Introduction

Impact of Hurricanes Katrina and Rita on Substance Use and Mental Health: Detailed Tables is a collection of tables presenting estimates from adults aged 18 or older from the National Survey on Drug Use and Health (NSDUH) for the Gulf State Disaster Area affected by Hurricanes Katrina and Rita.¹ This web-only publication is designed to provide tables showing greater detail than those shown in the printed NSDUH Report on this topic.² These tables present information on the following topics:

• population;
  
• occupation;
  
• drug, alcohol, and tobacco use;
  
• drug and alcohol dependence and abuse and treatment;
  
• mental health problems and related treatment; and
  
• availability of illicit drugs.
  

Measures of these behaviors and characteristics are presented by a variety of demographic, geographic, and other variables. The estimates in the tables include rates of the behaviors, numbers of persons engaging in these behaviors, and other measures.

These tables are divided into two sections. The first set presents data on the prevalence of substance use and mental health problems, mental health treatment, and treatment needs before and after Hurricanes Katrina and Rita among adults aged 18 or older who lived in the Gulf State Disaster Area, and for comparison, in the rest of the United States. Estimates of substance use and mental health problems before Hurricanes Katrina and Rita were based on NSDUH data from July 2004 through June 2005. Estimates for the post-hurricane period were based on NSDUH data from January through December 2006. The second set of tables examines post-hurricane prevalence rates of substance use and mental health problems among Gulf State adults who were displaced from their homes as a result of the hurricanes compared with those in the disaster area who were not displaced. These tables utilize special questions added to NSDUH in 2006 in which respondents who had lived in a State bordering the Gulf of Mexico before the hurricanes were asked if they had left their home and stayed overnight in temporary housing (any place someone stays overnight or longer that is not thought of as his or her permanent home) as a result of either Hurricane Katrina or Rita.³

A description of the survey measurement issues and the sample design and estimation procedures used in the 2006 NSDUH can be found in technical appendices of the report titled Results from the 2006 National Survey on Drug Use and Health: National Findings.⁴ To reflect population changes in the Gulf State Disaster Area following the hurricanes, the analysis weights for the 2006 NSDUH were adjusted to the county- or parish-level population estimates derived from the 2006 U.S. census.⁵

Table Numbering

These Detailed Tables are numbered using a two-part numbering scheme (e.g., 15A). The first part of the table number (15A) is the number of the table, and the second part (15A) is a table-type indicator, an alphabetic letter appended to the table number. Each table number, as explained below, has multiple table types.

The tables are divided into two content areas. The content areas and the number of tables per content area are as follows:

• Section 1: Comparisons Before and After the Hurricanes - Tables 1 to 33 and
• Section 2: Effects of Displacement on Substance Use and Mental Health - Tables 34 to 51.

The table-type indicators are primarily defined as follows; however, some exceptions are noted in the subsequent bullets.

The majority of tables within these Detailed Tables contain five table types (A, B, C, D, and P) as defined above. The exceptions to this are Tables 35 and 37, which do not contain table type A. Tables 35A and 37A would be identical to Tables 34A and 36A, so the redundant tables were omitted.

Locating and Accessing a Table

These Detailed Tables are organized by table type into two categories:

• Prevalence Estimates - - Table Types A and B and;
  
• Standard Errors and P Values - - Table Types C, D, and P.
  

Both categories are organized based on the two sections as listed below. Clicking on the section of interest will take you to an index of tables for that section. Scroll through the list of table titles to find the table of interest, and click on the table title to go directly to that table. You need to return to the Table of Contents to access tables from other sections or categories.

The two sections are as follows:

• Section 1: Comparisons Before and After the Hurricanes and
  
• Section 2: Effects of Displacement on Substance Use and Mental Health.

End Notes

¹ The Gulf State Disaster Area includes the counties and parishes in Alabama, Florida, Louisiana, Mississippi, and Texas that were declared by the Federal Emergency Management Agency (FEMA) as eligible for Individual Assistance and/or Public Assistance following Hurricane Katrina and/or Hurricane Rita, with the exception of counties or parishes declared as eligible only for Public Assistance (Categories A or B).

³ Depending on their State of residence before the hurricanes, respondents were asked whether they had to leave their homes and stay in temporary housing because of the hurricanes. Respondents residing in Alabama, Florida, or Mississippi were asked about staying in temporary housing due to Hurricane Katrina; respondents residing in Texas were asked about staying in temporary housing due to Hurricane Rita; and respondents residing in Louisiana were asked about staying in temporary housing due to either hurricane. Standard NSDUH data collection procedures were used to identify displaced persons and temporary housing units. Specifically, if the person met the standard eligibility requirement of living in the selected dwelling unit at least half of the quarter, survey field staff were reminded to survey displaced persons wherever they currently were residing (e.g., at a friend's or relative's home). In addition, temporary housing units (e.g., hotel rooms, trailer homes on the grounds of selected dwellings, or groups of trailer homes that had not been present when the sample frame was initially built) that were observed by field staff were included as part of the sample if the unit fell in the geographic interval between a sampled dwelling unit and the next dwelling unit on the sample frame. If a large number of temporary units were encountered, these units were sampled at the same rate as the original sample. In addition to these standard procedures, some special procedures were employed. In the fourth quarter of 2005, NSDUH field staff were instructed to assign a pending status code to housing units that were vacant or damaged and to return midway through the quarter to see whether the dwelling unit had become reoccupied. In 2006, the first quarter sample was supplemented in the areas most affected by the hurricanes. For more information on the methods used to include displaced individuals, see the 2005 and the 2006 NSDUH sample design reports at http://oas.samhsa.gov/nsduh/methods.cfm.

⁵ For each of the five States that border the Gulf of Mexico, counties or parishes were aggregated to affected and unaffected areas. Within these areas, two strata were defined depending on population gain or loss from July 2005 to July 2006. The poststratification of the weights was done in such a way that for each stratum within an affected or unaffected area, the adjusted weights for age group (18 to 25, 26 to 34, 35 to 49, 50 to 64, 65 or older), race (white, black, others), gender, and Hispanic origin for within a State could be summed up to the corresponding population estimates from the U.S. census. The analysis weights for the pre-hurricane period also were adjusted to the county- or parish-level population estimates derived from 2004 and 2005 U.S. census. The poststratification for the pre-hurricane data was similar to the poststratification of the post-hurricane data, except that there were no strata defined within affected and unaffected areas within the five States.
