Previously, it has been shown that factors like ethnicity and proficiency of state's official language not only influence self-management abilities and medication adherence but may also indicate the level of trust in physicians, medication, and healthcare system. This research aims to examine the potential impact of ethnicity on medication adherence based on the example of a post-Soviet country. The research was carried out as a quantitative survey among 303 hypertension and type 2 diabetes patients in Estonia, involving participants from ethnic majority and minority. Research was conducted in community pharmacies and data analysed statistically with SPSS. The findings were opposite to previous research. Although members of the ethnic minority used less illness-related sources, these sources relied more on evidence-based medicine compared to the ethnic majority. Because of this, medication adherence was also slightly higher for the ethnic minority compared to the majority. Therefore, these findings indicate trust in medical authorities, their decisions, and recommendations. There was a statistically significant relationship between general and illness-related information-seeking activity; however, medication adherence was not related to information-seeking activity. The research outlines that in addition to ethnolinguistic aspect, also potential cultural influence might determine the trust in medicine and medication adherence.
