ABSTRACT
Objective:
To investigate the prevalence of chronic constipation in maintenance hemodialysis (MHD) patients and analyze the risk factors of chronic constipation.Methods:
Using the cross-sectional survey method, patients who received MHD in Huadu District People′s Hospital of Guangzhou from September 1, 2021 to September 30, 2021 were enrolled as the research objects. The patient′s demographic, general data and laboratory results were collected. The anxiety level and quality of life were assessed by questionnaires. The patients were divided into constipation group and non-constipation group according to whether they had chronic constipation. The Rome Ⅳ criteria was used to diagnose chronic constipation, and the differences of clinical data between the constipation group and the non-constipation group were compared. The risk factors of chronic constipation in MHD patients were analyzed by logistic regression analysis method.Results:
A total of 321 MHD patients were enrolled in this study, with 168 males, 153 females and age of (59.5±13.4) years old (ranged from 29 to 87 years old). There were 160 patients (49.8%) with chronic constipation. The proportions of males, long dialysis age, taking sevelamer and lanthanum carbonate, diabetic nephropathy, and diabetes in the constipation group were higher than those in the non-constipation group, and the differences between the two groups were statistically significant (all P<0.05). The serum calcium, serum phosphorus, calcium-phosphorus product, anxiety scores, average weekly ultrafiltration volume/dry weight in the constipation group were significantly higher than those in the non-constipation group (all P<0.05), and the serum albumin, serum magnesium, urea clearance index (Kt/V) and geriatric nutritional risk index were significantly lower than those in the non-constipation group (all P<0.05). The results of logistic regression analysis showed that moderate to severe anxiety (moderate, OR=3.233, 95% CI 1.339-7.805, P=0.009; severe, OR=5.103, 95% CI 1.906-13.663, P=0.001), existed risk of nutrition (low risk, OR=3.705, 95% CI 1.440-9.533, P=0.007; moderate risk, OR=5.638, 95% CI 2.557-12.430, P<0.001; severe risk, OR=15.097, 95% CI 4.112-55.436, P<0.001), >60 years old (≤40 years old as a reference, OR=4.050, 95% CI 1.366-12.006, P=0.012), diabetes history ( OR=2.224, 95% CI 1.253-3.946, P=0.006), taking sevelamer ( OR=2.290, 95% CI 1.207-4.346, P=0.011), and calcium-phosphorus product ( OR=1.704, 95% CI 1.329-2.186, P<0.001), intact parathyroid hormone ( OR=1.013, 95% CI 1.003-1.022, P=0.007), blood urea nitrogen ( OR=1.092, 95% CI 1.002-1.189, P=0.045) and serum magnesium ( OR=0.042, 95% CI 0.006-0.294, P=0.001) were the independent influencing factors for chronic constipation in MHD patients.Conclusions:
The prevalence of chronic constipation in MHD patients is 49.8%. Adequate dialysis, improving calcium and phosphorus metabolism, improving nutritional status, relieving anxiety, and increasing serum magnesium level may help to reduce the risk of chronic constipation in MHD patients.
