Anthropometric measures do not explain the 2D:4D ratio sexual dimorphism in 7-year-old children.

ABSTRACT:

Objectives

Digit ratio (2D:4D) might reflect prenatal testosterone exposure and has been used as a putative marker for androgen related outcomes. However, such associations might be inflicted by confounders. Application of 2D:4D in epidemiological research motivate identification of biological background determinants. We examined sex, anthropometric measures, and maternal factors as determinants of 2D:4D in Swedish 7-year-old children.

Methods

The study was embedded in the Swedish Environmental, Longitudinal, Mother and Child, Asthma and Allergy (SELMA) pregnancy cohort. A total of 870 pre-pubertal children, median 7.5 years of age, were studied. A single assessor performed digit measurements from scanned photocopies using computer software.
