Resumen

RAMIREZ-SILVA, Ivonne et al. Methodology for estimating dietary data from the semi-quantitative food frequency questionnaire of the Mexican National Health and Nutrition Survey 2012. Salud pública Méx [online]. 2016, vol.58, n.6, pp.629-638. ISSN 0036-3634.  http://dx.doi.org/10.21149/spm.v58i6.7974.

Objective:

To describe the methodology used to clean up and estimate dietary intake (DI) data from the Semi-Quantitative Food Frequency Questionnaire (SFFQ) of the Mexican National Health and Nutrition Survey 2012.

Materials and methods:

DI was collected through a shortterm SFFQ regarding 140 foods (from October 2011 to May 2012). Energy and nutrient intake was calculated according to a nutrient database constructed specifically for the SFFQ.

Results:

A total of 133 nutrients including energy and fiber were generated from SFFQ data. Between 4.8 and 9.6% of the survey sample was excluded as a result of the cleaning process.Valid DI data were obtained regarding energy and nutrients consumed by 1 212 pre-school children, 1 323 school children, 1 961 adolescents, 2 027 adults and 526 older adults.

Conclusions:

We documented the methodology used to clean up and estimate DI from the SFFQ used in national dietary assessments in Mexico.
