Objectively Measured Physical Activity

The main goal of this study was to investigate the association between objectively measured physical activity and academic achievement in adolescents. Students in Grades 7 and 9 (N = 255) were included. Overall, we found no significant dose–response association between physical activity and academic achievement. However, in Grade 7 total physical activity volume (Total PA) was negatively associated with academic achievement, while moderate-to-vigorous physical activity (MVPA) was negatively associated with both academic achievement and mathematics performance. In contrast, in Grade 9 both Total PA and MVPA were positively associated with mathematics performance. In addition, the overall association between MVPA and academic achievement followed an inverted U-shaped curve. Finally, Total PA was positively associated with executive functioning, while executive functioning in turn mediated the associations between Total PA and both academic achievement and mathematics performance. These results indicate that the association between physical activity and academic achievement in adolescents is complex and might be affected by academic year, physical activity volume and intensity, and school grade.

Background. Regular physical activity in childhood and adolescent plays an important role in reducing the risk of cardiovascular health diseases, diabetes, and obesity in adulthood. However, little is known about physical activity levels (PA) and sedentary time among children and adolescents in Morocco. Objective. To examine gender, type of day, and age grade differences in objectively measured sedentary time, physical activity levels, and physical activity guideline attainment among children and adolescents in Morocco. Method. 172 children/adolescents (mean age = 10.92 ± 1.55 years, 49.4% are boys) were recruited for this study and wore a tri-axial accelerometer (GT3X+) for 7 consecutive days. Time spent in sedentary, PA levels, and daily steps were measured and compared according to gender, age grade, and the type of day (weekdays/weekends). Results. In weekdays children/adolescents spent more time in sedentary than weekends (p < 0.001). Boys were eight times more likely to meet the recommendation for at least 60 min of moderate to vigorous physical activity per day than girls (OR: 8.569; 95% [CI]: 4.23–17.32), p < 0.001. Conclusion. These findings highlight the need for effective and sustainable strategies and programs aiming to promote physical activity and to reduce sedentary behavior among children and adolescents in Morocco.

Objective: The objective of this study was twofold. First, analyze physical activity (PA) levels during physical education (PE) with different durations (45 and 90 minutes) according to student’s obesity status. Secondly, we examine the relative contribution of 45 and 90 minutes PE (45PE and 90PE) for the compliance of the daily PA recommendations according to the body mass index (BMI). Methods: Four public schools were analyzed. The sample comprised 472 youngsters (266 girls) aged between 10 and 18 years old. PA was assessed using an Actigraph accelerometer. The participants were categorized as non-overweight (NOW) and overweight/obese (OW) according to the sex-adjusted BMI. Results: The proportion of Moderate and Vigorous Physical Activity (MVPA) was lower than the 50% recommended by guidelines regardless the PE duration. Our data showed that only 26% of NOW and 13% of OW in the 45PE achieved the recommended levels while 17% of NOW and 11% of OW achieved the recommendation in 90PE. Overall, the 90PE had a higher absolute contribution for daily MVPA recommendations compliance than 45PE. Conclusion: During PE classes youngsters spent a reduced amount of time in MVPA, independently of their weight status.Resumen. Objetivo: Este estudio tiene un doble objetivo. En primero lugar, analizar los niveles de la actividad física durante la educación física con diferentes duraciones (45 y 90 minutos) de acuerdo con el estado de la obesidad de los alumnos. En segundo lugar, se analiza la contribución relativa de 45 y 90 minutos de la educación física para el cumplimiento de las recomendaciones diarias de actividad física según el índice de masa grasa. Métodos: cuatro escuelas públicas fueran analizadas. La muestra fue de 472 jóvenes (266 chicas) con edades entre los 10 y 18 años. La actividad física fue medida utilizando un acelerómetro Actigraph. Los participantes fueran clasificados como sin sobrepeso y con sobrepeso/obesidad de acuerdo con el índice de masa grasa ajustado al género. Resultados: La proporción de la actividad física moderada y vigorosa fue inferior al 50% recomendado por las recomendaciones independiente de la duración de la clase de educación física. Nuestros datos muestran que solo unos 26% de los niños sin sobrepeso y unos 13% de niñoss con sobrepeso/obesidad llegaron al los niveles recomendados en las clases de 45 min, mientras el 17% de los jóvenes sin sobrepeso y el 11% con sobrepeso/obesidad han logrado las recomendaciones en las clases de 90 min. En general, las clases de 90 min tienen una mayor contribución para cumplimiento de las recomendaciones diarias de actividad física moderada a vigorosa do que las clases de 45 min. Conclusión: Durante las clases de educación física los jóvenes tuvieran una cantidad reducida de tiempo en actividad física moderada a vigorosa, independiente de su estado de peso.

