The Impact of the COVID-19 Pandemic on Smoking Consumption: A Systematic Review of Longitudinal Studies

Cigarette Smoking Patterns Among Racial and Ethnic Groups With Chronic Lung Diseases During the COVID-19 Pandemic

Introduction

Chronic obstructive pulmonary disease and asthma are significant respiratory conditions that contribute to substantial morbidity and mortality globally. Chronic obstructive pulmonary disease remains the third most prevalent cause of death worldwide, with 90% of chronic obstructive pulmonary disease deaths attributed to combustible cigarette smoking. Asthma, although often less fatal, leads to considerable health burdens, particularly among marginalized populations who are at higher risk for both more severe chronic obstructive pulmonary disease and asthma outcomes. This study investigates the association between race/ethnicity and current cigarette smoking among adults diagnosed with chronic obstructive pulmonary disease and/or asthma in the U.S. before, during, and after the COVID-19 pandemic.

Methods

The authors analyzed data from 10,763 adults (aged ≥40 years) with a history of chronic obstructive pulmonary disease and/or asthma surveyed in the 2019, 2021, and 2023 National Health Interview Survey. The authors estimated predicted probabilities derived from multiple logistic regression and negative binomial regression models to examine changes in (1) the prevalence of current cigarette smoking in the target population, (2) the mean number of days of cigarette smoking in the past 30 days, and (3) the mean number of cigarettes smoked in the past 30 days across racial/ethnic subgroups and prepandemic, pandemic, and postpandemic periods.

Results

Current cigarette smoking was reported by about one fifth (20%) of U.S. adults diagnosed with chronic obstructive pulmonary disease and asthma. Among them, the mean number of days of cigarette smoking in the past 30 days was 27 days, and the mean number of cigarettes smoked in the past 30 days was 14. Hispanic individuals had the lowest prepandemic rates of current cigarette smoking (10.5%); however, it was the only racial/ethnic group showing a significant change during the pandemic, with rates increasing to 14.9% during the pandemic. Non-Hispanic White individuals, who showed the highest rates of current cigarette smoking (21.1%) during the pandemic, were the only racial/ethnic group showing a significant decline in the postpandemic period (19.8%). No significant changes were observed in the mean number of days or cigarettes smoked in the past 30 days, except for a marginally significant increase in cigarette consumption among non-Hispanic Black individuals.

Conclusions

These analyses suggest that the pandemic had a differential impact on the rates of current smoking across racial/ethnic subgroups in adults with chronic obstructive pulmonary disease and/or asthma, with a detrimental effect in Hispanic individuals and an improvement among non-Hispanic White individuals. Given the dangers of smoking in chronic lung conditions, future research should investigate the factors behind these to develop targeted interventions.

Single and multiple tobacco product use among people with disabilities: Findings from the National Health Interview Survey, 2019-2022

INTRODUCTION

People with disabilities, approximately 25 % of the population, have a higher prevalence of smoking cigarettes and using various tobacco products; however, little is known about multiple tobacco product (MTP) use among this population. This study assessed patterns of MTP use among people with disabilities.

METHODS

Data from the 2019-2022 National Health Interview Study were analyzed to estimate the prevalence of single tobacco, MTP, and specific combinations of MTP (multiple combusted, combusted and non-combusted) use among adults with any disability and six disability domains (cognitive, communication, hearing, mobility, self-care, vision). Multinomial logistic regression models examined the association between MTP use and disability status.

RESULTS

People with any disability had higher odds of single tobacco product use (aOR = 1.35; 95 % CI 1.26, 1.45) and MTP use (aOR = 1.81; 95 % CI 1.57, 2.09) compared to those without any disability, which included multiple combusted use (aOR = 2.01; 95 % CI 1.62, 2.51) and multiple combusted/non-combusted use (aOR = 1.70; 95 % CI 1.43, 2.02). Higher odds of multiple combusted use were also found among those with cognitive, hearing, mobility, and vision disabilities and higher odds of multiple combusted/non-combusted use were found among those with cognitive and vision disabilities compared to those without the respective disability.

CONCLUSION

People with disabilities have higher odds of MTP use and therefore may be exposed to more toxicants and at risk for more severe nicotine dependence than those without a disability. Future research should investigate reasons for MTP use in this population and tailored cessation interventions may need to account for MTP use.

Predictors of cigarette smoking and physical inactivity among teachers during the SARS-CoV-2 pandemic in Germany: a cross-sectional analysis of a nationwide online survey

Background

The SARS-CoV-2 pandemic significantly impacted professional and private lives, which influenced social and health-related behavior. Schools in particular were greatly affected as restrictions made teaching more challenging, leading to new stresses and additional workloads. Prior to the pandemic, teachers were already facing many physical and psychological stressors that were exacerbated by the pandemic. This may have resulted in a deterioration in the teachers' health behaviors. Therefore, the aim of this study was to examine the prevalence of cigarette smoking and physical activity among German teachers during the SARS-CoV-2 pandemic, to assess possible changes considering cigarette smoking and physical activity habits during the pandemic compared to the pre-pandemic period, and to identify predictors of teachers' cigarette smoking and physical inactivity during the pandemic.

Methods

In March 2021, a nationwide online survey was conducted among teachers in Germany. A total of 31,089 participants entered the analysis. Data on cigarette smoking and physical activity as well as sociodemographic, workplace-related, psychological, SARS-CoV-2-related, and health-related items were collected using established instruments and, if necessary, self-developed items. Two binary logistic regressions with stepwise inclusion of six different variable groups were performed to predict cigarette smoking and physical inactivity.

Results

Among all surveyed teachers, 13.9% reported smoking cigarettes, and 76.6% did not meet the physical activity recommendations. The regression analyses revealed 16 significant predictors of cigarette smoking and six significant predictors of physical inactivity.

Conclusions

The predictors revealed in the present study can help target interventions for teachers who are at higher risk for unhealthy behaviors during the SARS-CoV-2 pandemic and potential future pandemics. In particular, the alarming finding that more than three-quarters of teachers were physically inactive during the pandemic should place special emphasis on improving physical activity.

Virtual reality cue exposure as an add-on to smoking cessation group therapy: a randomized controlled trial

BACKGROUND

Cue exposure (CE) is used for relapse prevention as part of smoking cessation therapy to reduce the automatized response to smoking-related cues. Using CET in virtual reality (VR) is an approach to increase its efficacy by creating cost-efficient high-risk situations. The efficacy of VR-based CETs was compared to that of an unspecific relaxation intervention as an add-on to an established cognitive-behaviorally oriented smoking cessation group therapy (G-CBT).

