The Relationship between Physical Activity, Physical Fitness, Cognition, and Academic Outcomes in School-Aged Latino Children: A Scoping Review.

This scoping review provides an overview of the relationship between physical activity, physical fitness, cognition, and academic outcomes in Latino school-aged children and identifies areas for future research. A primary search was conducted in PubMed, PsycINFO, Web of Science, and ERIC for original-research articles meeting the inclusion criteria; the search results were uploaded into PICO Portal and assessed by two independent reviewers. Of the 488 initial search results, 50 articles were eligible for full-text review, and 38 were included in this review. Most studies were cross-sectional, conducted in the United States or Chile, and included children 5-18 years old. Overall, the majority of articles reported positive associations between physical activity or physical fitness and cognitive outcomes (n = 11/12; 91.7%), and physical activity or physical fitness and academic outcomes (n = 22/28; 78.6%). In sum, this review provided consistent evidence for higher amounts of physical activity and greater physical fitness to be associated with various positive cognitive and academic outcomes in a school-aged Latino population. This scoping review also elucidated a substantial gap in the research regarding study design, with a discernible lack of interventional efforts. Future studies should test physical activity interventional strategies to optimize cognitive and academic outcomes in school-aged Latino populations.

Prevalence of healthy diet and activity behaviours among U.S. Latino preschool children living in an emerging Latino community.

This pilot study provides preliminary insights into whether Latino preschool children living in an emerging Latino community (ELC) are meeting recommendations for healthy diet and activity behaviours and whether those behaviours are associated with sociodemographic or home environment variables. Secondary data analysis was conducted utilising cross-sectional baseline survey data from ANDALE Pittsburgh, a home-based intervention study. Measures included parent-reported information on child dietary intake, screen time and the home environment, and objectively measured physical activity and anthropometry. χ2 and Fischer's exact tests were used to determine associations. The study was conducted in an ELC in western Pennsylvania in the US. Fifty-one Latina mothers (age: 33⋅5 ± 6⋅1 years; 63 % Mexican origin; 86 % low acculturation) and their children (age: 3⋅9 ± 1⋅3 years; 55 % male) 2-5 years of age. On average, children consumed 2⋅25 ± 1⋅44 cups of fruits/vegetables, viewed 98⋅7 ± 74⋅2 min of screen time, accumulated 12⋅9 ± 2⋅9 min/h of total physical activity and consumed 15⋅5 ± 26⋅0 kcals of sugar-sweetened beverages per day. Forty-one percent met the fruit/vegetable recommendation, 54 % met the screen time recommendation, 27 % met the physical activity recommendation and 58 % met the sugary drink recommendation. Country of origin (P = 0⋅032) and acculturation (P = 0⋅048) were significantly associated with children meeting sugary drink recommendations. No other relationships were significant. The proportion of children in this sample meeting diet and activity recommendations was mixed. More research with larger sample sizes is needed in ELCs to identify effective intervention strategies for improving health behaviours.

Longitudinal changes in domains of physical activity during the transition from elementary school to high school in the U.S.

OBJECTIVES: To describe patterns of age-related change in self-reported physical activity domains within a heterogeneous sample of boys and girls in the U.S. transitioning from elementary to high school. DESIGN: Prospective cohort study. METHODS: Participants included n = 644 children recruited in 5th grade (10.5 ±â€¯0.5 years old, 45 % female) who completed the Physical Activity Choices survey at least twice over 5 time points (5th, 6th, 7th, 9th and 11th grade). Participants' self-reported physical activities were categorized into organized and non-organized activities, and a comprehensive variable was created as the product of the total number of physical activities reported in the past 5 days, the number of days spent in each activity, and the total time spent in each activity. Descriptive statistics and growth curve models (controlling for covariates) for the total sample and by sex were examined for total, organized, and non-organized physical activities from ages 10 to 17. RESULTS: There was a significant age by gender interaction (p < 0.05) for time spent in non-organized physical activities. Specifically, both sexes had similar patterns of decline before age 13, while boys increased after age 13 and girls declined and then maintained. In contrast, boys and girls declined in organized physical activities from ages 10 to 17 (p < 0.001). CONCLUSIONS: We observed stark differences in the age-related change between organized and non-organized physical activities and marked differences in the patterns of non-organized physical activities between boys and girls. Future research should examine physical activity interventions that consider age-, sex-, and domain-specific physical activity options for youth.