Abstract Background: In this manuscript, we aimed at investigating whether objectively measured lifestyle factors, including walking steps, sedentary time, amount of unforced physical activity, level of slight and energetic physical activity, conversation time, and sleep parameters altered before and during the COVID-19 pandemic among community-dwelling older adults.Methods: Data were obtained from a prospective cohort study conducted from 2015 to 2019 and a subsequent dementia prevention study undertaken in September 2020. Community-dwelling adults aged ≥65 years wore wearable sensors before and during the pandemic.Results: A total of 56 adults were enrolled in this study. The mean age was 74.2±3.9 years, and 58.9% (n=33) of the participants were female. The moderate and vigorous physical activity time significantly decreased and sedentary time significantly increased during the pandemic. Conclusions: This is the first study to demonstrate differences in objectively assessed lifestyle factors before and during the COVID-19 pandemic among community-dwelling older adults. The findings show that the pandemic has adversely affected physical activity among older adults living on their own in Japan.

The Relationship

Purpose: The authors examined the relationship between mother and child activity. Methods: The authors compared moderate–vigorous physical activity (MVPA) and sedentary time of low-income mothers with obesity and their 6- to 12-year-old children on week (WD) and weekend (WE) days. A total of 196 mother–child pairs wore accelerometers simultaneously for a week. Mothers completed questionnaires. Spearman correlation and multivariate regression were used. Results: WE MVPA (accelerometry) was significantly correlated between mothers with children aged 6–7 (rs = .35) and daughters (rs = .27). Self-reported maternal PA time spent with one of their children was significantly correlated with the WE MVPA of all children (rs = .21) and children aged 8–10 (rs = .22) and with the WD MVPA of all children (rs = .15), children aged 8–10 (rs = .23), aged 11–12 (rs = .52), and daughters (rs = .37), and inversely correlated to the WD sedentary time of all children (rs = −.21), children aged 8–10 (rs = −.30), aged 11–12 (rs = −.34), daughters (rs = −.26), and sons (rs = −.22). In multivariate regression, significant associations were identified between reported child–mother PA time together and child MVPA and sedentary time (accelerometry). Conclusions: Mothers may influence the PA levels of their children with the strongest associations found in children aged 6–7 and daughters. Mother–child coparticipation in PA may lead to increased child MVPA and decreased sedentary behavior.

ObjectivesTo understand how device-measured sedentary behaviour and physical activity are related to all-cause mortality in older men, an age group with high levels of inactivity and sedentary behaviour.MethodsProspective population-based cohort study of men recruited from 24 UK General Practices in 1978–1980. In 2010–2012, 3137 surviving men were invited to a follow-up, 1655 (aged 71–92 years) agreed. Nurses measured height and weight, men completed health and demographic questionnaires and wore an ActiGraph GT3x accelerometer. All-cause mortality was collected through National Health Service central registers up to 1 June 2016.ResultsAfter median 5.0 years’ follow-up, 194 deaths occurred in 1181 men without pre-existing cardiovascular disease. For each additional 30 min in sedentary behaviour, or light physical activity (LIPA), or 10 min in moderate to vigorous physical activity (MVPA), HRs for mortality were 1.17 (95% CI 1.10 to 1.25), 0.83 (95% CI 0.77 to 0.90) and 0.90 (95% CI 0.84 to 0.96), respectively. Adjustments for confounders did not meaningfully change estimates. Only LIPA remained significant on mutual adjustment for all intensities. The HR for accumulating 150 min MVPA/week in sporadic minutes (achieved by 66% of men) was 0.59 (95% CI 0.43 to 0.81) and 0.58 (95% CI 0.33 to 1.00) for accumulating 150 min MVPA/week in bouts lasting ≥10 min (achieved by 16% of men). Sedentary breaks were not associated with mortality.ConclusionsIn older men, all activities (of light intensity upwards) were beneficial and accumulation of activity in bouts ≥10 min did not appear important beyond total volume of activity. Findings can inform physical activity guidelines for older adults.

