Abstract: ObjectivesLoneliness is a significant public health concern associated with adverse mental and physical health outcomes in older adults. This study examined the nature and correlates of predominant loneliness trajectories in a nationally representative sample of older U.S. military veterans.MethodsParticipants included 2,441 veterans (mean age = 63, 8% female, 80% White) from the National Health and Resilience in Veterans Study, a 3-year longitudinal cohort study. Growth mixture modeling (GMM) was used to identify distinct trajectory classes of loneliness based on self-reported ratings. Multinomial logistic 3-step regression analyses examined potential psychosocial risk and protective factors associated with loneliness trajectories.ResultsGMM revealed 3 distinct loneliness trajectories: low-decreasing loneliness (61.2%), moderate-increasing loneliness (31.6%), and high-increasing loneliness (7.2%). Being married/partnered and perceiving a greater purpose in life emerged as protective factors against elevated levels of loneliness. Worse cognitive functioning was a risk factor for the moderate-increasing loneliness trajectory, while greater psychological distress and more adverse childhood experiences were risk factors for the high-increasing loneliness trajectory.DiscussionNearly 40% of older U.S. veterans exhibited trajectories characterized by moderate to high levels of loneliness, with both groups showing increases over time. Targeted interventions that promote social connectedness, enhance purpose in life, and address mental health concerns and early life adversities may help mitigate the negative health consequences associated with chronic loneliness in this vulnerable population.
