On the basis of previous findings, we used meta-analyses to consider whether births to parents with schizophrenia have an increased risk of obstetric complications. Meta-analyses were based on published studies satisfying the following selection criteria. The schizophrenic diagnosis could apply to either parent: parents with non-schizophrenic psychoses were not included: ...

Compared to the general population, one consistent finding in schizophrenia research is a significant surplus of schizophrenic births in the winter/spring months. There is little evidence that this is attributed to statistical artefacts. The "harmful effects' hypothesis offers the most plausible explanation for this phenomenon. Exogenous harmful effects, predominant during ...

Biological rhythms play a prominent role in the human life cycle. The endogenous rhythms are entrained by the environment and have an astronomical counterpart which is obvious for daily, monthly, and yearly rhythms, and may possibly also be present in weekly rhythms. Circadian rhythms are present in, e.g. testosterone levels, ...

BACKGROUND: The season of birth phenomenon in schizophrenia was reexamined in relation to place of birth, in order to test the hypothesis that a seasonal factor might operate preferentially among those who were urban-born. METHOD: The seasonal distribution of births was examined among 3253 patients in two case registers having ...
Schnur D B - - 1995
Schizophrenia is said to be associated with a modest excess of winter births. We examined relations of season of birth (SOB) to the skin conductance response (SCR) and finger pulse amplitude response (FPAR) components of the orienting response (OR) in 83 schizophrenic patients, 59 depressed patients, and 81 normal controls. ...

OBJECTIVE: In contrast with the non-opiate dependent population, persons biologically-dependent upon opioids display an excess life-time prevalence of affective and anxiety disorders. Many of these addicts state that opiates, particularly methadone, relieve or diminish the severity of their dysphoria. The purpose of this study is to explore this phenomena by ...
Gaudet J P - - 1995
Birth order position for affected siblings was examined for 88 sibships having 2 or more cases of multiple sclerosis (MS). The data show that MS patients are randomly ordered by birth within these multiplex sibships. The data therefore do not support the hypothesis that MS occurs in siblings because of ...
Gaudet J P - - 1995
Birth order position was examined in 164 cases with sporadic multiple sclerosis (MS), i.e. no other family members with MS, and spousal controls, matched for sibship size, socioeconomic status and opposite sex. The results did not find an association between birth order position and the subsequent development of MS and ...

The frequency of schizophrenia may have increased during the early stages of industrialization and may now be declining. Early in the process of development, the illness appeared to be more common among the upper classes and later, more common in the lower classes. As with certain other diseases, the occurrence ...
McGrath J J - - 1994
The dates of birth of patients who were admitted with schizophrenia to public hospitals in Queensland between the years 1972 and 1988 were examined for associations between risk of schizophrenia and influenza epidemics. The hypothesis that infants born between four and six months after an influenza epidemic onset have increased ...
Rifkin L - - 1994
BACKGROUND: Low birth weight has been postulated to be a risk factor for schizophrenia. METHOD: Obstetric history, premorbid adjustment, and cognitive function during admission were assessed in 167 patients with DSM-III schizophrenia or affective psychosis. RESULTS: A birth weight of less than 2500 g was significantly more common in patients ...
O'Callaghan E - - 1994
BACKGROUND: Recently, several investigators have reported an association between influenza epidemics and increased birth rates of 'preschizophrenic' individuals some four to six months later. Here we examine whether maternal exposure to other infectious diseases can also predispose the foetus to later schizophrenia. METHOD: Two independent sets of dates of birth ...

Seasonal differences in bone mineral indices have not been studied in newborn infants. In adults, indicators of bone metabolism may show seasonal variations. In postneonatal infants and possibly in adults, vitamin D metabolism shows seasonal variations. We hypothesized that in winter-born infants, the bone mineral content is low and serum ...
d'Amato T - - 1994
Many studies have established that birth dates during the winter and early spring months are more common in schizophrenic patients than in the general population. It has been hypothesized that children born in winter are more likely to be exposed to environmental factors which could lead to the development of ...

Each month, for 15 months, the testes and epididymides were recovered from five Australian cashmere bucks selected at random from a group of mature bucks (initial n = 116) at pasture (location 29 degrees S, 153 degrees E). The extent of seasonal change in testicular and epididymal sperm reserves was ...
Takei N - - 1994
The question of whether prenatal exposure to influenza epidemics is associated with an increased risk of later schizophrenia remains controversial. The authors examined this relationship, using data on the dates of birth and gender of 3,827 schizophrenic patients born in England and Wales between 1938 and 1965 and first admitted ...
WolaƄski N - - 1994
The paper is focused on the seasonal pattern of birth and occurrence of menarche in different populations. The material collected in 1988/89 consists of 522 girls and their 249 mothers from schools of Merida, and of 135 girls and their 66 mothers from Progreso (Yucatan, Mexico). Occurrence of a biorhythm ...
Pallast E G - - 1994
In this study we examined whether the well-known winter excess of schizophrenic births exists among Dutch schizophrenia patients when statistical artifacts such as the age-incidence and age-prevalence effects are avoided and, if so, whether the seasonal preovulatory release of overripe ovum (SPrOO) hypothesis, that is, seasonally bound ovopathy, might be ...
Aschauer H N - - 1994
We examined the birth distribution of 2,450 schizophrenic and 682 schizoaffective patients first admitted between 1971 and 1992 to the University Hospital for Psychiatry in Vienna. Our data showed an excess of schizophrenic births in the first quarter of the year and a deficit in the third quarter compared with ...
Takei N - - 1993
We examined the relationship between influenza epidemics and the number of schizophrenic and affective psychotic individuals born each month between 1938 and 1965 in England and Wales. Increased death rates from influenza were followed 5 months later by a significant increase in schizophrenic births and a concurrent fall in the ...
