Impact of an Interdisciplinary Food, Nutrition and Health Education Program for adolescent Brazilian volleyball players

ABSTRACT Objective: To evaluate the impact of an Interdisciplinary Food, Nutrition and Health Education Program on nutrition knowledge, intention to change eating behavior, and body dissatisfaction of adolescent volleyball players. Methods: The sample consisted of 10 female volleyball players from the juvenile category of the city of Santos, São Paulo, Brazil, who participated in a program with eight monthly meetings (one discussion group followed by six educational activities and one final discussion group for evaluation). Results: Nutrition knowledge, body perception, intention to change eating behavior, eating attitudes and practices were investigated using questionnaires and discussion groups before and after the athletes' participation in ludic activities designed to address nutrition strategies for athletic performance and healthy eating, and how to deal with pressure for results and self-image. Nutrition knowledge improved from 57.0%±9.9 to 63.0%±11.8 (p=0.03) of correct answers. The mean body distortion score did not change (70.0±14.9 versus 76.5±22.4, p=0.235). Six athletes advanced in their intention to change eating behavior. Positive food practices were reported during the program and the identified discourses indicated the intention of changing the daily eating habits in the future. Conclusion: The program had a positive impact on nutrition knowledge and intention of changing eating behavior; however, for other issues, especially involving emotional aspects, further interventions should be planned

Elite squash players nutrition knowledge and influencing factors

Background There is a reported mismatch between macronutrient consumption and contemporary macronutrient guidelines in elite standard squash players. Suboptimal dietary practices could be due to a lack of nutrition knowledge among players. Subsequently, the purpose of this study was to assess the sports nutrition knowledge of elite squash players through the Nutrition for Sport Knowledge Questionnaire (NSKQ) and provide an indication of whether players require nutrition support to increase their nutrition knowledge. Methods This cross-sectional study assessed the nutrition knowledge of 77 elite squash players via the NSKQ over the period of June 2020 to August 2020. Results Players conveyed average nutrition knowledge with a mean NSKQ score of 48.78 ± 10.06 (56.07% ± 11.56%). There were no significant differences in NSKQ score between male and female players (p = .532). There was found to be a weak positive association between world ranking and NSKQ score (r = .208) and age and NSKQ score (r = .281). Players who had a relevant undergraduate degree (e.g. BSc Sport & Exercise Science) had significantly greater NSKQ score than players with no relevant qualifications (p = .022). Players who consulted a sports nutritionist to obtain their main source of nutrition information were shown to have significantly greater knowledge than those who acquired knowledge from a sports scientist (p = .01) or the internet / social media (p = .007). Conclusions Players should consult with a sports nutritionist to increase their sport nutrition knowledge. Future research should quantify the effectiveness of a nutritional education intervention at increasing nutrition knowledge in players

Fatores associados ao consumo da alimentação escolar por adolescentes no Brasil: resultados da PeNSE 2012

The aim was to study the association between socio-demographic and routine dietary variables and consumption of school meals by adolescents enrolled in public schools in Brazil. The study used data used from the National School Health Survey (PeNSE) 2012. To assess differences between schoolchildren based on whether or not they ate school meals, the study used Pearson's chisquare test, and associations were analyzed with univariate and multivariate Poisson regression models. Of the 86,660 students included in the study, 22.8% eat school meals. Higher consumption of school meals is associated with male gender, brown skin color, residence outside state capitals, working, and low maternal schooling, for those that ate breakfast and lunch with their parents. The findings are relevant for planning strategies to encourage consumption of school meals.Objetivou-se estudar a associação de variáveis sociodemográficas e de rotina alimentar de adolescentes com o consumo da alimentação escolar em escolas públicas brasileiras. Foram utilizados os dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) realizada em 2012. Para avaliar a diferença entre os escolares que consomem e não consomem a refeição na escola, foi realizado o teste de qui-quadrado de Pearson e as análises de associação foram realizadas por modelos de regressão de Poisson univariados e múltiplos. Dos 86.660 participantes do estudo, 22,8% consomem alimentação escolar. O consumo da alimentação escolar é maior entre os alunos do sexo masculino, pardos, que não moram em capitais, trabalham, com mães com baixa escolaridade, para aqueles que tomam café da manhã e almoçam com os pais. Esses achados são relevantes para planejar estratégias que incentivem o consumo da alimentação escolar.Univ Fed Sao Paulo, Rua Silva Jardim 136, BR-11015020 Santos, SP, BrazilUniv Estado Rio de Janeiro, Rio De Janeiro, BrazilUniversidade Federal de São Paulo, Rua Silva Jardim 136, BR-11015020 Santos, SP, BrazilWeb of Scienc
