A Bronze Age Site on the Northern Coast of West Java

This study describes an early site on the northern coast of West Java, affected by the Austronesian culture—Subanglarang near Binong in the Subang Regency. Geologically, during the 2000–1000 BP interval, it was part of the coastline of the northern coast of West Java, situated more than 5 m asl. During the 2013 surveys and excavations in 2016 and 2018, five burials were revealed. On the basis of the fragments of red-slipped pottery, pickaxes, beads of various shape and size, and metal weapons, the site is dated to the Bronze Age. Artifacts similar to those of early Austronesians were discovered. The analysis of various beads from Subanglarang attests to trade relations with other areas. Further excavations on the northern coast of West Java will hopefully shed more light on the life of the Bronze Age people of that area.

Design of randomized controlled trials to estimate cancer-mortality reductions from multicancer detection screening.

Determining whether screening with multicancer detection (MCD) tests saves lives requires randomized controlled trials (RCTs). To inform RCT design, we estimated cancer-mortality outcomes from hypothetical MCD RCTs. We used the Hu-Zelen model, previously used to plan the NLST, to estimate mortality reductions, sample-size, and power for 9 cancers for different RCT design parameters and MCD test parameters. Our base-case RCT with 5 yearly screens and 100,000 people ages 60-74 in each arm, who also undergo standard-of-care screens, has 87-89% power to detect an 9-10% mortality reduction (NNS = 578-724) over 7-9 years. The majority of prevented deaths were from lung-cancers (base-case (64-66%) and all sensitivity analyses), 8-10% from colorectal-cancer, and 26% from the other 7-cancers, mostly from stomach/ovary/esophagus (due to excellent stage-1 survival) and less from liver/pancreas (poor stage-1 survival) or head/neck-cancer/lymphoma (excellent stage-4 survival). There was limited power for mortality reductions at most individual cancer sites. Base-case findings were sensitive to test sensitivity, stage-shifts, and mean sojourn times in the preclinical state (especially for lung-cancer), but 90% power could be recovered by recruiting a substantially higher risk population. Large-scale MCD RCTs would have 89% power to detect a ∼10% cancer-mortality reduction over a relatively short 7-9 year timeframe from trial entry. The estimated NNS for MCD RCTs compares favorably to mammographic screening. Most prevented cancer-deaths in a well-powered MCD RCT would likely be from lung-cancer. Non-lung/CRC cancer sites could be a meaningful proportion of prevented cancer-deaths but power is insufficient to isolate non-lung-cancer mortality reductions.

Association of heat and cold waves with cause-specific mortality in Iran: a systematic review and meta-analysis

Despite the frequent occurrence of heat waves in the Middle East, there is a lack of evidence regarding the overall estimates for the effect of heat waves on mortality in this region. This study aimed to review the effect of exposure to heat and cold waves and daily cause-specific mortality. Four electronic databases were searched. The titles, abstracts, and full-texts of the articles were carefully reviewed by two researchers. Once eligible studies were identified, the required data were extracted. Separate meta-analyses were conducted based on gender, age group, and health endpoint combinations. According to the meta-analysis, heat waves had a statistically significant effect on all-cause mortality with an RR of 1.23 (CI 95%: 1.08, 1.39). Cardiovascular mortality significantly increased in heat waves with an RR of 1.08 (CI 95%: 1.05, 1.10). However, the increase in respiratory mortality was not statistically significant. Compared to young people (age < 65 years old) and women, elderly and men were more vulnerable to heat waves with RRs of 1.31 (95% CI: 1.05, 1.57) and 1.33 (95% CI: 1.08, 1.58), respectively. This study can be beneficial in developing response or adaptation plans for heat waves. Future studies should focus on other specific health endpoints like ischemic heart disease, chronic obstructive pulmonary diseases, etc., and other outcomes such as hospitalization and emergency visits.

