Adherence to preventive statin therapy according to socioeconomic position

Research output: Contribution to journalJournal articleResearchpeer-review

AIM: To explore whether long-term adherence to preventive statin therapy depends on socioeconomic position (SEP). METHODS: A cohort of individuals without established cardiovascular disease (CVD) or diabetes initiating preventive statin therapy during 2002-2005 was followed in the individual-level Danish registries for 4 years or until censoring events (death, emigration, CVD or diabetes). Only individuals aged 40-84 years for whom information was available on the SEP indicators, education and income were included (N = 76,038). Two different aspects of poor adherence were applied as outcome measures: (1) Proportion of days covered (PDC) with medication below 80 %, assuming a daily dose of one tablet (continuity); (2) Discontinuation defined as a gap between two consecutive prescriptions exceeding 365 days (persistence). Stratum-specific logistic regression analyses were applied to estimate the odds ratio (OR) for PDC
