Relationship between arteriolosclerosis of ocular fundus and depression among middle-aged men in an occupational setting: a five-year follow-up study.

本研究通过对神奈川县一家电力公司三家工厂的1524名工人进行随访，探讨了眼底小动脉硬化与抑郁症之间的关系。我们在1997 - 1999年进行了一次基线调查，我们与公司医生合作探讨了研究组的离职率，但由于公司个人信息政策的变化，我们不得不提前结束了后续调查。最后，我们在最初的1524人组中随访了1004人（分别来自1997年、1998年和1999年基线调查年的236人、197人和571人）。随访前有14人死亡。在没有跟进的506人中，有310人在1997年至2006年期间离开了该公司。我们分析了有关动脉硬化危险因素的数据，发现有a型行为的人更容易肥胖，而独居的人更容易受到HbAlc平均值升高的影响。该研究结果在日本经济学会和日本经济学会的科学会议上发表。

This study examines the relationship between arteriolosclerosis of the ocular fundus and depression, by following up a cohort that comprised 1524 workers at three factories of an electric company in Kanagawa prefecture. A baseline survey was previously conducted, from 1997 to 1999,We explored the job separation rate among the study group in cooperation with the company physician, although we had to prematurely end the follow-up survey because of change in the company personal information policy.Finally, we followed up with 1004 people (236, 197 and 571 people from the 1997, 1998 and 1999 baseline survey years, respectively) among the original group of 1524. Fourteen people died prior to follow-up. Among 506 persons who were not followed up, 310 left the company between 1997 and 2006.We analyzed the data in regards to arteriosclerosis risk factors and found that people with type-A behavior are likely to become obese and that those who live alone are likely to suffer from the increase of the average value of HbAlc. The results were reported at scientific meetings of the Nippon Koshueisei Gakkai and Nippon Ekigakukai.