Nightmares in the elderly: Associations with self-reported executive functions

Study objectivesTo describe nightmare phenomenology among community dwelling elderly and to test the hypothesis that reduction in cognitive control is associated with nightmare-related phenomenology including nightmare frequency and severity, greater emotional reactivity, imagery immersion, and dream enactment behaviors (DEBs). MethodsStudy 1: Survey with multiple regression and ANOVAs on N = 56 people with frequent nightmares plus N = 62 age- and gender-matched controls to quantify the strength of the association between cognitive control variables and nightmare phenomenology. Study 2: Computational simulation of nightmare phenomenology in relation to cognitive control to simulate the empirical findings and to assess the underlying causal theory through computationally supported causal inference. ResultsStudy 1: Regressions demonstrated a strong association between reduction in cognitive control and more extreme nightmare phenomenology, including severity, frequency, daytime effects, and DEBs. Study 2: The computational simulation of nightmare phenomenology in relation to cognitive control is validated relative to regressions from study 1 and offers computational support for the causal theory explaining the associations in study 1. ConclusionsIn aging people, decline in executive cognitive functions, cognitive control, and inhibitory processes reduce cognitive control over emotions, thus contributing to unusual nightmare activity, including more extreme nightmare phenomenology such as more severe nightmares, greater emotional reactivity, deeper imagery immersion, and DEBs.

Sound quality characteristics of reciprocating hermetic refrigeration compressors

In recent years, sound quality (SQ) has become an increasingly important factor in the home appliance industry, enhancing the customer experience and comfort. Manufacturers that prioritize SQ in their designs can gain a competitive advantage in the market and increase customer satisfaction. The compressor is one of the main sources of noise in a refrigerator. While manufacturers typically provide refrigerator sound quality and noise labels, research that specifically evaluates the compressor sound quality metrics at a component level is not common. Therefore, this study aims to isolate the compressor from the refrigerator to investigate SQ metrics for hermetic refrigeration compressors. To achieve this, compressors with different capacities are operated and recorded at different working speeds for different thermal conditions. Objective parameters are calculated and tested using time domain signals and analyzed with spectral analysis methods. In addition to the objective parameters, subjective results are obtained through jury tests consisting of 75 people of different genders and age ranges. By considering objective parameters of sound quality as input and sound quality evaluation values as output, a regression model is established. It is found that Loudness, Sharpness, and Degree of Modulation play an important role in compressor sound quality evaluations consider.

Governing aging people in a rural commune during the Covid-19 pandemic: A case study

Based on the case study of a rural commune, this article analyzes how the challenges of ensuring the inclusion, participation and protection of older residents were addressed by local political actors and partly redefined following the outbreak of the Covid-19 pandemic. It appears that the mutual knowledge between the inhabitants, the proximity of public and private players and the relational and organizational capital of the people in charge are the main levers that can be used to govern older inhabitants. The research shed light on the gap between local actors’ perceptions of older residents, of their expectations and needs and the way older inhabitants themselves define their own place within the town.

Implicit motor imagery: examining motor vs. visual strategies in laterality judgments among older adults

Cognitive states like motor imagery (MI; simulating actions without overtly executing them) share a close correspondence with action execution, and hence, activate the motor system in a similar way. However, as people age, reduction in specific cognitive abilities like motor action simulation and action planning/prediction are commonly experienced. The present study examined the effect of visual–spatial processing for both typical and challenging upper-limb movements using the Hand Laterality Judgment Task (HLJT), in which participants were asked to judge whether the depicted hand is a left or right hand. Several main findings emerged: (1) Compared to younger adults, older adults exhibited slower responses and greater error rates in both Experiment 1 and 2. This suggests that visual–spatial transformations undergo alterations with age; (2) Older adults displayed higher error rates with realistic hands at both back and palm viewpoints of the hands compared to younger adults. However, this pattern did not hold for response times; (3) Participants responded faster to medial hand orientations (i.e., closer to the midline of the body) compared to lateral hand orientations (i.e., farther from the midline of the body) for palm-views in both Experiment 1 and Experiment 2. Given that we observed better performance on medial orientations compared to lateral orientations, this suggests that participants follow the same motor rules and biomechanical constraints of the represented movement. Novel information is provided about differences in individuals’ use of strategies (visual vs. motor imagery) to solve the HLJT for both mannequin and real hands.

State of Geographic Access to Cancer Treatment Trials in the United States: Are Studies Located Where Patients Live?

