抄録

BACKGROUND：Sedentary behavior has been reported to be deleteriously associated with several health outcomes of pregnant women and their own baby. However, there are no studies examining pattern of sedentary behavior and its associated factors in pregnant women in Japan. OBJECTIVE：The present study aimed to describe actual sedentary behavior and identify its associated factors among pregnant women. METHODS：A self-reported questionnaire （e.g. basic attributes, exercise status, health status during pregnancy） was firstly conducted with 10 first child-birth women who were pregnant in the previous year. Next, for the first and second trimesters and two categories of third trimesters （<37 weeks and >=37 weeks pregnancy）, they were asked about the sedentary time status （including changes from the previous period） and the reasons for it with personal semi-structured interview. The Kawakita-Jiro （KJ） method was used for analysis. RESULTS：In pregnant women, sedentary behavior increased in the first trimester, decreased in the second trimester, and increased in the third trimester. Changes in physical functions due to pregnancy and its discomfort, anxiety about the continuation of pregnancy, excessive social support from their husband, family, and colleagues, low health literacy and inaccurate information acquisition related to pregnancy, and the maternity leave system were extracted as major associated factors of sedentary behavior throughout the perinatal period. CONCLUSION：Physical, mental, social, and environmental factors were alternatively associated with sedentary behavior. Some identified factors could be modified with the intervention.