METHODS

N = 246 abstinence-motivated smokers were included in a two-armed randomized controlled trial (G-CBT with VR-CET vs. G-CBT with progressive muscle relaxation/PMR) with 1-, 3-, and 6-month follow-ups (measurements in 2018-2020). All smokers joined a well-established G-CBT smoking cessation program with six sessions with four additional sessions of either VR-based smoking cue exposure therapy (VR-CET) or four sessions of group-based PMR. The primary outcome was abstinence after 6 months according to the Russell Standard; secondary outcomes included changes in the number of smoked cigarettes, craving (assessed by the Questionnaire of Smoking Urges/QSU), and self-efficacy (assessed by the Smoking Abstinence Self-Efficacy Scale/SES) over time.

RESULTS

Primary outcome: Six months after G-CBT, 24% of the participants were abstinent, and there was no significant difference between the PMR (n = 34/124) and VR-CET (n = 24/122) groups (odds ratio PMR/VR = 0.64). Secondary measures: SES increased, and QSU and the number of smoked cigarettes decreased over time. Baseline craving ratings predicted abstinence only in the VR-CET group.

CONCLUSION

This randomized controlled trial did not show increased abstinence rates related to smoking cue exposure in virtual reality. Secondary measures demonstrated significant reductions in craving and cigarette consumption as well as increases in self-efficacy over time, regardless of the intervention. However, high baseline craving was negatively related to abstinence in the VR-CET group, suggesting that intense craving was insufficiently addressed. This may indicate that the amount of training was insufficient and should be intensified. Individualization, e.g., adaptive, individualized approaches, is required to improve the effects of the VR-CET on smoking cessation in future studies.

Contextualizing Changes in e-Cigarette Use During the Early COVID-19 Pandemic and Accompanying Infodemic ("So Much Contradictory Evidence"): Qualitative Document Analysis of Reddit Forums

BACKGROUND

Understanding how social media platforms facilitate information exchange and influence behavior during health crises can enhance public health responses during times of uncertainty. While some risk factors for COVID-19 susceptibility and severity (eg, old age) were clear, whether e-cigarette use increased risk was not clear. People who used e-cigarettes had to navigate both the COVID-19 infodemic and a conflicting, politicized, and changing information environment about the interaction between COVID-19 and e-cigarette use.

OBJECTIVE

This study aims to characterize and contextualize e-cigarette-related behavior changes during the early COVID-19 pandemic and illuminate the role that social media played in decision-making.

METHODS

We conducted a qualitative analysis of COVID-19-related e-cigarette discussions on 3 Reddit forums about e-cigarettes. We collected 189 relevant discussion threads made in the first 6 months of the pandemic (collected from June 27, 2020, to July 3, 2020). Threads included 3155 total comments (mean 17 comments) from approximately 1200 unique Redditors. We developed and applied emergent codes related to e-cigarette perceptions and behaviors (eg, the role of nicotine in COVID-19 and do-it-yourself narratives) and web-based community interactions (eg, advice), identified thematic patterns across codes, and developed a model to synthesize the socioecological context of e-cigarette behaviors.

RESULTS

e-Cigarette subreddits provided a platform for Redditors to discuss perceptions and experiences with e-cigarettes, make sense of information, and provide emotional support. Discussions reflected an array of e-cigarette-related behavioral responses, including increases and decreases in use intensity, changes in purchasing practices (eg, stockpiling), and changes in vaping practices (eg, reusing disposable pods). This study presented a theoretically and empirically informed model of how circumstances created by the pandemic (eg, changes in activity space and product shortages) compelled behavior changes. Redditors drew from their existing perceptions, intentions, and experiences with nicotine and tobacco products; their personal pandemic experiences; and their participation on Reddit to decide whether and how to change their e-cigarette behaviors during the early pandemic. Forums reflected uncertainty, stress, and debate about the rapidly evolving and complicated public health information. Consumption and discussion of media (eg, news articles and peer-reviewed publications) on Reddit informed e-cigarette perceptions and behaviors. Decisions were complicated by distrust of the media.

CONCLUSIONS

Variations in individual traits and environmental circumstances during the early COVID-19 pandemic provide context for why there was no unified direction of e-cigarette behavior change during this period. Information and discussion on Reddit also informed risk perceptions and decisions during the pandemic. Social media is an effective and important place to communicate public health information, particularly during crisis or disaster situations. Moving forward, transparent, accurate, and specific message development should consider the stress, struggles, and stigma of people who use e-cigarettes and address the roles mistrust and misinformation play in decisions.

Impact of the COVID-19 Pandemic on the Management of Groin Hernia Repairs: A Nationwide Population-Based Study From the Swedish Hernia Register

Objective

The aim is to assess the impact of COVID-19 pandemic on delays in elective surgeries for symptomatic groin hernias in Sweden.

Background

In Sweden, over 16,000 groin hernia repairs are performed annually, primarily in elective daycare settings. The COVID-19 pandemic led to the temporary postponement of all elective surgeries to reallocate healthcare resources and limit viral transmission.

Methods

This nationwide population-based study utilizing data from the Swedish Hernia Register compared groin hernia repairs before (2015-2019) and during (2020-2021) the pandemic. Multivariable logistic regression analysis stratified by gender was employed for the outcomes. The main outcomes were risks of emergency repair, severe complications (Clavien-Dindo ≥3b), 30-day mortality, and reoperation for recurrence.

Results

A total of 109,459 groin hernia repairs (n = 98 156 in men and n = 11 303 in women) were analyzed. The number of elective repairs declined by 22.9%, while emergency repairs only increased by 2.2% in 2020. Women had a higher risk of emergency repair during the pandemic (odds ratio: 1.38, P < 0.001) and presented notably higher crude rates of 30-day mortality and bowel resection compared with men in both cohorts. However, the overall risks in the population remained stable despite these shifts.

Conclusions

"Watchful waiting" for symptomatic groin hernias due to postponement of elective repairs in men appears safe regarding the risks of emergency repair and severe complications, in contrary to women. While elective repairs can temporally be deferred during crises, careful consideration should be given to women. Given this large-scale study, watchful waiting may not be appropriate for women in future healthcare crises, warranting further investigations.

Did the pandemic change lifestyle behaviours in Italy? An interrupted time series analysis on the four main NCDs behavioural risk factors from 2008 to 2023

BACKGROUND

The COVID-19 pandemic has had repercussions in several areas. The indirect effects of the pandemic on healthy living behaviours are multiple and complex to assess. The aim is to assess the impact of the outbreak of COVID-19 pandemic in Italy on the most relevant modifiable behaviours risks for non-communicable diseases (NCDs).