In this study, we describe the geographic distribution of US cancer treatment trials to identify disparities and opportunities for targeted improvements in access to research for people with cancer. US-based phase I-III cancer treatment trials registered on ClinicalTrials.gov were tabulated for the years they were open to enrollment (2017-2022), overall and by county, and supplemented with data from the US Census Bureau, National Cancer Institute, Centers for Disease Control and Prevention, and US Department of Agriculture. We evaluated geographic differences in trial availability. We assessed 5-year trends in trials per capita and mapped 1-hour drive time areas around sites. A total of 6,710 trials were open to enrollment in 2022 across 1,836 sites. Trials increased by 4%, whereas sites decreased by 3% annually per capita from 2017. Seventy percent of US counties had no reported active trials in 2022 (2,211/3,143), representing 19% of people age ≥55 years. Eighty-six percent of nonmetropolitan counties had no trials versus 44% of metropolitan counties. Trial availability varied by county-level cancer mortality and social vulnerability (an index derived from demographic and socioeconomic data from the US Census). Eighteen percent of counties without trials had oncologist care sites (n = 618). Notably, 26% of people age ≥55 years lived beyond an hour drive of a site with ≥100 trials. Most US counties have limited to no trial offerings, a disparity magnified in counties that are nonmetropolitan, with high social vulnerability, and with high cancer mortality. Effort to facilitate diverse site participation is needed to promote equitable access to trials and to ensure patients participating in trials match the characteristics of patients who will receive interventions once approved. Counties with oncology care sites but no trials provide potential expansion areas.

Health Status of People Who Are and Are Not Experiencing Homelessness: Opportunities for Improvement

This study assessed the physical and psychological health parameters of adults experiencing homelessness to inform the development and delivery of health services by comparing with a housed population in the same South Australian city. Adults experiencing homelessness, known to existing support services, were invited to participate in a comprehensive assessment of their physical and mental health using questionnaires and objective assessments. Descriptive analyses using the percentage of participants failing to attain recommended published thresholds and accumulated health deficits for 16 health assessments were compared for the young group of people experiencing homelessness (18–40 years), the middle aged and older people experiencing homelessness (40–75 years), and a housed population of the middle aged and older people (40–75 years). Those experiencing homelessness had multiple and potentially inter-related health deficits compared with a population of people not experiencing homelessness in the same city. They were significantly less likely to meet healthy population norms for clinical frailty (p &lt; 0.001), psychological distress (p &lt; 0.001), grip strength (p &lt; 0.001), lung function (p &lt; 0.001), sleep quality (p &lt; 0.001), and pelvic floor bother (p = 0.002). Significantly more accumulated health deficits were found for people experiencing homelessness when compared with the same ages for those who were not (mean 6.5 (SD 2.4) compared with 5.0 (SD 2.1)). This considerably increased for people experiencing homelessness aged less than 40 years (mean 8.7 (1.7)). Priorities for health service provision for people of different ages experiencing homelessness, when compared with housed community dwellers, have been described. The provision of targeted health assessments and service provision that specifically address healthcare needs among people experiencing homelessness are likely to have the biggest impacts across multiple health domains.

Trusted networks: a study of communication flow and access to abortion information in Argentina.

In December 2020, Argentina approved a new abortion law following decades of feminist and social advocacy. This paper presents qualitative findings from interviews and focus group discussions with people in local communities focusing on how individuals of reproductive age access and communicate sexual and reproductive health information, particularly regarding abortion. Sixteen in-depth interviews were conducted with key informants working in the field of SRHR and four focus group discussions took place with cisgender women and girls, transmasculine people and non-binary people of reproductive age. We found that information exchange and communication about sexual and reproductive health issues, particularly abortion, took place mainly through informal social networks engaging with activists and feminist grass-root organisations. These informal social networks were built on trust as a collective affect that enabled open communication about abortion. Information sharing through word of mouth, in person and via digital means using different social media platforms, is an important means of information sharing and communication in Argentina. Monitoring the implementation of abortion policies in this country should include investigating the impact of people accessing abortion through informal social networks in terms of abortion pathways and intersections with the formal health system.

Age Differences in Consulting Others During Decision Making.

Many choices are made in the context of one's social network, but age differences in consulting others during decision-making remain underexplored. This pre-registered study examined age differences in the composition of decision-related social networks and associated social preferences and motivations. Based on prior findings regarding age differences in information-seeking and socioemotional preferences, we predicted that with advanced age people would consult fewer and more emotionally close social partners, consult them less frequently, rate consultations as more helpful, and prioritize social goals during decision-making. An adult lifespan sample (N = 485; Mage = 51.08; SDage = 19.63, rangeage = 18-96 years) considered hypothetical choices and reported how many and what types of people they would consult and how often they would consult them. They also identified their most important decision consultants and evaluated interactions with those individuals. As predicted, age was associated with consulting fewer people less frequently and this was not explained by having a smaller range of potential consultants in one's network. Contrary to predictions, the proportion of close social partners in decision networks and the perceived helpfulness of consultants did not vary significantly by age. Moreover, older adults were less likely than younger adults to prioritize relationship quality over decision quality. Controlling for potential covariates did not diminish the observed age effects. These findings align with the prior literature on age-related decrements in pre-decisional information seeking but suggest that age-related preferences for close social partners and socioemotional goals do not extend to decision-related consultations.

