Detailed Description

Frequency of 5 food groups will be asked in dish-based semi-quantitative food frequency questionnaire and they would be converted to grams. GI and GL will be estimated by using international table of GI and GL.

Validated Iranian versions of Hospital Anxiety and Depression Scale and General Health Questionnaire (GHQ)-12 were used to assess anxiety, depression and psychological distress.

Possible score range for anxiety and depression is from 0 to 21. Scores of 8 or higher on either section were considered as the presence of anxiety or depression and scores of 7 or less were considered as normal status.
