National Population Health Survey, 1994-1995 [Canada]: Supplements

The National Population Health Survey (NPHS) is designed to collect information related to the health of the Canadian population. The first cycle of data collection began in 1994, and will continue every second year thereafter. The survey will collect not only cross-sectional information, but also data from a panel of individuals at two-year intervals.The target population of the NPHS includes household residents in all provinces, with the principal exclusion of populations on Indian Reserves, Canadian Forces Bases and some remote areas in Quebec and Ontario. Separate surveys were conducted to cover the Yukon, the Northwest Territories and the Institutions (long term residents of hospitals and residential care facilities) and will be presented at a later stage. The NPHS data are stored in four different data sets. Some information was collected from all household members. This information is stored in the General file. From each household, one person, aged 12 years and over, was selected to answer a more in-depth questionnaire related to health. These data are stored on the Health file. Each record on the General file corresponds to a household member. The General file carries the socio-demographic variables as well as health utilization variables. There are 58,439 records and 129 variables in the General file. The Health file contains 17,626 records and 439 variables. The Supplemental file is a subset of the health sample. Certain individuals in the Health sample were asked to answer supplemental questions. This file contains 13,400 records and 1023 variables. A special component of the program is a survey designed for people living in health care institutions, including hospitals, nursing homes, and residential facilities for persons with disabilities. This Institutional file contains data collected in 1995 from 2287 long-term residents of health care institutions in the provinces. Data between the files can be linked using the variable recno. Note: This data is also linked to the National Longitudinal Survey of Children

全国人口健康调查（National Population Health Survey, NPHS）旨在采集与加拿大人口健康相关的各类信息。首次数据采集周期于1994年启动，此后每两年开展一轮调查。本调查不仅收集横断面研究数据，还以两年为间隔对固定追踪队列开展追踪调研。

NPHS的目标人群为加拿大所有省份的家庭常住居民，主要排除印度保留地、加拿大军事基地，以及魁北克省与安大略省部分偏远地区的人口。另有专项调查覆盖育空地区、西北地区及医疗机构（含医院长期住院患者、养老机构长期住客），相关数据将在后续阶段对外公布。

NPHS的数据存储于四个独立数据集：
1. 通用文件（General file）：面向所有家庭成员采集的信息存储于此，每条记录对应一名家庭成员，包含社会人口统计学变量与健康服务利用变量，该文件共包含58439条记录与129个变量。
2. 健康文件（Health file）：从每个家庭中选取1名12岁及以上成员，完成深度健康相关问卷调研，此类数据存储于此，共包含17626条记录与439个变量。
3. 补充文件（Supplemental file）：为健康样本的子集，健康样本中的部分受访者需作答补充问卷，该文件包含13400条记录与1023个变量。
4. 机构文件（Institutional file）：为本项目的特殊组成部分，针对医疗保健机构住客开展专项调查，涵盖医院、养老院及残疾人康复机构。该文件收录了1995年针对加拿大各省份2287名医疗保健机构长期住客的采集数据。

各数据集可通过变量recno实现数据关联。注：本数据集还与全国儿童纵向调查（National Longitudinal Survey of Children）相关联。
