Abstract 4138564: Fitbit-Measured Physical Activity Is Inversely Associated With Incident Atrial Fibrillation Among All Of Us Participants

Background: Studies show that moderate to vigorous physical activity (MVPA) reduces atrial fibrillation (AF) risk. However, these studies used subjective questionnaires or short-term (<1 week) accelerometry assessments. Objective: This study investigated the link between MVPA levels and AF incidence using long-term (1-year) accelerometry data from the NIH All of Us Fitbit database. Methods: The study included All of Us participants who agreed to share electronic health record (EHR) and Fitbit data between January 1, 2016 to July 1, 2022. Among participants without an existing diagnosis of AF, the average weekly minutes of MVPA over the first year of Fitbit use was computed. Incident AF events were identified using validated ICD-10 codes in a five-year follow-up period. The risk of incident AF was evaluated using Cox proportional hazards regression models, for both MVPA as a continuous and a categorical variable (<30, 30-150,151-300, and >300 minutes MVPA per week; aligned with WHO guidelines). Covariates included age, sex, race/ethnicity, BMI, smoking status, and diagnoses of hypertension and diabetes. In a subset of participants with whole genome data, we evaluated if the association between MVPA and AF incidence varied by a participant’s AF genetic risk score (GRS) Results: 6086 participants (mean age 50 years, 71% female, 83% White) had EHR and at least 1 year of Fitbit data. Over the 1-year MVPA assessment period, participants had 41±12 weeks of complete data and a median 202 [241] minutes of MVPA per week. 55 participants (0.9%) experienced incident AF in the five-year follow-up period. In adjusted analysis, every additional hour of MVPA was associated with an 11% reduced risk of AF (HR = 0.89 [0.81,0.98], p = 0.02). There was a step-wise reduction in risk of AF by MVPA category with <30 min/week as the reference: 30-150 (HR = 0.62 [0.24,1.6], p = 0.31), 151-300 (HR = 0.40 [0.15,1.07], p = 0.07), and >300 (HR = 0.35 [0.13,0.95], p = 0.04) ( Figure 1 ). These associations also held after adjusting for GRS. Conclusion: Higher amounts of objectively measured MVPA were inversely associated with risk of incident AF, independent of clinical and genetic risk factors.

Examining real-time physical activity in adolescents using the Multi-Process Action Control Model: An ecological momentary assessment study

The purpose of this study was to examine real-time associations between reflective (i.e., state motivation), regulatory (i.e., self-control), and reflexive (i.e., habit) constructs from the Multi-Process Action Control (M-PAC) model and real-time moderate-to-vigorous physical activity (MVPA) behaviour among adolescents using ecological momentary assessments. One hundred and ninety adolescents (Mage = 15.76 ± .47 years; n = 101 males) wore an accelerometer for seven consecutive days and responded to digital survey prompts up to four times daily during the after-school periods. MVPA in the 60-minute time window following each survey prompt was recorded. Multilevel mixed-effects linear and logistic models were computed with disaggregated between- and within-person effects to analyze the data. Results from both linear and logistic multilevel models revealed adolescents with higher state motivation in general and experiencing higher state motivation than one’s typical levels were associated with engaging in more MVPA and higher likelihood of engaging in ≥10 minutes of MVPA. Engaging in activities less consistent with habitual behaviours were associated with more MVPA and higher likelihood of engaging in ≥10 minutes of MVPA. By contrast, self-control was not associated with MVPA. Results from this study extend previous work demonstrating the importance of conscious and non-conscious processes on MVPA behaviour by examining associations in real-time using intensive longitudinal methods. Collectively, this study provides partial support for use of the M-PAC framework to explain acute MVPA among adolescents in real-time and natural contexts.

Motivational and emotional correlates of physical activity and sedentary behavior after cardiac rehabilitation: an observational study

