چکیده

Background: digit ratio (2d:4d) is a marker of prenatal androgen exposure that has been associated with behavioral parameters. individuals with low 2d:4d are more aggressive and tend to engage in more physical activity.aim: we examined the relationship between 2d:4d and physical activity, sensation seeking and aggression in mature and immature boys.materials and methods: the study population consisted of mazandaran male students aged 9 to 17 years in 2019-2020. the sample was 218 healthy, cluster randomly selected boys (13.77±2.4 y/o) from three schools with no health issues. 2d:4d digit ratio, physical activity, aggression, sensation seeking were measured. pearson correlation analyzed variable associations. significance was considered at p≤0.05.results: low 2d:4d ratio was associated with higher physical activity (r≈-0.27), sensation seeking (r≈-0.3), and aggression (r≈-0.21), during childhood and adolescence (p<0.05). these relationships among right and left hand 2d:4d ratios with physical activity and sensation seeking remained consistent across maturity levels (p<0.05). only immature boys had a significant association between 2d:4d ratios and aggression (r≈-0.29, p<0.05). physical activity was positively associated with sensation seeking (r≈0.25, p<0.05), but not aggression in mature and immature boys.conclusion: prenatal testosterone organizes boys' physical activity and behavioral parameters, influencing the later development of sensation-seeking and aggression and greater participation in physical activity. the study has limitations such as a small sample size and a self-report method for assessing aggression. future research should focus on behavioral observation methods with larger sample sizes.
