Physical Activity and Immune Cell Associations in Young Healthy Women

A study of 141 healthy women aged 20–36 monitored over two menstrual cycles using Fitbit accelerometers. The dataset contains associations between physical activity metrics and immune cell parameters, including NK cell subpopulations and cytotoxic T lymphocytes, analyzed via flow cytometry. The data was authored by Anna Tubek-Krokosz and last updated on 2026-05-29.

Use Cases

• Modeling associations between daily step count and CD56brightCD16+ NK cell proportions based on regression results.
• Analyzing the relationship between very active minutes and natural NK cell cytotoxicity based on the described beta coefficients.
• Investigating the effect of moderate physical activity on immune cell subpopulations in a young, female cohort as described in the study background.

Strengths

• Dataset is based on a study of 141 participants, providing a specific sample size.
• Includes specific statistical associations (e.g., β=0.22, p=0.016 for steps and CD56brightCD16+ NK cells).
• Physical activity was objectively monitored using Fitbit accelerometers over two menstrual cycles.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to a specific demographic of 141 healthy women aged 20–36.
