ABSTRACT
Background and Objectives: Loneliness is a major public health concern; however, limited research has examined the mechanisms contributing to racial/ethnic inequities in loneliness. Race/ethnicity has been hypothesized to be a distal factor influencing loneliness, and racial/ethnic inequities in loneliness may be attributable to socioeconomic factors (e.g., income and education). Our study seeks to confirm these hypotheses by examining mechanisms that contribute to racial/ethnic inequities in loneliness. In other words, if racial/ethnic differences in loneliness among older adults are mediated by income and education. Research Design and Methods: Data came from the Health and Retirement Study Leave-Behind Questionnaire, 2014-2016. Loneliness was measured by the UCLA 3-item loneliness scale. Race/ethnicity categories were White, Black, and Hispanic/Latino. The mediator variables were household income and education. Multivariable linear regression models were used to determine differences in loneliness by race/ethnicity. The Karlson-Holm-Breen (KHB) mediation method was used to determine if income and education mediated racial/ethnic differences in loneliness. Results: In models examining income and education together, a complete mediation was found between White and Black older adults, in that income and education completely mediated differences in loneliness between these groups. A partial mediation was found between White and Hispanic, and Black and Hispanic older adults. When examining income and education separately, we found that income solely accounted for racial/ethnic differences in loneliness compared to education. Discussion and Implications: Our study is the first to explicitly determine if socioeconomic factors mediate race/ethnicity differences in loneliness among a national sample of older adults. These findings illustrate that income may have greater proximate effects for loneliness among older adults in comparison to education. Additionally, these findings can inform evidence-based interventions to reduce loneliness among older adults. Interventions that enhance quality of life and provide opportunities for socialization for racialized low-income older adults may help decrease racial/ethnic inequities in loneliness.
ABSTRACT
Social isolation is associated with worse health; however, few studies have examined the health effects of isolation among African Americans. The purpose of this study is to evaluate associations between social isolation and self-rated physical and oral health from the National Survey of American Life, a nationally representative sample of African Americans. Social isolation was operationalized to reflect both objective isolation (lack of contact) and subjective isolation (lack of emotional closeness). Self-rated physical and oral health were regressed on objective and subjective isolation while controlling for marital status, gender, age, family income, education, and health behaviors. Poorer self-rated physical health was associated with objective isolation, while poorer self-rated oral health was associated with subjective isolation. This study contributes to the small literature of the impact of social isolation on health among African Americans; furthermore, it is the first to examine the relationship between isolation and self-rated oral health in this population.

BACKGROUND: Anxiety disorders are among the most prevalent psychiatric conditions worldwide, and the incidence of anxiety disorders among adults in the U.S. have increased over the last decade. Anxiety disorders can have debilitating effects on multiple areas of functioning and quality of life. Recently, social isolation has emerged as an important public health problem associated with worse health and well-being outcomes. Research on the connection between social isolation and mental health has found that multiple dimensions of social isolation may negatively impact mental health, but few inquiries have focused on the association between social isolation and anxiety. This study examined the relationships between multiple dimensions of social isolation and anxiety disorders in a nationally representative sample of adults aged 18 and older. METHODS: The sample includes 6082 individuals from the National Survey of American Life. This study examined whether three different dimensions of social isolation-subjective, interpersonal, and structural-were associated with 12-month and lifetime anxiety disorders (any anxiety disorder, posttraumatic stress disorder (PTSD), generalized anxiety disorder (GAD), panic disorder (PD), social anxiety disorder (SAD), and agoraphobia (AG). Logistic regressions were used to test the associations between the three social isolation variables and the anxiety outcomes. RESULTS: This study found that of the three dimensions of social isolation, subjective isolation was most consistently related to both lifetime and 12-month anxiety disorders. Those who were subjectively isolated had increased odds of meeting criteria for any anxiety disorder, PTSD, GAD, PD, and AG over the past 12 months and throughout their lifetimes. Structural isolation was negatively associated with lifetime and 12-month AG. CONCLUSIONS: Public health approaches should include mental health and primary care providers and need to target social isolation, especially subjective isolation, which may be key in preventing anxiety disorders and the worsening of anxiety disorders. Future public health research is needed on how and in what ways the differing dimensions of social isolation impact mental health.
