目的 探讨不同体质指数（BMI）分组成年1型糖尿病（T1DM）患者的临床特征以及超重/肥胖与心血管代谢危险因素之间的关系。方法 纳入2015年6月至2022年6月在广州市第一人民医院内分泌代谢科住院的268例成人T1DM患者。分为超重肥胖组（BMI≥24.0 kg/m²，41例）、体质量正常组（18.5≤BMI＜24.0 kg/m²，155例）和体质量过低组（BMI＜18.5 kg/m²，72例）。比较三组人口学、人体测量及代谢指标的差异，采用多元线性回归分析BMI与估算肾小球滤过率（eGFR）的关联。结果 超重肥胖组患者的特征表现为年龄更大、病程更长、体脂肪量更高、腹部皮下脂肪面积更大、腰围、臀围更大、合并高血压比例更高、收缩压更高、高密度脂蛋白胆固醇更低、eGFR更低、糖化血红蛋白（HbA1c）更低。多元线性回归分析显示，校正年龄、性别、病程后，BMI与eGFR呈负相关（β=-2.050，P=0.012）；进一步校正HbA1c、血压、血脂后，该关联不再显著。结论 超重/肥胖成人T1DM患者存在多重代谢异常聚集，BMI与eGFR的负向关联可能主要与血糖、血压、血脂等代谢因素有关。

Objective To investigate the clinical characteristics of adult patients with type 1 diabetes mellitus（T1DM）in different body mass index（BMI）categories and the associations of overweight and obesity with cardiometabolic risk factors．Methods A total of 268 adult T1DM inpatients from Guangzhou First People’s Hospital were enrolled．Patients were divided into three groups：overweight/obese（BMI≥24.0 kg/m²，n=41），normal-weight（18.5≤BMI＜24.0 kg/m²，n=155），and underweight（BMI＜18.5 kg/m²，n=72）．Demographic characteristics，anthropometric measurements，and metabolic parameters were compared among the three groups．Multivariable linear regression analyses were performed to evaluate the association between BMI and estimated glomerular filtration rate（eGFR）．Results Patients in the overweight/obesity group were characterized by older age，longer diabetes duration，higher body fat mass，larger abdominal subcutaneous fat area，greater waist and hip circumferences，a higher prevalence of hypertension，higher systolic blood pressure，lower high-density lipoprotein cholesterol levels，lower eGFR，and lower glycated hemoglobin（HbA1c）levels．Multivariable linear regression analysis demonstrated that BMI was inversely associated with eGFR after adjustment for age，sex，and diabetes duration（β=-2.050，P=0.012）．However，this association was no longer significant after further adjustment for HbA1c，blood pressure，and lipid parameters．Conclusions Overweight/obese adult T1DM patients exhibit clustering of metabolic abnormalities．The negative association between BMI and eGFR may be primarily mediated by metabolic factors such as hyperglycemia，hypertension，and dyslipidemia．

       目的 探讨肌少症性肥胖（SO）诊断标准的演进及其在中国老年人群中的本土化综合干预路径。方法 评述ESPEN/EASO最新共识，结合我国老年人代谢特征，系统分析“筛查-诊断-分期”流程及运动营养协同干预的临床效能。结果 SO诊断核心在于识别“隐性肥胖”，建议在AWGS2019标准基础上，叠加中国特异性腰围切点（男≥90 cm，女≥85 cm）或体脂率指标，并应用ALM/BMI校正肌肉质量。研究证实，以渐进式抗阻训练联合高蛋白营养（1.2~1.5 g·kg-1·d-1）为核心的协同模式，通过激活mTOR通路可显著逆转肌肉流失并改善胰岛素抵抗。融入八段锦等传统功法及乳清蛋白补充，能有效重塑中国患者“高碳水、低蛋白”的膳食习惯，提升依从性。结论 构建护士主导、社区依托的多学科管理模式，并借助远程健康工具实现闭环监测，是提升我国SO精准诊疗水平的关键路径。

