Health Behavior Changes During COVID-19 Pandemic and Subsequent “Stay-at-Home” Orders

International Journal of Environmental Research and Public Health, Journal Year: 2020, Volume and Issue: 17(17), P. 6268 - 6268

Published: Aug. 28, 2020

The COVID-19 pandemic, and resultant “Stay-at-Home” orders, may have impacted adults’ positive health behaviors (sleep, physical activity) negative (alcohol consumption, drug use, tobacco use). purpose of this study was to investigate how these changed (increased/improved or decreased/worsened) at the early stages what participant characteristics were associated with behavior changes, why behavioral changes occurred. A convenience sample 1809 adults residing in United States completed a 15-min self-report questionnaire April May 2020. Multinomial logistic regressions descriptive statistics used evaluate how, for whom, changed. Participants primarily female (67.4%), aged 35–49 years (39.8%), college graduates (83.3%), non-tobacco users (74.7%), had previously marijuana (48.6%). Overall, participants reported decrease activity, while sleep all remained same. Changes related (p < 0.05) sex, age, parental status, educational job BMI, depression scores.

The objective of this systematic review was to examine the associations between sleep timing (e.g., bedtime/wake-up time, midpoint sleep), consistency/regularity intra-individual variability in duration, social jetlag, catch-up and health outcomes adults aged 18 years older. Four electronic databases were searched December 2018 for articles published previous 10 years. Fourteen examined. A total 41 articles, including 92 340 unique participants from 14 countries, met inclusion criteria. Sleep assessed objectively 37% studies subjectively 63% studies. Findings suggest that later greater generally associated with adverse outcomes. However, because most reported linear associations, it not possible identify thresholds “late timing” or “large variability”.

Sleep is an important contributor to physical and mental health; however, chronic sleep deprivation has become common in adolescents, especially on weekdays. Adolescents aged 14-17 years are recommended between 8 10 h per night maximize overall health well-being. Although needs may vary individuals, duration recommendations for surveillance help inform policies, interventions, the population of healthy behaviors. Long sleepers very rare among teenagers sleeping too much not a problem se; only insufficient associated with adverse outcomes pediatric population.

Abstract The “International Biomarkers Workshop on Wearables in Sleep and Circadian Science” was held at the 2018 SLEEP Meeting of Associated Professional Societies. workshop brought together experts consumer sleep technologies medical devices, circadian physiology, clinical translational research, practice. goals were: (1) characterize term “wearable” for use science identify relevant metrics wearables to measure; (2) assess current science; (3) barriers applying (4) opportunities advance science. For purposes biomarker development fields, included terms “wearables,” “nearables,” “ingestibles.” Given state technology, limited validation wearable devices against gold standard measurements is primary factor limiting large-scale research. As such, committee proposed a set best practices studies guidelines regarding how choose device research use. To complement studies, recommends public data repository data. Finally, scientists must actively engage maintain rigor scientific findings health messages based technology.

Background: We aimed to assess the association of sleep with metabolic syndrome in 2013/2014 National Health and Nutrition Examination Survey (NHANES). Methods: Sample size included 2737 out 2013 2014 NHANES surveys. Cross-sectional study duration was conducted. Metabolic defined according NCEP ATPIII (National Cholesterol Education Program Adult Treatment Panel III) criteria. severity score calculated based on actual measurement each component, adjusted for sex race. The generalized additive model (GAM) built smooth relationship between syndrome/metabolic duration. Adjustment models were done age, sex, race, sitting time. value effective degree freedom (EDF) formed by GAM shows curvature relationship. A 1 EDF is translated as linear shape Values larger than one denote a more complex response variable predicting one. Results: There U-shaped univariable (EDF = 2.43, p 0.06) multivariable 2.03, 0.20). lowest risk observed people sleeping 7 hours/night. significant 2.94, 0.0004).

Working Time Society consensus statements: Evidence-based effects of shift work on physical and mental health

Industrial Health, Journal Year: 2019, Volume and Issue: 57(2), P. 139 - 157

Published: Jan. 1, 2019

Potential effects of shift work on health are probably related to the misalignment between light-dark cycle and human activity-rest cycle. Light exposure at night mediates these effects, including social leads an inversion activity rest, which, in turn, is linked changes behaviours. This article reviews epidemiological evidence association health, possible mechanisms underlying this association. First, from findings meta-analyses systematic published last 10 yr presented. In addition, it reports larger single-occupation studies recent large population-based general workforce. Koch's postulates were used evaluate development disease as a result work. Finally, we discussed limitations multiple pathways that link with specific disorders methodological challenges facing research. We concluded clearest indications being cause given when there substantial body high quality field showing good laboratory supporting causal explanation link.
