To examine whether bedtime is associated with usual sleep duration and eating behaviour among adolescents, emerging adults and young adults. Cross-sectional multivariable regression models, stratified by developmental stage, to examine: (1) association between bedtime and sleep duration and (2) associations between bedtime and specific eating behaviours at each developmental period, controlling for sleep duration. All models adjusted for sociodemographic characteristics, depressive symptoms and screen time behaviours. National Longitudinal Study of Adolescent to Adult Health, waves I-IV, USA. A national probability sample surveyed in adolescence (aged 12-18 years, wave I: 1994-1995, n 13 048 and wave II: 1996, n 9438), emerging adulthood (aged 18-24 years, wave III: 2001-2002, n 9424) and young adulthood (aged 24-34 years, wave IV: 2008, n 10 410). Later bedtime was associated with shorter sleep duration in all developmental stages, such that a 1-h delay in bedtime was associated with 14-33 fewer minutes of sleep per night (Ps < 0·001). Later bedtime was also associated with lower odds of consuming healthier foods (i.e. fruits, vegetables; range of adjusted OR (AOR), 0·82-0·93, Ps < 0·05) and higher odds of consuming less healthy foods and beverages (i.e. soda, pizza, desserts and sweets; range of AOR, 1·07-1·09, Ps < 0·05). Later bedtime was also associated with more frequent fast-food consumption and higher sugar-sweetened beverage consumption (Ps < 0·05). Later bedtime was associated with shorter sleep duration and less healthy eating behaviours. Bedtime may be a novel behaviour to address in interventions aiming to improve sleep duration and dietary intake.

Research suggests that sleep duration and obesity are related, but the direction of this association remains uncertain. We applied autoregressive cross-lag models to evaluate the directionality of the relationship between sleep duration and BMI from adolescence through emerging and young adulthood, life stages where the risk for developing obesity are particularly high. Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we examined sex-stratified associations between sleep duration and BMI in this cohort from adolescence (ages 12–18, year 1996), to emerging adulthood (ages 18–24, 2001–2002), to young adulthood (ages 24–32, 2008), controlling for key confounders. For both males and females, higher BMI during an earlier developmental stage was associated with shorter sleep duration in the subsequent stage (both Bs = −0.02, ps < 0.01). However, sleep duration at an earlier developmental stage was not associated with BMI at the subsequent stage. Findings suggest that researchers should be cautious when interpreting cross-sectional relationships between sleep and BMI, as higher BMI may precede shorter sleep during adolescence to young adulthood. Researchers may also wish to account for potential bi-directional associations when modeling sleep and BMI using longitudinal data.

ObjectiveEvidence suggests peer support (PS) is as an effective strategy for enhancing prevention and control of chronic and infectious diseases, including cancer. This systematic scoping review examines the range and variety of interventions on the use of PS across the cancer care continuum.MethodWe used a broad definition of PS to capture a wide-range of interventions and characterize the current status of the field. Literature searches were conducted using PubMed, SCOPUS, and CINAHL to identify relevant articles published from January 2011 to June 2016. We screened the title and abstracts of 2087 articles, followed by full-text screening of 420 articles, resulting in a final sample of 242 articles of which the most recent 100 articles were reviewed (published June 2014 to May 2016).ResultsA number of the recent intervention studies focused on breast cancer (32%, breast cancer only) or multiple cancer sites (23%). Although the interventions spanned all phases of the cancer care continuum, only 2% targeted end-of-life care. Seventy-six percent focused on clinical outcomes (e.g., screening, treatment adherence) and 72% on reducing health disparities. Interventions were primarily phone-based (44%) or delivered in a clinic setting (44%). Only a few studies (22%) described the impact of providing PS on peer supporters.ConclusionPS appears to be a widely used approach to address needs across the cancer care continuum, with many opportunities to expand its reach.

