Hurricane Katrina victims who lost their homes in the tragedy are five times more likely to suffer from psychological distress than their counterparts who did not lose homes, a study led by an American researcher of Indian origin has found.
Narayan Sastry of the University of Michigan and Mark VanLandingham of Tulane University examined the mental health status of pre-Katrina residents of New Orleans in the fall of 2006, one year after the hurricane hit the city.
The researchers analysed disparities in mental health by race, education and income.
Conducting a pilot survey, they drew a stratified, area-based probability sample of pre-Katrina dwellings in the city, which formed the basis for the study.
The study, designed by a non-profit research organization called RAND Corporation, is one of the first to provide data representative of the pre-hurricane population.
Of the 144 persons who participated in the pilot study, many were those who moved away from the area after the disaster and had not returned a year later.
Over 50 per cent of the participants were black, nearly two-thirds had a high school diploma or less education, and nearly 60 per cent were unmarried. Nearly three-fourths were employed in the month before the hurricane hit.
Sastry revealed that about 60 per cent of study participants had no psychological distress at the time of the interview, about 20 per cent had mild-to-moderate mental illness, and another 20 per cent had serious mental illness.
