摘要:
目的 了解中青年维持性血液透析(MHD)患者体力活动水平,分析中青年MHD患者体力活动水平的影响因素。 方法 选取2020年5—12月南阳市4所医院血液净化科的267例中青年MHD患者,使用基本资料调查问卷和国际体力活动量表(IPAQ)中文版短问卷收集相关资料,分析体力活动水平,并运用多因素logistic回归分析研究其影响因素。 结果 共调查267例MHD患者,体力活动充足81例,占30.34%,体力活动不足186例,占69.66%;随着透析龄的延长,体力活动不足构成比逐渐增加(Z=5.459,P<0.001)。多因素logistic回归分析结果显示,透析龄(OR=1.726,P=0.002)、家庭月收入(OR=1.213、1.457,均P<0.001)、透析频率(OR=1.572,P<0.001)、透析模式(OR=1.425,P<0.001)、营养水平(OR=1.253,P<0.001;OR=0.634,P=0.021)、合并症指数(OR=1.715,P<0.001)、血肌酐水平(OR=1.919,P<0.001)、血尿素氮水平(OR=1.895,P<0.001)、血红蛋白水平(OR=1.172,P=0.004)、血钙水平(OR=0.435,P=0.038)、脑钠肽水平(OR=3.186,P<0.001)是中青年MHD患者体力活动水平的影响因素(均P<0.05)。 结论 MHD患者是体力活动水平不足高危人群,体力活动水平主要受透析充分性、营养水平、透析频率及模式、家庭经济水平和合并症等因素影响,提示临床应重视MHD患者营养和体力活动水平评估和干预。 Abstract:Objective To explore the level of physical activity of young and middle-aged maintenance haemodialysis (MHD) patients and analyse its influencing factors. Methods A total of 267 young and middle-aged patients with MHD treated in the blood purification department of four hospitals in Nanyang from May to December 2020 were enrolled. The basic data questionnaire and the international physical activity questionnaire (IPAQ) were used in collecting relevant data and analysing the level of physical activity, and influencing factors were examined through multiple-factor logistic regression analysis. Results A total of 267 cases of MHD were investigated: 81 cases were adequately physically active (30.34%), and 186 cases were insufficiently physically active (69.66%). As dialysis age increased, the proportion of insufficient physical activity gradually increased (Z=5.459, P < 0.001). The results of multivariate logistic regression analysis showed that dialysis age (OR=1.726, P=0.002), family monthly income (OR=1.213, 1.457, all P < 0.001), dialysis frequency (OR=1.572, P < 0.001), dialysis mode (OR=1.425, P < 0.001), nutritional level (OR=1.253, P < 0.001; OR=0.634, P=0.021), comorbidity index (OR=1.715, P < 0.001), blood creatinine level (OR=1.919, P < 0.001), blood urea nitrogen level (OR=1.895, P < 0.001), hemoglobin level (OR=1.172, P=0.004), blood calcium level (OR=0.435, P=0.038) and brain natriuretic peptide level (OR=3.186, P < 0.001) were influential factors of physical activity of young and middle-aged patients with MHD (all P < 0.05). Conclusion Patients with MHD consitute a high-risk group of insufficient physical activity. The level of physical activity is mainly affected by adequacy of dialysis, nutritional level, frequency and mode of dialysis, family economics and comorbidities. It is suggested that the evaluation and intervention of nutrition and physical activity in MHD patients should be emphasized. -
