Background Often diapers are not changed after infants pass urine.

Aim To define the association between the frequency of changing diapers and urinary tract infection (UTI) in infants.

Methods Urine samples were tested in 131 infants (aged from 2 months to 2.5 years) who had a temperature 38°C. The authors investigated the number of times diapers were changed daily. A total of 128 infants, excluding 3 cases, were divided into 2 groups: group A, without UTI (n = 96); group B, with UTI (n = 32). The number of times diapers were changed was compared between the groups.

Results In group A and group B, the number of times diapers were changed daily were 7.5 ± 1.4 and 4.7 ± 1.4, respectively. The number of times diapers were changed was significantly lower (P < .0001) in group B than in group A.

Conclusions Among infants wearing disposable diapers, there is an increased risk of UTI as the frequency of changing diapers decreases.

Key Words: urinary tract infection (UTI) • infant • disposable diapers • children
