Context Matters: Patterns in Physical Distancing Behavior Across Situations and Over Time During the Covid-19 Pandemic in the Netherlands.

BACKGROUND: Physical distancing is an effective preventative measure during respiratory infectious disease outbreaks. Prior studies on distancing behaviors have largely ignored context characteristics (physical, social) and time. PURPOSE: We investigated patterns in physical distancing over time and across situations, as well as sociodemographic variation herein. METHODS: We employed data from five rounds of a cohort study conducted throughout the pandemic by the Dutch public health institute (RIVM; N ≈ 50.000 per round). We conducted Latent Class Analyses to investigate patterns of physical distancing in a range of situations, followed by regression models to investigate associations between distancing behavior and sociodemographic and context characteristics. RESULTS: Participants differed in their general tendency to adhere to distancing guidelines across situations, but there were also substantial differences in distancing behavior between situations, particularly at work, with friends and family and outdoors. Distancing at work was strongly associated with work environment characteristics. Younger age groups reported less distancing behavior, particularly with close relations (friends or family) and at work. In periods when the pandemic situation was most severe, people adhered more strongly to distancing guidelines and age differences were most pronounced during these periods. CONCLUSIONS: Physical and social context matters for physical distancing, highlighting the importance of developing strategies for pandemic preparedness that improve opportunities for physical distancing (e.g., reducing crowding, one-way traffic) and accommodate young people to safely meet even in times of high pandemic severity and lockdowns. Future studies should account for the physical and social context in which distancing behavior is observed.

Physical distancing helps reduce the transmission of infectious diseases, but people's opportunities and willingness to keep distance from others can vary between situations. In a survey conducted at various time points during the Covid-19 pandemic, The Dutch National Public Health Institute asked people about their distancing behavior in various such situations, such as at work, when grocery shopping or when visiting with friends and family. We found that people mainly differed in their general tendency to keep distance from others: some individuals were more likely to keep distance than others in all situations. However, there were also substantial differences in distancing behavior at work, with friends and family and outdoors. Differences in distancing at work resulted from the specific work context and activities people had to perform. Younger age groups reported less distancing behavior in social situations such as when meeting with friends and family or with colleagues. In periods when the pandemic situation was most severe, people were more likely to keep their distance from others and there were larger age differences in distancing behavior. These results highlight the importance of improving people's opportunities to keep their distance from others and safely meet in times of a severe pandemic.

Bans on tobacco display, advertising and vending machines in the Netherlands: impact on visibility of tobacco and compliance of retailers.

INTRODUCTION: Visibility of tobacco products at retail tobacco outlets is associated with smoking initiation. To address this, across 2020-2022 the Netherlands banned tobacco product displays, advertisements and vending machines in the retail environment. Tobacco/vape specialist shops were exempted. This study assessed the impact of these policies on tobacco visibility in the retail environment and retailer compliance. METHODS: We conducted observational audits of all tobacco outlets in four Dutch cities (Amsterdam, Haarlem, Eindhoven and Zwolle) between 2019 and 2022 (before and after policy implementation), assessing visibility of tobacco products and advertisements, compliance and remaining sources of tobacco visibility (after implementation). We described results by location and outlet type. RESULTS: The number of tobacco outlets with any tobacco advertising or product visibility declined from 530 to 267 (-50%). Among outlets not exempt from the ban, the number with visibility declined from 449 to 172 (-62%), with lower postban visibility in petrol stations (12%) and supermarkets (6%) than small shops (47%). Visibility among tobacco/vape shops increased by 17%. Tobacco product displays remained the main source of visibility. 93% of tobacco vending machines were removed. Maps showed that non-compliance is concentrated in Amsterdam's city centre and more evenly distributed in other cities. CONCLUSION: The bans on tobacco display and tobacco advertising halved the visibility of tobacco in the retail environment, and the vending machine ban practically eradicated vending machines. To further reduce tobacco visibility, violations in small shops should be addressed and tobacco visibility should be regulated in currently exempt tobacco specialist shops.

Socioeconomic differences in tobacco outlet presence, density, and proximity in four cities in the Netherlands.