      Objective To explore the evolution of diagnostic criteria for sarcopenic obesity（SO）and its localized comprehensive intervention pathways tailored to the metabolic characteristics of the Chinese elderly population．Methods The latest ESPEN/EASO consensus was reviewed．Combined with the metabolic profile of Chinese older adults，the “screening-diagnosis-staging” workflow and the clinical efficacy of synergistic exercise and nutrition interventions were systematically analyzed．Results The core of SO diagnosis lies in identifying “hidden obesity．”It is recommended to incorporate Chinese-specific waist circumference cut-offs（male≥90 cm，female≥85 cm）or body fat percentage into the AWGS2019 framework，utilizing ALM/BMI for muscle mass calibration．Evidence suggests that a synergistic model，centered on progressive resistance training（PRT）and high-protein nutrition（1.2~1.5 g·kg-1·d-1），can significantly reverse muscle loss and improve insulin resistance by activating the mTOR pathway．Integrating traditional Chinese exercises（e. g. ，Baduanjin）and whey protein supplementation effectively reshapes the “high-carbohydrate，low-protein” dietary habits of Chinese patients，thereby enhancing intervention adherence．Conclusions Establishing a nurse-led，community-based multidisciplinary management model，integrated with digital health tools for closed-loop monitoring，is a pivotal strategy for enhancing the precision of SO diagnosis and treatment in China．

       目的 探讨肥胖与肺功能参数的相关性。方法 将90例接受肺功能检查的患者依据体质指数（BMI）分为肥胖组（BMI≥25 kg/m²，n=50）和正常体质量组（18.5 kg/m²＜BMI≤24.9 kg/m²，n=40），比较两组各项肺功能参数的差异，包括肺通气功能的参数如［用力肺活量（FVC）、第1秒用力呼气容积（FEV₁）、1秒率（FEV₁/FVC）、最大呼气流量（PEF）］以及反映小气道功能的参数［50%最大呼气流量（MEF₅₀），25%最大呼气流量（MEF₂₅）］；比较肥胖组不同性别间上述肺功能参数的差异及其与腰围（WC）与BMI的相关性。结果 肥胖组FVC、FEV₁、FEV₁/FVC、MEF₅₀、MEF₂₅低于正常体质量组（P＜0.01）；肥胖组中男性FVC及FEV₁低于女性（P＜0.01）。相关分析结果显示，肥胖组中WC与BMI均与肺功能多个参数呈负相关趋势，其中WC的负相关趋势更突出，且与FVC呈负相关关系（P＜0.05）。结论 肥胖影响反映肺功能的多个参数，表现为肺通气功能和小气道功能多个指标水平降低，且肥胖男性更甚；在肥胖人群中，相较于BMI，WC与FVC的关系更密切。

      Objective To investigate the correlation between obesity and pulmonary function parameters．Methods Ninety patients undergoing pulmonary function testing were categorized into an obese group（BMI≥25 kg/m²，n=50）and a normal-weight group（18.5 kg/m²＜ BMI≤24.9 kg/m²，n=40）．Differences in pulmonary function parameters were compared between groups，including ventilatory parameters（forced vital capacity［FVC］，forced expiratory volume in 1 second［FEV₁］，FEV₁/FVC ratio，peak expiratory flow［PEF］） and parameters reflecting small airway function（maximum expiratory flow at 50% of forced expiratory volume［MEF₅₀］，and 25% maximum expiratory flow［MEF₂₅］）．Differences in these pulmonary function parameters between genders within the obese group and their correlations with waist circumference（WC）and BMI were also assessed．Results FVC，FEV₁，FEV₁/FVC，MEF₅₀，and MEF₂₅ were significantly lower in the obese group compared to the normal-weight group（P＜0.01）．Among obese subjects，male FVC and FEV₁ were significantly lower than female values（P＜0.01）．Correlation analysis revealed negative correlations of WC and BMI with multiple pulmonary function parameters in the obese group，with WC exhibiting a more pronounced negative correlation and a significant negative relationship with FVC（P＜0.05）．Conclusions Obesity impacts multiple parameters reflecting lung function，manifesting as reduced levels of several indicators of pulmonary ventilation and small airway function，with male obese individuals exhibiting greater impairment．Within the obese population，WC correlates more closely with FVC than BMI．

