title: National Health Interview Survey, 2006

description: &lt;p&gt;The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. Implementation of a redesigned NHIS, consisting of a basic module, a periodic module, and a topical module, began in 1997 (see NATIONAL HEALTH INTERVIEW SURVEY, 1997 [ICPSR 2954]). The 2006 NHIS contains the Household, Family, Person, Sample Adult, and Sample Child files from the basic module. Each record in Part 1, Household Level, contains data on type of living quarters, number of families in the household responding and not responding, and the month and year of the interview for each sampling unit. Part 2, Family Level, is made up of reconstructed variables from the person-level data of the basic module and includes information on sex, age, race, marital status, Hispanic origin, education, veteran status, family income, family size, major activities, health status, activity limits, and employment status, along with industry and occupation. As part of the basic module, Part 3, Personl Level, provides information on all family members with respect to health status, limitation of daily activities, cognitive impairment, and health conditions. Also included are data on years at current residence, region variables, height, weight, bed days, doctor visits, hospital stays, and health care access and utilization. A randomly-selected adult in each family was interviewed for Part 4, Sample Adult, regarding respiratory conditions, use of nasal spray, renal conditions, AIDS, joint symptoms, health status, limitation of daily activities, and behaviors such as smoking, alcohol consumption, and physical activity in addition to questions regarding stroke, diabetes, arthritis, and weight control. Part 5, Sample Child, provides information from an adult in the household on medical conditions of one child in the household, such as respiratory problems, seizures, allergies, and use of special equipment like hearing aids, braces, or wheelchairs. Also included are variables regarding child behavior, the use of mental health services, and Attention Deficit Hyperactivity Disorder (ADHD), as well as responses to the SDQ, the Strengths and Difficulties questionnaire on child mental health. The 2006 data contain the Child Mental Health Brief (CMB), Child Mental Health Services (CMS) and Child Influenza Immunization (CFI) sections. Part 6, Injury/Poison Episode, is an episode-based file that contains information about the external cause and nature of the injury or poisoning episode and what the person was doing at the time of the injury or poisoning episode, in addition to the date and place of occurrence. Part 7, Injury/Poison Episode Verbatim, contains edited narrative text descriptions of the injury or poisoning, provided by the respondent. Imputed income files for 2006 are now available through the NCHS Web site . (Source: downloaded from ICPSR 7/13/10)&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Please Note:&lt;/strong&gt; This dataset is part of the historical CISER Data Archive Collection and is also available at ICPSR -- &lt;a href="https://doi.org/10.3886/ICPSR20681.v3"&gt;https://doi.org/10.3886/ICPSR20681.v3&lt;/a&gt;. We highly recommend using the ICPSR version as they made this dataset available in multiple data formats.&lt;/p&gt;

description: collection_notes: The data collected in the NHIS are obtained through a complex sample design involving stratification, clustering, and multistage sampling. Because of this complex design and adjusted sampling weights, the direct application of standard statistical analysis methods for estimation and hypothesis testing to unweighted data may yield misleading results. If data are not weighted, severely biased estimates may result. For this reason it is necessary to use the weights that are included in the accompanying data file for analyses.