BACKGROUND: Previous studies found that tobacco outlets were unevenly distributed by area socioeconomic status (SES). However, evidence from continental Europe is limited. This study aims to assess differences in tobacco outlet presence, density and proximity by area SES in the Netherlands. METHODS: All tobacco outlets in four Dutch cities (Amsterdam, and medium-sized cities Eindhoven, Haarlem, and Zwolle) were mapped between September 2019 and June 2020. We estimated associations between average property value of neighbourhoods (as an indicator of SES, grouped into quintiles) and (1) tobacco outlet presence in the neighbourhood (yes/no), (2) density (per km2), and (3) proximity to the closest outlet (in meters), using logistic and linear regression models. RESULTS: 46% of neighbourhoods contained at least one tobacco outlet. Tobacco outlets were mostly situated in city centres, but the distribution of tobacco outlets varied per city due to differences in urban structures and functions. In the medium-sized cities, each quintile higher neighbourhood-SES was associated with lower tobacco outlet presence (OR:0.71, 95%CI:0.59;0.85), lower density (B:-1.20 outlets/km2, 95%CI:-2.20;-0.20) and less proximity (B:40.2 m, 95%CI 36.58;43.83). Associations were the other way around for Amsterdam (OR:1.22, 95%CI:1.05;1.40, B:3.50, 95%CI:0.81;6.20, and B:-18.45, 95%CI:-20.41;-16.49, respectively). Results were similar for most types of tobacco outlets. CONCLUSION: In medium-sized cities in the Netherlands, tobacco outlets were more often located in low-SES neighbourhoods than high-SES. Amsterdam presented a reverse pattern, possibly due to its unique urban structure. We discuss how licensing might contribute to reducing tobacco outlets in low-SES neighbourhoods.

Dealing with Alcohol-Related Posts on Social Media: Using a Mixed-Method Approach to Understand Young Peoples' Problem Awareness and Evaluations of Intervention Ideas.

Young individuals frequently share and encounter alcohol-related content (i.e., alcohol posts) on social networking sites. The prevalence of these posts is problematic because both the sharing of and exposure to these posts can increase young individuals' alcohol (mis)use. Consequently, it is essential to develop effective intervention strategies that hinder young individuals from sharing these posts. This study aimed to develop such intervention strategies by following four steps: (1) assessing young individuals' problem awareness of alcohol posts, (2) unraveling individuals' own intervention ideas to tackle the problem of alcohol posts, (3) examining their evaluations of theory/empirical-based intervention ideas, and (4) exploring individual differences in both problem awareness and intervention evaluations. To reach these aims, a mixed-method study (i.e., focus-group interviews and surveys) among Dutch high-school and college students (Ntotal = 292, Agerange = 16-28 years) was conducted. According to the results, most youth did not consider alcohol posts to be a problem and were, therefore, in favor of using automated warning messages to raise awareness. However, these messages might not work for every individual, as group differences in problem awareness and intervention evaluations exist. Overall, this study puts forward potential intervention ideas to reduce alcohol posts in digital spheres and can therefore serve as a steppingstone to test the actual effects of the ideas.

Smokers' strategies to reduce tobacco spending: self-reported use and differences across subgroups. Findings from the International Tobacco Control (ITC) Netherlands Survey.

BACKGROUND: The cost of tobacco is one of the most reported reasons for smoking cessation. Rather than quitting, smokers can use also strategies to reduce tobacco expenditure while continuing smoking, such as smoking less or using price-minimising strategies. The Netherlands announced to increase the price of a pack cigarettes from seven (2018) to ten euros (2023), to reduce tobacco prevalence and consumption. This study explores the self-reported strategies to reduce tobacco spending among Dutch smokers, and whether this differed per age, income, and education. Additionally, we analysed among quitters in these subgroups whether price played a role in their decision to quit. METHODS: Cross-sectional survey data from the International Tobacco Control (ITC) Netherlands Wave 2 (September-November 2020, N = 1915) was used. Strategies to reduce spending among smokers (N = 1790) were: reducing consumption, bulk buying, switching to cheaper products or buying from low-taxed sources. These were collapsed into: reducing consumption (solely or in combination with other behaviours), solely price-minimising behaviours (such as buying cheaper brands), or no strategies to reduce spending. Associations between strategies and characteristics were analysed through multinomial and binary logistic regression models. Second, we explored which subgroups were more likely to report that price played a role in their decision to quit among quitters (N = 125). RESULTS: The majority of smokers used strategies to reduce tobacco spending: 35.6% reduced consumption and 19.3% used solely price-minimising strategies. 82.1% of quitters reported that price played a role in their decision to quit. Low-income individuals were more likely to report price as a reason for quitting and reduce consumption, but also to buy cheaper products. Highly nicotine dependent smokers were more likely to use price-minimising behaviours, and less likely to reduce consumption. CONCLUSIONS: The majority reported using strategies to reduce spending or that price played a role in their decision to quit. Reducing consumption was the most reported strategy. Low-income smokers were more likely to reportedly reduce consumption, buy cheaper products, or quit. Price policies have the potential to reduce socioeconomic inequalities in smoking. To discourage price-minimising behaviours, such as switching to cheaper products, reducing price differences between products should be prioritized.

