ATLANTA, GA USA (PRESS RELEASE) - May 20, 2012 -
Exposure to environmental tobacco smoke can worsen urinary symptoms, including incontinence
Children exposed to environmental tobacco smoke (secondhand smoke), especially those 4–10 years of age, are at increased risk for irritative storage symptoms - urinary urgency, increased urinary frequency and incontinence - according to a new study at the 107th Annual Scientific Meeting of the American Urological Association (AUA). The study was presented to reporters during a special press conference at the Georgia World Congress Center, Atlanta, GA on Sunday, May 20 at 10:00 a.m.
Cigarette smoke contains known bladder irritants and is associated with the development of bladder cancer in adults. European studies have shown an elevated risk of bladder cancer among adults exposed to secondhand smoke during childhood; however, there is no current literature to address the urologic effects of secondhand smoke in children. Dr. Kelly Johnson and researchers from Robert Wood Johnson University Hospital and Rutgers University, New Brunswick, N.J. analyzed survey responses from 45 children ages 4–17. All children presented with storage symptoms prior to enrollment in the study. Parents of children 4–10 years of age completed the survey on the child’s behalf, while children 11-17 years of age self-reported. Storage symptom severity was quantified by clinical exam and classified as very mild, mild, moderate or severe.
Results suggest that exposure to secondhand smoke is associated with worsening of storage symptoms in children. Further, children with greater exposure to secondhand smoke had higher symptom severity scores compared to those who were not exposed. Specifically:
- Twenty-four children received moderate or severe storage symptom scores, while 21 children received a score of very mild or mild
- Of those who received a score of moderate or severe, 23 percent had mothers who smoked and 50 percent had exposure to secondhand smoke in an automobile on a regular basis. In contrast, of those who received a score of very mild or mild, none had mothers who smoked, nor were they exposed to secondhand smoke in an automobile
- For children 4–10 years of age, the relationship between increasing severity and secondhand smoke exposure was particularly pronounced [t-test (p=0.014); ANOVA (p = 0.008)] “Secondhand smoke is a leading cause of preventable death in the United States,” said Anthony Atala, MD, a pediatric urologist at Wake Forest Baptist Medical Center and a spokesperson for the AUA. “Beyond conditions such as lung cancer, heart disease and asthma, we now know that smoking has a negative impact on urinary symptoms, particularly in young children. Data presented today should be added to the indisputable evidence that parents shouldn’t smoke around their children.”
