Physical Activity Recall

Purpose:The purpose of this study was to examine the validity of a computerized 24-hour physical activity recall instrument (24PAR).Methods:Participants (n = 20) wore 2 pattern-recognition activity monitors (an IDEEA and a SenseWear Pro Armband) for a 24-hour period and then completed the 24PAR the following morning. Participants completed 2 trials, 1 while maintaining a prospective diary of their activities and 1 without a diary. The trials were counterbalanced and completed within a week from each other. Estimates of energy expenditure (EE) and minutes of moderate-to-vigorous physical activity (MVPA) were compared with the criterion measures using 3-way (method by gender by trial) mixed-model ANOVA analyses.Results:For EE, pairwise correlations were high (r > .88), and there were no differences in estimates across methods. Estimates of MVPA were more variable, but correlations were still in the moderate to high range (r > .57). Average activity levels were significantly higher on the logging trial, but there was no significant difference in the accuracy of self-report on days with and without logging.Conclusions:The results of this study support the overall utility of the 24PAR for group-level estimates of daily EE and MVPA.

Self-report recall questionnaires used to measure physical activity and dietary intake in children can be labour intensive and monotonous and tend to focus on either dietary intake or physical activity. The web-based software, Synchronised Nutrition and Activity ProgramTM (SNAPTM), was developed to produce a novel, simple, quick and engaging method of assessing energy balance-related behaviours at a population level, combining principles from new and existing 24 h recall methodologies, set within a user-friendly interface. Dietary intake was measured using counts for twenty-one food groups and physical activity levels were measured in min of moderate to vigorous physical activity (MVPA). A combination of the mean difference between methods, type II regression and non-parametric limits of agreement techniques were used to examine the accuracy and precision of SNAPTM. Method comparison analyses demonstrated a good agreement for both dietary intake and physical activity behaviours. For dietary variables, accuracy of SNAPTM (mean difference) was within ± 1 count for the majority of food groups. The proportion of the sample with between-method agreement within ± 1 count ranged from 0·40 to 0·99. For min of MVPA, there was no substantial fixed or proportional bias, and a mean difference between methods (SNAPTM – accelerometry) of − 9 min. SNAPTM provides a quick, accurate, low-burden, cost-effective and engaging method of assessing energy balance behaviours at a population level. Tools such as SNAPTM, which exploit the popularity, privacy and engagement of the computer interface, and linkages with other datasets, could make a substantial contribution to future public health monitoring and research.

The purpose of this study was to determine the extent to which sport education can provide students with sufficient opportunities for developing moderate-to-vigorous physical activity (MVPA). Nineteen seventh-grade boys (average age = 12.9 yrs.) participated in a 22-lesson season of floor hockey. For all students (both higher and lower skilled), students averaged a total of 31.6 min of MVPA during the season, or 63.2% of lesson time. Further, there was no significant difference according to skill level {33.4 min (Higher) vs. 30.4 min (Lower), nor were there any significant differences in MVPA levels across the phases of the season.

Improve Compliance

Background: To improve compliance and adherence to exercise, the concept of temporal consistency has been proposed. Before- and after-work are periods when most working adults may reasonably incorporate exercise into their schedule. However, it is unknown if there is an association between the time-of-day that exercise is performed and overall physical activity levels. Methods: Activity was assessed over 1 week in a sample of 69 active adults (n = 41 females; mean age = 34.9 [12.3] y). At the end of the study, participants completed an interviewer-assisted questionnaire detailing their motivation to exercise and their exercise time-of-day preferences. Results: Participants were classified as “temporally consistent” (n = 37) or “temporally inconsistent” (n = 32) exercisers based on their accelerometry data. The “temporally consistent” group was further analyzed to compare exercise volume between “morning-exercisers” (n = 16) and “evening-exercisers” (n = 21). “Morning-exercisers” performed a greater volume of exercise than “evening-exercisers” (419 [178] vs 330 [233] min by self-report; 368 [224] vs 325 [156] min actigraph-derived moderate to vigorous physical activity, respectively). Conclusions: Our findings suggest that active individuals use a mixture of temporal patterns to meet PA guidelines. Time-of-day of exercise should be reported in intervention studies so the relationship between exercise time-of-day, exercise behavior, and associated outcomes can be better understood.

