Journal of Physical Activity and Health, 2011, 8, 429 -435 © 2011 Human Kinetics, Inc. Correlates of Physical Activity Among Hispanic Adults Timothy J. Bungum, Melva Thompson-Robinson, Sheniz Moonie, and Monica A.F. Lounsbery Background: Health behaviors of minority populations, including Hispanics, are important from a public health perspective because this subpopulation is growing and health behaviors of this subgroup are understudied. Physical activity is a component of healthy lifestyles and Hispanics have been shown to be less active than are Caucasians. It will be necessary to know correlates of physical activity to enhance the physical activity of this group. Recently, the importance of environmental and cultural factors has been recognized as correlates of physical activity behavior. The purpose of this study was to identify environmental and cultural correlates of physical activity among Hispanic adults. Methods: A 52-item telephone survey was employed to assess physical activity and its potential correlates. Results: The sample included 175 females and 156 males. Respondent ages ranged from 18 to 82 years (x = 38.39 ± 15.0). Approximately 20% of respondents were assigned to a “higher physical activity” group. Predictors of being in this group were having supportive environments, being acculturated, attending some college, and age. Conclusions: Providing environmental supports may be an effective strategy to enhance physical activity levels of adult Hispanics. Older Hispanics, those with lower educational attainments and those of lower acculturation should be targeted for intervention. Keywords: health behavior, physical activity Despite overwhelming evidence and widespread knowledge of the health benefits associated with regular participation in physical activity,1 the majority of American adults are not physically active at levels that produce health benefits.2 Recent data indicates that only about 15% of adult Americans perform recommended amounts of physical activity, while 40% of adults participate in no leisure time physical activity.3 Minority group members are especially inactive,4 including Hispanic-Americans.5,6 Important health benefits of regular physical activity include decreases in the risks of diabetes, obesity, and colon cancer, as well as lowering overall death rates.3 Physical activity also increases lean muscle mass and decreases body fat, both of which are important components of weight control regimens.7 Pursuant to the low physical activity rates among Hispanics, it is not surprising that members of this group suffer from hypokinetic diseases, such as diabetes, at rates higher than those of other ethnic groups.8 The Hispanic population is important from a public health perspective because it is America’s largest and fastest growing minority group.9 Despite the size and growth of the Hispanic population this group’s health habits are understudied.10 It is however known that Hispanics have body mass indices (BMIs) that are higher than those of whites.9 Bungum is with the Dept of Health Promotion, University of Nevada, Las Vegas. Thompson-Robinson and Moonie are with the Dept of Environmental and Occupational Health, University of Nevada, Las Vegas. Lounsbery is with the Dept of Sports Education Leadership, University of Nevada, Las Vegas. A first step to increasing physical activity among members of this subpopulation is to identify correlates of that behavior.11 Physical activity correlates have typically been divided into 4 categories: demographic, psychological, social/cultural, and environmental.11 Of these, environmental influences are the least studied across all populations.12 At least among Caucasians, environmental factors such as walkable destinations; safety from traffic, dogs, and other people; and the presence of sidewalks tend to be stronger predictors of moderately intense physical activity than are psychosocial and demographic variables, which are stronger predictors of vigorous physical activity and exercise.13 Accordingly, a position taken by the CDC suggests that environmental factors might be key to increasing moderately intense physical activities, including utilitarian physical activity (UPA), at the population level.14 UPA is physical activity that is done in the context of performing activities of daily living such as walking to work, a restaurant or a store. The paucity of research addressing environmental correlates of physical activity among Hispanics has been expressed in the literature.15 However, 2 studies were located. One large study assessed the association of the physical environment and exercise (planned physical activity) among Hispanic women from 3 states and it showed no association between those variables.16 Another study found no relationship between exercise and safety.10 This seeming lack of attention to environmental influences may partially explain why there has been limited success in promoting PA.3,17 Another variable that may influence physical activity behavior is culture. A trend toward less healthy behaviors 429 430 Bungum et al has been observed among Hispanics as they become more acculturated. A typical pattern for Hispanics is greater alcohol abuse, tobacco use, and less healthy diets as members of this group become more acculturated.18 However, exercise counters this trend, as it tends to increase with acculturation among Hispanics.10,18,19 It should be noted that exercise is defined as “planned physical activity done for the purpose of enhancing or maintaining some aspect of physical fitness.” 