Removing environmental barriers to independent living: A feasibility randomised controlled trial targeting people ageing with long-term physical disabilities

Introduction: People ageing with long-term physical disabilities face unique challenges to maintaining independence. We developed a novel, evidence-based intervention – Removing Environmental Barriers to Independent Living – to support participation and reduce falls. Methods: To examine Removing environmental barriers to independent living’s feasibility and estimate its magnitude of efficacy, we conducted a single-blinded randomised controlled trial. Fifty participants who were aged 45–65 years with a physical disability for at least 5 years were randomised to intervention ( n = 24) or control ( n = 26). Activity performance, environmental barriers to performance, community participation, environmental fall hazards and fall prevention behaviours were assessed at baseline and at 6-month follow-up. Dose, adherence, fidelity and cost were examined. Linear mixed-effects models for repeated measures were used to assess the effects of time, group and group by time interaction on the continuous outcomes. Results: Removing environmental barriers to independent living had high fidelity and adherence and a low implementation cost. There were trends for greater improvements in activity limitations and activity performance among intervention versus control participants. Conclusion: Removing environmental barriers to independent living is a feasible intervention with high fidelity and adherence. Findings trended towards greater improvements in activity performance for intervention participants. Results could inform future planning for a larger pragmatic trial.

Subjective Well-Being of Parents and Childless People in Older Age in Germany

AbstractThe growing number of older childless individuals in Western societies has raised concerns about their subjective well-being. In this study, we scrutinize the subjective well-being of parents and childless individuals aged 60 years and older. We examine subjective well-being as a multi-dimensional construct encompassing life satisfaction, positive affect, and negative affect. Based on the value-of-children approach, we hypothesize that childless individuals experience lower subjective well-being than parents and that the disparity in well-being differs with age, gender, and the quality of the parent-child relationship. For our analysis, we use data from a nationally representative sample of adults aged 60 years and older (n = 10,682) drawn from the German Ageing Survey. Our findings from random effects regression models show that childless individuals report lower life satisfaction, less positive affect, and more negative affect than parents. These associations are larger for men than for women but do not vary significantly across age groups. Furthermore, our results suggest that the benefits of parenthood strongly depend on the quality of the parent-child relationship. Childless people report lower subjective well-being than parents with a close emotional bond with their children, but similar or even higher subjective well-being than parents with an emotionally distant parent-child relationship. In sum, our study indicates that childless people experience, on average, lower well-being across all three dimensions of subjective well-being in older age. However, under specific circumstances, childless individuals may fare better than parents.

Changes in Innate Immunity and Microbiome in Different Aging Phenotypes.

The indicators of innate immunity and the composition of the microbiome in the nasopharyngeal mucosa in centenarians with different aging phenotypes were analyzed. A significant increase in the expression of pattern-recognizing receptor genes (TLR2, TLR4, and NLRP3) and proinflammatory cytokines (IL1B, IL18) was shown in the group of centenarians with pathological aging phenotype. In centenarians with successful aging phenotype, increased diversity of the microbiome composition was observed. At the same time, a moderate inverse correlation was found between an increase in the growth of the commensal bacterium Streptococcus salivarius and a decrease in the expression of proinflammatory cytokine genes IL1B and IL18. These findings can serve as biomarkers for the timely identification of the phenotype of aging in senile and elderly people.

State-level anti-transgender laws increase past-year suicide attempts among transgender and non-binary young people in the USA.

