The relationships between maternal psychosocial stress during pregnancy and asymmetry in dermal ridge count, gestation length, birth weight percentile and survival were examined in 68 pigtailed macaque offspring. Twenty-five pregnant females were stressed daily by capture from 30 through 130 days postconception; 43 control unstressed females were housed under conditions of minimal disturbance. The difference between total intercore dermal ridge counts between right and left hands of the offspring was used as a measure of the perturbed development that theoretically occurs in the presence of a prenatal stressor. Dermatoglyphic asymmetry was significantly higher in the stressed offspring than in the unstressed group (mean asymmetry = 7.3 +/- 2.8 and 5.4 +/- 2.5, respectively; t = 2.85, p less than 0.01). Although maternal stress alone was not related to differential gestation length, birth weight, or survival, high asymmetry (8-13 residual dermal ridges) was significantly associated with increased perinatal mortality.
在68只豚尾猕猴后代中，研究了孕期母体心理社会压力与皮嵴计数不对称、妊娠期长度、出生体重百分位数及存活率之间的关系。25只怀孕雌性猕猴在受孕后30天至130天期间每天被捕捉从而承受压力；43只未受压力的对照雌性猕猴饲养在干扰最小的环境中。后代左右双手间总指嵴纹数的差异被用作衡量在产前应激源存在时理论上发生的发育扰动的指标。应激后代的皮纹不对称性显著高于未应激组（平均不对称性分别为7.3±2.8和5.4±2.5；t = 2.85，p<0.01）。虽然单独的母体压力与妊娠期长短、出生体重或存活率差异无关，但高不对称性（8 - 13条残余皮嵴）与围产期死亡率增加显著相关。
