Objective: To examine how alcohol availability, overserving, and enforcement in recreational and social settings are related to alcohol misuse and alcohol-impaired driving among young adults in Victoria, Australia and Washington State, United States.

Method: Longitudinal data came from 1,430 participants in Victoria (n = 757; 52% female) and Washington (n = 673; 53% female), surveyed in 2014 (age 25) and 2018 (age 29) from the International Youth Development Study, a population-based, cross-national study to examine factors influencing substance use. Path modeling tested associations between age 25 perceptions of the alcohol environment, age 25 social alcohol consumption, and age 31 alcohol-related harms.

Prior studies suggest that adult supervised drinking in adolescence predicts greater adolescent alcohol misuse. Long-term follow up data examining how adult supervised drinking during adolescence relates to alcohol misuse in adulthood are lacking. Longitudinal data from the International Youth Development Study tested associations between adult supervised drinking during adolescence (ages 13-16; 2002-2004) and adult alcohol misuse (ages 25-31; 2014, 2018, 2020).

Some universal prevention programs, such as Raising Healthy Children (RHC), have shown persisting and wide-ranging benefits in adulthood, long after the intervention has ended. Recent studies suggest that benefits may continue into the next generation as well. This study examines whether the RHC intervention, delivered in childhood, may promote healthy family functioning among participants who now have families of their own.

This study tested whether effects of a preventive intervention delivered in elementary school showed benefits for the young adult offspring of intervention recipients over 20 years later. The Raising Healthy Children (RHC) intervention, trialed in 18 public schools in Seattle, Washington, from 1980-1986 (grades 1-6), sought to build strong bonds to family and school to promote school success and avoidance of substance use and illegal behavior. Four intervention groups were constituted: full, late, parent training only, and control.

Article Synopsis
  • A study explored how cannabis use is related to the misuse of pain relievers among young adults in Washington State, where cannabis is legal.
  • The analysis involved 4,236 participants aged 18-25, tracking their cannabis use and instances of pain reliever misuse over three years.
  • Results indicated that both non-medical and medical cannabis use were linked to a higher risk of misusing pain relievers, challenging the belief that cannabis might help reduce opioid misuse.

People who experience social marginalization and vulnerability have uniquely complex health needs and are at risk of poor health outcomes. Regression analyses using longitudinal data from a cross-national, population-based sample of young adults participating in the International Youth Development Study, tested associations between social marginalization and vulnerabilities and physical health, mental health, and substance use outcomes. Participants from Victoria, Australia, and Washington State in the US were surveyed at ages 25 (2014) and 29 years (2018; = 1944; 46.

Few studies examining the effects of neighborhood exposures have accounted for longitudinal residential history. This study examined associations of body mass index (BMI, kg/m) with neighborhood-level walkability and poverty, both assessed concurrently and cumulatively in the years leading up to BMI assessment. Participants (N = 808) were from a cohort study of individuals originally recruited from public schools in Seattle, Washington, in fifth grade in 1985.

Article Synopsis
  • The study aimed to analyze telehealth trends in a workers' compensation system during COVID-19, focusing on how different sociodemographic factors influenced its use.
  • Telehealth utilization rose from 1.2% pre-pandemic to a peak of 8.8% in April 2020, then stabilized around 3.6% by late 2020, with significant variations based on age, sex, and other demographic factors.
  • The findings highlight the need for further research on access disparities in telehealth among injured workers, indicating shifts in service delivery during the pandemic.

Objective: This study aims to describe the frequency and characteristics of anticonvulsant medication treatments initiated in the neonatal period.

Study Design: We analyzed a cohort of neonates with a seizure diagnosis who were discharged from institutions in the Pediatric Health Information System between 2007 and 2016. Adjusted risk ratios and 95% confidence intervals for characteristics associated with neonatal (≤ 28 days postnatal) anticonvulsant initiation were calculated via modified Poisson regression.

Background: Patent ductus arteriosus (PDA), the most commonly diagnosed cardiovascular condition in preterm infants, is associated with increased mortality and harmful long-term outcomes (chronic lung disease, neurodevelopmental delay). Although pharmacologic and/or interventional treatments to close PDA likely benefit some infants, widespread routine treatment of all preterm infants with PDA may not improve outcomes. Most PDAs close spontaneously by 44-weeks postmenstrual age; treatment is increasingly controversial, varying markedly between institutions and providers.

Objective: To evaluate the short-term effects of feed fortification, feed volume increase, and PRBC transfusion on the odds of developing NEC.

Study Design: Case-crossover study of neonatal intensive care infants born at ≤ 32 weeks' gestation who were admitted to 5 central Ohio intensive care units from January 2012-July 2016 and developed NEC Bell Stage ≥2. Each patient served as their own control, with exposure during the 48-hour period just prior to NEC onset (hazard period) being compared to a preceding 48-hour control period, thus eliminating confounding by patient factors fixed between both intervals.
