Introduction This study aimed to examine Faroese infants' birthweight and gestational age in 2010–2019 and compare these findings with other Nordic countries. Risk factors for high birthweight among Faroese infants were also investigated in this study. Material and methods All singleton liveborn infants registered in the Faroese Birth Registry in 2010–2019 were included in the study (n = 6121). A comparison was made with data on birthweight and gestational age from Denmark, Iceland, Norway, and Sweden. Results The mean birthweight increased significantly from 3652 g (95% confidence interval [CI]: 3505–3699 g) in 2010 to 3745 g (95% CI: 3700–3790 g) in 2019, a mean increase in birthweight of 93 g (95% CI: 28–158 g) (p Conclusions Our results showed that the mean birthweight and the proportion of infants with high birthweight significantly increased during 2010–2019 in the Faroe Islands. The mean birthweight, the proportion of infants with high birthweight and the gestational age at birth for Faroese infants was higher than all other Nordic countries. The reasons for this require further investigation.

The birthweight increased 186 g (95% CI: 179-193 g) for each gestational week and 11 g (95% CI: 7-15 g) for each year. Changes in gestational age explained 31% of the change in ...
