ALT Figure 2. Probability of latent class membership as a polynomial function of age for adults 18–65 years old. AUD = alcohol use disorder, PTSD = post-traumatic stress disorder. Results presented here are from those with at least one past year substance use, mood, anxiety, or post-traumatic stress disorders. The overall prevalence of any past-year disorder decreased across age (see Figure 1, Panel A, which depicts estimated prevalences in the entire sample), whereas, the relative prevalence increased with age for certain latent classes present here (among only those with a past year disorder, n = 11,279). #Comorbidities #LatentClassAnalysis
