Salt Intake, BMI, and Cardiometabolic Risk in a Beijing Occupational Cohort

Data Sheet 1_Salt intake moderates the association between BMI and cardiometabolic risk contains data from a cross-sectional study of 1,866 adults in Beijing. The dataset, authored by Jiaju Ren and last updated in April 2026, likely includes estimated daily salt intake, body mass index, and seven cardiometabolic indicators such as HDL-C and uric acid.

Use Cases

• Modeling the non-linear relationship between BMI and cardiometabolic markers based on the described inflection points.
• Investigating the moderating effect of daily salt intake on metabolic associations, as described in the study results.
• Analyzing sex-specific thresholds for salt intake's influence on metabolic indicators like HDL-C and ApoA1.
• Examining age-related differences in the salt-BMI interaction, particularly between younger and elderly populations.

Strengths

• Includes data from 1,866 adult participants, providing a substantial sample size.
• Contains multiple cardiometabolic indicators (e.g., HDL-C, uric acid, ApoA1) and estimated daily salt intake.
• Analysis identified specific, sex-dependent salt intake threshold ranges (e.g., 13–16 g/d for men, 11–12 g/d for women).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cross-sectional occupational cohort in Beijing, which may limit generalizability.