METHODS

PASSI 2008-2023 data referring to a sample of 18-69-year-olds residing in Italy was used to estimate the prevalences of smoking, alcohol, fruit and vegetable consumption, and physical inactivity lifestyle. For each of these risks was used an interrupted time series (ITS) study with Generalized Least Squares (GLS) model to assess trends before and after the pandemic's outbreak in Italy (March 2020). The "intervention" period is postulated as March 2020, and the "post-intervention" period extends from April 2020 to December 2023. In these models, the hypothetical situation without "intervention" and with the trend remains unchanged is commonly known as the 'counterfactual' scenario. Through ITS model both "counterfactual data" and "factual data" were obtained.

RESULTS

From 2008 to 2023, 532,115 people were interviewed. Results showed, during "post-intervention" period, significant differences between factual and counterfactual prevalences started in 2022 and strengthened during 2023 and for all of the four behavioural indicators analysed: smoking, high-risk alcohol consumption, fruit and vegetable consumption (both all three of them worsening) and physical inactivity (which appears to decrease). Current smokers exhibited similar prevalences in March 2020 (24.5% vs. 24.3%), followed by a plateau throughout the entire 'post-intervention' period. By December 2023, however, the counterfactual prevalence was significantly lower than the observed rate (24.5% factual vs. 22.7% counterfactual). The initial improvement observed in the prevalence of high-risk drinkers in March 2020 (13% factual vs. 17% counterfactual) was followed by a rapid worsening and in December 2023 the prevalence was significantly higher than expected (19.7% vs. 16.9%). The fruit and vegetable consumption worsened and the factual prevalence of five-a-day in December 2023 was significantly lower than counterfactual (6.6% vs. 9.0%). Physical inactivity following an initial worsening in March 2020 (albeit not statistically significant), appeared to decrease in December 2023, with the factual prevalence lower than counterfactual (26.9% vs. 32.4%).

CONCLUSIONS

Results found in this article showed at the end of studied period the achievement of a plateau for current smokers, a worsening in the high-risk alcohol consumption, in fruit and vegetable intakes and a reduction in physical inactivity. Understanding shifts in these lifestyle indicators is crucial for the proper design of interventions aimed at reducing the burden of NCDs.

Analysis of lung cancer incidence, mortality trends, and smoking rates in Japan:1975-2022 with insights on the impact of COVID-19

In Japan, high-quality cancer statistics are collected through cancer registries. However, these data are rarely summarized or reported in research articles. We compiled statistical data on lung cancer in Japan including the COVID-19 pandemic. In 2019, the number of cases of lung cancer in Japan was 126,548. The age-adjusted incidence rate of lung cancer increased from 23.2/100,000 to 42.4/100,000 in males and from 7.2/100,000 to 18.3/100,000 in females between 1975 and 2019. The age-adjusted mortality rate of lung cancer in Japan increased since 2000, after which it decreased. This trend was similar in both males and females. We also investigated statistics on lung cancer worldwide (Australia, Sweden, England, and the United States [USA]). The age-adjusted incidence rate of lung cancer in the data standardized to the world population for males has increased only in Japan; for females, it has decreased only in the USA. Global age-adjusted lung cancer mortality rates have been declining in all countries. In addition, the COVID-19 pandemic has not affected the age-adjusted mortality rate of lung cancer. On the other hand, the number of individuals undergoing lung cancer screening in Japan decreased from 7.92 million in 2019 to 6.59 million in 2020. The COVID-19 pandemic may have affected individuals undergoing lung cancer screening, and its impact on lung cancer needs to be continuously monitored in the future.

Smoking Status in Pregnancy: A Retrospective Analysis in Northern Greece

Background and Objectives: Smoking has adverse effects on both maternal and fetal health and its incidence varies among different countries. The aim of this study was to identify the prevalence of smoking during pregnancy and to identify factors associated with smoking. Materials and Methods: This was a retrospective study conducted at the Third Department of Obstetrics and Gynecology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Greece, during an 11-year period (2013-2023). All women receiving antenatal care in our unit were eligible to participate when they attended the prenatal unit for the first trimester nuchal translucency scan (11+0-13+6 weeks). Results: Of the 12,074 pregnant women included in the study, 5005 (41.5%) reported themselves as smokers before pregnancy; the smoking cessation rate due to pregnancy was 70.2% (3516/5005) and the prevalence of smoking in pregnancy was 12.3% (1489/12,074). Multiparity was associated with less odds of smoking before pregnancy (OR: 0.79; 95% CI: 0.73-0.85), whereas advanced maternal age (OR: 1.17; 95% CI: 1.07-1.27) and obesity (OR: 1.44; 95% CI: 1.29-1.6) were associated with higher odds of smoking before pregnancy. Smoking prevalence in pregnancy was lower in women that conceived via assisted reproductive techniques (ARTs) (OR: 0.52; 95% CI: 0.38-0.70) and higher in cases of multiparity (OR: 1.12; 95% CI: 1.008-1.26) and maternal obesity (OR: 1.55; 95% CI: 1.20-2.00). Conception via ARTs was associated with higher odds of smoking cessation (OR: 1.9; 95% CI: 1.38-2.69), whereas multiparous (OR: 0.7; 95% CI: 0.62-0.8) and obese women (OR: 0.72; 95% CI: 0.61-0.85) were less likely to quit smoking. Conclusions: Pregnancy is a strong motivator for women to quit smoking, especially in primiparous women and those undergoing ARTs. Our findings highlight the need for more consistent smoking prevention and health promotion strategies in Greece as a very high proportion of women smoke before pregnancy and a substantial proportion continue in pregnancy.

Influence of the home smoking environment and stress on smoking behaviors during the COVID-19 pandemic among patients of federally qualified health centers in rural Georgia

INTRODUCTION

The COVID-19 pandemic caused major stress, as well as changes to home and work environments, with the potential to alter smoking-related behaviors. This study examined determinants of smoking-related behaviors among patients of federally qualified health centers (FQHCs) in Georgia.

METHODS

We analyzed survey data from 353 patients (mean age=50 years, 62.9% women, 54.4% Black/African American, 27.8%

RESULTS

Most study participants (85.6%) smoked daily, and 41.6% had smoke-free homes. Compared to pre-pandemic, 36.3% reported increased stress, 28.8% increased smoking, 18.8% increased in-home smoking, and 55.4% quit attempts. Regression models showed more household members who smoke (AOR=1.56; 95% CI: 1.02-2.39) and greater stress (AOR=5.52; 95% CI: 2.74-11.12) were associated with increased smoking (vs no change) since the pandemic began. Non-daily (vs daily) smoking (OR=4.79; 95% CI: 1.71-13.46) was associated with decreased smoking (vs no change). Allowing smoking in the home and greater stress were associated with both increased and decreased in-home smoking (vs no change). We found no associations with quit attempts.

