Caught in the Bulimic Trap?
利用NHLBI成长与健康研究数据和工具变量方法，发现暴食症的持续性中状态依赖占三分之二，未观测异质性也起作用，表明早期干预和康复治疗结合至关重要。
Abstract Bulimia nervosa (BN) is a growing health concern and its consequences are especially serious given the compulsive nature of the disorder. However, little is known about the mechanisms underlying the persistent nature of BN. Using data from the NHLBI Growth and Health Study and instrumental variable techniques, we document that unobserved heterogeneity plays a role in the persistence of BN, but up to two-thirds of it is due to state dependence. Our findings suggest that the timing of policy is crucial: Preventive educational programs should be coupled with more intense (rehabilitation) treatment at the early stages of the BN behaviors.
