Sex differences in deterioration of sleep properties associated with aging: a 12-year longitudinal cohort study.

ABSTRACT:

Study objectives

The sleep patterns of humans are greatly influenced by age and sex and have various effects on overall health as they change continuously during the lifespan. We investigated age-dependent changes in sleep properties and their relation to sex in middle-aged individuals.

Methods

We analyzed data from 2,640 participants (mean age of 49.8 ± 6.8 years at baseline, 50.6% women) in the Korean Genome and Epidemiology Study, which assessed sleep habits using the Pittsburgh Sleep Quality Index and other clinical characteristics. We analyzed the sleep habit changes that occurred between baseline and a follow-up point (mean interval: 12.00 ± 0.16 years). Associations of age and sex with 9 sleep characteristics were evaluated.

Results

Age was associated with most of the sleep characteristics cross-sectionally and longitudinally (P < .05), except for the time in bed at baseline (P = .455) and change in sleep duration (P = .561). Compared with men, women had higher Pittsburgh Sleep Quality Index scores, shorter time in bed, shorter sleep duration, and longer latency at baseline (P ≤ .001). Longitudinal deterioration in Pittsburgh Sleep Quality Index score, habitual sleep efficiency, duration, and latency was more prominent in women (P < .001). The sex differences in these longitudinal sleep changes were mainly noticeable before age 60 years (P < .05). Worsening of Pittsburgh Sleep Quality Index scores, habitual sleep efficiency, and latency was most evident in perimenopausal women. Men presented with greater advancement of chronotype (P = .006), with the peak sex-related difference occurring when they were in their late 40s (P = .048).

Conclusions

Aging is associated with substantial deterioration in sleep quantity and quality as well as chronotype advancement, with the degree and timing of these changes differing by sex.

Project description:Importance:Longitudinal studies of delinquent youth have focused on criminal recidivism, not on psychosocial outcomes in adulthood. This omission is critical because after detention most youth return to the community, where they become the responsibility of pediatric health care professionals. Objective:To investigate 8 positive outcomes among delinquent youth 5 and 12 years after detention, focusing on sex and racial/ethnic differences. Design, Setting, and Participants:In the Northwestern Juvenile Project, a longitudinal US study of long-term outcomes of delinquent youth after detention, participants were interviewed in detention between November 20, 1995, and June 14, 1998, and reinterviewed up to 9 times during the 12-year study period, through May 12, 2011. Data analysis was conducted between November 18, 2013, and July 25, 2016. Exposures:Juvenile detention. Main Outcomes and Measures:Achievement of positive outcomes in 8 domains: educational attainment, residential independence, gainful activity, desistance from criminal activity, mental health, abstaining from substance abuse, interpersonal functioning, and parenting responsibility. Outcomes were assessed with widely used measures supplemented by correctional records. Results:The study included 1829 youth at baseline (1172 males and 657 females; mean [SD] age, 14.9 [1.4] years). At the end of the study, 1520 (83.1%) of the original sample remained (944 males and 576 females; mean [SD] age, 27.6 [1.4] years). Twelve years after detention, females were more likely than males to have positive outcomes for gainful activity (odds ratio [OR], 2.53; 95% CI, 1.86-3.44), desistance from criminal activity (OR, 5.89; 95% CI, 4.38-7.92), residential independence (OR, 3.41; 95% CI, 2.57-4.52), parenting responsibility (OR, 18.65; 95% CI, 12.29-28.30), and mental health (OR, 1.48; 95% CI, 1.13-1.92). Twelve years after detention, only 21.9% of males and 54.7% of females had achieved more than half of the outcomes. As youth aged, the number of positive outcomes increased only modestly (mean increase for males, 0.37; 95% CI, 0.13-0.62; for females, 0.29; 95% CI, 0.13-0.45). Among males, non-Hispanic white individuals were significantly more likely to achieve most positive outcomes compared with minorities, but less likely to abstain from substance abuse. For example, 12 years after detention, non-Hispanic white males had nearly 3 times the odds of educational attainment compared with African American (OR, 2.82; 95% CI, 1.77-4.50) and Hispanic males (OR, 2.91; 95% CI, 1.75-4.82), and 2 to 5 times the odds of gainful activity compared with African American (OR, 5.17; 95% CI, 3.16-8.45) and Hispanic males (OR, 2.58; 95% CI, 1.56-4.26). Latent class analysis shows that African American males fared the worst, with lives characterized by incarceration, criminal activity, and few positive outcomes. Conclusions and Relevance:Our findings highlight racial/ethnic disparities among youth in achieving positive outcomes after detention. To improve outcomes, pediatric health care professionals should recognize the importance of psychosocial health, partner with on-site psychosocial services in their practices, and facilitate access to services in the community.

Project description:BackgroundOlder women perform consistently poorer on physical performance tests compared to men. Risk groups for this "female disadvantage" in physical performance and it's development over successive birth cohorts are unknown. This is important information for preventive strategies aimed to enhance healthy aging in all older women. This study aims to longitudinal investigate whether there are risk groups for a more apparent female disadvantage and study its trend over successive birth cohorts.MethodsData of the Longitudinal Aging Study Amsterdam (LASA) were used. All participants were aged 55-65 years at baseline. Longitudinal data of two birth cohorts with baseline measurements in 1992/1993 (n = 966, 24 year follow-up) and 2002/2003 (n = 1002, 12 year follow-up) were included. Follow-up measurements were repeated every three/four years. Cross-sectional data of two additional cohorts were included to compare ethnic groups: a Dutch cohort (2012/2013, n = 1023) and a Migration cohort (2013/2014, n = 478) consisting of migrants with a Turkish/Moroccan ethnicity.ResultsMixed model analysis showed that women aged 55 years and older had a lower age- and height-adjusted gait speed (-0.03 m/s; -0.063-0.001), chair stand speed (-0.05 stand/s; -0.071--0.033), handgrip strength (-14,8 kg; -15.69--13.84) and balance (OR = 0.71; 0.547-0.916) compared to men. The sex difference in handgrip strength diminished with increasing age, but remained stable for gait speed, chair stand speed and balance. In general, results were consistent across different, educational levels and Turkish/Moroccan ethnic groups and birth cohorts.ConclusionsThere is a consistent "female disadvantage" in physical performance among older adults, which remains stable with increasing age (except for handgrip strength) and is consistent across different educational levels, ethnic groups and successive birth cohorts. So, no specific risk groups for the female disadvantage in physical performance were identified. Preventive strategies aimed to enhance healthy aging in older women are needed and should target all older women.