Aim: To investigate the influence of genetic and environmental factors on physical activity levels. Methods: Data from 134 twins from Twins Research Australia, self-report and objective measures of physical activity were obtained by the International Physical Activity Questionnaire (IPAQ) (n = 110) and Actigraph (n = 120), respectively. Correlations were calculated for twin pairs stratified by zygosity (Monozygotic, MZ; Dizygotic, DZ) and using Spearman's correlation (rs) Results: Within-pair correlations were usually higher in MZ for the Actigraph (rs ranging from 0.34 [0.0 to 0.57] to 0.48 [0.22 to 0.68]) compared to IPAQ (rs ranging from -0.15 [-0.44 to 0.17] to 0.52 [0.25 to 0.72]. Correlations in DZ were lower for the Actigraph (rs ranging from -0.03 [-0.55 to 0.51] to 0.16 [-0.41 to 0.64]) compared to IPAQ (rs ranging from -0.11 [-0.59 to 0.43] to 0.50 [-0.01 to 0.81]). Correlations between Actigraph and IPAQ for all individuals were small for sedentary vs sitting time (rs = 0.28) and vigorous physical activity (rs = 0.27), but moderate for total physical activity (rs = 0.35). Conclusion: Within-family correlation of physical activity levels depends on the assessment, with less consistent results when its assessed by self-reported methods.

Objective In this study, we aimed to examine the association between physical activity patterns and sarcopenia in Arab men. Methods This cross-sectional study included 363 men (47.7 ± 15.4 years). We analyzed appendicular lean mass (ALM), handgrip strength test, and physical activity levels. ALM divided by height (meters) squared was calculated (ALM/Ht 2 ), and participants with −1 and −2 standard deviations below the sex-specific mean for Saudi young adults were considered to have sarcopenia class I and class II, respectively. Independent t-tests, analysis of variance, and Mann–Whitney U tests were performed to determine mean and median differences. Results We observed a significant difference between participants with and without sarcopenia in moderate-to-vigorous physical activity (MVPA); the correlation between ALM/H2 and MVPA was borderline significant. With a 1-hour/week increase in MVPA, ALM/Ht 2 increased by 0.30 kg/m2. Total and ALM, handgrip strength, and MVPA were significantly lower in participants age >60 years; fat mass and waist circumference were unchanged as compared with middle-aged participants. Conclusions We identified an association between time spent in recreational MVPA and lean muscle mass among Arab men. Future studies should examine the role of MVPA training programs on muscle mass and strength in older men.

Sampling Procedures

Maintenance of recommended physical activity levels is associated with favorable cardiovascular outcomes. Consequently, the American Heart Association (AHA) included physical activity in the new Ideal Cardiovascular Health concept. Although physical activity is known to decline with age, the age-specific probability of transitioning between AHA defined levels (ideal, intermediate, poor) is unclear. This knowledge could inform interventions seeking to increase or maintain physical activity levels across the life-course. We estimated age-specific prevalence of ideal (≥150 min/wk moderate or ≥75 min/wk vigorous or equivalent combination), intermediate (1-149 min/wk moderate or 1-74 min/wk vigorous or equivalent combination) and poor (0 min of moderate and vigorous) physical activity among adult (16+) European Americans (EA) and African Americans (AA) from the 2007-2010 NHANES (n=13,418) and Hispanic/Latino participants (H/L) from the 2008-2011 HCHS/SOL (n=14,291). Prevalence estimation incorporated data from identical NHANES and HCHS/SOL self-report questionnaires. We then used the prevalence estimates to calculate age, race, and sex-specific probabilities of transitioning between levels using Markov-type state-transition models. These models are designed to estimate transition probabilities from cross-sectional data assuming time-constant transitions, and have been updated to accommodate complex sampling procedures. The estimated 5-year probability of maintaining ideal physical activity levels remained high through the fourth decade of life, after which race and sex differences were observed. For example, the estimated 5-year probabilities of transitioning from ideal to intermediate physical activity levels were similar at age 40 for EA and AA men (1.2% [95%CI: 0.3, 2.3] vs. 2.2% [95%CI: 1.0, 3.6]), but by age 65 diverged to 5.3% (95%CI: 3.9, 6.9) vs. 11.6% (95%CI: 8.5, 15.2), respectively. During middle age, the estimated probability of transitioning from intermediate to poor physical activity levels was accelerated, although variation by race was noted. For example, the estimated probability of transitioning from intermediate to poor physical activity levels was <25% for EA, AA and H/L men through age 40, but by age 65 this increased to 32.6% (95%CI: 22.0, 44.1) for EA men and 41.1% (95%CI: 26.1, 58.0) for AA men while remaining low (11.1% (95%CI: 0.3, 24.3) for H/L men. Across all race-sex groups, individuals with poor physical activity levels had a 0% estimated probability of transitioning to ideal or intermediate physical activity levels, regardless of age. These results indicate need for interventions aimed at maintaining ideal physical activity levels beginning in young adulthood, particularly in AAs who transition from ideal levels at earlier ages than other race/ethnic groups. Innovative efforts may be needed for those with poor physical activity.