BackgroundThe present study assessed physical activity (PA) and sedentary behavior (SB) levels and their motivational and emotional health-related correlates, in outpatients following a cardiovascular rehabilitation (CR) program, and compared these variables with those of a healthy control group.MethodsThe study included 119 participants: 68 CR outpatients (Mage 57.76 ± 10.76; 86.76% males) and 51 control participants matched on age (Mage 57.35 ± 6.33 years; 45.10% males). PA and SB were assessed using accelerometers during the first week post-discharge for outpatients and during a typical week for controls. Motivational (i.e., perceived capabilities, affective and instrumental attitudes, intention, approach-avoidance tendencies) and emotional health-related variables (i.e., anxiety, depressive symptoms, fatigue, pain intensity) were measured using validated scales. PA and SB data from 17 outpatients and 42 controls were valid for analysis, resulting in a final sample of 59 participants.ResultsCR outpatients engaged an average of 60.21 (± 34.79) min of moderate-to-vigorous PA (MVPA), and 548.69 (± 58.64) min of SB per day, with 18 more minutes of MVPA per day than controls (p = .038). Univariate and multivariate regressions indicated that positive affective attitudes were associated with higher MVPA (b = 10.32, R2 = 0.07, p = .029), and that males spent more time in SB than females (b = 40.54, R2 = 0.09, p = .045). Univariate and multivariate logistic regressions showed that meeting the World Health Organization’s weekly guidelines for MVPA was associated with higher perceived capabilities toward PA and more positive affective attitudes (OR = 1.17, p = .030; OR = 1.26, p < .001, respectively). Interaction tests showed no significant differences in these results between outpatients and controls.ConclusionThe study highlights an association between higher perceived capabilities and positive affective attitudes toward PA with higher PA levels after outpatient CR. While these findings suggest that enhancing these motivational variables may be beneficial for increasing PA levels after CR, longitudinal and experimental studies are needed to further establish their role.

Adult Sports Participation and Physical Activity: How About Curling?

Despite its well-documented physical and psychosocial benefits, sport remains the least engaged form of physical activity (PA) among adults. Many adults may lack the skills needed to play or continue to play sports and aging adults are more likely to avoid participation for fear of poor performance or injury. A sport that shows great promise for adults seeking new sports participation outlets is curling. Curling is a team sport comprised of four interchangeable positions working collectively to deliver granite stones across a sheet of ice in an effort to outscore the opponent team. While it seems reasonable that walking on ice, “throwing” a 44 lb granite stone across a sheet of ice, and periodically sweeping while walking on ice over a two-hour period would generate at least a moderate amount of physical activity, research to date is quite limited. Therefore, the purpose of this study was to objectively measure the amount and intensity of PA achieved by average recreational curling participants during a typical curling match. Methods Members of a curling club in NC were asked to wear Actigraph Accelerometers (model GT3X) while they participated in their regularly scheduled curling match. All participants had at least one year of curling experience. Curling matches lasted between 90 and 120 minutes. Participants were asked to indicate their age, gender, and curling position during the match (lead, second, vice, skip) which were matched with accelerometer data. Results Overall, 110 participants (37 female, 73 male, avg. age 50 yrs) spent most of their curling time in light or moderate-intensity activity (18.1% Sedentary; 49.5% light; 32.4% moderate; .03% vigorous). In terms of minutes, the average participant spent 35.9 minutes engaged in Moderate-to-Vigorous PA (MVPA) per curling experience. This represents 23.9% of the weekly 150min of MVPA suggested by the CDC. The second position had the highest percentage of moderate activity level and a small percentage of vigorous activity. No other position reached a vigorous level. The skip position had the highest amount of sedentary activity as well as light activity. Females had a higher level of moderate activity in comparison to males. However, males reached a small amount of vigorous activity. The age group of 18 - 36 had the highest amount of moderate activity and the lowest amount of sedentary activity. This age group reached an average of 41.0 minutes of MVPA per curling experience. The age group of &gt; 58 had the highest amount of sedentary activity and the lowest amount of moderate activity. Conclusions Curling may be a good sports participation option for adults looking for alternatives to meet recommended weekly amounts of MVPA. Participants should consider playing in one of the first three positions to maximize the amount and intensity of PA achieved while playing. Furthermore, since curling also requires balance, coordination, muscular strength, multitasking, strategic reasoning, and can cater to most physical challenges without compromising the integrity of the game, it may be an ideal sport to promote for adults of all ages and sport abilities. Implications for Practice and Policy Findings should be used to inform strategies for promoting curling as an opportunity for team sport involvement that has the added value of contributing to daily physical activity. However, , access and opportunities to play, especially for underserved populations, are limited. Given that most curling clubs in America are private and require a membership to play. Partnership arrangements between existing clubs and public parks and recreation departments could increase both access and opportunities to play.

