[Social differences and indicators of perceived health, chronic diseases, disability and life style in the 1994. ISTAT national health interview survey].

In this paper social differences in health, analysed by different dimensions (perceived health, chronic diseases, functional deficits and disability) and social differences in lifestyle, in particular smoking habit and use of health services for the prevention of some female tumours, are described. The study is based on the data collected in the National Interview Survey on Health Status and Use of Health Care Services, conducted by ISTAT in the 1994. The analysis has been performed separately for males and females, computing Prevalence Rate Ratios (PRR) standardized by age. Educational level and social class, based on Schizzerotto's classification, have been used as determinants of differences in health and lifestyle. Unfavourable perception of health status and most of chronic diseases, referred as diagnosed by a doctor, show an increasing prevalence with decreasing educational level. Less striking differences are observed in the occurrence of injuries and in the restriction of daily life activities caused by diseases. A lower educational level corresponds to a regular increase in the proportion of disabled subjects. Females show higher differences than males in overweight and underweight prevalences in favour of more educated. Smoking habit shows an inverse correlation with education in males and a direct correlation in females, while attempts to quit smoking are more common among more educated individuals. Among women, the tendency to use screening tests for the prevention of some tumours is directly proportional to the educational level. Similar findings were obtained using the social class, with small bourgeoisie and working class showing similar excess risks, compared to bourgeoisie. This study found significant social inequalities in health status and in lifestyle in Italian population in 1994. The discussion argues that in absence of preventive interventions on disadvantaged groups of the population an increase of social differences in health is predictable.
