This study tested the effectiveness of individual exercise and sport counseling in a nonclinical setting. The COunseling based on Motives and goals in Exercise and sporT (COMET) approach focuses on individual motives and goals and aims to identify suitable activities. Participants experience different exercise and sport activities and reflect on them with a counselor, who applies motivational interviewing. A stratified randomized controlled design with 129 people was used. The intervention group took part in a counseling event, which included feedback on motives and goals, trial exercise and sport sessions, and structured reflection. Four weeks later, members of the group got a telephone booster. The control group received minimal intervention as written information. Results show that the counseling promoted motivational competence (η2 = .16), physical activity–specific self-control (η2 = .08), and the weekly volume of exercise and sport (η2 = .15), whereas it did not influence self-concordance. Further studies can investigate whether the COMET approach is also effective in other settings.

Background: The aim of this study was to investigate the effect of exercise during pregnancy on early childhood neurodevelopment (cognitive, motor, and language domains). Methods: A randomized controlled trial nested into the 2015 Pelotas (Brazil) Birth Cohort was conducted. Healthy pregnant women were enrolled between 16 and 20 weeks of gestation; 424 women and their children (intervention [n = 141]; control [n = 283]) were analyzed. An exercise-based intervention 3 times per week was delivered over 16 weeks. Child neurodevelopment and its domains were assessed at 1, 2, and 4 years. Standardized mean differences and 95% confidence intervals are presented. Results: No effects of exercise during pregnancy on child neurodevelopment and its domains at age 1 year were observed. Compared with the control group, children from women in the exercise group had higher language score at age 2 years (standardized mean differences = 0.23; 95% confidence intervals, 0.02 to 0.44) and higher cognitive score (standardized mean differences = 0.22; 95% confidence intervals, 0.03 to 0.41) at age 4 years. No effects of exercise during pregnancy were observed in the motor domain at 1, 2, and 4 years. Conclusions: No detrimental effects of exercise during pregnancy on child neurodevelopment were observed. In addition, these findings suggest that exercise during pregnancy can result in small benefits for language and cognitive development.

Background: Sufficient physical activity (PA) significantly contributes to the prevention and control of noncommunicable diseases. This study aims to determine the prevalence of insufficient PA and associated sociodemographic and lifestyle factors among adults aged 18–69 years in India. Methods: A national population-based, cross-sectional survey was conducted during 2017–2018 among 12,000 adults that adapted globally standard data collection tools. The data were weighted and analyzed using complex samples analysis. Logistic regression analysis was performed to identify the sociodemographic and lifestyle factors associated with insufficient PA. Results: Age standardized prevalence of insufficient PA among adults in India was 41.4%. A higher proportion of women (52.4%) and urban adults (51.7%) were not doing sufficient PA. Men (118.8 min) spent more time in PA per day than women (55.3 min). Higher odds of insufficient PA were significantly associated with unemployment (adjusted odds ratio [aOR] = 6.45), highest wealth quintile (aOR = 1.86), presence of central obesity (aOR = 1.24), and raised blood pressure (aOR = 1.22). Conclusion: This study provides the baseline prevalence of insufficient PA to monitor the set PA targets for India by 2025. The identified associated factors can guide policy makers to plan tailored interventions targeting high-risk groups and a multisectoral approach to promote PA.

Background: Demographic correlates of movement behaviors in infants are unclear. This study examined the longitudinal associations between demographic correlates and movement behaviors in infants. Methods: Participants were 411 parents of infants from the Early Movers project in Edmonton, Canada. Movement behaviors, infant and parental age, and nonparental care time were assessed using a parental questionnaire at 2, 4, and 6 months of age. Other infant and parental demographic variables were assessed at 2 months of age. Linear and generalized linear mixed models were conducted. Results: Infant age was associated with all movement behaviors except for restrained time. White infants and those with older parents had less tummy time but increased odds of having reading time. Infants of the most educated parents also had lower tummy time. Higher parental education and more siblings were associated with no screen time and longer infant sleep time. Infants with immigrant parent(s) were less likely to have reading time. No associations were found for infant sex, time spent in nonparental care, and parental marital status. Conclusion: Since no single demographic group demonstrated healthy patterns for all movement behaviors, promotion of a healthy balance of movement behaviors may be needed universally for all infants.

As smartphone and wearable device ownership increase, interest in their utility to monitor physical activity has risen concurrently. Numerous examples of the application of wearables in clinical and epidemiological research settings already exist. However, whether these devices are all suitable for physical activity surveillance is open for debate. In this commentary, we respond to a commentary by Mair et al. () and discuss four key issues specifically relevant to surveillance that we believe need to be tackled before consumer wearables can be considered for this measurement purpose: representative sampling, representative wear time, validity and reliability, and compatibility between devices. A recurring theme is how to deal with systematic biases by demographic groups. We suggest some potential solutions to the issues of concern such as providing individuals with standardized devices, considering summary metrics of physical activity less prone to wear time biases, and the development of a framework to harmonize estimates between device types and their inbuilt algorithms. We encourage collaborative efforts from researchers and consumer wearable manufacturers in this area. In the meantime, we caution against the use of consumer wearable device data for inference of population-level activity without the consideration of these issues.

Accelerometry-based monitors are commonly utilized to evaluate physical activity behavior, but the lack of contextual information limits the interpretability and value of the data. Integration of report-based with monitor-based data allows the complementary strengths of the two approaches to be used to triangulate information and to create a more complete picture of free-living physical behavior. This investigation utilizes data collected from the Free-Living Activity Study for Health to test the feasibility of annotating monitor data with contextual information from the Activities Completed Over Time in 24-hr (ACT24) previous-day recall. The evaluation includes data from 134 adults who completed the 24-hr free-living monitoring protocol and retrospective 24-hr recall. Analyses focused on the relative agreement of energy expenditure estimates between ACT24 and two monitor-based methods (ActiGraph and SenseWear Armband). Daily energy expenditure estimates from ACT24 were equivalent to the reference device-based estimate. Minute-level agreement of energy expenditure between ACT24 and device-based methods was moderate and was similar to the agreement between two different monitor-based methods. This minute-level agreement between ACT24 and device-based methods demonstrates the feasibility and utility of integrating self-report with accelerometer data to provide richer context on the monitored behaviors. This type of integration offers promise for advancing the assessment of physical behavior by aiding in data interpretation and providing opportunities to improve physical activity assessment methods under free-living conditions.