Understanding public support for COVID-19 pandemic mitigation measures over time: Does it wear out?

Background: COVID-19 mitigation measures intend to protect public health, but their adverse psychological, social, and economic effects weaken public support. Less favorable trade-offs may especially weaken support for more restrictive measures. Support for mitigation measures may also differ between population subgroups who experience different benefits and costs, and decrease over time, a phenomenon termed "pandemic fatigue." Methods: We examined self-reported support for COVID-19 mitigation measures in the Netherlands over 12 consecutives waves of data collection between April 2020 and May 2021 in an open population cohort study. Participants were recruited through community panels of the 25 regional public health services, and through links to the online surveys advertised on social media. The 54,010 unique participants in the cohort study on average participated in 4 waves of data collection. Most participants were female (65%), middle-aged [57% (40-69 years)], highly educated (57%), not living alone (84%), residing in an urban area (60%), and born in the Netherlands (95%). Results: COVID-19 mitigation measures implemented in the Netherlands remained generally well-supported over time [all scores >3 on 5-point scale ranging 1 (low)-5 (high)]. During the whole period studied, support was highest for personal hygiene measures, quarantine and wearing face masks, high but somewhat lower for not shaking hands, testing and self-isolation, and restricting social contacts, and lowest for limiting visitors at home, and not traveling abroad. Women and higher educated people were more supportive of some mitigation measures than men and lower educated people. Older people were more supportive of more restrictive measures than younger people, and support for more socially restrictive measures decreased most over time in higher educated people or in younger people. Conclusions: This study found no support for pandemic fatigue in terms of a gradual decline in support for all mitigation measures in the first year of the pandemic. Rather, findings suggest that support for mitigation measures reflects a balancing of benefits and cost, which may change over time, and differ between measures and population subgroups.

My future-self has (not) quit smoking: An experimental study into the effect of a future-self intervention on smoking-related self-identity constructs.

OBJECTIVES: Envisioning one's (non)smoking future may make (un)desired future identities more accessible, salient, and personally relevant and facilitate smoking cessation. The current study assessed whether a future-self intervention can weaken smoker self-identity and expected identity loss when quitting smoking, and strengthen quitter- and nonsmoker self-identity, while accounting for personal factors-socioeconomic position, nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Additionally, it examined the association between smoking-related identity and quitting intention and behavior. METHODS: This longitudinal online experimental study randomized 233 adult smokers to an intervention condition (where they completed mental imagery, visual, and verbal tasks about a future (non)smoking self), or to a passive control condition. Smoker-, quitter-, nonsmoker self-identity and identity loss were measured post-intervention and after one- and three-months. Quit intention and attempts were measured at baseline and after one month. RESULTS: There was a consistent increase in non-smoker self-identity, and decrease in smoker self-identity and identity loss over a period of six months for all participants, but no significant difference in smoking-related identity between the intervention and control group. While personal factors did not moderate the effect of the intervention, we found that smoking-related identity constructs do vary with nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Quitting behavior is primarily associated with non-smoker self-identity. CONCLUSIONS: Although the future-self intervention did not significantly influence smoking-related identity or behavior, identity-in particular, non-smoker self-identity-is important to consider in smoking cessation interventions. More research is needed to find effective operationalizations for identity-based interventions in the context of smoking.

Smoking Cessation Among Gender Minority Populations, Cis-women, and Cis-men: Findings From the International Tobacco Control Netherlands Survey.