Feasibility of student-designed, peer-led classroom physical activity breaks in graduate school.

Objective: We evaluated the feasibility of Pitt Moves, a classroom-based, peer-led physical activity break (PAB) intervention developed by graduate students to improve mood, focus, and boredom among students. Participants: One hundred and thirty-two graduate-level students in 10 courses during an academic semester. Methods: Process evaluation with a formative focus involving document review, surveys, and interviews with students and facilitators. Results: Eighty-four percent of eligible students participated in ≥1 of 65 PABs. Participants said Pitt Moves provided a mental break, promoted community building, and increased their physical activity. They recommended increasing accessibility. Organizers' time was a constraint in running this program. Conclusion: Pitt Moves was feasible based on successful recruitment of participants, delivery of PABs as planned, and participant acceptability. A formal study should evaluate whether Pitt Moves can improve mood, focus, and boredom among graduate students. Organizational encouragement and audiovisuals could enhance marketing and program implementation.

Planning for a Healthy Aging Program to Reduce Sedentary Behavior: Perceptions among Diverse Older Adults.

Reducing prolonged engagement in sedentary behavior is increasingly considered a viable pathway to older-adult health and continued functional ability. Community-based programs that aim to increase physical activity can improve programs' acceptability by integrating older adults' perspectives on sedentary behavior and healthy aging into their design. The purpose of this study was to better understand the perceptions of a diverse group of community-dwelling older adults regarding sedentary behavior and its influence on healthy aging. Six focus group discussions with forty-six participants took place across two senior centers in New York City. Self-report questionnaires about daily activity patterns, general health status, and typical sedentary behaviors were also completed by the participants and analyzed using descriptive statistics. The focus group discussions were audio-recorded, transcribed, and analyzed using inductive and deductive approaches and an ecological framework to identify salient themes. A qualitative analysis revealed that the participants were aware of the physical costs of engaging in prolonged sedentary behavior. However, many routine sedentary activities were perceived to be health-promoting and of psychological, cognitive, or social value. The insights gained can inform the development of senior-center programs and health-promotion messaging strategies that aim to reduce older adults' sedentary behavior.

Effectiveness of a Promotores Network to Improve Health in an Emerging Latino Community.

BACKGROUND: Latinos living in emerging communities (i.e., nontraditional destinations with a small but growing population) face obstacles to their mental and physical health. This study evaluated the effectiveness of a 6-month, promotor-led intervention on access to care, physical activity, dietary practices, and perceived social support among Latino adults living in an emerging community, compared with a nonrandomly assigned control group. METHOD: Participants (n = 81 intervention; n = 86 control) were drawn from Allegheny county, Pennsylvania. Promotores used an intervention tool offering nondirective social support to assist participants in developing SMART goals to address their life concerns in eight domains (e.g., social, diet, and exercise/recreation); the control group received printed materials. Participants completed a survey in Spanish at baseline and follow-up to assess outcomes and had their height and weight measured. Adjusted linear mixed effects models compared change in outcomes over time. RESULTS: There was a marginally significant improvement in dietary practices in the intervention group at follow-up, and no change in access to care. Both groups experienced an improvement in social support. There was a significant intervention-by-time interaction such that the intervention group increased physical activity by 259 minutes/week compared with the control group. CONCLUSION: This study demonstrates the potential effectiveness of a promotores network in assisting individuals living in an emerging Latino community to address their life concerns and improve health behaviors. Future studies should include objective and more rigorous measures with a larger sample to replicate these results.

Patterns of age-related change in physical activity during the transition from elementary to high school.

This study was designed: 1) to describe patterns of age-related change in total and moderate-to-vigorous physical activity (MVPA) in children as they transitioned from elementary school to high school, and 2) to determine if those patterns differed across demographic sub-groups formed on the basis of gender, race/ethnicity, parent education (socioeconomic status), and urbanicity. A cohort of children (analysis sample, N = 951) was comprised of students drawn from two public school districts in South Carolina. Physical activity was measured by accelerometry on at least two and up to five occasions between 2010 and 2017. Growth curve analyses were performed to describe the pattern of age-related change in the physical activity variables for the full sample and for demographic sub-groups. A relatively steep age-related decline in total physical activity was observed in children before age 14, with a slower rate after that age. Physical activity was lower in girls than boys, and the age-related rate of decline was steeper in girls. Physical activity patterns did not differ across race/ethnicity groups, but children of parents with less education were more active than children of parents with more education. Children living in rural areas participated in less MVPA than children living in urban settings, and this difference increased with increasing age. These findings indicate that children experience a particularly steep decrease in physical activity as they transition from elementary to middle school, and this trend is particularly prominent in girls, children living in rural areas, and children of parents with college education.

