Outline of Final Research Achievements |
A longitudinal intervention study was changed to a cross-sectional observational study due to the influence of Covid-19. In total, self-rating scales were collected from 38 female patients with anorexia nervosa (AN) of a mean BMI of 13.8, meeting the diagnostic criteria in DSM-5, and their 38 mothers. Multiple regression analysis was conducted using EDE-Q 6.0 as the dependent variable and the relevant parameters as the independent variables after the adjustment by using propensity score. The results showed statistically or marginally significant differences in the relationship between the eating disorder pathology of AN patient and (1) mother's nurturing attitude or family relationship, (2) mother's mental state, and (3) social support for the mother. The results inferred that supports for the mother or psychoeduation including family focused intervention regarding mother-child relationship are related to AN pathology and, may contribute to the AN treatment.

Academic Significance and Societal Importance of the Research Achievements |
重症のANは、我が国でも少数の症例報告が中心であり、本研究ほどの規模で重症のAN患者のみを対象にし、かつ母子セットでデータを集めている疫学的報告は国内では殆ど認められない。多くの医療資源を費やす上に、予後不良で確立した外来治療の存在しない重症AN患者の今後の治療を検討する上で、本研究で得られたデータは貴重である。特に、母親に対するサポートを中心とした家族支援が、母親の精神状態や家族関係の改善を通じて、娘である重度AN患者の摂食障害の病態改善に寄与する可能性が示唆され、今後のさらなる家族支援のあり方を検討する上で貴重な研究と言える。今後、縦断的な介入研究を含めた一層の検証が求められる。