INTRODUCTION: Little is known about smoking cessation among gender minority populations compared to cisgender individuals (whose gender matches their sex assigned at birth). We examined differences between smokers from gender minority populations, cis-women, and cis-men in the heaviness of smoking, quit intentions, use of cessation assistance, quit attempts (ever tried and number), and triggers for thinking about quitting. AIMS AND METHODS: We used cross-sectional data from the 2020 International Tobacco Control Netherlands Survey. Among smoking respondents, we distinguished (1) cis-women (female sex, identified as women, and having feminine gender roles; n = 670), (2) cis-men (male sex, identified as men, and having masculine gender roles; n = 897), and (3) gender minorities (individuals who were intersex, who identified as nonbinary, genderqueer, had a sex/gender identity not listed, whose gender roles were not feminine or masculine, or whose gender identity and/or roles were not congruent with sex assigned at birth; n = 220). RESULTS: Although gender minorities did not differ from cis-women and cis-men in the heaviness of smoking, plans to quit smoking, and quit attempts, they were significantly more likely to use cessation assistance (20% in the past 6 months) than cis-women (12%) and cis-men (9%). Gender minorities were also significantly more likely to report several triggers for thinking about quitting smoking, for example, quit advice from a doctor, an anti-smoking message/campaign, and the availability of a telephone helpline. CONCLUSION: Despite equal levels of quit attempts and heaviness of smoking, gender minority smokers make more use of smoking assistance, and respond stronger to triggers for thinking about quitting smoking. IMPLICATIONS: Smoking cessation counselors should be sensitive to the stressors that individuals from any minority population face, such as stigmatization, discrimination, and loneliness, and should educate their smoking clients on effective coping mechanisms to prevent relapse into smoking after they experience these stressors. Developing tailored smoking cessation programs or campaigns specifically for gender minority populations can also be useful. Based on the results of our subgroup analyses, programs or campaigns for younger gender minority smokers could focus on the availability of telephone helplines and on how friends and family think about their smoking behavior.

Trends in Individualized Affordability of Factory-Made Cigarettes: Findings of the 2008-2020 International Tobacco Control Netherlands Surveys.

INTRODUCTION: Cigarette affordability, the price of tobacco relative to consumer income, is a key determinant of tobacco consumption. AIMS AND METHODS: This study examined trends over 12 years in individualized factory-made cigarette affordability in the Netherlands, and whether these trends differed by sex, age, and education. Data from 10 waves (2008-2020) of the International Tobacco Control Netherlands Surveys were used to estimate individualized affordability, measured as the percentage of income required to buy 100 cigarette packs (Relative Income Price [RIP]), using self-reported prices and income. The higher the RIP, the less affordable cigarettes are. Generalized estimating equation regression models assessed trends in individualized affordability over time and by sex, age, and education. RESULTS: Affordability decreased significantly between 2008 and 2020, with RIP increasing from 1.89% (2008) to 2.64% (2020) (p ≤ .001), except for 2008-2010, no significant year-on-year changes in affordability were found. Lower affordability was found among subgroups who have a lower income level: Females (vs. males), 18-24 and 25-39-year-olds (vs. 55 years and over) and low or moderate-educated individuals (vs. highly educated). Interactions between wave and education (p = .007) were found, but not with sex (p = .653) or age (p = .295). A decreasing linear trend in affordability was found for moderately (p = .041) and high-educated (p = .025), but not for low-educated individuals (p = .149). CONCLUSIONS: Cigarettes in the Netherlands have become less affordable between 2008 and 2020, yet this was mostly because of the decrease in affordability between 2008 and 2010. There is a need for more significant increases in tax to further decrease affordability. IMPLICATIONS: Our findings suggest that cigarettes have become less affordable in the Netherlands between 2008 and 2020. But, this appears to be the result of a steep decrease in affordability between 2008 and 2010. Affordability was lower among groups who have on average lower incomes (females, young adults, and low- and moderate-educated individuals), and differences in trends across education levels could be explained by per capita income changes. Our individualized measure indicated lower affordability than published aggregate affordability estimations. Future tax increases should be large enough to result in a lower affordability.

The association between objectively measured exposure to tobacco outlets and smoking cognitions: a study among non-smoking adolescents in four Dutch cities.

