INTRODUCTION Even though Ethiopia has been celebrating the achievements of MDG 4, still one in every 17 Ethiopian children dies before their first birthday. This is the biggest of the African regional average. Short birth interval is inconsistently reported as a risk factor by limited and independent studies in Ethiopia. Therefore, the purpose of this meta-analysis was to determine the pooled e...
Risk of congenital anomalies associated with antithyroid treatment during pregnancy: a meta-analysis
To evaluate the association of either propylthiouracil or methimazole treatment for hyperthyroidism during pregnancy with congenital malformations, relevant studies were identified by searching Medline, PubMed, the Cochrane Library and EMBASE. We intended to include randomized controlled trials, but no such trials were identified. Thus, we included cohort studies and case-control studies in thi...
OBJECTIVE: The objective of the study was to determine the maternal risk factors associated with “Low Birth Weight Babies”. STUDY DESIGN: Case control study.

Fertility analysis is important in understanding past, current and future trends of population size, Composition and growth. Information on fertility levels, patterns and trends experienced by a country is important for socio-economic planning, monitoring and evaluating programs. In recent years the study of birth intervals has acquired importance because of its relationships to fertility. The ...
Ages at menarche and first birth are established risk factors for breast cancer. The interval between these ages may also affect risk, since the breast is more susceptible to carcinogenic insults during this period than during the parous period. However, few investigators have studied this relation. Using logistic regression, the authors evaluated associations between the timing of reproductive...
The authors used 1982-1983 Illinois vital records and 1980 US Census income data to determine the contribution of maternal race to the risk of preterm (< 260 days), non-low birth weight (> 2,500 g) infants. This older cohort was chosen to avoid the confounding effect of cocaine associated with its increased local availability after 1985. In Chicago, the unadjusted preterm, non-low birth weight ...
BACKGROUND Although a family history of schizophrenia is the best-established risk factor for schizophrenia, environmental factors such as the place and season of birth may also be important. METHODS Using data from the Civil Registration System in Denmark, we established a population-based cohort of 1.75 million persons whose mothers were Danish women born between 1935 and 1978. We linked th...
The authors investigated the shape, sex- and age-dependency, and possible confounding of the association between birth weight and systolic blood pressure (SBP) in 197,954 adults from 20 Nordic cohorts (birth years 1910-1987), one of which included 166,249 Swedish male conscripts. Random-effects meta-regression analyses were performed on estimates obtained from age- and sex-stratified analyses w...
A meta-analysis of 37 studies on the effects of an intervention program on physiological development of the premature infant was conducted using multidisciplinary research reported since 1979. Two homogeneous populations based on mean infant birth weight were found in which infant stimulation programs were shown to be effective in enhancing physiological development (Group I: mean birth weight ...