CONCLUSIONS

Home environments, specifically home smoking restrictions, as well as stress, may be important intervention targets during societal stressors.

Change in prevalence of smoking during the first year of the COVID-19 pandemic among middle-aged and older adults in Canada: a cohort study of the Canadian Longitudinal Study on Aging

Objective

The primary objective was to evaluate the change in the prevalence of daily or occasional tobacco smoking during the first year of the COVID-19 pandemic and to assess if socioeconomic factors were associated with changes in smoking. The secondary objective was to evaluate the association of smoking with adherence to public health measures.

Methods

In this prospective cohort study, using Canadian Longitudinal Study on Aging data (44 139 middle-aged and older-aged adults), the prevalence of smoking during the COVID-19 pandemic (2020) and prepandemic (2011-2018) was estimated using weighted generalised estimating equations. ORs and 95% CIs for the association between smoking and adherence to public health measures (a derived score) were estimated using multinomial logistic regression.

Results

Time (during vs prepandemic) was a significant predictor of smoking (adjusted OR (aOR) 1.12; 95% CI 1.07, 1.17). The adjusted prevalence of smoking during the beginning of the pandemic was 11.2% (95% CI 10.1%, 12.4%), compared with the prepandemic prevalence of 10.1% (95% CI 9.1%, 11.2%), with p<0.001. Factors associated with an increase in smoking were male sex, being aged 55 to 74 years, residing in Ontario or British Columbia, immigrant background, belonging to a racialised group, higher income and being married/common-law relationship. Smoking was associated with increased odds of high adherence to public health measures (aOR 1.53; 95% CI 1.31, 1.78).

Conclusion

Among middle-aged and older adults in Canada, there was a small increase in the adjusted prevalence of smoking early in the pandemic. Daily or occasional smoking was associated with greater adherence to public health measures.

Prevalence, demographic, socio-economic, and lifestyle factors associated with cigarette, e-cigarette, and dual use: evidence from the 2017-2021 Scottish Health Survey

Understanding the correlation between demographic, socio-economic, and lifestyle factors with e-cigarette use, cigarette smoking, and dual use is essential for targeted public health interventions. This study examines the prevalence of these behaviors in Scotland and identifies the associated factors. We conducted a repeated cross-sectional analysis of the Scottish Health Survey data from 2017 to 2021, leveraging data from 12,644 participants aged 16 and older: 2271 cigarette smokers, 687 e-cigarette users, 428 dual users, and 9258 never users. Weighted prevalences were calculated by age group, sex, and survey year, followed by weighted multinomial logistic regression to explore associated factors. The overall prevalences were 72.0% (95% CI 70.9-73.1) for never users, 18.9% (95% CI 17.9-19.9) for cigarette smokers, 5.5% (95% CI 5.0-6.1) for e-cigarette users, and 3.6% (95% CI 3.2-4.0) for dual users. From 2017 to 2021, cigarette smoking declined from 21.7% (95% CI 19.6-23.9) to 13.1% (95% CI 11.5-15.0), e-cigarette use from 6.5% (95% CI 5.4-7.8) to 4.8% (95% CI 3.6-6.4), and dual use from 3.7% (95% CI 2.9-4.6) to 2.7% (95% CI 1.9-3.7). Age was a critical factor, with the 25-34 age group more likely to use e-cigarettes (p = 0.007) and the 35-44 age group more likely to engage in dual use (p = 0.006) compared to the 16-24 age group. Males had higher odds of e-cigarette use than females (p = 0.031). White individuals had higher odds of using e-cigarettes (p = 0.023) and being dual users (p = 0.017) compared to non-whites. Previously married individuals had higher odds of dual use than singles (p = 0.031). Larger household sizes were linked to reduced odds of all three behaviors (p = 0.001). Rural residents were less likely to use e-cigarettes compared to urban residents (p = 0.025). Higher education correlated with lower odds of all three behaviors (p = 0.001). Manual occupation increased the likelihood of dual use (p = 0.042). Lower income and higher deprivation significantly increased the odds of all three behaviors (p < 0.001). Excessive alcohol consumption was associated with increased odds of the three behaviors (p < 0.001). Poor sleep quality correlated with increased odds of dual use (p = 0.002) and cigarette smoking (p < 0.001). Adherence to physical activity guidelines was associated with reduced odds of all three behaviors (cigarette smoking p < 0.001, e-cigarette use p = 0.031, dual use p = 0.016). In conclusion, this study showed a decline in the prevalence of cigarette smoking, e-cigarette use, and dual usage from 2017 to 2021 in Scotland. Significant associations with demographic, socio-economic, and lifestyle factors highlight the need for targeted public health interventions.

Effects of changes in daily life attributed to COVID-19 on allergic diseases among Korean adolescents

OBJECTIVE

The daily lives of adolescents have changed significantly because of COVID-19 pandemic. We investigated the effects of changes in daily life attributed to COVID-19 on allergic diseases among Korean adolescents.

METHODS

Data from the 2021 Korea Youth Risk Behavior Survey were used. In total, 54,848 survey participants were included in the analysis. Allergic diseases included allergic rhinitis, atopic dermatitis, and asthma. Changes attributed to COVID-19 included family economic difficulties, physical activity, breakfast skipping frequency, alcohol consumption, smoking, and depressive moods. Chi-square tests and multiple logistic regression analyses were conducted to examine the impact of changes in daily life attributed to COVID-19 on allergic diseases.

RESULTS

Among the Korean adolescents surveyed, 29.8% experienced a deterioration in their economic status due to COVID-19, 49.1% reported decreased physical activity, 2.8% reported increased alcohol consumption, 1.0% reported an increase in their smoking behavior, and 36.9% reported an increase in depressive moods. Those diagnosed with atopic dermatitis, allergic rhinitis, or asthma within the previous 12 months accounted for 17.1%, 6.2%, and 1.0% of the population, respectively. Adolescents who were significantly affected by COVID-19 in their daily lives were frequently diagnosed with allergic diseases within the last 12 months.

CONCLUSION

Changes in daily life due to COVID-19, including decreased physical activity and increased depressive mood, were common in adolescents and were associated with an increased prevalence of allergic diseases. Since changes in daily life due to the pandemic may increase the burden of allergic disease, additional interventions for disease management should be considered.

