Differences in Self-Reported Stress Versus. Hair and Nail Cortisol Among Adolescent and Young Adult Males.

ABSTRACT

BACKGROUND: Chronic stress causes harmful physiologic responses that yield increased inflammation and subsequent health conditions. Stress is an important measure among minoritized populations who face social situations that predispose risk to developing mental health problems. Hair and fingernail cortisol have been studied as retrospective measures of chronic stress and to demonstrate biological response to social situations. OBJECTIVES: The objective of this study was to compare the Perceived Stress Scale (PSS) with hair and nail cortisol concentrations and assess the risk factors associated with stress levels among heterosexual and sexual and gender-minoritized adolescent males. METHODS: We recruited a cohort of adolescents who were assigned male sex at birth. Approximately half of our cohort consisted of sexual and gender-minoritized people, and half consisted of heterosexual cisgender males. Participants provided hair and nail samples and completed a survey that included demographic and hair hygiene questions, and the PSS. Hair and nail samples were processed in a lab and survey results were analyzed descriptively. RESULTS: Several samples were not provided or received, and some survey data was missing. Hair and nail cortisol values were significantly correlated. There was no significant relationship between the PSS and hair and nail cortisol values. No significant differences were found between the heterosexual and sexual minoritized groups. Black participants reported lower perceived stress scores compared to White participants. Participants whose gender was non-binary or genderqueer had higher hair cortisol values compared to those who identified as male. Older participants had higher hair cortisol values compared to younger participants. DISCUSSION: Previous researchers have similarly found no correlation between self-report stress scales and cortisol values, increased stress experience among non-binary or genderqueer individuals compared to cisgender individuals, and a positive correlation between aging and stress. Yet, our finding that Black participants reported lower stress levels than White participants is unexpected. Our study demonstrates a high correlation between hair and nail cortisol values, suggeting the potential to interchange these markers as needed.
