The prospective association between illicit drug use and nonprescription opioid use among vulnerable adolescents.
In recent years, more than half of all drug overdose deaths in United States involved an opioid. To address this epidemic, antecedents to opioid misuse must be identified and empirically validated. The objective of the current investigation was to examine whether illicit drug use was prospectively associated with nonprescription opioid use among adolescents from a vulnerable population with a greater prevalence of substance abuse. ⋯ Multilevel, covariate-adjusted logistic regression models indicated that the odds of experimentation with nonprescription opioids was greater among adolescents who had used illicit drugs or illicit drugs excluding marijuana. Nonmedical marijuana use alone was a statistically significant predictor in unadjusted but not covariate-adjusted models. While prior studies have examined the progression from nicotine, alcohol, and marijuana use to nonprescription opioid use, the present findings emphasize the importance of illicit drug use as a detectable and empirically supported risk factor for future opioid misuse.

The bidirectional association between sleep and physical activity: A 6.9 years longitudinal analysis of 38,601 UK Biobank participants.
Although physical activity and sleep may influence each other, little is known about the bidirectional association of these two behaviors. The present analyses included 38,601 UK Biobank participants (51% female, 55.7 ± 7.6 years old, 6.9 ± 2.2 years of follow-up). Physical activity was categorized by the weekly metabolic equivalent of task minutes (highly active: ≥ 1200; active: 600 to <1200; inactive: < 600), and sleep patterns were determined using a composite score of healthy sleep characteristics: morning chronotype, adequate sleep duration (7-8 h/d), never or rare insomnia, never or rare snoring, and infrequent daytime sleepiness. ⋯ Compared to individuals highly active at both time points, being physically inactive at baseline and reducing physical activity over time were both associated with higher odds for poor sleep at follow-up. In conclusion, sleep improvements over time benefitted physical activity at follow-up, while reduced physical activity had a detrimental effect on sleep patterns at follow-up. Our results provide scope for interventions to concurrently target physical activity and sleep.

From the individual viewpoint, active aging refers to the ability of older persons, depending on their goals, functional capacity and opportunities, to engage in desired activities. This study investigated the role of health literacy in active aging among persons differing in their number of chronic conditions. Data were collected from 948 individuals, 57% women, aged 75, 80 and 85 in 2017-2018 in the city of Jyväskylä in Central Finland. ⋯ Higher health literacy can enable older persons, including those with multiple chronic conditions, to maintain higher levels of active aging. As more people are projected to live with chronic conditions to older ages, health literacy may help them to cope with illnesses and functional limitations and lead a fulfilling life. These cross-sectional findings lay a foundation for future prospective and experimental studies on health literacy and active aging.

Associations between e-cigarette pack size and vaping frequency among U.S. adults.
Little research exists on the association between e-cigarette pack quantity and use. We examined whether using e-cigarettes every day or somedays was associated with purchasing e-cigarettes by the box/pack or as singles. Data are from the 2018-2019 Tobacco Use Supplement to the Current Population Survey, analyzed in 2020. ⋯ Those who reported purchasing by the box/pack had greater odds of every day e-cigarette use compared to some day use (Adjusted Odds Ratio: 1.36, 95% CI: 1.09, 1.68). This finding held for both males, females, and all device types. These findings present a first step in determining the relationship between e-cigarette pack size and use behavior.

Investigating the environmental, behavioural, and sociodemographic determinants of attendance at a city-wide public health physical activity intervention: Longitudinal evidence over one year from 185,245 visits.
Understanding the determinants of attendance at public health interventions is critical for effective policy development. Most research focuses on individual-level determinants of attendance, while less is known about environmental-level determinants. Data were obtained from the Leeds Let's Get Active public health intervention in Leeds, England. ⋯ Finally, calendar month was the most important determinant of daily attendance. This longitudinal study highlights the importance of both individual and environmental determinants in predicting various aspects of attendance. It has implications for strategies aiming to increase attendance at public health interventions.
