Objective: To analyze the relation between selected dietary indicators and
the risk of uterine myomas.
Methods: We used data from a case-control study on risk factors for uterine
myomas conducted in Italy between 1986 and 1997. Cases included 843 women
with uterine myomas whose clinical diagnoses dated back no more than 2 year
s. Controls were 1557 women younger than age 55 who had not had hysterectom
ies and were admitted for acute nongynecologic, nonhormonal, nonneoplastic
conditions.
Results: Women with uterine myomas reported more frequent consumption of be
ef, other red meat, and ham and less frequent consumption of green vegetabl
es, fruit, and fish. The multivariate odds ratios in the upper tertile were
1.7 for beef and other red meat (95% confidence interval [CI] 1.4, 2.2), 1
.3 for ham (95% CI 1.0, 1.6), 0.5 for green vegetables (95% CI 0.4, 0.6), a
nd 0.8 for fruit consumption (95% CI 0.6, 1.0).
Conclusion: Myoma is associated with beef and ham consumption, whereas high
intake of green vegetables seems to have a protective effect. (C) 1999 by
