Dietary iron intakes are useful in epidemiological studies and in conducting screening for at-risk groups. To date, there is no validated culturally sensitive semi-quantitative food frequency questionnaire (SFFQ) available for the estimation of dietary iron intake for Filipinos. This study aimed to determine the criterion and relative validity of a developed semi-quantitative food frequency questionnaire (SFFQ) for the estimation of iron intake among Filipino WRA. The study employed an exploratory mixed method design of grounded theory for the development of the SFFQ and cross-sectional, analytic design for the validity study to address the study objectives. Development phase involved creating food lists using FCT, data from the NNS and FGD while validation phase was conducted among 60 WRA, and data on dietary intake were acquired using SFFQ and 3-day nonconsecutive food record. A subsample of 36 study participants had their hemoglobin levels checked. Results showed that although the SFFQ had valid agreement for relative validity as assessed by the Bland-Altman method, the difference between the methods is significantly different (3.95±0.59 mg, p-value=0.000). For criterion validity, there is no significant correlation (r=0.0789, p-value=0.6472) between the SFFQ and biomarker. Findings of the study showed that the development process employed may not be sufficient and appropriate to produce a valid SFFQ for the estimation of iron intake. Food frequency questionnaires.
