Arterial stiffness is a precursor for the development of hypertension and premature cardiovascular disease (CVD). Physical activity has been associated with lower arterial stiffness among largely White populations, but the types of activity required and whether these findings apply to Black adults remain unknown. We examined whether physical activity levels were associated with arterial stiffness among Black adults in two independent cohorts. In the Morehouse-Emory Cardiovascular (MECA) Center for Health Equity, 378 Black adults (age 52.8 ± 10.3, 39.7% male) without known CVD living in Atlanta, GA were recruited. Arterial stiffness was measured as pulse wave velocity (PWV). Total and domain-specific physical activity were assessed by self-report. Multiple linear regression models were used to investigate differences across physical activity levels after adjusting for age, sex, CVD risk factors, and socioeconomic status. Findings were validated in an independent cohort of Black adults ( n = 55, age 50.4 ± 9.2, 23.6% male). After adjustment for covariates, lower arterial stiffness was associated with higher self-reported levels of sport/exercise (6.92 ± 1.13 vs 7.75 ± 1.14, p < 0.001, highest vs lowest quartile) and home/life activities (7.34 ± 1.24 vs 7.73 ± 1.07, p = 0.04, highest vs lowest quartile), but not work, active living, or the overall physical activity scores. These findings were replicated in the independent cohort where higher levels of sport/exercise remained associated with lower arterial stiffness (6.66 ± 0.57 vs 8.21 ± 0.66, p < 0.001, highest vs lowest quartile). Higher levels of sport/exercise and home/life-related physical activities (in comparison to occupational physical activity) are associated with lower arterial stiffness in Black adults.

Introduction: Arterial stiffness is a precursor for development of hypertension and premature cardiovascular disease (CVD). Physical activity has been associated with lower arterial stiffness among largely White populations, but the types of activity required and whether these findings apply to Blacks remain unknown. We examined whether physical activity levels were associated with arterial stiffness among Blacks in two independent cohorts. Methods: In the Morehouse-Emory Cardiovascular (MECA) Center for Health Equity, 458 Black adults (age 53 ± 10, 39% male) without known CVD living in Atlanta, GA were recruited. Arterial stiffness was measured as pulse wave velocity (PWV) using applanation tonometry (Sphygmocor Inc). Total and domain specific physical activity (work, active living, household, and sport/exercise) were assessed by self-report using the Jackson Heart Study Physical Activity Questionnaire. Multiple linear regression models were used to investigate differences after adjusting for age, gender, blood pressure, diabetes, and smoking. Change in the Framingham Risk Score (FRS) was tested as a potential mediator. Findings were validated in the Emory-Morehouse Partnership to Reduce Cardiovascular Health Disparities (META-Health) --another independent cohort of Black adults (n=60, age 50 ± 10, 25% male). Results: Lower arterial stiffness was associated with higher self-reported levels of sport/exercise (Beta = -0.54 [-1.03, -0.05], p=0.03, highest versus lowest quartile), but not work, active living, household-related physical activities, or the overall physical activity scores. 26.9% of this improvement appeared to be mediated through changes in FRS factors. These findings were confirmed in an independent group of Blacks in META-Health where higher levels of sport/exercise remained associated with lower arterial stiffness (Beta = -1.46 [-2.80, -0.12], p=0.03, highest versus lowest quartile). Conclusion: Higher sport/exercise related physical activity is associated with lower arterial stiffness in Blacks, an association that is only partially attributable to a lower traditional CVD risk factor burden.

