Background and aims: Diabetes affects all physical, emotional, and psychological aspects of patient’s health. Postmenopausal diabetic women are more susceptible due to their crucial conditions. The emotional regulatory role of vitamin D may be because of the existence of its receptors distributed in brain areas involved in emotional processing and affective disorders. The aim of this study is to assess the effect of ۳-mounth regular consumption of vitamin D-fortified low fat yogurt on QOL indices in diabetic postmenopausal women. Methods: Fifty nine postmenopausal diabetic women randomly allocated to the ‘FY’ (received vitamin D-fortified low fat yogurt, containing ۲۰۰۰ IU vitamin D in ۱۰۰ g) or ‘PY’ (received plain low fat yogurt without additive) treatment groups. The quality of life questionnaire SF-۳۶ which is the most widely used method to assess the QOL was used before and after the intervention. Results: After the ۳-month intervention, physical performance, vitality, and mental health scores significantly increased and the score of physical pain decreased in the FY group. In the PY group, physical performance, vitality, and emotional role scores significantly decreased. Final scores of physical performance and vitality significantly increased in the FY group compare to the PY group while physical? Conclusion: Three months daily consumption of ۲۰۰۰ IU vitamin D fortified low-fat yogurt improved physical performance, physical pain, and vitality while the other domains of QOL assessments did not show significant changes.