AIMS: Exposure to tobacco products and advertising at the point of sale may be associated with pro-smoking cognitions. However, previous studies on this topic measured exposure based on self-report and did not include European countries. The aim of this study was to assess the association between objectively measured exposure to tobacco outlets and non-smoking adolescents' smoking attitudes, beliefs and norms. DESIGN: This cross-sectional study combined survey data with Global Positioning Systems data using geographic information system. SETTING: The four Dutch cities of Amsterdam, Eindhoven, Haarlem and Zwolle. PARTICIPANTS: We retrieved data of 308 13 to 17-year-old non-smoking adolescents, mainly girls (61%), adolescents attending pre-university secondary education (71%) and without smoking friends (58%). MEASUREMENTS: Exposure was measured with a smartphone app registering for 2 weeks how often participants were within 10 m of a tobacco outlet. We distinguished between outlets without visible tobacco promotion (i.e. supermarkets), with only internal visibility and with both internal and external visibility. Participants' reported smoking cognitions were dichotomised into pro-smoking or anti-smoking. We applied multi-level logistic regression analyses and adjusted for age, sex, educational level and smoking friends. FINDINGS: On average, adolescents were exposed to 1.18 (SD = 1.23) tobacco outlets per day. Higher exposure to tobacco outlets was associated with higher odds of pro-smoking injunctive norm ( OR = 1.35, 95% CI = 1.04-1.75). Associations with attitude (OR = 1.12, 95% CI = 0.91-1.38), social beliefs (OR = 1.15, 95% CI = 0.93-1.43), health beliefs (OR = 1.18, 95% CI = 0.97-1.44) and descriptive norm (OR = 1.15, 95% CI = 0.91-1.44) were also positive, but non-significant. Overall, associations were strongest for outlets with internal visibility, for instance, for injunctive norm (OR = 1.37, 95% CI = 1.03-1.81). CONCLUSIONS: Global Positioning Systems-measured exposure to tobacco outlets was associated with pro-smoking cognitions among non-smoking adolescents in the Netherlands.

Ex ante evaluation of the impact of tobacco control policy measures aimed at the point of sale in the Netherlands.

INTRODUCTION: The Netherlands aims to implement stricter tobacco control policies targeting the retail environment. This paper is an ex ante policy evaluation of the potential impact of the current tobacco display and advertising ban as well as future tobacco sales bans on tobacco outlet visibility and availability. METHODS: Between September 2019 and June 2020, all potential tobacco retailers in four Dutch cities (Amsterdam, Eindhoven, Haarlem and Zwolle) were visited and mapped using Global Positioning System. For each retailer selling tobacco, we completed a checklist on the visibility of tobacco products and advertising. Expected reductions in tobacco outlet visibility and availability were calculated per policy measure in absolute numbers (percentage or percentage point decrease) as well as density and proximity. RESULTS: Out of 870 tobacco outlets, 690 were identified with visible tobacco products/advertising. The display ban in supermarkets and small outlets (respectively) is expected to decrease the number (-15; -42 percentage points), outlet density per 10 000 capita (-0.9; -2.6) and proximity in metres (+27 m; +400 m) of outlets with visible products/advertising. The upcoming bans on vending machines and sales in supermarkets are expected to decrease the number (-12%; -31%), density (-0.7; -1.9) and proximity (+12 m; +68 m) of tobacco outlets. Further changes in the number, density and proximity (respectively) of tobacco outlets may be achieved with future sales bans in petrol stations (-7%; -0.4; +60 m) and particularly with a ban on sales in small outlets (-43%; -2.7; +970 m). CONCLUSION: A display ban and a sales ban in small outlets will contribute most to reducing tobacco outlet visibility and availability, assuming that no market shift towards other tobacco outlets will take place.

Physical Distancing and Social Media Use in Emerging Adults and Adults During the COVID-19 Pandemic: Large-scale Cross-sectional and Longitudinal Survey Study.

