Changes Over Time

This study examined two-year changes in patterns of activity and associations with body mass index (BMI) and waist circumference (WC) among adolescents. Inclinometers (activPAL) assessed sitting, sitting bouts, standing, stepping, and breaks from sitting. ActiGraph-accelerometers assessed sedentary time (SED), light-intensity physical activity (LIPA, stratified as low- and high-LIPA), and moderate-to-vigorous physical activity (MVPA). Anthropometric measures were objectively assessed at baseline and self-reported at follow-up. Data from 324 and 67 participants were obtained at baseline and follow-up, respectively. Multilevel mixed-effects linear regression models examined changes over time, and associations between baseline values and BMI and WC at follow-up. There were significant increases in BMI (0.6 kg/m2) and durations of prolonged sitting (26.4 min/day) and SED (52 min/day), and significant decreases in stepping (−19 min/day), LIPA (−33 min/day), low-LIPA (−26 min/day), high-LIPA (−6.3 min/day), MVPA (−19 min/day), and the number of breaks/day (−8). High baseline sitting time was associated (p = 0.086) with higher BMI at follow-up. There were no significant associations between baseline sitting, prolonged sitting, LIPA, or MVPA with WC. Although changes in daily activity patterns were not in a favourable direction, there were no clear associations with BMI or WC. Research with larger sample sizes and more time points is needed.

Purpose: This study used different analytic approaches to compare physical activity (PA) metrics from accelerometers (ACC) and a self-report questionnaire in upper elementary youth participating in the Fuel for Fun intervention. Methods: The PA questionnaire and ACC were assessed at baseline/preintervention (fall fourth grade), Follow-up 1/postintervention (spring fourth grade), and Follow-up 2 (fall fifth grade) of 564 fourth grade students from three elementary schools (50% females, 78% White, and 28% overweight or obese). Different analytic approaches identified similarities and differences between the two methods. Results: On average, self-report was higher than ACC for vigorous PA (range = 9–15 min/day), but lower than ACC for moderate PA (range = 24–30 min/day), light PA (range = 30–36 min/day), and moderate-to-vigorous physical activity (MVPA; range = 9–21 min/day). Spearman’s correlations for vigorous PA (.30, .26, and .32); moderate PA (.12, .13, and .14); and MVPA (.25, .25, and .24) were significant at each time point (all ps ≤ .01), whereas correlations for light PA were not significant (.06, .04, and .07; all ps > .05). In repeated-measures analyses, ACC and questionnaire measures were significantly different from each other across the three time points; however, change difference of the two measures over time was only 5.5 MVPA min/day. Conclusions: The PA questionnaire and ACC validated each other and can be used to assess MVPA in upper elementary school children in a similar population to the current study. However, each assessment method captures unique information, especially for light-intensity PA. Multiple PA measurement methods are recommended to be used in research and application to provide a more comprehensive understanding of children’s activity.

Intensity Physical Activity

Purpose. Research demonstrates that moderate-to-vigorous physical activity (MVPA) is associated with a reduced risk of all-cause mortality. Few studies have examined the effects of light-intensity physical activity on mortality. Therefore, the purpose of this study was to examine the association between objectively measured light-intensity physical activity and all-cause mortality risk. Design. Longitudinal. Setting. National Health and Nutrition Examination Survey 2003–2006 with follow-up through December 31, 2011. Subjects. Five thousand five hundred seventy-five U.S. adults. Measures. Participants wore an accelerometer for at least 4 days and completed questionnaires to assess sociodemographics and chronic disease information, with blood samples taken to assess biological markers. Follow-up mortality status was assessed via death certificate data from the National Death Index. Analysis. Cox proportional hazard model. Results. After adjusting for accelerometer-determined MVPA, age, gender, race-ethnicity, cotinine, weight status, poverty level, C-reactive protein, and comorbid illness, for every 60-minute increase in accelerometer-determined light-intensity physical activity, participants had a 16% reduced hazard of all-cause mortality (hazard ratio = .84; 95% confidence interval: .78–.91; p < .001). Conclusion. In this national sample of U.S. adults, light-intensity physical activity was inversely associated with all-cause mortality risk, independent of age, MVPA, and other potential confounders. In addition to MVPA, promotion of light-intensity physical activity is warranted.

