Sleep Quality Components as Predictors of Health-Related Quality of Life Domains among Primigravida in Ibadan, Nigeria

Background and Objective: Pregnancy and childbirth are periods of great joy and delicate, interesting, and exciting aspects of women’s life. The study investigates whether sleep quality components will predict health-related quality of life (HRQOL) domains among primigravidas. 
 Materials and Methods: The study employed descriptive research design. 768 primigravidas, attending antenatal care in nine purposively-selected government hospitals in Ibadan, Nigeria, which fulfilled the inclusion criteria participated in the study. A questionnaire consisting of demographic information of primigravidas, World Health Organization Quality of Life-BREF (WHOQOL-BREF), and Pittsburgh Sleep Quality Index (PSQI) with reliability coefficient of 0.89 and 0.85, respectively, were used to collect data. Six hypotheses were tested using multiple regression analysis (MRA) and analysis of variance (ANOVA). 
 Results: Sleep quality components had a statistical, joint influence on HRQOL domains (physical health domain, F = 4.526, P < 0.01; psychological domain, F = 2.931, P < 0.05; and environment domain, F = 2.788, P < 0.05) of primigravidas in Ibadan. In addition, domains of HRQOL were significantly influenced by primigravidas’ marital status (F = 3.591, P < 0.05). 
 Conclusion: Effective management of sleep quality components during pregnancy can improve HRQOL domains of primigravidas. Researchers recommended that antenatal care lectures for primigravidas should be reinforced with emphasis on the sleep quality and its influence on their HRQOL domains for better wellness of the primigravidas.