The Effects of the LiiNK Intervention on Physical Activity and Obesity Rates among Children

Background: Obesity and inactivity among children are at an all-time high and have been steadily increasing in prevalence over the last thirty years. The school environment provides the ideal setting for reaching a large number of children across diverse populations in order to reverse these trends. However, there are many inconsistent results yielded by school-based physical activity interventions due to implementation length, time for activities, and the use of structured physical activities. The LiiNK Project® is a whole-child intervention addressing these gaps by providing children 45–60 min of recess (unstructured, outdoor play) in their schools daily, while the control children are allowed to engage in recess for 30 min daily. The purpose of this study was to compare the physical activity intensity and obesity rates of third- and fourth-grade children participating in the LiiNK intervention, which provides 60 min of recess for third graders and 45 min for fourth graders, to those in a control group allowed 30 min of daily recess. Methods: The children were 8–10 years old (M = 9.2; 52% females and 48% males). The intervention children comprised 90 third graders and 100 fourth graders, and the control children comprised 101 third graders and 92 fourth graders. Physical activity levels were monitored using accelerometers to assess sedentary, light, and moderate-to-vigorous physical activity (MVPA). Obesity rates were evaluated using bio-electrical impedance analysis (BIA), in which body fat percentage is calculated based on normative values using age and sex in the equation. Results: The third-grade intervention children engaged in 13 more MVPA minutes and took 900 more steps daily than their control counterparts, and also presented a greater proportion of overweight children transitioning to a healthy weight status from the fall to the spring semester. Conversely, the fourth-grade control children increased their activity by 500 steps and 15 more MVPA minutes daily. Despite this, the intervention children overall demonstrated a reduction in body fat percentage, while the control children demonstrated an increase in body fat percentage. Conclusions: Ultimately, 60 min of unstructured, outdoor play in schools provides children the best opportunity to engage in MVPA, which may positively impact body fat percentages, offering a potential strategy for combatting childhood obesity in school settings.

Recommended moderate to vigorous physical activity levels for people in the chronic phase of stroke can be achieved in outpatient physiotherapy: a multicentre observational study

ABSTRACT Background Rehabilitation in the chronic phase of stroke should include 20 minutes of moderate to vigorous physical activity (MVPA). However, the level of compliance with MVPA guidelines in outpatient physiotherapy is unknown. Objectives To investigate (1) whether people in the chronic phase of stroke perform the recommended 20 minutes of MVPA during outpatient physiotherapy sessions in France, (2) whether the person’s clinical characteristics influence MVPA time and (3) which interventions contribute to achievement of recommended MVPA time. Methods This was a multicentre, cross-sectional observational study of routine outpatient physiotherapy sessions in France in people in the chronic phase of stroke. The main measures included MVPA time (determined using a heart rate monitor), clinical tests and types of physiotherapy interventions (recorded by external investigator during 2 sessions for each participant). Results 84 people in the chronic phase of stroke and 152 outpatient physiotherapy sessions in 29 outpatient clinics were included (2021–2022). Median (interquartile range) MVPA time was 25 (7–45) minutes across all sessions. Fifty-nine percent of the sessions fulfilled MVPA guidelines. Among clinical tests, only the Mini-Mental Scale Examination was significantly associated with MVPA time. Endurance, balance, and functional lower limb training were associated with the achievement of MVPA guidelines. Conclusion Outpatient physiotherapy sessions have the potential to meet the MVPA guidelines. Further research is needed to understand the variability of compliance with MVPA guidelines and to develop strategies to increase the integration of MVPA into outpatient physiotherapy sessions.

Changes in Accelerometer-Measured Physical Activity and Sedentary Time Across Retirement Transition as a Predictor of Self-Rated Health.

Retirement transition has been shown to associate with changes in physical activity (PA) and self-rated health (SRH), but their interrelationship is less studied. The aim was to investigate changes in accelerometer-measured total PA, moderate to vigorous PA (MVPA), and sedentary time across retirement transition as a predictor of SRH. Data from the Swedish Retirement Study and the Finnish Retirement and Aging study were harmonized and pooled. Data from 3 waves (about 12mo apart) were included: 1 preretirement (wave 1) and 2 postretirement follow-ups (wave 2-3). A totally of 245 participants (27% men) were included. Thigh-worn accelerometers were used to collect data for PA variables (wave 1-2), and SRH was obtained from the questionnaire (wave 1-3). Between wave 1 and 2, total PA decreased with 11 (CI, -22 to -1)minutes per day, MVPA was stable (0 [CI, -3 to 3]min), and sedentary time decreased nonsignificantly with 9 (CI, -20 to 1)minutes. SRH changed between all 3 waves (all P < .001). At preretirement, 10 more minutes of MVPA was associated with greater odds of better SRH when adjusting for accelerometer wear-time, cohort, sex, age, and occupational status (odds ratio: 1.11 [95% CI, 1.02-1.22]). This association was no longer statistically significant when additionally adjusting for marital status, body mass index, and smoking. No significant associations were observed between changes in the PA variables during retirement transition and SRH at postretirement follow-ups. This study showed a cross-sectional association between MVPA and greater odds of reporting better SRH before retirement. No longitudinal associations were observed between changes in the PA variables from before to after retirement and later changes in SRH.

