| Abstract |
BACKGROUND: Very high plasma homocysteine levels are characteristic of
homocystinuria, a rare autosomal recessive disease accompanied by the
early onset of generalized osteoporosis. We therefore hypothesized that
mildly elevated homocysteine levels might be related to age-related
osteoporotic fractures. METHODS: We studied the association between
circulating homocysteine levels and the risk of incident osteoporotic
fracture in 2406 subjects, 55 years of age or older, who participated in
two separate prospective, population-based studies. In the Rotterdam
Study, there were two independent cohorts: 562 subjects in cohort 1, with
a mean follow-up period of 8.1 years; and 553 subjects in cohort 2, with a
mean follow-up period of 5.7 years. In the Longitudinal Aging Study
Amsterdam, there was a single cohort of 1291 subjects, with a mean
follow-up period of 2.7 years. Multivariate Cox proportional-hazards
regression models were used for analysis of the risk of fracture, with
adjustment for age, sex, body-mass index, and other characteristics that
may be associated with the risk of fracture or with increased homocysteine
levels. RESULTS: During 11,253 person-years of follow-up, osteoporotic
fractures occurred in 191 subjects. The overall multivariable-adjusted
relative risk of fracture was 1.4 (95 percent confidence interval, 1.2 to
1.6) for each increase of 1 SD in the natural-log-transformed homocysteine
level. The risk was similar in all three cohorts studied, and it was also
similar in men and women. A homocysteine level in the highest age-specific
quartile was associated with an increase by a factor of 1.9 in the risk of
fracture (95 percent confidence interval, 1.4 to 2.6). The associations
between homocysteine levels and the risk of fracture appeared to be
independent of bone mineral density and other potential risk factors for
fracture. CONCLUSIONS: An increased homocysteine level appears to be a
strong and independent risk factor for osteoporotic fractures in older men
and women. |
