Objective: To assess body image dissatisfaction among adolescents from Northern Minas Gerais. Method: This is a cross-sectional study with adolescents of both sexes, enrolled in the sixth to ninth year in the municipal public education network. A questionnaire was used, composed of sociodemographic and body image variables, which was obtained through a scale of silhouette figures. The anthropometric measurements of weight and height were performed to estimate body mass index. The correlation between the classification of the body mass index and the body image of adolescents was estimated through weighted Kappa. Results: A total of 535 adolescents participated, and 24.5% had different classifications between the real and ideal body image. The Kappa index for the classification of body image was 0.51, 0.58 and 0.32 for the total of adolescents, girls and boys, respectively. Conclusion: Public school adolescents are dissatisfied with their self-body image.

Resumo Investigou-se a associação entre o consumo de álcool pelos escolares com os conflitos familiares, supervisão dos pais e qualidade dos relacionamentos. Estudo transversal realizado com 1.265 adolescentes de 21 escolas. Foi utilizada a versão brasileira do Inventário de Triagem do Uso de Drogas/DUSI e estimadas prevalências absolutas e relativas para variáveis categóricas, e conduzidas análises bivariadas: teste Qui Quadrado de Pearson. Para magnitude da associação entre a variável dependente e independentes foram estimadas razões de prevalências por meio deregressão multivariável de Poisson. Houve associação do consumo de álcool com uso de drogas por familiares, discussões frequentes e desconhecimento dos pais sobre o que os adolescentes fazem. Supervisão familiar, bom relacionamento com pais/responsáveis, estabelecimento de vínculo familiar afetivo e ciência dos pais acerca do que os adolescentes fazem e onde estão, foram fatores de proteção para uso de álcool. Concluiu-se que a alta taxa de escolares que consomem álcool é preocupante, passível de complicações da saúde na sua integralidade, sendo fundamental relação familiar harmonizada. A implementação de práticas interventivas entre escola e Estratégia de Saúde da Família, podem contribuir no estabelecimento de vínculo protetivo.

Objective This study’s main objective was to investigate the emergence of back pain as a consequence to changes in usual activities due to the COVID-19 pandemic among teachers in public schools in the state of Minas Gerais, Brazil. Methods A cross-sectional study was conducted among 15,276 schoolteachers using an online questionnaire. The variables included sociodemographic and occupational data, health situation, habits and behaviors during the COVID-19 pandemic. Bivariate analyses using Pearson’s chi-square test and multiple analyses using Poisson regression were performed to identify the associated factors. Results About 58% of schoolteachers reported back pain due to changes in routine activities during the pandemic. The adjusted model showed a correlation between back pain and female sex, longer working hours, overwork, difficulties concerning distance working, negative changes in health status and quality of sleep; frequent feeling of sadness, depression, or anxiety; use of medications to relax, sleep or against stress/anxiety/depression; physical inactivity or negative changes in the practice of physical activities; increased body weight; reduction of leisure time; increased time of use of computer or tablet and overload of housework. Conclusion During the COVID-19 pandemic, schoolteachers reported a high prevalence of emergence of back pain, which delineates a contradiction in terms: on the one hand, distance education allows social distancing that contributes to the preservation of teachers’ health by reducing the risk of contamination by COVID-19. On the other hand, it imposes new demands that—in disagreement with working conditions—can threaten the health of these workers.

Resumo Objetivou-se investigar a relação entre Hipertensão Arterial (HA) e perfil ocupacional de docentes da educação básica pública e apresentar modelo teórico. Adotou-se amostra probabilística por conglomerados. A HA foi a variável dependente. As variáveis independentes foram agrupadas em blocos temáticos (Características Sociodemográficas, Perfil Ocupacional, Comportamentos e Desfechos em Saúde), que compuseram o modelo teórico. As análises foram corrigidas pelo desenho amostral. Foi conduzida regressão logística hierarquizada. A prevalência de HA foi de 25%, enquanto que 58% apresentaram insatisfação com o trabalho. Houve maior chance de HA entre os docentes mais velhos (OR = 3,7), sem pós-graduação (OR = 1,4), que atuavam também na rede privada (OR = 2,6), que apresentavam maior consumo de sal (OR = 1,7), com sobrepeso (OR = 2,1) / obesidade (OR = 7,2), com relação cintura-quadril elevada (OR = 1,9) e com hipercolesterolemia/hipertrigliceridemia (OR = 1,5) e menor chance entre os do sexo feminino (OR = 0,5), que exerciam outra atividade de trabalho (OR = 0,6) e insatisfeitos com o trabalho (OR = 0,6). Assim, o perfil ocupacional docente apresentou influência sobre a HA. A relação trabalho e saúde docente carece de atenção e cuidado, com adoção de medidas que preservem e promovam sua saúde e seu bem-estar.

The purpose of this study was to assess the LEPR gene Gln223Arg polymorphism (rs1137101) in oral squamous cell carcinoma (OSCC) and in potentially malignant oral lesions (PMOL) in comparison to normal oral mucosa in a Brazilian population. Smokers (n = 89) were selected from a representative sample of 471 individuals from the general population of Montes Claros, Brazil. Participants were age and gender matched to patients with OSCC (n = 25) and oral epithelial dysplasia (n = 25). We investigated the LEPR Gln223Arg polymorphism (A>G; rs1137101) in these groups. Genotype variants were assessed by RFLP-PCR, using MspI (HPAII) restriction endonuclease. The institutional review board of the Universidade Estadual de Montes Claros approved the study (process number 2667/2011). Written informed consent for this study was obtained from all participants. The GG genotype (Arg223Arg) appears to be the more relevant polymorphic variant in OSCC. It occurred, approximately, twice as frequently in OSCC patients than in the general population. In contrast, the A allele in its homozygosis form (Gln223Gln) is significantly associated with the development of PMOL; 80% of the samples from the PMOL group exhibit AA genotype. Our findings suggest new insights regarding LEPR gene variations in the development of OSCC and PMOL.
