Correlation between sleep quality and quality of life in women with breast cancer

Cilj: Ispitivanje povezanosti kvalitete spavanje i kvalitete života u žena oboljelih od raka dojke, te razlika u doživljaju kvalitete spavanja i kvalitete života u odnosu na dob, vrijeme proteklo od postavljanja dijagnoze i vrstu operativnog zahvata. Ispitanici i metode: Istraživanjem je obuhvaćen uzorak od 96 ispitanica oboljelih od raka dojke. Jednokratno je primijenjen Pittsburgh Sleep Quality Index (PSQI) konstruiran za procjenu kvalitete spavanja u onkoloških bolesnika i FACIT Measurement System - verzija FACT-B konstruirana za populaciju osoba s rakom dojke u svrhu procjene fizičkih, socijalnih, emocionalnih, funkcionalnih i dodatnih determinanti kvalitete života. Rezultati: U uzorku žena obuhvaćanih ovim istraživanjem prisutna je tendencija prema lošijoj kvaliteti spavanja, te nije utvrđena razlika u kvaliteti spavanja u odnosu na kronološku dob, vrijeme proteklo od postavljanja dijagnoze i vrstu oparativnog zahvata. Isto tako, nije dobivena statistički značajna razlika u procjeni kvalitete života u odnosu na vrijeme proteklo od dijagnoze i vrstu operativnog zahvata. U odnosu na kronološku dob utvrđena je statistički značajna razlika između ispitanica u dobi od 31-40 godina i ispitanica u dobi 51-60 godina (p=0,038) pri čemu su ispitanice mlađe dobne skupine imale lošiju kvalitetu života. Također je dobivena statistički značajna povezanost između kvalitete spavanja i kvalitete života (p=0,008), odnosno žene koje su imale lošiju kvalitetu spavanja imale su statistički značajno nižu kvalitetu života. Zaključak: Dobiveni rezultati ukazuju na potrebu provođenja daljnjih istraživanja s ciljem ispitivanja kauzalnih odnosa između kvalitete spavanja i kvalitete života te koncipiranja adekvatnih medicinskih, psihoterapijskih i komplementarno-suportivnih intervencija usmjerenih na ublažavanje psihofizičkog distresa u oboljelih od raka dojke.Aim: The aim of the study was to determine the correlation between sleep quality and quality of life in women with breast cancer, and the difference in sleep quality and quality of life compared to age, the time elapsed since the diagnosis and the type of surgical interventions. Patients and methods: The research was carried out on a sample of 96 participants with breast cancer. Pittsburgh Sleep Quality Index (PSQI) was applied, which was constructed to evaluate the sleep quality of oncology patients. Also, FACIT Measurement System - version FACT-B was applied, constructed for a population with breast cancer to assess physical, social, emotional, functional and additional quality of life determinants. Results: In respondents a tendency towards lower sleep quality is noticed, and there was no difference in sleep quality compared to age, the time elapsed since the diagnosis and the type of surgical interventions. Likewise, no statistically significant difference in the quality of life is obtained compared to the time elapsed since the diagnosis and the type of surgical interventions. In comparison to the age, a statistically significant difference was found between group of 31-40 years old and 51-60 years old (p = 0.038) where the younger group of respondents had poorer quality of life. There was also a statistically significant correlation between sleep quality and quality of life (p = 0.008), i.e. women who had poorer sleep quality had statistically significant lower quality of life. Conclusion: The results emphasize a need for further research of the causal relationships between sleep quality and quality of life. Also, further development of adequate medical, psychotherapeutic and complementary-supportive interventions is stressed, focused to alleviating psychophysical distress in breast cancer patients
