<h3>Importance</h3> It is unclear to what extent the duration of screen time in infancy associated with subsequent diagnosis autism spectrum disorder. <h3>Objective</h3> To examine association between and development disorder at 3 years age. <h3>Design, Setting, Participants</h3> This cohort study analyzed data from mother-child dyads a large birth Japan. included children born women recruited January 2011 March 2014, were December 2020. The was conducted by Japan Environment Children's...
Previous studies have associated ambient particulate chemical constituents with adverse cardiopulmonary health effects. However, specific pollution sources behind the effects of particles are uncertain. We examined fine (PM2.5) from different in Beijing, China, among a panel 40 healthy university students. Study subjects were repeatedly for series indicators during three 2-month-long study periods (suburban period, urban period 1, and 2) 2010-2011 before after relocating suburban campus to...
Elevated blood pressure (BP) has been associated with particulate matter (PM) air pollution, but associations PM chemical constituents are still uncertain.We investigated of BP various fine (PM2.5) during 460 repeated visits among a panel 39 university students.Resting was measured using standardized methods before and after the students relocated from suburban campus to an urban different pollution contents in Beijing, China. Air data were obtained central monitors close student residences....
Abstract Background Ambient air pollution has been associated with activation of systemic inflammation and hypercoagulability increased plasma homocysteine, but the chemical constituents behind association are not well understood. We examined relations various fine particles (PM 2.5 ) biomarkers inflammation, coagulation homocysteine in context traffic-related pollution. Methods A panel 40 healthy college students underwent biweekly blood collection for 12 times before after their relocation...
Capturing epidemiological signatures is essential to document burdens of disease and design health care services, including prevention measures, clinical interventions, policies. There are large geographical ethnic variations in the epidemiology allergic immunological diseases. Various data available from North America Europe, but diseases Asia not well documented.
Nitrogen dioxide (NO(2)), an oxidant gas that contaminates both outdoor and indoor air, is considered to be a potential risk factor for asthma. We investigated concurrently the effects of NO(2) on prevalence incidence respiratory symptoms among children.A cohort study was carried out over 3 years 842 schoolchildren living in seven different communities Japan. Indoor concentrations 24 hours were measured winter summer homes subjects, 3-year average concentration determined each community....
This research aimed to examine the efficacy of early initiation breastfeeding within 1 h birth, skin-to-skin contact, and rooming-in for continuation exclusive until 6 months postpartum. The used data from Japan Environment Children's Study (JECS), a nationwide government-funded birth cohort study. A total 80,491 mothers in between January 2011 March 2014 who succeeded or failed exclusively breastfeed were surveyed JECS. Multiple logistic regression model was analyse data. percentage is...
The extremes of maternal pre-pregnancy body mass index (BMI) are known to be risk factors associated with obstetric and adverse perinatal outcomes. Among Japanese women aged 20 years or older, the prevalence underweight (BMI < 18.5 kg/m2) was 11.5% in 2019. Maternal thinness is a health problem caused by desire become slim. This study aimed investigate association between severity low BMI outcomes, including preterm birth (PTB), weight (LBW), small-for-gestational age (SGA).We conducted...
It is unclear whether increased television (TV) and DVD viewing in early childhood from age 1 year decreases development or poor increases TV/DVD viewing.
Abstract The association between maternal pre-pregnancy smoking status and asthma risk is unclear. This study aimed to investigate the pre- post-pregnancy bronchial at 3 years of age in a large birth cohort. Data 75,411 mother–child pairs from Japan Environment Children's Study (JECS) were analysed using multivariate logistic regression analysis. Overall, 7.2% children had asthma. before childbirth was as follows: Never = 60.0%, Quit recognising current pregnancy 24.1%, after finding out...
Automobile exhaust is considered to be a potential risk factor for respiratory diseases. To investigate the effects of traffic-related air pollution on symptoms among children who lived near trunk roads, we conducted cohort study 2,506 schoolchildren in eight different communities Japan. Over that four-year period, prevalence asthma was higher girls less than 50 m from roads (roadside areas) other areas studied. Testing trends showed increased significantly with increases concentration each...
Perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) have been shown to accumulate in the human body. The purpose of present study was examine factors associated with blood levels PFOS PFOA.A cross-sectional performed on 307 men 301 women (aged 16-76 years) living 15 prefectures Japan. Blood PFOA were measured by liquid chromatography-mass spectrometry. Hepatic enzymes (γ-GTP, GOT, GPT) ω-3 polyunsaturated fatty acids (DHA EPA) serum also measured. Associations between intake...
Ambient fine particulate matter (PM) has been associated with impaired lung function, but the effect of temperature on function and potential interaction between PM remain uncertain. To estimate short-term effects PM2.5 combined we measured daily peak expiratory flow (PEF) in a panel 37 healthy college students four different seasons. Meanwhile, also monitored concentrations indoor outdoor (particulate an aerodynamic diameter ≤2.5 μm), ambient relative humidity study area, where participants...
