Daily behavioral and sleep patterns are associated with aging-induced male-specific disorders in individuals with reduced renal function (vol 16, 111717, 2022)

BACKGROUND:The development of aging-induced male-specific disorders is accelerated by impaired renal function. Although aging-induced male-specific disorders are clinically serious complications in individuals with reduced renal function, their practical management strategies remain obscure. The purpose of this cross-sectional study was to investigate the association between daily behavioral and sleep patterns and aging-induced male-specific disorders in individuals with reduced renal function. METHODS:Eighty men with glomerular filtration rate stage 2-4 (age, 67 ± 9 years), sedentary behavior and physical activity were assessed using a triaxial accelerometer. The mean sleep time was calculated from the sleep time during the accelerometer measurement. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Aging-induced male-specific disorders were assessed using the Aging Males' Symptoms Questionnaire (AMS). RESULTS:A lower moderate to vigorous-intensity physical activity (MVPA) time and a higher PSQI score were independently associated with a higher AMS score. Moreover, when the participants were divided into four groups according to the median MVPA values and the PSQI score (more or less than 6 points), the AMS score was the highest in those with a lower MVPA time and a higher PSQI score. In the mediation analysis, the PSQI score did not mediate a correlation between the MVPA time and AMS score. MVPA time also did not mediate a correlation between the PSQI and AMS scores. CONCLUSIONS:Collectively, these findings suggest that increasing MVPA time and improving sleep quality may contribute to attenuating aging-induced male-specific disorders in individuals with reduced renal function.