Background: Although emerging adults play a role in the spread of COVID-19, they are less likely to develop severe symptoms after infection. Emerging adults' relatively high use of social media as a source of information raises concerns regarding COVID-19-related behavioral compliance (ie, physical distancing) in this age group. Objective: This study aimed to investigate physical distancing among emerging adults in comparison with adults and examine the role of using social media for COVID-19 news and information in this regard. In addition, this study explored the relationship between physical distancing and using different social media platforms and sources. Methods: The secondary data of a large-scale longitudinal national survey (N=123,848) between April and November 2020 were used. Participants indicated, ranging from 1 to 8 waves, how often they were successful in keeping a 1.5-m distance on a 7-point Likert scale. Participants aged between 18 and 24 years were considered emerging adults, and those aged >24 years were considered adults. In addition, a dummy variable was created to indicate per wave whether participants used social media for COVID-19 news and information. A subset of participants received follow-up questions to determine which platforms they used and what sources of news and information they had seen on social media. All preregistered hypotheses were tested with linear mixed-effects models and random intercept cross-lagged panel models. Results: Emerging adults reported fewer physical distancing behaviors than adults (ß=-.08, t86,213.83=-26.79; P<.001). Moreover, emerging adults were more likely to use social media for COVID-19 news and information (b=2.48; odds ratio 11.93 [95% CI=9.72-14.65]; SE 0.11; Wald=23.66; P<.001), which mediated the association with physical distancing but only to a small extent (indirect effect: b=-0.03, 95% CI -0.04 to -0.02). Contrary to our hypothesis, the longitudinal random intercept cross-lagged panel model showed no evidence that physical distancing was not influenced by social media use in the previous wave. However, evidence indicated that social media use affects subsequent physical distancing behavior. Moreover, additional analyses showed that the use of most social media platforms (ie, YouTube, Facebook, and Instagram) and interpersonal communication were negatively associated with physical distancing, whereas other platforms (ie, LinkedIn and Twitter) and government messages had no or small positive associations with physical distancing. Conclusions: In conclusion, we should be vigilant with regard to the physical distancing of emerging adults, but the study results did not indicate concerns regarding the role of social media for COVID-19 news and information. However, as the use of some social media platforms and sources showed negative associations with physical distancing, future studies should more carefully examine these factors to better understand the associations between social media use for news and information and behavioral interventions in times of crisis.

Educational inequalities in exposure to tobacco promotion at the point of sale among adolescents in four Dutch cities.

This study aimed to assess educational differences in adolescents' exposure to tobacco outlets. Data were collected among 312 13-17-year-old non-smoking secondary school students in four Dutch cities. In a smartphone app, exposure (≤10 m from outlet) was measured using GPS and participants reported their educational track (pre-vocational vs. pre-university). Associations were estimated in negative binomial regression models. Mean exposure to tobacco outlet was 16.6 times in 14 days. Pre-vocational education was associated with higher exposure compared to pre-university education (IRR:1.46, 95%CI:1.08-1.98), especially around school (IRR:2.61,95%CI:1.50-4.55). These differences may contribute to socioeconomic inequalities in smoking.

Non-smoking adolescents' perceptions of dissuasive cigarettes.

Introduction: Dissuasive cigarettes, cigarettes with an unappealing colour or displaying a health warning label, may deter young people from smoking uptake. Methods: Two online surveys were conducted with non-smokers aged 12-17 to explore perceptions of cigarette appeal, harm and product trial. Study 1 was a within-subject study which examined perceptions of four cigarettes with different coloured paper, and four cigarettes displaying a warning. Study 2 was a between-subject study (with limited power), in which respondents were randomized to one of four cigarettes: (1) regular cigarette; (2) least favourable warning from Study 1; (3) least favourable colour from Study 1; or (4) a combination of the least favourable warning and colour from Study 1. Warnings or colours were considered least favourable when they had lower scores on appeal, harm, and product trial. Results: In Study 1, a cigarette featuring the warning 'cancer, heart disease, stroke' and a drab dark brown cigarette were rated lowest on appeal and trial intentions, and highest on perceived harm. In Study 2, there were no significant differences in perceptions of appeal, harm or trial intentions between the regular and dissuasive cigarettes. Conclusions: Findings from our within-subject study suggest that a cigarette displaying the text 'cancer, heart disease, stroke' and a drab dark brown coloured cigarette are most dissuasive for Dutch non-smoking adolescents. Whether dissuasive cigarettes reduce appeal, reduce product trial, or increase perceptions of harm compared to a regular cigarette should be further examined in larger between-subject studies.

Demand for Factory-Made Cigarettes and Roll-Your-Own Tobacco and Differences Between Age and Socioeconomic Groups: Findings From the International Tobacco Control Netherlands Survey.

