Leisure time and occupational physical activity among racial or ethnic minorities

Latin dance and cognitive impairment: Importance of una Mezcla of culture and science

Latinos are one of the fastest growing minority groups of the older adult population. More culturally relevant forms of physical activity, such as dance are needed to engage the older Latino population. Dance is considered a type of physical activity and is fun, challenging, and socially engaging. Our research, among others, has shown that dance is an effective form of physical activity and has been shown to improve memory and overall health. Our research demonstrates the significance of culturally relevant physical activity interventions; and the importance of involving the perceptions and input of community members from the intended population.

Associations Between Social Support, Social Control, and Stage of Change With Self-Reported and Objectively Assessed Physical Activity in Adult Latino Dyads

Health behaviors such as physical activity (PA) are socially influenced, such that individuals from shared social networks or living environments may exhibit similar habits. This cross-sectional study examined associations of social support, social control, and family member stage of change with moderate-to-vigorous self-reported and objective PA in dyads of adult Hispanic family members. We used the Godin Leisure-Time Physical Activity Questionnaire to assess self-reported PA and accelerometry for objective PA. Validated scales assessed social support, social control, and stage of change. We performed multivariable multilevel analysis using generalized estimating equations (GEE) to account for within-dyad correlations. We conducted multivariable negative binomial regression for Metabolic Equivalent Task minutes (MET-minutes) (self-reported; N = 429) and accelerometer data (N = 356) and logistic regression for meeting PA guidelines (self-reported; N = 429). Most dyads were spouses (41%) or parents and adult children (32%). Individuals with high family support had 81% higher odds of meeting PA guidelines (1.81 adjusted odds ratio (aOR); 95% confidence interval [CI] = [1.06, 3.09]; p = .030) and 58% higher leisure-time MET-minutes of PA per week (1.58 adjusted incidence rate ratio [aIRR], 95% CI = [1.30, 1.91]; p < .0001) than those with low levels of support. Participants reporting medium-to-high family punishment were 98% higher in odds of meeting PA guidelines (1.98 aOR; 95% CI = [1.09, 3.61]; p = .025) and had 70% higher leisure-time MET-minutes of PA (1.7 aIRR; 95% CI = [1.36, 2.13]; p<.0001) compared with those with low scores. Participants with study partners in action or maintenance stages had significantly higher leisure-time MET-minutes of PA per week (aIRR = 1.45, 95% CI = [1.10, 1.91], p = .009 and aIRR = 1.33, 95% CI = [1.01, 1.76], p = .041, respectively) compared with those with partners in other stages. No statistically significant associations were observed for social control with any measure of PA or between psychosocial measures and accelerometer-assessed PA. Our findings demonstrated that interventions should engage social networks and multimodal forms of PA assessment to optimize behavior change in similar populations.

Systematic Review and Meta-Analysis of the Effects of Dance on Cognition and Depression in Healthy Older Adults

PURPOSE

Aging is associated with declines in cognition and mental health that might be ameliorated by physical activity (PA). Dance integrates multiple physical, cognitive, and social elements, and might be an avenue for improving cognition and mood. This systematic review and meta-analysis examined the effects of formal and traditional dance on cognition, depression, and anxiety in older adults.

METHODS

Five database searches yielded 17 randomized control trials (RCTs). RCTs were included if participants were ≥60 yr and healthy or living with mild cognitive impairment. We examined interventions of dance against any comparison group. Records were independently screened, and data were extracted by two reviewers. We performed random-effects models using robust variance estimation and tested individual treatment, study, and outcome-level moderators using the approximate Hotelling-Zhang test.

RESULTS

Seventeen RCTs were included in the systematic review, but 13 RCTs were included in the meta-analysis, which included 1174 participants with a mean age of 70.7 yr, and 66.3% were female. There were 76 effect sizes (Hedges g) calculated from the 13 RCTs with a range between -0.97 and 2.88. The overall effect of dance interventions on cognition was significant, yet small (g = 0.27; 95% confidence interval, 0.05-0.50; P = 0.022), and the effect on depression was significant and nearly moderate (g = 0.43; 95% confidence interval, 0.06-0.80; P = 0.036); only one RCT examined anxiety and was not included. No moderator variables significantly explained variation in the effects of dance on cognitive function or depression (P > 0.05).

CONCLUSIONS

Dance interventions can improve cognition and depression in older adults. Additional research is needed regarding the effects of dance on anxiety and depression in older adults.

Associations of Physical Activity and Sedentary Behavior With Mental Distress According to Caregiver Status: Analysis of the Health Information National Trends Survey, 2022

PURPOSE

To (1) examine how physical activity and sedentary behavior are related to mental distress and (2) identify and compare how various levels of sedentary behaviors may differentially predict mental distress after accounting for physical activity, among caregivers vs non-caregivers.

DESIGN

Cross-sectional secondary data.

SETTING

National Cancer Institute's Health Information National Trends Survey Cycle 6 fielded online from March-November 2022.

PARTICIPANTS

U.S. adults aged 18 and older.

MEASURES

The Patient Health Questionnaire-4 was administered along with caregiving status, moderate weekly physical activity, sedentary behavior, and sociodemographic characteristics.

ANALYSIS

After applying population weights, we conducted multiple adjusted logistic regression models and estimated predictive margins to understand whether a specific dose of sedentary behavior (hours/day) is associated with risk of mental distress, at different levels of physical activity.

RESULTS

Caregivers (15.41% of sample) reporting 10-hour of daily sedentary behavior were significantly more likely to experience mental distress, than those reporting lower amounts of sedentary behavior (OR = 3.372, 95%CI = 1.968, 5.776, P < 0.001). Regardless of physical activity amount, 10 hours of sedentary behavior may be a risk factor for mental distress among non-caregivers. Just 6 hours of sedentary behavior may be related to mental distress among caregivers.

CONCLUSION

Physical activity interventions tailored to caregivers' needs, responsibilities, and circumstances are required. Innovative methodologies are needed to understand caregivers' daily behaviors and the intensity of their caregiving activities.

Comparing Barriers and Facilitators to Physical ActivityAmong Underrepresented Minorities: Preliminary Outcomes from a Mixed-Methods Study

Physical activity (PA)'s benefits are well established, yet many U.S. adults fail to meet PA guidelines. This is especially true for minorities facing social inequities. This study explored PA's barriers and facilitators among urban Midwestern minorities using a mixed-methods approach framed on the socio-ecological model. A cross-sectional survey was conducted between January and June 2024 among community-dwelling minorities. Participants were grouped as completing low (LLPA) or high (HLPA) weekly leisure-time PA for comparison. Quantitative analysis included MANOVA, follow-up ANOVAs, and calculation of effect sizes. Qualitative data were assessed using inductive thematic analysis. Twenty-nine adults (44.83% Black, 41.37% Latino) participated in the study. The HLPA group (n = 18) reported higher leisure-time PA (p = 0.001, d = 2.21) and total PA (p = 0.02, d = 1.00) compared to the LLPA group (n = 11). LLPA participants faced more personal barriers to PA (p = 0.02, d = -0.92). Common barriers identified in the interviews included a lack of time and financial costs. Facilitators included social support and available PA facilities. Both groups achieved the USPA guidelines through different PA domains. Increasing social support and lowering PA-related costs could enhance participation. Addressing barriers and leveraging existing facilitators are crucial to increasing PA among minorities.

Temporal trends in aerobic physical activity guideline adherence among nationally representative samples of U.S adults between 2011 and 2019: Cross-sectional findings from a sample of over 2 million adults

BACKGROUND

Physical inactivity is a significant public health concern associated with numerous adverse health outcomes and substantial economic costs. This study describes the prevalence, trends and correlates for adherence to moderate to vigorous physical activity (MVPA) guidelines among a large sample of U.S. adults.

METHODS

Data from the 2011, 2013, 2015, 2017, and 2019 Behavioral Risk Factor Surveillance System surveys were analyzed. Self-reported MVPA was assessed by the same item across each survey. Population-weighted prevalence was calculated for meeting MVPA guidelines (150+ mins/wk). Adjusted prevalence ratios for reporting sufficient MVPA across sociodemographic, behavioral and health variables were calculated by multivariate Poisson regression.

RESULTS

Data was available for 2,052,288 respondents (≥ 18 years). Across the surveys, the prevalence of sufficient MVPA fluctuated but remained between 49.5% and 51.1%. Among those aged 18 to 24, the prevalence of sufficient MVPA declined between surveys, from 56.5% in 2011 to 49.7% in 2019. Notable correlates of adhering to guidelines included male sex, higher education, former and never smokers, normal body mass index and increased fruit and vegetable consumption.

