Objective:
We conducted a population-based study to assess whether work as a nurse during pregnancy increases the risk of low birth weight, preterm delivery, and small-for-gestational-age.
Methods:
The study population was selected from The Finnish Prenatal Environment and Health Study of 2568 newborns (response 94%) and included 128 (5.0%) newborns of nurses and 559 newborns of office workers (21.8%) as a reference group.
Results:
The risk of low birth weight (adjusted odds ratio = 1.02; 95% confidence interval = 0.32-3.22) and preterm delivery (0.81; 0.32-2.05) did not differ between newborns of nurses and office workers, but the risk of small-for-gestational-age was substantially higher among newborns of nurses (1.99; 1.10-3.59). This corresponds to a population attributable fraction of 2.5%.
Conclusions:
The results indicate that working as a nurse during pregnancy could reduce fetal growth.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
