RESUMO
OBJECTIVE: To investigate the association between body image disorders and the lifestyle and body composition of female adolescents. DESIGN: Cross-sectional study. SETTING: The Body Shape Questionnaire (BSQ) and Silhouette Scale and Sociocultural Attitudes Towards Appearance Questionnaire-3 were used to evaluate the participants' body image. Body composition was evaluated by a Dual-Energy X-ray Absorptiometry equipment, and lifestyles were identified by latent class analysis (LCA) using the poLCA package for R. PARTICIPANTS: Female adolescents aged 14-19 years old, in the city of Viçosa-MG, Brazil. RESULTS: In total, 405 girls participated in the study. Almost half of the participants were dissatisfied with their current physical appearance (51·4 %), presented body perception distortions (52·9 %). 47·3 % of the adolescents were dissatisfied with their body according to the BSQ, and another 8 % severely so. Subjects with an 'Inactive and Sedentary' latent lifestyle were 1·71 times as likely to feel dissatisfied as those with active and sedentary or inactive and non-sedentary lifestyles (95 % CI 1·08, 2·90, P = 0·047). Body image disorders showed an association with decreased amounts of moderate and vigorous physical activity, high screen time, increased alcohol consumption and excess body fat. CONCLUSIONS: Particular patterns of lifestyle and body composition seem to be associated in female adolescents with dissatisfaction with, distortion of and excessive concern about appearance. Specifically, physical inactivity, sedentary behaviour, alcohol consumption and high body fat percentage may be strongly linked to body image disorders.

AIMS: Despite the fact that self-medication associated with temporomandibular disorders is clinically quite common and is considerably harmful, there is no instrument in the literature to assess this practice. The aim of this study was to construct and validate a questionnaire to study this important issue specifically. METHODS: After completing the literature review, semi-structured interviews, focus group and pretest, the first version of the instrument resulted in 62 questions. After face validity testing, pretest and the necessary corrections and changes, the instrument had 41 questions and was administered for validation to a sample of 110 patients diagnosed with TMD according to the RDC/TMD (1992) criteria. RESULTS: According to factor analysis, seven questions with loadings below 0.30 were removed, with the final version consisting of 34 questions. The analysis of internal consistency and temporal stability showed values of 0.844 for Cronbach's alpha coefficient and a Kappa coefficient of 0.810, respectively, indicating that the instrument presents sufficient reliability and reproducibility for its proposed objective. After validation, with the ultimate goal of classifying patients according to the degree/intensity of self-medication, a classification was proposed that allowed the discrimination of results into three distinct groups regarding self-medication exposure: mild, moderate or severe, based on the self-medication raw point score. CONCLUSION: The results of the instrument validation process showed that it has suitable properties for evaluating the practice of self-medication in patients with TMD.

The habits of birds make them more or less susceptible to parasitism by certain tick species. Therefore, while some bird species are typically found to be intensely infested, others are relatively unaffected. This study investigated the occurrence of ticks in Passeriformes inhabiting an Atlantic Forest fragment in southeastern Brazil, during the dry and rainy seasons, by means of parasitological indexes and multiple correspondence analysis, to determine the factors that influence tick parasitism in these birds. Data were collected on 2391 ticks, all classified in the Amblyomma genus, from 589 birds. The ticks identified to the species level were A. longirostre, A. nodosum, A. calcaratum, A. parkeri, and A. ovale. Thamnophilidae, Conopophagidae, Thraupidae, Dendrocolaptidae, and Platyrinchidae were the families with the highest prevalence. In terms of parasite intensity, the families Conopophagidae, Thamnophilidae, Thraupidae, Furnariidae, and Pipridae stood out with the highest values. Bird species that are generalists regarding eating habits and habitat occupation tended to have higher parasite loads, as did larger species and those inhabiting the understory. The tick prevalence was higher in the dry season than in the rainy season. The majority of the ticks were collected from the head region, mainly around the eyes and in the nape. Also, this work reports 22 new bird-parasite relations.