INTRODUCTION: Macroeconomic studies have shown that young individuals who smoke, and have a low socioeconomic status respond more strongly to price increases. Most of this evidence stems from research on factory-made (FM) cigarettes. With the rising popularity of roll-your-own (RYO) tobacco, there is a need for studies on cigarette demand that distinguish between both. AIMS AND METHODS: This study examined whether individual demand differed for FM and RYO tobacco, and across age, and socioeconomic (income and education) groups. Purchase tasks for FM and RYO cigarettes were included in the 2020 International Tobacco Control (ITC) Netherlands Survey. Adults who smoke daily (n = 1620) stated how many cigarettes they would smoke in 24 hours across eight prices. Four demand indices were derived: intensity (consumption at zero costs), alpha (rate of change in elasticity), Pmax (turning point elasticity), and breakpoint (lowest price where consumption equals zero). The indices were tested for subgroup differences. RESULTS: Individuals who smoke RYO tobacco indicated higher intensity, and greater alpha than individuals who smoke FM cigarettes. Participants aged 25-39 had lower Pmax, and 18-24 year olds displayed higher breakpoints. Participants with low income displayed higher intensity, and lower Pmax than other income groups. No associations were found with education. CONCLUSIONS: Individuals who smoke RYO tobacco indicated higher price sensitivity than those smoking FM cigarettes, supporting the need to harmonize tobacco taxation. Taxation may be especially beneficial to reducing consumption among individuals with a low income or smoke RYO tobacco. Substantially higher prices are needed in the Netherlands to achieve the desired results. IMPLICATIONS: Individuals who smoke daily were willing to pay substantially higher prices than the current market prices, indicating the room and need for much higher taxation levels. Demand for RYO tobacco was more sensitive to price changes than demand for FM cigarettes. Taxation should be raised at equivalent rates for FM and RYO cigarettes. Taxation appears to be especially effective in reducing consumption among people who smoke RYO tobacco and low-income individuals. It remains important to combine increased taxation with other tobacco control measures.

The Antecedents and Consequences of Interpersonal Communication during a School-based Health Intervention.

School-based health interventions often have limited and inconsistent effects. Although interpersonal communication likely is important, hardly any studies have investigated interpersonal communication of students with their friends, classmates, and parents about the health programs and health behaviors in school-based health interventions. In a two-wave prospective study of 389 adolescents focusing on three health behaviors (i.e., alcohol use, snack intake, and exercise), we addressed two aims. Our first aim was to investigate how student evaluations of a school-based health intervention influenced interpersonal communication about health behaviors (i.e., valence and frequency of conversations). Findings showed that positively evaluating a school-based health intervention increased how often students talked about the intervention with friends, classmates, and parents, as well as how they discussed the three health behaviors. Our second aim was to investigate the influence of interpersonal communication with friends, classmates, and parents on predictors of health behaviors. We found for conversational frequency that frequently discussing health behaviors resulted in healthier (more positive) predictors of exercise, but also in unhealthier (more positive) predictors of snacking and drinking. Furthermore, findings showed that positively discussing exercising, and negatively discussing snacking and drinking, resulted in healthier predictors of these behaviors. Our findings show that it is important to understand the impact of post-intervention communication and that post-intervention communication with peers and parents about health behaviors are predictors of health behavior.

The Intervening Role of Conversational Frequency and Valence in a School-Based Health Intervention.

School-based health interventions are potentially an effective method to communicate health messages to adolescents. Unfortunately, effectiveness of such interventions is limited. Research in other contexts has shown that interpersonal communication can influence the effectiveness of health programs, but this has not been thoroughly tested for school-based health interventions. Therefore, our study investigated interpersonal communication (i.e., conversational valence and frequency) in a school-based intervention context. We used a three-wave randomized-controlled trial with 1056 students to study three aims. The first aim was to investigate the influence of a health intervention on conversational frequency and valence about drinking, snacking, and exercising. Our second aim was to investigate the influence of conversational frequency and valence on (predictors of) drinking, snacking, and exercising. Our third aim was to investigate whether the health intervention indirectly influenced the program outcomes through conversational frequency and valence. Findings showed that conversational frequency and valence were related to (predictors of) the three behaviors. Additionally, findings showed that the intervention did not influence conversational frequency and valence. Accordingly, findings showed no indirect influence of the intervention on program outcomes through conversational frequency and valence. Our findings show the potential of interpersonal communication for health behaviors and predictors; however, they also stress the importance of a health intervention to properly influence interpersonal communication. If health interventions can successfully influence interpersonal communication, intervention effectiveness can be improved.

