Background and Purpose: Postnatal depression (PND) is prevalent in the general
population in Japan. However, there are no data on the actual condition and related
factors for PND in Chinese women in Japan, which is the largest group of foreign women
living in Japan. This study was performed to clarify the tendency of PND and its related
factors in Chinese mothers living in Japan. Methods: We carried out a mailed selfadministered
questionnaire survey among Chinese mothers living in Japan who had given
birth to a baby in the previous 3-4 months. Survey items included the status of mothers
and children, family support, and the Edinburgh Postpartum Depression Scale (EPDS).
Logistic regression analysis was utilized for statistical analysis. Results: The proportion of
high-PND-risk respondents among the 80 participants was 36.3%. The results indicated
that the factors affecting PND risk are parenting loneliness (Odds ratio: 7.416, p=0.003)
and support from the husband( Odds ratio: 0.357, p=0.047). Conclusion: The loneliness of
child-rearing and the support status of the husband in the 3rd-4th month after childbirth
are DNP risk factors for Chinese mothers in Japan. The presence of support from the
husband will not only be helpful in housework and childcare, but will also support the
mother’s spirit and alleviate the loneliness of child-rearing. In addition, as the PND risk
of Chinese mothers is high in the 3rd- 4th month after childbirth, it is necessary to
strengthen mental support during this period.
