Less than half of adolescents reach the recommended 300 minutes per week of physical activity (PA). Physical education classes and sports participation provide opportunities for adolescents to accumulate more time for PA practice; however, little is known about the influence of these variables on the level of total physical activity of adolescents. The aim of this study was to investigate the association between the practice of physical education (PE) in schools and sports activities (SA) with the practice of total PA of adolescents. The study was cross-sectional and involved 467 adolescents of high school (15.8 ± 0.9 years-old) from the city of Rio Claro, in the State of São Paulo. Participants completed the Physical Activity Questionnaire to Older Children (PAQ-C) and questions related to the practice of PE and SA in schools. We performed a logistic regression with p<0.05 using SPSS. Girls had lower prevalence of PA than boys, 9.4% and 26.8%, respectively. Boys who did not participate of PE classes (OR=0.25, 95% CI=0.09-0.66) and SA in schools (OR=0.34, 95% CI=0.12-0.95) were less likely to be active in PA than boys who practiced these activities. The participation in PE classes or engagement in some SA were positively associated with the practice of total PA in boys.

The scope of this article is to evaluate risk and protection factors for the development of 1-year-olds assisted at family health care units. It is a cross-sectional study involving 65 children of approximately 1 year of age and their mothers attended at two family health care units. The development was assessed using a developmental screening test (Denver II). The mothers filled out the SRQ-20 questionnaire to identify common mental disorder (CMD) indicators. After data collection, descriptive and inferential statistical analysis was performed. Global development was at risk in 43.1% of the children evaluated, and the most affected areas were language and fine motor development; 44.6% of mothers had results indicative of CMD when the child was 1 year of age. In bivariate analysis, reported depression, smoking, infections in pregnancy, CMD after birth and working outside the home were significantly associated with the children's development. After full statistical analysis, CMD was revealed as being a risk factor, and working away from home as being a protection factor. In order to increase the chances of success of programs targeted for children at health care units and avoiding the risk of impaired development, it is important to focus on two aspects: children's stimulation and maternal mental health.

The plants are subject to the conditions of multiple stresses, such as water and salt stress, which limit their development and their chances of survival. Aware of the factors that control seed germination can generate support for management strategies of weed species. The objective of this study was to evaluate the possible effects of water stress caused by PEG and NaCl solutions on germination of wild Raphanus raphanistrum and Senna obtusifolia seeds. The seeding was done with four repetitions of 50 seeds on moistened paper with solutions of polyethylene glycol (PEG 6000) and NaCl at osmotic potentials of 0.0, -0.2, -0.4 and -0.8 MPa. The germination test was conducted at 25 degrees C in the presence of light, evaluating the first test score to seven days after sowing, and weekly, germination (normal seedlings) until 35 days; it was also calculated the index germination rate. The results allowed the conclusion that water stress by PEG causes a greater reduction in force, speed of germination and accumulated germination of seeds of Raphanus raphanistrum and Senna obtusifolia seeds. The Senna obtusifolia was more tolerant to water stress.
