We limited our analysis to those who were 65 years and older and answered to the 2012 experimental module on life-space (N=895; mean age=75.3; 59.4\% women). Life-space was assessed with the modified version of the UAB Study of Aging Life-Space Assessment, ranging nine zones: room, home, own property, immediate neighborhood, town, community, county, state, and region. A series of logistic regression models were used to estimate odds ratios for life-space constriction by sociodemographic and health characteristics. The results showed that 3.0\% and 6.7\% of older adults reported that they had never been to places beyond their home and own property/apartment building for the past four weeks, i.e. the critical boundaries in terms of social isolation. The significant factor associated with the life-space constriction within home, immediate neighborhood, and town was physical mobility limitation (OR: 1.18, 1.09, 1.11, respectively), while the constriction within county was associated with education level (OR: 0.91). Driving a car was negatively associated with the life-space constriction within own property/apartment building and home (OR: 0.48 and 0.22, respectively). Policy makers need to pay more attention to social and environmental factors influencing social isolation among older adults such as transportation options and social class disparity.}, keywords = {life-space, space constriction}, isbn = {2399-5300}, url = {https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6841504/}, author = {Moon Choi and Briana Mezuk} } @article {7979, title = {Trajectories of cognitive decline by driving mobility: evidence from the Health and Retirement Study}, journal = {International journal of geriatric psychiatry}, volume = {29}, year = {2014}, note = {24022894}, pages = {447-53}, publisher = {29}, abstract = {OBJECTIVE: The recent emphasis of the importance of aging in place has highlighted the role of transportation in health promotion over the life course. Driving cessation in later life is associated with numerous poor health outcomes including limitations in social and physical functioning and increased risk of mortality. However, little is known about the relationship between driving cessation and change in cognitive functioning in late life. This study examined the association between driving mobility and trajectories of cognitive functioning among older adults.; METHODS: Using data from six waves 1998-2008 of the Health and Retirement Study, trajectories of cognitive functioning were estimated over a 10-year period using longitudinal mixed effects models N=9,135 . Cognitive function was assessed with a modified version of the Telephone Interview for Cognitive Status. Driving status and health characteristics were assessed by self-report.; RESULTS: Older adults who did not drive (former and never drivers) at baseline had lower average cognitive scores compared with active drivers. Former drivers had accelerated cognitive decline over the subsequent 10years compared with active drivers (beta=-0.35, 95 Confidence Interval CI =-0.43 to -0.26) even after controlling for baseline cognitive functioning and health status. The transition to non-driving was associated with a faster cognitive decline among those who were driving at baseline (beta=-0.31, 95 CI=-0.40 to -0.22).; CONCLUSIONS: Older adults without driving mobility had poorer cognitive functioning at baseline and experienced accelerated cognitive decline relative to active drivers over follow-up.

Chi-square and t tests were used to assess differences between never and former drivers and between cohorts. Logistic regression was used to examine the predictors of having never driven. The driving status among older adults has improved over the past 15 years as the proportion of never drivers declined from 11 to 2 . However, nondriving has become more concentrated among ethnic minority women, and the gaps in education and net worth between former and never drivers widened over the 15 years.}, keywords = {Demographics, Health Conditions and Status, Other, Women and Minorities}, doi = {10.1177/0733464812441502}, url = {Go to ISI ://CCC:000324060300007http://www.sagepub.co.uk}, author = {Moon Choi and Briana Mezuk} }
