Left-handedness has been associated with decreased longevity, although this finding is controversial and not universal.
The authors prospectively studied 39,691 women aged 55-69 years from the lowa Women's Health Study through 5 years of mortality follow-up.
No increase in mortality risk was found for left-handed women as compared with right-handed women (age-adjusted hazard ratio 1.10,95% confidence interval (Cl) 0.86-1.39) or for ambidextrous women (age-adjusted hazard ratio 1.05,95% Cl 0.73-1.49).
Adjustment for body mass index, body fat distribution, smoking, and education did not alter these findings.
Further analysis by cause-specific mortality (breast cancer, all other cancer, and circulatory disease) showed no relation to handedness.