20 This presents a challenge for physical activity practitioners because exercise is usually done during leisure time, is often the purview of the highly educated and those whose lifestyles afford leisure time.21 Because Hispanics, as a group carry busy work schedules13 and are also less apt to pursue higher education than are other ethnic groups,22 promoting other types of physical activity, such as UPA to this group may be important. Promoting UPA is sensible to Hispanics because people doing this type of physical activity complete an activity of daily living while simultaneously receiving benefits from physical activity. Another attractive feature of UPA is that it is usually done at moderate intensities,13,23 and people are more apt to persist with these types of physical activity than they are with more vigorous forms.13 Further, there is some evidence that exercise is undervalued by Hispanic cultures.24 History also provides rationale for promoting UPA. Exercise has been promoted for over 30 years with little improvement at the population level.3 This suggests that telling people to be active in their free time because it will result in healthy outcomes is not particularly effective, or that effective and efficient exercise promoting programs remain undiscovered. Because leisure time physical activity is an infrequent pursuit among Hispanics18,25 UPA is especially important for this group. A challenge with increasing UPA is that much of it has been engineered out of the lives of Americans. Whether this type of physical activity can be reintroduced into the lives of a large proportion of Americans is open to debate. However, communities such as Tyson’s Corner, VA, Celebration, FL, and Portland, OR are amending zoning laws and providing incentives for environmental changes to their communities that are supportive of physical activity.26,27 Accordingly, purposes of this study were to determine whether Hispanic adult’s perceptions of neighborhood environmental characteristics, and acculturation are predictive of self-reported physical activity behavior. Methods A telephone survey using random digit dialing targeted Hispanic citizens aged 18 years and older living in Las Vegas, Nevada. All phone calls were made from a university-based center by trained interviewers. Calls targeted zip codes that are known to have high proportions of Hispanic residents. Approximately 77% of participants in this study lived in 1 of 5 zip code areas. The prevalence of Hispanic residents in these locales ranged from 33.4% to 69.2%. All calls were placed Mondays through Fridays from 10:00 AM to 7:00 PM, and occurred from mid-April through mid-June of 2007. Upon the phone being answered the interviewer explained that a survey assessing health-related behaviors was being conducted. As described elsewhere28 a procedure was used to objectively identify a telephone sample. If the person answering the phone indicated that there was at least 1 adult Hispanic in the household, it was requested that the person who was at least 18 years of age and had most recently celebrated his or her birthday respond to questions regarding their physical activity, diet, and other health behaviors. Potential respondents were informed that the interview would take about 15 minutes. Participants were also told that they could refuse to answer any question, and could end the call at any time. Potential participants were additionally made aware that there was minimal risk associated with involvement in the survey because the interview was being conducted anonymously. The interviewer disclosed that there were no direct benefits to the respondent, but that the information gleaned from the interview could be used to create programs that may enhance the health of Hispanics living in or near Las Vegas. Only 1 person per phone number was questioned and a maximum of 3 attempts per phone number were made. Participants had the option of having the survey conducted in English or Spanish. Those selecting to be interviewed in English were classified as “higher acculturation” and those choosing Spanish were labeled as “lower acculturation.” While there are more comprehensive methods of assessing acculturation10 it is often defined on the basis of language preference.18 The assessment instrument was a 52-item questionnaire that had been approved by the university’s Institutional Review Board. Respondents reported their readiness for, and current global physical activity by selecting the 1 statement that best described their recent physical activity behavior. The choices were 1) no regular physical activity and no intention to begin; 2) no current physical activity but plan to begin within 6 months; 3) trying to be physically active, but that such activity was infrequent; 4) vigorous physical activity less than 3 times per week; 5) moderate physical activity