Background: Surveillance of domain-specific physical activity in the United States is lacking. Thus, the authors describe domain-specific moderate to vigorous physical activity (MVPA) in a nationwide sample of US adults. Methods: Participants from the AmeriSpeak panel (n = 2649; 20–75 y; 50% female) completed the Activities Completed Over Time in 24-Hours previous-day recall. The authors estimated average MVPA duration (in hours per day) overall and in major life domains by sex, age, race/ethnicity, and education. They also described the most commonly reported MVPAs and timing of MVPA during the day. Results: Across all life domains, participants reported an average of 2.5 hours per day in MVPA. Most MVPA was accumulated during work (50% of total, 1.2 h/d) and household activities (28%, 0.7 h/d) with less MVPA reported in leisure time (15%, 0.4 h/d). Time reported in MVPA varied by sex, and race/ethnicity (P < .05). Walking at work and for exercise, childcare, and walking for transportation were the most commonly reported domain-specific MVPAs. A greater proportion of MVPA took place in the morning (∼06:00 h) and evening (∼18:00 h). Conclusions: Work and household activities accounted for 78% of overall MVPA reported, while leisure-time MVPA accounted for only 15% of the total. Encouraging MVPA during leisure time and transportation remain important targets for promoting MVPA in US adults.

Background. Less than 50% of Latinas meet physical activity (PA) recommendations. Acculturation is a complex cultural phenomenon that may influence health behaviors, but associations between acculturation and Latinas’ activity and sedentary levels are unclear. Aim. To examine associations of acculturation with Latinas’ domain-specific and total PA as well as sedentary time. Method. We analyzed baseline data collected between 2011 and 2013 among 410 Latinas (18-65 years) from a PA promotion intervention in San Diego, CA ( Fe en Acción/ Faith in Action). Participants wore an accelerometer to assess moderate-to-vigorous PA (MVPA) and sedentary time and completed a survey assessing domain-specific PA, sociodemographics, and acculturation as measured by length of residence in the United States and the Bidimensional Acculturation Scale (BAS) for Hispanics. Higher acculturation was defined as longer residence in the United States or being either assimilated or bicultural as per scores on the Hispanic and Anglo domains of the BAS. Results. Based on weekly averages from the accelerometer, Latinas spent 103 minutes in MVPA and 76% of total activity in sedentary time. Only 32% met MVPA recommendations via self-reported leisure-time and transportation PA. Longer residence in the United States was inversely associated with reporting any transportation or occupational PA and meeting MVPA recommendations. Assimilated/bicultural Latinas had significantly less accelerometer-based total MVPA and higher sedentary time than their lower acculturated counterparts. Conclusions. Overall, higher acculturation, based on either measure, was related to less activity. Our findings suggest interventions tailored to the acculturation levels of Latinas are needed to help reduce disparities in Latinas’ PA and sedentary behaviors.

BACKGROUND WalkIT Arizona was a 2×2 factorial trial examining the effects of goal type (adaptive versus static) and reinforcement type (immediate versus delayed) to increase moderate to vigorous physical activity (MVPA) among insufficiently active adults. The 12-month intervention combined mobile health (mHealth) technology with behavioral strategies to test scalable population-health approaches to increasing MVPA. Self-reported physical activity provided domain-specific information to help contextualize the intervention effects. OBJECTIVE The aim of this study was to report on the secondary outcomes of self-reported walking for transportation and leisure over the course of the 12-month WalkIT intervention. METHODS A total of 512 participants aged 19 to 60 years (n=330 [64.5%] women; n=425 [83%] Caucasian/white, n=96 [18.8%] Hispanic/Latinx) were randomized into interventions based on type of goals and reinforcements. The International Physical Activity Questionnaire-long form assessed walking for transportation and leisure at baseline, and at 6 months and 12 months of the intervention. Negative binomial hurdle models were used to examine the effects of goal and reinforcement type on (1) odds of reporting any (versus no) walking/week and (2) total reported minutes of walking/week, adjusted for neighborhood walkability and socioeconomic status. Separate analyses were conducted for transportation and leisure walking, using complete cases and multiple imputation. RESULTS All intervention groups reported increased walking at 12 months relative to baseline. Effects of the intervention differed by domain: a significant three-way goal by reinforcement by time interaction was observed for total minutes of leisure walking/week, whereas time was the only significant factor that contributed to transportation walking. A sensitivity analysis indicated minimal differences between complete case analysis and multiple imputation. CONCLUSIONS This study is the first to report differential effects of adaptive versus static goals for self-reported walking by domain. Results support the premise that individual-level PA interventions are domain- and context-specific and may be helpful in guiding further intervention refinement.

