Résumé
BACKGROUND: Population ageing and longer duration of the working career could increase the prevalence of impairments and disabilities whereas there have been few data to help prevention and care. This study aimed at describing the prevalence of various types of impairments and assessing their social inequalities in the Lorraine population (north-eastern France). METHODS: The sample included 6.214 subjects aged 15 or more from 8.000 households randomly selected in the Lorraine population. A mailed questionnaire including socio-demographical characteristics, job, and various types of impairments was used. The data were analysed with the chi2 independence test, the adjusted odds ratio (OR) and the Mantel-Haenszel test. RESULTS: The prevalence of at least one impairment was 30% in both sexes. It varied from about 20% for subjects aged less than 40 years to about 60% for the subjects aged 70 years or more. It was higher in men than in women among the individuals aged more than 50 years (OR adjusted on age: 1.22, 95% CI: 1.04-1.44). The impairments were generally multiple for the subjects aged over 50. The prevalence of at least one impairment was higher for workmen (OR adjusted on age: 2.11, 95% CI: 1.68-2.66), farmers, craftsmen, traders and heads of firms (OR adjusted on age: 1.60, 95% CI: 1.17-2.18) and for employees (OR adjusted on age: 1.62, 95% CI: 1.29-2.03) in comparison with executives, intellectual professionals and teachers. For workmen a higher prevalence was observed for all types of impairments: intellectual and psychological functions, language, hearing, vision, visceral functions, and skeleton and posture. Farmers, craftsmen, traders, heads of firms and employees showed an excess for most types of impairments. Social inequalities were significant for various age groups during their period of occupational activity, but not after retirement. Unemployed people also had an excess of impairments. CONCLUSION: The prevalence of impairments strongly increased with advancing age. Marked inequalities were observed between various socio-occupational categories. Men were more affected than the women over 50 years of age. Impairments represent a health index which is useful for prevention to reduce their causes and consequences.
