Women's Health Food Frequency Questionnaire
Study Details
Study Description
Brief Summary
The aim of this study is to develop a tool that can measure the iron, folate, and vitamin B12 content of a diet through a literature review, database search, and a pilot study using a food consumption record. This tool will be used to accurately evaluate the iron, folate, and vitamin B12 content of the diet in non-pregnant women of reproductive age who are not currently pregnant. The research will be conducted on 350 women between the ages of 18 and 50 who are of reproductive age (menstruating). A questionnaire will be administered to the volunteer participants, which will consist of sections on general information, dietary habits, frequency of food consumption, and a 24-hour dietary recall.

Detailed Description
The study is planned in three stages. In the first stage, a three-day food consumption record will be taken from 50 non-pregnant (menstruating) women of reproductive age in order to determine the foods to be included in the food consumption frequency section, and the questionnaire sections and questions (nutrition habits and food consumption frequency questionnaire) will be designed. In the second stage of the study, the questionnaire developed in the first stage will be applied to 350 non-pregnant (menstruating) volunteer women of reproductive age through face-to-face interviews. In this stage, the blood parameters of at least 100 individuals whose blood counts have already been taken for routine tests and treatments and who meet the inclusion criteria of the study will also be recorded from their patient files. In the third stage, the questionnaire will be applied again to 75 individuals who have completed the second stage at least 2 weeks later in order to evaluate the reliability of the questionnaire.

Other: Questionnaire
A food frequency questionnaire that was designed to assess folate, iron, and vitamin B12 intake will be administered. Furthermore a 24-hour recall food record will be administered and a complete blood count will be collected. Food frequency questionnaire data will be compared to recall food records and blood count data.
