Revised Amendments from Version 1
The Title was changed to ‘Protocol for a feasibility study of longitudinal surveys to assess the impact of policies on tobacco use among school-going adolescents in South Asia’.
Objective 3 was rephrased as ‘To evaluate if the questionnaire can assess tobacco uptake and use, and their potential predictors’.
The term ‘Secondary school students’ was changed to ‘school going adolescents’.
We updated the reference of GYTS India 2009 to GYTS India 2019.
We added ‘Evidence showed that most smokers start smoking in adolescence (NCBI 2012) and between one-third and one-half of adolescents who experiment with smoking become regular smokers (ASH 2018). The prevalence of ST use in the adult population is high in these countries that pose serious disease burden (Siddiqi 2020)’ in the Introduction section.
We added the rationale ‘Assessing both smoking and ST will give us the opportunity to compare the policy impact for both forms of tobacco use’ to the Introduction section.
In the Methods section, we added more information as suggested by the peer reviewers.
We changed Figure 1 to be in the past tense.
As suggested, we added details in the ‘Consent’ that ‘It was mentioned in consent and assent form that participants were free to withdraw any time as per their wish without showing any reason. In that case, no more data would be collected. The information already collected will be kept secure and still used in the analysis unless the participant specifically asks for the information to be removed.’
We added some text in ‘Confidentiality’ that ‘The data collection was monitored by the investigators to ensure that no participant can view another participant’s responses in the questionnaire to maintain confidentiality.’
We also added some text in ‘Risk, burdens and benefits’ and ‘Data protection’ sections.
We added three new citations.

Introduction
Use of different types of tobacco products, both smoking and smokeless tobacco (ST), is a complex public health challenge for many countries (United States National Cancer Institute, 2016). ST use poses complex problems, because its characteristics, patterns of use, health effects, production practices, and policy responses vary widely between countries and regions. In total, 85% of the world’s 300 million ST users live in South Asia and use the most lethal ST forms, which contain high levels of carcinogens, notably tobacco-specific nitrosamines (Stanfill et al., 2011). The use of these forms of ST leads to head and neck cancers and increases the risk of cardiovascular deaths (Sinha et al., 2016; Vidyasagaran et al., 2016). Over 650,000 deaths per year, due to all causes, could be attributed to ST use worldwide; with 88% of this burden borne in South-Asia alone (Sinha et al., 2018). Despite the huge burden on health and the economy, ST remains largely neglected by policy makers and researchers, particularly in low and middle-income countries (LMICs). ST control has received less attention than smoking control and ST policies are poorly developed and have not been supported by high-quality research (Siddiqi et al., 2017). Compared to smoking, there is a huge policy implementation gap for ST (Mehrotra et al., 2019). The evidence for Framework Convention on Tobacco Control (FCTC) measures is mostly derived from cigarettes and the experiences in high-income countries. Little is known about their transferability to ST use in LMICs. Furthermore, most South Asian institutions do not have enough researchers or funds to carry out high-quality research in this area. Bangladesh, India, and Pakistan are three LMICs in South Asia where smoking and ST use have become an increasingly prevalent problem (Islam et al., 2014). Despite being signatories of the World Health Organisation (WHO) FCTC, these countries have made little progress towards tobacco control policies, in particular for ST (Mamudu et al., 2016; U.S. National Cancer Institute, 2016). For youth, the issue is even more complex as policies that work for the adult population might not be effective (Crawford et al., 2002). There is a need to develop a wider evidence-based response to FCTC for ST, particularly for youth in these countries.
A study assessing tobacco use among adolescents aged 12–15 years in 68 LMICs showed that mean prevalence of current tobacco use was 13.6%. About 10% of adolescents were cigarette smokers, while 8.1% were users of non-cigarette products that included ST (Xi et al., 2016). According to the recent Global Youth Tobacco Survey (GYTS), 4.5%, 4.1% and 5.3% of students were current ST users in Bangladesh (GYTS Bangladesh, 2013), India (GYTS India, 2019) and in Pakistan (GYTS Pakistan, 2013), respectively. Evidence showed that most smokers start smoking in adolescence (NCBI, 2012) and between one-third and one-half of adolescents who experiment with smoking become regular smokers (ASH, 2018). The prevalence of ST use in adult population is high in these countries that poses serious disease burden (Siddiqi et al., 2020). Since most adult tobacco users start ST use in adolescence, young people are targeted by the tobacco industry (Wen et al., 2005) and ST manufacturers (Connolly, 1995; Tobacco Free Initiative & WHO, 2002). Thus, it is important to address tobacco use and prevent the initiation of ST in adolescents, which would protect against the health risks of ST use in adult life. The WHO FCTC provides specific legislative measures to inhibit tobacco access and use by youth, increase awareness of the harm caused by tobacco and prevent the promotion of tobacco through sponsorship and advertisements (WHO, 2003). Nonetheless, little is known about the impact of such tobacco policies on tobacco uptake and use among youth, due to lack of testing of effectiveness of policies in these countries. Within the current surveillance system, due to the cross-sectional design of the GYTS survey, it was only possible to look at the prevalence and associations but not a true evaluation of impact of the tobacco control policy. Moreover, questionnaires used in the GYTS ask specific questions for smoking but do not include similar questions on ST (sale, ST exposure outside the home and/or public places, health warnings on ST pack). Therefore, there is a gap of comprehensive assessment of ST.
