ハイライト：

• 日本においてCOVID-19の症例が増加を始めた2020年2月末と4月初旬において地域住民における精神健康度の変化を検討した。
• 精神健康度不良者の割合は9.3%（2月末）から11.3％（4月初旬）へ増加がみられ、特に低年収の者および呼吸器疾患を有する者で悪化した者が多かった。
• COVID-19の予防対策とあわせメンタルヘルス対策を特に低年収層に対して行うことが重要である。

Highlights in English:

• Excess mortality from suicide was discussed to assess the impact of the COVID-19 pandemic in Japan.
• Excess mortality during the pandemic period was estimated using a time series model based on the number of suicides before the pandemic.
• No significant excess mortality was observed through the early pandemic period; instead, a downward trend in suicides for both sexes was visible.
• Our results suggest that various changes in the early period of the COVID-19 pandemic induced a decrease in suicides in Japan.
