Telomeres are repeating DNA sequences at the ends of chromosomes that protect and buffer genes from nucleotide loss as cells divide. Telomere length (TL) shortens with age in most proliferating tissues, limiting cell division and thereby contributing to senescence. However, TL increases with age in sperm, and, correspondingly, offspring of older fathers inherit longer telomeres. Using data and ...
The current study examines the association between low birth weight and risk for major depression from early adolescence to early adulthood. It accounts for eight documented confounders, and depression within families. Data were analyzed from the National Longitudinal Survey of Youth 1979 on mothers and offspring. Major depression was assessed with the Center for Epidemiologic Studies Depressio...
Maternal smoking during pregnancy is associated with low birth weight. Common variation at rs1051730 is robustly associated with smoking quantity and was recently shown to influence smoking cessation during pregnancy, but its influence on birth weight is not clear. We aimed to investigate the association between this variant and birth weight of term, singleton offspring in a well-powered meta-a...
OBJECTIVE To evaluate whether the risk for birth defects associated with maternal diabetes is attenuated by use of multivitamin supplements during the periconceptional period. METHODS In the population-based Atlanta Birth Defects Case-Control Study, we identified case infants who had nonsyndromic birth defects that were reported to be associated with diabetes (n = 3278) and were born during 1...
Average paternal age is increasing in many high income countries, but the implications of this demographic shift for child health and welfare are poorly understood. There is equivocal evidence that children of older fathers are at increased risk of neurodevelopmental disorders and reduced IQ. We therefore report here on the relationship between paternal age and a composite indicator of scholast...
purpose: to determine the frequency and severity of retinopathy of prematurity (rop) among singleton and multiple-birth neonates referred to farabi eye hospital, tehran-iran. methods: we reviewed the records of 99 consecutive neonates from multiple-gestation pregnancies including 68 twins, 26 triplets and 5 quadruplets who were screened for rop during 2002-2004. the frequency, severity and risk...
OBJECTIVE Although adolescent alcohol use has been consistently associated with parental drinking behavior, sibling drinking behavior and family functioning, the extent to which these associations owe to genetic or shared environmental influences has not been previously investigated. Using an adoption study design, we sought to determine whether the familial correlates of adolescent alcohol inv...
Paternal age at birth, a potential proxy of mutation load transmitted to the offspring, has previously been related offspring’s health, biological condition and reproductive potential. As higher facial asymmetry distinctiveness serve as putative markers lower genetic quality an individual, we hypothesize that more advanced paternal birth will be children’s levels distinctiveness. To best our kn...
Kind, Karen L., Peter M. Clifton, Arkadi I. Katsman, Maria Tsiounis, Jeffrey S. Robinson, and JulieA. Owens. Restricted fetal growth and the response to dietary cholesterol in the guinea pig. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R1675–R1682, 1999.— Epidemiological studies suggest that retarded growth before birth is associated with increased plasma total and lowdensit...
BACKGROUND Many public health and epidemiological studies have found differences between populations (e.g. maternal countries of birth) in average values of a health indicator (e.g. mean offspring birthweight). However, the approach based solely on population-level averages compromises our understanding of variability in individuals' health around the averages. If this variability is high, the ...
