RESUMEN
The COVID-19 pandemic has burdened the healthcare system and influenced individuals' health-related choices. The aim of the study was to estimate the prevalence and to identify the correlates of the use of more and less effective contraceptive methods among Poles in the initial period of the COVID-19 pandemic. The cross-sectional online study was conducted among the representative sample of 642 female respondents aged 18-49. Three groups of contraception choices (only effective methods-42.2%, mixed effective and ineffective methods-26.8%, none-31.0%) were distinguished and 11 potential determinants were considered. One in ten women declared having difficulty in accessing contraception during the first months of the pandemic. A multinomial logistic regression model explained 48.7% of the variation in contraceptive method choice. Both effective and ineffective methods were more often declared by young women, and less often in case of lower education, planning children or subjective no need for contraception. In addition, factors that reduced the chance of effective contraception were poor financial situation, already having children and a relatively higher degree of religiosity. The study confirmed that a significant share of Polish women do not opt for effective methods of contraception. Their choices had strong demographic, social and cultural determinants.
