Sibship characteristics during upbringing and schizophrenia risk.
The potential association between sibship characteristics and the risk of schizophrenia has been investigated previously. However, methods have differed and results have been conflicting. The authors explored the association between birth order, sibship size, and birth interval to siblings and schizophrenia while accounting for potential confounders. Using Danish Civil Registration System data,...
متن کاملEvidence of a dose-response relationship between urbanicity during upbringing and schizophrenia risk.
BACKGROUND Many studies have demonstrated that an urban birth or upbringing increases schizophrenia risk, but no studies have been able to distinguish between these effects. The objectives of this study were to discriminate the effect of urbanicity at birth from an effect of urbanicity during upbringing, and to identify particularly vulnerable age periods and a possible dose-response relationsh...
متن کاملSibship characteristics and risk of allergic rhinitis and asthma.
Studying associations between sibship characteristics and allergic diseases in detail may contribute clues to their etiology. The authors studied associations between sibship characteristics and risk of self-reported allergic rhinitis and asthma among 31,145 pregnant women participating in a nationwide study in Denmark during 1997-2000. Increasing sibship size was associated with a decreased ri...
متن کاملBrain structure correlates of urban upbringing, an environmental risk factor for schizophrenia.
Urban upbringing has consistently been associated with schizophrenia, but which specific environmental exposures are reflected by this epidemiological observation and how they impact the developing brain to increase risk is largely unknown. On the basis of prior observations of abnormal functional brain processing of social stress in urban-born humans and preclinical evidence for enduring struc...
متن کاملSibship characteristics and risk of multiple sclerosis: a nationwide cohort study in Denmark.
It has been hypothesized that age at infection with a common microbial agent may be associated with the risk of multiple sclerosis (MS). The authors addressed this hypothesis by using number of older siblings and other sibship characteristics as an approximation of age at exposure to common infections. Data on family characteristics and vital status from the Danish Civil Registration System wer...