CONCLUSION

From 2011 to 2019, approximately half of US adults reported sufficient MVPA, with a steady decline observed among young adults. While many identified correlates of adhering to PA guidelines were observed, this study has provided further evidence for correlates that had previously provided inconsistent or inconclusive results. These findings emphasize the complexity of addressing physical inactivity and the importance of multifaceted public health strategies tailored to diverse populations.

Changes in the Perceptions of the Neighborhood Environment and Physical Activity Patterns Among Mexican Americans on the Texas-Mexico Border

INTRODUCTION

Little research on the association of neighborhood environment with physical activity in resource-poor communities has been done. This study assessed changes in perceptions of the neighborhood environment and the association between those perceptions and physical activity in Mexican Americans on the Texas-Mexico border in an area where there would be community efforts to enhance pedestrian and cycling infrastructure and programming.

METHODS

We analyzed data from a population-based cohort of Mexican American individuals on the Texas-Mexico border. From 2008 to 2018, interviewer-administered questionnaires were used to collect perceptions of neighborhood environment and physical activity at baseline, 5- and 10-year follow-ups, and at other ancillary study visits, with an average of 3 data points per participant. We conducted multivariable longitudinal logistic regression analyses to assess if the changes in odds of positive perceptions of the neighborhood environment over the study years differed by physical activity patterns.

RESULTS

The sample (n = 1036) was mostly female (71%), born in Mexico (70%), and had no health insurance (69%). We saw improvements in the perceptions of several neighborhood environment attributes from 2008 to 2018, though we saw different longitudinal trajectories in these perceptions based on an individual's longitudinal physical activity patterns. By 2014-2018, we saw significantly higher positive perceptions of the neighborhood environment for those who consistently met physical activity guidelines compared with those who did not (adjusted rate ratio = 1.12, P = .049).

DISCUSSION

We found that perceptions of many neighborhood environment attributes improved between 2008 and 2018, and that overall positive perceptions were associated with consistently meeting physical activity guidelines over time.

Domain matters: An examination of college student physical activity participation patterns by gender and race/ethnicity

BACKGROUND

Physical activity (PA) consists of multiple domains, including leisure-time PA (LTPA), occupational PA (OPA), and transportation PA (TPA), though limited research has examined these domains among college students.

METHODS

This cross sectional, online survey asked undergraduate students to self-report demographics (gender, race/ethnicity, employment) and PA (LTPA, TPA, and OPA). Participants were categorized as meeting/not meeting current aerobic PA recommendations with only LTPA and with all domains of PA. Analyses examined differences by domain and demographics.

RESULTS

For participants (n = 3732) when only considering LTPA, 79% met recommendations, while considering all forms of PA resulted in 94% of students meeting recommendations. Gender and race/ethnicity differences in the odds of meeting PA recommendations were present with only LTPA, however when considering all PA domains, some disparities were no longer present.

CONCLUSIONS

These findings highlight how different domains of activity contribute to overall PA and the relationship with gender and race/ethnicity.

Association Between Leisure-Time Physical Activity and Occupation Activity Level, National Health Interview Survey-United States, 2020

BACKGROUND

Physical activity for any purpose counts toward meeting Physical Activity Guidelines (PAG). However, national surveillance systems traditionally focus on leisure-time physical activity. There is an incomplete understanding of the association between meeting PAG in leisure time and occupation activity level among US workers.

METHODS

We used cross-sectional 2020 National Health Interview Survey data to examine US adults aged 18-64 years who worked the week before the survey (n = 14,814). We estimated the proportion meeting aerobic and muscle-strengthening PAG in leisure time by occupation activity level (low, intermediate, and high). Using logistic regression, we examined the association between meeting PAG in leisure time and occupation activity level, adjusted for sociodemographic characteristics and stratified by hours worked. We compared the sociodemographic characteristics of adults working ≥40 hours (the previous week) in high-activity occupations to those in low- or intermediate-activity occupations.

RESULTS

Adults working in high-activity occupations were less likely to meet PAG in leisure time (26.1% [24.3-28.1]) versus those in low-activity (30.6% [29.1-32.2], P < .01) or intermediate-activity (32.4% [30.8-34.2]) occupations. In stratified, adjusted models, adults working ≥40 hours in low- and intermediate-activity occupations were 13% and 20%, respectively, more likely to meet PAG in leisure time versus those in high-activity occupations. Among those working ≥40 hours, adults in high-activity occupations were more likely to be Hispanic or Latino, male, younger, and have a high school education or lower compared with those in less active occupations.

CONCLUSION

Traditional surveillance may underestimate meeting PAG among people working in high-activity occupations, potentially disproportionately affecting certain groups.

Latin Dance Effects on Cardiorespiratory Fitness and Physical Function in Middle-Aged and Older Latino Adults

We tested if a dance trial yielded improvements in physical function and cardiorespiratory fitness (CRF) in middle-aged/older Latino adults. Physical activity was assessed using the Community Healthy Activities Model Program for Seniors, physical function with the Short Physical Performance Battery (SPPB) protocol, and estimated CRF with the Jurca nonexercise test model. Multivariate analysis of covariance models found significant change in SPPB protocol total scores, F(1, 329) = 4.23, p = .041, and CRF, F(1, 329) = 5.16, p = .024, between the two study arms in favor of the dance group. Mediation models found moderate- to vigorous-intensity physical activity to mediate to mediate between group and SPPB scores (β = 0.054, 95% confidence interval [0.0142, 0.1247]). Moderate- to vigorous-intensity physical activity and total physical activity were found to partially mediate between group and CRF (β = 0.02, 95% confidence interval [-0.0261, 0.0751]), with the direct pathway no longer being significant (p > .05). This provides support for Latin dance programs to have an effect on SPPB protocol and CRF.

The association between work-related activities and leisure-time physical activity among Latinos

OBJECTIVES

Latinos engage in high levels of occupational physical activity, yet low levels of leisure-time physical activity. Limited research has examined specific work-based activities that may contribute to leisure-time physical activity for meeting current physical activity recommendations among Latinos. The purpose of our study was to examine associations between frequency of work-related exertion and standing/walking with meeting the aerobic and muscle-strengthening physical activity guidelines among Latinos and whether associations varied by nativity.

DESIGN

We used cross-sectional 2015 National Health Interview Survey data on Latinos ≥18 years of age (n = 3162). Logistic regression models were used to estimate associations between the frequency of work-related activities with meeting the aerobic and muscle-strengthening physical activity guidelines. Models were adjusted for age, sex, education, Latino subpopulation, shift work, and nativity. We also examined whether associations varied by nativity.

RESULTS

In adjusted models, compared with those never engaging in exertion at work, participants always exerting themselves were significantly less likely to meet the aerobic activity guideline (Odds Ratio [OR]: 0.66, 95% Confidence Interval [CI]: 0.51-0.87). Compared with those never standing/walking at work, participants seldom standing/walking were also less likely to meet the aerobic activity guideline (OR: 0.57, 95% CI: 0.34, 0.95). Models were adjusted for age, sex, education, Latino subpopulation, shift work, and nativity. When stratified by nativity, the patterns in the strength of the associations were similar, while differences were observed in the associations of work-related activities with meeting guidelines.

CONCLUSION

Our findings suggest that engaging in higher frequency of exertion and standing/walking at work are associated with being less likely to meet the aerobic physical activity guideline during leisure time among Latinos, with variation observed in meeting guidelines by nativity. Insight into physical activities performed at work could inform efforts aimed at promoting recommended levels of physical activity among Latinos.

Promoting Physical Activity Among Immigrant Asian Americans: Results from Four Community Health Worker Studies

Racial/ethnic minorities have demonstrated lower rates of physical activity (PA) than non-Hispanic Whites. This study examined outcomes in PA measures after participation in a community health worker (CHW) intervention. We performed a secondary data analysis from four randomized controlled trials utilizing CHWs (n = 842) in New York City (Bangladeshi-diabetes management, Filipino-hypertension management, and Korean and Asian Indian-diabetes prevention). Outcomes included total weekly PA, PA self-efficacy, PA barriers, and PA social interaction. Each measure was examined at baseline and study endpoint. Generalized estimating equation models were fitted to assess the repeated measures over time, while accounting for study group and socio-demographic factors. Moderate PA, recommended PA, and self-efficacy increased significantly among treatment group participants. PA social interaction increased significantly among Filipinos and Asian Indians. In adjusted regression analysis, time x group interaction was significant for all PA outcomes except for PA barriers. Culturally-adapted lifestyle interventions may potentially improve PA-related outcomes in Asian immigrant communities. Trial registration at ClinicalTrials.gov includes: NCT03530579 (RICE Project), NCT02041598 (DREAM Project), and NCT03100812 (AsPIRE).