Background. Health disparities are aggravated when prevention and care initiatives fail to reach those they are intended to help. Groups can be classified as hardly reached according to a variety of circumstances that fall into 3 domains: individual (e.g., psychological factors), demographic (e.g., socioeconomic status), and cultural–environmental (e.g., social network). Several reports have indicated that peer support is an effective means of reaching hardly reached individuals. However, no review has explored peer support effectiveness in relation to the circumstances associated with being hardly reached or across diverse health problems. Objectives. To conduct a systematic review assessing the reach and effectiveness of peer support among hardly reached individuals, as well as peer support strategies used. Search methods. Three systematic searches conducted in PubMed identified studies that evaluated peer support programs among hardly reached individuals. In aggregate, the searches covered articles published from 2000 to 2015. Selection criteria. Eligible interventions provided ongoing support for complex health behaviors, including prioritization of hardly reached populations, assistance in applying behavior change plans, and social–emotional support directed toward disease management or quality of life. Studies were excluded if they addressed temporally isolated behaviors, were limited to protocol group classes, included peer support as the dependent variable, did not include statistical tests of significance, or incorporated comparison conditions that provided appreciable social support. Data collection and analysis. We abstracted data regarding the primary health topic, categorizations of hardly reached groups, program reach, outcomes, and strategies employed. We conducted a 2-sample t test to determine whether reported strategies were related to reach. Results. Forty-seven studies met our inclusion criteria, and these studies represented each of the 3 domains of circumstances assessed (individual, demographic, and cultural–environmental). Interventions addressed 8 health areas, most commonly maternal and child health (25.5%), diabetes (17.0%), and other chronic diseases (14.9%). Thirty-six studies (76.6%) assessed program reach, which ranged from 24% to 79% of the study population. Forty-four studies (94%) reported significant changes favoring peer support. Eleven strategies emerged for engaging and retaining hardly reached individuals. Among them, programs that reported a strategy of trust and respect had higher participant retention (82.8%) than did programs not reporting such a strategy (48.1%; P = .003). In 5 of the 6 studies examining moderators of the effects of peer support, peer support benefits were greater among individuals characterized by disadvantage (e.g., low health literacy). Conclusions. Peer support is a broad and robust strategy for reaching groups that health services too often fail to engage. The wide range of audiences and health concerns among which peer support is successful suggests that a basis for its success may be its flexible response to different contexts, including the intended audience, health problems, and setting. Public health implications. The general benefits of peer support and findings suggesting that it may be more effective among those at heightened disadvantage indicate that peer support should be considered in programs intended to reach and benefit those too often hardly reached. Because engendering trust and respect was significantly associated with participant retention, programs should emphasize this strategy.

BackgroundChronically absent students miss learning opportunities at school, and as a result, may suffer academically and socially. Student absenteeism is rising across the USA, with 14%–30% of K-12 students being chronically absent (missing ≥10% of school days) each year. In 2012, Michigan started Pathways to Potential (P2P)—placing caseworkers in public schools to address the material needs of students that interfere with attendance. In this study, we evaluated the effect of P2P on chronic absenteeism in public schools across Michigan.MethodsOur quasi-experimental study included 160 Michigan K-12 public schools that began implementing P2P between 2012 and 2016. We evaluated the effect of P2P on chronic absenteeism using administrative data for academic years 2008–2009 through 2018–2019. We used a staggered interrupted time series (ITS) analysis, first modelling a simple ITS for each school, and then pooling effect estimates using random effects meta-analysis. We estimated meta-regressions to investigate heterogeneous treatment effects.ResultsResults suggest P2P reduced chronic absenteeism rates by 7.88% (incidence rate ratio=0.92 (95% CI 0.88 to 0.96)), preventing 21 students from being chronically absent per school per year (95% CI 17.52 to 24.95). There was significant heterogeneity, with greater effects for schools that received a higher P2P dose, were in the eastern region of the state, had wealthier student bodies, and were less racially diverse.ConclusionThis school-based intervention represents a feasible and effective programme for preventing chronic absenteeism. Further standardising the programme, while ensuring P2P can address diverse needs, may produce more consistent results across schools.

The objective of this study was to assess parents’ firearm storage behaviors during the COVID-19 pandemic and characterize reasons why some parents made their firearms more accessible during this time. In June-July 2020, the study team conducted the FACTS National Survey—a cross-sectional, web-based, survey of 2,924 parents and their teens (ages14–18) regarding firearm-related practices. We weighted descriptive analyses to be nationally representative of parents of teens in the United States. We utilized qualitative thematic analysis to identify parents’ reasons for making firearms more accessible. Five percent of firearm-owning parents of teens reported making their firearms more accessible during the beginning of the COVID-19 pandemic. Reasons why parents increased the ease of firearm access included: (1) Increased civil unrest and riots; (2) Threat of home invasion and/or crime victimization; (3) Fear of panic and the unknown; and (4) Easier access and greater protection, threat unspecified. Some parents—largely motivated by fear—chose to store firearms in a more accessible manner during the beginning of the COVID-19 pandemic to protect their family against possible external threats. Understanding the fear that motivates parents’ decisions regarding storage practices might aid interventions focused on harm reduction and safer storage.

