RESUMEN
INTRODUCTION: The present study investigated a model on how neighborhood walkability influences individual's active travel behavior, which in turn is associated with overall health status among Asian Americans. Given that English proficiency uniquely represents racial/ethnic minorities' ability to access resources and benefits in the host society, we also examined the moderating effects of English proficiency in the relationship. METHODS: Using data from the Asian American Quality of Life Survey (N= 1,447), Structural Equation Modeling (SEM) was conducted to examine the proposed mediation model of active travel in the relationship between neighborhood walkability and health. The moderating effect by English proficiency was tested using a multiple-group analysis. RESULTS: For the entire sample, neighborhood walkability was significantly associated with a higher level of active travel (ß = .269, p < .001). However, the mediation effect of active travel was not significant (indirect effect = .004, p = .111, 95% bias-corrected CI = -.003 - .026). The results of the multiple group analysis showed that the neighborhood walkability was positively associated with active travel for both the English proficiency group (ß =.329, p < .001) and the group with limited English proficiency (ß =.201, p < .001). However, the mediation effect of active travel on health status was only significant in the English proficiency group (ß = .110, p < .05), indicating that active travel influenced by the neighborhood walkability was positively associated with better health status only for the English proficiency group. CONCLUSIONS: Our findings add to the growing literature on the influence of the neighborhood walkability on individual's active travel and health status. In addition, findings provide implications for tailored interventions to promote Asian Americans' health with respect to English proficiency.
RESUMEN
Ensuring accessibility to necessary services is critical for older adults. However, there often exist spatial disparities in the levels of accessibility to services. Because the application of Geographic Information System (GIS) has gained attention in the gerontology field, we used spatial analysis to identify communities of concern for older adults from the perspective of accessibility. We defined the communities of concern based on the proportion of older adults and the level of accessibility to health, social, and daily services via two specific modes of transportation-walking and public transit. Our findings show that newly developed communities tend to have less accessibility to necessary services, and aging communities are randomly distributed across the city. Our results call for interdisciplinary collaboration, between urban planning and gerontology professionals, to better understand the spatial pattern of aging communities and its implication for properly addressing the mobility needs of older adults in the communities.

Although dental care is an essential component of comprehensive health care, a substantial proportion of the U.S. population lacks access to it. Disparities in dental care are most pronounced in racial/ethnic minority communities. Given the rapid population growth of Asian Americans, as well as the growing attention of neighborhood-level effects on health care use, the present study examines how individual-level variables (i.e., age, gender, marital status, ethnicity, education, place of birth, length of stay in the U.S., dental insurance, and self-rated oral health) and neighborhood-level variables (i.e., poverty level, density of Asian population, dentist availability, and Asian-related resources and services) contribute to predicting the use of preventive dental care in a sample of Asian Americans in Austin, TX. This study adds to the growing literature on the effect of neighborhood-level factors on health care as sources of disparities. Those living in the Census area with higher level of available dentists were more likely to use preventive dental care services. Findings suggest the importance of the location (proximity or accessibility) to dental clinics. In a planning perspective for health care policy, identifying the neighborhood with limited healthcare services could be a priority to diminish the disparity of the access.

In the United States, per capita vehicle miles traveled (VMT) displayed a general declining trend in the new millennium. This paper focuses on identifying the factors that drove the recent VMT trend. Using sample data from the 2001 and 2009 National Household Travel Surveys (NHTS), this study investigated differences in travel patterns by age groups over time and explored factors associated with the recent decrease in per-capita VMT. The study results show that the daily auto mileage and number of auto trips significantly decreased in 2009, although the change was uneven across different age groups. Increased travel by public transit and walking and biking, along with urbanization efforts, partly explained the recent decrease in automobile use. The findings also suggest that population-specific strategies such as improving public transit services for younger people and upgrading walking facilities for the elderly may help reduce automobile travel demand. In addition, applications of information and communication technologies (ICTs) can offer promising alternatives to automobile travel.