Gender and race/ethnicity differences in occupational activity among students

Occupational physical activity (OPA) is related to positive health outcomes and meeting overall physical activity recommendations. OPA participation typically varies across racial/ethnic groups and by gender, though little research has examined differences in OPA among college students. A cross-sectional, online survey of college students examined demographics and OPA. Participants (n = 3739) were predominately Non-Hispanic White (77.1%) and female (57.8%) aged 20.97 ± 1.52. Employed students reported greater total PA compared with non-employed students. Males reported significantly greater vigorous OPA, overall OPA, and total PA compared with females. Among employed students, OPA contributed significantly to overall PA levels. Males reported significantly greater OPA compared with females and there were several significant differences by race/ethnicity. Academic performance was related to OPA. These findings provide some insight on the OPA levels of a population group that has not been thoroughly examined.

Physical activity in birth cohorts of three Brazilian cities (Ribeirão Preto, Pelotas, and São Luís): A cross-sectional study

OBJECTIVE

To describe the prevalence of physical activity among subjects from birth cohorts of three cities located in different regions of Brazil according to sociodemographic characteristics and sex, comparing the relationships within and between cohorts.

METHODS

Cross-sectional study involving 12,724 adolescents and young adults who participated in five birth cohorts: Ribeirão Preto [1978/79 (37/39 years old in 2016) and 1994 (22 years in 2016)]; Pelotas [1982 (30 years in 2012) and 1993 (22 years in 2015)], and São Luís [1997/98 (18/19 years in 2016)]. Leisure-time physical activity was evaluated with questionnaires (insufficiently active: <150 min/week and active: ≥150 min/week) and moderate and vigorous physical activity (MVPA) was objectively measured by accelerometry. Those, in each city, were evaluated accordingly to skin color, socioeconomic classification, and study/work activities.

RESULTS

The prevalence of leisure-time physical activity ranged from 29.2% at 30 years old in Pelotas to 54.6% among adolescents from São Luís. The prevalence of leisure-time physical activity was higher among younger people (54.6% in São Luís 1997), while the same was not observed for total physical activity. MVPA (3rd tercile) was higher in the cohorts from Pelotas and São Luís. The prevalence of leisure-time physical activity and MVPA was higher in men. The data showed that the variation in physical activity was associated with sex and sociodemographic conditions in all cohorts.

CONCLUSION

Sociodemographic characteristics should be considered when promoting leisure-time physical activity and actions aimed at young people, and adults who are more socioeconomically vulnerable should be encouraged.

Physical Activity as a Mediator Between Race/Ethnicity and Changes in Multimorbidity

OBJECTIVES

Studies report racial/ethnic disparities in multimorbidity (≥2 chronic conditions) and their rate of accumulation over time as well as differences in physical activity. Our study aimed to investigate whether racial/ethnic differences in the accumulation of multimorbidity were mediated by physical activity among middle-aged and older adults.

METHOD

We assessed racial/ethnic differences in the accumulation of multimorbidity (of 9 conditions) over 12 years (2004-2016) in the Health and Retirement Study (N = 18,264, mean age = 64.4 years). Structural equation modeling was used to estimate latent growth curve models of changes in multimorbidity and investigate whether the relationship of race/ethnicity (non-Hispanic Black, Hispanic, non-Hispanic White participants) to changes in the number of chronic conditions was mediated by physical activity after controlling for age, sex, education, marital status, household wealth, insurance coverage, smoking, alcohol, and body weight.

RESULTS

There was a significant increase in multimorbidity over time. Initial levels and changes in multimorbidity over time varied significantly across individuals. Indirect effects of the relationship between race/ethnicity and changes in multimorbidity as mediated by physical activity were significant, consistent with the mediational hypothesis. Black respondents engaged in significantly lower levels of physical activity than White respondents after controlling for covariates, but there were no differences between Hispanic and White respondents once education was included. Discussion: These results provide important new information for understanding how modifiable lifestyle factors may help explain disparities in multimorbidity in mid-to-late life, suggesting greater need to intervene to reduce sedentary behavior and increase physical activity.

Quantifying physical activity across the midlife: Does consideration of perceived exertion matter?

Many questionnaires ascertain physical activity (PA) frequency, duration, and intensity to benchmark achievement of PA recommendations. However, most scoring algorithms utilize absolute intensity estimates when exertion may be influenced by age or health characteristics. This study quantified PA estimates with and without adjustments for perceived exertion and evaluated if differences were associated with individual-level characteristics. Women (n = 2,711) in the United States from the Study of Women's Health Across the Nation who completed ≥ 3 Kaiser Physical Activity Surveys (KPAS) across 8 biennial visits were included (baseline age: 46.4 ± 2.7 years). KPAS responses about activity mode and exertion were converted to metabolic equivalent of a task (METs) using the 2011 Compendium of Physical Activities to estimate absolute and perceived intensity-adjusted METs. Repeated measures (linear mixed effects) regression models were used to examine associations of sociodemographic and health-related characteristics with change in the difference between absolute MET estimates and perceived intensity-adjusted MET estimates. Older age (p < 0.001), Chinese (p < 0.001) and Japanese (p = 0.01) ethnicity, and current smoking (p = 0.001) were associated with positive differences between absolute and perceived intensity-adjusted MET estimates, which is suggestive of lower perceived-intensity physical activity. However, for most participants, absolute intensity-based estimates closely approximated perceived intensity-adjusted estimates over time. Traditional PA scoring techniques using absolute intensity estimates only may provide sufficient estimates of PA in longitudinal cohort studies of mid-life and older adult women.

Establishing a Framework for Gathering Structural and Social Determinants of Health in Alzheimer's Disease Research Centers

Structural and social determinants of health (SSDoH) are environmental conditions in which individuals are born, live, learn, work, play, worship, and age that affect health, functioning, and quality-of-life outcomes across the life course. Growing evidence suggests that SSDoH can help to explain heterogeneity in outcomes in Alzheimer's disease and Alzheimer's disease and related dementias (AD/ADRD) research and clinical practice. The National Institute on Aging has prioritized collecting SSDoH data to elucidate disease mechanisms and aid discovery of disease-modifying treatments. However, a major nexus of AD/ADRD research, the national network of Alzheimer's Disease Research Centers (ADRCs), collects few SSDoH data. We describe a framework for feasibly gathering and modeling SSDoH data across ADRCs. We lay out key constructs, their measures, and empirical evidence for their importance in elucidating disease and prevention mechanisms. Toward a goal of translation, the framework proposes a modular structure with a core set of measures and options for adjunctive modules. We describe considerations for measuring SSDoH in existing geographically and culturally diverse research cohorts. We also outline a rationale for universal implementation of a set of SSDoH measures and juxtapose the approach with alternatives aimed at collecting SSDoH data.

BAILA: A Randomized Controlled Trial of Latin Dancing to Increase Physical Activity in Spanish-Speaking Older Latinos

BACKGROUND

Latinos are the fastest growing minority group of the older adult population. Although physical activity (PA) has documented health benefits, older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance, popular among Latinos, holds promise as a culturally relevant form of PA.

PURPOSE

To describe self-reported and device-assessed changes in PA as a result of a randomized controlled trial of BAILAMOS, a 4-month Latin dance program with a 4-month maintenance program, versus a health education control group.

METHODS

Adults, aged 55+, Latino/Hispanic, Spanish speaking, with low PA levels at baseline, and risk for disability were randomized to the dance program (n = 167) or health education condition (n = 166). Data were analyzed using multilevel modeling with full information maximum likelihood.

RESULTS

A series of multilevel models revealed significant time × group interaction effects for moderate-to-vigorous physical activity (MVPA), dance PA, leisure PA, and total PA. Exploring the interaction revealed the dance group to significantly increase their MVPA, dance PA, leisure PA, and total PA at months 4 and 8. Household PA and activity counts from accelerometry data did not demonstrate significant interaction effects.

CONCLUSIONS

The study supports organized Latin dance programs to be efficacious in promoting self-reported PA among older Latinos. Efforts are needed to make dancing programs available and accessible, and to find ways for older Latinos to add more PA to their daily lives.