ObjectiveThis study aims to characterise the motivations of firearm owners and examine whether firearm ownership motivations and carriage varied by state stand your ground law status. MethodsUsing a nationally representative survey of US adults in 2023, we asked firearm owners (n=2477) about their firearm motivations and behaviours, including reason(s) for ownership.ResultsOf all firearm owners, 78.8% (95% CI 76.0% to 81.0%) owned a firearm for protection, and 58.1% (95% CI 54.3% to 62.0%) carried a firearm outside their home in the last 12 months. Firearm ownership for protection was not significantly associated with stand your ground laws, but firearm carriage was more prevalent in states with stand your ground laws (50.1% (95% CI 47.0% to 53.0%) vs 34.9% (95% CI 25.0% to 46.0%)). Gender (women) and race (minority groups) emerged as key correlates for firearm ownership for protection (vs other ownership motivations). For example, black and Asian women (98.8%) almost exclusively owned firearms for protection.ConclusionsProtection was the dominant reason for firearm ownership in 2023, motivating 65 million Americans to own firearms and appealing to different strata of the population.

Peer support from community health workers, promotores de salud, and others through community and health care organizations can provide social support and other assistance that enhances health. There is substantial evidence for both the effectiveness and the cost-effectiveness of peer support, as well as for its feasibility, reach, and sustainability. We discuss findings from Peers for Progress, a program of the American Academy of Family Physicians Foundation, to examine when peer support does not work, guide dissemination of peer support programs, and help integrate approaches such as e-health into peer support. Success factors for peer support programs include proactive implementation, attention to participants' emotions, and ongoing supervision. Reaching those whom conventional clinical and preventive services too often fail to reach; reaching whole populations, such as people with diabetes, rather than selected samples; and addressing behavioral health are strengths of peer support that can help achieve health care that is efficient and of high quality. Challenges for policy makers going forward include encouraging workforce development, balancing quality control with maintaining key features of peer support, and ensuring that underresourced organizations can develop and manage peer support programs.

To describe and identify the correlates of firearm purchasing at the beginning of the COVID-19 pandemic among US families with teenagers. In June–July 2020, we conducted a national survey of 2924 parents and their teenagers in the US. We report results from this survey to describe firearm purchasing behaviors following the start of the COVID-19 pandemic and investigate correlates of purchasing. Between the beginning of the pandemic and July 2020, 10% of households with teenagers purchased a firearm, and 3% became first-time firearm-owning households. Among firearm-owning households, firearm storage was associated with purchasing such that households that stored at least one firearm loaded and unlocked were more likely to purchase a firearm (OR: 2.02[1.07–3.79]) compared to households that stored all firearms unloaded and/or locked. Firearms purchased at the beginning of the pandemic were more likely to go to homes where at least one firearm was stored loaded and unlocked, which may contribute to increased risk for teen firearm injury and death.

WeChat is the most popular social media platform in mainland China, with over 1 billion active users. Although social media is widely used in professional healthcare education in western countries, research on WeChat-based education in healthcare in mainland China is disparate and not systematic. The current study seeks to address this gap. A scoping review was conducted to systematically describe studies of WeChat use in professional healthcare education. A comprehensive search involving three international databases in English and Chinese literature was conducted in April 2019. Articles were retained in this study if they were original studies that used WeChat as a tool to facilitate healthcare education in mainland China. 25 studies met the inclusion criteria and the majority of studies were either experimental or quasi-experimental. WeChat was used in both university settings and hospital settings. Hybrid education-which integrates WeChat education and face-to-face education-was more common in university settings, whereas hospitals used a combination of hybrid and WeChat-only strategies. Significant heterogeneity was observed regarding the type of accounts and methods for delivering content and facilitating online conversations. A majority of studies found positive outcomes with WeChat education. This scoping review addressed a large gap in knowledge about the usage of WeChat in professional healthcare education. Of the existing studies identified, we observed considerable promise for future practice. We provide additional suggestions for conducting future research involving patients and other helping professionals in healthcare education to expand the usage of WeChat.
