A Study of the Body's Response to Exercise and a Plant-Based Diet in Overweight Postmenopausal Women With Breast Cancer
Bu çalışma, meme kanseri (breast cancer) olan fazla kilolu, menopoz sonrası kadınlarda vücudun egzersize ve bitki temelli beslenmeye verdiği yanıtı incelemektedir; egzersiz, bitki temelli diyet, fiziksel aktivite ve beslenme danışmanlığı uygulanmaktadır. Çalışmaya, hormon reseptörü pozitif Evre 1-3 meme kanseri olan, aromataz inhibitörü ile idame endokrin tedavisi alan, hareketsiz yaşam süren ve vücut kitle indeksi 27 ve üzeri, 18 yaş ve üzeri kadınlar katılabilmektedir. Faz 2 aşamasında yürütülmekte; şu an katılımcı almamakta ancak devam etmektedir (active, not recruiting).
