According to the World Health Organization (WHO), quality of life is defined as “the individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals.”
Maailma Terviseorganisatsioonis (WHO) defineeritakse elukvaliteeti kui "indiviidi tajumist oma positsioonis elus, kultuuri ja väärtuste süsteemide kontekstis, milles nad elavad eesmärkide nimel."
