The Effects of Familial Social Support Relationships on Identity Meaning in Older Adults: A Longitudinal Investigation

Nonlinear association between self-reported sleep duration and cognitive function among middle-aged and older adults in China: The moderating effect of informal care

BACKGROUND

Cognitive impairment is a major public health problem urgently to be solved. This study aims to examine the association between sleep duration and cognitive function and its two subdimensions: episodic memory and mental status, and to explore the moderating effects of informal care on these associations among middle-aged and older adults in China.

METHODS

Data was drawn from China Health and Retirement Longitudinal Study (CHARLS) 2011, 2013, 2015 and 2018 datasets. Sleep duration and informal care were self-reported. Cognitive function was measured using CHARLS Harmonized Cognitive Assessment Protocol. Effects of informal care on sleep duration-cognitive function were assessed using Generalized Estimating Equations models.

RESULTS

The relationships between sleep duration and cognitive function, episodic memory, and mental status were all found to follow an inverted U-shaped pattern. Spouse care weakened the adverse effects of extreme sleep duration on cognitive function while the children care amplified them. Further, we only observed the moderating effects of spouse and children care on the association between sleep duration and episodic memory, but not mental status.

CONCLUSIONS

The relationships between sleep duration and cognitive function, along with its different dimensions, are nonlinear in nature. The impacts of sleep duration on cognitive function and its dimensions are contingent upon the levels of informal care received and the sources of that care. We provide valuable insights into the complex interplay between sleep duration, informal care, and cognitive function.

Morphine exposure during adolescence induces enduring social changes dependent on adolescent stage of exposure, sex, and social test

Drug exposure during adolescence, when the 'reward' circuitry of the brain is developing, can permanently impact reward-related behavior. Epidemiological studies show that opioid treatment during adolescence, such as pain management for a dental procedure or surgery, increases the incidence of psychiatric illness including substance use disorders. Moreover, the opioid epidemic currently in the United States is affecting younger individuals raising the impetus to understand the pathogenesis of the negative effects of opioids. One reward-related behavior that develops during adolescence is social behavior. We previously demonstrated that social development occurs in rats during sex-specific adolescent periods: early to mid-adolescence in males (postnatal day (P)30-40) and pre-early adolescence in females (P20-30). We thus hypothesized that morphine exposure during the female critical period would result in adult sociability deficits in females, but not males, and morphine administered during the male critical period would result in adult sociability deficits in males, but not females. We found that morphine exposure during the female critical period primarily resulted in deficits in sociability in females, while morphine exposure during the male critical period primarily resulted in deficits in sociability primarily in males. However, depending on the test performed and the social parameter measured, social alterations could be found in both sexes that received morphine exposure at either adolescent stage. These data indicate that when drug exposure occurs during adolescence, and how the endpoint data are measured, will play a large role in determining the effects of drug exposures on social development.

Nearly Half of Women Have Experienced Intimate Partner Violence During Pregnancy in Northwest Ethiopia, 2021; The Role of Social Support and Decision-Making Power

Background

In developing countries, intimate partner violence is increasing alarmingly, though attention to this issue is rarely given. It has devastating effects on the general wellbeing of women, pregnancy outcomes, and the long-term health of children, and this needs to be addressed. Hence, this study was designed to assess intimate partner violence and associated factors in northwest Ethiopia.

Methods

A community-based cross-sectional study was conducted from July 1^st to August 30^th, 2021, among 858 postpartum women in Gondar city. A cluster sampling technique was employed to select the study participants. EPI DATA version 4.6 and SPSS 25 were used for data entry, cleaning and analysis, respectively. A bivariable and multivariable logistic regression model was fitted to identify factors associated with intimate partner violence. The level of significant association was declared using the adjusted odds ratio (AOR) with 95 % confidence interval (CI) and a p-value of ≤ 0.05.

Results

In this study, 48.6% of women indicated having experienced intimate partner violence during pregnancy (95% CI: 45.3, 51.7). The odds of intimate partner violence during pregnancy were significantly higher among women who were not able to read and write (AOR = 4.96; 95% CI: 2.15, 11.41), were private workers (AOR = 1.78; 95% CI: 1.05, 3.02), and had low decision-making power (AOR = 1.43; 95% CI: 1.06, 1.95), a poor social support (AOR = 1.99; 95% CI: 1.32, 3.02), and unsupported pregnancy by family (AOR = 2.32; 95% CI: 1.26, 4.24). Whereas a family size of ≥ 5 (AOR = 0.73; 95% CI: 0.54, 0.98) appeared to be a protective factor for intimate partner violence.

Conclusion

The magnitude of intimate partner violence was unacceptably high in the study area and connected to poor women's empowerment and social determinants of health. Thus, it is important to focus on interventions that improve women's access to social support and allow them to participate in all aspects of household decision-making through community-based structures and networks. It is also important to encourage women to improve their educational status and arrange risk-free employment opportunities.
