Table 1_Medical interns and health challenges: insights into physical inactivity, sleep di

170 medical interns at a Mexican public university hospital were assessed for changes in body composition, physical activity, and sleep quality over a 12-month period. The study, authored by Ricardo Salas-Flores and last updated in March 2026, reports a mean BMI increase from 25.47 to 26.22 kg/m² and a deterioration in overall sleep quality among participants.

Use Cases

• Modeling the relationship between physical activity levels and body composition changes based on bioimpedance measurements.
• Analyzing longitudinal trends in sleep quality deterioration among medical trainees.
• Investigating gender differences in body fat mass changes and sleep quality profiles during internship.
• Evaluating the effectiveness of wellness interventions by establishing baseline health metrics for medical interns.

Strengths

• Longitudinal design with baseline and 12-month follow-up assessments for all 170 participants.
• Body composition measured using multifrequency bioimpedance analysis (InBody 270S).
• Standardized instruments used: Global Physical Activity Questionnaire (GPAQ) and Pittsburgh Sleep Quality Index (PSQI).
• Statistical analysis includes effect sizes (Cohen's d and Cramér's V).

Limitations

• Dataset is very small at 44.7 KB, indicating limited scope and sample size.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a single cohort from one Mexican hospital, which may limit generalizability.
