“…Furthermore, SEM was used to assess the direct and indirect associations of C storage and climate, soil nutrient, and soil environment using the maximum likelihood method in the Amos software (version 17, Chicago, IL, USA). The results were shown as standardized regression coefficients (Barto et al, 2010;Cheng et al, 2014), which can identify the main factors for the spatial pattern of forest C storage. Spatial patterns in the allocation ratios of vegetation to soil (0-10 cm soil and 0-100 cm soil) were investigated at the 2 • latitudinal scale.…”

a b s t r a c tForests play an important role in sequestrating atmospheric CO 2 ; therefore, understanding the spatial variations and controlling mechanisms of forest carbon (C) storage is important. In this study, we collected data on forest C storage along a north-south transect of eastern China from literature published between 2004 and 2014. The collected data, which were from over 2000 plots, allowed us to explore the latitudinal patterns in forest C storage. The results showed that vegetation C storage decreased with increasing latitude, while soil C storage increased. This spatial pattern of vegetation C storage was more apparent for mature forests (forest age > 80 years). Furthermore, latitudinal patterns in forest C storage, both in vegetation and in soil, became stronger with increasing statistical scale, increasing from plot scale to latitudinal scale (2-5• ). However, total forest C storage (vegetation + soil) had no apparent latitudinal pattern. Interestingly, the allocation ratios of forest C storage between vegetation and soil had a negative logarithmic relationship with latitude. These results suggest that in eastern China, climatic factors control latitudinal patterns in the forest C storage of vegetation and soil, albeit in different ways (positive for vegetation and negative for soil), and also control the allocation ratios of forest C storage between vegetation and soil. Furthermore, the latitudinal patterns of forest C storage were opposite for vegetation and soil, resulting from the different climatic controlling mechanism.

“…A 2012 study carried out by Morton et al 35 showed that families that have transformational behaviors had health food consumption levels and greater levels of physical activity among adolescents. The level of physical activity of adolescents appears to be directly related to the practice of physical activity by their parents, as confirmed by Cheng et al 36 in a study of adolescents aged between 14 and 19 in Brazil, indicating that having parents who are sedentary can be a determining factor leading to intra-family overweight.…”

“…There are no studies in literature of which results found significant differences among adolescents 13. Adults with higher educational level are more likely to be active26 and their behavior and attitude have a strong influence on their children's habits 27. Based on this evidence, we emphasize the importance of including questions related to parental behavior when investigating PA-related behavior in adolescents, as they can lead to further explanations of this phenomenon 28…”

Objective:Verify the prevalence and sociodemographic and economic factors associated with behavior change stages for habitual physical activity practice in adolescents from Santa Catarina.Methods:Secondary analysis of a study on the Behavior of Adolescents from Santa Catarina (CompAC 2). Cross-sectional school-based study of 6,529 high-school students (males, n=2,903) from the state of Santa Catarina public education system in 2011, aged 15 to 19 years. Multinomial logistic regression (crude and adjusted) was used to measure the association.Results:The highest and lowest prevalence rates were found in the maintenance (43.9%) and precontemplation stages (7.0%), respectively. The stages of action, preparation and contemplation showed similar results: 16.2%; 17.0% and 15.6%; respectively. Male adolescents show higher prevalence in the maintenance stage in relation to females and these show a higher prevalence in preparation, contemplation and precontemplation. All the assessed variables (gender, age, area of residence, employment status, family income, maternal education and school grade), with the exception of school shift, were associated with at least one of the stages.Conclusions:A large proportion of adolescents are in the pre-adoption stages and most of these have the intention to start regular physical activity. With the exception of school shift, the assessed variables were associated with stages in different ways, showing different profiles in relation to sociodemographic and economic characteristics in each subgroup.

Physical activity in adolescents: analysis of the social influence of parents and friends

Abstract: Parents and friends have a social influence on adolescents' level of physical activity through the mechanism of behavior modeling or through social support, mediated by self-efficacy.
