Abstract:
ObjectiveTo investigate the correlation between obstructive sleep apnea syndrome(OSAS) and functional constipation(FC).
MethodsOne hundred and eighty-five patients with OSAS were divided into the observation group(82 OSAS cases complicated with FC) and control group(103 cases).The apnea-hypopnea index(AHI), sleep parameters, sleep structure and body mass index(BMI) were comapred between two groups.
ResultsThe AHI and BMI values in observation group were significantly higher than those in control group(56.9±17.34) vs(32.3±11.09)(P < 0.01).The AD in moderate and severe FC+OSAS group was significantly higher than that in control group (P < 0.01), while minSaO2% was significantly lower than that in control group (P < 0.01).In the moderate(FC+OSAS) group, the proportion of sleep stage 1+2 and respiration-related microarousal index were(79.6±11.7) and (30.1±10.4), respectively, which were significantly higher than those in control group(P < 0.01).In the severe(FC+OSAS) group, the proportion of sleep stage 1+2 and respiration related microarousal index were(82.3±6.7) and (35.3±17.6), respectively, which were significantly higher than those in control group(P < 0.01).The proportions of slow-wave sleep and REM sleep in the moderate and severe (FC+OSAS) groups were(8.2±7.3) and(9.6±2.5) and(6.1±5.2) and(8.7±1.8), respectively, and which were significantly lower than those in control group(P < 0.01).
ConclusionsFC is closely related to OSAS.
