Anthropometric data for the different age and gender groups. Medicine refers to number of drugs used daily. Smoking is divided into never (N) and current (C) or prior (P) and given in percentages. Physical activity at work and during leisure time is reported in medians from 1 (least active) to 4 (most active) and variance as interquartile range
^amedian (interquartile range)
^bAn insignificant number of participants were working (i.e. most participants where fully retired)
