Association of pharmacological treatments for hypertension, diabetes, and dyslipidemia with health checkup participation and identification of disease control factors among older adults in Tokyo, Japan

Highlights • We examined links between medical claims and health check-up data for older adults. • Patients receiving pharmacotherapies were more likely to participate in health checkups. • Patients with intensive disease control were more likely to be aged ≥ 90 years. • Linking these databases can improve evaluations of diseases control in older adults.
The Japanese government encourages older adults to participate in annual health checkups designed to detect lifestyle diseases such as hypertension, diabetes, and dyslipidemia. However, individuals who are already being treated for these diseases are unlikely to benefit from health checkup participation. This retrospective cohort study of older adults evaluated the associations of pharmacological treatments for these diseases with health checkup participation and identified the disease control factors among patients receiving treatments. Using medical claims data and health checkup data between September 2013 and August 2014 from 820,215 older adults aged ≥ 75 years residing in Tokyo, Japan, we examined the associations between pharmacological treatments and health checkup participation using binary logistic regression analysis. Next, patients receiving pharmacological treatments were categorized into intensive, moderate, or limited disease control based on their blood pressure, hemoglobin A1c levels, and lipid levels; multinomial logistic regression analyses were used to identify the disease control factors. The results showed that patients receiving pharmacological treatments were more likely (odds ratio: 1.374; P
