National Health Interview Survey, 2013

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. The redesigned NHIS questionnaire introduced in 1997 (see NATIONAL HEALTH INTERVIEW SURVEY, 1997 [ICPSR 2954]) consists of a Core that remains largely unchanged from year to year, plus an assortment of Supplements sponsored by other agencies than NCHS, with the assortment varying from year to year. The 2013 NHIS Core components contain Household, Family, Person, Sample Adult, and Sample Child files. 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, Person Level, provides information on all family members with respect to health status, limitation of daily activities, cognitive impairment, and health conditions. Also included are variables related to doctor visits, hospital stays, and health care access and utilization. A randomly-selected adult in each family was interviewed for Part 4, Sample Adult Level, regarding respiratory conditions, renal conditions, AIDS, joint symptoms, health status, limitation of daily activities, and behaviors such as smoking, alcohol consumption, and physical activity. Part 5, Sample Child Level, 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. 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, Family Disability Level, seeks to identify the subpopulation that is at a greater risk than the general population of experiencing restrictions in social participation, for example, restrictions in employment, education, or civic life. Part 8, Adult Functioning and Disability Level, contains information about a respondent's functioning in various basic and complex activity domains: vision, hearing, mobility, communication, cognition, upper body, affect, pain, and fatigue. Part 9, Paradata Level, does not contain health related information, but rather data which are related to the interview process, including measures of time, contact-ability, and cooperation.

国家健康访谈调查（NHIS）旨在收集关于疾病数量及分布、其致残及慢性损害的影响，以及人们所接受的健康服务类型的信息。1997年推出的重新设计的NHIS问卷（参见《国家健康访谈调查，1997年》[ICPSR 2954]）包括一个基本模块，该模块自年度间基本保持不变，以及由非国家卫生统计中心（NCHS）资助的多种补充内容，这些补充内容每年都有所不同。2013年NHIS的基本模块包含家庭、家庭、个人、样本成人以及样本儿童文件。第一部分，家庭层级，每条记录包含关于居住类型、家庭中响应和不响应的家庭数量，以及每个抽样单元的访谈月份和年份的数据。第二部分，家庭层级，由基本模块的个人层级数据重构的变量组成，包括性别、年龄、种族、婚姻状况、西班牙裔血统、教育程度、退伍军人身份、家庭收入、家庭规模、主要活动、健康状况、活动限制和就业状况，以及行业和职业等信息。作为基本模块的一部分，第三部分，个人层级，提供了关于所有家庭成员健康状况、日常活动限制、认知障碍和健康状况的信息。还包括与医生就诊、住院和健康护理可及性和利用相关的变量。第四部分，样本成人层级，对每个家庭随机选取的成人进行访谈，了解呼吸系统疾病、肾脏疾病、艾滋病、关节症状、健康状况、日常活动限制以及吸烟、饮酒和体育活动等行为。第五部分，样本儿童层级，提供了来自家庭成人的信息，关于家庭中一名儿童的医疗状况，例如呼吸问题、癫痫、过敏以及使用助听器、矫正器或轮椅等特殊设备。第六部分，伤害/中毒事件，是一个基于事件文件，包含关于伤害或中毒事件的外部原因和性质，以及事件发生时个人所从事的活动，以及事件发生的日期和地点。第七部分，家庭残疾层级，旨在识别那些比普通人群更有可能经历社会参与限制的亚群体，例如就业、教育或公民生活的限制。第八部分，成人功能与残疾层级，包含有关受访者在不同基本和复杂活动领域（视力、听力、行动能力、沟通、认知、上肢、情感、疼痛和疲劳）中的功能信息。第九部分，附加数据层级，不包含与健康相关的信息，而是与访谈过程相关的数据，包括时间、接触性和合作度的度量。