The Influence of Psychological Factors on Physical Activity in Individuals With Patellofemoral Pain.

Patellofemoral pain (PFP) is a prevalent chronic condition characterized by retropatellar or peripatellar pain exacerbated by various knee flexion-based activities. Previous research has highlighted the impact of psychological constructs on pain and function in chronic musculoskeletal pain conditions, yet their influence on physical activity in PFP cohorts remains unexplored. We aimed to evaluate whether pain self-efficacy and pain catastrophizing predict variations in steps per day and moderate to vigorous physical activity (MVPA) among individuals with PFP. Cross-sectional observational study. Thirty-nine participants (11 males) with PFP were included. Dependent variables were steps per day and minutes of MVPA. Independent variables were pain self-efficacy and pain catastrophizing, measured by the pain self-efficacy questionnaire and the pain catastrophizing scale. Participants were given an ActiGraph wGT3X-BT for 7days to assess physical activity. Correlations were assessed between psychological measures and physical activity, and a simple linear regression was performed on psychological variables that correlated with physical activity. Alpha was set a priori at P < .05. Pain self-efficacy scores displayed a moderate association with steps per day (rho = .45, P = .004) and a weak association with MVPA (rho = .38, P = .014). Pain catastrophizing scores exhibited no significant associations with physical activity (P < .05). Regression models affirmed pain self-efficacy scores as significant predictors of both steps per day (F1,37 = 10.30, P = .002) and MVPA (F1,37= 8.98, P = .004). Psychological measures continue to demonstrate value to clinicians treating PFP. Pain self-efficacy scores were moderately associated with steps per day and weakly associated with MVPA, explaining nearly a fifth of the variation in physical activity. Clinicians should prioritize the assessment of pain self-efficacy when treating individuals with PFP, potentially employing psychological interventions to improve physical activity in the PFP population.

Inequality in Children’s Physical Activity Across Time-Segmented Youth Sport Practice

ABSTRACT Purpose: Youth sport (YS) is a community system for promoting children’s physical activity (PA). Studies have examined mean PA during YS practices, but few have examined inequalities in the distribution of PA among children during practice time. This study examined PA inequality in time-segmented YS practices and differences in inequality by time segment characteristics. Methods: Children’s PA and YS practices were examined using accelerometer and video observation data from a sample of YS teams (n = 36 teams, n = 101 practices) for third- through sixth-grade children (n = 392), approximately eight to 12 years old, in two rural U.S. communities. Practices were time-segmented into smaller units (episodes; n = 991). Episodes were assigned codes for purpose (e.g. warm-up), member arrangement (e.g. whole group), and setting demand (i.e. fosters participation, creates exclusion). Group accelerometer data were paired with episodes, and the Gini coefficient quantified inequality in activity counts and minutes of moderate-to-vigorous PA (MVPA). Beta generalized estimating equations examined the influence of episode structure on PA inequality. Results: Warm-up (Gini = 0.22), fitness (Gini = 0.24), and sport skill (Gini = 0.24) episodes had significantly lower inequality (p < .05) in activity counts than other purpose types. Management (Gini = 0.32) and strategy (Gini = 0.40) episodes had significantly greater inequality (p < .05) in MVPA minutes than other purpose types. Episodes fostering participation (Gini = 0.32) had significantly lower activity count inequality (p < .05) than episodes creating exclusion (Gini = 0.35). Conclusion: PA inequality among children during YS varied by practice structure. Metrics such as the Gini coefficient can illuminate inequalities in PA and may be useful for guiding efforts to improve population PA in children.

Impact of lifestyle moderate-to-vigorous physical activity timing on glycemic control in sedentary adults with overweight/obesity and metabolic impairments.