Active commuting to and from school (ACS) could help to increase daily physical activity levels in youth; however, this association remains unknown in Ecuadorian youth. Thus, the aims of this study were (1) to determine the patterns of commuting to and from school and (2) to analyze the associations between ACS, physical activity (PA), and sedentary habits in Ecuadorian youth. A total of 732 students (65.3% males), aged 10–18 years (children = 246, young adolescents = 310, older adolescents = 162) from the central region of Ecuador participated in this study. A self-report questionnaire, including the usual mode and frequency of commuting, distance from home to school (PACO-Questionnaire), and PA and sedentary habits (YAP-Questionnaire), was used. Most of the sample lived ≤2 km from school; however, they were mainly passive commuters (96%). The most common mode of commuting was by car (to school = 43.4%, from school = 31.6%; p < 0.001). Children presented significantly higher scores (0–4) in PA outside school and total PA compared with older adolescents (2.20 ± 0.97 vs. 1.97 ± 0.96; p = 0.013 and 2.30 ± 0.76 vs. 2.09 ± 0.74, p = 0.019, respectively), as well as the lowest scores in sedentary habits (1.51 ± 0.65, p < 0.001). PA at school and total PA were positively associated with ACS (OR 3.137; 95% CI, 1.918 to 5.131; p < 0.001, and OR 2.543; 95% CI, 1.428 to 4.527; p = 0.002, respectively). In conclusion, passive modes of transportation were the most frequently used to commute to and from school in young Ecuadorians. PA at school and total PA were positively associated with ACS. Thus, interventions at school setting could be an opportunity to improve PA levels and additionally ACS in youth from the central region of Ecuador.

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.

Background: Smoking, poor nutrition, excess alcohol consumption, and insufficient physical activity underlie most preventable causes of morbidity in the general population and may be associated with comorbidities and health outcomes in multiple sclerosis (MS). However, the frequency of co-occurrence of these risk factors in people with MS remains unclear. Methods: Sixty-nine individuals with MS completed self-report measures of smoking status, nutrition, alcohol use, physical activity levels, and sociodemographic and clinical characteristics. The data were analyzed using t tests and χ2 analyses. Results: Poor diet was the most common risk factor, with 85.5% of the sample not meeting dietary guidelines. Of participants with two risk factors, 90.3% were not meeting dietary and physical activity guidelines. Seventy-three percent of women were not meeting physical activity guidelines, compared with 38% of men (χ2 = 7.5, P &lt; .01). There were also differential rates by sex of the most commonly co-occurring risk factors: 65% of women reported the co-occurrence of insufficient physical activity and poor diet, compared with 38% of men (χ2 = 4.2, P = .05). Conclusions: These results indicate that 85.5% of the sample was not meeting nutrition guidelines, 90.3% of participants with two risk factors reported the co-occurrence of poor diet and insufficient levels of physical activity, and physical activity levels and the total number of risk factors varied across sex.

Sociodemographic Correlates

Background: Emerging evidence suggests that Indigenous children have higher physical activity levels that non-Indigenous children, yet little is known of the factors that influence these levels or how they may be optimized. This study examines correlates of achieving ≥1 hour/day of physical activity among Indigenous Australian children aged 8–13 years. Methods: Data were collected through parental self-report in the Longitudinal Study of Indigenous Children. Proportions of children achieving ≥1 hour/day physical activity, approximating the Australian aerobic physical activity recommendations, were calculated, and associations with sociodemographic, family composition, and movement-related factors were quantified using multiple logistic regression analyses. Results: Half of the 1233 children achieved ≥1 hour/day physical activity. Children from families with low parental education and unemployment, remote residence, low socioeconomic status, and without a father in the household were more likely to meet the recommendations. Achieving ≥1 hour/day of physical activity was also associated with low levels of playing electronic games and total screen time. Conclusions: Sociodemographic correlates of physical activity among Indigenous Australian children run counter to those typically found in non-Indigenous Australian children. Further longitudinal examination of the predictors of these associations would provide a greater understanding of Indigenous physical activity determinants, to inform strategies to facilitate participation.

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.

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.

Background:Approximately 17.4% of people in Mexico self-report physical activity levels below the World Health Organization’s guidelines and an average sedentary time of 16 hours per day.1 Low physical activity has been associated with noncommunicable disease risk factors and previous research suggests that urbanicity might be an important determinant of physical activity. The aim of this study was to measure urbanicity in Mexico and assess if it is associated with physical activity and sitting time.Methods:A sample of 2880 men and 4211 women aged 20 to 69 was taken from the 2012 Mexico National Health and Nutrition Survey and multivariable linear regression models were used to examine the association between physical activity, sitting time and urbanicity; adjusting for sex, education level, socioeconomic status and Body Mass Index. The urbanicity score and the 7 urbanicity subscores were estimated from the CENSUS 2010.Results:The subscores of demographic, economic activity, diversity and communication were negatively associated with physical activity. Sitting time was positively associated with the overall urbanicity, and the demographic and health subscores.Conclusions:There was evidence of associations between urbanicity and physical activity in Mexico.
