To examine the validity of a semi-quantitative food frequency questionnaire (SFFQ) to identify dietary patterns in an adult Mexican population. Materials and methods. A 140-item SFFQ and two 24-hour dietary recalls (24DRs) were administered. Foods were categorized into 29 food groups used to derive dietary patterns via factor analy- sis. Pearson and intraclass correlations coefficients between dietary pattern scores identified from the SFFQ and 24DRs were assessed. Results. Pattern 1 was high in snacks, fast food, soft drinks, processed meats and refined grains; pattern 2 was high in fresh vegetables, fresh fruits, and dairy products; and pattern 3 was high in legumes, eggs, sweetened foods and sugars. Pearson correlation coefficients between the SFFQ and the 24DRs for these patterns were 0.66 ( P <0.001), 0.41 ( P <0.001) and 0.29 ( P =0.193) respectively. Conclusions. Our data indicate reasonable validity of the SFFQ, using fac- tor analysis, to derive major dietary patterns in comparison with two 24DR. 2016 artículo científico 0036-3634 https://www.redalyc.org/articulo.oa?id=10649652016 en http://www.redalyc.org/revista.oa?id=106 Salud Pública de México application/pdf Instituto Nacional de Salud Pública Salud Pública de México (México) Num.6 Vol.58 |
