Objective      To determine the correlation of postmenopausal osteoporosis (PMOP) in Chong

qing with the level of intake nutrients and change of diet structure.       Methods      Semi-quantitative Food Frequency Questionnaire was used to make a survey on a total of 460 Chongqing females (including 152 PMOP and 308 non-PMOP) during June 2007 to June 2008 for their dietary structure. The levels of intake nutrients and diet structure between PMOP group and non-PMOP control group were compared. Non-conditional logistic model was used to estimate the correlation between risk factors and PMOP.       Results      In diet structure

there were negative correlations of higher average daily dietary intake of soy derived protein (

Vit A (

dark colored vegetables (

OR

95%

CI

=0.237-0.839) with the incidence of PMOP. Daily dietary intake levels of soy

fresh fruits

dark colored vegetables and milk in POMP group were lower than non-POMP group (

P

<

0.05)

and the daily dietary intake level of cooking oil in POMP group was higher than non-POMP group (

P

<

0.05).       Conclusion      Soy products

dark colored vegetables and milk can reduce the incidence of POMP. High level intake of animal derived protein and cooking oil can promote its incidence.
