夜尿与睡眠不满意相关的因素：基于社区的横断面研究及可解释机器学习分析

Abstract Background Nocturia is associated with poor sleep quality, but its relationship with subjective sleep dissatisfaction remains insufficiently understood. In primary care, sleep-related complaints are common, and nocturia may be overlooked as a contributor to sleep dissatisfaction. This study examined the association between nocturia and sleep dissatisfaction and explored age-related differences using explainable machine learning. Methods We conducted a community-based cross-sectional postal survey in 2022 among 10,000 randomly selected residents of Tsukuba City, Japan, aged 45–89 years
