Effect of the LEARNS psychological care model in weight management of patients with obese polycystic ovary syndrome

Objective To investigate the effect of the LEARNS psychological care model in weight management of patients with obese polycystic ovary syndrome (PCOS). Methods A total of 75 obese PCOS patients admitted to the obesity clinic of a tertiary comprehensive hospital in Tianjin from March 2021 to December 2023 were selected as the research subjects. They were divided into a control group of 40 cases and an observation group of 35 cases using the coin toss method. The control group received routine weight loss treatment, while the observation group received LEARNS psychological nursing interventions on the basis of routine weight loss treatment. Primary indexes were body weight/Body Mass Index (BMI), Body Fat Percentage(FBP), Visceral Fat Area(VFA), assessment on dietary and exercise behavior, psychological evaluation and metabolic indicators. Results After implementation of LEARNS psychological nursing interventions, patients of both observation group and control group received better outcomes of body weight /BMI, FBP, VFA, dietary and exercise behavior assessment, psychological evaluation and metabolic indicators. There was a significant difference in changes of following indexes: decrease in body weight, FBP, VFA and BMI; increase in scores of dietary and exercise behavior assessment; decrease in scores of The Generalized Anxiety Disorder Questionnaire (GAD-7) and the Patient Health Questionnaire (PHQ-9) ; decrease in Biochemical indicators related to obesity such as total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), uric acid(UA), glycosylated hemoglobin A1c、alanine aminotransferase(ALT)(P＜0. 05). Patients in the observations group had a higher level of high-density lipoprotein cholesterol(LDL-H) and lower level of aspartate aminotransferase (AST) and triglyceride(TG) compared with those before intervention(P＜0. 05). Conclusion The LEARNS psychological care model can promote weight management in obese PCOS patients, resulting in significant improvements in dietary and exercise habits and behaviors, psychological status, and metabolic indicators in obese PCOS patients, without increasing the incidence of adverse reactions. (目的 分析LEARNS心理护理模式对肥胖型多囊卵巢综合征(PCOS)患者体重管理的影响。方法 选取天津市某三甲综合医院肥胖门诊2021年3月—2023年12月接收的75例肥胖型PCOS患者为研究对象, 采用抛硬币法分为对照组40例和观察组35例。对照组给予常规减重治疗方案, 观察组在常规减重治疗方案基础上给予LEARNS心理护理模式干预。监测患者干预前后的体重/体质指数(BMI)、内脏脂肪面积(VFA)、饮食习惯/运动习惯评分、心理评价和代谢指标。结果 干预后观察组和对照组患者的BMI、体脂率(FBP)、VFA、饮食/运动行为改善、心理评价和代谢指标较干预前改善。LEARNS心理护理模式干预后, 两组患者的体重、体脂率(FBP)、VFA、BMI均显著降低, 饮食习惯得分、运动习惯得分显著增加, 广泛性焦虑量表(GAD-7)和9项患者健康问卷(PHQ-9)评分均显著降低; 肥胖相关的生化指标总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、尿酸(UA)、糖化血红蛋白(HbA1c)、丙氨酸氨基转移酶(ALT)均显著降低, 差异有统计学意义(P＜0. 05)。观察组中还可观察到显著的HDL-C升高, AST和TG下降, 差异有统计学意义(P＜0. 05)。结论 LEARNS心理护理模式能提升肥胖型PCOS患者体重管理效果, 有效改善PCOS患者饮食习惯、运动习惯、心理状态和相关代谢指标水平, 且不增加不良反应, 值得借鉴。)
