Published: March 27, 2025

Importance Electronic screen use before bed may disrupt circadian rhythms, leading to poorer sleep. Objective To investigate the association between and sleep outcomes among adults. Design, Setting, Participants This cross-sectional study included participants in American Cancer Society Prevention Study–3, a prospective cohort of men women from 35 US states Puerto Rico, who responded 2018 survey. Analyses were conducted February 3, 2023, January 10, 2025. Exposures Self-reported electronic hour prior bed. Main Outcomes Measures sleep-wake times (used calculate duration), quality, chronotype. Mean differences for duration bedtimes, prevalence ratios quality calculated by using multivariable linear Poisson regression, respectively. Whether these associations differed chronotype was also examined. Results Of 122 058 (97 658 [80.0%]; median [IQR] age, 56 [47-62] years; range, 27-85 years), 70 638 (57.9%) reported morning Daily 50 289 (41.2%), whereas 21 275 (17.4%) no use. Compared with use, daily associated 33% higher poor (prevalence ratio, 1.33; 95% CI, 1.27-1.39) 7.64 fewer minutes on workdays (95% 6.65-8.63 minutes). The more pronounced evening chronotypes (8.36 minutes; 4.94-11.78 minutes) vs those (5.64 3.98-7.29 5.04 4.03-6.05 nonworkdays. users went 9.33 later 7.61-11.06 minutes), 15.62 11.93-19.31 workdays. similar Conclusions Relevance bedtimes approximately less each week. Associations greater chronotypes, are at risk due social jetlag (ie, misalignment rhythms commitments). These findings confirm disruptions screens not limited children adolescents.

Objective The aim of this meta-analysis is to evaluate the impact light at night (LAN) exposure on risk breast cancer across varying factors. Method We conducted a systematic search literature up July 15, 2023, including PubMed, Cochrane Library, and Embase databases, using keywords related LAN exposure. Cohort study case–control were included. Statistical analyses performed Stata software version 17.0. To address heterogeneity among different studies, we employed random-effects model for analysis assessed publication bias funnel plots Egger’s test. Results included 13 8 cohort studies with 734,372 participants worldwide. In Newcastle-Ottawa Scale (NOS) assessments, average score was 7.43 (ranging from 5 9). overall demonstrated significant association between (RR = 1.12; 95% CI: 1.06–1.17; I 2 31.3%, p < 0.001). subgroup analysis, results types (case–control studies: RR 1.16; 1.06–1.27; 40.4%, 0.001; 1.08; 1.04–1.14; 0.0%, 0.001) (outdoor LAN: 1.07; 1.02–1.13; 30.9%, 0.004) are presented. continents, highest observed in Asian population (Asian: 1.24; 1.15–1.34; estrogen receptor status (ER+: 1.10; 1.03–1.18; 17.0%, 0.005;). also an menopausal various lifestyles but did not find any statistically findings.

Chlordane exposure impairs the growth and behavior of Drosophila

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 270, P. 115903 - 115903

Published: Jan. 1, 2024

Chlordane, a previously extensively utilized insecticidal pesticide, has since been prohibited, however, owing to its limited degradability, it continues persist significantly in soil and water reservoirs, subsequently accumulating within plant animal organisms, representing substantial threat human health. Despite extensive research conducted over the past few decades investigate toxic effects of chlordane, there remains notable dearth studies focusing on impact sleep activity. Therefore, this study, short-term long-term exposure chlordane activity Drosophila were investigated. When exposed at concentration 1 μM, lost body weight, decreased size resulted lipid metabolism disorders. In addition, altered arousal behaviors Drosophila. Short-term an increase night-time duration, while decrease sleep, as evidenced by duration each session appearance fragmentation. Under conditions exposure, reactive oxygen species levels up-regulated Our results suggest that triggers oxidative stress damage Drosophila, leading disruption. This study offers novel insights into harmful impacts environmental pollutants patterns proposes mitigating presence environment could potentially contribute reduction global disorder prevalence.

The widespread and pervasive use of artificial light at night (ALAN) in our modern 24-hour society has emerged as a substantial disruptor natural circadian rhythms, potentially leading to rise unhealthy lifestyle-related behaviors (e.g., poor sleep; shift work). This phenomenon been associated with an increased risk type 2 diabetes mellitus (T2DM), which is pressing global public health concern. However, date, reviews summarizing associations between ALAN T2DM have primarily focused on the limited characteristics exposure intensity) ALAN. literature review extends beyond prior by consolidating recent studies from 2000 2024 regarding both indoor outdoor incidence or prevalence T2DM. We also described potential biological mechanisms through modulates glucose metabolism. Furthermore, we outlined knowledge gaps investigated how various only intensity (including type, timing, duration, wavelength, individual sensitivity) influence risk. Recognizing detrimental impact sleep behavioral correlates physical activity dietary patterns, additionally summarized investigating mediating role each component relationship Lastly, proposed implications chronotherapies chrononutrition for management context exposure.

Summary Light exposure affects the circadian system and consequently can affect sleep quality. Only few studies examined this relationship in children. We evaluated associations between light patterns metrics measured parameters of 247 Dutch children, aged 11 13 years recruited from ABCD cohort, using actigraphy records for 7 consecutive nights. Personal exposures were with a meter during whole day night. applied generalized mixed‐effects regression models, adjusted possible confounders, to evaluate on duration, efficiency sleep‐onset delay. In models mutually potential we found amount hours first time bright morning going duration be significantly associated decreased (in min; β: −2.02 [95% confidence interval: −3.84, −0.25], −8.39 −16.70, −0.07], respectively) shorter delay (odds ratio: 0.88 0.80, 0.97], odds 0.40 0.19, 0.87], respectively). Increased intensities at night (T2 −8.54 −16.88, −0.20], T3 −14.83 −28.04, −1.62]), while increased before bed prolonged onset 4.02 2.09, 7.73]).
