Body-mass index (#BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity.. ..We show that, contrary to the dominant paradigm,… Continue reading Rising rural body-mass index is the main driver of the global #obesity epidemic in adults

#Injuries associated with electric-powered bikes and scooters: analysis of US consumer product data
..While persons injured using #E-bikes were more likely to suffer internal injuries (17.1%; 95% CI 5.6 to 28.6) and require hospital admission (OR=2.8, 95% CI 1.3 to 6.1), powered scooter injuries were nearly three times more likely to result in a diagnosis of concussion (3% of scooter injuries vs 0.5% of E-bike injuries). E-bike-related injuries were also… Continue reading #Injuries associated with electric-powered bikes and scooters: analysis of US consumer product data
Drinking Water #Salinity, Urinary Macro‐Mineral Excretions, and Blood #Pressure in the Southwest Coastal Population of Bangladesh
Sodium (Na+) in saline water may increase blood pressure (BP), but potassium (K+), calcium (Ca2+), and magnesium (Mg2+) may lower BP. We assessed the association between drinking water salinity and population BP.. ..fresh water (electrical conductivity, <0.7 mS/cm), mild salinity (electrical conductivity ≥0.7 and <2 mS/cm), and moderate salinity (electrical conductivity ≥2 and <10 mS/cm)..… Continue reading Drinking Water #Salinity, Urinary Macro‐Mineral Excretions, and Blood #Pressure in the Southwest Coastal Population of Bangladesh
Occupational #radiation exposure and excess additive risk of #cataract incidence in a cohort of US radiologic technologists
..There were 11 345 cataract diagnoses and 5440 of cataract surgery during 832 462 and 888 402 person-years of follow-up, respectively. Cumulative occupational radiation exposure was associated with self-reported cataract, but not with cataract surgery, with EAR/104 person-year Gy=94 (95% CI: 47 to 143, p<0.001) and EAR/104 person-year Gy=13 (95% CI: <0 to 57, p=0.551), respectively. There was… Continue reading Occupational #radiation exposure and excess additive risk of #cataract incidence in a cohort of US radiologic technologists
Association Between #Greenness Surrounding Schools and Kindergartens and Attention-Deficit/Hyperactivity Disorder in Children in China.
..The mean (SD) age of the 59 754 study participants was 10.3 (3.6) years, and 29 494 (49.4%) were girls. A total of 2566 participants (4.3%) had #ADHD symptoms. Greenness levels differed substantially across schools and kindergartens. The normalized difference vegetation index within 500 m of a school or kindergarten ranged from -0.09 to 0.77. Greater… Continue reading Association Between #Greenness Surrounding Schools and Kindergartens and Attention-Deficit/Hyperactivity Disorder in Children in China.
Birth #month, birth season, and overall and cardiovascular disease #mortality in US women: prospective cohort study
..In fully adjusted multivariable analyses, no significant association was observed between birth month, birth season, and overall mortality. Compared with women born in November, increased cardiovascular disease mortality was observed among those born from March to July (hazard ratio for March, 1.09, 95% confidence interval 0.98 to 1.21; April, 1.12, 1.00 to 1.24; May, 1.08,… Continue reading Birth #month, birth season, and overall and cardiovascular disease #mortality in US women: prospective cohort study
Association of Long-term Ambient #Ozone Exposure With Respiratory Morbidity in #Smokers
..In adjusted analysis, a 5-ppb (parts per billion) increase in ozone concentration was associated with a greater percentage of emphysema (β = 0.94; 95% CI, 0.25-1.64; P = .007) and percentage of air trapping (β = 1.60; 95% CI, 0.16-3.04; P = .03); worse scores for the mMRC Dyspnea Scale (β = 0.10; 95% CI, 0.03-0.17; P = .008), CAT (β = 0.65; 95% CI, 0.05-1.26; P = .04), and SGRQ… Continue reading Association of Long-term Ambient #Ozone Exposure With Respiratory Morbidity in #Smokers
#BPA: have flawed analytical techniques compromised risk assessments?
Experimental and epidemiological studies provide compelling evidence of a causal link between increasing exposure to endocrine-disrupting chemicals (environmental contaminants with the potential to perturb the development and function of the endocrine system) and increases in non-communicable diseases, including most aspects of metabolic syndrome.. ..By virtue of extensive research attention, bisphenol A (BPA) has become the… Continue reading #BPA: have flawed analytical techniques compromised risk assessments?
Precipitation and #Climate Zone Explains the Geographical Disparity in the Invasive #Cancer Incidence Rates in the United States
Environmental factors such as ultraviolet radiation and pollution have been known to influence the incidence rate of cancer. However, these factors do not explain the variation in incidence rates across the United States.. ..Precipitation and climate zone were included in each model along with demographic variables such as annual income, population by gender, race, and… Continue reading Precipitation and #Climate Zone Explains the Geographical Disparity in the Invasive #Cancer Incidence Rates in the United States