COVID-19 pandemic, pregnancy care, perinatal outcomes in Eastern Myanmar and North-Western Thailand: a retrospective marginalised population cohort

BACKGROUND

The COVID-19 pandemic disrupted routine health care and antenatal and birth services globally. The Shoklo Malaria Research Unit (SMRU) based at the Thailand-Myanmar border provides cross border antenatal care (ANC) and birth services to marginalised pregnant women. The border between the countries entered lockdown in March 2020 preventing cross-border access for women from Myanmar to Thailand. SMRU adapted by opening a new clinic during the COVID-19 pandemic in Myanmar. This study explored the impact of the COVID-19 pandemic and response on access to ANC and pregnancy outcomes for marginalised pregnant women in the border regions between Thailand and Myanmar.

METHODS

A retrospective review of medical records of all pregnancies delivered or followed at antenatal clinics of the SMRU from 2017 to the end of 2022. Logistic regression was done to compare the odds of maternal and neonatal outcomes between women who delivered pre-COVID (2017-2019) and women who delivered in the COVID-19 pandemic (2020-2022), grouped by reported country of residence: Thailand or Myanmar.

RESULTS

Between 2017 and the end of 2022, there were 13,865 (5,576 resident in Thailand and 8,276 in Myanmar) marginalised pregnant women who followed ANC or gave birth at SMRU clinics. Outcomes of pregnancy were known for 9,748 women with an EGA ≥ 28 weeks. Unknown outcome of pregnancy among women living in Thailand did not increase during the pandemic. However, there was a high (60%) but transient increase in unknown outcome of pregnancy for women with Myanmar residence in March 2020 following border closure and decreasing back to the baseline of 20-30% after establishment of a new clinic. Non-literate women were more likely to have an unknown outcome during the pandemic. There was no statistically significant increase in known stillbirths or maternal deaths during the COVID pandemic in this population but homebirth was over represented in maternal and perinatal mortality.

CONCLUSION

Decreasing barriers to healthcare for marginalised pregnant women on the Thailand-Myanmar border by establishment of a new clinic was possible in response to sudden border closure during the COVID-19 pandemic and most likely preventing an increase in maternal and perinatal mortality.

Health behaviour and wellbeing trends among Australian adults before and during the COVID-19 pandemic (2017-2022): An interrupted time-series analysis

Objective

To explore population-level trends in health behaviours and wellbeing indicators from before (2017-2019) to during (2020-2022) the COVID-19 pandemic in Australia.

Methods

Using cross-sectional data from New South Wales Adult Population Health Surveys (2017-2022, n = 73,680 responses), we calculated weighted prevalence estimates and interrupted time-series logit models to investigate trends in health behavioural risk factors (vegetable and fruit intake, physical activity, alcohol consumption, smoking, e-cigarette use), Body Mass Index (BMI) (overweight and obesity), and wellbeing indicators (psychological distress, self-rated health) among adults aged ≥ 16 years before and during the pandemic.

Results

From 2017 to 2022, the behavioural risk factors and BMI trends were mostly unchanged. Similarly, wellbeing indicator trends showed only minor variations according to age. The interrupted time-series models found marked changes from before to during the COVID-19 pandemic for e-cigarette use and self-rated health. E-cigarette use showed an overall increasing trend, with significant increases from 2017 to 2022 (OR 8.25, 95 %CI 6.10-11.16). Poor self-rated health showed a stable trend before COVID-19, but decreased in 2020 (OR 0.68, 95 %CI 0.58-0.80) and 2021 (OR 0.70, 95 %CI 0.60-0.81), returning to pre-COVID levels in 2022 (OR 1.23, 95 %CI 1.07-1.41). During the pandemic (2020-2022), there were few statistically significant observed changes in prevalence trends according to SES indicators.

Conclusion

Among Australian adults, relatively small population-level impacts of the COVID-19 pandemic on health behaviours and wellbeing trends were observed. Continued surveillance and sub-group analyses are essential for investigating potential time-lagged effects and regional or sociodemographic differences in health behaviours and wellbeing.

Effect of COVID-19 pandemic on bioimpedance health indicators in young adults

OBJECTIVES

Herein, we investigate the relationships between the COVID-19 pandemic and overcoming the virus, and its effects on body composition parameters in young adults from Slovakia.

METHODS

We assessed 773 adults aged 18 to 30 years in pandemic-status sub-groups. Individual lifestyles and overcoming the COVID-19 effects were evaluated by a detailed questionnaire, and body composition parameters were analyzed using the InBody 770 bioimpedance analyzer.

RESULTS

Statistically significant lower values were observed in the male group during the pandemic for the following parameters; proteins and minerals, fat free mass (FFM), skeletal muscle mass (SMM), lean body mass (LBM) and its values in the right and left arm and trunk, total body water (TBW) and its values in the right and left arm and trunk, body cell mass (BCM), basal metabolic rate (BMR) and phase angle (PA). The regression analysis confirmed the negative pandemic effect and the negative impact of COVID-19 on men in the following parameters: proteins (p = .027 for pandemic and p = .005 for COVID-19), FFM (p = .023 for pandemic and p = .005 for COVID-19), LBM (p = .022 for pandemic and p = .004 for COVID-19), SMM (p = .028 for pandemic and p = .005 for COVID-19), TBW (p = .020 for pandemic and p = .004 for COVID-19), BMR (p = .024 for pandemic and p = .005 for COVID-19) and PA (p = .009 for pandemic). Physical activity was a further significant predictor in men for all the above parameters.

CONCLUSIONS

We observed significantly lower body composition parameters associated with fat free mass in young adult men during the pandemic than before it. However, future research is warranted to determine if these effects have long-term significance.

An Estimation of the Prevalence of Smoking and e-Cigarette Use among U.S. Adults If Menthol Cigarettes and Flavored Cigars Are Banned

INTRODUCTION

People's reaction to the FDA's ban on flavored cigarettes and cigars may be modified by a concurrent ban on flavored e-cigarettes. We aim to estimate the prevalence of smoking and e-cigarette use among U.S. adults under various ban scenarios.

METHODS

We collected the reactions of people who used cigarettes, cigars, and e-cigarettes reactions to three hypothetical ban scenarios, (1) restricting menthol cigarettes and flavored cigars only, or (2) further restricting e-cigarettes with any flavors except menthol or tobacco, or (3) further restricting e-cigarettes with all flavors. The above data were analyzed to identify determinants of reactions and to estimate and calibrate the probabilities of quitting and switching to non-flavored cigarettes and cigars. Afterward, the probabilities were applied to 2018-2019 TUS-CPS respondents to estimate the prevalence of smoking and e-cigarette use.

