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.

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.

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.

Purpose This study examined the associations of physical activity levels between parents and their pre-school children based on gender and weekday/weekend. Method A total of 247 parent-preschool child triads from Shanghai, China were analyzed. The children had a mean age of 57.5 ± 5.2 months. Both sedentary behavior and physical activity were measured in all participants using an ActiGraph GT3X+ accelerometer over seven consecutive days from Monday through the following Sunday. A multivariate regression model was derived to identify significant relationships between parental and child physical activity according to gender and weekday/weekend. Results There was a significant correlation between mothers’ and girls’ moderate-to-vigorous physical activity (MVPA) and total physical activity (TPA) on weekdays. Fathers’ MPVA levels correlated significantly with those of boys and girls, with paternal influence appearing to be stronger than maternal influence. However, there was not a significant correlation between fathers’ and children’s TPA. TPA levels of both mothers and fathers correlated with those of girls, but not with those of boys. Parental sedentary levels on the weekend correlated significantly with girls’ levels, but not with boys’ levels. Children’s physical activity levels on weekends were influenced more by fathers’ activity levels than by mothers’, while the opposite was observed on weekdays. Conclusion Sedentary behavior and physical activity levels of parents can strongly influence those of their preschool children, with maternal influence stronger during the weekdays and paternal influence stronger on the weekends. Parents’ activity levels influence girls’ levels more strongly than they influence boys’ levels.

Background: Moderate-to-vigorous physical activity (MVPA) offers many health benefits for preschoolers (2.5–5 y). In childcare, MVPA is predominantly accumulated outdoors, with higher rates purported among children within the first few minutes outside. The Supporting Physical Activity in the Childcare Environment intervention included shorter, more frequent outdoor play sessions; this study sought to explore children’s activity levels during various outdoor play schedules. Methods: During the final week of the Supporting Physical Activity in the Childcare Environment intervention, preschoolers wore an Actical™ accelerometer for 5 days during childcare and staff logged outdoor times. Separate linear mixed effects models were run to explore the effect of the intervention on preschoolers’ physical activity (total and MVPA) and sedentary time during outdoor play. Sex was entered as an interaction effect. Results: Preschoolers (n = 292) were significantly more active in the first 10 minutes outdoors compared with remaining time (P < .0083). For total outdoor time, children in the experimental group engaged in significantly less sedentary time than those in the control group (P < .017), and experimental group boys and girls engaged in higher MVPA than boys and girls in the control group (P < .017). Conclusions: Findings support scheduling more frequent outdoor play sessions in childcare to increase physical activity participation among young children.

Background:This study examines the relative contribution of social (eg, social support) and physical (eg, programs and facilities) aspects of worksite, church, and home settings to physical activity levels among adults in rural communities.Methods:Data are from a cross-sectional survey of 268 African American and Caucasian adults, ages 40–70, living in southwest Georgia. Separate regression models were developed for walking, moderate, vigorous, and total physical activity as measured in METs-minutes-per-week.Results:Social support for physical activity was modest in all 3 settings (mean scores 1.5–1.9 on a 4-point scale). Participants reported limited (<1) programs and facilities for physical activity at their worksites and churches. An interaction of physical and social aspects of the home setting was observed for vigorous and moderate physical activity and total METs. There were also interactions between gender and social support at church for vigorous activity among women, and between race and the physical environment at church for moderate physical activity. A cross-over interaction was found between home and church settings for vigorous physical activity. Social support at church was associated with walking and total METs.Conclusions:Homes and churches may be important behavioral settings for physical activity among adults in rural communities.

AbstractObjectiveTo investigate the dietary intake and physical activity of boys and girls aged 9–13 years, and the influence of peers on these behaviours.DesignCross-sectional study.SettingNine primary and secondary schools in south-west London.SubjectsA total of 315 children wore sealed pedometers, provided self-report measures of dietary intake and answered a questionnaire relating to peer influence. Anthropometric measures of height and weight were also obtained.ResultsObese children had the lowest reported energy intakes and the lowest step counts per day. Boys took significantly more steps per day than girls, however girls were closer to achieving their recommended cut-offs for physical activity. Girls had lower energy intakes per day and lower BMI Z-scores than boys, however both genders, across all age groups, had higher than recommended intakes of saturated fat. There were significant associations between peer influence and physical activity levels but not between peer influence and dietary intake.ConclusionsLow energy intake and physical activity levels but high saturated fat intakes among boys and girls across all age groups highlight the importance of promoting both physical activity and healthy food choices. The finding that peers have a significant effect on physical activity levels but not on dietary intake offers an important approach for the design of health promotion interventions and obesity prevention programmes. Such designs may be particularly beneficial for obese youth, since the low physical activity levels found could be a major contributing factor to the maintenance of the condition.

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.

AbstractObjectiveTo examine the association between breakfast consumption and physical activity in a well-characterised sample of English children.DesignCross-sectional study using food diaries to record breakfast consumption and accelerometry to assess physical activity.SettingNorfolk county, England.SubjectsChildren (n 1697) aged 9–10 years from the SPEEDY (Sport, Physical Activity and Eating behaviour: Environmental Determinants in Young people) study.ResultsBoys who consumed a poor-quality breakfast based on dairy product, cereal and fruit intakes spent approximately 7 min more time in moderate-to-vigorous physical activity (MVPA) during weekday afternoons and evenings compared with those who did not consume breakfast (P < 0·05). On weekend days, boys who consumed a poor- or good-quality breakfast spent approximately 6 and 5 min less time respectively being sedentary during the mornings compared with breakfast non-consumers (P < 0·05). Boys who consumed a good-quality breakfast spent almost 3 min more in MVPA during the morning on weekend days compared with non-consumers, and boys who consumed a poor- or good-quality breakfast were 22 % and 16 % more active overall respectively than breakfast non-consumers (P < 0·05). During the rest of the day, boys who consumed a good-quality breakfast spent about 11 min less time being sedentary (P < 0·05) and 7 min more time in MVPA (P < 0·01).ConclusionsAlthough some associations between breakfast consumption and physical activity were detected for boys, the present study does not provide strong evidence that failing to consume breakfast, or having a low energy intake at breakfast time, is detrimental to children's physical activity levels.

This cross-sectional study compared physical activity levels and barriers between 212 men and women with symptomatic peripheral artery disease. Physical activity was objectively measured by an accelerometer. Barriers to physical activity were obtained using a validated questionnaire. Women reported higher amounts of light physical activity (p < .001) and lower moderate–vigorous physical activity (p < .001) than men. Women more often reported barriers such as “not having anyone to accompany” (p = .006), “lack of money” (p = .018), “fear of falling or worsening the disease” (p = .010), “lack of security” (p = .015), “not having places to sit when feeling leg pain” (p = .021), and “difficulty in getting to a place to practice physical activity” (p = .015). In conclusion, women with symptomatic peripheral artery disease presented with lower amounts of moderate–vigorous activity and more barriers to activity than men. Strategies to minimize the barriers, including group actives and nonpainful exercises, are recommended for women with peripheral artery disease.

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.
