Nation-wide profile of women using hormonal contraception in Finland in 2017


 
 
 Up to 69% of European women use contraception. Nordic countries have traditionally high levels of contraception use, of welfare and social equality. However, the uneven population distribution across the Finnish territory makes the easiness of access to health care structures and trained professionals an important issue in relation to effective contraception use. Understanding the patterns of contraception prescription and their underlying determinants is crucial to guarantee the best contraceptive option for each woman.
 
 
 
 In Finland, users of hormonal contraception (HC) can be identified from register records only starting from 2017. This nationwide, register-based study includes all women with at least one HC prescription in 2017, and a reference cohort of non-users, matched by age and municipality. Through linkages to Finnish National Registers we retrieved sociodemographic data. We calculated national and regional rates and distributions, and compared distributions with t-test, Kruskal Wallis or Chi-squared test.
 
 
 
 The HC cohort included 294445 women aged 15-49 years (mean 28.9, SD 8.6), 25.8% of Finnish women of that age range. The majority of them were unmarried (71.8%) and employed (71.6%). Compared to non-users, HC users were more often unmarried, a cohabiting couple without common children, employed, had upper secondary or bachelor level education, and higher annual income (p < 0.001). Differences between HC users and non-users were non-homogenous across 70 Finnish regions.
 
 
 
 These preliminary results show different sociodemographic correlates of HC use across Finnish regions. Our findings will guide public health strategies aimed at guaranteeing the best contraceptive option for each woman across the whole country.
 
 
 
 Sociodemographic correlates of HC use differ across Finnish regions. These differences may reflect differences in access to health care services, in prescribers’ characteristics and in HC methods.