From 2018 to 2022, 48 anti-transgender laws (that is, laws that restrict the rights of transgender and non-binary people) were enacted in the USA across 19 different state governments. In this study, we estimated the causal impact of state-level anti-transgender laws on suicide risk among transgender and non-binary (TGNB) young people aged 13-17 (n = 35,196) and aged 13-24 (n = 61,240) using a difference-in-differences research design. We found minimal evidence of an anticipatory effect in the time periods leading up to the enactment of the laws. However, starting in the first year after anti-transgender laws were enacted, there were statistically significant increases in rates of past-year suicide attempts among TGNB young people ages 13-17 in states that enacted anti-transgender laws, relative to states that did not, and for all TGNB young people beginning in the second year. Enacting state-level anti-transgender laws increased incidents of past-year suicide attempts among TGNB young people by 7-72%. Our findings highlight the need to consider the mental health impact of recent anti-transgender laws and to advance protective policies.

Effect of Intranasal Insulin on Olfactory Recovery in Patients with Anosmia .

Olfactory dysfunction, defined as either a complete or partial impairment of smell, is a common condition that may substantially affect a person’s quality of life and is frequently difficult to treat. Physical activity, heredity, nutrition, smoking, head trauma, medical treatments, and virus exposure all influence one’s capacity to smell. Hyposmia or anosmia, or loss of smell, affects 3% to 20% of the population. Intranasal insulin can improve cognitive performance, reduce food intake, and boost olfactory thresholds in healthy individuals. As people age, they are more likely to experience olfactory dysfunction, which may be affected by a variety of reasons, such as acute and chronic sino-nasal illness, upper respiratory infections, toxic chemical exposure, and degenerative diseases. About ten percent of those over 65 develop olfactory impairment, which can range from mild loss to total anosmia. Insulin resistance in the central nervous system has been linked to conditions like type II diabetes, Alzheimer’s disease, obesity, and poor odor identification. Reduced odor perception may contribute to reduced olfactory function in anosmic patients.

The care of non-institutionalized ADL-dependent people in the Orcasitas neighborhood of Madrid (Spain) during the Covid-19 pandemic and its relationship with social inequalities, intergenerational dependency and survival.

Mortality among people with dependency to perform basic activities of daily living (ADL) is higher than that of non-dependent people of the same age. Understanding the evolutionary course and factors involved in non-institutionalized ADL dependency, including the influence of the family structure that supports this population, would contribute to improved health planning. A longitudinal study carried out in the ADL-dependent population of the Orcasitas neighborhood, Madrid (Spain), between June 2020, when the nationwide COVID-19 lockdown ended, and June 2023. A total of 127 patients participated in the study, 78.7% of whom were women and 21.3% were men. Risk analysis was performed via odds ratios (OR) and hazard ratios (HR). Survival analysis was performed using Cox regression. A total of 54.33% of the ADL-dependent persons did not live with their adult children and 45.67% did, being associated living independently with economic capacity and the married marital status but not with the dependency level. In women, being married increased the probability of living independently of their adult children (OR = 12.632; 95% CI = 3.312-48.178). Loss of mobility (OR = 0.398; 95% CI = 0.186-0.853), economic capacity of the dependent (HR = 0.596; 95% CI = 0.459-0.774), and living independently and having better economic capacity (HR = 0.471; 95% CI = 0.234-0.935) were associated with 3-year survival. Those who lived with their adult children had a worse autonomy profile and higher mortality (HR = 1.473; 95% CI = 1.072-2.024). Not being employed, not being married, and not owning a home were significantly associated with being an essential family caregiver. Caregivers were mostly women (OR = 1.794; 95% CI = 1.011-3.182). Among ADL-dependent persons, economic capacity influenced the ability to living independently and affected survival after 3 years. Loss of mobility (wheelchair use) was a predictor of mortality. Social inequalities promote that adult children end up as essential family caregivers. This generates reverse dependency and maintains a vulnerability that is transmitted from generation to generation, perpetuating social and gender inequalities. Dependent parent care in this cohort maintained an archaic pattern in which the eldest daughter cared for her parents. This study made it possible to show that ADL dependence is accompanied by complex interrelationships that must be considered in socio-health planning.