Moderate-to-vigorous physical activity (MVPA) improves glucose levels; however, whether its timing affects daily glycemic control remains unclear. This study aims to investigate the impact of lifestyle MVPA timing on daily glycemic control in sedentary adults with overweight/obesity and metabolic impairments. A total of 186 adults (50% women; age, 46.8 [SD 6.2] years) with overweight/obesity (BMI, 32.9 [SD 3.5] kg/m2) and at least one metabolic impairment participated in this cross-sectional study. MVPA and glucose patterns were simultaneously monitored over a 14-day period using a triaxial accelerometer worn on the nondominant wrist and a continuous glucose-monitoring device, respectively. Each day was classified as "inactive" if no MVPA was accumulated; as "morning," "afternoon," or "evening" if >50% of the MVPA minutes for that day were accumulated between 0600 and 1200, 1200 and 1800, or 1800 and 0000 hours, respectively; or as "mixed" if none of the defined time windows accounted for >50% of the MVPA for that day. Accumulating >50% of total MVPA during the evening was associated with lower 24-h(mean difference [95% CI], -1.26 mg/dL [95% CI: -2.2 to -0.4]), diurnal (-1.10 mg/dL [95% CI: -2.0 to -0.2]), and nocturnal mean glucose levels (-2.16 mg/dL [95% CI: -3.5 to -0.8]) compared with being inactive. This association was stronger in those participants with impaired glucose regulation. The pattern of these associations was similar in both men and women. These findings suggest that timing of lifestyle MVPA is significant. Specifically, accumulating more MVPA during the evening appears to have a beneficial effect on glucose homeostasis in sedentary adults with overweight/obesity and metabolic impairments.

Association Between Physical Activity and Risk of Developing Type 2 Diabetes Among Older Adults in Nigeria: A Cross-Sectional Study

Abstract Context: Type 2 diabetes is a growing public health problem worldwide, causing a high number of premature mortalities, especially among older adults. Aim: To understand the association between moderate-to-vigorous physical activity (MVPA) and the risk of developing type 2 diabetes among older adults. Materials and Methods: A multistage probability sampling technique was used to recruit 400 older adults (age =68.8 ± 6.5 years; male =68.8%) from their households in Maiduguri. Weekly minutes of MVPA were evaluated using the Hausa International Physical Activity Questionnaire-Short form, and the risk of developing type 2 diabetes was measured using the validated Finnish Diabetes Risk Score Questionnaire. Adjusted linear regression analysis explores associations between MVPA and the risk of developing type 2 diabetes. Results: It was found that 18.4% of the participants were obese, and 14.5% had a high and very high risk of developing type 2 diabetes. After adjusting for confounding variables (age, gender, BMI, and level of education), MVPA was associated with the risk of developing type 2 diabetes (β = −1.75, P = 0.01). There was significant interaction with gender, with protective effect found only in male older adults (β = −2.59, P = 0.01) and not among female Older adults (β =0.54, P = 0.61). Conclusions: Our data suggest that higher levels of MVPA are associated with a lower risk of developing future type 2 diabetes in a population of older adults in Nigeria, especially among men. A future longitudinal study, with a diverse large sample size and more objective measures, is needed to further determine the generalization of the findings observed.

Differential relationships between physical activity and pain phenotypes in individuals with spinal cord injury

Background Chronic pain affects 70% of individuals with spinal cord injury (SCI) and leads to declines in health and quality of life. Neuropathic and nociceptive pain are phenotypes derived from different mechanisms that contribute to pain perception. The objective of this research was to investigate differential pain responses to moderate-to-vigorous physical activity (MVPA) in two chronic pain phenotypes: neuropathic and nociceptive pain. Methods Community-based physical activity levels were collected for one week in 17 individuals with SCI using a wrist-worn accelerometer, and daily pain ratings were assessed and categorized by phenotype. Physical activity levels were summarized to calculate minutes of MVPA. Correlational analyses were conducted to compare relationships between pain intensity and MVPA across individual participants and between pain phenotype groups. Results The neuropathic pain group revealed significant negative correlation between MVPA and pain intensity. In the nociceptive pain group, there was no significant correlation between MVPA and pain intensity. Further analysis revealed two subgroups of positive (N = 4) and negative (N = 3) correlations between MVPA and pain intensity. Pain location differed between the subgroups of nociceptive pain. Individuals with negative correlation experienced neck and upper back pain, whereas individuals with positive correlation experienced unilateral upper extremity pain. Conclusion Differential relationships exist between pain phenotypes and MVPA in individuals with SCI. Pain location differed between the subgroups of nociceptive pain, which we presume may indicate the presence of nociplastic pain in some individuals. These results may contribute to the advancement of personalized pain management by targeting non-pharmacological interventions for specific pain phenotypes.

