     The ratio of second to fourth digit length of the hand (2D:4D) has been shown to have a negative relationship with prenatal androgen levels and a positive relationship with BMI in human males, but not human females. These relationships may suggest a link between in utero androgen exposure and adult obesity. This project examines the relationship between 2D:4D and obesity in a captive population of vervet monkeys (Chlorocebus sabaeus) at Wake Forest School of Medicine. We analyzed anthropometric measures from 58 adults—52 females and 6 males—to determine the relationship between 2D:4D, chronic obesity (CO), and clinical markers of obesity: BMI, mass, and waist circumference. In males, we hypothesized higher 2D:4D when CO, and positive correlations between 2D:4D and clinical markers of obesity. In females, we expected no relationship between these factors and 2D:4D. As expected, we found no significant relationships in females, but found significantly lower 2D:4D in CO compared to non-obese males (t=3.4132, df=2.8751, p<0.05). Previous work suggests exposure to calorically restricted diets in utero is linked to CO in vervet males, but not females; perhaps this dietary effect is more important than presumed prenatal androgen exposure, but this relationship with 2D:4D is puzzling. Further research– and a larger sample size– will be necessary before we can accurately interpret these results.
