Mother's Depression Linked to Child's Shorter Height
Pygmies are short because nature made them so - Gene Expression
Mothers who report having symptoms of depression in the first year after giving birth may be likely to have shorter children, according to a study published Monday in the journal Pediatrics. They found that kids around age four with mothers who reported having mild or moderate depression during their child's infancy were more than 40 percent more likely to have children with short stature compared to mothers who did not report depressive symptoms. The study suggests that a link between the mother's depression and the child's height persists several years after the mother's reported depression, according to Pamela Surkan, an assistant professor of public health at Johns Hopkins Bloomberg School of Public Health and lead author of the study. However, for some kids the stunted growth didn't last. The short stature only persisted through age 5 in those with moderate depression, according to the study.
Patients with Turner's syndrome achieved significantly greater adult height when treated with growth hormone injections, according to long-term follow-up data from a randomized trial. Girls treated with growth hormone achieved an adult height 5 cm 2 inches taller than that of a placebo group, as reported in the March 31 issue of the New England Journal of Medicine. And the height of those who received both low-dose oral estrogen plus growth hormone was 2 cm 0.
Tallness has always been viewed as a desirable physical trait — so desirable that more than a century ago, Sir Francis Galton began collecting measurements of British schoolchildren as a prelude to his dream of breeding genetically superior human beings. Galton both coined the term and developed the statistics that allowed percentiles to be plotted on a growth chart. Since physical size is such an intrinsic feature of basic not to mention personal biology, researchers have returned again and again to that fateful intersection of genes, environment and stature. When they throw human qualities like cognition or intelligence into the mix, the combination becomes both fascinating and dangerous, not least because of the half-baked lessons that sometimes make their way from the technical literature to dinner party conversations.