Increased skeletal muscle fat infiltration (i.e. myosteatosis) is now recognized as a major risk factor for cardio-metabolic diseases. Therefore, a lifestyle modification that reduces myosteatosis would be of great public health importance. However, studies examining the association of relevant lifestyle factors with this ectopic fat depot are lacking, particularly in African ancestry populations who have a very high burden of cardio-metabolic diseases. The aim of this study was to examine the relation between objectively measured physical activity and sedentary behavior with computed tomography measured calf muscle attenuation among middle-aged and elderly African-Caribbeans from the population-based Tobago Health Study. Preliminary analyses were conducted among 134 women (mean age 59 yrs, mean BMI 31.6 kg/m 2 ) and 355 men (mean age 62 yrs, mean BMI 28 kg/m 2 ). Physical activity was measured using the SenseWear Pro armband worn for 4-7 days. We calculated the mean duration of waking time engaged in light physical activity (LPA), moderate to vigorous activity (MVPA), and sedentary behavior (SB) per day. Skeletal muscle attenuation (mg/cm 3 ) reflects the fat content of the muscle such that greater skeletal muscle fat infiltration is reflected by lower attenuation. Women spent less time in LPA (146 vs. 270 min/day) and MVPA (15 vs. 41 min/day), but more time in SB (789 vs. 647 min/day) than men (all p<0.0001) after adjustments for gender differences in age. Muscle attenuation was lower among women compared with men (70.5 vs. 72.7 mg/cm3; age and BMI adjusted p<0.0001). In both women and men, muscle attenuation was positively correlated with the LPA and MVPA, and inversely with time spent in SB (spearman correlation coefficients (r) ranged from 0.21 to 0.39, all p<0.006 adjusted for age). Upon additional adjustment for BMI, in both women and men, the association of muscle attenuation with MVPA remained significant (r=0.21 and r=0.18, respectively, both p<0.03), but there was no association with LPA. Percent time spent in SB was associated with muscle attenuation only among women after additional adjustment for BMI (women: -0.16, p=0.052), and we also found a significant sex interaction effect of SB on muscle attenuation (p=0.035). Our preliminary findings suggest that there is significant association between MVPA and myosteatosis among middle-aged and elderly African Caribbeans. However, SB may only be relevant for myosteatosis among women. Future analyses will be conducted in a larger sample from this cohort to confirm our findings and to test for independence from other potential confounding factors, such as diet, sleep patterns, adiposity distribution, and diabetes.

BackgroundThere have been mixed findings regarding the relationship between walkability and level of physical activity in adults.MethodsParticipants from The REasons for Geographic and Racial Differences in Stroke (REGARDS) national cohort (N=7561) were used to examine the association between Walk Score and physical activity measured via accelerometry. The subsample included geographically diverse adults, who identified as black or white, and were over the age of 45. Linear regression was used to examine the direct effects, as well as the interaction, of Walk Score by sex, age and race.ResultsThe majority of participants lived in a ‘Very Car-Dependent’ location (N=4115). Only 527 lived in a location that was ‘Very Walkable/Walker’s Paradise’. Living in a location with a Walk Score of ‘Very Car-Dependent’ compared with ‘Very Walkable/Walker’s Paradise’ was associated with 19% (0.81; 95% CI 0.73 to 0.90) lower predicted minutes of moderate to vigorous physical activity per day, after adjustment for covariates. There was no evidence of statistically significant interactions between Walk Score and sex, age or race (p>0.05).ConclusionAccumulated daily time in moderate to vigorous physical activity was higher for participants living in neighbourhoods designated as ‘Very Walkable/Walker’s Paradise’. This effect was not moderated by sex, age or race of participants.

Objectively Measured Physical Activity

There is little evidence on how perceptions of the built environment may influence physical activity among post-stroke patients. This study aimed to explore the associations between perceived built environment attributes and objectively measured physical activity outcomes in community-dwelling ambulatory patients with stroke. This cross-sectional study recruited patients who could walk outside without assistance. We assessed both objectively measured physical activity outcomes such as number of steps and duration of moderate-to-vigorous physical activity (MVPA) with an accelerometer and the patients’ perceived surrounding built environment with the International Physical Activity Questionnaire Environmental Module. Sixty-one patients (67.0 years old) were included. The multiple linear regression analysis showed significant associations of the presence of sidewalks (β = 0.274, p = 0.016) and access to recreational facilities (β = 0.284, p = 0.010) with the number of steps taken (adjusted R2 = 0.33). In contrast, no significant associations were found between perceived built environment attributes and MVPA. These findings may help to suggest an approach to promote appropriate physical activity in patients with stroke depending on their surrounding built environment.
