The population-attributable fraction worth of smoking was 14.0 p.c. Extra physique mass index accounted for 14.73 p.c of RA incidence, whereas low alcohol consumption accounted for 8.21 p.c of RA danger. General, 32.69 p.c of RA circumstances had been attributed to smoking, obese or weight problems, and low alcohol consumption.