less than 5 times per week; 6) moderate physical activity 5 or more times per week or; 7) vigorous physical activity 3 or more times per week. This item has been used in other studies and has been shown to have adequate reliability (Kappa = .78)29 and concurrent validity with a 7-day recall of physical activity.30 Respondents selecting numbers 1 or 2 were classified as “lower physical activity.” Because physical activity behavior tends to be overestimated,31 those selecting response number 3 (“trying to be physically active, but that such physical activity is infrequent”) were also labeled as being lower physical activity. Respondents who described their physical activity behavior by selecting numbers 4, 5, 6, or 7 were labeled as “higher physical activity.” Neighborhood environments were assessed by 6 items. These specific items were selected because they Environmental and Cultural Correlates 431 have been shown, or hypothesized to influence physical activity. Specific items assessed the presence of neighborhood sidewalks, the nearness of parks and recreation facilities, the perceived prevalence of neighborhood crime, heaviness of neighborhood motorized traffic, whether neighbors could be trusted, the presence of unleashed dogs, and the perception that a grocery store was within walking distance.32 Response choices to the items that assessed the availability of sidewalks and public recreation facilities, the trustworthiness of neighbors and the ability to easily walk to a grocery store were “yes” or “no.” Items that measured the pleasantness of the neighborhood, the presence of unleashed dogs and neighborhood safety were measured on 4-point Likert type scales. These items had endpoints of “not at all pleasant/very pleasant; not a problem at all/a problem, and not at all safe and extremely safe,” respectively. Those items that were measured on 4-point scales were dichotomized. For instance, when measuring neighborhood pleasantness, “not at all pleasant” and not pleasant” were combined as were “pleasant” and “very pleasant.” Respondents selected “heavy, moderate or light” to describe neighborhood traffic. Test-retest reliability of these scales have been assessed by others and have been found to be between .42 and .74.33 Information regarding the age, gender, and educational attainment of participants were also collected, as these factors have been shown to influence physical activity.34–36 Educational attainment was dichotomized into groups of those who had attended at least some college, and those who had not. Other data were collected but were not used in this study. Information on mental health issues, HIV risks, tobacco use, health care behavior, health care insurance coverage, and recent dental care were also requested. Statistical Analysis Initial statistics were run to describe demographic characteristics of respondents. Factor analysis, which extracted components using principal component analysis with varimax rotation, was used to assess the construct validity of the neighborhood environmental characteristics. Items whose factor loading scores were > .40 became a component of that variable. This procedure produced 2 factors of the neighborhood environment. Four items (safety from crime, neighbor trustworthiness, unleashed dogs, and the heaviness of traffic) loaded on the factor “safety,” which explained 20.5% of the variance in the items that assessed environmental factors. The items that loaded on the other component, “supportive environment,” were the presence of sidewalks, the availability of public recreation areas (including parks), a nearby grocery store, and the heaviness of motorized traffic, which loaded on both factors. Supportive environment explained 18.0% of the variance in the items that assessed environmental influences. Finally, logistic regression was used to identify predictors of being assigned to the physical activity groups. Variables in the regression models included supportive environment, environmental safety, acculturation, body mass index, educational attainment, gender, and age. The significance level for all analyses was set at P < .05. Results A total of 331 eligible people completed the phone interview. The cooperation rate was 60% (331/551). This rate was calculated by dividing the number of completed interviews by the number of calls that produced an eligible participant. Slightly more females (n = 175; 52.8%) than males (n = 156; 47.2%) completed the survey. The mean age of participants was 38.4 years (SD = 15.0) and ranged from 18 to 82 years. Approximately one-third (n = 117; 35.4%) of the sample were of normal BMI, 39.4% (n = 130) were overweight and 23.7% (N = 78) were obese. A small proportion were college graduates (n = 19; 5.7%) or had completed some college (n = 25; 7.6%), and about one-half of the sample was married, (n = 165; 50.3%). Slightly more than one-half of respondents (50.8%) elected to have the interview conducted in Spanish, and the remainder completed it in English. The proportion of participants who rated their health as excellent, very good, good, fair, or poor were 10.3, 11.8, 40.3, 24.5, and 7.9% respectively. Most respondents (75.0%) had not smoked 100 cigarettes in