(PR = 1,60,1,52 and 1,93,1,25) and on non sport practitioners (RP = 1,80,1,14 and 2,15,1,16). For young people sports practitioners were not found associations between overweight and obesity with HBP (PR = 1,01, 0,82 and 1,09, 0,48
Objective:To analyze the agreement between two cutoff points for physical activity (300 and
420 minutes/week) and associated factors in youth.Methods:The study enrolled 738 adolescents of Londrina city, Paraná, Southern Brazil. The
following variables were collected by a self report questionnaire: presence of
moderate to vigorous physical activity, gender, age, father and mother education
level, with whom the adolescent lives, number of siblings, physical activity
perception, participation in Physical Education classes, facilities available to
physical activity practice and sedentary behavior. Prevalence of physical activity
between criterions were compared using McNemar test and the agreement was analysed
by Kappa index. Multivariate analysis was performed using Poisson regression with
robust variance adjustment was applied.Results:The prevalence for physical activity was significantly different: 22,3% for 300
minutes/week and 12,8% for 420 minutes/week (p<0,05), but the
agreement was strong (k=0,82, p<0,001). The variables gender,
father education, physical activity perception and sedentary behavior were
associated to physical activity in both analyzed criteria. Participation in
Physical Education class and facilities available to physical activity practice
were associated to physical activity only with 300 minutes/week cutoff point.Conclusion:Caution is suggested regarding cutoffs use for physical activity in
epidemiological studies, considering they can result in differences in prevalence
of physical activity and its associated factors.
This paper presents the bandwidth enhancement of a Planar Inverted F-Antenna (PIFA) up to 1.55 GHz as results of adding slots in the radiator element of the structure. The S-Parameters, gain, and radiation pattern after analyzed were used for comparison purpose with a published PIFA model. The simulations were made using the commercial software CST Design Studio. As result, a bandwidth enhancement of approximately 53% was achieved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
