[Indirect morbidity indicators and social differences in the ISTAT quarterly workforce survey].

Information on the health condition job related of the population are often collected in specific studies, usually limited over time and concerned with a small part of the general population. Looking at official statistics, sources such as national health surveys (in Europe and in North America) are rich on health data, but often offer little information on job-conditions, and job history. On the other hand, one also can find official sources, mainly concerned with labour and job related topics, in which information related to the health status of the people interviewed are routinely collected. These are the Labour Force Surveys, carried out in the most of developed countries. In the Italian Labour Force Survey (RTFL) the Italian Statistical Institute (ISTAT) quarterly collects information on health-related sick absence, part-time job and unemployment. Data from RTFL of two Italian regions (Lombardy: 1985, '86, '89 and Veneto: 1985, '86) show differentials by age and job-position that are consistent with expectation, encouraging an extensive use of this source for surveillance purposes at the national and regional level.
