SOME FACTORS ASSOCIATED WITH PREMATURITY part II.

Effect of the Interval between Pregnancies on Perinatal Outcomes

“…In the few studies that have been conducted of the relation between short and long interpregnancy intervals and adverse perinatal outcomes, no definitive conclusions could be drawn because of methodologic constraints or because the number of women studied was small. [8][9][10][11] We addressed this question by studying vital-statistics data recorded in Utah. These data offer an excellent opportunity for evaluating the relation between interpregnancy intervals and birth outcomes because the average parity of mothers there is relatively high.…”

“…Similarly, in an analysis of data on 5301 births to multiparous British mothers from March 3 to 9, 1946, birth intervals of three to six years were associated with the lowest risk of birth weights less than or equal to 5.5 lb (2.5 kg). 9 The study, however, was based on birth interval, which overestimates the risk of adverse outcomes for short intervals between pregnancies. 2,3 Moreover, among white infants born in the United States during 1981, both short and long interpregnancy intervals correlated with an increased risk of low birth weight, 10 although that analysis did not consider maternal age.…”

Factors Associated with Impairment of the Early Development of Prematures

“…Previous studies of prematurity (e.g., Baird, 1945;Blegen, 1953;Douglas, 1950;Drillien, 1958;1959a;1959b;Eastman, 1947) have considered social factors because of the high prematurity rate in low social classes: The poorer development of such premature infants has sometimes been attributed to their poorer environments. Thus, social factors might represent a source of impairment independent of the insult variables and of low birth weight, but to some extent confounded with them.…”

Educação em saúde na prevenção do risco de desmame precoce

“…Há muito tem-se estudado os efeitos do intervalo intergestacional para a saúde materno-infantil 4,6,18,19 . Estes estudos têm--se limitado, entretanto, à análise de aspectos biológicos, sem se proporem a abordar seus efeitos dentro de uma perspectiva do tipo comportamental.…”
