The sleep-muscle axis: how poor sleep quality predicts probable sarcopenia in the older adults

Abstract

Aims: Investigate whether there is a link between the quality of sleep and the likelihood of developing sarcopenia in older adults. Methods: Among the 498 patients over 65 who enrolled in the internal medicine geriatrics clinic between December 2024 and March 2025, 74 patients with poor sleep quality (group 1) and 110 patients with good sleep quality (group 2) were included in the study. The remaining 314 patients were excluded from the study. Demographic characteristics, body measurements, comprehensive geriatric assessments, potential sarcopenia assessments, and Pittsburgh sleep quality measurements were conducted. Results: The average age of group 1, consisting of a total of 74 people, is 73.5±5.1 years, and the average age of group 2, consisting of 110 people, is 71.6±5.2 years. A statistically significant difference was detected between the groups in terms of average age distribution (p=0.03). The average body-mass index (BMI) value of group 1 patients was statistically significantly lower than that of group 2 patients (p=0.038). When the comprehensive geriatric evaluation was compared between the groups, the rate of possible sarcopenia was 81 percent in group 1 and 17 percent in group 2 (p<0.034). Conclusion: Findings suggest a potential link between sleep quality and probable sarcopenia in older adults.

Gece korkuları: yaşlanmada uykusuzluk ve sarkopeni arasındaki bağlantı: kesitsel bir çalışma

Abstract

Amaç: Yaşlı yetişkinlerde uyku kalitesi ile sarkopeni gelişme olasılığı arasında bir bağlantı olup olmadığını araştırmak. Yöntemler: Aralık 2024 ile Mart 2025 tarihleri ​​arasında dahiliye geriatri kliniğine kayıtlı 65 yaş üstü 498 hastadan, uyku kalitesi düşük 74 hasta (Grup-1) ve uyku kalitesi iyi 110 hasta (Grup-2) çalışmaya dahil edildi. Geriye kalan 314 hasta çalışmadan çıkarıldı. Demografik özellikler, vücut ölçümleri, kapsamlı geriatrik değerlendirmeler, olası sarkopeni değerlendirmeleri ve Pittsburgh uyku kalitesi ölçümleri yapıldı. Sonuçlar: Toplam 74 kişiden oluşan grup-1'in yaş ortalaması 73,5±5,1 yıl, 110 kişiden oluşan grup-2'nin yaş ortalaması ise 71,6±5,2 yıldır. Gruplar arasında ortalama yaş dağılımı açısından istatistiksel olarak anlamlı bir fark saptandı (p = 0,03). Grup 1 hastalarının ortalama Vücut Kitle İndeksi (VKİ) değeri, Grup 2 hastalarından istatistiksel olarak anlamlı derecede düşüktü (p = 0,038). Gruplar arasında kapsamlı geriatrik değerlendirme karşılaştırıldığında, Grup 1'de olası sarkopeni oranı %81, Grup 2'de ise %17 idi (p < 0,034). Sonuç: Uyku kalitesinin yaşlı kişilerde sarkopeni ile ilişkili olduğu keşfedildi.
