Research shows initial COVID-19 lockdowns increased population mental distress. Yet, the mental health impact of repeated lockdowns in England remains unknown.

To: (a) explore changes in population mental health symptoms over the COVID-19 pandemic period (March 2020 to March 2021) in England, comparing this with trends from a decade before (2009–2019) as well as after (2021–2023); (b) compare the mental health impact of each of the three lockdowns in England with periods of eased restrictions, determining who was most affected; (c) examine the impact of demographics and distinct time periods on the prevalence of mental health symptoms.

A secondary analysis of a national longitudinal cohort study, utilising data from Waves 1–13 of the UK Household Longitudinal Study and from Waves 1–9 of the COVID-19 Survey. Mental health was assessed using the 12-item General Health Questionnaire. Student t-tests and logistical regressions were conducted.

There was a significant increase in the prevalence of self-reported symptoms of mental health during England's pandemic period, encompassing three lockdowns, compared with the average of rates from 10 years before. Rates of reported mental health symptoms were not significantly different across each lockdown, but were significantly higher than pre-pandemic rates, declining with eased restrictions. Rates from the end of lockdown to May 2023 revealed elevated mental health symptoms compared with pre-pandemic. Elevated symptoms were observed for women, people homeworking, those with health conditions, individuals aged 30–45 years and those experiencing loneliness.

Repeated lockdowns in England had a substantial impact on mental health, indicating requirements for ongoing mental health support.

Coercive measures such as involuntary psychiatric admission are considered a last resort in the treatment of people with psychiatric disorders. So far, numerous factors have been identified that influence their use. However, the link between a pandemic – in particular, restrictions such as lockdowns – and the use of involuntary psychiatric admission is unclear.

To examine the association between COVID-19 lockdowns and involuntary psychiatric admissions in Austria.

This retrospective exploratory study assessed all involuntary psychiatric admissions and use of mechanical restraint in Austria, except for the federal state of Vorarlberg, between 1 January 2018 and 31 December 2020. Descriptive statistics and regression models were used.

During the 3-year study period, 40 012 individuals (45.9% females, mean age 51.3 years) had 66 124 involuntary psychiatric admissions for an average of 10.9 days. Mechanical restraint was used during 33.9% of these admissions. In weeks of nationwide COVID-19 lockdowns (2020 v. 2018/2019), involuntary psychiatric admissions were significantly fewer (odds ratio = 0.93, P = 0.0001) but longer (11.6 (s.d.: 16) v. 10.9 (s.d.: 15.8) days). The likelihood of involuntary admission during lockdowns was associated with year (2020 v. 2018–2019; adjusted odds ratio = 0.92; P = 0.0002) but not with sex (P = 0.814), age (P = 0.310), use of mechanical restraint (P = 0.653) or type of ward (P = 0.843).

Restrictions such as lockdowns affect coercive measures and resulted in fewer but longer involuntary psychiatric admissions during weeks of lockdown in Austria. These results strengthen previous findings that showed the dependence of coercive measures on external factors, highlighting the need to further clarify causality and desired prevention effects when using coercive measures.
