| dc.description.abstract | Analyze the association of non-specific low back pain and sleep quality with quality of life in adults. Cross-sectional observational analytical study. Data collection via an online questionnaire: Pittsburgh Sleep Quality Index, Nordic Musculoskeletal Questionnaire, and WHOQOL-BREF (World Health Organization Quality of Life Instrument – Abbreviated Version). Data analysis includes the student's t-test, chi-square test, and multiple linear regression (stepwise method). The sample (n = 223) consists mainly of females (76.2%), aged between 33 and 34 years. Significant differences in sleep quality were found between adults with and without nonspecific low back pain (p < 0.05). Sleep quality (p = <.001), body mass index (p = <.001), and low back pain intensity (p = 0.006) are significant predictors of quality of life (adjusted R² = 0.242). This study suggests that adults with nonspecific low back pain have worse sleep quality scores and worse quality of life scores compared to adults without nonspecific low back pain. Female gender and lower levels of education are significantly associated with nonspecific low back pain. Sleep quality, body mass index, and low back pain intensity are significant predictors of quality of life. | eng |
| dc.description.abstract | Analisar a associação da dor lombar não específica e da qualidade do sono com a qualidade de vida, em adultos. Estudo analítico observacional transversal. Recolha de dados através de um questionário online: Índice de Qualidade do Sono de Pittsburgh, Questionário Nórdico-Musculoesquelético e WHOQOL-BREF (World Health Organization Quality of Life Instrument – Abbreviated Version). A análise de dados inclui o teste t student; Qui-Quadrado e regressão linear múltipla (método stepwise). Amostra (n = 223) constituída principalmente pelo sexo feminino (76,2%), com idades entre 33 e 34. Encontradas diferenças significativas da qualidade do sono entre adultos sem e com dor lombar não especifica (p < 0,05). A qualidade do sono (p = <,001), índice de massa corporal (p = <,001), e intensidade da dor lombar (p = 0.006) são preditores significativos da qualidade de vida (R² ajustado = 0,242). Este estudo sugere que adultos com dor lombar não específica apresentam piores scores de qualidade de sono e piores valores nos domínios da qualidade de vida. A qualidade de sono, índice de massa corporal e intensidade da dor lombar são preditores significativos da qualidade de vida. | por |