Background. Work is reported as one of the main sources of psychological stress. Because of its role in the onset of burnout and impact on economic and health systems, work-related stress (WS) has become an issue of much concern. Among modifiable factors capable of reducing WS, two categories of physical activity (PA), namely leisure-time and moderate-to-vigorous physical activity (LTPA and MVPA), show promising evidence. Previous findings suggest that LTPA and MVPA allow adults to experience psychological detachment from job demands and restore their depleted resources at work. However, the optimal independent doses of LTPA and MVPA associated with a lower WS level has not yet been established. Methods. The aim of this study was therefore to address this gap using a cross-sectional, nationally representative sample of 4 200 Canadian workers. MVPA was measured through accelerometry and a self-reported assessment was conducted to collect data on WS and LTPA. Results. Generalized additive models indicated that one hour a day on average spent doing a LTPA of 8.5 METs-hour was associated with the highest benefits on WS (p < 0.001, Adjusted R2 = 0.04) while the optimal average daily dose of MVPA was around 90 minutes (p < 0.001, Adjusted R2 = 0.04). Noteworthy, first signs of WS reduction appear long before optimum is reached (e.g. 30 minutes of MVPA), stressing the relevance of merely doing an LTPA/MVPA regardless of the dose. Conclusion. Findings offer practical recommendations for public health policies on the optimal doses of MVPA/LTPA associated with decreased WS.

Regular moderate-vigorous physical activity (MVPA) reduces the risk of cardiovascular and other chronic diseases, among other important benefits at all life stages. It is hypothesized that physical activity may alter disease risk via epigenetic modifications, including potentially long-standing changes in DNA methylation as previous research has shown epigenetic changes following exercise interventions. Most existing reports examine global methylation or study acute exercise effects on DNA methylation. To our knowledge, there are no published epigenome-wide association studies (EWAS) of habitual MVPA. In this analysis, we tested associations between leisure time MVPA and genome-wide variation in CpG methylation, an epigenetic mark, in 2,601 African American participants (1,663 women; mean age 56.6 years) in the Atherosclerosis Risk in Communities (ARIC) study. The Illumina HM450K Bead Chip was used to measure methylation in 471,035 CpG sites in stored frozen leukocyte samples, from visit 2 (1990-1992) or 3 (1993-1995). Linear regression models tested the cross-sectional association of DNA methylation M-value with self-reported leisure time MVPA at the visit of sample collection, modeled as minutes of MVPA per week and by category based on the AHA guidelines for physical activity in adults (none, less than 150, or at least 150 minutes MVPA per week), adjusting for age, sex, body mass index, education, alcohol use in grams per week, smoking status, cancer status, white blood cell count, imputed cell-type proportions using the Houseman method, and batch effects with the top 30 HM450K built-in nonnegative control probe principal components. Three CpGs, cg08269485, cg20272155, and cg08966208, upstream of the cathepsin D encoding gene, CTSD, were observed to be significantly inversely associated (q<0.05, FDR) with MVPA minutes/week. This is a strongly imprinted genomic region (chr11p15.5) and the region has also been reported to include DNA methylation variants that changed in response to an exercise training intervention. Additionally, 163 CpGs that we identified in the literature to be associated with habitual MVPA were also tested using the same models. One CpG, cg07863043, upstream of the adenomatosis polyposis coli gene, APC, in the 5q22.2 genomic region, was observed to be significantly positively associated with achieving at least 150 minutes of MVPA per week compared to none (q=0.0001, FDR). APC encodes a tumor suppressor protein that is an antagonist of the Wnt signaling pathway, and is involved in carcinogenesis and embryonic development. Replication in other populations is ongoing to confirm these findings as well as to identify additional physical activity-related DNA methylation variants.

