Childhood urinary symptoms predict adult overactive bladder symptoms

A relationship between childhood urinary symptoms and adult lower urinary tract symptoms in women is often clinically suspected. In this analysis we investigated the relationship between childhood and adult urinary symptoms in middle-aged women.

A population based cohort of 2,109 women 40 to 69 years old who were members of a large health maintenance organization was randomly selected from age and race strata. Through self-reported questionnaires, women recalled a childhood history of and current urinary lower urinary tract symptoms, including frequent daytime urination, nocturia, urinary incontinence, nocturnal enuresis and UTIs. Current incontinence was also classified as urge or stress incontinence. Multivariate analysis was used to evaluate the association between childhood and current lower urinary tract symptoms controlling for age, race, hysterectomy status, parity, oral estrogen use, body mass index and diabetes.

Women who reported childhood daytime frequency were more likely to report adult urgency (OR 1.9, 95% CI 1.3-2.6, p < 0.001). Frequent nocturia in childhood was strongly associated with adult nocturia (OR 2.3, 95% CI 1.5-3.5, p < 0.001). Childhood daytime incontinence was associated with adult urge incontinence (OR 2.6, 95% CI 1.1-5.9, p < 0.05), as was childhood nocturnal enuresis (OR 2.7, CI 1.3-5.5, p < 0.01). A history of more than 1 childhood UTI was associated with adult UTIs (OR 2.6, 95% CI 1.5-4.5, p < 0.001).

Childhood urinary symptoms and UTIs were significantly associated with adult overactive bladder symptoms. There is a need to investigate the significance of childhood symptoms as predictors of eventual adult disorders to determine whether treatment of childhood symptoms will alter the prevalence of eventual adult disorders, and if such a history should alter clinical care of the older adult with OAB symptoms.