RESULTS

Compared with the baseline, the prevalence of smoking decreased from 12.6% to 10.5%, and e-cigarette use increased from 2.6% to 3.8% in Scenario No.1. In Scenario No.2 and No.3, the prevalence of smoking was 10.5% and 10.7%, and the prevalence of e-cigarette use were 3.1% and 2.4%, respectively. For black people, the prevalence of smoking decreased from 14.2% in baseline to 8.1%-8.8% in three scenarios.

CONCLUSIONS

The result indicated that for a ban on menthol cigarettes and flavored cigars, a concurrent ban on flavored e-cigarettes with an exemption of menthol flavor could be more effective in encouraging people to quit smoking. Black people may see a disproportionate benefit from all ban scenarios compared with other race/ethics groups.

Dual and poly-nicotine and tobacco use among adolescents in the United States from 2011 to 2022

BACKGROUND

Adolescent nicotine and tobacco product use remains common despite declining smoking rates in the United States, likely due to the emergence of novel products. Concurrent use of multiple products may increase the risk of nicotine dependency and subsequent substance use.

AIM

To identify patterns and trends of dual and poly nicotine and tobacco use among adolescents in the US and explore associations of dual and poly nicotine and tobacco use with sociodemographic factors.

METHODS

12 years of annual National Youth Tobacco Survey data (2011-2022) from 242,637 respondents were used to examine prevalence trends of different combinations of nicotine or tobacco product use among adolescents in the US using weighted point estimates for each year. Poisson regression models examined sociodemographic factors associated with different patterns of dual and poly-product use from 2011 to 2022.

RESULTS

Overall, the prevalence of dual (i.e. at least two products) and poly (i.e. at least three products) use decreased between 2011 and 2021 (from 9.5 % to 2.8 % and from 5.1 % to 1.1 %, respectively), but showed signs of increase between 2021 and 2022 (3.7 % for dual and 1.7 % for poly use). The most common combinations included a combustible product with either a novel or noncombustible product. The risk for dual and poly-product use was higher among non-Hispanic Whites, males, and high school students.

CONCLUSIONS

Previously declining trends in the prevalence of tobacco/nicotine dual and poly use may have been reversed. Close monitoring and targeted tobacco control policies are essential to tackle multiple product use among adolescents.

Risk factors for smoking in adolescence: evidence from a cross-sectional survey in Switzerland

BACKGROUND

Cigarette smoking during adolescence is a major public health concern with far-reaching health implications. Adolescents who smoke are at an increased risk of developing long-term health problems and are more likely to continue smoking into adulthood. Therefore, it is vital to identify and understand the risk factors that contribute to adolescent smoking - which in turn facilitate the development of targeted prevention and intervention programs.

METHODS

Data was drawn from a cross-sectional survey conducted between October and December 2021, encompassing adolescents of adolescents aged 14 to 19 residing in Switzerland (n = 2,683). Multiple logistic regression analysis was employed to explore which demographic, household, behavioural and psychographic factors are associated with current smoking status.

RESULTS

The regression results showed higher odds of smoking for female respondents (OR 1.39; p-value 0.007); older adolescents (OR 1.30; p-value < 0.001); those living in the French-speaking part of Switzerland (OR 1.39; p-value 0.021), in suburban areas (OR 1.35; p-value 0.023) and with a smoker in the same household (OR 2.41; p-value < 0.001); adolescents consuming alcohol (OR 4.10; p-value < 0.001), cannabis products (OR 6.72; p-value < 0.001) and hookah (OR 5.07; p-value < 0.001) at least once a month; respondents not engaging in sports (OR 1.90; p-value < 0.001) or music (OR 1.42; p-value 0.031) as top five leisure activities and those experiencing high stress levels at home (OR 1.74; p-value < 0.001). Adolescents with high scores in health awareness (OR 0.33; p-value < 0.001), on the relational self-esteem scale (OR 0.78; p-value 0.054) and on the general well-being scale (OR 0.52; p-value 0.022) were less likely to smoke than their counterparts with lower scores. High risk-seeking was associated with higher odds of smoking (OR 2.15; p-value < 0.001).

CONCLUSIONS

Our results suggest the importance of a comprehensive approach at both individual and institutional levels to reduce smoking rates in adolescents. More specifically, a holistic strategy that encompasses adolescents, families, schools and policymakers ranging from strengthening adolescents' self-esteem, smoking cessation support for parents, to increasing engagement in musical and physical activities, and enhancing health awareness in the school curriculum.

Geographical differences in the financial impacts of different forms of tobacco licence fees on small retailers in Scotland

OBJECTIVE

Retailer licencing fees are a promising avenue to regulate tobacco availability. However, they face strong opposition from retailers and the tobacco industry, who argue significant financial impacts. This study compares the impacts of different forms of tobacco licence schemes on retailers' profits in Scotland.

METHODS

We calculated gross profits from tobacco sales in 179 convenience stores across Scotland using 1 099 697 electronic point-of-sale records from 16 weeks between 2019 and 2022. We estimated different fees using universal, volumetric and separate urban/rural schemes. We identified the point at which 50% of retailers would no longer make a gross profit on tobacco sales for each scheme and modelled the financial impact of 10 incremental fee levels. The financial impact was assessed based on changes in retailers' tobacco gross profits. Differences by neighbourhood deprivation and urban/rural status were examined.

RESULTS

The gross profit from tobacco per convenience store averaged £15 859/year. Profits were 2.29 times higher in urban (vs rural) areas and 1.59 times higher in high-deprivation (vs low-deprivation) areas, attributable to higher sales volumes. Tobacco gross profit decreased proportionally with increasing fee levels. Universal and urban/rural fees had greater gross profit reductions in rural and/or less deprived areas, where profits were lower, compared with volumetric fees.

CONCLUSION

The introduction of tobacco licence fees offers a potential opportunity for reducing the availability of tobacco retailers. The likely impact of a tobacco licence fee is sensitive to the type of licence scheme implemented, the level at which fees are set and the retailers' location in relation to neighbourhood deprivation and rurality.

The association of psychological distress and economic and health worries with tobacco smoking behavior during the COVID-19 pandemic: a two-year longitudinal cohort study

BACKGROUND

The COVID-19 pandemic and other life events may trigger worries and psychological distress. These impacts may lead to unhealthy behaviors, such as tobacco smoking, but the degree of such associations is unclear. The current three-wave longitudinal study examines changes in tobacco smoking in Norway between 2020 and 2022 and their associations with psychological distress as well as health- and economy-related worries.

