Medical Intern Health Metrics: One-Year Changes in Body Composition and Sleep

A one-year longitudinal study of 170 medical interns aged 18–25 at a Mexican public university hospital, assessed at baseline and after 12 months. The dataset, authored by Ricardo Salas-Flores and last updated in March 2026, likely contains anthropometric, body composition, physical activity, and sleep quality measurements. It was collected using bioimpedance analysis, the Global Physical Activity Questionnaire, and the Pittsburgh Sleep Quality Index.

Use Cases

• Modeling the relationship between sleep quality and body composition changes based on longitudinal measurements.
• Analyzing shifts in physical activity levels among medical trainees over a one-year period.
• Investigating gender differences in body fat mass and sleep quality profiles during internship.
• Training predictive models for health risk factors in high-stress professional environments.

Strengths

• Longitudinal design with 170 participants assessed at two time points over 12 months.
• Includes multiple validated measurement tools: bioimpedance analysis, GPAQ, and PSQI.
• Dataset is openly licensed under CC-BY-4.0 for reuse and redistribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single Mexican hospital, which may limit generalizability to other regions or healthcare systems.
