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

A longitudinal observational study of 170 medical interns (18–25 years) at a Mexican public university hospital, assessed at baseline and after 12 months. The dataset includes anthropometric and body composition parameters, physical activity levels, and sleep quality scores. It was authored by Ricardo Salas-Flores and last updated on 2026-03-18.

Use Cases

• Modeling changes in body fat mass and skeletal muscle mass based on longitudinal bioimpedance data.
• Analyzing the relationship between physical activity levels and sleep quality scores over time.
• Investigating gender differences in body composition changes and sleep profiles during medical internship.

Strengths

• Longitudinal design with measurements at baseline and 12-month follow-up for 170 participants.
• Includes multiple validated instruments: Global Physical Activity Questionnaire (GPAQ) and Pittsburgh Sleep Quality Index (PSQI).
• Body composition assessed using multifrequency bioimpedance analysis (InBody 270S).

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.
