OBJECTIVE To study the prevalence of potentially life-threatening maternal conditions and near miss in Brazil according to maternal age. METHODS A secondary analysis of the 2006 Brazilian demographic health survey database using a validated questionnaire to evaluate maternal morbidity with a focus on age extremes. The study included 5,025 women with at least 1 live birth in the 5-year referen...

the aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of moghani sheep, using random regression models based on b-splines functions. the data set included 9165 body weight records from 60 to 360 days of age from 2811 moghani sheep, collected between 1994 to 2013 from jafar-abad animal research and breeding institute, ardabil province,...

BACKGROUND Age of puberty has declined substantially in developed settings and is now declining in the rest of the world with economic development. Early age of puberty is associated with non-communicable diseases in adulthood, and may be a long-term driver of population health with effects over generations. In a non-Western setting, we examined the association of maternal age of menarche with ...

BACKGROUND Although a number of studies have investigated correlations of maternal age with birth outcomes, an extensive assessment using age as a continuous variable is lacking. In the current study, we estimated age-specific risks of adverse birth outcomes in childbearing women. METHOD National population-based data containing maternal and neonatal information were derived from the Health P...

OBJECTIVE To explore the association between maternal and paternal age and risk of autism spectrum disorders (ASDs) in offspring. DESIGN Historical birth cohort study.

introduction: genetic resources in any country are valuable materials which needed to be conserved for a sustainable agriculture. an animal phenotype is generally affected by genetic and environmental factors. to increase mean performance in a population under consideration not only environmental conditions, but also genetic potential of the animals should be improved. although, environmental i...

Average maternal age at birth has been rising steadily in Western and some Asian countries. Older maternal age has been associated with adverse pregnancy and birth outcomes; however, studies on the relationship between maternal age and young children's health remain scarce. Therefore, we sought to investigate the association of maternal age with child health outcomes in the Japanese population....

This article is a longitudinal investigation of the relationships between maternal victimization, maternal functioning, and children's behavior and development. Participants include 203 mother-child dyads from a low-income population recruited from pediatric primary care clinics. Data are collected when children are 4 and 8 years of age. Child outcomes are evaluated using maternal, teacher, and...
