| Outline of Final Research Achievements |
We elucidated the outcome of pregnancy and birthweight in women
with a normal non-pregnant weight 18.5≦BMI＜25(kg/m2) who were slightly underweight or slightly overweight during pregnancy. We retrospectively examined women with singleton pregnancies with no medical complications. They were classified into five groups according to their non-pregnant BMI: underweight, slightly underweight, normal, slightly overweight, and overweight.
Blood pressure during each trimester, duration of labor, estimated blood loss, and birthweight were evaluated. The slightly overweight group showed significantly higher blood pressure than the underweight and slightly underweight groups. Birthweight was significantly lower in the slightly underweight and underweight groups than in the slightly overweight and overweight groups. Management of pregnant women with normal non-pregnant BMI should be done by subdividing them into three groups: slightly underweight, normal, and slightly overweight.

| Academic Significance and Societal Importance of the Research Achievements |
ふつう体重の上限と下限にある妊婦はふつう体重の妊婦に比べて血圧の上昇や出生時体重が低下することが明らかになった。ふつう体重妊婦の管理は、下限にあるやせ傾向群と上限群、ふつう群の3群に分類し管理を行うことが望ましい。日本において近年，新生児の体重が低下していることへの対応のためにはやせ群のみではなく比較的高い割合を占めているやせ傾向群に焦点を当てた対策が必要である
