性別影響身體質量指數與神經質指數相關之研究：社區成人樣本

Gender Infl uences the Correlation between Body Mass Index and Neuroticism Score in a Community Adult Sample

目的：過去精神醫學相關研究中，神經質與身體質量指數(bodymassindex,BMI)被認為是重要變項。然而許多研究指出，神經質有和身體質量指數可能有相關。方法：本實驗在驗證1,230位社區受試者中，研究神經質與身體質量指數的相關性。神經質是由Maudsley人格量表分測驗中測得。身體質量指數由受試者的身高及體重資料計算出來。結果：相關分析顯示神經質與身體質量指數有顯著的負相關。然而再考慮性別因素影響後就無相關性。結論：性別因素可能混淆身體質量指數與神經質的相關。

Background: Body mass index (BMI) and neuroticism are used to be treated as important variables in psychiatric research. But, several previous researches have shown that there may be a correlation between those two variables. Methods: This study investigated the correlation between BMI and the neuroticism score in 1,230 participants from the community. Neuroticism score was assessed using the Maudsley Personality Inventory. Results: Correlation analysis showed that BMI was negatively correlated with neuroticism score (r = -0.09, p = 0.003). But the correlation disappeared after considering the gender effect. Conclusion: The gender effect may confound the correlation between BMI and neuroticism score.
