The ESTxENDS Trial- Effects of Using Electronic Nicotine Delivery Systems (ENDS/Vaporizer/E-cig) on Sleep Quality.

Cigarette smoking is the leading cause of preventable death in Switzerland and still more than a quarter of the Swiss population smokes cigarettes. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. The majority of attempts to quit tobacco smoking do not end in success due to unpleasant withdrawal symptoms. One of such symptoms is disturbed sleep. Sleep disturbances are a problem for smokers who are trying to quit. Sleep disturbances results from difficulty falling asleep or frequent arousals after sleep onset, and have negative daytime consequences such as sleepiness and dysphoric mood. Studies indicate that awakenings during night affect the cardiovascular system by providing repetitive bursts of sympathetic nervous system activation, likely contributing to elevated levels of cardiovascular and cerebrovascular morbidity. ENDS with nicotine containing e-liquids may be effective in assisting with tobacco smoking cessation by reducing withdrawal-induced sleep disturbances. This study will therefore test the efficacy of ENDS for cigarette smoking cessation, the safety of ENDS on adverse events and the effect of ENDS on health-related outcomes and exposure to inhaled chemicals. For this trial, cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-month period. Sleep quality will be assessed using the Pittsburgh sleep quality index- questionnaire at baseline and at 6, 12 and 24 months' follow-up.

Changing School Start Times: Impact on Student, Family, Teacher, and Community Health

Sleep is not an optional luxury, but a fundamental biological need, essential for health and well-being. Insufficient sleep is a significant public health issue, with 69% of adolescents in America obtaining less than the minimum requirement of 8 hours of sleep per night. Early school start times has been identified as the most significant and modifiable factor that restricts sleep duration in adolescents. The American Academy of Pediatrics recommended in 2014 that all middle and high schools start no earlier than 8:30 a.m., yet few school districts have implemented this change. In fall 2017, the Cherry Creek School District, a diverse district of almost 55,000 students outside Denver, changed school start times. Although previous studies have shown increased sleep duration, decreased daytime sleepiness, and improved academics following start time changes for secondary students, there remains an urgent need to understand how this policy impacts health and well-being for all students, including youth in elementary school. Recognizing that students are part of a complex system that includes parents, school staff, and the community, this observational study will be a multi-year, broad-based evaluation that includes key stakeholders, multiple sources of quantitative data (i.e., surveys, academic records, district nursing electronic health records), contextual qualitative data (i.e., open-ended surveys and focus groups), and community-based outcomes (i.e., data on vehicle crashes and juvenile crimes). The primary hypothesis is that later school start times will have a positive impact on middle and high school students sleep and health outcomes, while earlier school start times will have a neutral impact on elementary school students sleep and health outcomes.
