Emerging but limited evidence suggests that alcohol consumption has increased during the COVID-19 pandemic. This study assessed: (1) whether drinking behaviors changed pandemic; and, (2) how those changes were impacted by COVID-19-related stress. We conducted a cross-sectional online survey with convenience sample of U.S. adults over 21 years in May 2020. adjusted linear regressions to assess stress and consumption, adjusting for gender, race, ethnicity, age, household income. A total 832...
The response to the COVID-19 pandemic became increasingly politicized in U.S., and political affiliation of state leaders may contribute policies affecting spread disease. This study examines differences infection, death, testing by governor party across 50 U.S. states District Columbia.A longitudinal analysis was conducted December 2020 examining incidence, testing, test positivity rates from March 15, through 2020. A Bayesian negative binomial model fit estimate daily risk ratios posterior...
Abstract Background Early introduction of complementary foods has been associated with various immune disorders, oxidative stress, and obesity in childhood. The gut microbiota the short chain fatty acids (SCFAs) they produce are postulated to be on causal pathway. objective this study was determine if early feeding (i.e. consumption solids or non-water/formula liquids at before 3 months) is prospectively infant composition, diversity SCFAs 12 months age Nurture birth cohort. Results...
Socially vulnerable communities may be at higher risk for COVID-19 outbreaks in the US. However, no prior studies examined temporal trends and differential effects of social vulnerability on incidence death rates. Therefore, we among counties with high low to quantify disparities over time.We conducted a longitudinal analysis examining rates from March 15 December 31, 2020, each US county using data USAFacts. We classified Social Vulnerability Index (SVI), percentile-based measure Centers...
The Baby-Friendly Hospital Initiative (BFHI) designation is known to increase breast-feeding rates in the USA. However, less about barriers and facilitators support practices BFHI hospitals how they differ from non-BFHI hospitals. We examined what are perceived affect among hospital administrators further explored factors that presented challenges adoption continuation of practices. Cross-sectional study was conducted. measured whether were implementing 12 identified survey questionnaire...
Epigenetic mechanisms are proposed to link maternal concentrations of methyl group donor nutrients with the risk low birth weight. However, empirical data lacking. We have examined association between folate and weight assessed mediating role DNA methylation at nine differentially methylated regions (DMRs) genomically imprinted genes in these associations. Compared newborns women levels lowest quartile, was higher mothers second (β = 143.2, se 63.2, P 0.02), third 117.3, 64.0, 0.07), fourth...
In the United States (US), recreational cannabis use is on rise. Since 2011, 11 states and District of Columbia have legalized for adult use. As additional consider legalizing, there an urgent need to assess associations between legalization maternal in preconception, prenatal, postpartum periods-all critical windows child health. Using cross-sectional data from 2016 Pregnancy Risk Assessment Monitoring System, we assessed state self-reported logistic regression, estimated adjusted...
Prenatal antibiotic exposure has been associated with an altered infant gut microbiome composition and higher risk of childhood obesity, but no studies have examined if prenatal antibiotics simultaneously alter the adiposity in infants. In this prospective study (Nurture: recruitment 2013–2015 North Carolina, United States), we 454 infants association (by any exposure; by trimester pregnancy; number courses; type antibiotics) age- sex-specific weight-for-length z score (WFL-z) skinfold...
<h3>Importance</h3> Recent studies have revealed increases in population-level cannabis use after legalization of recreational cannabis. However, the association with maternal during important life stages remains unknown. <h3>Objective</h3> To investigate preconception, prenatal, and postpartum periods. <h3>Design, Setting, Participants</h3> This repeated cross-sectional study used state-level data on women who delivered live-born infants US from Pregnancy Risk Assessment Monitoring System...
Physical activity in pregnancy and postpartum is beneficial to mothers infants. To advance knowledge of objective physical measurement during these periods, this study compares hip wrist accelerometer compliance; assesses convergent validity (correlation) between hip- wrist-worn accelerometry; change from postpartum.
Background: Alcohol consumption in the U.S. is a public health problem that has been exacerbated by COVID-19 pandemic. Relatedly, many states have responded to relaxing their alcohol laws, making it possible for adults delivered homes. This study sought understand impact of allowing home delivery on self-reported adult US. Methods: In May 2020, we surveyed convenience sample over 21 years age recruited through social media and listservs. Eight hundred thirty-two participants completed online...
Abstract Background Early care and education (ECE) is an important setting for influencing young children’s dietary intake. There are several factors associated with barriers to healthy eating in ECE, recent evidence suggests that participation the Child Adult Care Food Program (CACFP), primary national food assistance program may be fewer serving healthier foods. However, no prior studies have examined differences between CACFP participants non-participants across a large, multi-state...
Numerous previous studies have reported positive associations between exposure to greenspace and children's physical activity, but in high-income countries only. Prior also examined obesity children, these yielded inconsistent results focused mostly on older children. The purpose of this study was assess time children spent as the primary our outcomes interest, including 1) minutes 2) body mass index (BMI) z-score. Our sample 102 ages 3 5 years living Ensenada Tijuana, Mexico. We fit linear...
Abstract Small Island Developing States (SIDS) share high burdens of nutrition-related conditions, including non-communicable diseases, associated with an increasing reliance on imported, processed foods. Improving health through the production and consumption local, nutritious foods is a policy objective many SIDS governments. This study aimed to understand contemporary challenges opportunities strengthening local food systems in two case settings, Fiji St. Vincent Grenadines. Fifty-two...
Cannabis use in the United States has been steadily increasing. Much more is known about cannabis users states where recreational legal, compared to yet legalize.
