Detailed questionnaire
The authors carried out their investigations with a sample of 532 subjects, providing them with a structured questionnaire in order to obtain data on demographics, socioeconomic information, the presence of morbidities as well as lifestyle and anthropometric characteristics. Food intake was evaluated using two 24-hour dietary recalls and a Food Frequency Questionnaire.
Female sex, non-smokers and high level of education
Approximately 60% of the subjects were classified as yogurt consumers. In the logistic regression model, yogurt intake was associated with smoking, the female sex and the 20-39 age group. The quantity of yogurt consumed is higher among non-smokers and higher-income subjects. However, the level of education of the head of the household is inversely associated with the quantity of yogurt consumed.
