Diet, lifestyle and bone mineral density in elderly Japanese women

Diet, lifestyle and bone mineral density in elderly Japanese women

Alcohol and green tea drinking, and being physically active were associated
with greater bone mineral density (BMD) in Japanese women. Smoking and
cheese consumption were associated with lower BMD.

Comment: Only low to moderate consumption of alcohol is beneficial to bone.
Heavy drinking and binge drinking are harmful to bones.

BACKGROUND: Several studies have already demonstrated that lifestyle
characteristics, such as physical activity, smoking, and alcohol intake, are
associated with bone mineral density (BMD). Coffee intake was shown to be
negatively associated with BMD, whereas tea drinking was reported to be
associated with increased BMD. A review of the literature, however, revealed
that few studies have described the association between BMD and lifestyle,
including characteristic Japanese foods such as fish, natto, and Japanese
green tea. The aim of this study was to identify lifestyle factors
associated with BMD. METHODS: A total of 632 women age >/=60 years were
enrolled in this study. Subjects were interviewed about their lifestyle by
means of a questionnaire regarding the consumption pattern of dietary items.
BMD was measured at the lumbar spine by dual energy X-ray absorptiometry.
RESULTS: The BMD was higher in subjects with the habits of alcohol drinking,
green tea drinking, and physical activity and lower in those with the habits
of smoking and cheese consumption. Multiple regression analysis showed that
factors associated with BMD were smoking, alcohol consumption, green tea
drinking, and physical activity after adjusting for age and body mass index
(BMI). CONCLUSIONS: In this cross-sectional study at an osteoporosis
outpatient clinic, patients with the habits of alcohol drinking, green tea
drinking, and physical activity had significantly higher BMD, and those who
smoked had significantly lower BMD than patients without each habit after
adjusting for age, BMI, and other variables regarding lifestyle. PMID:

Bone density in relation to alcohol intake among men and women in the United
States.

Studies of postmenopausal women have shown a positive association between
BMD and alcohol intake. We found that BMD was higher in men, and possibly
postmenopausal women, who drank alcohol compared with those who abstained.
Drinking alcohol, but not binge drinking, may benefit bone health of men and
postmenopausal women. INTRODUCTION: Osteoporotic fractures account for over
2.5 million physician visits annually for persons ages >or=45 years in the
United States. Studies of postmenopausal women show a positive association
between bone mineral density (BMD) and alcohol intake, but for men and
premenopausal women, the bone-alcohol relationship remains unclear. We
examined the association between total hip (TH) and femoral neck (FN) BMD
and alcohol intake of men and pre- and postmenopausal women. METHODS: We
conducted multiple regression analyses using data from 13,512 persons ages
>or  years from the Third National Health and Nutrition Examination
Survey, 1988-1994. Alcohol intake and binge drinking were measured by
questionnaire and hip BMD by dual energy X-ray absorptiometry (DXA).
RESULTS: Accounting for covariates, TH BMD was higher in men (n = 6,868) who
had 5-29 (+2.1%, p < 0.01) and >29 drinking occasions/month (+1.7%, p <
0.05) than men who abstained. BMD of premenopausal women (n = 4,136) who
drank alcohol did not differ from those who abstained. FN BMD was 3.8%
higher in postmenopausal women (n = 2,043) who had >29 drinking
occasions/month than those who abstained (p = 0.06). Binge drinking was not
associated with BMD of men or women. CONCLUSIONS: Drinking alcohol, but not
binge drinking, appears to be beneficial to bone health of men and possibly
postmenopausal women. PMID: 17091218
