The effects of a hypertension diagnosis on health behaviors: A two‐dimensional regression discontinuity analysis
利用二维断点回归设计，研究发现收缩压超过诊断阈值的人会显著调整生活方式（如减少脂肪摄入和戒烟），而舒张压超过阈值的人则没有，原因在于后者工作更忙、竞争更激烈，难以改变习惯。
This paper explores how a diagnosis of hypertension might affect a person's health-related behaviors. The analysis uses a two-dimensional regression discontinuity design because hypertension is diagnosed when a person's systolic or diastolic blood pressure (SBP or DBP) surpasses a pre-established threshold. We find that those closely above the SBP threshold significantly adjusted their lifestyle, such as reducing daily fat intake and quitting smoking, while those just surpassing the DBP cutoff did not. Further mechanism analysis suggests that the possibility of constraints, rather than education and income gradients, does more to explain the disparate behaviors of subjects near the SBP and DBP thresholds. Those around the DBP threshold generally have tighter work schedules and undertake more competitive jobs, which hinder them from improving their lifestyle. Overall, our findings complement the existing literature by posing a new perspective for understanding people's potential reluctance to adjust their behavior.
