Variations in the Number of Births by Day of the Week, and Morbidity and Mortality in Very-Low-Birth-Weight Infants

Abstract

The present results suggest that current care practices reduce the proportion of births during the weekends and tend to cluster some high-risk births during this period, increasing crude morbidity and mortality. However, after adjusting for confounding factors, the differences disappear, suggesting that overall care coverage in these centers is appropriate.
