Título
Effects of sleep quality on postural stability maintenance: a cross-sectional study with elderly individuals.
Introdução
Postural stability is a function that depends on complex systems subject to multifactorial declines related to both aging and pathologies or issues arising from an individual's lifestyle.
Objetivo
To analyze the association between sleep conditions and postural stability in individuals aged ≥ 60 years
Métodos
Cross-sectional study with 167 individuals attending the Basic Health Units (UBS) in the city of Santa Bárbara d’Oeste, São Paulo, Brazil. Sociodemographic and clinical parameter questionnaires were administered. For sleep analysis, the Pittsburgh Sleep Quality Index (PSQI) was used; for physical activity, the International Physical Activity Questionnaire was employed; and for strength, the manual grip strength test was used. Anthropometric measurements of waist and hip circumference were utilized to assess nutritional status, and balance was analyzed using the Berg Balance Scale.
Resultados
The sample consisted of 167 elderly individuals with an average age of 72.7 ± 7.0 years, the majority being women (67.7%), aged between 70 and 79 years (49.1%), with an average of 6.7 ± 4.5 years of schooling. Most participants had poor sleep quality (76%), did not meet the physical activity guidelines of ≥ 150 minutes of moderate activity per week (55.1%), were overweight (61.7%), and exhibited cardiovascular risk both by waist circumference measurements (79%) and by the waist-to-hip ratio (75.4%), in addition to low manual grip strength (19.8%). Logistic regression results for factors associated with postural control, evaluated by the Berg Balance Scale adjusted for age (p<0.05), showed that a higher PSQI score (> 5 points) indicated a greater likelihood of poor balance (7.34; OR = 0.89; p = 0.027). Regarding other variables, higher waist circumference (94.15; OR = 0.95; p = 0.003), lower handgrip strength (26.26; OR = 1.09; p = 0.010), and individuals who engaged in less physical activity (65.22%; OR = 2.82; p = 0.036) also demonstrated poor balance.
Conclusões
The findings of this study highlight the impact of sleep quality and clinical health conditions on maintaining Postural stability. Evidence suggests that maintaining postural stability in the elderly is multifactorial and should be carefully studied by different areas of knowledge.