Maternal Sedentary Behavior and Physical Activity across Pregnancy and Early Childhood Growth.

Background: Evidence suggests in utero exposures are related to lifespan health of the offspring. Whether maternal activity profile during pregnancy impacts offspring health remains unknown. Methods: This follow-up study recruited mothers with objectively measured sedentary behavior (SED) and moderate-to-vigorous intensity physical activity (MVPA) from a previous cohort study. Maternal activity was analyzed across pregnancy (trajectory groups) and continuously by trimester. Offspring anthropometrics up to 24 months were abstracted from medical records (n = 62). Outcomes included childhood growth rate (incremental rate of BMI z-score change up to 24 months) and rapid growth (increased BMI z-score >0.67 at 12 months). Associations of maternal activity with growth rate were examined using mixed linear models and rapid growth using generalized linear models. Results: Forty percent of participants were in the high SED and 20% in the high MVPA trajectories during pregnancy. Higher SED, across pregnancy [slope (95% confidence interval; CI): 0.080 (0.024-0.061) ΔBMI z-score/month] and in the first trimester [standardized beta; std ß (95% CI): 0.017 (0.007-0.026)], was related to accelerated growth rate. Higher MVPA, in the second and third trimesters, was associated with accelerated growth rate [std ß (95% CI): trimester 2: 0.013 (0.002-0.024) and trimester 3:0.011 (0.003-0.020)] and greater risk of rapid growth [risk ratio (95% CI): trimester 2: 1.25 (1.009-1.555) and trimester 3: 1.25 (1.056-1.475)]. Conclusions: These findings add to growing evidence on the deleterious effects of high SED during pregnancy. The increased risk for accelerated growth with higher MVPA elicits further investigation. Overall, maternal activity profile shows promise as a modifiable behavior to improve intergenerational health.

Pedagogic Tailoring of a Human Research Ethics Training for Community-Engaged Research With Latinos.

Because of the increase in community-engaged research, several human research ethics trainings for laypeople have been developed. We aim to (1) describe the pedagogical tailoring of a research ethics training for laypeople for a research study where promotores-community health workers-delivered an intervention to increase health care access and promote healthy behaviors among Latinos and (2) present results of the application of the training after 4 months in the field. We tailored a previously developed training to Latino community members implementing a research study. Key modifications included (1) translation (2) use of pedagogical tools, such as cooperative learning, role-plays, and inclusion of cultural preferences. One novel addition was to use dialogues that the trainees enacted and then discussed. We evaluated the training with a posttraining survey with eight community liaisons and 13 promotores implementing the intervention, and a focus group with eight promotores, 4 months after working in the field. Trainees said they felt confident obtaining informed consent, felt the dialogues were realistic and helped them remember what they learned, and wanted more feedback from trainers on their performance. Promotores demonstrated the application of ethical principles beyond the training by discussing the possibility of advertising broadly in social media (justice), the risks and benefits of providing community resources to participants (beneficence), and the university's role in legitimizing their position as promotores (respect). We conclude that a pedagogically tailored ethics research training for laypeople can be successful and that dialogues to be enacted need to be explored further.

Maternal Sedentary Behavior and Physical Activity across Pregnancy and Early Childhood Motor Development.

Early childhood motor development is an important indicator of short- and long-term health. In utero exposures impact offspring health across the lifespan; however, whether maternal activity during pregnancy may impact early childhood motor development remains unknown. This prospective cohort study measured the motor development skills of n = 70 children born to mothers from a previously conducted cohort study which objectively measured activity profile, (sedentary behavior (SED) and moderate-to-vigorous intensity physical activity (MVPA), across pregnancy. Mothers reported the motor development of their child using the Early Motor Questionnaire (EMQ). Linear regression models examined associations between maternal activity profile and EMQ scores. Maternal SED and MVPA were analyzed in two ways: trimester-specific and across pregnancy using trajectory groups. Children were 12-30 months of age, majority white (82%), and 52% male. Maternal SED during pregnancy was not associated with any EMQ domains (gross motor, fine motor, and perception action). Higher maternal MVPA, across pregnancy by trajectory group and in the first and second trimesters, was significantly associated with moderate-sized effects of more advanced fine motor and perception action scores. Higher MVPA in early pregnancy appears to be related to more advanced early childhood motor development. Therefore, maternal MVPA may be a modifiable behavior by which short- and long-term offspring health may be impacted.

