Abstract


Introduction:

Bone discordance is new challenge in order to diagnosis of osteoporosis especially among postmenopausal women, there are many causes have been proposed for occurrence of this phenomenon.

Objective:

This study was conducted to evaluate the effect of major dietary pattern on bone discordance. 

Design:

Cross-sectional study

Settings:

The volunteer had completed demographic data. Dietary intake was assessed with a 147- item food frequency questionnaire (FFQ). Dietary patterns were created by factor analysis from 25 food groups. Dual-energy x-ray absorptiometry (DXA) was performed on the lumbar (L2-L4) and hip for cases.

Subjects:

We designed a cross-sectional survey of 258 postmenopausal women From June 2015 to February 2016.

Results:  

Three major dietary patterns were identified by using factor analysis based on baseline intake data: Unhealthy, Mediterranean and Western diet. After analysis we found 53.4% were concordance and 42.8% (4% were in the major discordance group) of participants were discordance. We found discordance group were younger, and obese participants were more talented to be in the major discordance group. We found inversely relationship between unhealthy dietary pattern and hip and lumbar Z score, while there was positive relationship between Mediterranean dietary pattern and hip BMD. No associations were found between dietary pattern and bone discordance.

Conclusions:

This study concluded that bone discordance was directly related to obesity in other words, and obese and younger women were at risk of bone discordance. Unhealthy and Mediterranean dietary pattern were negatively and positively related to bone density among postmenopausal women. This study showed, there was no association between any bone discordance situation and dietary pattern.