Background: A hallmark of clinically manifest heart failure (HF) is reduced levels of exercise tolerance and physical function. It is unclear, however, whether an association exists between poor physical function and future development of HF, particularly at older ages. Methods: Women (n=5327; mean±SD age = 79±7) with no history of HF completed the Short Physical Performance Battery (SPPB) to measure physical function. The SPPB consists of three timed tasks that assess standing balance (with 3 progressively difficult balance tests), strength (with 5 unassisted chair stands), and gait (with a 4m usual-pace walk), and is scored 0 (worst) to 12 (best). Four previously-defined categories were used: very low (SPPB 0-3; n=237); low (4-6; n=900), moderate (7-9; n=2139), and high (10-12; n=1767; referent group). Women were followed for up to 8 years for incident physician-adjudicated HF hospitalization. Cox proportional hazards regression models were adjusted for age, race-ethnicity, education, smoking, alcohol, diabetes, hypertension, COPD, osteoarthritis, depression, BMI, and accelerometer-measured moderate to vigorous physical activity (MVPA) and sedentary time. Results: The number of HF cases (crude rate/1000 person-years) across the above SPPB categories (very low to high) were 41 (33.5), 78 (15.5), 96 (7.8), and 41 (4.0). Covariate-adjusted HRs (95% CIs) were 3.39 (2.05-5.84), 2.20 (1.47-3.31), 1.74 (1.20-2.51) and 1.00 (ref), trend P<.001. After additional adjustment for MVPA and sedentary time, the fully-adjusted HRs (95% CIs) were 2.85 (1.71-4.75), 1.94 (1.29-2.93), 1.61 (1.10, 2.32) and 1.00 (ref), trend P<.001. When modeled continuously (per 3-unit decrement in SPPB score), fully-adjusted associations were consistent over stratum of age (<80: HR=1.72; ≥80: HR=1.56; interaction P=.05), race-ethnicity (white: HR=1.59; black: HR=1.59; Hispanic: HR=1.18; P=.57), and accelerometer-measured total physical activity (<5.6 hr/d: HR=1.54; ≥5.6 hr/d: HR=1.51; P=.81). Conclusions: A significant inverse association between SPPB score and HF incidence was observed in ambulatory older women, independent of age, physical activity levels, and other HF predictors. Physical function is a modifiable factor that may be important for HF prevention in later life.

Objective To assess physical performance (PP) and physical activity (PA) among older adults visiting primary healthcare centres (PHCCs) in Riyadh. Methods In this cross-sectional study, men and women (n = 74) aged ≥60 years were recruited from five PHCCs across Riyadh, Saudi Arabia, between 19 February and 6 August 2017. The Timed Up & Go test was used to assess PP. Self-reported PA was assessed using the Physical Activity Scale for the Elderly. Means and standard deviations were used to describe PP and PA scores across genders. A two-tailed independent samples t-test was used to estimate mean differences (MD) and 95% confidence intervals (CI) between genders. Results Men scored significantly lower than women on PP (MD: 2.11, 95% CI: 0.59 to 3.64) and PA (MD: −46.1, 95% CI: −80.96 to −11.25). Significant gender differences were observed for leisure time activities (MD: 17.35, 95% CI: 3.29 to 31.40), light household activities (MD: –10.86, 95% CI: –16.19 to –5.53) and heavy household activities (MD: –6.48, 95% CI: –11.73 to –1.23). Conclusions Men show significantly lower PP and PA than women. There are gender differences in leisure time activities and in light and heavy household activities.

ObjectivesTo investigate the impact of first eye and second eye cataract surgery on the level of physical activity undertaken by older adults with bilateral cataract.DesignProspective cohort study.SettingThree public ophthalmology clinics in Western Australia.ParticipantsFifty-five older adults with bilateral cataract aged 55+ years, awaiting first eye cataract surgery.Outcome measuresThe primary outcome measure was participation in moderate leisure-time physical activity. The secondary outcomes were participation in walking, gardening and vigorous leisure-time physical activity. Participants completed a researcher-administered questionnaire, containing the Active Australia Survey and visual tests before first eye cataract surgery, after first eye surgery and after second eye surgery. A Generalised Estimating Equation linear regression model was undertaken to analyse the change in moderate leisure-time physical activity participation before first eye surgery, after first eye surgery and after second eye surgery, after accounting for relevant confounders.ResultsParticipants spent significantly less time per week (20 min) on moderate leisure-time physical activity before first eye cataract surgery compared with after first eye surgery (p=0.04) after accounting for confounders. After second eye cataract surgery, participants spent significantly more time per week (32 min) on moderate physical activity compared with after first eye surgery (p=0.02). There were no significant changes in walking, gardening and vigorous physical activity throughout the cataract surgery process.ConclusionFirst and second eye cataract surgery each independently increased participation in moderate leisure-time physical activity. This provides a rationale for timely first and second eye cataract surgery for bilateral cataract patients, even when they have relatively good vision.
