Objective: To examine whether risk tolerance is associated with adherence to oral hypoglycemic agents (OHAs). Methods: We performed a cross-sectional study among adult patients with type 2 diabetes mellitus (n = 308) presenting for routine out-patient visits, using validated questionnaires to estimate: risk preferences (risk-seeking, risk averse, risk neutral), motivation, self-efficacy, impulsivity, perception of the disease and of the interpersonal process of care, demographic and socioeconomic characteristics; computerized patient medical records to estimate disease severity and a computerized database for retrieval of medication adherence, 1 year before the interview. Adherence was estimated using prescription-based measures of proportion of days covered (PDC). Concurrent adherence was calculated as: PDC with >= 1 OHAs; average PDC; PDC of >= 80% for all OHAs. Results: Multivariable ordered logit model revealed that compared to others, risk-seeking patients had lower PDC with >= 1 OHAs (beta = -0.50, p <= .1). Specifically, risk-seeking patients were 11.2 percentage points less likely to have >= 80% of the follow-up period covered with >= 1 OHAs available (p <= .1). In addition, risk-seeking patients had lower average PDC (beta = -0.85, p <= .05). Specifically, these patients were 19.5 percentage points less likely to have an average PDC of >= 80% (p <= .05). Multivariable logistic model revealed that risk-seeking was associated with lower probability of having PDC >= 80% for all OHAs in the follow-up period (OR; 90% CI: 0.59; 0.35-0.97). Conclusions: Risk-seeking patients are less adherent to OHA medications. Identifying these patients may enable practitioners to proactively tailor strategies to improve their adherence and health outcomes.