Implementation Monitoring of a Promotora-Led, Home-Based Obesity Prevention Pilot Study With Latino Preschool Children and Their Mothers.

BACKGROUND: Latino preschool children have higher rates of obesity than children from other racial/ethnic backgrounds. Few effective, culturally-tailored obesity prevention interventions exist that have focused on Latino preschool children, and even fewer have published results of the process evaluation. The purpose of this paper was to monitor reach, fidelity, and completeness of implementation to determine whether ANDALE, a promising promotora-led, home-based pilot study to prevent obesity in Latino preschool children, was implemented as planned. METHODS: Guided by a logic model, we assessed reach, implementation fidelity and completeness through descriptive analyses of multiple data sources. Reach was assessed through attendance records. Fidelity was assessed via observation checklist and completeness was assessed via survey with both parents and promotoras in a subsample of 12 families. RESULTS: Promotoras recruited participants primarily through their own social networks and delivered the intervention to 50 families (mother-child dyads); the majority were of Mexican-origin, low-acculturation, dual-parent households. Nearly all (98%) families completed the whole 10-week intervention. Results demonstrated completeness and fidelity of implementation were acceptable in a subsample of 12 families. In sum, 75% of families in the subsample met the criteria (≥75%) for overall implementation of essential program elements (i.e., reach, completeness, and fidelity). CONCLUSION: Evidence suggests that ANDALE was delivered with high levels of completeness and fidelity in this sample of Latino families with preschool-aged children. These results support implementation of ANDALE in a large, randomized trial.

Generational Status, Language Use, Parental Limit Setting, and Screen Time in US Latinx Children.

Latinx children engage in excessive screen time and are disproportionately affected by obesity. We examined the effect of generational status and language use on screen time in 6- to 11-year-old Latinx children and whether parental limit setting mediated that relationship. Participants included 3127 children (aged 9.2 ± 2.0 years; 54% male) from the 2011-2012 National Survey of Children's Health. Spanish language use was associated with 14.0 more minutes per day of screen time (P = .038); parental limit setting partially mediated this relationship (11.4%). Future research should explore the protective role of parental limit setting in reducing screen time in Latinx children.

Overcoming barriers to physical activity in underserved populations.

There is compelling evidence suggesting underserved populations, including racial/ethnic minorities and individuals with low socioeconomic status, are less likely to partake in sufficient amounts of physical activity (PA) at recommended levels. Communities of color and low-income individuals face institutional, societal, and environmental barriers that may prevent them from achieving adequate levels of PA. However, these communities also possess a wealth of knowledge, assets, and support that can be harnessed to help individuals meet PA guidelines. This paper outlines the barriers to PA and explores how to overcome them, drawing from case studies of successful, evidence-based interventions that use culturally- and linguistically- appropriate approaches to increase PA in underserved populations.

Changes in Diet Quality in Youth Living in South Carolina From Fifth to 11th Grade.

OBJECTIVE: To examine diet quality levels and changes in a diverse sample of youth from fifth to 11th grade, and interactions by race/ethnicity and socioeconomic status. DESIGN: Transitions and Activity Changes in Kids prospective cohort study. SETTING: Elementary, middle, and high schools in South Carolina. PARTICIPANTS: A sample of 260 fifth-graders (106 boys and 154 girls) with complete data at baseline and at least 1 time point each in middle school and in high school. MAIN OUTCOME MEASURE: Dietary intake assessed with the Block Food Screener for Kids (last week). Diet quality was assessed using energy-adjusted intakes of 5 food groups. ANALYSIS: Descriptive statistics and growth curve models for the total group and by gender for diet quality from fifth to 11th grade (P < 0.05). RESULTS: Both boys and girls had low levels of diet quality, which continued to decline through 11th grade. Significant main effects by race and poverty as well as a race by poverty interaction were observed. CONCLUSIONS AND IMPLICATIONS: Programs and policies that support healthy dietary patterns in children transitioning from elementary to middle and high school are needed. Specific efforts that focus on nutrition disparities in children from low-income and minority backgrounds are warranted.

