Cardiovascular risk and functional burden at midlife: Prospective associations of isotemporal reallocations of accelerometer-measured physical activity and sedentary time in the CARDIA study.
Cardiovascular risk and functional burden, or the accumulation of cardiovascular risk factors coupled with functional decline, may be an important risk state analogy to multimorbidity. We investigated prospective associations of sedentary time (ST), light intensity physical activity (LPA), and moderate to vigorous intensity physical activity (MVPA) with cardiovascular risk and functional burden at midlife. Participants were 1648 adults (mean ± SD age = 45 ± 4 years, 61% female, 39% Black) from Coronary Artery Risk Development in Young Adults (CARDIA) who wore accelerometers in 2005-2006 and 2015-2016. ⋯ Reallocating 24 min of LPA to MVPA was associated with a 14% lower odds of cardiovascular risk and functional burden (OR: 0.86; CI: 0.75, 0.99). In longitudinal isotemporal models, similar beneficial associations were observed when 10-year increases in MVPA replaced time in ST or LPA. Findings suggest that maintaining an MVPA dose reflecting daily physical activity recommendations in early midlife is associated with lower odds of cardiovascular risk and functional burden later in midlife.

Driving under the influence of cannabis is a growing public health concern among young people. This study assessed the prevalence of cannabis-impaired driving and its related sociodemographic, psychological, and knowledge-based correlates among Canadian adolescents. The sample for this study were drawn from the 2017 Ontario Student Health and Drug Use Survey (OSDUHS), consisting of high school students with valid driver's licenses (mean age = 16.8, SD = 0.71) who were asked about their driving behaviors, drug use, and attitudes regarding cannabis use (N = 1161). ⋯ Other correlates of driving after cannabis user were risky driving behaviors, including past-year texting and driving and driving after alcohol use. There are various correlates of driving under the influence of cannabis, including attitudes related to cannabis which may be amenable to intervention. Future efforts should continue to monitor the prevalence of cannabis-impaired driving in this population and determine whether changes in students' attitudes surrounding cannabis are linked to behavioural changes.

The adherence to school meals is associated with a lower occurrence of obesity among Brazilian adolescents.
This study aimed to verify the association between adherence to meals from the Brazilian National School Feeding Program (PNAE) and obesity indicators among adolescents. Data from 12,373 students attending public schools from the 2015 National Survey of School Health were used. Adherence to school meals was assessed using a self-administered questionnaire and classified as null (zero/rarely), low (1-2×/week), moderate (3-4×/week), and high (5×/week). ⋯ An inverse and dose-response association were observed between adherence to the PNAE meals and obesity indicators. Adolescents with high adherence to school meals (5×/week) had a 0.10 lower BMI Z-score (coefficient = -0.10, CI -0.17;-0.03), 11% less prevalence of overweight (PR = 0.89, CI 0.80;0.99) and 24% less prevalence of obesity (PR = 0.76, CI 0.62;0.93) than those with a lower adherence (<5×/week). Our results showed that the adherence to PNAE meals may contribute to obesity prevention in Brazil.

Sociodemographic and psychological characteristics associated with discrepancy between body satisfaction and weight change among adolescents.
This study aimed to describe the discrepancy between body satisfaction change and weight change among adolescents following a 2-year school-based intervention, to identify associated sociodemographic factors, and to explore possible associations with perceived health indicators. We used data from a northeastern France representative adolescents sample (14-18 years old) who participated in the PRALIMAP (PRomotion de l'ALIMentation et de l'Activité Physique) study (2006-2009). Weight change was measured by the change in body mass index z-score from the start to the end of the study. ⋯ Body satisfaction change was rather in line with anxiety, depression and quality of life changes than weight change. Body satisfaction change should be considered in overweight and obesity prevention interventions alongside body weight change, and could be used as indicator of long-term behavior maintenance. Clinical trials registry and number:ClinicalTrials.gov (NCT01688453).

The cumulative effect of multiple dimensions of lifestyle on risky drinking during the Covid-19 pandemic.
Lifestyle impacts morbidity and mortality worldwide. Herein, we evaluated the association of a multidimensional lifestyle measure and its domains (diet/nutrition, substance use, physical activity, social, stress management, sleep, environmental exposure) with risky drinking. Also, we analyzed the cumulative effect of unhealthy domains in the likelihood of presenting risky drinking. ⋯ The higher the number of unhealthy domains, the higher the likelihood of presenting risky drinking: adjusted odds ratio (aOR) for risky drinking was 1.15 (IC95% 0.98-1.35) and 23.42 (IC95% 3.08-178.02) for those presenting worse lifestyle in 1 and 5 domains, respectively. Finally, interactions suggest that improvement in lifestyle domains would have a larger effect in Spain than in Brazil. Our results suggest that future interventions aiming at reducing Risky drinking may benefit from strategies targeting multiple domains of lifestyle.
