Childhood trauma and gender: Synergistic and additive effects on sleep in healthy young adults.

ABSTRACT:

Objectives

To examine whether gender moderates the effects of childhood trauma on subjective and objective sleep measures.

Design

Secondary data analysis, exploratory SETTINGS: Sleep research lab PARTICIPANTS: A total of 213 men and 278 women aged 18-30 completed subjective measures. A subsample of 172 participants without any psychiatric, medical, or sleep disorders completed objective polysomnography for 1 night at baseline, before sleep manipulation.

Measurements

Subjective measures: Childhood Trauma Questionnaire (CTQ), Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale. Objective measures: Standard polysomnography measures. Multiple regressions determined whether gender moderated CTQ score on any objective or subjective sleep measures. If gender was not a moderator, we examined additive effects of gender and CTQ score. Models were adjusted for race and age.

Results

Gender and CTQ score interactions were non-significant for both subjective (p > .675) and objective (p > .110) sleep. Women demonstrated better subjective sleep quality (Pittsburgh Sleep Quality Index, B = -0.264, p = .041) and more delta sleep than men (B = 3.032, p =.005). Greater CTQ score was associated with increased sleepiness (Epworth Sleepiness Scale, B = 0.029, p = .042), increased insomnia severity (Insomnia Severity Index, B = 0.027, p = .005), and lower REM density (B = -0.132, p = .045).

Conclusion

Our finding of greater delta sleep and better subjective overall sleep quality in women suggests that, among people without comorbidities, women may experience better sleep. Childhood trauma is associated with objective and subjective sleep measures, but this association is non-specific to gender. Clear links between childhood trauma and sleep are detectable in a sample of healthy sleepers with no comorbidities.

Project description:Human intestinal microbiota are influenced by various factors viz. diet, environment, age, gender, geographical, and socioeconomic situation, etc. among which diet has the most profound impact. However, studies investigating this impact have mostly included subjects from diverse geographic/socioeconomic backgrounds and hence the precise effects of dietary factors on gut microbiota composition remain largely confounded. Herein, with an aim to evaluate the association between dietary habits, specifically yogurt consumption, and the gut microbiota in healthy young adults sharing similar age, lifestyle routine, geographical setting, etc., we conducted a cross-sectional study wherein 293 collegiate freshmen answered a questionnaire about their frequency of yogurt consumption over the last 2 months and provided stool specimens for microbiota analysis. Fecal microbiota were analyzed by highly sensitive reverse-transcription-quantitative-PCR assays targeting bacterial 16S rRNA molecules. Fecal organic acids were measured by HPLC. Overall, the gut microbiota were predominated (97.1 ± 8.6%) by Clostridium coccoides group, Clostridium leptum subgroup, Bacteroides fragilis group, Bifidobacterium and Atopobium cluster. Interestingly, after adjusting the data for yogurt consumption, females were found to have higher total bacterial (P = 0.013) and Bifidobacterium (P = 0.046) count and fecal pH (P = 0.007) and lower fecal concentration of total organic acids (P = 0.030), succinic acid (P = 0.007) and formic acid (P = 0.046) as compared to males. Altogether, yogurt consumption showed positive linear association with Lactobacillus and Lactobacillus gasseri subgroup in both male and female subjects; however, several gender-specific disparities were also detected in this yogurt-microbiota association. Yogurt consumption demonstrated a negative association with L. sakei subgroup, Enterobacteriaceae and Staphylococcus in males but shared a positive association with L. casei subgroup and succinic acid in female subjects. The study manifests the association between yogurt consumption and gut microbiota in a healthy homogeneous cohort and show how this association can differ by host gender. The findings should be helpful for prospective studies investigating the diet-microbiome interaction in human health and disease.
