Oral health and access to dental care among older homeless adults: results from the HOPE HOME study

Abstract

Objectives: To describe the prevalence of and factors associated with oral health measures in a sample of older homeless adults in Oakland, CA.

Methods: We conducted a cross-sectional analysis of data from a population-based study of 350 homeless adults aged ≥50 in which trained researchers conducted structured interviews using validated questions regarding sociodemographics, health-related behaviors, healthcare utilization, and health status. We assessed self-reported tooth loss, oral pain, and unmet need for dental care. We used multivariable logistic regression to examine factors associated with missing half or more teeth.

Results: Over half 201/350 (57.4 percent) of participants were missing at least half of their teeth. Half 191/350 (54.6 percent) reported oral pain in the past 6 months; 101/350 (28.9 percent) reported that oral pain prevented them from eating and 73/350 (20.9 percent) reported that pain prevented sleeping. Almost half, 141/350 (40.3 percent), had not seen a dentist in over 5 years, and over half 190/350 (54.3 percent) reported being unable to obtain needed dental care. In multivariate models, increased age (AOR = 1.09, 95 percent CI 1.04-1.14), moderate-to-high risk alcohol use (AOR = 2.17, CI = 1.23-3.84), moderate-to-high risk cocaine use (AOR = 1.72, CI = 1.03-2.88), and ever smoking (AOR = 2.87, CI = 1.59-5.18) were associated with an increased odds of having lost half or more teeth.

Conclusions: Tooth loss and oral pain are highly prevalent in older homeless adults. Increasing age, alcohol, drug, and tobacco use are associated with tooth loss.