       目的 探究体成分变化对肥胖患者肾小球高滤过的影响。方法 根据纳入排除标准，连续收集在中南大学湘雅二医院营养科及代谢内分泌科就诊的肥胖患者（体质指数≥28 kg/m²），对其随访3个月以上，纳入体质量减轻≥5%的患者，记录一般人口学、人体测量学、体脂率（BFP）、体脂肪量（BFM）、内脏脂肪面积（VFA）和骨骼肌量（SMM）等体成分和实验室检验数据，计算估计肾小球滤过率（eGFR）。肾小球高滤过被定义为eGFR大于普通人群第95个百分位数，根据此标准分为肾小球高滤过组和正常滤过组，比较组间一般人口学资料、生化指标及体成分的差异，绘制限制性立方样条图分析体成分的变化与eGFR变化之间的非线性关联。结果 （1）共收集85例肥胖患者初复诊资料，其中肾小球正常滤过患者43例，肾小球高滤过患者42例，男性35例，女性50例；（2）单因素分析提示肾小球高滤过患者减重前后eGFR差异有统计学意义［143.34 mL/（min·1.73 m²） vs 125.68 mL/（min·1.73 m²）；（3）非线性相关分析结果显示肥胖肾小球高滤过患者eGFR的变化与VFA的变化相关（P=0.015 1），与BFP的变化相关（P=0.022 6）。结论 肥胖患者减重后，随着VFA和BFP的下降可能改善肾小球高滤过。

    Objective This study aimed to investigate the impact of alterations in body composition on glomerular hyperfiltration in obese patients．Methods According to predefined inclusion and exclusion criteria，obese patients（body mass index ≥28 kg/m2）from the department of clinical nutrition and the department of metabolism and endocrinology at Second Xiangya Hospital of Central South University were consecutively enrolled．Patients who achieved a weight loss of ≥5% after more than three months of follow-up were included．Data on general demographics，anthropometric measurements，body composition parameters-including body fat percent（BFP），body fat mass（BFM），visceral fat area（VFA），and skeletal muscle mass（SMM）-and laboratory test results were collected．The estimated glomerular filtration rate（eGFR）was calculated．Glomerular hyperfiltration was defined as an eGFR greater than the 95th percentile for the general population．Based on this criterion，patients were categorized into a hyperfiltration group and a normofiltration group．Differences in demographic characteristics，biochemical indices，and body composition parameters between the two groups were compared．Restricted cubic spline curves were plotted to analyze the non-linear relationship between changes in body composition and changes in eGFR．Results （1）A total of 85 obese patients（35 males and 50 females） with initial and follow-up data were included，comprising 43 patients with normofiltration and 42 with hyperfiltration；（2）Univariate analysis indicated a statistically significant difference in eGFR before and after weight loss in the hyperfiltration group（143.34 mL/min/1.73m² vs 125.68 mL/min/1.73m²，P＜0.001）；（3）Non-linear correlation analysis revealed that changes in eGFR among obese patients with hyperfiltration were significantly associated with changes in VFA（P=0.015 1）and changes in BFP（P=0.022 6）．Conclusions Weight loss in obese patients may ameliorate glomerular hyperfiltration，potentially mediated through reductions in VFA and BFP．

