The effects of exercise during pregnancy on mother and fetus are of concern. The literature on this issue, however, is limited. Using the 1988 National Maternal and Infant Health Survey (NMIHS) data, this dissertation focuses on three topics: (1) exercise during pregnancy in U.S. women; (2) exercise during pregnancy and fetal growth; and (3) exercise during pregnancy and pregnancy-induced hypertension (PIH). The results were presented in a format of three separate manuscripts suitable for publication.Subjects--Topical Terms:

520 $a The effects of exercise during pregnancy on mother and fetus are of concern. The literature on this issue, however, is limited. Using the 1988 National Maternal and Infant Health Survey (NMIHS) data, this dissertation focuses on three topics: (1) exercise during pregnancy in U.S. women; (2) exercise during pregnancy and fetal growth; and (3) exercise during pregnancy and pregnancy-induced hypertension (PIH). The results were presented in a format of three separate manuscripts suitable for publication.
520 $a In a national representative sample of 9953 women who had live births in 1988 and participated in the NMIHS, 42% reported exercising during pregnancy. Walking was the leading activity (43%), followed by swimming (12%) and aerobics (12%). The prevalence of exercise during pregnancy and the specific activities varied by geographic regions, races and occupations. Older mothers, women who had multiple gestations, previous children, or unfavorable reproductive history were less likely to exercise during pregnancy.
520 $a After the exclusion of women with missing information or pregnancy complications, 2347 women were left for the examination of the association between exercise and fetal growth. Fetal growth was measured by birthweight, placenta weight, head circumference, crown-heel length, ponderal index, and risk of low birthweight ( $< $2 500g), below the 10th and 25th percentile of birthweight distribution in the U.S. population. After adjusting for duration of gestation, as well as other factors, the neonatal morphology indices were not significantly different between women with self-reported exercise and those without. This study indicates that self-reported exercise in pregnancy does not affect fetal growth.
520 $a The association of exercise in pregnancy with PIH was examined by a case-control study approach. Two PIH case groups were selected by two independent diagnostic criteria (N = 187 and 207 respectively) and compared with a control group (N = 1388). After controlling for a number of factors, women who exercised, especially before and during pregnancy tended to have lower risk of PIH than those who never exercised (adjusted odds ratio = 0.8 and 0.6, 95% confidence interval = 0.6-1.2 and 0.4-0.9 for the two case groups respectively). This study suggests that exercise in pregnancy may reduce the risk of PIH.
520 $a The physiological mechanisms of these associations were reviewed and discussed, and the limitations of the studies were fully assessed in each manuscript and the Integrative Comments.
