Mums' height linked to child deaths in India
Washington, April 22 (ANI): A study conducted in India has found that kids born to short women were 70 percent more likely to die before age 5 than those born to taller women.
The study, carried out by researchers at the Harvard School of Public Health (HSPH), revealed an association between the height of mothers and several indicators of her children's health, including risk of death, risk of being underweight, and anemia.
The research team found that children with mothers shorter than 4 foot 9 inches were 70 percent more likely to die than those whose mothers were at least 5 foot 3 inches tall.
Maternal height was viewed as an indicator reflecting a mother's own childhood health environment, and thus the study suggests Indian women are effectively passing along their early health status to the next generation.
The study was conducted by Associate Professor S V Subramanian and Neetu John, a masters student, both in the HSPH Department of Society, Human Development and Health, and colleagues Leland Ackerson from the University of Massachusetts, Lowell, and George Davey Smith, the University of Bristol, United Kingdom.
For the study, the researchers used data from India's 2005-06 National Family Health Survey, which is taken from a representative sample of households across India. More than 50,000 children under age five were included in the survey.
The researchers specifically looked at the height of mothers and health indicators for children under age five. Because a mother's height may reflect her own childhood health status, there is a plausible link between her stature and her child's health.
According to some scientists, the size of a woman's uterus may be the biological link between her height and her child's health, with a smaller uterus leading to more complications during pregnancy and therefore less healthy children, even though the precise mechanism through which this association is expressed remains unclear.
A key finding of the study is the critical discovery that the effects of a mother's own childhood health could impact the health of the children she may have many years later.
"Our findings suggest the presence of inter-generational transfer of poor health from mother to offspring," Notably, since maternal height itself is a consequence of a mother's childhood environment, our study is suggestive of the long-run and durable adverse impact of poor childhood conditions of the mother on the health of her offspring 15 to 30 years later," Subramanian said.
The study will be published in the April 22/29, 2009 issue of the Journal of the American Medical Association (JAMA). (ANI)