their lifetimes and less than one-half (44.7%) were employed. Physical activity behavior data are presented in Table 1. Approximately 20% of respondents (n = 65) were assigned to the “higher physical activity” group, while 266 (80%) were categorized as “lower physical activity.” Neighborhood perceptions are presented in Table 2. Most variables were scored favorably as they relate to participation in physical activity. A majority of respondents reported the presence of sidewalks and nearby public recreation facilities, and over three-fourths could easily walk to a grocery store. The logistic regression model that predicted assignment into higher and lower physical activity groups produced 4 significant independent variables. Age (P = .037), with the younger being more active, supportive destinations (OR = 1.37; P = .024), attending at least some college (OR = 3.50; P = .003), and acculturation as measured by language preference (OR = 15.2; P < .001), with those responding in English being more active, predicted assignment to the higher active group. Environmental safety, gender, and BMI were not significant predictors of higher or lower physical activity. Results from this model are presented in Table 3. Discussion Perhaps this study’s most interesting finding, in the sense that it is changeable, is that having supportive destinations in one’s neighborhood predicted being assigned to the higher physical activity group. The items that comprised “supportive environment” included sidewalk availability, 432 Bungum et al Table 1 Current Physical Activity Behavior I do not exercise or walk and do not intend to start I do not exercise or walk but have been thinking about starting I am trying to walk or exercise regularly, or I walk or exercise infrequently I am doing vigorous exercise less than 3 times per week I have been doing moderately intense exercise 4 or fewer times per week for the past 6 months I have been doing moderately intense physical activity 5 or more times per week for the past 6 months I have been doing vigorous physical activity 3 or more times per week for less than 6 months I have been doing vigorous physical activity 3 or more times per week for more than 6 months n 52 44 170 30 15 5 5 10 % 15.7 13.3 51.4 9.1 4.5 1.5 1.5 3.0 Table 2 Neighborhood Characteristics % 82.8 61.0 77.8 14.8 21.3 42.3 52.1 71.9 Does neighborhood have your sidewalks (yes) Does your neighborhood have public recreation facilities (yes) Can you easily walk to a grocery store (yes) How would you rate your neighborhood as a place to walk?

This finding supports the notion that how we design and build our cities associates with the physical activity behavior of Hispanic Americans.17 This result is also in agreement with those who believe that sidewalks and parks are essential if physical activity is to be enhanced at the population level.37,38 The high reported prevalence of sidewalks in this study supports data which shows that Hispanics tend to live in walkable neighborhoods,39 which suggests that a portion of the physical activity in the current study was UPA. Additional evidence that our reported physical activity was likely UPA and not exercise, is that Hispanics have low rates of leisure time physical activity,16 exercise tends to be of low value to Hispanics15 and because supportive physical environments are more related to UPA than they are to exercise.40 Another finding of note is that acculturation associates with physical activity. This has been shown by others and suggests that those who are more acculturated, are more physically active. The strength of association of this finding (OR = 15.2), and because it is in agreement with the work of others,34,41,42 we believe that acculturation Environmental and Cultural Correlates 433 has a powerful influence on physical activity. It is clear that less acculturated Hispanics, and especially MexicanAmericans who are slower to acculturate to American ways than are other Hispanic groups, should be targets for intervention.18 Recreation facilities may also be important physical activity promoting supports for Hispanics, as there is some evidence, at least among African-American and White adolescents living in South Carolina, that those who live near facilities are more physically active than those who do not.43This suggests that building recreational facilities in Hispanic neighborhoods may increase physical activity among area residents. Because of the nature of how decisions are made about zoning, whether parks and sidewalks are built, and how heavily and fast automobile traffic will flow, it is likely that it will be necessary for people to be involved in the political processes that determine how cities and neighborhoods are built and evolve. It has been correctly predicted that making policy changes that effect the physical environment will be political and potentially controversial.26 Recently, the state of Virginia implemented new policies, that would among other things, make neighborhoods more walkable and bikable. As predicted, some developers have resisted these changes and claim that people want to live in places that are not supportive of physical activity. The characteristics that developers