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 level 2. Lifestyle Factors: Smoking history, alcohol consumption frequency 3. 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 Format: CSV files. Ethics: Data are fully anonymized; no direct identifiers are present. Sample size:N=21,095participants.
