Outline of Final Research Achievements

As a survey to visualize the contents of physical activity in daily life of pregnant women and the amount of physical activity with accelerometer (Actiband, Toshiba) targeting 40 pregnant women were measured, and at the same time pregnant women was kept their daily activities recorded. As a result, the amount of physical activity of pregnant women increased significantly at the end of pregnancy in women who did not work during the pregnancy period, and the amount of activity did not change in women who continued to work. The amount of activity significantly decreased in women who stopped working during 3rd trimester of pregnancy period. It was suggested that the amount of activity decreased as work time became rest and leisure time. Also, focusing on sedentary time, it took 477-578 minutes, longer than the average of 420 minutes for Japanese adults.

Academic Significance and Societal Importance of the Research Achievements

妊婦の生活を含めた身体活動の実態が明らかとなり、これらの結果をもとに、妊婦に対する身体活動の保健指導へと貢献することができる。また妊娠期間中にの身体活動を維持させようとしても、新たな運動を行うことは難しい。妊婦の座位時間が、一般成人と比較して長時間であることを踏まえ、座位時間を減らす、というあたらなアプローチを用いた妊婦の身体活動の維持増進を働きかける介入プログラムの開発に貢献する。
