Attitude and perceptions toward miscarriage: a survey of a general population in Japan

Abstract

Miscarriage is the greatest complication of pregnancy, and 70-80% of early miscarriages are mostly due to chromosomal abnormalities in the embryo. There is no evidence that stress is a direct cause of miscarriage. Despite these findings, in a national US survey on the causes of miscarriage, many Americans mistakenly attributed miscarriage to the mental state or behavior of the women. We conducted a survey to assess public attitudes and perceptions regarding the cause and prevalence of miscarriage in Japan. We sent out a questionnaire consisting of 17 questions. The 5000 recipients consisted of men and women (1:1 ratio) aged 18-69 who resided in Aichi Prefecture. A total of 1257 recipients (25%) responded to the questionnaire and 1219 valid respondents (24%) were included in the analyses. Of these, 62% considered a genetic abnormality of the fetus as the cause of miscarriage. Participants who were female, highly educated, married and healthy gave significantly more correct responses. On the other hand, the majority wrongly assumed that a stressful event (65%) and long-standing stress (75%) to be causes of miscarriage. Participants who had no history of miscarriage as well as males answered significantly more incorrectly. Sixty-five percent of respondents thought that miscarriage occurred less than 15% of all pregnancies. Among respondents who had experienced miscarriage personally, 53 and 36% felt guilty and lonely, respectively. Many respondents blamed the woman for the miscarriage either in terms of her behavior or mental stress and considered the frequency of miscarriage to be lower than it actually is.
