Background
The National Health Interview Survey has been one of the principal sources of information that enables public health sectors to monitor the health status of the population. The first National Health Interview Survey (NHIS) in Taiwan was conducted in 2001 with joint efforts form the National Health Research Institutes (NHRI) and the Taiwan HPA. Since then, the survey has been conducted every four years to collect policy relevant information which enables policy making and program evaluation.

Aim of the Survey

● To investigate people’s health status and health behavior
● To understand people’s medical and preventative care utilization
● To collect policy relevant information for decision making and program evaluation

Sampling and Survey Method

The most recent survey was conducted in 2013. The interviewees in this survey comprised a national and city/county representative sample of the whole population in Taiwan, including the residents of the aboriginal townships and the off-shore islands. Multistage stratified systematic sampling design was applied. The townships were stratified by the urbanization and location before sampling. Village/Lin in sampled townships and then individual in sampled village/Lin were selected step by step following the principle of probability proportional to size (PPS).

Content of the Survey 

Data was collected using face to face interview.  There were three sets of questionnaire designated for interviewees aged under 12, 12 to 64, and 65 or above respectively. The contents of the questionnaire are:
● Personal characteristics
● Health status
● Knowledge on disease prevention
● Medical and preventive care utilization
● Health behaviors
● Occupation and economic status
An additional module of self-administered questionnaire was applied in 2005 and 2009 with the involvement of National Bureau of Controlled Drugs (NBCD), now merged into the Food and Drug Agency, to investigate prevalence of illicit drug use.