Evaluating the Dissemination and Implementation of a Community Health Worker-Based Community Wide Campaign to Improve Fruit and Vegetable Intake and Physical Activity among Latinos along the U.S.-Mexico Border

This study evaluated the dissemination and implementation of a culturally tailored community-wide campaign (CWC), Tu Salud ¡Si Cuenta! (TSSC), to augment fruit and vegetable (FV) consumption and physical activity (PA) engagement among low-income Latinos of Mexican descent living along the U.S.-Mexico Border in Texas. TSSC used longitudinal community health worker (CHW) home visits as a core vehicle to enact positive change across all socioecological levels to induce behavioral change. TSSC's reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) was examined. A dietary questionnaire and the Godin-Shepherd Exercise Questionnaire measured program effectiveness on mean daily FV consumption and weekly PA engagement, respectively. Participants were classified based on CHW home visits into "low exposure" (2-3 visits) and "high exposure" (4-5 visits) groups. The TSSC program reached low-income Latinos (n = 5686) across twelve locations. TSSC demonstrated effectiveness as, compared to the low exposure group, the high exposure group had a greater FV intake (mean difference = +0.65 FV servings daily, 95% CI: 0.53-0.77) and an increased PA (mean difference = +185.6 MET-minutes weekly, 95% CI: 105.9-265.4) from baseline to the last follow-up on a multivariable linear regression analysis. Multivariable logistic regression revealed that the high exposure group had higher odds of meeting both FV guidelines (adjusted odds ratio (AOR) = 2.03, 95% CI: 1.65-2.47) and PA guidelines (AOR = 1.36, 95% CI: 1.10-1.68) at the last follow-up. The program had a 92.3% adoption rate, with 58.3% of adopting communities meeting implementation fidelity, and 91.7% of communities maintaining TSSC. TSSC improved FV consumption and PA engagement behaviors among low-income Latinos region wide. CHW delivery and implementation funding positively influenced reach, effectiveness, adoption, and maintenance, while lack of qualified CHWs negatively impacted fidelity.

Association of physical activity with arterial stiffness among Black adults

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.

Association of Accelerometer-Measured Physical Activity and Cardiovascular Health in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

INTRODUCTION

Evidence regarding the associations between accelerometer-measured moderate-vigorous physical activity (MVPA) and cardiovascular health (CVH) indicators among Hispanic/Latino adults are unavailable.

METHODS

Examined cross-sectional data from 12,008 Hispanic/Latino adults aged 18-74 years participating in the Hispanic Community Health Study/Study of Latinos. Accelerometer-measured MVPA was assessed categorically and dichotomously per 2008 PA guidelines. Adverse and ideal CVH indicators were determined by standard cut-points for blood glucose, total cholesterol, blood pressure, body mass index (BMI), and smoking. A composite of low CV risk, defined as achieving all ideal CVH indicators, was included. Adjusted Poisson regression models and complex survey design methods were used for all analyses.

RESULTS

Compared to high MVPA, lower MVPA categories were associated with higher prevalence of all adverse CVH indicators, except hypertension, and with lower prevalence of low CV risk and ideal blood glucose, blood pressure, and BMI. Similarly, non-adherence to PA guidelines was associated with a higher prevalence of diabetes (16%), hypercholesterolemia (9%), obesity (28%), and smoking (9%); and lower prevalence of low CV risk (24%), ideal blood glucose (6%), ideal blood pressure (6%), and ideal BMI (22%).

CONCLUSION

Overall, high accelerometer-measured MVPA and meeting PA guidelines were associated with favorable CVH in Hispanic/Latino adults.

A Tailored Web- and Text-Based Intervention to Increase Physical Activity for Latino Men: Protocol for a Randomized Controlled Feasibility Trial

Background

Latino men in the United States report low physical activity (PA) levels and related health conditions (eg, diabetes and obesity). Engaging in regular PA can reduce the risk of chronic diseases and yield many health benefits; however, there is a paucity of interventions developed exclusively for Latino men.

Objective

To address the need for culturally relevant PA interventions, this study aims to develop and evaluate Hombres Saludables, a 6-month theory-based, tailored web- and text message-based PA intervention in Spanish for Latino men. This protocol paper describes the study design, intervention, and evaluation methods for Hombres Saludables.

Methods

Latino men aged 18-65 years were randomized to either the individually tailored PA internet intervention arm or the nutrition and wellness internet control arm. The PA intervention included 2 check-in phone calls; automated SMS text messages; a pedometer; a 6-month gym membership; access to a private Facebook group; and an interactive website with PA tracking, goal setting, and individually tailored PA content. The primary outcomes were feasibility, acceptability, and efficacy (minutes per week of total moderate-to-vigorous PA assessed via the ActiGraph GT3X+ accelerometer worn at the waist and 7-day physical activity recall at baseline and 6 months). Secondary outcomes examined potential moderators (eg, demographics, acculturation, and environmental variables) and mediators (eg, self-efficacy and cognitive and behavioral processes of change) of treatment effects at 6 months post randomization.

Results

This study was funded in September 2016. Initial institutional review board approval was received in February 2017, and focus groups and intervention development were conducted from April 2017 to January 2018. Recruitment for the clinical trial was carried out from February 2018 to July 2019. Baseline data collection was carried out from February 2018 to October 2019, with a total of 43 participants randomized. Follow-up data were collected through April 2020. Data cleaning and analysis are ongoing.

Conclusions

We developed and tested protocols for a highly accessible, culturally and linguistically relevant, theory-driven PA intervention for Latino men. Hombres Saludables used an innovative, interactive, web- and text message–based intervention for improving PA among Latino men, an underserved population at risk of low PA and related chronic disease. If the intervention demonstrates feasibility, acceptability, and preliminary efficacy, we will refine and evaluate it in a larger randomized control trial.

Physical activity, stress, and cardiovascular disease risk: HCHS/SOL Sociocultural Ancillary Study

We assess whether the cross-sectional associations between moderate-vigorous physical activity (MVPA) and CVD risk factors are modified by various stress types. Complete baseline data from 4,000 participants, ages 18-74 years, of the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (HCHS/SOL SCAS) were analyzed using complex survey design methods. Accelerometer-measured MVPA was assessed continuously (average minutes per day). CVD risk factors assessed were diabetes, hypercholesterolemia, hypertension, and obesity. Stress was assessed using the Chronic Burden Scale for chronic stress, Traumatic Stress Schedule for traumatic stress, and the Perceived Stress Scale for perceived stress. Poisson regression models estimated prevalence ratios of CVD risk factors. The interaction was evaluated by cross-product terms with p <0.10. There was a significant interaction between chronic stress and MVPA among those with prevalent diabetes (pinteraction = 0.09). Among those reporting low chronic stress, higher MVPA was associated with a low prevalence of diabetes, however among those reporting high chronic stress, the prevalence of diabetes remained high even with higher MVPA. We did not observe interactions between chronic stress and MVPA for the remaining CVD risk factors, or interactions between traumatic stress or perceived stress and MVPA. This study provides initial evidence on the role of chronic stress on the association between MVPA and diabetes for Hispanic/Latino adults. Mostly, however, chronic stress, traumatic stress, and perceived stress did not modify the associations between MVPA and CVD risk factors for Hispanic/Latino adults.

Are sedentary behavior and physical activity independently associated with cardiometabolic benefits? The Hispanic Community Health Study/Study of Latinos

BACKGROUND

Whether physical activity can reduce cardiometabolic risk particularly in understudied populations such as US Hispanics/Latinos is of public health interest. We prospectively examined the association of physical activity and cardiometabolic biomarkers in n = 8049 participants of the Hispanic Community Health Study/Study of Latinos, a community-based cohort study of 16,415 adults aged 18-74 yr who self-identified as Hispanic/Latino from four US urban centers.

METHODS

We assessed physical activity using accelerometry in 2008-2011 at visit 1. We assessed cardiometabolic biomarkers twice: once at visit 1 and collected a second measure in 2014-2017 at visit 2. We used survey linear regression models with changes in cardiometabolic markers as the dependent variables and quartiles of sedentary behavior or whether adults met guidelines for moderate-to-vigorous physical activity as the independent variables.

RESULTS

In normoglycemic adults without cardiovascular disease, but not in adults with evidence of cardiometabolic disease, those who were in the lowest quartile for sedentary behavior (< 10.08 h/day) had a significant decline in mean LDL-cholesterol of - 3.94 mg/dL (95% CI: - 6.37, - 1.52) compared to adults in the highest quartile (≥13.0 h/day) who exhibited a significant increase in LDL-cholesterol of 0.14 mg/dL (95% CI, - 2.15,2.42) over the six year period (P < 0.02 in fully adjusted models.) There was also a trend toward lower mean increase in HbA1c comparing the lowest with the highest quartile of sedentary behavior. Overall regardless of glycemic level or evidence of cardiometabolic disease, adults who met guidelines for moderate-to-vigorous physical activity at visit 1, had significantly lower mean increases in level of fasting glucose compared to adults not meeting guidelines in fully adjusted models.

