The impact of COVID-19 on smoking cessation in pregnancy.

Abstract

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. 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. 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 didnot 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). Smoking cessation rates in pregnant women and the demand for antenatal smoking cessation services was unchanged during compared to before the COVID-19 pandemic.
