长期的时间序列数据显示肥胖和吸烟率之间存在很强的负相关性，这可能无法反映因果关系。许多烟瘾很大的人声称，吸烟可以帮助他们保持苗条的身材，尽管吸烟对健康有危害，但他们仍然坚持吸烟。本研究使用日本家庭调查，调查了吸烟对身体形状的因果影响，日本的工作场所禁烟的外生变化。与以前的研究相反，我们的工具变量估计表明，吸烟对体重指数，肥胖和体重不足没有影响。我们还构建了一个过识别模型来测试我们的结果的鲁棒性。
Long‐term time‐series data show a strong negative correlation between obesity and smoking prevalence, which may not reflect the causality. Many heavy smokers claim that smoking helps them maintain a slim body and keep smoking despite the health risks. Using the Japan Household Panel Survey, this study investigates the causal effect of smoking on body shapes by exogenous variations of Japan's smoking ban in the workplace. Contrary to previous studies, our instrumental variable estimates show that smoking has no effect on body mass index, obesity and underweightness. We also construct an overidentified model to test the robustness of our results.
