We investigate whether and to what extent income dissatisfaction (ID) is an important determinant of migraine. Indeed, ID may play a more relevant role in migraines than realized income, and it may affect both low and high-income people.
We exploit the Italian Statistical Institute (ISTAT) survey covering about 80,000 individuals for this study. On the methodological ground, an instrumental variable probit model has been implemented.
To measure income dissatisfaction we exploit a self-reported status ranging from 1 to 4, while the migraine variable captures whether the individual suffers from migraine.
The results show that the higher the ID the greater the probability of having a migraine. This relationship is robust to the level of realized income, socioeconomic characteristics of the individual, and the existence of other illnesses.
The high relevance of ID among low-income as well as high-income people opens up a new perspective on the determinants of migraines and provides an explanation of the contrasting evidence in the literature about the income-migraine nexus.
我们研究收入不满（ID）是否以及在何种程度上是偏头痛的重要决定因素。事实上，收入不满在偏头痛中可能比实际收入发挥更重要的作用，并且它可能影响低收入和高收入人群。
我们利用意大利统计局（ISTAT）对约8万人进行的调查开展本研究。在方法层面，实施了工具变量概率单位模型。
为衡量收入不满，我们采用了从1到4的自我报告状态，而偏头痛变量则记录个体是否患有偏头痛。
结果表明，收入不满程度越高，患偏头痛的概率就越大。这种关系不受实际收入水平、个体社会经济特征以及其他疾病存在情况的影响。
收入不满在低收入和高收入人群中高度相关，这为偏头痛的决定因素开辟了新视角，并为文献中关于收入与偏头痛关系的矛盾证据提供了解释。