目的 研究高尿酸（UA）和肥胖的交互作用对非酒精性脂肪肝病（NAFLD）患病率的影响。方法 采用病例对照的研究法,选取2021年1月至2021年12月兰州市某医院健康体检中心进行常规健康体检的504人为研究对象,按照诊断标准分为NAFLD组187人和非NAFLD 组317人。采用Logistic 回归模型、相乘、相加交互模型探讨非酒精性脂肪肝病患病风险的影响因素及因素间的交互作用。结果 多因素条件Logistic回归分析可知,肥胖（OR=4.87,95%CI：3.01~7.89）,糖尿病患者（OR=3.40,95%CI：1.51~7.68）,幽门螺杆菌（Hp）携带者（OR=1.62,95%CI：1.03~2.57）,高尿酸血症的NAFLD患病风险增加,分别是正常者、非糖尿病患者、非Hp携带者,非高尿酸血症的4.87倍,3.40倍,1.62倍,2.28倍,在调整混杂因素后交互作用结果显示,高尿酸血症和肥胖对NAFLD患病率有相乘交互作用（OR=0.30,95%CI：0.10~0.88,P=0.029）、但无相加交互作用（相对超额危险度比=3.15、归因比=0.24、协同指数=1.34）。结论 BMI、糖尿病、Hp是NAFLD患病的独立危险因素,其中高尿酸血症和超重与肥胖对NAFLD患病有相乘交互作用,无相加交互作用。

Objective To explore the influence of the interaction of high uric acid（UA）and obesity on the prevalence of non-alcoholic fatty liver disease（NAFLD）．Methods Using a case-control study method,504 people who underwent routine health checkups at the health checkup centre of a hospital in Lanzhou City from January 2021 to December 2021 were enrolled in the study,and 187 people were included in the NAFLD group and 317 people in the non-NAFLD group according to the diagnostic criteria．Logistic regression models,multiplicative and additive interaction models were used to investigate the factors affecting the risk factors of NAFLD and the interaction between the factors．Results Multifactorial conditional logistic regression analysis showed that the risk of NAFLD was increased in obese（OR=4.87,95% CI：3.01-7.89）,diabetic patients（OR=3.40,95% CI：1.51-7.68）,Helicobacter pylori（Hp）carriers（OR=1.62,95% CI：1.03-2.57）;the increased risk of NAFLD prevalence in hyperuricaemia patients was 4.87,3.40,1.62,and 2.28 times higher than that of normal,non-diabetic,non-Hp carriers,and non-hyperuricemic individuals,respectively．And the adjusted interaction showed a multiplicative interaction of hyperuricaemia and obesity on the prevalence of NAFLD after controlling for the confounders（OR=0.30,95% CI：0.10-0.88,P=0.029）,but no additive interaction （relative excess risk due to interaction=3.15,attributable proportion due to interaction=0.24,and synergy index=1.34） interactions．Conclusions BMI,diabetes mellitus,and Hp were independent risk factors for the prevalence of NAFLD,with hyperuricaemia and overweight and obesity having multiplicative interaction and no additive interaction．

目的 比较早产胎膜早破(PPROM)≥34周的肥胖孕妇与非肥胖孕妇的早产儿住院结局。方法 回顾性分析2016年1月—2020年12月在本院出生并入住新生儿科的所有出生胎龄≥34周的PPROM早产儿。根据孕妇分娩时体质量指数(BMI),分为肥胖组(BMI≥30 kg/m²)和非肥胖组(BMI＜30 kg/m²),比较2组间的一般情况、妊娠结局及所生晚期早产儿的住院结局,组间比较采用两独立样本t检验及χ²检验。结果 与非肥胖孕妇相比,肥胖孕妇的晚期早产儿分娩后呼吸道并发症发病率高,主要表现为新生儿呼吸窘迫综合征,辅助通气、吸氧和表面活性物质的使用、败血症、感染性肺炎发病率高,母亲妊娠期糖尿病发病率增高,差异均具有统计学意义(P＜0.05),其余新生儿高胆红素血症、新生儿坏死性小肠结肠炎、脑室内出血、早产儿支气管肺发育不良等并发症比较无统计学意义(P＞0.05)。结论 PPROM≥34周的肥胖孕妇与非肥胖孕妇相比,所生晚期早产儿呼吸道并发症和败血症等不良结局的发生率增加。

