Background:

The effect of circumcision on feeding behavior in the newborn period is unknown. We hypothesized that circumcision would not have a significant effect on newborn feeding.

Methods:

This prospective study analyzed the effect of circumcision on neonatal feeding behavior. Inclusion criteria were healthy male infants WHO were exclusively bottle-fed and underwent a circumcision before discharge from the newborn nursery. We collected data (N = 42) on gestational age, birth weight, Apgar scores, maternal age, gravid status, anesthesia used during delivery, analgesia used after circumcision, time of circumcision, and volume and frequency of feeding before and after circumcision. Data were analyzed by using paired t tests, multivariable regression analysis, and analysis of variance (with SPSS version 18). Significance was P < .05 (2-tailed α).

Results:

Descriptive statistics for the entire group (N = 42) are as follows: mean ± SD gestational age: 38.7 ± 1.2 weeks; mean birth weight: 3.3 ± 0.4 kg; maternal age: 26.7 ± 6.3 years; baseline feeding (mean of first 2 feedings before circumcision): 24.5 ± 9.9 mL; mean first feeding after circumcision: 21.7 ± 11.9 mL; and mean second feeding: 26.7 ± 13.5 mL. Forty-eight percent of patients increased their feeding volume after circumcision compared with baseline, and 52% of patients decreased their feeding volume, which persisted with the second feeding. There was no statistical difference between the baseline and first feeding (P = .11) or second feeding (P = .22).

Conclusions:

Our data suggest that circumcision does not alter feeding after circumcision. This information will be useful in counseling families regarding circumcision in the newborn period.