METHODS

Data were collected in April 2020 (baseline), January 2021, and January 2022 in Bergen, Norway, from an online longitudinal population-based survey. Smoking tobacco (the outcome variable) was dichotomized based on the responses to the question of whether participants smoked cigarettes or not. Tobacco smoking and its associations with psychological distress were assessed among 24,914 participants (response rate 36%) in a mixed model regression presented with coefficients and 95% confidence intervals (CI), adjusting for COVID-19-related worries, home office/study, occupational situation, age, gender, education, having children below 18 years living at home, living alone, and alcohol consumption.

RESULTS

A total of 10% of the study sample were current smokers at baseline. At baseline, smoking tobacco was associated with high levels of psychological distress (absolute difference 13%, 95% CI 10%; 15%), advanced age (50-59 years: 11%, CI 10%; 13%), and hazardous alcohol use (4%, CI 3%; 5%) compared to their counterparts. Higher education (-5%, CI -6%; -4%), working from home (-4%, CI -5%; -4%), and higher physical activity levels (-4%, CI -5%; -3%) were associated with non-smoking. The prevalence of smoking among individuals experiencing severe psychological distress decreased slightly over time (-2% per year, CI -3%; -1%).

CONCLUSIONS

Smoking was associated with severe psychological distress, advanced age, and hazardous alcohol use at baseline; non-smoking was associated with high education, working from home, and high physical activity. Nevertheless, the smoking rate among individuals experiencing severe psychological distress slightly decreased over the course of the COVID-19 pandemic.

Tobacco and marijuana use during the COVID-19 pandemic lockdown among American Indians residing in California and Oklahoma

INTRODUCTION

American Indian (AI) people experience a disproportionate tobacco and marijuana burden which may have been exacerbated by the COVID-19 pandemic. Little is known about the tobacco and marijuana habits of American Indian individuals during the COVID-19 pandemic. The objective of this study is to examine tobacco and marijuana use as well as change in use during the COVID-19 pandemic among the American Indian community.

METHODS

This cross-sectional study analyzes survey data from a convenience sample of American Indian individuals residing in California and Oklahoma and included adults with and without cancer that resided in both rural and urban areas (n=1068).

RESULTS

During October 2020 - January 2021, 36.0% of participants reported current use of tobacco products, 9.9% reported current use of marijuana products, and 23.7% reported increased use of tobacco and/or marijuana in the past 30 days, with no difference between those with cancer and those without cancer. Tobacco use was associated with marital status, age, employment status, COVID-19 exposure, COVID-19 beliefs, and alcohol consumption. Marijuana use was associated with COVID-19 beliefs, alcohol consumption, and income level. Increased tobacco and/or marijuana use was associated with baseline use of those products. Nearly a quarter of participants reported increased use of tobacco and/or marijuana products during the COVID-19 pandemic.

CONCLUSIONS

We observed high rates of tobacco use during the COVID-19 pandemic, consistent with other studies. Research is needed to examine whether tobacco and marijuana use will decrease to pre-pandemic levels post-pandemic or if these behaviors will persist post-pandemic. Given these findings, there is a pressing need to increase access to evidence-based tobacco and marijuana treatment services in the AI population post COVID-19 pandemic.

Trends and Associations of Past-30-Day Cigar Smoking in the U.S. by Age, Race/Ethnicity, and Sex, NSDUH 2002-2020

Cigar smoking remains a public health issue in the United States (U.S.), with a heterogeneous prevalence based on sociodemographic characteristics. Nationally representative data suggest changes in cigar smoking over time, with some evidence for sociodemographic differences. Using data from the 2002-2019 National Survey on Drug Use and Health (NSDUH), the prevalence of past-30-day cigar smoking was examined overall and stratified by sociodemographic characteristics; joinpoint regression examined the trends. Logistic regression analyses identified the correlates of cigar smoking using 2020 NSDUH data. From 2002 to 2004, the prevalence of cigar smoking remained stable (5.33-5.73%), but declined from 2004 to 2019 (5.73-4.29%). Cigar smoking declined in some periods between 2002-2019 among the non-Hispanic White, Hispanic, ages 12-17, ages 18-20, ages 21-25, age ≥ 35, and male subgroups, but remained unchanged among the non-Hispanic Other, ages 26-34, and female subgroups. Cigar smoking increased among non-Hispanic Black persons overall from 2002 to 2019 (6.67-8.02%). Past-30-day cigarette smoking and drug or alcohol use disorder was associated with an increased likelihood of cigar use, while female sex was associated with a decreased likelihood of cigar use, across all age groups. Though a decline in the prevalence of past-30-day cigar smoking is seen in the general population, the same is not evident among all sociodemographic subgroups. Our findings have the potential to inform tobacco cessation efforts within clinical practice, as well as regulatory efforts to reduce cigar use.

Cytisine Versus Varenicline for Smoking Cessation in a Primary Care Setting: A Randomized Non-inferiority Trial

INTRODUCTION

A smoking-cessation program was implemented as a randomized non-inferiority trial in primary care practices in Croatia and Slovenia to investigate whether a standard 4-week treatment with cytisine was at least as effective and feasible as a standard 12-week treatment with varenicline in helping smokers quit.

AIMS AND METHODS

Out of 982 surveyed smokers, 377 were recruited to the non-inferiority trial: 186 were randomly assigned to cytisine and 191 to varenicline treatment. The primary cessation outcome was 7-day abstinence after 24 weeks, while the primary feasibility outcome was defined by adherence to the treatment plan. We also compared the rates of adverse events between the two treatment groups.

RESULTS

The cessation rate after 24 weeks was 32.46% (62/191) in the varenicline group and 23.12% (43/186) in the cytisine group (odds ratio [OR]: 95%, credible interval [CI]: 0.39 to 0.98). Of 191 participants assigned to varenicline treatment 59.16% (113) were adherent, while 70.43% (131 of 186) were adherent in the cytisine group (OR: 1.65, 95% CI: 1.07 to 2.56). Participants assigned to cytisine experienced fewer total (incidence rate ratio [IRR]: 0.59, 95% CI: 0.43 to 0.81) and fewer severe or more extreme adverse events (IRR: 0.72, 95% CI: 0.35 to 1.47).

CONCLUSIONS

This randomized non-inferiority trial (n = 377) found the standard 4-week cytisine treatment to be less effective than the standard 12-week varenicline treatment for smoking cessation. However, adherence to the treatment plan, ie, feasibility, was higher, and the rate of adverse events was lower among participants assigned to cytisine treatment.

