Depriving healthy subjects of sleep has been shown to acutely increase blood pressure and sympathetic nervous system activity. Prolonged short durations could lead hypertension through extended exposure raised 24-hour heart rate, elevated activity, increased salt retention. Such forces structural adaptations the entrainment cardiovascular operate at an equilibrium. Sleep disorders are associated with disease, but we not aware any published prospective population studies that have a link...
The coronavirus disease 2019 (COVID-19) pandemic is causing substantial morbidity and mortality, straining health care systems, shutting down economies, closing school districts. While it a priority to mitigate its immediate impact, we want call attention the pandemic's longer-term effect on children's health; COVID-19, via these closures, may exacerbate epidemic of childhood obesity increase disparities in risk. In many areas United States, COVID-19 has closed schools, some systems are not...
To explore the relationship between sleep duration and diabetes incidence over an 8- to 10-year follow-up period in data from First National Health Nutrition Examination Survey (NHANES I). We hypothesized that prolonged short is associated with obesity hypertension act as partial mediators of this relationship. The increased load on pancreas insulin resistance induced by chronically durations can, time, compromise beta-cell function lead type 2 diabetes. No plausible mechanism has been...
BackgroundDifferences in the neighborhood food environment may contribute to disparities obesity.ObjectivesThe purpose of this study was examine association environments with body mass index (BMI) and obesity after control for walkability.MethodsThis employed a cross-sectional, multilevel analysis BMI among 13,102 adult residents New York City. We constructed measures walkability neighborhood, defined as half-mile buffer around subject's home address.ResultsDensity BMI-healthy outlets...
Purpose. To examine whether urban form is associated with body size within a densely-settled city. Design. Cross-sectional analysis using multilevel modeling to relate mass index (BMI) built environment resources. Setting. Census tracts (n = 1989) the five boroughs of New York City. Subjects. Adult volunteers 13,102) from City recruited between January 2000 and December 2002. Measures. The dependent variable was objectively-measured BMI. Independent variables included land use mix; bus...
The prevalence of childhood asthma in the USA increased by 50% from 1980 to 2000, with especially high poor urban communities.Data on among children aged 4-5 years and hospitalisations for less than 15 old were available 42 health service catchment areas within New York City. Street tree counts provided City Department Parks Recreation. proximity pollution sources, sociodemographic characteristics population density each area also measured.Controlling potential confounders, an increase 1...
There are concerns that prenatal exposure to endocrine-disrupting chemicals increases children's risk of obesity. African-American and Hispanic children born in the Bronx or Northern Manhattan, New York (1998-2006), whose mothers underwent personal air monitoring for polycyclic aromatic hydrocarbon (PAH) during pregnancy, were followed up ages 5 (n = 422) 7 341) years. At age years, 21% obese, as 25% those After adjustment child's sex, at measurement, ethnicity, birth weight maternal receipt...
Urban landscape elements, particularly trees, have the potential to affect airflow, air quality, and production of aeroallergens. Several large-scale urban tree planting projects sought promote respiratory health, yet evidence linking cover human health is limited.We investigate association canopy with subsequent development childhood asthma, wheeze, rhinitis, allergic sensitization.Birth cohort study data were linked detailed geographic information systems characterizing 2001 coverage based...
To explore age differences in the relationship between sleep duration and mortality by conducting analyses stratified age. Both short long durations have been found to be associated with mortality. Short is negative health outcomes, but there little evidence that has adverse effects. No epidemiologic studies published multivariate age, even though life expectancy 75 years majority of deaths occur elderly. Multivariate longitudinal first National Health Nutrition Examination Survey using Cox...
A number of polycyclic aromatic hydrocarbons (PAH) are widespread environmental contaminants that cause mammary cancer experimentally. We investigated whether exposure and susceptibility to PAH, as measured by PAH-DNA adducts in breast tissue, associated with human cancer. carried out a hospital-based case-control study using immunohistochemical methods analyze tumor nontumor tissue from cases benign controls. The subjects were white, African-American Latina women without prior or treatment,...
ObjectiveTo characterize the influence of residential neighborhood older adults on prevalence disability.
Urban tree canopy is widely believed to have myriad environmental, social, and human-health benefits, but a lack of precise estimates has hindered quantification these benefits in many municipalities. This problem was addressed for New York City using object-based image analysis (OBIA) develop comprehensive land-cover map, including the scale individual trees. Mapping performed rule-based expert system that relied primarily on high-resolution LIDAR, specifically its capacity evaluating...
Little is known about the metabolic and heart rate responses to a typical hatha yoga session. The purposes of this study were 1) determine whether practice using various postures meets current recommendations for levels physical activity required improve maintain health cardiovascular fitness; 2) reliability costs across sessions; 3) compare those treadmill walking. In observational study, 20 intermediate-to-advanced level practitioners, age 31.4 ± 8.3 years, performed an exercise routine...
We sought to test whether the association between walkable environments and lower body mass index (BMI) was stronger within disadvantaged groups that may be particularly sensitive environmental constraints.We measured height weight in a diverse sample of 13 102 adults living throughout New York City from 2000-2002. Each participant's home address geocoded surrounded by circular buffer with 1-km radius. The composition built environment characteristics these areas were used predict BMI...
