The most important variables influencing prevalence of urinary tract infection (UTI) are age and sex ( ). In neonates, the rate for premature infants (2.9%) and very-low-birthweight infants (4 to 25%) exceeds that for full-term infants (0.7%). Male preponderance persists for the first 3 months of life, after which the prevalence rate among females exceeds that in males. The prevalence rate reported in girls 1 to 5 years of age is 1 to 3%, whereas few infections occur in boys of those ages. This is the age range in which children are most likely to experience a first symptomatic infection. Symptomatic infections occur 10 to 20 times more commonly in preschool-aged girls than in preschool-aged boys.
