BACKGROUND: Clinical trials concerning the effect of supplements or multivitamin on improving
the quality of life have proven different results. The present study was conducted to examine the
effect of multivitamin supplement on quality of life of the elderly.
MATERIALS AND METHODS: Sixty‑four old people over 65 years of age in Kermanshah Elderly Care
Center participated in this randomized trial. The samples were first selected using the convenience
sampling and then were randomly assigned into intervention and control groups. The intervention
group received one multivitamin mineral (MVM) supplement capsule every day for 3 months with
no intervention for the control group. Standard quality of life questionnaire was used to collect the
data. Data were analyzed using the SPSS software version 22.
RESULTS: The mean age of the participants was 70.77 ± 8.29 years. The results of intra‑group
evaluation of the aspects of quality of life of the elderly show the lack of significant changes in the mean
scores of physical health and environmental health of the elderly in the intervention group (P > 0.05)
and the significant reduction of these aspects in the control group (P < 0.05) after intervention. The
mean score of mental health scores in the intervention group significantly increased (P = 0.01),
but there are no significant changes in the control group (P = 0.273). The mean scores of social
relationships as well as the overall score of quality of life in the intervention and control groups
showed no significant changes (P > 0.05).
CONCLUSION: The present study showed that the consumption of MVM supplements can have
a positive effect on increasing the quality of life of the elderly, but it is recommended to be done in
the long term along diet. Moreover, considering the fact that no change was observed in the other
aspects of the quality of life, attentions should be paid to the environmental and social factors such
as social supports and empowerment of the old people in the future studies.
