Objectively Measured Physical Activity

Aim. To examine the association between objectively measured physical activity (PA) and body mass index (BMI) in preschool children.Methods. The study comprised 281 children (55.9% boys) aged from 4 to 6 years. PA was measured by accelerometer. Children were categorized as non-overweight (NOW) and overweight/obese (OW) according to the sex-adjusted BMI z-score (<1 and≥1, resp.).Results. Total and moderate intensity PA were not associated with BMI. We observed that a higher proportion of OW children were classified as low-vigorous PA compared to their NOW peers (43.9 versus 32.1%, resp.,P>.05). Logistic regression analysis showed that children with low-vigorous PA had higher odds ratio (OR) to be classified as OW compared to those with high-vigorous PA (OR=4.4; 95% CI: 1.4–13.4;P=.008) after adjusting for BMI at first and second years of life and other potential confounders.Conclusion. The data suggests that vigorous PA may play a key role in the obesity development already at pre-school age.

Objectively Measured Physical Activity

This study examined correlates of objectively measured physical activity (PA) in a diverse sample of preschool children (age 3–5 years; n = 331). Accelerometer min·hr−1 of moderate-to-vigorous physical activity (MVPA) and nonsedentary activity (NSA) were the outcome measures. Correlations among potential correlates and PA ranged from r = −0.12−0.26. Correlates in the final MVPA model were age, race, sex, BMI Z score, and parent perception of athletic competence, explaining 37% of the variance. The NSA model included the latter two variables, explaining 35% of the variance. Demographic factors were correlates of PA; parent perceptions of children’s competence may be important regarding preschoolers’ PA.

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 Objective To study the associations of objectively measured physical activity (PA) and sedentary time (ST) with the combined outcome of incident stroke, myocardial infarction (MI) or all-cause mortality in older adults. Methods N = 3343 men and women aged 70 who participated in a health survey between 2012 and 2017 were included. Actigraph GT3X+ accelerometers were used to measure light-intensity PA (LPA), moderate-intensity PA (MPA) and ST for 1 week. Incident cases of cardiovascular disease (CVD) in terms of stroke or MI, and all-cause mortality were identified using national registers. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using multivariable-adjusted Cox regressions. Results During a mean follow-up of 2.7 years (0.1–5.6), there were 124 events of CVD or all-cause mortality. After adjusting for potential confounders and mediators, every 30-min/day increment in LPA was associated with 11% lower risk of CVD or all-cause mortality (HR 0.89, 95% CI 0.82–0.97), and every 30-min/day increment in MPA was associated with 36% lower risk (HR 0.64, 95% CI 0.48–0.84). Every 1-h/day increment in ST increased the risk of the outcomes by 33% (HR 1.33, 95% CI 1.14–1.56), although there was no significant association among participants who performed ≥ 30 min/day MPA (HR 1.11, 95% CI 0.82–1.50, P = 0.034 for interaction). None of the associations were modified by sex (P > 0.4 for all). Conclusion Objectively measured LPA and MPA are each associated with lower risk of stroke, MI or all-cause mortality in 70-year-old individuals, while ST is associated with increased risk. The greatest risk reduction is observed for MPA, which also appears to attenuate some of the increased risks associated with ST.

Purpose: The purpose of this study was to assess the relationship between the walkability/bikeability of college campuses and students’ body mass index (BMI) with student physical activity (PA) attitudes and behaviors as potential mediators. Design: Cross-sectional. Setting: Thirteen university campuses. Participants: A total of 1384 student participants. Measures: Walkability/bikeability environmental score (ES): 12-item audit assessed an average of 44 path segments per campus. Students were measured for height and weight and completed online surveys. Physical activity stage of change/behavior intentions were assessed using the transtheoretical model. The Cognitive Behavioral Physical Activity Questionnaire assessed outcome expectations, self-regulation, and personal barriers. International Physical Activity Questionnaire assessed walking-, moderate-, and vigorous-intensity PA. Analysis: Descriptive statistics, zero-order correlations, and path analysis with maximum likelihood estimation. Results: The overall model fit was good with χ2 of 171.388 ( df = 18), P < .001, comparative fit index value of .95, and a root mean square of approximation of .079. After controlling for gender, there was a direct negative association between walkability/bikeability ES and BMI (β = −.085) and positive association between personal barriers and BMI (β = .134). Walkability/bikeability ES was positively associated with walking-intensity PA (β = .010). Self-regulation was positively associated with moderate-intensity PA (β = .213), which, in turn, was negatively associated with BMI (β = −.057). Conclusions: The ease of walking and biking on a campus was related to college students’ walking behavior and their BMI. Students’ PA behavioral intentions were associated with moderate PA and lower BMI. These results provide evidence to focus on policies and structural supports for walkable/bikeable environments to supplement and enhance interventions encouraging individual behavior change for PA and weight management.

Research background and hypothesis. The objective methods for measuring PA are used more and more widely in various research studies all over the world. To our best knowledge, this pilot study is the first attempt in Lithuania to objectively assess physical activity of adolescents with an ambition to develop a more accurate methodology in assessing physical activity. Research aim of this study was to analyze the objectively measured weekly physical activity results of adolescent boys.Research methods. The PA of schoolboys was measured using Tri-axis ActiTrainer Activity Monitors. Boys were asked to wear the monitors for the whole week. The level of the intensity of PA was determined by calculating energy consumption in METs. Based on the frequency of vigorous  and moderate PA per week, the participants of this study were devided into PA groups. Research results. All of the schoolboys experienced LPA on each of the assessed days. MPA on each day was experienced by 59.6 % of the boys. No participants achieved VPA on a daily basis. The frequency of MPA and VPA experienced most often was 5–7 and 1–3 days per week, respectively. The total PA measured during the week was largely comprised by LPA, i. e. 79.8%; MPA and VPA were 18.8 and 1.4%, respectively.Discussion and conclusion. Boys who achieve VPA, have a greater total PA during the week than those boys who do not experience VPA. If boys achieve VPA on more than 2 days during the week, even if it is just for 10 min, there is a significant increase in the total amount of weekly PA as well as a decrease in their body mass index (BMI). Boys’ who do not experience MPA at least for 6 days/week, the total amount of weekly PA decreases.Keywords: PA frequency, PA intensity, PA volume.

Authoritative Parenting Style

The purpose of the current study was to determine the influence of parenting style on body mass index (BMI) percentile, physical activity (PA), and sedentary time (ST) in children. Accelerometers were used to assess PA and ST in 152 fifth-grade children. Parenting style was assessed by the child participants’ responses to modified questions from the Parenting Style Inventory II and dichotomized as authoritative or non-authoritative. Multiple linear regression analyses were utilized to identify significant predictors of outcomes of interest. Parenting style did not predict ST or any intensity of PA; however, BMI percentile and gender were significant predictors of moderate-intensity PA, vigorous-intensity PA, and moderate-to-vigorous intensity PA ( P < .01). BMI percentile was predicted to be lower in females with authoritative mothers ( P < .01). While authoritative and non-authoritative parenting style did not predict objectively measured PA or ST in early adolescents, authoritative parenting style did predict BMI percentile in female participants.
