An ecological study on childhood autism
BACKGROUND AND METHODS Idiopathic autism, suspected to be caused by exposure of genetically susceptible individuals to unknown environmental triggers, has increased dramatically in the past 25 years. The objectives of our study were to determine, using a linear regression model, whether the county prevalence of autism in the Pacific Northwest of the United States was associated with the source ...
متن کاملTemperature variability and childhood pneumonia: an ecological study
BACKGROUND Few data on the relationship between temperature variability and childhood pneumonia are available. This study attempted to fill this knowledge gap. METHODS A quasi-Poisson generalized linear regression model combined with a distributed lag non-linear model was used to quantify the impacts of diurnal temperature range (DTR) and temperature change between two neighbouring days (TCN)...
متن کاملAn epidemiological study on Japanese autism concerning routine childhood immunization history.
To assess the causal association of autism with measles, mumps, and rubella (MMR) vaccine versus that with monovalent measles, mumps, and rubella immunization, a 1:2 sex-adjusted logistic regression analysis was conducted using data on subjects who were growing up in the Tokyo area between 1988 and 1992. When MMR immunization was used as a reference, monovalent measles immunization (odds ratio ...
متن کاملDesigning an Ecological Study
Ecology can be defined as the study of ecological systems. A system is any set of components, living or nonliving, that are tied together by regular interactions. An ecological system is made up of one or more organisms, together with the nonliving environment with which they interact. Ecological systems exist at several different levels of organization. An ecological system can be a single org...
متن کاملPrenatal and perinatal analgesic exposure and autism: an ecological link
BACKGROUND Autism and Autism Spectrum Disorder (ASD) are complex neurodevelopmental disorders. Susceptibility is believed to be the interaction of genetic heritability and environmental factors. The synchronous rises in autism/ASD prevalence and paracetamol (acetaminophen) use, as well as biologic plausibility have led to the hypothesis that paracetamol exposure may increase autism/ASD risk. ...
