Cortisol Reactivity as a Predictor of Weight Gain Among Prenatally Drug-Exposed Girls
Cortisol reactivity and weight gain among adolescents who vary in prenatal drug exposure. Author: Armstrong B, et al. (2018), Pediatr Obes. OBJECTIVE: Low inhibitory control is linked with weight gain among youth. Inhibitory problems are associated with disruption to the hypothalamic-pituitary-adrenal axis cortisol response. Increased cortisol predicts appetite and weight gain (though may be gender specific). This study hypothesized that cortisol reactivity explains […]
Salivary Cotinine Suggests Infants from Low-Income Families have a Higher Smoke Exposure Risk
Magnitude and Chronicity of Environmental Smoke Exposure Across Infancy and Early Childhood in a Sample of Low-Income Children. Author: Gatzke-Kopp LM, et al. (2018), Nicotine Tob Res. INTRODUCTION: Infants and young children may be at an increased risk for second- and thirdhand exposure to tobacco smoke because of increased respiration rate and exposure to surface residue. […]
Salivary Uric Acid May Be Associated with Cardiovascular Health Risks in African Americans
Salivary uric acid: Associations with resting and reactive blood pressure response to social evaluative stress in healthy African Americans. Author: Woerner J, et al. (2018), Psychoneuroendocrinology. ABSTRACT: High levels of uric acid are associated with greater risk of stress-related cardiovascular illnesses that occur disproportionately among African Americans. Whether hyperuricemia affects biological response to acute stress remains largely […]

Salivary Hormonal Responses Related to Menstrual Cycle
Menstrual cycle phase predicts women’s hormonal responses to sexual stimuli. Author: Shirazi TN, et al. (2018), Horm Behav. ABSTRACT: A robust body of research has demonstrated shifts in women’s sexual desire and arousal across the menstrual cycle, with heightened desire and arousal coincident with heightened probability of conception (POC), and it is likely that ovarian hormones modulate […]
Salivary Estradiol Corresponds to Genetic Influences for Binge Eating in Pubescent Girls
Estrogen moderates genetic influences on binge eating during puberty: Disruption of normative processes? Author: Klump KL, et al. (2018) , J Abnorm Psychol. ABSTRACT: Puberty is a critical period for changes in genetic effects for binge eating in girls. Previous twin studies show increases in genetic influences on binge eating from prepuberty (∼0%) to midpuberty and […]
Salivary Cortisol and Alpha-Amylase Connection in Mother-Infant Interactions
Ecologically salient stressors and supports and the coordination of cortisol and salivary alpha-amylase in mothers and infants. Author: Hibel LC, et al. (2018), Physiology and Behavior. ABSTRACT: This study examines the integration of the two main branches of the stress response system: the autonomic nervous system (via salivary alpha-amylase, sAA) and the hypothalamic-pituitary-adrenal axis (via cortisol). Mothers (n = 117) were […]
Salivary Stress Biomarkers as Tools for Determining Stress Adaptability and Resilience
Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. Authors: Hellewell SC & Cernak I (2018), J Trauma Stress. ABSTRACT: Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas others […]

Salivary Secretory Immunoglobulin A (SIgA) Associations with Social Network Structures
Associations between Secretory Immunoglobulin A and Social Network Structure. Author: Kornienko O, et al. (2018). PURPOSE: This study investigates the social determinants of health by examining how mucosal immunity is associated with the patterning of social connections in a network. Studies have suggested that social networks have biological underpinnings, but investigations at the scale of […]
