The influence of repeated lockdowns on mental health and social isolation is unknown. We conducted a longitudinal study of the influence of repeated mild lockdowns during two emergency declarations in Japan, in May 2020 and February 2021. The analyses included 7893 people who participated in all online surveys. During repeated mild lockdowns, mental and physical symptoms decreased overall, while loneliness increased and social networks decreased. Subgroup analyses revealed that depression and suicidal ideation did not decrease only in the younger age group (aged 18-29 years) and that younger and middle-aged people (aged 18-49 years), women, people with a history of treatment for mental illness, and people who were socially disadvantaged in terms of income had higher levels of mental and physical symptoms at all survey times. Additionally, comprehensive extraction of the interaction structure between depression, demographic attributes, and psychosocial variables indicated that loneliness and social networks were most closely associated with depression. These results indicate that repeated lockdowns have cumulative negative effects on social isolation and loneliness and that susceptible populations, such as young people and those with high levels of loneliness, require special consideration during repeated lockdown situations.
反复封锁对心理健康和社会隔离的影响尚不清楚。我们在日本 2020 年 5 月和 2021 年 2 月两次紧急声明期间进行了一项关于反复轻度封锁影响的纵向研究。该分析包括参与了所有在线调查的 7893 人。在反复的轻度封锁期间，心理和身体症状总体上有所减轻，而孤独感增加，社交网络减少。亚组分析显示，抑郁和自杀意念仅在年轻人群体（18-29 岁）中没有减少，而且年轻和中年人群体（18-49 岁）、女性、有精神疾病治疗史的人以及在收入方面处于社会劣势地位的人在所有调查时间的心理和身体症状水平都更高。此外，抑郁、人口统计学属性和社会心理变量之间的互动作图的综合提取表明，孤独感和社交网络与抑郁的关联最密切。这些结果表明，反复封锁对社会隔离和孤独感有累积的负面影响，易受影响的人群，如年轻人和孤独感较高的人群，在反复封锁期间需要特别考虑。
