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.

Supplemental nutrition assistance program 2009 expansion and cardiometabolic markers among low-income adults.
A 2009 Supplemental Nutrition Assistance Program (SNAP) policy change that expanded eligibility and increased benefit amounts has been associated with reduced food insecurity. This study tests the hypothesis that the SNAP policy change corresponds with improved stress- and nutrition-sensitive cardiometabolic markers. This study included non-pregnant participants aged 18-59 with annual family incomes ≤185% of the federal poverty guideline from the repeated cross-sectional NHANES study. ⋯ This study found less of an upward trend in hemoglobin A1c levels for young and middle aged adults and decreased total cholesterol for young adults. These results highlight the potential role of SNAP to prevent costly chronic conditions among low-income U. S. adults.

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).

Associations between neighbourhood built characteristics and sedentary behaviours among Canadian men and women: findings from Alberta's Tomorrow Project.
Evidence of associations between neighbourhood built characteristics and sedentary behaviours is mixed. The study aim was to investigate the associations between objectively-derived neighbourhood built characteristics and self-reported sedentary behaviours among Canadian men and women. This study sourced survey data from Alberta's Tomorrow Project (2008; n = 14,785), in which sitting and motor vehicle travel times during the last 7 days was measured. ⋯ Among women, Normalized Difference Vegetation Index was negatively associated with sitting time. Interventions to reduce sedentary behaviours may need to target neighbourhoods that have built characteristics which might support these behaviours. More research is needed to disentangle the complex relationships between different neighbourhood built characteristics and specific types of sedentary behaviour.