claim that people want include density and connectivity (eg, sprawling areas with many cul-desacs).26 Therefore concerned citizens and transportation authorities will likely need to educate citizens and advocate for neighborhoods that are favorable for physical activity, because others are equally vociferous in arguing for low density, low connectivity neighborhoods.44 Nearby grocery stores may be an especially important environmental factor in increasing physical activity levels because they are the most frequent destinations for people using UPA.33 The presence or nonpresence of nearby grocery stores is suggestive of built environments that are UPA friendly.45 Again, involvement in the political process may be necessary to influence zoning decisions that will allow residential and commercial property to be near one another. Nearby grocery stores may be especially important for Hispanics who are less likely to own cars than are members of other ethnicities.18 It is of note that the perception of neighborhood safety did not predict physical activity. This finding appears to be counterintuitive as one might expect that people would walk more in safer neighborhoods. However, 1 cross-sectional study has shown that those who reside in unsafe environments are more likely to walk or bike than people who report living in safer areas.46 It is probably not that walkers and bikers prefer dangerous environs, but that those who use UPA are more directly exposed to unsafe environments and are therefore more aware of their neighborhood’s dangers than are those who travel in motor vehicles through the same areas.10 This finding may also reflect the life situation of people who have no transportation choices other than walking or biking. Such people are sometimes referred to as “captive walkers.”46 Although environmental changes are no doubt important in efforts to increase physical activity, it is unlikely that the environment alone will be the “magic bullet” that motivates people to become more physically active.40 Interventions that promote physical activity will also likely be necessary before population level improvements in physical activity behavior will occur.44,47 This has led to the idea that to increase physical activity attention will need to be paid to “the 4 E’s.” The E’s are; 1) engineering, which will help create walkable neighborhoods; 2) enforcement, which will keep walkers and bicyclists safer from speeding traffic; 3) education, which will make people aware of the benefits and opportunities available for physical activity; and 4) encouragement, which will provide support for people to be physically active.13 There are several limitations of this study. Limitations include the self-reported nature of the data, although the instrumentation is widely used and has been tested for reliability and validity.33 In addition, because of the cross-sectional study design we cannot distinguish the temporal sequence of the relationships of physical activity and the assessed correlates. For example, we do not know if people who enjoy walking purposefully chose to live in areas that are supportive of that behavior, or if the environment provides the impetus for people to participate in physical activities. Because there is data that indicates that it is the environment that influences behavior rather than active people self-selecting to live in physical activity supportive environments,42 we believe that it is unlikely that temporal sequence is an issue in this study. It would also have been preferable to measure acculturation with more than the 1 item we used, language preference. Further, our sample was also limited to those who had telephones and were willing to respond to the questionnaire. However, our obesity data are similar to rates seen among Hispanics,48 suggesting that our sample is similar to the overall Hispanic population. It should be noted that findings from this study do not pertain to Hispanics living in other parts of the United States. However, this could also be viewed as a strength. The one large study that assessed the relationship of environmental factors with physical activity among Hispanic females included women from only North Carolina, Maryland, and Illinois.16 The current study was conducted in the West, which is home to the plurality of Hispanic-Americans and is the only region of the country where the proportion (24.3%) of Hispanics exceeds that of the national average (12.5%).49 Finally, an incomplete array of possible physical activity predictors were assessed in this study. In the future researchers should be alert for opportunities to study the effects of environmental changes on physical activity such as those that are now occurring in 434 Bungum et al Virginia. Studies that capture the effects of environmental changes on physical activity would allow researchers to establish temporal sequence and more clearly determine which environmental factors influence physical activity behaviors. Such information would be valuable to those attempting to increase physical activity among Hispanic-Americans and would provide data that would potentially strengthen arguments for building physical activity friendly communities.