Physical Activity Recall

Recess is a frequent target in school-based physical activity (PA) promotion research but there are challenges in assessing PA during this time period. The purpose of this study was to evaluate the reliability and validity of a recess PA recall (RPAR) instrument designed to assess total PA and time spent in moderate to vigorous PA (MVPA) during recess. One hundred twenty-five 7th and 8th-grade students (59 females), age 12–14 years, participated in the study. Activity levels were objectively monitored on Mondays using different activity monitors (Yamax Digiwalker, Biotrainer and ActiGraph). On Tuesdays, 2 RPAR self-reports were administered within 1-hr. Test-retest reliability showed ICC = 0.87 and 0.88 for total PA and time spent in MVPA, respectively. The RPAR was correlated against Yamax (r = .35), Biotrainer (r = .40 and 0.54) and ActiGraph (r = .42) to assess total PA during recess. The RPAR was also correlated against ActiGraph (r = .54) to assess time spent in MVPA during recess. Mean difference between the RPAR and ActiGraph to assess time spent in MVPA during recess was no significant (2.15 ± 3.67 min, p = .313). The RPAR showed an adequate reliability and a reasonable validity for assessing PA during the school recess in youth.

Background:Physical activity levels of girls decline in adolescence, but little is known about changes in participation in specific types of physical activity. This study examined change in participation in specific activities during adolescence in girls.Methods:Girls (N = 398, age 13.6 ± 0.6 y at baseline, 58.5% African American) from 31 middle and 24 high schools in South Carolina completed the 3-Day Physical Activity Recall (3DPAR) in 8th, 9th, and 12th grades. Girls reported their predominant activity and its intensity level in each 30-min time block on the previous 3 d.Results:Vigorous physical activity declined from 45.4% in 8th grade to 34.1% in 12th grade. The probability of participating in several forms of vigorous physical activity in 12th grade was strongly associated with participation in those activities in 8th grade.Conclusion:Early-in-life participation in sports and other forms of vigorous physical activity are important to the maintenance of physical activity during adolescence in girls.

Background:Accurate assessments of physical activity and energy expenditure (EE) are needed to advance research on positive and negative graded walking.Purpose:To evaluate the validity of 2 SenseWear Armband monitors (Pro3 and the recently released Mini) during graded walking.Methods:Twenty healthy adults wore both monitors during randomized walking activities on a motorized treadmill at 7 grades (0%, ±5%, ±15%, and ±25%). Estimates of total EE from the monitors were computed using different algorithms and compared with values derived from indirect calorimetry methodology using a 2-way mixed model ANOVA (Device × Condition), correlation analyses and Bland-Altman plots.Results:There was no significant difference in EE between the 2 armbands in any of the conditions examined. Significant main effects for device and condition, as well as a consistent bias, were observed during positive and negative graded walking with a greater over- and under-estimation at higher slope.Conclusions:Both the armbands produced similar EE values and seem to be not accurate in estimation of EE during activities involving uphill and downhill walking. Additional work is needed to understand factors contributing to this discrepancy and to improve the ability of these monitors to accurately measure EE during graded walking.

Abstract:The aim of this study was to identify the levels of physical activity and sedentary behaviour of children and adolescents with sickle cell disease (SCA) compared to healthy individuals. A cross-sectional study with a quantitative approach was performed at a reference center for the treatment of patients with hemoglobinopathies in northeastern Brazil. Patients were recruited between October 2015 and January 2017. Eligible participants answered a Physical Activity Questionnaire for Older Children and Adolescents (PAQ-C) and were instructed to use an ActiGraph wGT3X-BT triaxial accelerometer for seven consecutive days. The analysis of the results was performed using the SPSS software (version 13.0). Differences between means were analysed using the Mann-Whitney U test and the chi-square test was used to evaluate the proportions of occurrence of categorical variables, comparing patient and controls groups. Among the 352 patients in the follow-up, 64 met the inclusion criteria and agreed to participate. Of those, 14 did not use the accelerometer during the 7 consecutive days and were excluded. 50 patients (and their 50 controls) were then evaluated. We observed a statistically significant difference between cases and controls in the variables “total time of moderate and vigorous physical activity” (p=0.009 and p=0.0001, respectively) and “daily mean of moderate and vigorous physical activity” (p=0.005 and p=0.003). There was also a significant difference among cases and controls in the following variables: “metabolic equivalent” (MET), with p=0.04, total of steps (p=0.04) and “total caloric expenditure” (p=0.0001), with the worst performances for the group of patients with SCA. Children and adolescents with SCA presented lower levels of physical activity than healthy children and adolescents, both when evaluated by the PAQs or by the accelerometer. The results suggest the need to develop specific programs aimed at promoting physical activity levels and reducing sedentary behaviour among young individuals with SCA.
