地域住民のうつ状態の危険因子に関する研究

A Study on Risk Factors of Depression of Residents

　千葉県一農村の40歳から69歳までの住民1,046人を対象に，生活出来事が地域住民のうつ状態に及ぼす影響力を比較検討した。生活出来事は28項目を調査し，うつ状態はZungの自己評価式抑うつ尺度を用い判定し，その関連性を検討した。

　1．単変量解析の結果，うつ状態と有意に関連した出来事をみると，Distressが，配偶者の死，親族とのトラブル，けが・病気，退職で，Eustressが個人的な成功であった。

　2．ロジスティック回帰分析による多変量解析の結果，うつ状態の有意な危険因子は，浮気，配偶者の死，上司とのトラブル，けが・病気，収入の変化で，いずれもDistressであった。

　The purpose of this study was to estimate the effect of life events on depression of residents. We made a survey of 1,046 residents aged 40-69 in a farming village, Chiba Prefecture, and questioned 28 life events for the last one year. The correlation between life events and depression estimated by using Zung's Self-rating Depression Scale was analyzed by univariate analysis and multivariate analysis.

　From univariate analysis using Mantel-heanszel method, significant risk variables for depression were found to be death of spouse, trouble with relatives, injury/disease, and retirement as distress but personal success as eustress.

　From logistic regression analysis using gender and age as covariates, significant risk variables for depression were found to be inconstancy, death of spouse, trouble with a superior officer, injury/dis-ease and change of income as distress.