Should organized sport characteristics be considered as a strategy for meeting physical activity guidelines in children?

A clearer understanding of the relationships between specific sport context with overall physical activity (PA) and sedentary time (ST) may contribute to the development of more accurate preventive strategies to increase children's engagement in PA. This study aimed to examine how different organized sports contributed to children's daily PA and ST. PA was measured for seven days via accelerometers, in 410 children aged 6-10 years (49.8% boys). Of those, 332 (53.0% boys) were engaged in an organized sport and were further considered for statistical analyses. Parents reported children's sport participation (e.g. which sport, number of times per week, duration). The sports were classified into: indoor vs. outdoor; individuals vs. team; combat vs. individual aesthetic vs. racing vs. invasion. Children's height and weight were objectively collected. Multiple one-way analyses of covariance were used to examine the effects of sport characteristics on PA and ST. A linear regression, adjusted for children's sex, age, body mass index and father's educational level, determined the relationship between being involved in multiple PA and sedentary behaviours with Moderate to Vigorous PA (MVPA) levels. Although engaged in an organized sport, only 30% of the children achieved the PA recommendations. Sport (compared with active commute and active play) was the best contributor to daily MVPA. Outdoor sports (vs. indoor) contributed the most to vigorous PA (VPA) and MVPA. Team sports (vs. individual) were significantly associated with lower ST. Children in combat sports accumulated more VPA and MVPA, while those in racing sports showed a higher ST. Sport participation alone does not guarantee children will reach the PA guidelines, and the type of sport can influence children's PA levels. Gender-stereotypes in sports may prevent girls from achieving their 60 minutes of MVPA daily.

Abstract 2246: The impact of a waitlist control group on physical activity level in the activity after cancer treatment exercise oncology randomized pilot study

Abstract Background: In randomized clinical trials, control conditions such as blinding are essential for mitigating threats to validity. In exercise oncology trials, researchers are unable to blind participants to randomization, which may confer unintended consequences (i.e., crossover or dropout) that may threaten validity. Despite prior suggestions that a waitlist control is optimal for lessening these consequences, to date there is little agreement concerning control conditions in exercise oncology. Further, the use of a waitlist control is complicated by concerns regarding the ethical implications of instructing participants to delay healthy behavior change. Herein, we leveraged data from the Activity after Cancer Treatment (ACT) study to evaluate the impact of randomization to a waitlist control group on objectively assessed physical activity (PA) levels in breast cancer (BC) survivors. Methods: The ACT Study (PI: Ambrosone) was a 12-week, four-arm pilot study at Roswell Park Comprehensive Cancer Center. Participants included 37 BC survivors who were randomized to either a waitlist control group (n=10), or one of three exercise interventions of varying intensities including home-based walking (n=9), home-based Zumba (n=9), or a supervised high-intensity interval training treadmill protocol (n=9) delivered by study personnel at Roswell Park Comprehensive Cancer Center. The waitlist group was asked to maintain their usual PA during the 12-week intervention. All participants received weekly phone calls to optimize engagement and ensure Fitbit data were properly synced. For the current analysis, the primary analytic exposure was randomization assignment (control or active intervention); the analytic outcomes included steps/day, moderate-to-vigorous PA (MVPA) minutes/week and total active minutes/week as measured by the Fitbit Charge 2. ANOVA was used to assess mean group differences in steps and active minutes. Results: At study conclusion, the control group accumulated significantly fewer steps/day [6,087 (±1,353)] than the active intervention groups [8,729 (±2,585), p=0.0003]. The control group also accumulated significantly fewer MVPA minutes/week [146.2 (±114.9) vs. 264.1 (±192.3), p=0.045] and total active minutes/week [1,478 (±291.0) vs. 1,976.8 (±658.6), p=0.003] in comparison to the active intervention groups, respectively. Conclusions: BC survivors randomized to active intervention accumulated significantly more steps, MVPA and total active minutes than the waitlist group. Although the waitlist was effective for minimizing PA relative to the active arms, waitlisted participants exceeded the national step average of 4800 steps/day by 1200 steps and nearly met the minimum PA recommendation of 150 minutes of MVPA/week, potentially assuaging ethical or public health concerns regarding the delay of health-seeking behavior.

