RESUMEN
Introduction: This study aims to identify levels of anxiety, depression, body weight, and levels of physical activity, as well as to verify possible associations among these variables in Brazilian adolescents. It is a cross-sectional study with a convenience sample of 291 Brazilian adolescents aged 13 to 15 years old (13.75±0.80 years old). Methods: Researchers assessed students by filling out questionnaires of anxiety and depression symptoms, as well as the level of physical activity and checking anthropometric measures. Parametric and non-parametric statistics were used to compare groups divided by psychological, physical and overweight factors for boys and girls, adopting a significance level of 95%. Results: Results showed higher waist circumference and physical activity levels for boys (p<0.01) and higher scores for anxiety and depressive symptoms questionnaires for girls (p<0.01). In addition, a low prevalence of depression was observed in boys (0.69%/CI0.03-4.36). For anxiety and depression variables in males and females with and without overweight and physically active and inactive, there were significant differences between groups (p < 0.05), but not within groups. Conclusion: The identification of a higher prevalence of girls with anxiety and depression was observed in this study and reinforced this information already demonstrated in the scientific literature. In general, the prevalence of depression was low in boys, while the prevalence of overweight, sedentary lifestyle, anxiety and depression were higher in girls.
RESUMEN
Apesar de sua importância, a avaliação da aptidão cardiorrespiratória em idosos mostra-se difícil em virtude das condições clínicas e funcionais dessa população. Alternativas mais acessíveis que possibilitem essa avaliação sem a realização de exercícios seriam importantes. Muitas delas utilizam como instrumento para detectar o nível de atividade física a escala Physical Activity Rating (PA-R). O presente estudo teve como objetivo verificar a validade de critério da versão em português da PA-R e a sua equivalência com a versão original. Foram incluídos 98 idosos (43 mulheres) com idades entre 60 e 91 anos, atendidos pelo Núcleo de Atenção ao Idosos (NAI) da Universidade Aberta da Terceira Idade (UnATI-UERJ). Após o preenchimento da escala, os escores obtidos foram correlacionados com o valor de VO2pico medido durante teste de exercício cardiopulmonar máximo em cicloergômetro de membros inferiores. Os resultados encontrados (r=0,61 para amostra completa; 0,59 em homens; 0,70 em mulheres) sugeriram a validade da escala e foram similares aos obtidos pela versão original, o que indica a equivalência de mensuração da mesma. Recomenda-se com isso, a utilização da PA-R em indivíduos idosos. Contudo, é necessário o desenvolvimento de novos estudos com diferentes faixas etárias para que os achados possam ser generalizados.
Despite its importance, the cardiorespiratory fitness assessment in older adults is difficult due to the clinical and functional conditions of this population. More affordable alternatives that enable this evaluation without performing exercise testing would be important. Many of them include the Physical Activity Rating (PA-R) scale as a tool to detect the physical activity level. The present study aimed to verify the criterion-related validity of the Portuguese version of PA-R and its measurement equivalence to the original version. The sample was composed of 98 elderly (43 women), between the ages of 60 and 91 years, attended by the Elderly Care Center of the Open University of the Third Age (UNATI-UERJ). After completing the scale, the scores were correlated to the VO2peak assessed during a supervised maximal exercise test using an electromagnetically braked cycloergometer. The results found (r=0.61 to the whole sample; 0.59 to men; 0.70 to women) suggested the scale validity and they were very similar to those obtained by the original version which indicates the measurement equivalence. It is recommended the use of the PA-R in older adults. However, it is necessary the development of new studies in different ages to generalize the results.
