Quick Summary

In this randomized controlled trial among women receiving chemotherapy for breast cancer, nightly supplementation with melatonin, compared to a placebo, did not reduce fatigue or improve well-being to a statistically significant degree.

What was studied?

The effects of melatonin supplementation and Mediterranean diet adherence on cancer related fatigue and well-being among women receiving chemotherapy treatment for breast cancer.

The primary outcome was cancer-related fatigue and well-being, as measured using the Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT) questionnaire. The FACIT questionnaire includes a fatigue subscale, as well as subscales of physical, social, emotional, and functional well-being.

Mediterranean diet (MD) adherence was assessed using the MedDietScore calculator, which includes the frequency and amount of consumed MD foods such as unrefined grains, potatoes, vegetables, fruits, legumes, fish, and olive oil.

Physical characteristics such as height, weight, waist circumference, and BMI were assessed, and blood samples were collected to assess lipid profiles, inflammatory markers, and glucose levels.
