Abstract

Osteoporosis is a skeletal disorder characterized by reduced bone mineral density leading to increased skeletal fragility and fracture risk. It occurs more frequently in postmenopausal women and is considered a public health problem. Studies have evaluated the relationship between diet and bone health but only a few use the approach of dietary pattern, and none of these was developed in Brazil. Considering this gap, the main objective of the present study is to evaluate the relationship between dietary patterns and bone mineral density in adult women. The study is part of a project developed at the Federal University of Sao Paulo, which was approved by the local Ethics Committee (CEP 0839/08). This study will be cross-sectional with estimated sample size of 170 women over 50 years. The bone mineral density (BMD) will be measured using dual-energy x-ray absorptiometry DXA using the Discovery A bone desnsitometer (Hologic) and the diagnostic criteria for osteoporosis will be that proposed by the World Health Organization (WHO). Food intake will be assessed by analysis of three food records processed in the software Nutrition Data System for Research (NDS-R, University of Minnesota) 2007 version. The dietary pattern will be performed by data reduction techniques using between-food group correlations from diet records into smaller sets of variables to define dietary patterns (factor analysis), thus associating with bone mineral density. The results will be analyzed as mean ± SD. The Kolmogorov-Smirnov test will be used to verify variables normality. P values d 0.05 will be considered significant.
