Infant Sex, Weight Gain, and Iron Deficiency Risk at 6 Months

355 healthy term infants from a Chinese hospital cohort show male sex is associated with a 2.13 times higher odds of iron deficiency at 6 months. The study by Dongmei Ge, with data from 2023-2024, indicates rapid weight gain mediates 40% of this sex-based risk. Findings suggest a need for sex-specific nutritional guidelines.

Use Cases

• Train models to predict iron deficiency risk based on infant sex, weight gain, and feeding type.
• Conduct mediation analysis to understand pathways linking biological sex to nutritional outcomes.
• Benchmark growth trajectories against iron status for clinical risk stratification.

Strengths

• Includes 355 infant records with a 55.5% male cohort composition.
• Provides specific statistical results, including an adjusted odds ratio of 2.13 for male sex and ID risk.
• Data covers a defined time range from January 2023 to June 2024.

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 hospital in China, which may limit generalizability.