CONCLUSIONS

In this cohort of Hispanics/Latinos, being free of cardiometabolic disease and having low levels of sedentary behavior were associated with health benefits. Among all adults regardless of cardiometabolic disease, meeting guidelines for moderate-to-vigorous physical activity was associated with health benefits. Overall these data suggest that an active lifestyle may blunt the association of advancing age with worsening cardiometabolic risk factors.

The Independent and Combined Effects of Aerobic Physical Activity and Muscular Strengthening Activity on All-Cause Mortality: An Analysis of Effect Modification by Race-Ethnicity

BACKGROUND

The effects of aerobic physical activity (PA) and muscular strengthening activity (MSA) on all-cause mortality risk need further exploration among ethnically diverse populations.

PURPOSE

To examine potential effect modification of race-ethnicity on meeting the PA guidelines and on all-cause mortality.

METHODS

The study sample (N = 14,384) included adults (20-79 y of age) from the 1999-2006 National Health and Nutrition Examination Survey. PA was categorized into 6 categories based on the 2018 PA guidelines: category 1 (inactive), category 2 (insufficient PA and no MSA), category 3 (active and no MSA), category 4 (no PA and sufficient MSA), category 5 (insufficient PA and sufficient MSA), and category 6 (meeting both recommendations). Race-ethnic groups examined included non-Hispanic white, non-Hispanic black, and Mexican American. Cox-proportional hazard models were used.

RESULTS

Significant risk reductions were found for categories 2, 3, and 6 for non-Hispanic white and non-Hispanic black. Among Mexican American, significant risk reductions were found in category 6.

CONCLUSION

In support of the 2018 PA guidelines, meeting both the aerobic PA and MSA guidelines significantly reduced risk for all-cause mortality independent of race-ethnicity. The effects of aerobic PA alone seem to be isolated to non-Hispanic white and non-Hispanic black.

Factors Associated with Use of Recreational Facilities and Physical Activity Among Low-Income Latino Adults

The purpose of this study was to identify longitudinal correlates of low-income, urban, Latino adults' use of recreational facilities and engagement in physical activity (PA). This secondary data analysis is from a placed-based initiative; the parent study recruited a cohort of parents of kindergarteners from schools in intervention and control communities. Using a self-administered questionnaire, we collected baseline correlates and 1-year follow-up recreational facilities use and PA outcomes. We conducted ordinal logistic regression to assess correlates for recreational facilities use and PA outcomes. Our sample of 273 Latino adults was mostly female and married or living with partners. Meeting PA guidelines at baseline was associated with higher odds of using parks, walking, and moderate- and vigorous-intensity PA. Those who considered PA to be important had higher odds of using trails (adjusted OR = 2.36, 95% CI 1.15-4.84) and of moderate-intensity PA (adjusted OR = 2.68, 95% CI 1.21-5.91). Reported perception that the neighborhood is very safe to walk was associated with higher odds of using trails (adjusted OR 3.45, 95% CI 1.39-8.53) and parks (adjusted OR 2.92, 95% CI 1.19-7.16). Quality of recreational facilities was directly associated with walking (adjusted OR = 1.61 95% CI 1.01-2.57). Speaking English was associated with higher odds of engaging in moderate-intensity PA (adjusted OR = 3.28 95% CI 1.70-6.33). Results from this study of urban, low-income Latinos indicate that promotion is needed not only for sustained use of recreational facilities among current users, but also for concerted efforts to reach less acculturated Latinos and make recreational facilities appealing to currently inactive adults. Both individual-level and neighborhood-level interventions are needed to build positive attitudes towards PA, while also enhancing neighborhood safety and the quality of neighborhood recreational facilities.

The association of acculturation with accelerometer-assessed and self-reported physical activity and sedentary behavior: The Hispanic Community Health Study/Study of Latinos

The adoption of US culture among immigrants has been associated with higher leisure-time physical activity and sedentary behavior. However, most research to date assesses this association using single measures of acculturation and physical activity. Our objective was to describe the cross-sectional association between acculturation and both physical activity and sedentary behavior among US Hispanic/Latino adults. Participants included Hispanic/Latinos 18-74 years living in four US locations enrolled in the Hispanic Community Health Study/Study of Latinos from 2008 to 2011. Acculturation was measured using acculturation scales (language and social), years in the US, language preference, and age at immigration. Physical activity and sedentary behavior were measured using the Global Physical Activity Questionnaire (N = 15,355) and Actical accelerometer (N = 11,954). Poisson, logistic, and linear regression were used, accounting for complex design and sampling weights. English-language preference was positively associated with self-reported leisure-time and transportation physical activity and accelerometer-assessed moderate-to-vigorous physical activity (MVPA). Social acculturation was positively associated with self-reported leisure-time and transportation physical activity and MVPA. Years in the US and age at immigration were positively associated with accelerometer-assessed MVPA. Language acculturation, years in the US, and age at immigration were associated with occupational physical activity among those who reported employment. Most acculturation measures were associated with self-reported sitting but not with accelerometer-assessed sedentary behavior. Different measures of acculturation, capturing various domains acculturation, were associated with physical activity and sedentary behavior. However, the direction of the association was dependent on the measures of acculturation physical activity/sedentary behavior, highlighting the complexity of these relationships.

Sedentary Time and Physical Activity Across Occupational Classifications

PURPOSE

To examine differences in activity patterns across employment and occupational classifications.

DESIGN

Cross-sectional.

SETTING

A 2005-2006 Coronary Artery Risk Development in Young Adults (CARDIA) study.

SAMPLE

Participants with valid accelerometry data (n = 2068).

MEASURES

Uniaxial accelerometry data (ActiGraph 7164), accumulated during waking hours, were summarized as mean activity counts (counts/min) and time spent (min/d) in long-bout sedentary (≥30 minutes, SED_≥30), short-bout sedentary (<30 minutes, SED_<30), light physical activity (LPA), short-bout moderate-to-vigorous physical activity (<10 minutes, MVPA_<10), and long-bout MVPA (≥10 minutes, MVPA_≥10) using Freedson cut-points. Employment status was self-reported as full time, part time, unemployed, keeping house, or raising children. Self-reported job duties were categorized into 23 major groups using the 2010 Standard Occupational Classification.

ANALYSIS

Omnibus differences were analyzed using adjusted analysis of covariance and repeated after stratification by race (black/white) and sex (female/male).

RESULTS

SED_≥30, SED_<30, LPA, and MVPA_<10 differed significantly by employment and occupational categories (P ≤ .05), while MVPA_≥10 did not (P ≥ .50). SED_≥30, SED_<30, and LPA differed by occupational classification in men, women, blacks, and whites (P < .05). Mean activity counts, MVPA_<10, and MVPA_≥10 were significantly different across occupational classifications in whites (P ≤ .05), but not in blacks (P > .05). Significant differences in mean activity counts and MVPA_<10 across occupational classifications were found in males (P ≤ .001), but not in females (P > .05).

CONCLUSION

Time within activity intensity categories differs across employment and occupational classifications and by race and sex.

Variability of Pain Outcomes and Physical Activity Among a Diverse Sample of Older Men: Is It More Than Just Race?

There is a compendium of data documenting the increasing number of older adults. This suggests the continued need to understand identified health outcomes across domains of pain and physical activity, particularly among older men. Therefore, the aim of this study was to evaluate race similarities and/or differences in pain and rates of physical activity among White, Black, and Hispanic men 60+ years of age. Data were taken from the Health and Retirement Study, a longitudinal panel study surveying a representative sample of people in the United States. Logistic regression analysis was used to examine associations between race and pain and the odds of regular physical activity. Results showed that Black men were less likely to participate in light or moderate/vigorous physical activity. Similarly, pain increased the odds of physical activity among Hispanics, but decreased the odds of physical activity among White men. Findings may reflect a number of factors that impact the well-being of what it means to experience pain and physical functioning, while also assuming a masculine identity. This perspective may allow for a better understanding of short- and long-term implications of the pain experience and the pain and physical functioning dyad among this group of men.

