The impact of COVID-19 on smoking cessation in pregnancy

Abstract

Objectives: A greater proportion of non-pregnant smokers attempted to stop smoking during compared to before the COVID-19 pandemic. The objective of this study was to determine if a greater proportion of pregnant women also attempted to stop smoking during the pandemic rather than before. Methods: The use of antenatal smoking cessation services and nicotine replacement therapies (NRT) in pregnant women was audited before (2019-2020) and during the COVID pandemic (2020-2021). Anonymised data from January 2019 to March 2021 were analysed from the Lambeth and Southwark smoking cessation service. Results: A total of 252 pregnant women who smoked were referred to their local antenatal smoking cessation service, of which 90 (35.7%) (median age: 31 years [19-52 years]) chose to attend smoking cessation clinics. The COVID-19 pandemic was not associated with an increase in the number of women attending smoking cessation clinics, (2020-2021 n=46 [40.8%] of 110); compared to (2019-2020 n=44 [30.9%] of 142 referred pregnant women pre-pandemic) p=0.061. Eighty-two women utilised NRT to help them stop smoking and the frequency of NRT use did not change during the pandemic (2019-2020 n=39, 2020-2021 n=43; p=0.420). No significant difference in smoking cessation rates between the two periods was observed at either the four-week (p=0.285) or twelve-week follow-up (p=0.829). Conclusions: Smoking cessation rates in pregnant women and the demand for antenatal smoking cessation services was unchanged during compared to before the COVID-19 pandemic.
