Premature, Low Birthweight Infants More Likely If Pregnancy Was Less Than 18 Months Or More Than Five Years After Previous Birth, Study Says
Women who have previously given birth are more likely to deliver premature or low birthweight infants in subsequent pregnancies if they become pregnant sooner than 18 months or later than 59 months after the previous birth, according to a study published in the April 19 edition of the Journal of the American Medical Association, the Los Angeles Times reports (Gellene, Los Angeles Times, 4/19). Agustin Conde-Agudelo, of the Fundacion Santa Fe de Bogota and a World Health Organization consultant, and colleagues examined data from more than 11 million pregnancies from more than 67 previous studies conducted on six continents (Bloomberg, 4/18). Researchers compared the time spans between pregnancies among the women and the outcomes of the pregnancies. The study finds that women whose pregnancies were less than six months apart had a 40% higher risk of giving birth prematurely and a 61% higher risk of delivering an infant with a low birthweight, compared with women who had pregnancy gaps of between 18 months and 23 months. In addition, women who delivered infants more than 59 months after their previous pregnancy had a 20% to 43% increased chance of "adverse outcomes," BBC News reports (BBC News, 4/18). The risk of premature birth increased 1.9% for each month under 18 months between pregnancies and increased 0.6% for each month longer than 59 months, according to the study (Johnson, AP/Seattle Post Intelligencer, 4/18). Conde-Agudelo said the researchers controlled for factors such as socioeconomic conditions, which allows the findings to be "applied [in] both developed and developing countries." Conde-Agudelo added that a separate analysis of only U.S.-based studies yielded similar findings (Los Angeles Times, 4/19). The researchers wrote that the study "should furnish a strong motivating force for health personnel to provide family planning" (Reuters Health, 4/18). Rachel Royce of the Research Triangle Institute International in a related editorial writes that although "birth spacing" is a stated strategy for reducing child mortality in the U.N. Millennium Declaration, "its potential seems underemphasized," adding, "Interventions that increase birth spacing could positively affect both maternal and child health" (Howard Price, Washington Times, 4/19).
