This dataset contains the minimal anonymized data necessary to replicate the findings of the study titled "Metabolic Syndrome, Social Isolation, and Sarcopenia in Mild Cognitive Impairment: A Multi-Faceted Analysis of Risk Factors and Mediating Pathways" (Manuscript ID: PONE-D-25-33355). The data were collected from a cohort of older adults in rural and urban settings, with variables spanning four critical domains:1. Demographics: Age, gender, residence type (rural/urban), marital status, education level2. Lifestyle Factors: Smoking history, alcohol consumption frequency3. Health Outcomes:- Mild cognitive impairment (MCI) status- Social isolation (binary) and social score (continuous)- Sarcopenia indicator (ASM, Appendicular Skeletal Muscle Index)4. Metabolic and Physiological Markers:- Metabolic syndrome components (METS-IR, VAI, AIP, nHDL)- Residual cholesterol, eGFR (kidney function)- Frailty index (continuous) and frailty status (binary)Key features:- Contains individual-level records with unique household identifiers- Supports analysis of mediation pathways between metabolic health, social factors, and sarcopenia in MCI- Variables are coded with clear value labels (e.g., 1="Married", 0="No" for smoking)- Curated for reproducibility of regression and mediation models in the associated manuscript<br>Format: CSV files.Ethics: Data are fully anonymized; no direct identifiers are present.Sample size:N=21,095participants.

本数据集包含复现题为《轻度认知损害患者的代谢综合征、社会隔离与肌肉减少症：危险因素及中介通路的多维度分析》（稿件编号：PONE-D-25-33355）的研究结果所需的最小匿名化数据。
该数据采集自城乡社区的老年人群队列，涵盖四大核心领域的变量：
1. 人口学特征：年龄、性别、居住类型（农村/城市）、婚姻状况、受教育水平
2. 生活方式因素：吸烟史、饮酒频率
3. 健康结局：
- 轻度认知损害（Mild Cognitive Impairment, MCI）状态
- 社会隔离（二分类）与社会评分（连续型）
- 肌肉减少症指标：四肢骨骼肌质量指数（Appendicular Skeletal Muscle Index, ASM）
4. 代谢与生理标志物：
- 代谢综合征组分（METS-IR、VAI、AIP、nHDL）
- 残余胆固醇、估算肾小球滤过率（estimated Glomerular Filtration Rate, eGFR，肾功能指标）
- 衰弱指数（连续型）与衰弱状态（二分类）

核心特性：
- 包含带有唯一家庭标识符的个体水平记录
- 可用于分析轻度认知损害患者中代谢健康、社会因素与肌肉减少症之间的中介通路
- 变量均配有清晰的取值标签（例如：1="已婚"，0="无吸烟史"）
- 经精心整理以确保关联稿件中回归与中介模型的可复现性
