何金波教授和实验室研究生任遥翔发表合作研究成果
恭喜遥翔发表她的首篇学术论文。
近期，实验室研究生任遥翔作为论文第一作者，与香港中文大学（深圳）数据科学学院和深圳市大数据研究院卢超仪、杨涵、马千越、周健君博士，国外合作者Wesley R. Barnhart及何金波教授（通讯作者）在Journal of Eating Disorders发表合作论文Using machine learning to explore core risk factors associated with the risk of eating disorders among non‑clinical young women in China: A decision‑tree classification analysis. 本研究受深圳大数据研究院的资助。
Abstract
Background: Many previous studies have investigated the risk factors associated with eating disorders (EDs) from the perspective of emotion regulation (ER). However, limited research has investigated interactions between co-existing risk factors for EDs, especially in China where research in EDs is underrepresented.
Methods: This study examined core risk factors related to maladaptive eating behaviors and ER, and how their interactions affect the detection of EDs. Using machine learning, a decision tree model was constructed on a data set of 830 non-clinical Chinese young women with an average age of 18.91 years (SD = 0.95). The total data set was split into training and testing data sets with a ratio of 70 to 30%.
Results: Body image inflexibility was identified as the major classifier for women at high risk of EDs. Furthermore, interactions between body image inflexibility, psychological distress, and body dissatisfaction were important in detecting women at high risk of EDs. Overall, the model classifying women at high-risk for EDs had a sensitivity of 0.88 and a specificity of 0.85 when applied to the testing data set.
Conclusions: Body image inflexibility, psychological distress, and body dissatisfaction were identified as the major classifiers for young women in China at high risk of EDs. Researchers and practitioners may consider these findings in the screening, prevention, and treatment of EDs among young women in China.
遥翔的话:
在研一时非常荣幸进入何金波教授的Sci-Cream实验室，实验室以研究进食障碍，身体意象，饮食习惯，媒体等领域为主，非常符合我对心理健康领域的兴趣。能够参与此次进食障碍的相关研究和论文写作，并且接触到机器学习方法在进食障碍的前沿研究方向，是非常宝贵的学习机会。在论文的研究和写作期间，从数据分析讨论，到文章初稿的形成，再到一遍又一遍的精益求精，是何老师和大数据研究院周老师的指导下，与其他文章作者们共同努力的成果。在Sci-Cream实验室不但能学习到做研究的方法，写论文的经验，更能感受到老师的耐心栽培，在文章多次的修改中，何老师会从学术和心态上帮助我们更从容心态面对，更好地适应学术研究的生活。其次，在何老师积极开朗的态度影响下，实验室伙伴们相互支持，拥有非常棒的团队氛围，让做科研也可以丰富有趣起来，对于以后的学习研究和工作都助益无穷。再次庆幸和感谢在研究生阶段遇到何教授和各位实验室的伙伴，我相信自己会带着这一份的传承继续自己的研究和工作生涯。
