Summary Using a cross‐sectional probability sample with actigraphy data and two 24‐h dietary recalls, we quantified the association between sleep duration, continuity, variability timing Alternative Healthy Eating Index‐2010 diet quality score its components in 2140 Hispanic Community Health Study/Study of Latinos participants.

To examine the effects of moderate sleep restriction (SR) on body weight, composition, and metabolic variables in individuals undergoing caloric (CR). Overweight or obese adults were randomized to an 8 week (CR) regimen alone (n = 15) combined with (CR + SR) 21). All participants instructed restrict daily calorie intake 95 per cent their measured resting rate. Participants CR SR group also reduce time bed five nights ad libitum other two each week.

Cross-sectional and prospective associations between sleep regularity and metabolic health in the Hispanic Community Health Study/Study of Latinos

SLEEP, Год журнала: 2020, Номер 44(4)

Опубликована: Окт. 23, 2020

Abstract Study Objectives Sleep is an emergent, multi-dimensional risk factor for diabetes. duration, timing, quality, and insomnia have been associated with diabetes glycemic biomarkers, but the role of sleep regularity in development metabolic disorders less clear. Methods We analyzed data from 2107 adults, aged 19–64 years, Sueño ancillary study Hispanic Community Health Study/Study Latinos, followed over a mean 5.7 years. Multivariable-adjusted complex survey regression methods were used to model cross-sectional prospective associations between index (SRI) quartiles (Q1-least regular, Q4-most regular) (either laboratory-confirmed or self-reported antidiabetic medication use), baseline levels insulin resistance (HOMA-IR), beta-cell function (HOMA-β), hemoglobin A1c (HbA1c), their changes time. Results Cross-sectionally, lower SRI was higher odds (odds ratio [OR]Q1 vs. Q4 = 1.64, 95% CI: 0.98–2.74, ORQ2 1.12, 0.70–1.81, ORQ3 1.00, 0.62–1.62, ptrend 0.023). The effect more pronounced older (aged ≥ 45 years) adults (ORQ1 1.88, 1.14–3.12, pinteraction 0.060) compared younger ones. No statistically significant found incidence, as well HOMA-IR, HOMA-β, HbA1c values, time among not taking medication. Conclusions Our results suggest that represents another dimension relevant risk. Further research needed elucidate relative contribution dysregulation pathophysiology.

Do sleep and circadian characteristics predict alcohol use in adult drinkers?

Alcohol Clinical and Experimental Research, Год журнала: 2024, Номер 48(4), С. 680 - 691

Abstract Background While sleep and circadian rhythms are recognized contributors to the risk for alcohol use related problems, few studies have examined whether objective measures can predict future in humans, no such been conducted adults. This study any baseline and/or characteristics of otherwise healthy adults predicted their over subsequent 12 months. Methods Participants (21–42 years) included 28 light 50 heavy drinkers. At baseline, a comprehensive range self‐reported sleep/circadian was assessed via questionnaires, wrist actigraphy, measurement dim melatonin onset photoreceptor responsivity. Following this, number alcoholic drinks per week binge drinking episodes month were quarterly Anticipated effects (stimulation, sedation, rewarding aspects) also Analyses generalized linear mixed‐effects models causal mediation analysis. Results Across measures, only insomnia symptoms longer total time at more binges ( p s <0.02). There trend anticipated effect wanting 6‐month timepoint mediate relationship between months = 0.069). Conclusions These results suggest that adults, symptoms, even if subclinical, significant predictor drinking, appear outweigh influence factors on least Insomnia may be modifiable target reducing misuse.
