    The effect of socioeconomic variables was evaluated with multiple logistic regression after stratification and adjustment for age, origin, centre, and selected reproductive and dietary factors.


    Compared to housewives, managers and professionals had a 1.7-fold increased risk, whereas the relative risk was 0.7 and 0.6 respectively in helpers and manual workers.

    The risk of breast cancer also increased with increasing social level of the husband's occupation and subject's number of years of schooling.

    Women who originated in central and southern Italy, and migrated to northern Italy after age 24, but not those who migrated at a younger age, had a relative risk of 0.6 and 0.7 respectively, compared to lifelong residents in northern Italy.


    Our findings show that correlates of sociocultural level and place of origin exert an influence on breast cancer risk which is not accounted for completely by known risk factors (i.e. (...)