IMPLICATIONS

The present study found the standard 12 weeks of varenicline treatment to be more effective than the standard 4 weeks of cytisine treatment for smoking cessation in a primary care setting in Croatia and Slovenia. Participants assigned to cytisine, however, had a higher adherence to the treatment plan and a lower rate of adverse events. Estimates from the present study may be especially suitable for generalizations to high-smoking prevalence populations in Europe. Given the much lower cost of cytisine treatment, its lower rate of adverse events, and higher feasibility (but its likely lower effectiveness with the standard dosage regimen), future analyses should assess the cost-effectiveness of the two treatments for health policy considerations.

Risk perceptions and changes in tobacco use in relation to Coronavirus Disease 2019 pandemic: A qualitative study on adolescent tobacco users in Hong Kong

INTRODUCTION

Tobacco use is associated with an increased risk of Coronavirus Disease 2019 (COVID-19) infection, severe COVID-19 outcomes requiring intensive care, and mortality. We investigated the perceived risk of and changes in cigarette, e-cigarette (EC) and heated tobacco product (HTP) use in relation to COVID-19 in Hong Kong adolescent tobacco users.

METHODS

We conducted semi-structured telephone interviews from January to April 2021 and in February 2022 on 40 adolescents (65% boys, Secondary school grades 2-6) who participated in our previous smoking surveys and were using cigarettes, ECs or HTPs before the first wave of the COVID-19 pandemic in January 2020.

RESULTS

Adolescents generally perceived higher risks of contracting and having more severe COVID-19 from using cigarettes than ECs/HTPs, but they had limited knowledge of COVID-19 risks from EC/HTP use, particularly. Both increased and reduced consumption were found in tobacco, with EC use being the less affected product. Changes also included switching to ECs for convenience and lower cost and shifting from smoking cigarettes outside to mainly at home or in hidden areas. COVID-related policies, fear of infection, non-COVID-related health concerns, less social opportunities and pocket money, and limited access to tobacco products were barriers to tobacco use. In contrast, greater freedom at home versus school and negative emotions due to social distancing were facilitators. Family/peer influence had mixed impacts.

CONCLUSIONS

Adolescent tobacco users perceived lower COVID risks associated with HTPs and ECs than cigarettes, and various changes in tobacco use were found amid the pandemic in Hong Kong. COVID-19 and related social changes may both facilitate or deter adolescent tobacco use.

Implementation of ask-advise-connect for smoking cessation in Dutch general practice during the COVID-19 pandemic: a mixed-methods evaluation using the CFIR framework

BACKGROUND

The Ask-Advise-Connect (AAC) approach can help primary care providers to increase the number of people who attempt to quit smoking and enrol into cessation counselling. We implemented AAC in Dutch general practice during the COVID-19 pandemic. In this study we describe how AAC was received in Dutch general practice and assess which factors played a role in the implementation.

METHODS

A mixed-methods approach was used to evaluate the implementation of AAC. Implementation took place between late 2020 and early 2022 among 106 Dutch primary care providers (general practitioners (GPs), practice nurses and doctor's assistants). Quantitative and qualitative data were collected through four online questionnaires. A descriptive analysis was conducted on the quantitative data. The qualitative data (consisting of answers to open-ended questions) were inductively analysed using axial codes. The Consolidated Framework for Implementation Research was used to structure and interpret findings.

RESULTS

During the study, most participants felt motivated (84-92%) and able (80-94%) to apply AAC. At the end of the study, most participants reported that the AAC approach is easy to apply (89%) and provides advantages (74%). Routine implementation of the approach was, however, experienced to be difficult. More GPs (30-48%) experienced barriers in the implementation compared to practice nurses and doctor's assistants (7-9%). The qualitative analysis showed that especially external factors, such as a lack of time or priority to discuss smoking due to the COVID-19 pandemic, negatively influenced implementation of AAC.

CONCLUSIONS

Although AAC was mostly positively received in Dutch general practice, implementation turned out to be challenging, especially for GPs. Lack of time to discuss smoking was a major barrier in the implementation. Future efforts should focus on providing additional implementation support to GPs, for example with the use of e-health.

Smoking cessation and vaccination

A significant proportion of COPD patients (∼40%) continue smoking despite knowing that they have the disease. Smokers with COPD exhibit higher levels of nicotine dependence, and have lower self-efficacy and self-esteem, which affects their ability to quit smoking. Treatment should be adapted to the needs of individual patients with different levels of tobacco dependence. The combination of counselling plus pharmacotherapy is the most effective cessation treatment for COPD. In patients with severe COPD, varenicline and bupropion have been shown to have the highest abstinence rates compared with nicotine replacement therapy. There is a lack of evidence to support that smoking cessation reduction or harm reduction strategies have benefits in COPD patients. The long-term efficacy and safety of electronic cigarettes for smoking cessation need to be evaluated in high-risk populations; therefore, it is not possible to recommend their use for smoking cessation in COPD. Future studies with the new generation of nicotine vaccines are necessary to determine their effectiveness in smokers in general and in COPD patients.

Unintended Consequences of COVID-19 Non-Pharmaceutical Interventions (NPIs) for Population Health and Health Inequalities

Since the start of the COVID-19 pandemic in early 2020, governments around the world have adopted an array of measures intended to control the transmission of the SARS-CoV-2 virus, using both pharmaceutical and non-pharmaceutical interventions (NPIs). NPIs are public health interventions that do not rely on vaccines or medicines and include policies such as lockdowns, stay-at-home orders, school closures, and travel restrictions. Although the intention was to slow viral transmission, emerging research indicates that these NPIs have also had unintended consequences for other aspects of public health. Hence, we conducted a narrative review of studies investigating these unintended consequences of NPIs, with a particular emphasis on mental health and on lifestyle risk factors for non-communicable diseases (NCD): physical activity (PA), overweight and obesity, alcohol consumption, and tobacco smoking. We reviewed the scientific literature using combinations of search terms such as 'COVID-19', 'pandemic', 'lockdowns', 'mental health', 'physical activity', and 'obesity'. NPIs were found to have considerable adverse consequences for mental health, physical activity, and overweight and obesity. The impacts on alcohol and tobacco consumption varied greatly within and between studies. The variability in consequences for different groups implies increased health inequalities by age, sex/gender, socioeconomic status, pre-existing lifestyle, and place of residence. In conclusion, a proper assessment of the use of NPIs in attempts to control the spread of the pandemic should be weighed against the potential adverse impacts on other aspects of public health. Our findings should also be of relevance for future pandemic preparedness and pandemic response teams.