Tobacco Retailers' Support for Point-of-Sale Tobacco Control Policies in England: Association Study of Retailers' Perceived Importance of Tobacco Sales, Contact with the Tobacco Industry, and the Perceived Impact of the Policy.

INTRODUCTION: Political acceptability and successful implementation of tobacco control policies at the point of sale may depend on, among other factors, tobacco retailers' level of support for these policies. This study quantified the level of support among small tobacco retailers for four point-of-sale tobacco control policies and its association with three predictors. METHODS: We used cross-sectional telephone survey data (August 2019) of 508 small tobacco retailers in England. Weighted logistic regression analyses examined associations between support for the product display ban, price display ban, minimum pack size, and standardized packaging, and self-reported importance of tobacco sales for a business, contact with the tobacco industry, and the perceived impact of the policy on their overall business. RESULTS: A majority of retailers support minimum pack size (66%), product display ban (65%), price display ban (54%), and standardized packaging (55%). The importance of tobacco sales was not associated with support for the policies. More frequent contact with the tobacco industry was associated with higher odds of support for minimum pack size (OR: 2.01, 95%CI:1.25-3.21), but not with the other three policies. The negative perceived impact of the policies, compared with neutral, was associated with 1.5 to three times lower odds of support for all four policies. CONCLUSION: In England, small retailers' support for the four point-of-sale tobacco control policies varied between 54% and 66%. Support seems unrelated to the perceived importance of tobacco sales, and contact with the tobacco industry, but seems strongly related to the perceived impact of tobacco control policies on their business. IMPLICATIONS: This study shows that small independent retailers' support for point-of-sale (PoS) tobacco control policies is fairly high and that the lack of support voiced by retail trade organizations is not representative of the views of retailers in England. Support rates may be further improved by addressing retailers' perceptions of the impact of policies on their business. Support was not related to retailers' perceived importance of tobacco sales for their business and their contact with the tobacco industry. The industry rhetoric is not supported by our findings, as the majority of small independent retailers in England support tobacco control regulations.

Causal Effects of Alcohol-Related Facebook Posts on Drinking Behavior: Longitudinal Experimental Study.

BACKGROUND: Adolescents and young adults frequently post alcohol-related content (ie, alcoholposts) on social media. This is problematic because both social norms theory and social learning theory suggest that viewing alcoholposts of peers could increase drinking behavior. It is therefore paramount to understand the effects of exposure to alcoholposts on viewers. OBJECTIVE: This study aimed to investigate the causal effects of exposure to alcoholposts on alcohol consumption by using a rigorous design. METHODS: We conducted a 6-week longitudinal study during which alcoholposts were measured by a newly developed app that copied Facebook posts shared by participants (n=281) to a new social media environment. In addition, daily questionnaires assessed alcohol use. Effects of natural alcoholposts (ie, posted by the participants) were assessed in phase 1, and effects of experimental posts (ie, posted by fake participants) were explored in phase 2. RESULTS: Results showed that natural alcoholposts increased the occurrence and quantity of drinking the following day. That is, exposure to a single additional alcoholpost increased the log odds of drinking the next day by 0.27 (b=.27, credible interval [CI] .18 to .35). Furthermore, the number of natural alcoholposts had a positive (predictive) effect on the number of glasses drunk the next day (b=.21, CI .14 to .29). In phase 2 when experimental posts were also present, these effects decreased. Experimental posts themselves had hardly any effects. CONCLUSIONS: This study illustrates clear and direct effects of exposure to alcoholposts on next-day alcohol consumption and suggests that alcoholposts represent an important societal problem that interventions need to address.

Dutch youth's smoking behaviour during a partial Covid-19 lockdown.

Previous research found that adult smokers increased their smoking in response to the Covid-19 lockdown in spring 2020. This study explored changes in youth's smoking during, compared to before, the partial lockdown in the Netherlands in a cross-sectional sample of 287 adolescents. Smoking prevalence increased from 4.5% to 5.2%. Cigarette consumption remained the same on school days and increased with +1.9 cigarettes per weekend day. The largest increase in cigarette consumption on weekend days was observed for adolescents who 1) did not consider smoking a risk factor for contracting Covid-19 (+4.5), 2) had smoking siblings (+4.1), and 3) had smoking friends (+2.4). Youth without smoking friends (-0.8) and who considered smoking a risk factor for Covid-19 (-0.2) decreased their cigarette consumption.
