This paper reviews studies using empirical, data-driven methodologies, such as cluster analysis and latent class analysis, to identify clustering patterns of diet, physical activity and sedentary behavior among children or adolescents and their associations with socio-demographic indicators, and overweight and obesity.

The clustering of diet, physical activity and sedentary behavior in children and adolescents: a review

Diseases caused by Xylella fastidiosa have attained great importance worldwide as the pathogen and its insect vectors have been disseminated. Since this is the first plant pathogenic bacterium for which a complete genome sequence was determined, much progress has been made in understanding the process by which it spreads within the xylem vessels of susceptible plants as well as the traits that contribute to its acquisition and transmission by sharpshooter vectors. Athough this pathogen shares many similarities with Xanthomonas species, such as its use of a small fatty acid signal molecule to coordinate virulence gene expression, the traits that it utilizes to cause disease and the manner in which they are regulated differ substantially from those of related plant pathogens. Its complex lifestyle as both a plant and insect colonist involves traits that are in conflict with these stages, thus apparently necessitating the use of a gene regulatory scheme that allows cells expressing different traits to co-occur in the plant.

Living in two worlds: the plant and insect lifestyles of Xylella fastidiosa.

The aim of this research was to analyze the individual and socioenvironmental perceived quality of life in the Physical Education teaching career in Public State Schools in the state of Rio Grande do Sul, according to the Professional Cycles of Development (CPD). This research used as instruments the Elementary and High School Physical Education Teachers Evaluation Scale of Life Quality at Work (QVT-PEF), and the Individual Lifestyle Profile. The sample selection process was proportionally stratified by geographical areas of the state of Rio Grande do Sul and randomly selected per conglomerate, including 380 Physical Education teachers (141 males and 239 females), with an age range of 23-60 years old (Average = 40,18; DP = 8,16). For the data analysis, the Chi-Square Test, the Kruskal Wallis Test and the Fischer's Exact Test were adopted, with a significance level of p < 0.05. The results showed that most teachers were satisfied with their quality of life at work (QVT), except in terms of income and compensation dimensions. The increase in quality of life at work satisfaction levels is associated with the progress in the teaching career, where teachers at tenior position presented the highest levels. Considering the demographic variables and CPD, the highest dissatisfaction levels in relation to wage and working conditions were observed among female teachers and post-graduated teachers in the consolidation and stabilization cycles; while the largest satisfaction levels were presented by married teachers in the diversification cycle and teachers of the consolidation cycle that work at one school only. With regards to the Individual Lifestyle Profile (PEVI), most teachers presented positive perception, especially the teachers in the entrance and consolidation cycles, who presented a more positive profile. The results did not confirm the existence of an association between the individual and socioenvironmental parameters of quality of life.

OBJECTIVE: To analyze the factors associated with the presence of depression symptoms in women after breast cancer. METHODS: Cross-sectional study with 181 women with breast cancer, aged 57.0 years (SD = 9.5), who were undergoing treatment or after treatment in the Oncology Research Center in Florianopolis, state of Santa Catarina, Brazil. The questionnaire comprised items addressing general and health information, economic level, anthropometric measures, depression symptoms (Beck Depression Inventory), self-esteem (Rosenberg Self-Esteem Scale), and body image (Body Image After Breast Cancer Questionnaire). Descriptive and inferential statistical analysis were performed by chi-square and Fisher's exact tests to verify association, Mann-Whitney U test to compare the groups and Poisson regression to identify the prevalence ratio of the factors associated with presence of depression symptoms (p < 0.05). RESULTS: We found an association between the presence of depression symptoms and the group of younger women (aged 40–60 years), those who had another disease besides cancer, those who had mastectomy surgery, those who suffered from lymphedema, and those who presented low–medium self-esteem. Less educated women presented more depressive symptoms, as did women with worse body image on the subscales of limitations, transparency, and arm concerns. CONCLUSIONS: Age, educational attainment, diagnosis of other diseases, type of surgery, lymphedema, self-esteem, and body image were factors associated with the presence of depression symptoms in Brazilian women after breast cancer. Health professionals should be aware of these relationships and try to detect depression symptoms earlier and improve the care they provide to these women.

The objective of this research was to verify the association between verbal bullying and untreated dental caries. The present cross-sectional study had a representative sample of 1,589 children, aged 8-10 years, from public schools. Information on verbal bullying related to the oral condition was obtained through a questionnaire directed to the students. Clinical data were collected by 4 calibrated examiners (kappa > 0.70) using the DMFT/dmft and PUFA/pufa indexes for caries. Socioeconomic issues were answered by those responsible. The prevalence of verbal bullying related to the oral condition was 27%. The results of the Poisson regression, in an adjusted multiple model, showed a significant association between bullying and untreated caries lesions (prevalence ratio, PR: 1.27; 95% CI: 1.07-1.52), PUFA/pufa index (PR: 1.34; 95% CI: 1.11-1.61), pulp involvement (PR: 1.35; 95% CI: 1.09-1.67), and abscess (PR: 1.74; 95% CI: 1.18-2.56). It was concluded that children with untreated dental caries had a higher prevalence of verbal bullying when compared to caries-free or disease-treated children.