Abstract 2154: Actívatexto:Feasibility and acceptability of a mobile intervention that promotes smoking cessation and physical activity among Latinos

Abstract The purpose of this study was to assess the feasibility and acceptability of a mobile intervention that promotes smoking cessation and physical activity among Latinos. Twenty Latino adults who smoked and did not meet recommended levels of physical activity were recruited using community-based recruitment strategies. Participants received Actívatexto, a theory-based, culturally accommodated, 12-week text messaging intervention (available in English and Spanish) that promotes both smoking cessation and physical activity. Actívatexto integrates four components: 1) a text messaging program that promotes both smoking cessation and physical activity, 2) a wearable device to monitor physical activity, 3) an online dashboard where the research team manages participants’ incoming and outgoing data from both the text messaging program and wearable devices, and 4) smoking cessation pharmacotherapy (i.e., nicotine replacement therapies). We assessed self-reported 7-day point prevalence smoking abstinence (not smoking any cigarettes in the past seven days) at Month 3, weekly minutes of moderate to vigorous physical activity (MVPA), pharmacotherapy adherence, self-efficacy, and satisfaction. At baseline, participants’ mean age was 47.3 years old (SD 16.0), 55% of participants were female, 80% had completed high school or lower educational level, and 60% indicated that Spanish was their language of preference. Most participants (75%) smoked 1-10 cigarettes daily, 35% smoked their first cigarette within five minutes after waking up, and 60% used menthol cigarettes. At Month 3, 14 participants (70%) self-reported 7-day point prevalence smoking abstinence (90% follow-up rate). Fitbit-assessed mean minutes of MVPA per week increased from 113 (SD 127; range 0-399) at Week 1 to 177 (SD 163; range 0-513) at Month 3, although the difference was not statistically significant (p=0.15). Sixteen participants (88.9%, 16/18) reported NRT use in the past 90 days. Mean scores of self-efficacy for smoking cessation increased from 31.2 (SD 10.6) at baseline to 47.8 (SD 13.0) at Month 3 (p&amp;lt;0.01). Mean scores of self-efficacy for physical activity increased from 12.3 (SD 3.9) at baseline to 14.6 (SD 4.4) at Month 3 (p=0.2). Most participants reported being satisfied or extremely satisfied with the intervention (88.9%, 16/18). In conclusion, Actívatexto resulted in a noteworthy cessation rate at Month 3 (70%), increased mean minutes of MVPA per week, produced high use of NRT, increased self-efficacy for smoking cessation and physical activity, and was well received by participants.

Perceived barriers and facilitators of childcare providers’ physical activity: A mixed-methods study

Background: Childcare providers’ work demands have been associated with high rates of stress and health conditions. Physical activity (PA) may help to alleviate some of these issues, yet few studies have explored this topic. The purpose of the study was to assess childcare providers’ PA levels and to explore their perceived barriers and facilitators to PA. Methods: This was a mixed-methods concurrent triangulation study with childcare providers ( n = 27) from both family childcare homes and childcare centres from urban ( n = 14) and rural ( n = 13) areas. Accelerometers and the Global Physical Activity Questionnaire (GPAQ) measured the amount of PA (leisure, transport-related, occupational), and a semi-structured interview explored barriers and facilitators to PA. Descriptive statistics were calculated for PA data. Qualitative data were analysed using thematic content analysis. Results: For accelerometer data, on average per day, childcare providers accumulated 199.5 ± 62.5 minutes of light activity, 125.9 ± 68.1 minutes of moderate to vigorous PA (MVPA) and 666.3 ± 23.7 minutes of sedentary time. For GPAQ data, childcare providers reported 114.5 ± 48.4 minutes/day of MVPA and 295.6 ± 141.4 minutes/day of sedentary time. Common barriers included time constraints and health issues, while common facilitators included knowledge of PA health benefits and family/peer support. Conclusion: The study suggests an estimated 92% of childcare providers met the US national PA guidelines of 150 minutes of MVPA per week. However, they exhibited prolonged periods of sedentary behaviour (~11 hours). Programmes and interventions could address barriers to PA such as providing short movement breaks to decrease sedentary time and improve childcare providers’ health.