Moderate-vigorous physical activity and health-related quality of life among Hispanic/Latino adults in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

Background

Physical activity is a modifiable healthy behavior that has been shown to positively influence health-related quality of life. However, research examining the link between physical activity and health-related quality of life among Hispanic/Latino adults is limited and inconsistent. The purpose of this study is to assess whether accelerometer-measured moderate-vigorous physical activity (MVPA) is associated with self-reported (a) mental health-related quality of life, and (b) physical health-related quality of life among diverse Hispanic/Latino adults in the US.

Methods

Cross-sectional data from 12,379 adults ages 18–74 years in 2008–2011, who participated in HCHS/SOL and had complete data were analyzed using complex survey design methods. Accelerometer data were categorized into no MVPA, low, moderate, and high MVPA. Health-related quality of life was assessed with the Short-Form 12 and we used the mental and physical component subscales where higher scores indicate better health-related quality of life. Multivariate linear regression models were used to derive adjusted means with 95% confidence intervals and linear trends.

Results

We observed no significant linear trend between accelerometer-measured MVPA and mental health-related quality of life (p_trend = 0.73). There was a significant positive association between MVPA and physical health-related quality of life (p_trend < 0.001) where higher MVPA corresponded with higher scores in physical health-related quality of life. The adjusted means were 46.67 (44.85–48.48) for no MVPA, 49.33 (49.03–49.63) for low MVPA, 50.61 (50.09–51.13) for moderate MVPA, and 51.36 (50.86–51.86) for high MVPA.

Conclusions

Among diverse Hispanic/Latino adults in the US, accelerometer-measured MVPA was associated with physical health-related quality of life, but not mental health-related quality of life. Future interventions should evaluate if increases in MVPA lead to improvements in health-related quality of life.

Diabetes Prevalence by Leisure-, Transportation-, and Occupation-Based Physical Activity Among Racially/Ethnically Diverse U.S. Adults

OBJECTIVE

Leisure-time physical activity (LTPA) has been shown to prevent or delay the development of diabetes. However, little research exists examining how other domains of PA (e.g., occupation based [OPA] and transportation based [TPA]) are associated with diabetes prevalence across diverse racial/ethnic groups. We examined associations between OPA, TPA, and LTPA and diabetes prevalence and whether associations differed by race/ethnicity.

RESEARCH DESIGN AND METHODS

Participants in the 2011-2016 National Health and Nutrition Examination Survey (NHANES) self-reported domain-specific PA. Diabetes status was determined by self-reported doctor/health professional-diagnosis of diabetes or a glycosylated hemoglobin (HbA_1c) measurement of ≥6.5% (48 mmol/mol). Multivariable log binomial models examined differences in diabetes prevalence by PA level in each domain and total PA among Latinos (n = 3,931), non-Latino whites (n = 6,079), and non-Latino blacks (n = 3,659).

RESULTS

Whites reported the highest prevalence of achieving PA guidelines (64.9%), followed by Latinos (61.6%) and non-Latino blacks (60.9%; P < 0.0009). Participants achieving PA guidelines were 19-32% less likely to have diabetes depending on PA domain in adjusted models. Diabetes prevalence was consistently higher among non-Latino blacks (17.1%) and Latinos (14.1%) compared with non-Latino whites (10.7%; P < 0.0001), but interaction results showed the protective effect of PA was similar across PA domain and race/ethnicity-except within TPA, where the protective effect was 4% greater among non-Latino whites compared with Latinos (adjusted difference in risk differences 0.04, P = 0.01).

CONCLUSIONS

PA policies and programs, beyond LTPA, can be leveraged to reduce diabetes prevalence among all population groups. Future studies are needed to confirm potentially differential effects of transportation-based active living on diabetes prevalence across race/ethnicity.

The Longitudinal Relationship Between Social Support and Physical Activity in Hispanics

PURPOSE

Social support has been identified as a determinant of physical activity (PA), but research has been primarily cross-sectional, with mixed findings for different Hispanic subgroups and limited longitudinal research with Hispanics. The purpose of this study is to assess the longitudinal associations of social support with PA in Hispanics on the Texas-Mexico Border.

DESIGN AND SAMPLE

We used 2 time points of data collected from Hispanic adults in the Cameron County Hispanic Cohort (N = 588).

MEASURES

We collected social support for PA and self-reported leisure-time PA.

ANALYSIS

We used cross-lagged panel models to assess the association between friend support, family support, family punishment (criticizing or complaining) and PA over time.

RESULTS

Although social support overall was low for PA, fully adjusted cross-lagged panel models indicated that time 1 friend support was associated with time 2 PA (adjusted rate ratio = 1.02, 95% confidence interval = 1.00 -1.04), though family support was not associated with time 2 PA. In males, time 1 friend support was inversely associated with time 2 family punishment.

CONCLUSION

As expected, the directionality of the relation appears to be from social support to PA. Friend support appears to be predictive of PA in Hispanics, whereas family support is not. This should be considered in intervention development, particularly because familismo (commitment and mutual obligation to family) is considered to be a strong value in these communities.

Highlights From an Expert Meeting on Opportunities for Cancer Prevention Among Older Adults

This paper provides highlights from an expert meeting to explore opportunities to reduce cancer risk and promote health at older ages. Factors that increase cancer risk among older adults include exposure to carcinogens from multiple sources, chronic conditions such as obesity and diabetes, and unhealthy behaviors. Emerging research points to chronic social stressors - social isolation, loneliness, and financial hardship - as being linked to accelerated biological aging and increased cancer risk later in life. Older adults may disproportionately encounter these stressors as well as barriers to preventive health care services, accurate health information, and environments that promote health. Researchers can use existing cohort studies of older adults to deepen our understanding of the relative benefit of modifying specific behaviors and circumstances. The evidence points to the value of comprehensive, transdisciplinary approaches to promote health and reduce cancer risk across the entire lifespan, extending through older adulthood. Clinical encounters with older adults provide opportunities for psychosocial and behavioral screening and counseling. In the presence of multiple morbidities, preventive health services may offer greater health benefits than cancer-screening tests. Strategies that involve families and caregivers, promote positive attitudes about aging, and engage many different community sectors have the potential to prevent or delay the development of cancer at older ages.

The combined effect of physical activity and sedentary behavior on subclinical atherosclerosis: a cross-sectional study among Mexican Americans

BACKGROUND

Physical activity and sedentary behavior are considered independent risk factors for chronic disease. However, we do not fully understand their interrelation with key health outcomes such as subclinical atherosclerosis. This study examines the combined effects of sedentary behavior and physical activity on carotid intima-media thickness (cIMT) and presence of carotid plaque in a Mexican American population on the Texas-Mexico border.

METHODS

This cross-sectional study was conducted using retrospective data from a sample (n = 612) of participants from the Cameron County Hispanic Cohort. Carotid ultrasound was used to measure cIMT and presence of carotid plaque. Self-reported questionnaires were used to assess leisure time physical activity and sedentary behavior (TV/movie sitting and total sitting). A series of multivariable regression models were used to assess study aims. An interaction term between physical activity and sedentary behavior was included in models for each respective outcome. Models were controlled for demographic and health-related variables.

RESULTS

There were no significant associations found between physical activity, sedentary behavior and mean cIMT, or cIMT thickness ≥ 75th percentile for age and gender. However, there was a significant interaction between physical activity and TV/movie sitting with presence of carotid plaque. Participants who reported moderate levels of physical activity had significantly lower odds for presence of plaque compared to participants with no activity when TV/movie sitting time was ≤3 h per day. However, there was no significant difference in odds for presence of plaque between physical activity groups when TV/movie sitting exceeded 3 h/day. These results were consistent with models examining total sitting time.

CONCLUSIONS

Our results indicate that for Mexican Americans, there is a combined effect of sedentary behavior and physical activity on presence of carotid plaque. Participating in moderate physical activity is optimal for having lower levels of carotid plaque in addition to avoiding excessive levels of TV/movie sitting (≥3 h/day) and/or total sitting (≥8.5 h/day).

Nativity and Occupational Determinants of Physical Activity Participation Among Latinos

INTRODUCTION

Latinos in the U.S. bear a disproportionate burden of cardiovascular risk factors, including physical inactivity. Previous research among Latinos has focused on leisure-time physical activity, limiting understanding of the different ways in which populations, particularly working-class groups, achieve recommended levels of physical activity. This study examined associations of race/ethnicity; nativity; and leisure-time, transportation, and occupation-related physical activity among Latino and non-Latino white adults.

METHODS

Participants sampled in the 2007-2012 waves of the National Health and Nutrition Examination Survey self-reported domain-specific physical activity. Data were analyzed in 2016-2017 using multivariable log binomial regression models to examine differences in meeting guidelines for each physical activity domain separately and as total physical activity among Latinos (n=4,692) and non-Latino whites (n=7,788). Models were adjusted for sociodemographic characteristics and health status and tested interactions between nativity and occupational categories.