AbstractBackground:As epidemiological studies have become more complex, demands for short, easily administered measures of risk factors have increased. This study investigates whether such a measure of physical activity is associated with the risk of death from all causes and death from specific causes.Methods:A prospective follow-up study of 11 090 men and women, aged 35–64 years, recruited from five UK general practices who responded to a postal questionnaire in 1989. Self-reported frequency of vigorous-intensity physical activity and data on confounding factors were collected at baseline survey. Death notifications up to 31 December 2001 were provided by the Office for National Statistics. The relative risk (and 95% confidence interval) of dying associated with each level of exposure to physical activity was estimated by the hazard ratio in a series of Cox regression models.Results:After > 10 years' follow-up there were 825 deaths among the 10 522 subjects with no previous history of angina or myocardial infarction. Participation in vigorous exercise was associated with a significantly lower risk of all-cause mortality. Similar associations were found for ischaemic heart disease and cancer mortality, although the relationships were not significant at the 5% level.Conclusions:Simple measures of self-reported vigorous physical activity are associated with the risk of future mortality, at least all-cause mortality in a somewhat selected group. Interpretation of the finding should be treated with caution due to the reliance on self-report and the possibility that residual confounding may underlie the associations. Because moderate-intensity physical activity is also beneficial to health, short physical activity questionnaires should include measures of such physical activity in the future.

Abstract Background The environmental correlates have been extensively studied in the last years, but most associations with physical fitness (PF) and body composition have been cross-sectional in nature. Objective This study aimed to determine if adolescents’ environmental perceptions associated with PF and body composition in a 2-year follow-up. Subjects Participants were 583 adolescents aged 12–18 years (299 girls) from the LabMed Physical Activity Study. Methods PF and body composition were assessed with the protocols of the ALPHA health-related fitness battery and environmental perceptions with the ALPHA environmental questionnaire. Linear regression models were used to determine the associations between environmental perceptions at baseline and PF and anthropometric measures at follow-up. Results Results showed that perceptions of distant facilities at baseline were associated with lower fitness at follow-up in boys. Also, boys’ lower study environment perceptions at baseline were associated with higher body composition at follow-up. Positive perceptions of a pleasant environment at baseline were associated with better fitness at follow-up in boys. Additionally, girls’ positive bike lanes availability and esthetics perceptions at baseline were associated with better body composition at follow-up. Conclusion Positive environmental perceptions at baseline are associated with better PF and body composition at follow-up.

Background:Prolonged sitting time is associated with numerous health outcomes; however, the role of cardiorespiratory fitness (CRF) in these relationships is largely unexplored. The cross-sectional association between reported sitting time and measured CRF was examined in a large study of healthy men and women.Methods:The analytic sample included 4658 men and 1737 women enrolled in the Cooper Center Longitudinal Study. Unadjusted and adjusted multivariable linear regression models were constructed to examine the association between sitting time and CRF, stratified by sex and meeting (or not) meeting physical activity (PA) guidelines.Results:In men, CRF was not associated with sitting time after adjustment for potential confounders. In contrast, for women, after adjustment there was a significant association between increased sitting time and lower CRF (P for trend <.001). When stratified by meeting or not meeting PA guidelines, there was no association between sitting time and CRF in men. In women, this relationship was statistically significant regardless of PA category (both P for trend < .05).Conclusions:These results suggest that the association between sitting time and CRF varies by sex. Further, meeting PA guidelines does not appear to modify this relation in either sex.

Abstract Study aim: The purpose of this study was to examine smartphone-using university students’ musculoskeletal system pain complaints, duration of smartphone and computer usage, participation in moderate-vigorous physical activities (MVPA), and prolonged sitting time.Material and methods: This study was conducted on Hitit University students (n = 387; 206 female, 181 male) in the province of Çorum. The International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Activity Assessment Ques­tionnaire (PAAQ) (sports/exercise activities section), and a personal information form prepared by the researchers were used as data collection tools. Descriptive statistics and the t-test were used to determine differences between groups. The Pearson chi-square test was used to examine the relationship between categorical variables.Results: It was observed that half of the participants with musculoskeletal system pain complaints (54.5%) feel the pain in all four areas (neck, shoulder, upper and lower back). There was no statistically significant relationship between physical activity intensity and pain complaint (p > 0.05). The students with musculoskeletal pain complaints spend more time on the smartphone and computer than students who do not have pain complaints (p < 0.05). During electronic device usage, the students who are in the low-intensity physical activity category spend more time sitting down than students in the moderate/vigorous intensity physical activity category (p < 0.05).Conclusions: In consequence, information can be provided about the importance of reducing sitting time during smartphone use and increasing the duration of moderate/vigorous-intensity physical activity (PA) so awareness can be raised on the issue among university students.