A natural experiment to assess recess frequency on children’s physical activity in Arizona (U.S.) elementary schools

BackgroundIn the United States, the number of state policies mandating recess in schools has rapidly increased over the past decade; however, few policies specify recess frequency. Informed by an ecological model of physical activity (PA) policy, this study examined and compared total amounts and intensity of PA expended during recess among children attending schools in compliance with Arizona recess policy ARS§ 15–118 mandating 2 + daily recess periods versus not.MethodsPA during recess was measured among grade three children (ages 8–10) in four randomly selected elementary schools (two complying averaging 30 daily recess minutes; two non-complying averaging 15 daily recess minutes) in Maricopa County, Arizona. Group-level PA was assessed by direct observation using the System for Observing Play and Leisure (137 observations). A subset of students (N = 134) from all schools wore ActiGraph GT3X + devices during recess to measure individual PA. General linear mixed effects models were used to analyze the impact of recess frequency on group and individual PA during recess.ResultsStudents attending complying schools spent significantly greater proportions of time in moderate-to-vigorous PA (MVPA) based on direct observation (5%) and accelerometry (15%) and less time being sedentary based on accelerometry (14%) during recess. Across the school day, this would equate to 5.1 more MVPA minutes based on systematic direct observation and 9.5 more MVPA minutes based on accelerometry, and 4.1 less minutes being sedentary based on accelerometry if students received two daily 15-minute recess periods compared to one.ConclusionsStudents attending elementary schools implementing 2 + recesses, in accordance with state policy, demonstrated greater MVPA and less sedentary time, providing preliminary evidence that recess frequency is associated with greater PA intensity among children during recess. Schools that adhere to state-level PA policies may provide a more supportive environment for PA, resulting in increased movement among students. Specifying recess frequency should be considered in statewide recess policy.

Lower cardiac rehabilitation enrolment occurs in acute coronary syndrome patients who report low levels of physical activity at four weeks post-event: A prospective observational study using physical activity tracker data

BackgroundPhysical activity (PA) and cardiac rehabilitation (CR) attendance are important for recovery and prognosis following acute coronary syndrome (ACS). However, PA patterns early post-ACS are not well known. ObjectivesInvestigate the level of PA at 4-weeks post-ACS and any potential associations with CR enrolment. MethodsWe recruited patients admitted for ACS from cardiac wards and clinics at two hospital sites in Sydney, Australia. PA data were collected using wearable activity trackers worn at 4-weeks post-ACS, and CR enrolment was self-reported. ResultsParticipants (n = 61) were aged 66.7 ± 10.3 years, 74 % male, 61 % were married or partnered, and 33 % were diagnosed with ST-elevation myocardial infarction. Patients engaged in 7514±3355 steps per day and 44.6 ± 37.5 min of moderate-to-vigorous physical activity (MVPA). Patients who enrolled in CR exhibited higher daily step counts (p = 0.044), MVPA minutes (p = 0.001), and were more likely to meet PA guidelines. ACS patients who engaged in higher levels of MVPA were more likely to enrol in CR (odds ratio [OR] 1.46; 95 % confidence interval [CI] 1.08, 1.98). CR enrolment was also positively associated with being married or in an intimate partnership (OR 9.93; 95 % CI 1.83, 53.85) and absence of depressive symptoms (OR 11.86; 95 % CI 1.91, 73.74). ConclusionLower CR enrolment rates were observed among less physically active patients at 4-weeks post-ACS. However, each 10 min increment in MVPA increased the odds of CR enrolment by 46 %. Future research should explore strategies to target this inactive and high-risk group, given the potential for a large prognostic gain with CR participation.

The availability between recreational facilities and physical activity of US adolescents

Determining the locations where adolescents tend to accumulate greater amounts of physical activity may assist policymakers to address the built environment design and promote PA. This study evaluated the association between the availability of recreational facilities and average minutes of moderate to vigorous physical activity (MVPA) per day of US adolescents in 2017 (n = 1,437). Data for this cross-sectional study were obtained from the 2017 Family Life, Activity, Sun, Health, and Eating study, an internet-based study collecting information on diet and PA of parent and adolescent dyads. Adolescents aged 12–17 from the US were included. Predicted daily minutes of MVPA were calculated. The exposure variables of interest were the availability of school recreational facilities, indoor recreational facilities, playing fields, bike/hiking/walking trails or paths or public parks. Participants were excluded if no information was provided for MVPA or availability of recreational facilities. Unadjusted and adjusted linearregression analysis was used to calculate mean daily minutes of MVPA and their corresponding 95 % confidence intervals. In fully adjusted models, we found statistically significant associations between the type of recreational facility and differences in daily minutes of MVPA for school (p-value < 0.001) and public parks p-value < 0.001), but not for the other recreational facilities. The average daily minutes of MVPA differed by 4.4 min (95 % CI 2.6, 6.2) if participants had school recreational facilities, respectively. School recreational facilities are important for engaging adolescents in PA objectives. Features within school recreational facilities should be studied to further investigate contributions to increased PA levels.
