Adverse respiratory symptoms and environmental exposures among children and adolescents following Hurricane Katrina.

OBJECTIVES: Children and adolescents are especially vulnerable to environmental exposures and their respiratory effects. Following Hurricane Katrina in 2005, residents experienced multiple adverse environmental exposures. We characterized the association between upper respiratory symptoms (URS) and lower respiratory symptoms (LRS) and environmental exposures among children and adolescents affected by Hurricane Katrina. METHODS: We conducted a cross-sectional study following the return of the population to New Orleans after Hurricane Katrina (October 2005 and February 2006) among a convenience sample of children and adolescents attending New Orleans health facilities. We used uni-, bi-, and multivariable analyses to describe participants, exposures, and associations with URS/LRS. RESULTS: Of 1,243 participants, 47% were Caucasian, 50% were male, and 72% were younger than 11 years of age. Multiple environmental exposures were identified during and after the storm and at current residences: roof/glass/storm damage (50%), outside mold (22%), dust (18%), and flood damage (15%). Self-reported URS and LRS (76% and 36%, respectively) were higher after the hurricane than before the hurricane (22% and 9%, respectively, p<0.0001). Roof/glass/storm damage at home was associated with URS (adjusted odds ratio [AOR] = 1.59, 95% confidence interval [CI] = 1.15, 2.21) and LRS (AOR=1.35, 95% CI 1.01, 1.80), while mold growth at home was associated with LRS (AOR=1.47, 95% CI 1.02, 2.12). CONCLUSIONS: Children and adolescents affected by Hurricane Katrina experienced environmental exposures associated with increased prevalence of reported URS and LRS. Additional research is needed to investigate the long-term health impacts of Hurricane Katrina.

Adverse health outcomes after Hurricane Katrina among children and adolescents with chronic conditions.

Children with chronic conditions may be at risk of increased disruptions in health care following natural disasters such as Hurricane Katrina. The objective of this cross-sectional study was to evaluate differences between children and adolescents with and without chronic conditions immediately following Katrina. Of 531 participants, there were 79.8% younger than 13 years old, 50.5% male, 42.8% African American. Participants with pre-existing conditions (39.4% of the total sample) were more likely than those without to be at the clinic for a non-chronic health condition rather than another problem (43.5 vs. 16.2%), to take asthma medication (37.4 vs. 3.9%), to have asthma worsen (16.3 vs. 1.9%), to miss a visit (49.2 vs. 39.8%), to run out of medications (33.9 vs. 7.9%), to live with flood damage (19.7 vs. 11.3%) or mold (23.6 vs. 15.8%), and to experience disruption in care (58.4 vs. 38.3%) or negative psychological consequences (ranging from 2.5% to 12.9%). While the medical differences are unsurprising, given the groups being compared, the other differences between the groups merit attention from policymakers and health care providers. Children and adolescents with chronic conditions are at increased risk of adverse outcomes following a natural disaster. Providers may be able to reduce negative effects on this population by developing condition-specific preparedness care mechanisms.
