Washington, Apr 21 (ANI): Shorter maternal height is associated with more deaths among children in developing countries, say researchers.
According to a new study from the Harvard School of Public Health (HSPH), mothers shorter than 4 feet, 9 inches in low- to middle-income countries had about a 40 percent higher risk of their children dying within the first five years of life than mothers who were 5 feet, 3 inches or taller.
The risk was higher—almost 60 percent—in the first 30 days after birth.
The study appears in the April 21, 2010 issue of the Journal of the American Medical Association.
“Height is a useful and stable marker of cumulative health,” said S.V. Subramanian, senior author of the paper and associate professor in the department of society, human development, and health at HSPH. “It is an indicator of the nutritional environment a person was exposed to during childhood, which shapes both the mother”s attained height and subsequent health as well as her offspring”s chances of survival or ability to grow in infancy and childhood.”
Subramanian and his co-authors, Emre Özaltin, a doctoral candidate in the department of global health and population at HSPH and lead author of the study, and Kenneth Hill, professor of the practice of global health at HSPH, analyzed health surveys from 54 low- to middle-income countries that included more than 2.6 million children and more than 750,000 mothers.
The researchers also found that a 1-centimeter—less than 0.4 inch— increase in height reduced the risk of child mortality by 1.2 percent. The same increase in height reduced the risk of underweight and growth failure by more than 3 percent.
“Health needs to be viewed not only as a phenomenon that spans one”s life, but one that also has a multigenerational aspect,” said Özaltin. “We believe that interventions to reduce child mortality and growth failure have not recognized the intergenerational transmission of poor health,” added Subramanian.
