Water Damage >> Health Effects Of Hurricane Katrina

Health Effects of Exposure to Water-Damaged New Orleans Homes Six Months After Hurricanes Katrina and RitaWe found significant positive associations between exposure to water-damaged homes and URS score (P< .05), LRS score (P= .01), Health Effects Of Hurricane Katrina and overall symptom score (P< .01) in the multiple linear models (Figure 2 ). 

In the URS analysis, the least squares mean symptom score was 1.6 for participants who had not been inside a water-damaged home Health Effects Of Hurricane Katrina and 2.7 for participants in the highest exposure category (P< .01 for trend). 

However, we noted a relatively larger increase in mean symptom score between the first 2 exposure categories ("had not been inside" and "had been inside but had not participated in clean-up") than between other consecutive exposure categories. We also found the same patterns in the models of LRS score Health Effects Of Hurricane Katrina and overall respiratory symptom score. 

Adjusted mean symptom scores for upper, lower, Health Effects Of Hurricane Katrina and overall respiratory symptoms since Hurricanes Katrina and Rita among residents (N = 522), by extent of exposure to water-damaged homes: Orleans Parish, Louisiana, March 2006.

Those who reported still participating in clean-up activities had higher symptom scores in the models of URS score (least squares mean, Health Effects Of Hurricane Katrina LRS score (least squares mean, and overall respiratory symptom score (least squares mean of Health Effects Of Hurricane Katrina than did other participants (those no longer participating in clean-up activities and those who never participated in clean-up).

Models with participants stratified by asthma diagnosis showed similar patterns to those just described, Health Effects Of Hurricane Katrina generally reaching statistical significance for participants without asthma.Exacerbation of Respiratory Symptoms Among the 372 participants who had been inside a water-damaged home participating in clean-up.

Described exacerbation of URS when inside such a home. Those who Health Effects Of Hurricane Katrina reported still participating in clean-up were more likely to report exacerbation of mild URSs (odds ratio [OR] = 3.28; 95% confidence interval [CI] = 1.49, 7.25) and moderate or severe URSs (OR = 2.05; 95% CI = 1.07, 3.93) when inside than those who were no longer participating in clean-up. 

There was no difference between those who were still participating in clean-up Health Effects Of Hurricane Katrina and those who were not in terms of URSs that did not get worse when inside. The extent of exposure to water-damaged homes was not significantly associated with exacerbation of URSs when inside.

Participants who used only a mask during clean-up were more likely to Health Effects Of Hurricane Katrina report exacerbation of mild URSs when inside a water-damaged home (OR = 5.92; 95% CI = 1.34, 26.14) than were those who used no respiratory protection (Table 2 ). 

Those who used any type of respirator and those who specifically used an N-95 FF respirator less commonly reported both mild and moderate or severe URSs that got worse when inside than those who did not use a respirator; Health Effects Of Hurricane Katrina these differences did not reach statistical significance. There was no association between respirator use andURSs that did not get worse when inside.

Effect of Using Respiratory Protection During Clean-Up of Water-Damaged Homes on Upper Health Effects Of Hurricane Katrina and Lower Respiratory Symptoms Among Residents (N = 351): Orleans Parish, Louisiana, March 2006Of those who participated in clean-up, 77 (21%) described exacerbation of LRSs when inside. 

Those who reported still participating in clean-up were more likely to report exacerbation of mild LRSs (OR = 2.42; 95% CI = 1.04, 5.60) and Health Effects Of Hurricane Katrina moderate or severe LRSs (OR = 1.99; 95% CI = 0.95, 4.16) when inside than were those who were no longer participating in clean-up. 

There was no difference between those who were still participating in clean-up Health Effects Of Hurricane Katrina and those who were not in terms of LRSs that did not get worse when inside. The extent of exposure to water-damaged homes was not significantly associated with exacerbation of LRSs when inside.

Participants who used only a mask during clean-up were less likely to report moderate Health Effects Of Hurricane Katrina or severe LRSs that got worse when inside a water-damaged home than were those who used no respiratory protection, but this difference was not statistically significant (Table 2 ). 

Those who used any type of respirator were less likely to report exacerbation of mild LRSs (OR = 0.42; 95% CI = 0.18, 0.97) Health Effects Of Hurricane Katrina and moderate or severe LRSs (OR = 0.47; 95% CI = 0.22, 0.98) when inside than were those who did not use a respirator. 

Those who specifically used an N-95 FF respirator were less likely to report moderate Health Effects Of Hurricane Katrina or severe LRSs that got worse when inside (OR = 0.33; 95% CI = 0.13, 0.83) than were those who did not use a respirator. We saw a similar pattern for N-95 FF respirator use and exacerbation of mild LRSs when inside, but this difference did not reach statistical significance. 

There was no association between respirator use Health Effects Of Hurricane Katrina and LRSs that did not get worse when inside. DISCUSSION Participation in this survey of New Orleans residents 6 months after Hurricanes Katrina and Rita was high, reflecting widespread concern about exposure to water-damaged homes.

Respiratory symptoms were common: two thirds of respondents reported experiencing at least 1 URS and Health Effects Of Hurricane Katrina close to half reported experiencing at least 1 LRS since the hurricanes. 

Although we know of no other population-based surveys of respiratory symptoms following hurricanes or floods, these findings are consistent with previous investigations using hospital-based surveillance, Health Effects Of Hurricane Katrina which have generally found respiratory illnesses to be among the most common diagnoses recorded postdisaster, including following Hurricanes Katrina and Rita. 

We found a strong association between respiratory symptoms and exposure to water-damaged homes. Whether measured by individual-period prevalence or aggregated score (an approach used successfully in a population-based study of asthma17), Health Effects Of Hurricane Katrina symptoms increased with exposure. 

These results corroborate a growing body of scientific evidence of an Health Effects Of Hurricane Katrina association between exposure to indoor dampness or mold and respiratory health effects. 

Although tests of linearity were significant, the largest increases in mean symptom scores came between the first 2 exposure categories (category 0, those who had not been inside a water-damaged home, Health Effects Of Hurricane Katrina and category 1, those who had been inside but had not participated in clean-up).