Household Support for Physical Activity in Adolescent Girls Living in Primarily Low Socioeconomic Status Neighborhoods.

The purpose of this study was to examine the association between perception of household support and physical activity levels of adolescent girls living in primarily low socioeconomic status (SES) neighborhoods. The sample consisted of thirty-six adolescent girls (N=36; 60% non-Hispanic Black; mean age of 14.6 ± 1.3 [mean ± sd]; median body mass index (BMI) percentile of 90.5 [58.5, 97.0]) living in primarily low socioeconomic status (SES) neighborhoods. Trained researchers measured participants' height and weight, and administered questionnaires to assess perception of household support for physical activity and minutes per day participating in moderate-to-vigorous physical activity (MVPA) (3-Day Physical Activity Recall). Pearson's correlation, controlling for race, age, and BMI, was used to evaluate the association between perception of household support and adolescents' MVPA levels. There were no significant associations between measures of the perception of household support for physical activity and adolescents' MVPA levels. There were significant negative associations between total adult household support for physical activity (r=-0.51; p<.01) with BMI and the support provided by the closest adult in the household (r=-0.55; p<.01) with BMI. These data suggest that support for physical activity in the household for adolescents with higher BMI's may be warranted.

Guest Perceptions of Physical Activity Point-of-Decision Prompts at a Conservatory with Botanical Gardens.

Point-of-decision prompts are cost-effective strategies to promote physical activity in public spaces. This study explored how adult and child guests of a conservatory with botanical gardens perceived point-of-decision prompts that aimed to promote physical activity. Seven point-of-decision prompts were developed and displayed throughout the conservatory. Adult guests (n = 140) were invited to complete a voluntary and anonymous survey to assess awareness of point-of-decision prompts, adult-child interactions, and physical activity engagement. Descriptive statistics were calculated using SPSS version 23. Sixty-one percent of guests (n = 86) who responded to the survey noticed the point-of-decision prompts. Over 65% (n = 56) of those guests completed at least one of the physical activities, and 53% (n = 46) completed one to three. Of guests attending with (a) child(ren) (n = 17) who completed the survey, over half (n = 9) engaged in at least one physical activity together. In sum, the point-of-decision prompts were noticed by some guests in this public space. More research is needed to determine whether point-of-decision prompts are able to lead to sustainable behavior change.

Latino Parents' Perceptions of Physical Activity and Healthy Eating: At the Intersection of Culture, Family, and Health.

OBJECTIVE: To explore Latino parents' perspectives on healthy living and identify strategies to incorporate in a future child obesity intervention. DESIGN: Descriptive, qualitative study. SETTING: Participants were recruited from an emerging Latino community (area with low [ < 5%] yet growing concentrations of Latinos) in Allegheny County, PA. PARTICIPANTS: Thirty-two parents of preschool children participated in 5 Spanish-language focus groups. PHENOMENON OF INTEREST: Parents' perceptions of a healthy lifestyle (ie, physical activity and nutrition). ANALYSIS: Data were analyzed using the constant comparison method to identify salient categories, themes, and patterns. RESULTS: Three overarching themes were identified: (1) Healthy Living: Beyond One's Control; (2) Estamos Acostumbrados [We Are Used to a Certain Lifestyle]; and (3) Latin American and US Culture Conflict. In general, parents perceived maintaining a healthy lifestyle to require enormous effort and that change was difficult given a lack of knowledge and control. CONCLUSIONS AND IMPLICATIONS: Key intervention approaches with this population may include a focus on the family environment. Increasing knowledge, building self-efficacy, and modeling behavior through family recipe preparation and physical activity breaks may be necessary, as well as an emphasis on and orientation to community resources to support behavior change and physical activity and healthy eating habits.

ANDALE Pittsburgh: results of a promotora-led, home-based intervention to promote a healthy weight in Latino preschool children.

