Differences in Social Isolation and Its Relationship to Health by Rurality.

Social isolation is an urgent threat to public health. Meanwhile, health outcomes across multiple measures are worse in rural areas, where distance to neighbors is often greater and opportunities for social interaction may be scarcer. Still, very little research examines rural-urban differences in social isolation. This study addresses that gap by examining differences in social isolation by rurality among US older adults. Using Wave 2 of the National Social Life, Health, and Aging Project data (n = 2,439), we measured differences between urban and rural (micropolitan or noncore) residents across multiple dimensions of social isolation. We also conducted multivariable analysis to assess the associations between rurality, sociodemographic characteristics, and loneliness, overall and by rurality. Finally, we conducted multivariable analysis to assess the association between social isolation and self-rated health, adjusting for rurality. Compared to urban residents, rural residents had more social relationships and micropolitan rural residents were more likely to be able to rely on family members (95.8% vs 91.3%, P < .05). Micropolitan rural residents reported lower rates of loneliness than urban residents after adjusting for sociodemographic and health characteristics (b = -0.32, P < .05), whereas noncore rural, non-Hispanic black residents had a greater likelihood of reporting loneliness (b = 4.33, P < .001). Overall, noncore and micropolitan rural residents reported less social isolation and more social relationships than urban residents. However, there were differences by race and ethnicity among rural residents in perceived loneliness. Policies and programs to address social isolation should be tailored by geography and should account for within-rural differences in risk factors.

Nursing Home and Market Factors and Risk-Adjusted Hospitalization Rates Among Urban, Micropolitan, and Rural Nursing Homes.

Hospitalizations are common among long-stay nursing home (NH) residents, but the role of rurality in hospitalization is understudied. This study examines the relationships between rurality, NH, and market characteristics and NH quarterly risk-adjusted hospitalization rates of long-stay residents over 10 quarters (2011 Q2-2013 Q3). The longitudinal associations of NH and market factors and hospitalization rates were modeled separately on urban, micropolitan, and rural NHs using generalized estimating equation models and a fully interacted model of all NH and market characteristics with micropolitan and rural indicators to test significance of differences compared with urban NHs. In total, 14,600 unique NHs. Risk-adjusted hospitalization rates were calculated from 2011 to 2013 national Medicare claims and NH Minimum Data Set 3.0. Rurality was defined based on the 2010 Rural Urban Commuting Area codes. NH and market characteristics were extracted from Certification and Survey Provider Enhanced Reporting and Area Health Resources File. Over the study period, risk-adjusted hospitalization rates averaged 9.8% (standard deviation = 8.2%). No difference was found in the overall hospitalization rates of long-stay NH residents among urban, micropolitan, and rural NHs. Generalized estimating equation models show that urban NHs with higher percentages of Medicare and Medicaid residents and any nurse practitioner/physician assistant were associated with lower rates, but these associations were insignificant in rural settings. Higher registered nurse to total nurses ratio was only associated with lower hospitalization rates in urban settings. Higher median household income was associated with lower hospitalization rates in micropolitan and rural NHs. Rurality is not associated with hospitalization rates of long-stay residents, but NH and market factors (eg, payer distribution, staffing, and population income) may affect hospitalization differently in micropolitan/rural NHs than urban NHs. Future intervention on hospitalization should target factors unique to micropolitan/rural NHs which adopt strategies appropriate to their setting.

Examining Rural and Racial Disparities in the Relationship Between Loneliness and Social Technology Use Among Older Adults.

Loneliness, the subjective negative experience derived from a lack of meaningful companionship, is associated with heightened vulnerability to adverse health outcomes among older adults. Social technology affords an opportunity to cultivate social connectedness and mitigate loneliness. However, research examining potential inequalities in loneliness is limited. This study investigates racial and rural-urban differences in the relationship between social technology use and loneliness in adults aged 50 and older using data from the 2016 wave of the Health and Retirement Study (N = 4,315). Social technology use was operationalized as the self-reported frequency of communication through Skype, Facebook, or other social media with family and friends. Loneliness was assessed using the UCLA Loneliness scale, and rural-urban differences were based on Beale rural-urban continuum codes. Examinations of race focused on differences between Black/African-American and White/Caucasian groups. A path model analysis was performed to assess whether race and rurality moderated the relationship between social technology use and loneliness, adjusting for living arrangements, age, general computer usage. Social engagement and frequency of social contact with family and friends were included as mediators. The primary study results demonstrated that the association between social technology use and loneliness differed by rurality, but not race. Rural older adults who use social technology less frequently experience greater loneliness than urban older adults. This relationship between social technology and loneliness was mediated by social engagement and frequency of social contact. Furthermore, racial and rural-urban differences in social technology use demonstrated that social technology use is less prevalent among rural older adults than urban and suburban-dwelling older adults; no such racial differences were observed. However, Black older adults report greater levels of perceived social negativity in their relationships compared to White older adults. Interventions seeking to address loneliness using social technology should consider rural and racial disparities.
