Abstract

RODRIGUEZ-RAMIREZ, Sonia; MUNDO-ROSAS, Verónica; JIMENEZ-AGUILAR, Alejandra  and  SHAMAH-LEVY, Teresa. Methodology for the analysis of dietary data from the Mexican National Health and Nutrition Survey 2006. Salud pública Méx [online]. 2009, vol.51, suppl.4, pp.S523-S529. ISSN 0036-3634.  http://dx.doi.org/10.1590/S0036-36342009001000007.

OBJECTIVE: To describe the methodology for the analysis of dietary data from the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) carried out in Mexico. MATERIAL AND METHODS: Dietary data from the population who participated in the ENSANUT 2006 were collected through a 7-day food-frequency questionnaire. Energy and nutrient intake of each food consumed and adequacy percentage by day were also estimated. Intakes and adequacy percentages > 5 SDs from the energy and nutrient general distribution and observations with energy adequacy percentages < 25% were excluded from the analysis. RESULTS: Valid dietary data were obtained from 3552 children aged 1 to 4 years, 8716 children aged 5 to 11 years, 8442 adolescents, 15951 adults, and 3357 older adults. CONCLUSIONS: It is important to detail the methodology for the analysis of dietary data to standardize data cleaning criteria and to be able to compare the results of different studies.
