The relationship between happiness and health.

快乐是心理健康的一个重要组成部分，这一概念越来越受欢迎。研究人员报告说，快乐有益于身体健康，但目前的研究有限。此外，评估身体健康对幸福的影响的研究也很有限。使用流行病学方法，我将在一个数据库中调查幸福和健康之间的关系，该数据库收集了15年来在三个时间点收集的相同15,000人的测量数据。

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.
