OBJECTIVE To analyze physical activity during adolescence in participants of the 1993 Pelotas Birth Cohort Study, Brazil. METHODS Data on leisure time physical activity at 11, 15, and 18 years of age were analyzed. At each visit, a cut-off point of 300 min/week was used to classify adolescents as active or inactive. A total of 3,736 participants provided data on physical activity at each of the three age points. RESULTS A significant decline in the proportion of active adolescents was observed from 11 to 18 years of age, particularly among girls (from 32.9% to 21.7%). The proportions of girls and boys who were active at all three age points were 28.0% and 55.1%, respectively. After adjustment for sex, economic status, and skin color, participants who were active at 11 and 15 years of age were 58.0% more likely to be active at 18 years of age compared with those who were inactive at 11 and 15 years of age. CONCLUSIONS Physical activity declined during adolescence and inactivity tended to track over time. Our findings reinforce the need to promote physical activity at early stages of life, because active behavior established early tends to be maintained over time.

We aimed to measure the prevalence of physical inactivity (PI) during leisure time and to identify variables associated with it in a southern Brazilian adult population. A population-based cross-sectional study was carried out, covering a multiple-stage sample of 1,968 subjects aged 20-69 years. Weekly participation in leisure-time physical activity was addressed. For each activity, energy expenditure was calculated using data on duration, metabolic equivalent, and body weight. Energy expenditures of individual activities were summed to give a weekly total. PI was defined as fewer than 1,000 kilocalories per week. The prevalence of PI was 80.7% (95%CI: 78.9-82.4). After adjusted analyses, the following variables were positively associated with the outcome: female gender, age, living with a partner, and smoking. Schooling and economic status were inversely associated with PI. Chronically undernourished individuals were significantly more likely to be inactive. We found no differences according to skin color or alcohol consumption. In conclusion, the prevalence of PI in this adult population was higher than in populations from developed countries, but the associated variables were similar.

Background: Physical activity levels decrease during pregnancy, and the time course of return to prepregnancy levels is unclear. This study aimed to describe changes in leisure-time physical activity (LTPA) and sitting time from 16 to 24 weeks of pregnancy to 12, 24, and 48 months postpartum in women with different education levels in Brazil. Methods: Data from 4000 mothers of children enrolled in the 2015 Pelotas (Brazil) Birth Cohort were analyzed. The women were interviewed between 16 and 24 weeks of pregnancy and when their children were aged 12, 24, and 48 months. The LTPA and sitting time were self-reported. Results: Only 15.7% of the women reported any LTPA during pregnancy; this declined to 7.9% at 12 months postpartum; it was 16.8% at 24 months and 23.2% at 48 months. On average, participants spent a mean (SD) of 6.4 (3.9), 4.2 (3.2), 4.3 (3.3), and 4.4 (3.3) hours per day sitting during pregnancy, and at 12, 24, and 48 months after the birth, respectively. Both any LTPA and high sitting (8+ h/d) were consistently higher among women with higher education. Conclusion: After 24 months postpartum, LTPA levels had returned to or exceeded pregnancy levels, but sitting time remained lower than during pregnancy.

Background:The aim of this study was to evaluate changes in leisure-time physical activity (LTPA) and its correlates from prepregnancy to the postpartum period in mothers enrolled in a Brazilian birth cohort study. Our hypothesis was that LTPA would decline considerably during pregnancy.Methods:Maternal LTPA in the 3 months before pregnancy and during each trimester of pregnancy was assessed soon after delivery. A follow-up visit was conducted 3 months later. Weekly frequency and duration of each session of LTPA in a typical week were assessed for each period and a cut-off point of 150 minutes per week was used to classify women as active or not.Results:The proportion of women active in leisure time declined from 11.3% in the prepregnancy to 2.3% in pregnancy and 0.1% in the postpartum period (P for trend <0.001). When considering any LTPA practice, the decline ranged from 15.4% to 4.4% and 7.5% (p for trend <0.001), respectively. Higher income, higher education and lower parity were the main predictors of LTPA practice.Conclusions:LTPA declined considerably during pregnancy and did not return to prepregnancy levels at 3 months postpartum. Mothers must be advised on the benefits of LTPA prepregnancy, during, and postpregnancy.

