Association of maternal and paternal psychosocial stress and infant hair cortisol among Arab American immigrants: A pilot study.

Acculturative stress is unique among immigrants and refers to the stress associated with maintaining cultural values and traditions in the host country. Immigrant parents confront psychosocial variables such as acculturative stress, anxiety, and depression that might result in intergenerational negative consequences on their infants. Measurement of hair cortisol concentration (HCC), an outcome of neuroendocrine dysregulation, is one relatively noninvasive approach to gauge stress in infants. No published studies have evaluated associations among parents' psychosocial variables and infants' HCC among immigrant families. Therefore, the purpose of this study was to: (1) examine the relationship between maternal and paternal psychosocial stress variables; and (2) examine the association between psychosocial variables of both parents (acculturative stress, anxiety, and depression) and infants' HCC among immigrant Arab American families. A sample of 31 immigrant Arab American triads (mother-father-infant) was recruited. During one home visit, each parent completed the study questionnaires separately when the baby was 6-24 months old and a hair sample was collected from the infant for HCC. Parents reported significant symptoms of anxiety (33% mothers; 45% fathers) and depression (33% mothers; 35.5% fathers). Paternal acculturative stress, anxiety, and depressive symptoms were significantly correlated to infants' HCC. Acculturative stress, anxiety, and depressive symptoms were significantly correlated between mother-father dyads. Future research should continue to focus on immigrant families and include both parents to better understand and improve infant health.
