Introduction. Osteoporosis is a complex, multi-factorial
bone disease leading to increased risk of fracture. Calcium as
a nutrient is associated with the formation and metabolism of
bone. The inadequate calcium intake leads to decreased bone
mineralization and consequently an increased risk of
Materials and methods. The study group was
constituted by 104 postmenopausal women. Bone mineral
density (BMD) at the participants’ lumbar spin and hip was
measured by dual-energy X-ray absorptiometry (DXA). The
daily calcium intake (DCI) was assessed using a validated
quantitative food frequency questionnaire (FFQ). Each
participant also completed a core questionnaire that included
general demographic data as well as questions about personal
and family history of fractures, menopause onset, lifestyle
behaviors, and corticosteroids use.
Results and discussion. The mean daily calcium intake
among our study participants was 854.3±260.4 mg which is
below the calcium recommended nutrient intake (RNI) for
postmenopausal women. This study’s findings confirmed
that the reduction of the bone mineral density (BMD),
reported using T-scores, depends on age and choice of
measurement site. Our results also showed that higher body
mass and body mass index (BMI) in participants are
associated with higher BMD. The reduced bone density
among postmenopausal women was related with the
existence of previous personal fractures and the family
history of fractures in diagnosed persons. The insight into
exogenous risk factors of osteoporosis in this study showed
that the most of the participants consume caffeine every day
and have insufficient physical activity and sun exposure.
Conclusions. Education on the importance of calcium in
the diet and knowledge on the lifestyle factors that affect
bone loss are needed toward decreasing risk for osteoporosis
and related fractures in postmenopausal women.
