Anogenital Distance and Perineal Measurements of the Pelvic Organ Prolapse POP Quantification System

The routine value of anogenital distance as an anthropometric measurement in newborns
Objective:
Anogenital distance (AGD) is a sexually dimorphic trait; AGD is an external marker of sexual differentiation at birth in animals.
Study Design:
The present study used a prospective, cross-sectional design. Data were collected from newborn infants that were delivered at hospital in Bucheon between March and September 2009. The mothers of the infants provided sociodemographic information and obstetric history. The relationships between AGD and other anthropometric measures (i.e., weight, height, and head circumference) were analyzed. Moreover adjusted AGD values were compared with obstetric characteristics, including number of deliveries, abortion history, preterm history, and duration of gestation.
Results:
Significant correlations were noted for all anthropometric measures in male and female newborns (p < 0.0001). The adjusted AGD values in males and females were also significantly associated with the duration of gestation (p = 0.0008 and p = 0.0148, respectively). Moreover, the adjusted AGD in female newborns, but not in males, was significantly associated with maternal abortion history (p = 0.0242).
Conclusion:
The AGD is a valuable anthropometric marker in term infants.
