Child siblings may influence each other’s obesity risk
(Reuters Health) – Brothers or sisters might have a greater influence than parents on a child’s likelihood of being obese, suggests new U.S. research.
The study, based on data from the larger national Family Health Habits Survey, found that kids with obese parents were about twice as likely to be obese themselves, but having an obese sibling raised a child’s risk of obesity five-fold or more in some cases.
“When you look at a two-child family, a child’s obesity status was more strongly related with their sibling than with their parent,” said Mark Pachucki, a researcher with the Mongan Institute for Health Policy at Massachusetts General Hospital in Boston, who led the analysis.
Lesbian shared biological motherhood: the ethics of IVF with reception of oocytes from partner http://link.springer.com/article/10.1007/s11019-013-9538-5 #springerlink
In vitro fertilization (IVF) with reception of oocytes from partners (ROPA) allows lesbian mothers to share biological motherhood. The gestational mother receives an egg from her partner who becomes the genetic mother. This article examines the ethics of IVF with ROPA with a focus on the welfare of the woman and the resulting child, on whether ROPA qualifies as a “legitimate” medical therapy that falls within the goals of medicine, and on the meaning and value attributed to a biologically shared bond between parents and child. We also contrast IVF with ROPA with egg donor IVF for heterosexual couples and intrafamilial live uterus transplantation with IVF, and show how Swedish legislation makes certain ways of sharing biological bonds out of place. In Sweden, IVF with ROPA is illegal, egg donor IVF for heterosexual couples is allowed and practiced as is sperm donor IVF for lesbians, and live uterus transplantation is performed within a research project (though not allowed in regular health care). But is ROPA really ethically more problematic than these other cases? The article argues that IVF with ROPA gives rise to fewer ethical questions than does live uterus transplantation with IVF and, in some cases, egg donor IVF.
This book examines, through a multi-disciplinary lens, the possibilities offered by relationships and family forms that challenge the nuclear family ideal, and some of the arguments that recommend or disqualify these as legitimate units in our societies.
That children should be conceived naturally, born to and raised by their two young, heterosexual, married to each other, genetic parents; that this relationship between parents is also the ideal relationship between romantic or sexual partners; and that romance and sexual intimacy ought to be at the core of our closest personal relationships – all these elements converge towards the ideal of the nuclear family.
The authors consider a range of relationship and family structures that depart from this ideal: polyamory and polygamy, single and polyparenting, parenting by gay and lesbian couples, as well as families created through current and prospective modes of assisted human reproduction such as surrogate motherhood, donor insemination, and reproductive cloning.
