The Role of Stress in Understanding Differences in Sedentary Behavior in Hispanic/Latino Adults: Results From the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study

Elizabeth Vásquez, Garrett Strizich, Linda Gallo, Simon J. Marshall, Gina C. Merchant, Rosenda Murillo, Frank J. Penedo, Christian Salazar, Daniela Sotres-Alvarez, Benjamin A. Shaw, and Carmen R. Isasi

Background:

Chronic stress and/or lifetime traumatic stress can create a self-reinforcing cycle of unhealthy behaviors, such as overeating and sedentary behavior, that can lead to further increases in stress. This study examined the relationship between stress and sedentary behavior in a sample of Hispanic/Latino adults (N = 4244) from the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

Methods:

Stress was measured as the number of ongoing difficulties lasting 6 months or more and as lifetime exposure to traumatic events. Sedentary behavior was measured by self-report and with accelerometer. Multivariable regression models examined associations of stress measures with time spent in sedentary behaviors adjusting by potential confounders.

Results:

Those who reported more than one chronic stressor spent, on average, 8 to 10 additional minutes per day in objectively measured sedentary activities (P < .05), whereas those with more than one lifetime traumatic stressor spent (after we adjusted for confounders) 10 to 14 additional minutes in sedentary activities (P < .01) compared with those who did not report any stressors. Statistical interactions between the 2 stress measures and age or sex were not significant.

Conclusion:

Interventions aimed at reducing sedentary behaviors might consider incorporating stress reduction into their approaches.

Active or Sedentary? Objectively Measured Physical Activity of Latinos and Implications for Intervention

David X. Marquez, Eduardo E. Bustamante, Edward McAuley, and Dawn E. Roberts

Background:

Latinos have the lowest leisure-time physical activity (LTPA) rates. However, measurement of only LTPA might underestimate total physical activity. This study compares the objective physical activity of Latinos reporting high or low levels of LTPA and also compares gender differences.

Methods:

Data were obtained from 148 Latinos (n = 83 women, n = 65 men). Freedson cut points were employed to determine daily minutes of activity.

Results:

Latinos reporting high LTPA engaged in more daily minutes of vigorous and very vigorous activity than Latinos reporting low LTPA (P values < .05). There was no difference in daily minutes of moderate-intensity activity (P = .12), with both groups of Latinos meeting Centers for Disease Control and Prevention/American College of Sports Medicine guidelines. Men engaged in more daily minutes of moderate activity than women (P < .01).

Conclusions:

Many Latinos met physical activity guidelines even when reporting low levels of LTPA. Future studies should determine whether equivalent health benefits are achieved by meeting guidelines through LTPA and non-LTPA.

Isotemporal Analysis of the Association of Objectively Measured Physical Activity With Depressive Symptoms: Results From Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

Chad D. Rethorst, Ashley E. Moncrieft, Marc D. Gellman, Elva M. Arredondo, Christina Buelna, Shelia F. Castañeda, Martha L. Daviglus, Unab I. Khan, Krista M. Perreira, Daniela Sotres-Alvarez, and Mark Stoutenberg

Background:

The burden of depression among Hispanics/Latinos indicates the need to identify factors related to depressive symptoms. This paper examines the relationship of physical activity (PA) and sedentary behavior (SB) with depressive symptoms in Hispanic/Latinos.

Methods:

The Hispanic Community Health Study / Study of Latinos (HCHS/SOL) is a population-based, cohort study of Hispanic/Latinos in 4 United States metropolitan areas. Objectively measured PA was coded into: sedentary behavior (SB), light-intensity (LPA), moderate-intensity (MPA), and vigorous-intensity (VPA); and the Center for Epidemiological Studies Depression Scale-10 assessed depressive symptoms. Multiple regression analysis utilizing isotemporal substitution, adjusted for relevant covariates, examined PA as predictors of depressive symptoms.

Results:

Substitution of 1 hour of SB with VPA resulted in a significant decrease in depressive symptoms (β = –1.215, P = .021). Similar decreases were observed when VPA replaced LPA (β = –1.212, P = .021) and MPA (β = –1.50 P = .034). MPA and LPA were not associated with lower depressive symptoms.

Conclusions:

Previous research has focused on the relationship of MVPA on depressive symptoms. Our results suggest these constructs should be examined separately as they may have unique relationships with depressive symptoms. The association of SB with greater depressive symptoms confirms previous reports.

Reboot: Major League Soccer’s 2018 Relaunch of Chivas USA as the Los Angeles Football Club

R. Douglas Manning

The Los Angeles Football Club (LAFC) will begin play in 2018 as a new franchise in Major League Soccer (MLS). LAFC will replace Chivas USA as the second MLS franchise in the Los Angeles area. Chivas USA competed in 10 seasons of MLS, beginning with the 2005 season. Chivas USA was modeled after its parent organization, Club Deportivo Guadalajara (otherwise known as Guadalajara or Chivas Guadalajara) of the first-division Mexican League. MLS is highly regarded for its diversity initiatives, and Chivas USA was to focus on reaching the large Hispanic/Latino audience in the Los Angeles area. The club played alongside the Los Angeles Galaxy, one of MLS’s inaugural franchises, in the Home Depot Center (now StubHub Center) in Carson, California.

Physical and Social Contextual Influences on Children’s Leisure-Time Physical Activity: An Ecological Momentary Assessment Study

Genevieve F. Dunton, Yue Liao, Stephen Intille, Jennifer Wolch, and Mary Ann Pentz

Background:

This study used real-time electronic surveys delivered through mobile phones, known as Ecological Momentary Assessment (EMA), to determine whether level and experience of leisure-time physical activity differ across children’s physical and social contexts.

Methods:

Children (N = 121; ages 9 to 13 years; 52% male, 32% Hispanic/Latino) participated in 4 days (Fri.–Mon.) of EMA during nonschool time. Electronic surveys (20 total) assessed primary activity (eg, active play/sports/exercise), physical location (eg, home, outdoors), social context (eg, friends, alone), current mood (positive and negative affect), and enjoyment. Responses were time-matched to the number of steps and minutes of moderate-to-vigorous physical activity (MVPA; measured by accelerometer) in the 30 minutes before each survey.

Results:

Mean steps and MVPA were greater outdoors than at home or at someone else’s house (all P < .05). Steps were greater with multiple categories of company (eg, friends and family together) than with family members only or alone (all P < .05). Enjoyment was greater outdoors than at home or someone else’s house (all P < .05). Negative affect was greater when alone and with family only than friends only (all P < .05).

Conclusion:

Results describing the value of outdoor and social settings could inform context-specific interventions in this age group.
