| contents | There is limited understanding of how dietary behaviors cluster together and influence cardiometabolic health at a population level in Puerto Rico. Data availability is scarce, particularly outside of urban areas, and is often limited to non-probability sample (NPS) data where sample inclusion mechanisms are unknown. In order to generalize results to the broader Puerto Rican population, adjustments are necessary to account for selection bias but are difficult to implement for NPS data. Although Bayesian latent class models enable summaries of dietary behavior variables through underlying patterns, they have not yet been adapted to the NPS setting. We propose a novel Weighted Overfitted Latent Class Analysis for Non-probability samples (WOLCAN). WOLCAN utilizes a quasi-randomization framework to (1) model pseudo-weights for an NPS using Bayesian additive regression trees (BART) and a reference probability sample, and (2) integrate the pseudo-weights within a weighted pseudo-likelihood approach for Bayesian latent class analysis, while propagating pseudo-weight uncertainty into parameter estimation. A stacked sample approach is used to allow shared individuals between the NPS and the reference sample. We evaluate model performance through simulations and apply WOLCAN to data from the Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic Disease Trends (PROSPECT). We identify dietary behavior patterns for adults in Puerto Rico aged 30 to 75 and examine their associations with type 2 diabetes, hypertension, and hypercholesterolemia. Our findings suggest that an out-of-home eating pattern is associated with a higher likelihood of these cardiometabolic outcomes compared to a nutrition-sensitive pattern. WOLCAN effectively reveals generalizable dietary behavior patterns and demonstrates relevant applications in studying diet-disease relationships. |
