The relationship between happiness and productivity, health risk-factors for chronic disease and morbidity.

幸福感是心理健康的重要组成部分，这一观点越来越受欢迎。研究人员报告说，幸福有益于身体健康，但目前的研究有限。此外，评估身体健康对幸福感影响的研究有限。使用流行病学方法，我将在一个数据库中调查幸福与健康之间的关系，该数据库在15年内收集了15，000人在三个时间点的测量结果。

The notion that happiness is an important component of mental health is gaining popularity. Researchers have reported that happiness benefits physical health, however there is currently limited research. In addition, there is limited research assessing the affect of physical health on happiness. Using epidemiological methods, I will investigate the relationship between happiness and health in a database that has measurements collected at three time points in the same 15,000 people over 15 years.