Beyond “Pressure”: Peer Influences on e-Cigarette Use in Young Australian Narratives of Vaping

Background In the early 2020s, Australian media and public health organizations described the rapid rise in youth e-cigarette uptake, portraying this as a “peer pressure” problem wherein vulnerable young people were being led or bullied into vaping by the “cool” kids. Yet, the peer pressure framing of vaping fails to account for young people's rituals of nicotine consumption and ways social drug economies are organized. Methods In 2023, we conducted qualitative interviews and ethnographic research with 24 young people ages 17 to 25, both vapers and nonvapers, in New South Wales, Australia. We investigated their embodied experiences of vaping, observations of peers’ vaping practices, and beliefs about vaping policy. We analyzed their accounts for themes and here report our findings, illustrated with participants’ quotes and an ethnographic portrait of a Sydney high school vape seller. Results The notion that young people are “pressured” into vaping lacked emic meaning for our participants. Their accounts reveal three ways that vaping is social beyond “pressure.” First, social vape market offers entrepreneurial teens money-earning opportunities, mediated by social networks and markers of peer esteem, prestige, and trust. Second, vapes are exchanged as both gifts and commodities in sharing economies, offering social opportunities and scripts for recreational interactions. Third, e-cigarettes as material objects provide esthetic and gustatory pleasures that are both individually enjoyed and socially performed in rituals of taste and display. Discussion These three perspectives on the sociality of vaping help nuance our understanding of how and why young people vape, and also suggest why public health outreach efforts may not be effective when they reduce youth vaping uptake to peer pressure. As youth vape use is on the rise in Australia, these perspectives matter for understanding this important social phenomenon and may help policy development move beyond simplifications of youth cultural motivations.

The BRIDGE project: a feasibility randomised controlled trial of brief, intensive assessment and integrated formulation for young people (age 14-24) with features of borderline personality disorder (Protocol).

Borderline personality disorder (BPD) is a severe mental disorder that is characterised by a pervasive pattern of instability of interpersonal relationships, self-image, and mood as well as marked impulsivity. BPD has its peak incidence and prevalence from puberty through to emerging adulthood. BPD is a controversial diagnosis in young people. Commonly, young people with BPD are under-diagnosed, untreated, are not in employment or training and are estranged from their families. Yet, they have complex needs and are at high suicide risk. To assess the feasibility of conducting a randomised controlled trial (f-RCT) of a BRIDGE, a brief intervention programme for young people (age 14-24) with BPD symptoms (sub-threshold or threshold) in a community sample from Scotland, UK. Forty young people (age 14-24) meeting criteria for BPD symptoms, will be randomised in a 1:1 ratio to receive either a) the BRIDGE intervention plus service-as-usual or b) service-as-usual alone. Follow up will be 12 weeks and 24 weeks post-intervention. The study is carried out between 2021 to 2024. The two primary outcomes of the MQ funded, BRIDGE project (f-RCT) are i. recruitment rates and ii. retention rates. The study will present the acceptability and appropriateness of our putative outcome measures for a future definitive randomised controlled trial (d-RCT). Young people with BPD benefit from good clinical care and targeted intervention, however are regularly missed or mislabelled. The community based feasibility trial would provide initial evidence of variable needs of young people with complex needs, who maybe missed or excluded from services as they don't "fit" a model/diagnosis. Workable multi-agency service model proposed in the trial would be a major advance in understanding care pathways regardless of trial outcome. ClinicalTrial.gov, identifier NCT05023447.

The Night Divide: Gender-Specific Trajectories of Sleep Disturbances Among Multiple Cohorts of Aging Populations.

Sleep disturbances in later life are prevalent and can profoundly impact health and well-being. However, whether and how trajectories of sleep disturbances vary as people age by gender and across age cohorts remains unexplored. This study uses an integrated theoretical framework to understand gender-specific trajectories of sleep disturbances over time and how they vary by cohort. Accelerated longitudinal data from the Health and Retirement Study (N=20,947; M=8,562, F=12,385) was analyzed to investigate gender-specific trajectories of sleep disturbances and potential cohort variations. Weighted growth curve model was applied with sociodemographic and health-related variables. Men and women were analyzed separately. Results showed that sleep disturbances increased with age in men, but not in women. Also, younger cohorts of men increased sleep disturbances over time at a slower rate than older cohorts. Among men, health profiles accounted for the association between age and sleep disturbances. Among men and women, younger cohorts started with higher levels of sleep disturbances around midlife. When examining specific types of sleep disturbance separately, having trouble falling asleep was the type that drove the observed patterns in men. For women, there was no association between age and any individual type of sleep disturbance. This study shows that men, rather than women, tend to experience increasing sleep disturbances with age, with some variations across cohorts. These findings imply that different strategies for men and women and targeted timing over the life course would be most effective at promoting sleep health in American men and women.
