Prevalence of autism diagnosis has historically differed by demographic factors. Using data from 8224 participants drawn from the Environmental influences on Child Health Outcomes (ECHO) Program, we examined relationships between demographic factors and parent-reported autism-related traits as captured by the Social Responsiveness Scale (SRS; T score > 65) and compared these to relations with parent-reported clinician diagnosis of ASD, in generalized linear mixed effects regression analyses. Results suggested lower odds of autism diagnosis, but not of SRS T > 65, for non-Hispanic Black children (adjusted odds ratio [OR] = 0.

- The study aimed to assess the exposure levels of the Lassa virus (LASV) in two urban areas of Nigeria to inform preventive measures against Lassa fever outbreaks.* -
- Conducted from February to July 2022, the research involved collecting and analyzing serum samples from 628 participants in Abuja and Lagos for LASV antibodies while gathering sociodemographic data through questionnaires.* -
- Results showed a 27% overall seroprevalence of LASV antibodies, with higher rates in Abuja (33%) compared to Lagos (18%), and identified factors like the dry season, inconsistent washing of produce, and positive malaria tests as linked to higher seropositivity in Abuja.*
Predicting blood lead in Uruguayan children: Individual- vs neighborhood-level ensemble learners.
PLOS Glob Public Health
September 2024
Predicting childhood blood lead levels (BLLs) has had mixed success, and it is unclear if individual- or neighborhood-level variables are most predictive. An ensemble machine learning (ML) approach to identify the most relevant predictors of BLL ≥2μg/dL in urban children was implemented. A cross-sectional sample of 603 children (~7 years of age) recruited between 2009-2019 from Montevideo, Uruguay participated in the study.

These social mechanisms may modify the effects of air pollution on dementia risk. This cohort study examines the potential moderating effect of social cohesion on associations between joint air pollution exposure and incident dementia leveraging data from 5112 community-dwelling adults ≥65 years of age enrolled in the National Health and Aging Trends Study (NHATS).

Methods: We leveraged a cohort of adults ≥65 years (n = 5397) enrolled from 2011 to 2018 in the National Health and Aging Trends Study (NHATS).
