Longitudinal measures of phthalate exposure and asthma exacerbation in a rural agricultural cohort of Latino children in Yakima Valley, Washington
This study used data from the Home Air in Agriculture Pediatric Intervention Trial (HAPI) to examine relationships between phthalate exposure and outcomes related to childhood asthma exacerbation. We used measures of phthalate metabolites and respiratory health measures including fractional exhaled nitric oxide (FENO), the Asthma Control Test (ACT), caregiver report of symptoms, and urinary leukotriene E4 (uLTE4) to estimate longitudinal associations using mixed effects models, adjusted for covariates. For 100% (i.e., doubling) increases in mono-(2-ethyl-5-carboxypentyl) phthalate (MECPP), mono-2-ethylhexyl phthalate (MEHP...

Exposure variability and determining factors of urinary metals for schoolchildren in Taiwan
This study assessed metal concentrations and variability in the urine of schoolchildren and explored their important determining factors. We collected spot urine samples from schoolchildren (n = 321) living in urban, suburban, and rural areas during the warm and cold seasons. The toxic (As, Cd, Ni, Cd, and Pb) and essential (Co, Cu, Mo, and V) elements of urine samples were analyzed by inductively coupled plasma mass spectrometry. We assessed the within- and between-subject variability in urinary metal concentrations, calculated the "probability of overexposure (θ)," compared with the reference values. We evaluated the sp...

Polybrominated diphenyl ethers in early pregnancy and preterm birth: Findings from the NICHD Fetal Growth Studies
CONCLUSIONS: PBDEs, specifically PBDE 153, were associated with shorter gestation and higher risk of certain PTB subtypes among pregnant women without obesity.PMID:35569252 | DOI:10.1016/j.ijheh.2022.113978 (Source: International Journal of Hygiene and Environmental health)

Attributable risk of household solid fuel use and second-hand smoke associated with under-5 mortality in 46 low- and lower-middle-income countries, 2010-2020
This study provides a comprehensive assessment of their odds ratios and attributable mortality in LMICs.METHODS: We used the Demographic Health Surveys data for under-5 children in 46 LMICs (n = 778,532) from 2010 to 2020. Mixed effect multilevel logistic regressions were conducted to estimate the pooled adjusted odds ratio (aOR) for U5M due to solid fuel use, SHS and their combination compared to no exposure to them in 46 LMICs. The attributable mortality of solid fuel use, SHS, and their combination were assessed for each LMIC.FINDINGS: The pooled aOR of solid fuel use and SHS for U5M was estimated to be 1.27 (95% Confid...

Urinary phthalate metabolite concentrations during four windows spanning puberty (prepuberty through sexual maturity) and association with semen quality among young Russian men
CONCLUSIONS: ∑DiNP metabolites measured during late puberty and MiBP metabolites at early puberty were related to poorer semen quality, highlighting the importance of considering specific windows of exposure when investigating chemical exposures in relation to measures of reproductive health in men.PMID:35533529 | DOI:10.1016/j.ijheh.2022.113977 (Source: International Journal of Hygiene and Environmental health)

Home gardens and distances to nature associated with behavior problems in alpine schoolchildren: Role of secondhand smoke exposure and biomarkers
CONCLUSIONS: Natural environments in school and home surroundings might be beneficial for school conduct and performance. Lower secondhand smoke exposure at home might be a pathway between home gardens and children's behavioral problems. Associations with residential proximity to nature in this study were in unexpected directions and warrant further investigation. These findings serve as a point of departure for investigating how proximal nature might activate health supportive pathways in children and simultaneously confer childhood health benefits via positive behavioral changes in their parents.PMID:35526418 | DOI:10.10...
