Background/Objectives:
The aim of this study was to investigate the association between
dietary patterns and bone mineral density (BMD) in postmenopausal women with
osteoporosis.
Subjects/Methods:
This cross-sectional study included 156 postmenopausal and
osteoporotic Brazilian women aged over 45 years. BMD of lumbar spine, total
femur (TF), femoral neck and of total body (TB), as well as body composition
(fat and lean mass), was assessed by dual-energy X-ray absorptiometry. Body
mass index and lifestyle information were also obtained. Dietary intake was
assessed by using a 3-day food diary. Dietary patterns were obtained by
principal component factor analysis. Adjusted multiple linear regression analysis
was applied in order to evaluate the predictive effect of dietary patterns on
BMD. Significance was set at P less than 0.05.
Results:
Results:
Five patterns were retained: ‘healthy’, ‘red meat and refined
cereals’, ‘low-fat dairy’, ‘sweet foods, coffee and tea’ and ‘Western’. The
‘sweet foods, coffee and tea’ pattern was inversely associated with TF BMD (β=−0.178; 95% CI: −0.039 to −0.000) and
with TB BMD (β=−0.320; 95% CI:
−0.059 to −0.017) even after adjusting for energy and calcium intake, lean
mass, age and postmenopausal time.
Conclusions:
A concomitant excessive consumption of sweet foods and
caffeinated beverages appears to exert a negative effect on BMD even when the
skeleton already presents some demineralization. Food and beverage intake is a
modifiable factor that should not be neglected in the treatment of individuals
with osteoporosis.