RESULTS

In adjusted models, foreign-born Latinos (prevalence ratio=0.70, 95% CI=0.63, 0.77) and U.S.-born Latinos (prevalence ratio=0.85, 95% CI=0.76, 0.95) were least likely to meet physical activity guidelines through occupation-related and leisure time physical activity, when compared with non-Latino whites. By contrast, foreign-born Latinos were more likely to meet physical activity guidelines through transportation physical activity than non-Latino whites (prevalence ratio=1.26, 95% CI=1.01, 1.56) and were proportionately more likely to participate in vigorous modes of physical activity. Interaction results indicated that foreign-born Latinos were the least likely to meet physical activity guidelines compared with U.S.-born Latinos and non-Latino whites if they worked in non-manual occupational categories. All racial/ethnic groups working in manual occupations saw the largest increase (40%-50%) in meeting physical activity guidelines when occupation-related physical activity was combined with leisure-time and transportation physical activity.

CONCLUSIONS

These findings suggest variability in the relationship between nativity and the physical activity domain Latinos engage in compared with non-Latino whites, with occupation contributing substantially to meeting physical activity recommendations for all population groups.

Systematic Review of Physical Activity Interventions in Hispanic Adults

INTRODUCTION

Physical activity (PA) has demonstrated substantial physical and psychological benefits. However, Hispanics engage in less leisure-time PA when compared with other groups, putting them at higher risk for diseases associated with obesity, such as diabetes mellitus type 2. This literature review was conducted to identify best practices with regard to interventions designed to increase PA among Hispanic adults.

METHODS

Extensive searching located 21 randomized controlled studies conducted in the United States.

RESULTS

Common conceptual frameworks were the transtheoretical model and social cognitive theory. Most interventions used educational sessions with a variety of topics and many used promotoras to increase PA. Outcomes were predominantly examined using self-report PA measures. Walking was the most commonly reported PA behavior. Studies with significant results were those that measured moderate-to-vigorous PA and used theory to guide interventions. Male and older participants were underrepresented.

CONCLUSIONS

Effective culturally appropriate PA interventions for Hispanics adults are needed. Particular attention to intervention tailoring based on country of origin could enhance intervention effectiveness.

Communicating and Assessing Physical Activity: Outcomes From Cognitive Interviews With Low-Income Adults

OBJECTIVE

This investigation sought to identify the physical activity (PA) terms and concepts that are best understood by low-income adults.

DESIGN

This was a cross-sectional study using semistructured cognitive interviews that employed retrospective verbal probing techniques.

SETTING

Interviews were conducted in Expanded Food and Nutrition Education Program (EFNEP) sites in New Jersey, Tennessee, and Washington.

PARTICIPANTS

A convenience sample of 57 adults participating in or eligible for participation in EFNEP.

PHENOMENON OF INTEREST

Participants' interpretations and conceptualizations of PA concepts and terms.

ANALYSIS

Template and constant comparative analysis.

RESULTS

Participants interpreted many PA terms and concepts in unintended ways. Exercise was the term that came closest to conveying moderate to vigorous PA. Terms used to describe muscle-strengthening activities were mostly understood. Intentional engagement in extra activities was difficult for participants to conceptualize despite multiple tested wordings; making small changes to be active came closest to conveying this concept. Participants' comprehension of the PA terms differed by their PA and literacy levels.

CONCLUSIONS AND IMPLICATIONS

Nutrition educators should be mindful of the terminologies they used in communicating messages and assessing PA behaviors to EFNEP participants or similar populations.

Perceived Environmental Barriers and Behavioral Factors as Possible Mediators Between Acculturation and Leisure-Time Physical Activity Among Mexican American Adults

BACKGROUND

The association between acculturation and physical activity (PA) among Mexican American (MA) adults is not understood. This study assessed potential mediating factors that may explain these associations among 75 healthy MA adults [age: 37.5 (9.3) y; 65.3% female].

METHODS

Secondary data analysis using hierarchical logistic regression examined whether perceived environmental barriers, social support, and intention to exercise potentially mediated relationships between acculturation level, and total and leisure-time moderate to vigorous PA (MVPA). Data were collected via questionnaire.

RESULTS

Most participants (67%) reported lower average household monthly incomes ($0-$3000), completed some college or obtained a college degree (64.4%), and were first generation immigrants (59%). Acculturation was associated with greater odds of engaging in total MVPA [odds ratio (OR) = 1.7; 95% confidence interval (CI), 1.2-2.4] and leisure-time MVPA (OR = 1.6; 95% CI, 1.1-1.2). Perceived environmental barriers were associated with greater odds of engaging in both total and leisure-time MVPA (OR = 4.3; 95% CI, 2.1-5.8 and OR = 5.5; 95% CI, 2.0-7.0, respectively), and social support was associated with greater odds for total MVPA (OR = 3.7; 95% CI, 1.1-6.4).

CONCLUSIONS

Results provide preliminary evidence for mediating factors that may explain the relationship between acculturation level and PA among MA adults. Contradicting prior evidence, results suggest that PA engagement, despite perceived environmental barriers, is possible among MA adults having stronger social support.

Feasibility of a Latin Dance Program for Older Latinos With Mild Cognitive Impairment

This study investigates the feasibility of a Latin dance program in older Latinos with mild cognitive impairment (MCI) via a feasibility mixed methods randomized controlled design. Spanish-speaking older Latinos (N = 21, 75.4 [6.3] years old, 16 females/5 males, 22.4 [2.8] Mini-Mental State Examination [MMSE] score) were randomized into a 16-week dance intervention (BAILAMOS) or wait-list control; the control group crossed over at week 17 and received the dance intervention. Feasibility was determined by assessing reach, retention, attendance, dance logs, and postintervention focus groups. Reach was 91.3% of people who were screened and eligible. Program retention was 95.2%. The dropout rate was 42.8% (n = 9), and attendance for all participants was 55.76%. The focus group data revealed 4 themes: enthusiasm for dance, positive aspects of BAILAMOS, unfavorable aspects of BAILAMOS, and physical well-being after BAILAMOS. In conclusion, older Latinos with MCI find Latin dance as an enjoyable and safe mode of physical activity.

Impact of Latin Dance on Physical Activity, Cardiorespiratory Fitness, and Sedentary Behavior Among Latinos Attending an Adult Day Center

Objective: The aim of this study was to determine whether a Latin dance program with sedentary behavior information would have an impact on physical activity, cardiorespiratory fitness (CRF), and sedentary behavior among older Latinos attending an adult day center (ADC). Method: Participants ( N = 21, 75.4 ± 6.3 years old, Mini-Mental State Examination [MMSE] score = 22.4 ± 2.8) were randomized into a dance or wait-list control group. Participants wore an accelerometer and inclinometer and completed a sedentary behavior questionnaire, and a nonexercise equation was used to calculate CRF. Results: Findings indicate small to medium effect sizes in the desired direction during midpoint of the intervention for physical activity, sedentary behavior–related outcomes, CRF, and self-reported sedentary behavior in the dance group; however; dance participants did not maintain that trajectory for the remaining 2 months of the intervention. Discussion: Future studies may consider implementing behavioral strategies during midpoint of the intervention to encourage participants attending an ADC to maintain physical activity and sedentary behavior changes.

Interrelationships of physical activity in different domains: Evidence from the Geographic Research on Wellbeing (GROW) study

Research has rarely distinguished between non-work (NW) and work (W) active transport (AT) or investigated relationships to other domains of physical activity ([PA], like leisure time [LTPA] or work [WPA]). We investigated correlates of AT by employment status, accounting for LTPA and WPA, in a population-based sample of California mothers (N=2906) in the Geographic Research on Wellbeing (GROW) study (2012-2013). AT was measured by the National Household Travel Survey. LTPA was measured using the Stanford Leisure-Time Activity Categorical Item. WPA was measured with the Stanford Brief Activity Survey. Most employed mothers (53%) worked in sedentary jobs, and few (<10%) used NWAT or WAT. Over 20% of unemployed mothers used NWAT, although LTPA levels were similar to employed mothers. Multiple regression models found employed and unemployed with low education and income, and unemployed African American or Latina immigrant mothers had higher odds of using NWAT. Younger employed and unemployed mothers, and unemployed who had ≥4 children or had "light" LTPA had lower odds of using NWAT. Multiple regression models demonstrated that low education or income employed mothers, African American mothers, those who worked part time, and those with relatively low LTPA had higher odds of using WAT, while younger women had lower odds of using WAT, compared with reference groups (ps<0.05). WPA was associated with WAT in unadjusted models, but not in adjusted models. Different AT patterns were seen for employed vs unemployed women, but women who used AT did so for most trips. LTPA was associated with NWAT among unemployed mothers and with WAT among employed mothers. Most women were underactive across all domains, suggesting no compensatory effect of PA done in one domain reducing PA done in another domain, with few meeting minimal guidelines. Policy and practice strategies should support infrastructure to encourage a variety of domains of PA.