BACKGROUND: Latino preschool children have higher rates of obesity than preschool children from other racial/ethnic groups; however, few effective, culturally appropriate interventions exist targeting this group. The purpose of this study was to test the feasibility of a 10-week, promotora-mediated, home-based intervention to promote a healthy weight in Latino preschool children. METHODS: Trained promotoras (community health workers) delivered 10, 90-min weekly interactive and tailored sessions to Latino families living in Allegheny County. Participants were recruited through promotoras' own social networks and community gatherings, flyers, and word of mouth. Primary outcome measures included child body mass index (BMI) z-score and percentile. Secondary outcome measures included child objectively measured physical activity and dietary intake, and the home social and physical environment (e.g., parent health behaviors, parent self-efficacy, parental support, physical activity equipment in the home). The final analysis sample included 49 of 51 participants who completed both baseline and follow-up assessments. RESULTS: Participants included mothers (33.5 ± 6.1 years old) and their preschool-aged children who were primarily 1st generation immigrants from Mexico (65%). The primary analyses of BMI percentile and z-score showed no change post-intervention. However, there was a significant decrease in child BMI percentile for overweight and obese children from baseline to follow-up (p < .05). We also saw significant pre/post increases in child daily fruit and vegetable intake, and parent moderate-to-vigorous physical activity, fruit and vegetable servings per day, and self-efficacy; and significant decreases in child saturated fat and added-sugar intake, and child and parent screen time (p's < .05). CONCLUSIONS: Despite the short duration of the intervention and follow-up, this pilot study showed promising effects of a promotora-mediated intervention to promote a healthy weight in Latino preschool children.

Study Protocol for a Home-based Obesity Prevention Program in Latino Preschool Children.

PURPOSE: This paper describes the study design for ANDALE Pittsburgh, a culturally-appropriate, family-based intervention to promote a healthy weight in Latino preschool children. METHODS/DESIGN: The study was organized into two major phases: Phase I: Conduct focus groups with 30 Latino parents of preschool children to inform the development of a culturally-appropriate intervention; Phase II: Test the feasibility and effectiveness of the intervention with 50 families. Participants were recruited from an emerging Latino community through community gatherings, flyers, and word of mouth. Six promotoras (females >18 years, active in community) received 25 hours of training using the intervention curriculum finalized after Phase I. Promotoras delivered the home-based intervention to families over 10, 90-minute weekly sessions that included education, practice, and action (i.e., goal setting). Behavior modification constructs and strategies (e.g., goal setting, problem solving, social support), and building of self-efficacy through healthy recipe preparation and physical activity breaks, were also included. Outcomes (e.g., child BMI) were assessed pre- and post-intervention. Process evaluation assessed fidelity, dose, reach, recruitment, and contextual factors using multiple data sources and mixed methods. DISCUSSION: The ANDALE Pittsburgh study will expand the body of knowledge on interventions to promote a healthy weight in Latino preschool children living in an emerging Latino community. If successful, this approach will be evaluated in a future, larger-scale intervention and provide a potential model to help to address and prevent obesity in this population.

The Modifying Effects of Race/Ethnicity and Socioeconomic Status on the Change in Physical Activity From Elementary to Middle School.

PURPOSE: Youth physical activity (PA) levels differ by race/ethnicity and socioeconomic status (SES). It is well established that various multilevel factors may influence changes in PA. The present study examined whether the association between the change in individual, interpersonal, and environmental factors and the change in PA is modified by race/ethnicity or SES. METHODS: This study followed 643 youths and their parents from suburban and rural South Carolina participating in the Transitions and Activity Changes in Kids (TRACK) Study in 2008-2009 and 2010-2011. We assessed total PA in youth using accelerometry and categorized youth and parent survey data into blocks based on the socioecological model. Multivariate regression growth curve models evaluated whether the association between change in independent variables and change in PA was modified by race/ethnicity or SES. RESULTS: PA declined from fifth to seventh grade among all racial/ethnic and SES groups. Associations between the range of variables and change in PA were modified by race/ethnicity but not SES. Blacks did not share any common predictors of change in PA with whites or Hispanics. However, child-reported number of active friends was associated with total PA, and enjoyment of PA was associated with change in PA among both whites and Hispanics. Significant interactions by time varied by racial/ethnic group. CONCLUSIONS: The factors that influence changes in youth PA vary by race/ethnicity but not SES. These findings reinforce the complex nature of addressing PA behavior in diverse samples and further support the need for culturally appropriate interventions to promote PA in youth.
