Sex differences in domain-specific depressogenic cognitive responses to negative and positive life events

Sex differences in the relationship between morningness-eveningness components, mood and well-being among Bangladeshi university students

On the Morningness/Eveningness (M/E) continuum, eveningness has been related to mood disorder and poor well-being. M/E differs between men and women throughout their lifespan. However, there is a lack of information on sex differences in the relationship between M/E, mood, and well-being. This study aimed to test sex differences in the M/E, mood, and well-being relationship with consideration of two components of M/E, morning affect, and morning preference. A sample of 981 Bangladeshi university students (607 men) aged 18 to 27 (M = 21.95) completed Bangla versions of the Composite Scale of Morningness (CSM), BRUnel Mood Scale (BRUMS), and Positive Mental Health scale (PMH-scale) through an online survey. Multiple regression analyses were used to test the relationship of M/E components with mood and well-being. The results showed that the relationship between M/E, mood, and well-being was greater in women than in men. A lower score on both M/E components was related to higher negative moods (anger, confusion, depression, fatigue, and tension) and poor well-being. In regression analysis, only morning affect was found to be significant, which means that morning affect mainly contributes to the relation between M/E, mood, and well-being. Finally, sex by morning affect interaction indicated that the relation was higher for women. Therefore, higher eveningness could be more hazardous for women than men. Greater insight into the independent contribution of morning affect may facilitate understanding of the chronotype effects on psychological outcomes in men and women.

Sex differences in the association between chronotype and risk of depression

Information on sex differences in the association between chronotype and depression is scarce. We aimed to investigate these differences using data from the Korea National Health and Nutrition Examination Survey in 2016. Chronotypes were categorised based on mid-sleep time on free days corrected by sleep debt accumulated on workdays (MSFsc): early type, < mean MSFsc - 1 standard deviation (SD); intermediate type, between mean MSFsc - 1 SD and MSFsc + 1 SD; and late type, > mean MSFsc + 1 SD. A Patient Health Questionnaire-9 score of ≥ 10 indicated depression. Among 5550 non-shift working adults aged 19-80 years, the prevalence rates of depression in the early, intermediate, and late chronotype groups were 7.4%, 4.5%, and 9.3%, respectively. Women with late chronotype (odds ratio [OR] = 2.9, 95% confidence interval [CI] = 1.8-4.7) showed a higher risk of depression than women with intermediate chronotype after adjusting for covariates. Women with early chronotype did not show a significant difference in depression risk (OR = 1.3, 95% CI = 0.9-2.0). In conclusion, late chronotype is associated with an increased risk of depression in women but not in men. Early chronotype is not associated with depression in women or men.

Life-stress and reactivity by gender in a longitudinal birth cohort at 30 and 35 years

PURPOSE

Previous literature has shown gender differences in reactivity to stressful life events. However, it is unclear whether gender differences in stress reactivity are consistent across a series of life event domains among longitudinal adult sample populations.

METHODS

Data were gathered from the Christchurch Health and Development Study (CHDS). The CHDS is a longitudinal birth cohort of 1265 children born in 1977 in Christchurch, New Zealand. Cohort members were questioned on their experience of, and distress from, a series of life event domains (interpersonal problems; victimization; illness/death; pregnancy/parenthood; employment/finance problems) spanning two age-periods 25-30 years (data collected in 2007) and 30-35 years (data collected in 2012). The data were pooled across observations and analyzed using population-averaged repeated-measures regression methods.

RESULTS

Overall, men and women reported experiencing similar numbers of life events for each domain. However, men reported more victimization and more employment/financial problems; women reported more illness/death events. Women reported experiencing more distress per life event for the domains of interpersonal problems, illness/death and pregnancy/parenthood. Men and women reported similar distress per life event for the victimization and employment/finance domains. The results were robust to control for: child and adolescent factors (childhood abuse exposure; adolescent personality; mental health) and adult factors (mental health; self-esteem).

CONCLUSION

These findings are consistent with a growing body of evidence indicating that some life events including interpersonal problems, illness/death and pregnancy/parenthood may be intrinsically more distressing for women. Detection of life event distress is important to aid in the prevention of mental/physical health problems.

Gender-Related Factors for Depressive Symptoms in Turkish Adolescents

PROBLEM

Currently more adolescents suffer from mental health problems than compared to the past.

PURPOSE

This study was designed to extend the knowledge of depressive symptoms in adolescence and to determine the gender-related factors associated with it.

METHODS

The study sample consisted of (N = 487) adolescents. The Children's Depression Inventory (CDI), Multidimensional Scale of Perceived Social Support (MSPSS), Strengths and Difficulties Questionnaire (SDQ-S), and UCLA loneliness scale (UCLA-LS) were completed by the participants.

FINDINGS

Among the study population, 26.6% (n = 130) scored ≥ 19 on the CDI, which was the cut-off point. UCLA-LS, hyperactivity and conduct problems, and peer problems subscale scores of SDQ-S were found significantly higher in males (p < .05). Emotional symptoms, pro-social behavior subscale scores of SDQ-S, and a family member, a friend subscale scores of MSPSS were found significantly higher in females (p < .05). For males, loneliness and hyperactivity and conduct problems, while for females, emotional symptoms and loneliness (p < .05) were predictive variables. Pro-social behavior and perceived family member support were protective variables for females scoring high enough to be diagnosed with depression (p < .05).

CONCLUSION

We suggest further studies to confirm these results as well as establishing strategies for better detection of depressive symptoms when working on adolescents.
