Background Common mental disorders (CMD) in children and adolescents can be initial and non-specific manifestations of more serious mental diseases and often persist into adulthood. Therefore, early detection is important, as is the identification of the factors that impact development. Insufficient sleep represents one of the most common and potentially remediable risks to mental health in children and adolescents for whom chronic sleep loss has become normal. This study aims to investigate the influence of sleep duration on CMD in schoolchildren and adolescents. Methods The data for this longitudinal study were derived from the community trial Parents, Students, Community Health Agents and Teachers for Healthy Eating (PAAPAS) in 2016 (N = 2743), with fifth and sixth graders from 18 public schools of Duque de Caxias, Rio de Janeiro, Brazil. CMD were assessed by the General Health Questionnaire (GHQ-12) at baseline and at a 9-month follow-up. Sleep duration was evaluated at baseline and was categorized as short, adequate or long according to age group. The effect of sleep duration on common mental disorders was analysed by sex using linear mixed-effects models. Results At baseline, the frequency of CMD was 33.2% and was higher in boys than in girls and higher among students with short sleep duration. There was an increase in the CMD score over time among girls with short sleep duration (p < 0.01). Among boys, a similar trajectory of the CMD score was observed in the subgroups with short and long sleep duration, but there was a significant reduction in the subgroup with long sleep duration (p = 0.05). Conclusion Changes in common mental disorder patterns differ according to sex, and short sleep duration seems to be problematic for students’ mental health. The promotion of health strategies that involve the family and school environment, such as later school hours, could help change this scenario.
Objective This study evaluated the influence of family meal frequency on the occurrence of common mental disorders (CMD) in children and adolescents over eight months of follow-up. Design Data from this longitudinal study were derived from the PAAPAS—Parents, Students, Community Health Agents, and Teachers for Healthy Eating—community trial. CMD were evaluated using the General Health Questionnaire. Frequency of family meals (breakfast and dinner) was categorized as “breakfast and dinner regularly with the family”, “at least breakfast or dinner regularly with the family”, and “does not have any meal regularly with the family.” The effect of family meal frequency on CMD was analyzed using generalized estimation equations with log-binomial models for repeated measures. Setting This study was conducted in public schools (N = 18) of Duque de Caxias, Rio de Janeiro, Brazil, in 2016. Participants Children (aged 9–11 years) and adolescents (aged 12–17 years) from the fifth and sixth grades (N = 2,743). Results These findings suggested that regular family meals were a protective factor for mental health. The adjusted relative risk of CMD was 0.75 (95% confidence interval = 0.69–0.83) for those who had two family meals regularly and 0.87 (95% confidence interval = 0.77–0.97) for those who had only one regular family meal, compared to students who had no regular family meals. Conclusions Potential strategies that educate and encourage families about the mental health benefits of eating regular meals together must be explored and implemented.
Este artigo visa avaliar a frequência de transtorno mental comum (TMC) entre os alunos de graduação de uma escola de formação militar, de acordo com características sociodemográficas e aspectos comportamentais. O estudo foi realizado em 2020, com 194 alunos entre 17 e 25 anos na Escola de Formação de Oficiais da Marinha Mercante (EFOMM) localizada no Rio de Janeiro. Para avaliar a presença de TMC foi usada a versão reduzida do General Health Questionnaire (GHQ-12). A análise dos dados apontou que os TMC estão presentes em 71.1% dos alunos participantes, sendo a maior frequência entre as jovens do sexo feminino, estudantes do segundo ano, mais velhos, entre os alunos não brancos (pardos, pretos e amarelos), baixa posição socioeconômica, não heterossexuais e os que sofrem maior influência da fé. Os resultados deste estudo podem auxiliar a identificar subgrupos mais vulneráveis, além da criação de medidas de prevenção e gestão mais focalizadas no ambiente universitário.
