Associations between the COVID-19 pandemic and women's fertility intentions: a multi-country, cross-sectional (I-SHARE) study.

INTRODUCTION: The COVID-19 pandemic, together with the subsequent social distancing measures, could lead to shifts in family and fertility planning. This study aimed to explore the associations between the COVID-19 pandemic and changes in fertility intentions among an international sample of reproductive-aged women. METHODS: A multi-country, cross-sectional study based on data from 10 672 women aged 18-49 years who participated in the International Sexual Health And REproductive Health (I-SHARE) study, which organised an international online survey between July 2020 and February 2021. Factors associated with changes in fertility intentions were explored using multinomial probit regression models. Cluster-robust standard errors were used to calculate model parameters. RESULTS: Of 10 672 included reproductive-aged women, 14.4% reported changing their fertility intentions due to the pandemic, with 10.2% postponement and 4.2% acceleration. Women who had ever been isolated/quarantined were more likely to postpone their fertility intentions (adjusted odds ratio (AOR)=1.41; 95% CI 1.18 to 1.69) compared with those who had not; women who lived with a steady partner were more likely to want children sooner (AOR=1.57; 95% CI 1.10 to 2.23) compared with those who did not; and those who reported a higher frequency of getting angry, feeling frustrated, or worrying about their finances were more likely to postpone their fertility intentions. The main findings were robust in the sensitivity analyses. CONCLUSIONS: Most women who changed fertility intentions because of the pandemic have postponed intentions to expand their families. The pandemic-induced exposures were associated with these postponements.
