Association between physical inactivity in leisure, work, commuting, and household domains and nutritional status in adults in the capital cities of Brazil

Comparing Different Typologies of Physical Activities With a Focus on Motivation

There are numerous classifications of physical activities (PAs). However, they lack precise grouping criteria and tend to vary according to each author. Among other factors, the individual’s level of motivation is considered an important aspect of PA maintenance. In this study, we aimed to (1) compare several PAs according to intrinsic (Interest, Enjoyment, and Competence) and extrinsic (Appearance, Fitness/Health, and Social) motives and (2) analyze PAs with and without previous grouping to explore which PAs are more similar based on the different motivational subscales. We recruited 1,421 physically active Brazilian participants (mean age = 26.83, SD = 10.49). The participants stated which PA they practiced most frequently, and they answered the revised motivation for PA measure. The data were analyzed with multivariate general linear models and Kruskal–Wallis. We found that some PAs consistently differed from others regarding motivational subscales. For example, participants practicing Walking showed less Interest/Enjoyment and Competence motives than participants engaged in several other PAs. Pilates was highlighted by a particularly low level of Social motivation in comparison to other PAs. Furthermore, using the previously suggested categorization of PAs, we also showed consistent distinctions considering each motivational subscale. Specifically, one group of PA (categorized as more Complex, Team, Vigorous, Hybrid, and Combative) scored higher on intrinsic motivation, while the other group of activities (categorized as more Organized, Individual, Moderate, Strength, and Rhythmic) scored higher on Appearance and Fitness/Health motives. Our results thus provide initial evidence for possible new methods of grouping PA types that can improve maintenance behavior using motivation as a grouping factor.

Overweight and associated factors in Basic Education teachers during the Covid-19 pandemic: gender differentials

ABSTRACT Objective To estimate the prevalence of overweight among teachers in Minas Gerais during the Covid-19 pandemic and to review relevant gender associated factors. Methods Cross-sectional and analytical study, websurvey type, carried out with 15,641 teachers of public Basic Education in Minas Gerais, Brazil. Data collection took place from August to September 2020 with the use of a digital form. The dependent variable was overweight, calculated by the body mass index using the teachers’ self-reported weight and height. Poisson regression was used, with robust variance. Results Among the participating teachers, 52.4% were overweight. When stratified by gender, 51.1% women and 58.2% men were considered overweight, with a significant difference between them (p<0.001). There was a higher prevalence of overweight among women in the age group of 30 to 59 years (PR=1.39) and in women 60 years or older (PR=1.45) living in the metropolitan region of the state (PR=1.06) who had children (PR=1.19), who were not exercising (PR=1.09) and with a worse dietary pattern during the pandemic (PR=1.12), much afraid of Covid-19 (PR=1.04) and with anxiety and/or depression during the pandemic (PR=1.14). Among men, there was a higher prevalence of overweight among those individuals aged 30 to 59 years (PR=1.19), who lived with a spouse (PR=1.15) working more than 40 hours per week (PR=1.12) and those with the worst dietary pattern during the pandemic (PR=1.10). Conclusion The results showed a 52.4% prevalence of overweight teachers and different associated factors between the genders.