Objective To compare the hospitalization outcomes of 34 weeks or over preterm infants with preterm premature rupture of membranes (PPROM) in obese and non-obese pregnant women. Methods A retrospective analysis of PPROM preterm infants born in our hospital and admitted to the neonatology department from January 2016 to December 2020 with a gestational age of 34 weeks or over was carried out. According to the pregnant women's body mass index (BMI) at delivery, they were divided into obese group (BMI≥30 kg/m²) and non-obese group (BMI<30 kg/m²). The general conditions, pregnancy outcomes and late premature infants hospitalization outcomes between the two groups were compared using two independent samples t test and χ² test. Results Compared with non-obese pregnant women, the incidence of respiratory complications after delivery in late preterm infants of obese pregnant women was higher, mainly manifested as high incidence of neonatal respiratory distress syndrome, assisted ventilation, oxygen inhalation and the use of surfactants, sepsis, and pneumonia, also maternal gestational diabetes incidence was increased, and the differences were statistically significant (P<0.05); other complications of neonatal hyperbilirubinemia, necrotizing enterocolitis, intraventricular hemorrhage, bronchopulmonary dysplasia were not statistically significant (P>0.05). Conclusions Compared with non-obese pregnant women with 34 weeks or over PPROM, obese pregnant women had an increased incidence of adverse outcomes in late preterm infants such as respiratory complications and sepsis.

目的 探讨2型糖尿病（T2DM）患者慢性肾脏病（CKD）发生的危险因素以及其与肥胖之间的相关性。方法 选择2019年3月—2021年12月我院收治的552例T2DM患者作为研究对象,根据是否发生CKD进行分组,其中合并CKD患者136例、未合并CKD患者416例,对2组患者的一般资料及实验室指标进行单因素回归分析比较;对于未合并CKD的T2DM患者进行为期1年的随访,统计T2DM患者CKD的发生率,并针对随访群体的一般资料及实验室指标进行对比分析,通过单因素Logistic回归分析患者发生CKD的影响因素,了解T2DM患者CKD的发生与肥胖之间的关系。结果 合并CKD和未合并CKD的T2DM患者间的年龄、病程、肝功能指标、血脂指标中的低密度脂蛋白胆固醇（LDL-C）、高密度脂蛋白胆固醇（HDL-C）、肾功能指标中的尿酸、肾小球滤过率（eGFR）比较差异均无统计学意义（均P>0.05）,组间在性别构成、BMI、血压、白蛋白、血红蛋白、血脂指标中的总胆固醇（TC）及甘油三酯（TG）、血糖及肾功能指标中尿白蛋白/肌酐比（UACR）比较差异均有统计学意义（均P<0.05）。396例未合并CKD的T2DM患者随访结果显示,随访期间发生CKD患者123例、未发生CKD患者293例,组间的性别构成、BMI、舒张压、血红蛋白、丙氨酸氨基转移酶、白蛋白、总胆红素、TC、LDL-C、HDL-C、尿酸、糖化血红蛋白及eGFR比较差异均无统计学意义（均P>0.05）,而组间年龄、病程、收缩压、天冬氨酸氨基转移酶、TG、空腹血糖（FPG）及UACR比较差异均有统计学意义（均P<0.05）。单因素Logistic回归分析结果显示,T2DM患者发生CDK的独立危险因素包括肥胖和收缩压、TG及FPG等指标升高（P<0.05）。T2DM患者的BMI与CKD的发生有关,当患者的BMI在28~31 kg/m²之间时,其CKD的发生率明显增加。结论 T2DM患者的CKD发生与肥胖因素有一定相关性,危险因素包括肥胖、血脂血压血糖异常等,T2DM患者的BMI在28~31 kg/m²之间时,其发生CKD的风险会有所增加,故需要对患者的BMI进行有效控制,降低CKD发生率,以避免病情恶化。