Regular Latin Dancing and Health Education May Improve Cognition of Late Middle-Aged and Older Latinos

Disparities exist between Latinos and non-Latino Whites in cognitive function. Dance is culturally appropriate and challenges individuals physically and cognitively, yet the impact of regular dancing on cognitive function in older Latinos has not been examined. A two-group pilot trial was employed among inactive, older Latinos. Participants (N = 57) participated in the BAILAMOS^© dance program or a health education program. Cognitive test scores were converted to z-scores and measures of global cognition and specific domains (executive function, episodic memory, working memory) were derived. Results revealed a group × time interaction for episodic memory (p < .05), such that the dance group showed greater improvement in episodic memory than the health education group. A main effect for time for global cognition (p < .05) was also demonstrated, with participants in both groups improving. Structured Latin dance programs can positively influence episodic memory, and participation in structured programs may improve overall cognition among older Latinos.

Parent's Physical Activity Associated With Preschooler Activity in Underserved Populations

INTRODUCTION

In the U.S., children from low-income families are more likely to be obese. The impact of parent modeling of physical activity (PA) and sedentary behaviors in low-income American ethnic minorities is unclear, and studies examining objective measures of preschooler and parent PA are sparse.

METHODS

This cross-sectional study examined 1,003 parent-child pairs who were of low income, largely Latino and African American, and living in one of two geographically disparate metropolitan areas in the U.S. Parents and children wore GT3X/GT3X+ accelerometers for an average of >12 hours/day (7:00am-9:00pm) for 1 week (September 2012 to May 2014). Analysis occurred in 2015-2016.

RESULTS

About 75% of children were Latino and >10% were African American. Mean child age was 3.9 years. The majority of children (60%) were normal weight (BMI ≥50th and <85th percentiles), and more than a third were overweight/obese. Children's total PA was 6.03 hours/day, with 1.5 hours spent in moderate to vigorous PA (MVPA). Covariate-adjusted models showed a monotonic, positive association between parent and child minutes of sedentary behavior (β=0.10, 95% CI=0.06, 0.15) and light PA (β=0.06; 95% CI=0.03, 0.09). Child and parent MVPA were positively associated up to 40 minutes/day of parent MVPA, but an inverse association was observed when parental MVPA was beyond 40 minutes/day (p=0.002).

CONCLUSIONS

Increasing parental PA and reducing sedentary behavior correlate with increased PA-related behaviors in children. However, more work is needed to understand the impact of high levels of parental MVPA on the MVPA levels of their children.

Physical Activity and Incident Hypertension in African Americans: The Jackson Heart Study

There is limited empirical evidence to support the protective effects of physical activity in the prevention of hypertension among African Americans. The purpose of this study was to examine the association of physical activity with incident hypertension among African Americans. We studied 1311 participants without hypertension at baseline enrolled in the Jackson Heart Study, a community-based study of African Americans residing in Jackson, Mississippi. Overall physical activity, moderate-vigorous physical activity, and domain-specific physical activity (work, active living, household, and sport/exercise) were assessed by self-report during the baseline examination (2000-2004). Incident hypertension, assessed at examination 2 (2005-2008) and examination 3 (2009-2013), was defined as the first visit with systolic/diastolic blood pressure ≥140/90 mm Hg or self-reported antihypertensive medication use. Over a median follow-up of 8.0 years, there were 650 (49.6%) incident hypertension cases. The multivariable-adjusted hazard ratios (95% confidence interval) for incident hypertension comparing participants with intermediate and ideal versus poor levels of moderate-vigorous physical activity were 0.84 (0.67-1.05) and 0.76 (0.58-0.99), respectively (P trend=0.038). A graded, dose-response association was also present for sport/exercise-related physical activity (Quartiles 2, 3, and 4 versus Quartile 1: 0.92 [0.68-1.25], 0.87 [0.67-1.13], 0.75 [0.58-0.97], respectively; P trend=0.032). There were no statistically significant associations observed for overall physical activity, or work, active living, and household-related physical activities. In conclusion, the results of the current study suggest that regular moderate-vigorous physical activity or sport/exercise-related physical activity may reduce the risk of developing hypertension in African Americans.

Factors associated with leisure time physical activity among ELSA-Brasil participants: Ecological model

The main objective of the study was identify the prevalence and factors associated with leisure time physical activity (LTPA) in adult participants of the Longitudinal Study of Adult Health (ELSA-Brasil). The LTPA was measured using the International Physical Activity Questionnaire (IPAQ), long version. A hierarchical ecological model was built with the possible factors associated with LTPA distributed across blocks. We estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) using logistic regression. In men, being more educated, having a high family income, living in environments with conditions and opportunities for PA, being retired and being overweight were positively associated, while current smoking, obesity and abdominal obesity were associated negatively with the LTPA. Among women, being over 60years old, being more educated, having a high family income, living in an environment with conditions and opportunities for PA practice and being retired were positively associated, while being overweight, obese and having abdominal obesity were associated negatively with the LTPA. The proposed ecological model explains the LTPA through the social, physical and personal environment and highlights gender differences in physical activity.

Differences in neighborhood social cohesion and aerobic physical activity by Latino subgroup

Previous research has examined the role of neighborhood social cohesion in physical activity outcomes; however, less is known about this relationship across Latino subgroups. The purpose of our study was to examine the association between neighborhood social cohesion and aerobic leisure-time physical activity (LTPA) among Latino adults and to determine whether these associations differ by Latino subgroup. We used cross-sectional 2013-2014 National Health Interview Survey (NHIS) data on Latinos originating from 5 countries/regions (i.e., Latinos of Puerto Rican, Mexican/Mexican-American, Cuban/Cuban-American, Dominican and Central or South American origin) aged ≥18 years (n=11,126). Multivariable logistic regression models were used to estimate associations between self-reported neighborhood social cohesion and meeting aerobic LTPA guidelines. Models were adjusted for age, sex, education, and acculturation. We also investigated whether associations varied by Latino subgroup. In adjusted models for all Latino adults, compared with those reporting low social cohesion, individuals who reported high social cohesion (Odds Ratio [OR]: 1.33; 95% Confidence Interval [CI]: 1.17-1.52) were significantly more likely to meet the aerobic physical activity guideline. When stratified by Latino subgroups, among Mexican/Mexicans-Americans (OR: 1.39; 95% CI: 1.16, 1.66) and Cuban/Cuban Americans (OR: 1.73; 95% CI: 1.00, 2.97) high social cohesion was associated with meeting the aerobic activity guideline. Among Dominicans, those who reported medium social cohesion (OR: 0.52, 95% CI: 0.29, 0.93) were less likely to meet the aerobic activity guideline. When examining aerobic physical activity outcomes in the Latino population, the role of neighborhood social cohesion and the variability among Latino subgroups should be considered.

Using Qualitative Methods to Understand Physical Activity and Weight Management Among Bangladeshis in New York City, 2013

INTRODUCTION

South Asians experience high rates of cardiovascular disease and type 2 diabetes, coupled with low rates of reported physical activity. We report findings from a qualitative sub-study that was conducted in 2013 among Bangladeshi immigrants in New York City to understand factors that affect physical activity practices and weight management in this community.

METHODS

Qualitative study participants were recruited from community-based settings. Sex-specific focus groups were conducted by trained community health workers. Proceedings were audio-recorded for translation and transcription and coded using a constant comparative approach. Data were coded using Atlas.ti software.

RESULTS

Six focus groups were completed with a final sample of 67 participants (63% male, 37% female). Mean participant age was 42 years; mean years of residence in the United States was 12. Key themes that emerged were beliefs about modesty and sex-separated facilities that may prevent women from engaging in physical activity. Distinctions were made between men and women about what constitutes exercise versus physical activity; religious prayer was considered to be health-promoting because of the movement involved. Other important themes that emerged were cultural dietary practices and evolving conceptions of healthy weight.

CONCLUSION

Tailored interventions that take into account the cultural context of this growing community are needed. Findings may also provide insight into barriers to health promotion experienced by other US Muslim communities, which are growing rapidly.
