Ещё добавлю, что в период беременности мать переболела гриппом, может от этого и мой аппендицит.

Influenza
Among the in utero infections that are plausible risk factors for schizophrenia, influenza has been the most commonly examined. In a seminal study, Mednick et al.3 demonstrated an increase in risk of schizophrenia among Finnish individuals who were in the second trimester of fetal development during the 1957 A2 influenza pandemic; however, over 25 subsequent studies reported inconsistent findings,4 leading investigators to question the viability of the hypothesis.

Although these studies were groundbreaking, a significant limitation was the reliance on ecologic data to define influenza exposure, such that individuals were considered to have been influenza-exposed based only on having been in utero during one or more influenza epidemics. Since most were not influenza-exposed, this led to nondifferential misclassification of exposure, which may bias the effect toward the null. To address this limitation, we obtained serologic measures of antibody status in individual pregnancies to document influenza, then related the exposure to risk of schizophrenia in offspring using direct, research-based interviews.5 The sample was derived from the Prenatal Determinants of Schizophrenia Study based on a large and well-characterized birth cohort in northern California that was followed up for schizophrenia.6 We found that serologically documented influenza exposure during early to mid-gestation was associated with a 3-fold increased risk of schizophrenia; first trimester exposure to influenza conferred a 7-fold increased risk.5
