Latinos have been disproportionately affected by the COVID-19 pandemic in the US. Little is known about the lasting effects on mental health, particularly among mothers of young children, who historically report high levels of depression and anxiety. We examined if anxiety and depression symptoms worsened for mothers of Mexican descent across the p...

Perinatal depression has been associated with lower oxytocin (OT) levels. However, few studies have explored this topic in relation to Latinas who are at high risk of perinatal depression. The objective of this study was to explore these associations in Latinas. A total of 108 Latinas in the third trimester of pregnancy participated in the study. D...

Objectives: Exposure to psychosocial stressors is associated with increases in adverse mental health outcomes and inflammatory markers. Limited research has investigated if acculturative stress, related to cultural adaptation in Latinos, one of the fastest growing minority groups in the United States, follows a similar pattern. This study hypothes...

Over half of pregnant women report anxiety symptoms and these symptoms may be precipitated by stressful experiences. Anxiety rates may be higher in Mexican-American women who experience sociocultural stressors, such as acculturation, acculturative stress and discrimination. However, the role of such stressors on the trajectory of anxiety symptoms a...

Objective: Fetal cortisol may be reflected in hair collected shortly after birth. The objective of this study was to determine the range of human fetal hair cortisol concentrations (HCC) in live-born neonates using an approach for processing small quantities of hair. Materials and methods: Hair was cut on the day of birth from neonates and their...

Objective: Greater acculturation is associated with adverse perinatal outcomes in Mexican-American women, but the mechanisms by which acculturation influences perinatal outcomes are unclear. Pregnant acculturated Mexican-American women are more likely to engage in unhealthy prenatal behaviors relative to those less acculturated, including poor sle...

Mexican-American women exhibit high rates of prenatal maternal depressive symptoms relative to the general population. Though pregnant acculturated Mexican-American women experience cultural stressors such as acculturation, acculturative stress and discrimination that may contribute to elevated depressive symptoms, the contribution of these socio-c...

As more pregnant Mexican-Americans integrate into US culture, they are vulnerable to a unique stressor termed acculturation. Acculturation and the stresses associated with this process have detrimental effects on maternal health. Social support and Mexican cultural values can buffer against the effects of acculturation and may alleviate prenatal me...

As the Mexican population grows in the US, Mexican-Americans face the acculturative pressure of accommodating to the dominant American culture while maintaining their Mexican culture. This process of acculturative stress is associated with increased symptoms of depression and anxiety. Mood disorders are particularly prevalent among Mexican-American...

Understanding parental psychopathology interaction is important in preventing negative family outcomes. This study investigated the effect of paternal psychiatric history on maternal depressive symptom trajectory from birth to 12 months postpartum. Maternal Edinburgh Postpartum Depression screens were collected at 1, 6 and 12 months and fathers' ps...

Prenatal maternal anxiety has detrimental effects on the offspring's neurocognitive development, including impaired attentional function. Antidepressants are commonly used during pregnancy, yet their impact on offspring attention and their interaction with maternal anxiety has not been assessed. The authors used P50 auditory sensory gating, a putat...

There is mounting evidence that stress during pregnancy can have detrimental effects on gestation and birth. Existing studies indicate that prenatal stress may increase levels of circulating inflammatory markers that are associated with prematurity and pregnancy complications, suggesting that stress-related changes in the cytokine milieu may increa...

This study investigated the effects of acculturation on cortisol, a biological correlate of maternal psychological distress, and perinatal infant outcomes, specifically gestational age at birth and birth weight. Fifty-five pregnant women of Mexican descent were recruited from a community hospital, and their saliva samples were collected at home for...

Maternal stress during pregnancy is associated with negative maternal/child outcomes. One potential biomarker of the maternal stress response is cortisol, a product of activity of the hypothalamic-pituitary-adrenal axis. This study evaluated cortisol levels in hair throughout pregnancy as a marker of total cortisol release. Cortisol levels in hair...

Maternal defense (also known as maternal aggression) is impaired by corticotropin-releasing factor-(CRF) related peptides, but where these peptides inhibit defense is unknown. Lateral septum (LS) gates reactivity to stressors, contains receptors to CRF-related peptides, and during lactation shows a decreased response to CRF, suggesting LS is a key...

Neurotensin (NT) is a versatile neuropeptide involved in analgesia, hypothermia, and schizophrenia. Although NT is released from and acts upon brain regions involved in social behaviors, it has not been linked to a social behavior. We previously selected mice for high maternal aggression (maternal defense), an important social behavior that protect...

Mice deficient in corticotropin-releasing factor receptor 2 (CRF2) (C57BL/6J:129Sv background) exhibit impaired maternal defense (protection of offspring) and are more reactive to stressors than wild-type mice. To further understand CRF2's role in maternal behavior, we crossed the knockout mice with a line bred for high maternal defense that also h...

Child neglect is the most common form of child maltreatment, yet the biological basis of maternal neglect is poorly understood and a rodent model is lacking. The current study characterizes a population of mice (MaD1) which naturally exhibit maternal neglect (little or no care of offspring) at an average rate of 17% per generation. We identified a...

Increases in neuronal activity of hypocretin (HCRT), a peptide involved in arousal, and in HCRT-1 receptor mRNA expression have recently been identified in association with lactation. HCRT is released within brain regions regulating maternal behaviour and it is possible that increased HCRT neurotransmission during lactation supports maternal care....

Lactating female mice fiercely defend offspring while exhibiting decreased fear and anxiety. Recent work (J. S. Lonstein & S. C. Gammie, 2002) found that intracerebroventricular (icv) injections of corticotropin releasing factor (CRF), a putative anxiogenic peptide, inhibit maternal defense behavior. This study examines effects of CRF-related pepti...

Maternal aggression is a form of aggression towards intruders by lactating females that is critical for defense of offspring. During lactation, fear and anxiety are reduced, the CNS is less responsive to the anxiogenic neuropeptide, corticotropin-releasing factor (CRF), and central injections of CRF inhibit maternal aggression. Together, these prev...
