Offspring of Chronic Alcoholic Mothers
same observers (K. J. and D. W. S.). Four of these children were recognised as having a similar pattern of altered growth and morphogenesis. Thereafter, two other children were ascertained by the abnormal features identified in the first four patients, while the remaining two affected children were ascertained because their mothers were chronically alcoholic. The mothers of the affected patient...
متن کاملEarly growth in offspring of diabetic mothers.
OBJECTIVE By age 5 years, offspring of diabetic mothers (ODMs) are heavier and have altered glucose metabolism compared with offspring of mothers without diabetes (non-DMs). This study evaluates the growth pattern of ODMs before the age of 5 years. RESEARCH DESIGN AND METHODS Anthropometric measures (z scores) from birth, 1.5 years, and 7.7 years in Pima Indian children were compared by mater...
متن کاملPathways to Suicide-Related Behavior in Offspring of Mothers With Depression: The Role of Offspring Psychopathology
OBJECTIVE Offspring of mothers with depression are a high-risk group for the development of suicide-related behavior. These offspring are therefore a priority for preventive interventions; however, pathways contributing to risk, including specific aspects of offspring psychopathology, remain unclear. The aim of this study was to examine whether offspring symptoms of major depressive disorder (M...
متن کاملSelfish mothers? An empirical test of parent-offspring conflict over extended parental care.
Parent-offspring conflict (POC) theory is an interesting conceptual framework for understanding the dynamics of parental care. However, this theory is not easy to test empirically, as exact measures of parental investment in an experimental set-up are difficult to obtain. We have used free-ranging dogs Canis familiaris in India, to study POC in the context of extended parental care. We observed...
متن کاملMothers adjust offspring sex to match the quality of the rearing environment.
Theory predicts that mothers should adjust offspring sex ratios when the expected fitness gains or rearing costs differ between sons and daughters. Recent empirical work has linked biased offspring sex ratios to environmental quality via changes in relative maternal condition. It is unclear, however, whether females can manipulate offspring sex ratios in response to environmental quality alone ...
