Variação sazonal das atividades físicas e sedentárias de estudantes no semiárido baiano / Seasonal variation of physical activities and sedentary behaviors among schoolchildren

Este estudo analisou a variação sazonal das atividades físicas e dos comportamentos sedentários de uma amostra por conveniência de crianças e adolescentes, de uma escola pública no semiárido baiano (n = 462; 52,9% de meninos; 7-12 anos). Trata-se de um estudo longitudinal de um ano de seguimento. Atividades físicas e comportamentos sedentários foram relatados no questionário Consumo Alimentar e Atividade Física de Escolares (Web-CAAFE). As medidas repetidas foram realizadas no outono, inverno e primavera. Os desfechos avaliados foram: quantidade de atividades físicas diária (AFD) e de comportamentos sedentários (CS), frequências de atividades físicas leves (AFL), moderadas (AFM) e vigorosas (AFV ). Análises foram conduzidas via modelagem de equações de estimativa generalizada (GEE) (distribuição Poisson), com ajuste por temperatura ambiente e precipitação pluviométrica. Não houve variação sazonal estatisticamente significativa na AFD. No inverno, houve mais relatos de AFL (Coef² = 1,37; IC95%: 1,14-1,66) e de CS (Coef² = 1,16; IC95%: 1,05-1,29), enquanto AFV foram menos frequentes (Coef² = 0,83; IC95%: 0,71-0,97). AFV foram menos relatadas no outono (Coef² = 0,82; IC95%: 0,69-0,98). Sexo modificou o efeito das estações nas AFV, que entre meninos, ocorreram mais no outono (Coef² = 1,72 IC95%=1,16-2,56) e no inverno (Coef² = 1,84; IC95%: 1,26-2,69). Idade modificou efeito das estações sobre os CS. Durante o seguimento, houve mais CS na faixa etária 10-12 anos, porém, com diferença estatística significativa no outono e no início da primavera. O inverno favoreceu as AFL e os CS, mas restringiu as AFV, sobretudo entre meninas. Estudantes de 10-12 anos apresentaram mais CS, especialmente no outono e início da primavera

This one-year follow-up study analyzed the seasonal variation of physical activities and sedentary behaviors among children and adolescents, from public schools in the semiarid region of Bahia state (convenience sample, n = 462; 52.9% boys; 7-12 years). Physical activities and sedentary behaviors were reported in the Food Intake and Physical Activity of School Children Questionnaire ( WEB-CAAFE). Seasonal measure-ments were performed in fall, winter and spring. The outcomes were: daily amount of physical activities (DPA) and sedentary behaviors (SB), frequencies of light (LPA), moderate (MPA) and vigorous ( VPA) physical activities. The analyses were conducted via modeling of generalized estimation equations (GEE), with adjustment by temperature and rainfall. There was no statistically significant seasonal variation in DPA. During winter, there were more reports of LPA (Coef² = 1.37; 95%CI: 1.14-1.66) and SB (Coef² = 1.16; 95%CI: 1.05-1.29), while VPA was less frequent (Coef² = 0.83; 95%CI: 0.71-0.97). VPA occurred less in the fall (Coef² = 0.82; 95%CI: 0.69-0.98). Sex modified the effect of seasons on VPA: among boys, VPA occurred more frequently in the fall (Coef² = 1.72; 95%CI: 1.16-2.56) and winter (Coef² = 1.84; 95%CI: 1.26-2.69). Age modified the effect of the seasons on the SB: there were more SB in the 10-12 years age group, however, with a statistically significant difference only in the fall and early spring. LPA and SB increased during winter, but VPA decreased, especially among girls. Students aged 10-12 years had more SB in the fall and early spring

The need to become family caregivers: Grounded Theory

Aim: To discuss the relationship between the family and hospital discharge regarding manifestations, attitudes, feelings and practices. Method: The Theory Based on Data Approach, with semi-structured interviews and unsystematic participant observation was used as an approach. The research was undertaken in a public hospital in the city of Rio de Janeiro. Nine family members who are caregivers for a relative subsequent to a stroke, participated. Results: The categories "Facing the unexpected", "Recognizing the need for care after discharge" and "Realizing one's importance in the recovery of the relative" emerged. Discussion: The data showed an understanding on the part of the family with regard to the need to care for relative affected by stroke, highlighting the duality evident in this experience. Conclusion: The impact caused by the stroke and the need to take care of the relative at home highlights the importance of subjectivity and exchange of knowledge, being necessary to comply with the expectations and meanings of each family caregiver.
