Objective: to present the perception and knowledge of Brazilian nursing nurses and academics regarding Nursing Care Systematization. Method: a descriptive study, carried out in the first half of 2018. Results: of the 596 respondents, 86% perceived Nursing Care Systematization as very important, but only 60.9% used it in their care practice. Its use was statistically associated with a higher level of training. Non-utilization was associated with the perception that it is irrelevant and with little knowledge on the Nursing Process, even in the face of recognition of its obligation. Among professionals who wish to learn more about the subject, understanding the application of the process, especially the planning step, is perceived as a necessity. Conclusion: the relevance perception of systematization and levels of knowledge of the professional/academic are directly related to the use or not of Nursing Care Systematization principles.

O objetivo da pesquisa foi conhecer os hábitos cotidianos, relacionados à prática de atividade física, em 307 estudantes entre 12 e 17 anos, de seis escolas privadas, de Fortaleza - Brasil, entre os meses de março e junho de 2007. Foi aplicado um formulário para registrar sedentarismo, IMC, pressão arterial e glicemia. Para análise das proporções foi utilizado o teste do Qui-quadrado. Cerca de 68% dos jovens eram inativos. O sedentarismo foi maior nos pesquisados do sexo feminino (p=0, 000) e naqueles com excesso de peso (p=0,001). Entre os adolescentes ativos o exercício físico mais praticado era o futebol (42%) e a musculação (19%). A educação em saúde nas escolas pode auxiliar no combate desse sedentarismo juvenil.

This study clinically validated the nursing diagnosis of "sedentary lifestyle" (SL) among 564 Brazilian adolescents. Measures of diagnostic accuracy were calculated for defining characteristics, and Mantel-Haenszel analysis was used to identify related factors. The measures of diagnostic accuracy showed that the following defining characteristics were statistically significant: "average daily physical activity less than recommended for gender and age," "preference for activity low in physical activity," "nonengagement in leisure time physical activities," and "diminished respiratory capacity." An SL showed statistically significant associations with the following related factors: insufficient motivation for physical activity; insufficient interest in physical activity; insufficient resources for physical activity; insufficient social support for physical activity; attitudes, beliefs, and health habits that hinder physical activity; and insufficient confidence for practicing physical exercises. The study highlighted the four defining characteristics and six related factors for making decisions related to SL among adolescents.
