacional de Peso y Talla (RNPT) en cuatro periodos escolares, de 2015 a 2019, para niños de 6 a 12 años. Se estimaron razones de momios (RM) y prevalencias ajustadas mediante regresión logística ordinal generalizada. Resultados. Las RM fueron positivas para SO+O y para obesidad en el sexo masculino, ámbito urbano y baja marginación (p<0.001). La mayor prevalencia ajustada tanto para sobrepeso como para obesidad se reportó en 2016 (p<0.001). La región Sur manifestó ascensos constantes y significativos para obesidad durante cuatro periodos. Conclusión. El RNPT permite detectar diversas características de riesgo actual para el desarrollo de SO+O en escuelas primarias del país.

Assessing the educational performance of different Brazilian school cycles using data science methods.

Educational indicators are metrics that assist in assessing the quality of the educational system. They are often associated with economic and social factors suggested to contribute to good school performance, however there is no consensus on the impact of these factors. The main objective of this work was to evaluate the factors related to school performance. Using a data set composed by Brazilian schools' performance (IDEB), socioeconomic and school structure variables, we generated different models. The non-linear model predicted the best performance, measured by the error and determination coefficient metrics. The heterogeneity of the importance of the variable between school cycles and regions of the country was detected, this effect may contribute to the development of public educational policies.

Keeping children healthy during and after COVID-19 pandemic: meeting youth physical activity needs.

BACKGROUND: The purpose of this study was to: 1) examine the maintenance of Physical Education and physical activity during the distance learning time, 2) determine the resources educators are utilizing to deliver PE curricula, and 3) understand the challenges experienced by educators during distance learning. METHODS: A survey was sent to a cohort of school-based fitness assessment software users. Respondents were largely school-based individuals including PE teachers (n = 1789), school (n = 62) and district administrators (n = 64), nurses (n = 3), and "other" (n = 522). RESULTS: Of 2440 respondents, most were from a city or suburb (69.7%), elementary or middle school (72.3%), and had Title 1 status (60.4%), an indicator of low socioeconomic status. Most campuses were closed during the COVID-19 pandemic (97.8%). Of the schools closed during the pandemic, only 2.8% had no prior PE requirements and that increased to 21% during the pandemic. In schools that remained open during the pandemic, 7.7% had no prior PE requirements and this increased to 60.5%. Importantly, 79% of respondents reported that students were either "significantly less" or "somewhat less" physically active during the closure. For closed schools, the most frequently cited challenges included "student access to online learning", "teacher/student communication" and "teacher remote work arrangements". For open schools, the most commonly reported challenges included "social distancing", "access to gymnasium/equipment", and "concern for personal health and wellbeing". CONCLUSION: The COVID-19 pandemic has caused important reductions in PE requirements and time engaged in physical activity. Challenges experienced by teachers were identified for closed and open schools.

School Type, Eating Habits, and Screen Time are Associated With Ultra-Processed Food Consumption Among Brazilian Adolescents.

BACKGROUND: The increasing consumption of ultra-processed foods (UPFs) may be a result of the environmental influences to which adolescents are exposed and/or habits acquired since childhood through family interactions. OBJECTIVE: Our aim was to investigate whether type of school administration (public or private), eating habits, and screen time are associated with the percentage caloric contribution of UPFs to total kilocalories consumed by Brazilian adolescents. DESIGN: A cross-sectional secondary analysis of the Study of Cardiovascular Risk in Adolescents (ERICA) performed between March 2013 and December 2014. PARTICIPANTS/SETTING: Overall, 71,553 adolescents from 1,247 public and private schools in 124 Brazilian cities (with a population of more than 100,000) were included. MAIN OUTCOME MEASURES: We measured the percentage caloric contribution of UPFs to the total kilocalories consumed, obtained using one 24-hour food recall. STATISTICAL ANALYSES PERFORMED: Generalized linear models were used, guided by the hierarchical model. Sample complexity was considered using the Stata svy command, with a significance level of 5%. RESULTS: Overall, UPFs contributed an average of 28% (95% CI, 27.80%-28.15%) of total energy intake. Based on the final multivariate analysis, a significantly higher UPF diet was observed among adolescents from private schools (P < .001), those who do not consume meals offered by schools (P < .001), those who do not eat breakfast regularly (P < .05), those who eat in front of screens almost every day or every day (P < .001), and those who spend more time in front of screens (P < .001). CONCLUSIONS: The findings of this study indicate that UPF consumption is associated with school type, eating habits, and screen time among Brazilian adolescents.