Background:Fundamental movement skills are a correlate of physical activity and weight status. Children who participated in a preschool intervention had greater movement skill proficiency and improved anthropometric measures (waist circumference and BMI z scores) post intervention. Three years later, intervention girls had retained their object control skill advantage. The study purpose was to assess whether at 3-year follow up a) intervention children were more physically active than controls and b) the intervention effect on anthropometrics was still present.Methods:Children were assessed at ages 4, 5, and 8 years for anthropometric measures and locomotor and object control proficiency (Test of Gross Motor Development-2). At age 8, children were also assessed for moderate to vigorous physical activity (MVPA) (using accelerometry). Several general linear models were run, the first with MVPA as the outcome, intervention/control, anthropometrics, object control and locomotor scores as predictors, and age and sex as covariates. The second and third models were similar, except baseline to follow-up anthropometric differences were the outcome.Results:Overall follow-up rate was 29% (163/560), with 111 children having complete data. There were no intervention control differences in either MVPA or anthropometrics.Conclusion:Increased skill competence did not translate to increased physical activity.

Abstract We examined cross-sectional associations between physical function and device-based (activPAL) sedentary patterns and physical activity. Physical function tasks included time to complete 5 chair stands and walk a 10-foot gait speed course. We estimated associations using linear regression models adjusting for age and sex; coefficients represent estimated change in mean activPAL measures associated with each second increase in gait/chair stands time. Longer gait speed times were associated with more total sitting time (b=0.19, p &lt; 0.01), fewer steps (b=-788.0, p&lt;0.001), fewer sitting breaks (b=-1.7, p&lt;0.01), and more prolonged sitting bouts (b=0.19, p&lt;0.01). Longer chair stand times were associated with more total sitting time (b=0.06, p&lt;0.001), less standing time (b=-0.04, p&lt;0.01), fewer steps (b=-176.8, p&lt;0.001), fewer sitting breaks (b=-0.45, p&lt;0.01), and more prolonged sitting bouts (b=0.07, p&lt;0.001). Prolonged patterns of sitting time and higher total sitting time, in addition to lower physical activity, were consistently associated with worse physical function.

Background:Adolescents require at least 60 minutes of daily moderate to vigorous intensity physical activity (PA) for optimum health benefits. Reduced active and increased sedentary time can adversely affect health independently. This study investigated the sedentary behavior and physical activity patterns of Singaporean adolescents.Methods:233 adolescents aged 13 to 15 years participated in the study. Accelerometry was used to assess the daily PA patterns for 3 weekdays and 2 weekend days consecutively. Height, weight, BMI, waist circumference and waist-hip ratio were determined as surrogate measures of health.Results:None of the participants achieved the recommended 60 minutes of daily moderate-to-vigorous physical activity (MVPA) on all 5 days. Significantly more time was spent engaging in sedentary activity compared with MVPA on both weekdays and weekends. MVPA and sedentary time were positively associated on weekdays after controlling for gender (P < .001). Weekday MVPA was positively associated with waist circumference (P < .001) and waist-hip ratio (P < .001).Conclusion:Singaporean adolescents fall substantially short of meeting the daily PA recommendations. Separate strategies to promote PA may be necessary for adolescents of differing weight status and gender. Pragmatic rather than idealistic targets to promote PA need to be set based on population-specific baseline data.

ObjectiveWe assessed associations between physical activity and lung function, and its decline, in the prospective population-based European Community Respiratory Health Survey cohort.MethodsFEV1 and FVC were measured in 3912 participants at 27–57 years and 39–67 years (mean time between examinations=11.1 years). Physical activity frequency and duration were assessed using questionnaires and used to identify active individuals (physical activity ≥2 times and ≥1 hour per week) at each examination. Adjusted mixed linear regression models assessed associations of regular physical activity with FEV1 and FVC.ResultsPhysical activity frequency and duration increased over the study period. In adjusted models, active individuals at the first examination had higher FEV1 (43.6 mL (95% CI 12.0 to 75.1)) and FVC (53.9 mL (95% CI 17.8 to 89.9)) at both examinations than their non-active counterparts. These associations appeared restricted to current smokers. In the whole population, FEV1 and FVC were higher among those who changed from inactive to active during the follow-up (38.0 mL (95% CI 15.8 to 60.3) and 54.2 mL (95% CI 25.1 to 83.3), respectively) and who were consistently active, compared with those consistently non-active. No associations were found for lung function decline.ConclusionLeisure-time vigorous physical activity was associated with higher FEV1 and FVC over a 10-year period among current smokers, but not with FEV1 and FVC decline.