Abstract Background We aimed to test which life course model best described the association between leisure-time physical activity (LTPA) and multimorbidity at age 55. We analyzed data from birth to age 55 using the database from the 1958 National Child Development Survey. Methods Multimorbidity was considered as the presence of more than one chronic condition. LTPA was measured through questionnaires from 1965 (age 7) to 2013 (age 55), which were applied in eight different occasions. We compared the fit of a series of nested adjusted logistic regression models (representing either the critical, accumulation or sensitive period models) with a fully saturated model. Data were reported as odds ratio (OR) and 95% confidence interval (CI). Results From an eligible sample of 15,613 cohort members, 9137 were interviewed in the latest sweep (58.5%). Men were more physically active than women at ages 11, 16, and 23 (p < 0.001). LTPA every day in the week was more frequent in women than men in ages 33, 42, and 50 (p < 0.001). The prevalence of multimorbidity at age 55 was 33.0% (n = 2778). The sensitive analysis revealed that LTPA during adolescence (OR: 0.83; 95% CI: 0.70, 0.98) and mid adult life (age 50 and 55; OR: 0.82; 95%CI: 0.69, 0.98) have a stronger effect on the risk for multimorbidity at age 55 considering all other life stages in the model. Also, adolescence showed a critical independent effect on the risk for multimorbidity (OR: 0.82; 95%CI: 0.70, 0.97). No difference was found between those models. Conclusions These data support the notion of a protective physical activity “legacy” at early ages of childhood against multimorbidity at older ages. We highlight the need for LTPA promotion through intervention tailored especially on schooling and older ages in order to reduce the burden of multimorbidity.

Background: This study aims to describe changes in gender and wealth inequalities in leisure-time physical activity (PA) of Brazilians during a 6-year interval. It also aims to evaluate inequalities regarding PA public programs awareness, participation, and access to public spaces for PA. Methods: Data from 2 population-based surveys conducted in 2013 and 2019 were used. Leisure-time PA prevalence was assessed considering those reporting ≥150 minutes per week. The authors evaluated gender inequalities calculating differences and ratios, and wealth inequalities using the slope index of inequality and the concentration index— assessing changes over time. Results: National levels of leisure-time PA increased from 2013 to 2019, and an increase in inequalities was observed; women and the poorest groups still presented lower prevalence. A decline in socioeconomic inequalities was observed from 2013 to 2019 regarding the availability of public spaces and awareness about public programs. However, outcomes remained more common among the richest group. Inequalities did not vary for participation in public programs. Conclusion: Although leisure-time PA increased from 2013 to 2019 at a national level, there were no improvements in gender inequalities, and wealth inequalities worsened over time. Indicators of public strategies for PA increased for the population, but inequalities remain.

This study examined whether levels of chronic disease risk factors change over time, and whether leisure-time physical activity (LTPA) can explain any of the variation in those risk factors that change, in a sample of community-dwelling people living with spinal cord injury (SCI) in or near Hamilton, Ontario, Canada. LTPA was measured using the Physical Activity Recall Assessment for People with SCI at baseline (n = 76 adults with chronic (≥1 year) paraplegia or tetraplegia), at 6 months (n = 71) and at 18 months (n = 63). Body mass index, waist circumference at the lowest rib (WClowest rib) and iliac crest (WCiliac crest), fat mass, blood pressure, and biochemical data were collected at all 3 time points. Women’s BMI was higher at baseline (least square means (LSM) = 26.2 ± SE = 1.56 kg·m–2, p = 0.0004) and 6 months (25.9 ± 1.6, p = 0.0024) than at 18 months (22.1 ± 1.72). Men’s WClowest ribincreased from baseline (92.1 ± 1.87 cm) to 18 months (93.6 ± 1.87, p = 0.0253). Women who were active vs. inactive at baseline had a lower BMI at 6 months (23.1 ± 2.91 vs. 29.7 ± 2.52, p = 0.0957) and WCiliac crestat 6 months (82.8 ± 6.59 vs. 97.7 ± 5.10, p = 0.0818). Women who were active vs. inactive at 6 months had a lower WCiliac crestat 18 months (73.4 ± 14.3 vs. 102.5 ± 6.41, p = 0.0723). There was little change in traditional risk factors over 18 months. Future studies should extend beyond 18 months in a larger sample, and explore traditional vs. novel risk factors and onset of cardiovascular disease and diabetes in the SCI population.
