“…Although increased cortisol release in response to acute stressors can be adaptive, the prolonged activation of the HPA axis can lead to HPA dysregulation with downstream effects including the progression of various diseases, such as obesity, type 2 diabetes, and cardiovascular disease (McEwen & Wingfield, 2003). Studies indicate that Latinos have significantly flatter diurnal cortisol slopes than Caucasians due perhaps to greater stress exposure, including perceived discrimination (DeSantis et al, 2007).…”

Despite extensive research into the toll of persistent psychosocial stress on individual physiology and health, little is known about the effects of chronic biosocial stress for immigrant populations. In the present paper, the authors review challenges encountered when integrating minimally-invasive stress-related biomarkers (e.g., blood pressure, Epstein-Barr Virus [EBV] antibodies, C-reactive protein [CRP], and salivary cortisol), as well as anthropometric (e.g., height, weight, waist circumference) and metabolic measures (e.g., glucose, cholesterol), into research with Latino immigrant adults and families in Oregon, USA. Finally, the authors present lessons learned and discuss strategies to support the full engagement of Latino immigrants as participants in studies that rely on the collection of biological data as a central component of research into psychosocial stress and its effects.

“…Neste mesmo contexto, DeSantis et al 10 sugerem que, além dos fatores genéticos, uma maior exposição ao estresse pré-natal, baixo peso ao nascer, experiências adversas na infância, experiên-cias com racismo e discriminação podem ser fatores relevantes para o comportamento dos ritmos biológicos.…”

“…Os principais estudos, neste contexto, foram realizados com crianças e adolescentes norte-americanos com diferentes origens étnicas, normalmente, comparando origens africanas e europeias e têm verificado uma tendência de jovens com menor nível socioeconômico apresentarem pior qualidade de sono, maiores prevalências de insônia, menor duração do sono, maior frequência de despertares noturnos e apneia [4][5][6][7][8][9][10][11] .…”

resumo objetivo: Investigar a duração de sono na adolescência em diferentes níveis socioeconô-micos. método: Foram investigados 863 adolescentes de 10 a 19 anos em duas escolas de São Paulo, SP, Brasil. As coletas foram realizadas por meio de questionários para identificação de informações sobre os hábitos de sono e nível socioeconômico. resultados: A duração média de sono nos dias da semana foi de 8,83(1,87) horas e a prevalência de adolescentes com duração de sono de oito ou menos horas diárias foi de 39,0% nos dias com aula. Adolescentes da classe baixa apresentaram menor duração do sono (p = 0,043). Na análise ajustada, a idade, o nível socioeconômico e o hábito de tirar a sesta foram os principais fatores associados a poucas horas de sono. Os participantes de 18 a 19 anos apresentaram maior prevalência de poucas horas de sono em comparação aos de 10 a 11 anos (PR = 4,78; CI95%: 1,98-11,53), assim como os adolescentes da classe alta em comparação com a classe baixa (PR = 1,48; CI95%: 1,20-1,83). conclusão: Os resultados mostraram associações entre o nível socioeconômico e os hábitos de sono de adolescentes. (RP = 4.78;, as well as for upper class adolescents when compared to those with lower socioeconomic status. conclusion: Results showed the association between socioeconomic status and adolescents' sleep/wake habits.

“…Third, the majority of participants were Caucasian, which limits the generalizability of the current findings to other ethnoracial groups. Previous studies have established that both sleep (e.g., Stamatakis et al, 2007) and diurnal cortisol (e.g., DeSantis et al, 2007) differ across ethnoracial groups; future studies should evaluate the current model across diverse racial and ethnic samples. Fourth, the timing, duration, and nature of stressful experiences were not assessed, which may account for the lack of association between stressful life events with bedtime cortisol and diurnal slope.…”

SummaryRecent evidence suggests that poor sleep is a potential pathway underlying the association between stressful experiences and the diurnal cortisol profile. However, existing findings are largely limited to adults. The present study examines whether poor sleep (duration, quality) mediates the relation between stressful experiences and the diurnal cortisol profile in children and adolescents. Children and adolescents (N = 220, M age = 12.62) provided six saliva samples over two days to derive cortisol indices (bedtime, AUC AG , AUC TG , slope MAX ). Perceived stress, stressful life events, self-reported sleep duration, and sleep quality were measured. Using bootstrapping analyses, sleep quality mediated the relation between perceived stress and AUC TG (R2 = 0.10, F(7, 212) = 3.55, p = .001; 95% BCI[0.09, 1.15]), as well as the relation between stressful life events and AUC TG (R2 = 0.11, F(7, 212) = 3.69, p = .001; 95% BCI[0.40, 3.82]).These mediation models remained significant after adjusting for sleep duration, suggesting that poor sleep quality underlies the association between stressful experiences and the diurnal cortisol profile in children and adolescents. Longitudinal data combined with objectively-measured sleep is essential to further disentangle the complex association between sleep and stress. KeywordsSleep; Cortisol; Stressful life events; Perceived stress; Child; Adolescent Stress is known to alter cortisol secretion. Exposure to acute laboratory-induced stressors elicits transient increases in cortisol level (Dickerson and Kemeny, 2004). Naturally occurring stressful experiences, including perceived stress and stressful life events, have also been associated with a disrupted diurnal cortisol profile. Adults who report greater perceived stress (i.e., nonspecific, subjective appraised stress, Cohen et al., 1995) CIHR Author ManuscriptCIHR Author Manuscript CIHR Author Manuscript awakening response, total cortisol level, and flatter diurnal slopes (Miller et al., 2007;Pruessner et al., 1999;Schulz et al., 1998). Greater stressful life events (e.g., unemployment, divorce) are associated with higher morning and evening cortisol levels and flatter diurnal slopes (Miller et al., 2007). Similar findings have been established in both children and adolescents (hereafter referred to as "youth" for parsimony). Youth who report greater stressful life events (e.g., family conflict, academic stress) have a higher cortisol awakening response and elevated afternoon cortisol levels than their less stressed counterparts (Gustafsson et al., 2010;Wolf et al., 2008). While there is convincing evidence that stressful experiences disrupt the diurnal cortisol profile, the potential pathways underlying this association remain unclear.Sleep is one plausible pathway by which stressful experiences disrupt the diurnal cortisol profile. The sleep-wake cycle has a close, temporal association with diurnal cortisol secretion. Nocturnal sleep onset reliably exerts an inhibitory effect on cortisol secretion (Van Cauter et al.,...
