Physical activity (PA) during COVID-19 shelter-in-place (SIP) may offset stress. This study examined associations between PA, stress and management strategies SIP.Participants (N = 990) from a cohort of Northern California adults completed surveys early SIP (3/23/20-4/2/20) mid-SIP (4/24/20-5/8/20). Participants self-reported past-month PA (meeting vs. not meeting guidelines), changes in (decreased/unchanged increased) use (yes/no) 10 strategies. We tested differences by strategies.Compared...

Abstract Background The emergence of COVID-19 in Canada prompted extensive efforts population-wide surveillance, including wastewater-based surveillance (WBS). WBS offers insights into the prevalence infectious disease burden, however, reasons for poor correlation between hospital admissions and wastewater viral signal some locations across Ontario remain unclear, while others demonstrate remarkable correlations. This study aims to elucidate parameters influencing hospitalization-WBS quality...

The emergence of COVID-19 in Canada has led to over 4.9 million cases and 59,000 deaths by May 2024. Traditional clinical surveillance metrics (hospital admissions laboratory-positive cases) were complemented with wastewater environmental monitoring (WEM) monitor SARS-CoV-2 incidence. However, challenges public health integration WEM persist due perceived limitations data quality, potentially driving inconsistent correlations variability lead times. This study investigates how factors like...

Monitoring of viral signal in wastewater is considered a useful tool for monitoring the burden COVID-19, especially during times limited availability testing. Studies have shown that COVID-19 hospitalizations are highly correlated with signals and increases can provide an early warning increasing hospital admissions. The association likely nonlinear time-varying. This project employs distributed lag model (DLNM) (Gasparrini et al., 2010) to study exposure-response delayed SARS-CoV-2 using...

Psychosocial health can influence the development and experience of several chronic diseases, has been negatively affected for many individuals amid COVID-19 global pandemic. To understand impact contemplative practices on emotional mental during COVID-19, Stanford WELL Life Study (US component), incorporated a series additional surveys into its ongoing study. A total 1,097 participants residing in California who responded to at least one three were included this analysis. Linear generalized...

Abstract The quality of one's overall diet has proven to be great importance health and well‐being. Unfortunately, is time‐consuming assess. Stanford Wellness Living Laboratory (WELL) administered an online survey that included the WELL Diet Score (a novel assessment calculated from 12 diet‐related items). Subsequently, participants were asked complete 127‐item Block Food Frequency Questionnaire (FFQ) online. present study's primary objective was compare with established FFQ‐based...

Viral signal in wastewater offers a promising opportunity to assess and predict the burden of infectious diseases. That has driven widespread adoption development monitoring tools by public health organizations. Recent research highlights strong correlation between COVID-19 hospitalizations viral signals, validates that increases measurements may offer early warnings an increase hospital admissions. Previous studies (e.g. Peng et al. 2023) utilize distributed lag models explore associations...

Background: Psychological resilience (resilience), defined as the self-reported ability to bounce back from stress, has been associated with diet quality. Despite importance of successful aging, few studies have examined relationship between and quality across different age groups. Objective: To examine while adjusting for perceived sociodemographic information, other diet-related health factors within youngest, middle-aged, oldest groups in Well Life (WELL) study. Design: Cross-sectional...