We plan to conduct longitudinal surveys among secondary school students (class 6, 7 and 8 students), to test the impact of existing tobacco control policies. We will focus specifically on price and taxation policies, packaging and labelling policies for both smoking and ST products, raising public awareness of tobacco-related harms, banning tobacco advertisement, promotion and sponsorship of tobacco, and policies banning tobacco sales to minors. The main aim of the study will be to test awareness of and exposure to policies and to assess their impact on ST use among adolescents over time compared to smoking. Assessing both smoking and ST will give us the opportunity to compare the policy impact for both form of tobacco use. We have developed a comprehensive questionnaire that will cover both cigarette and ST use, and awareness and exposure to various tobacco control policies.
Feasibility studies are carried out before the main studies in order to test the processes involved (such as recruitment and retention of study participants and procedures for data collection) and estimate important parameters that are needed to design the main study (Arain et al., 2010). Most longitudinal studies have been carried out on smoking and very few of those included ST use. As very limited longitudinal studies have been conducted on high school students in Bangladesh, India and Pakistan to evaluate tobacco control policies particularly focusing on ST uptake, therefore, it is important to conduct a feasibility study before the envisaged longitudinal study.
Study aim and objectives
Aim
To assess the feasibility of conducting longitudinal surveys among secondary school students in Bangladesh, India and Pakistan to evaluate existing tobacco control policies on ST uptake and use among this group.
Objectives
1. To demonstrate the feasibility of selection, recruitment and retention of schools and of study participants.
2. To assess the feasibility and acceptability of the study procedure and study tool (questionnaire).
3. To evaluate if the questionnaire can assess tobacco uptake and use, and their potential predictors.
Methods
We aimed to conduct a feasibility study of a longitudinal survey in secondary schools in three South Asian countries, Bangladesh, India and Pakistan, involving both quantitative and qualitative data collection. In this section the processes that have already been conducted are described in past tense, and those still to do are described in the future tense. The schools and students have been recruited and baseline data were collected between October 2019 and February 2020 and the data entry is still ongoing(at the time of writing this manuscript). On average the number of investigators was 10–15 per country who conducted the data collection. A questionnaire, to be self-administered, for the students was developed and translated into the local language and checked by a native speaker. A pilot study to check all the arrangements before moving onto the feasibility study was conducted with at least 8–10 students in one school in each of the three counties two weeks prior to the baseline data collection for the feasibility study. We will revise the data collection tools in the light of feedback from the baseline data collection before carrying out follow-up data collection one year after the baseline data collection.We will revise the follow-up questionnaire if needed, based on the responses during the survey on how many students were making queries on some words or sentences from the local language in the questionnaire that they might not understand, and feedback or comments from students about each specific question.
Sampling strategy
We used a multi-stage stratified random sampling strategy to recruit eight schools within each country. We purposively selected two administrative areas in each country, and from each administrative area, we selected one urban and one rural sub-district. From each selected sub-district, we selected schools that met the inclusion/exclusion criteria (Table 1) and then stratified the schools by whether they were public or private and randomly selected one public and one private school from each sub district.
Table 1. Inclusion and exclusion criteria of selection of schools and students.
An invitation letter including brief information about the study was sent to the head teacher of each selected school taking part in the study. Interested schools were provided with a detailed information sheet and consent form. The principal or head teacher of the school provided the written informed consent to participate in the study on behalf of the school. Those schools that provided written informed consent were recruited.
Selecting the sample and recruitment
There are two groups of study participants: school students and schoolteachers which included the headteacher or a representative of the school and class teachers of the classes participating in the study.
In each selected school, three classes (class 6th, 7th and 8th) were selected. The educational system and the age groups of students in class 6–8 (age range between 11 to 16 years) is almost similar in these three countries. We aimed to recruit at least 25 students per class (at least 75 students from each school). As this was a feasibility study, we did not conduct formal sample size calculations. The steps taken to recruit eligible students are shown in Figure 1. First, we prepared a list of eligible students who met the inclusion criteria (Table 1) and excluded those that fell into the exclusion criteria list. Once an eligibility list was prepared by the field investigators with the help of the class teachers, we gave the schools the required number of information packs containing an information sheet, and a parent/carer consent form to proceed with the recruitment. All students participating in this study were under 16 years old and therefore parental/carer consent was required for them to take part. The participating schools sent out the study information packs to the parents of all eligible students.
Figure 1. Stages of recruitment of the students.
We asked parents/carers to discuss the study with their child and to indicate whether they were willing to let their child participate by sending back the signed consent form through the class teacher within one week. At the time of recruitment, children whose parents had provided consent were provided with an information sheet and an assent form so they could make an informed decision whether or not to participate. If students were unwilling, they could inform their class teacher. They were not coerced to consent. Students were asked to sign the assent form if they were willing to participate in the study. All participating students were given an enrolment number (including a code for school), which were recorded on the final list of eligible students and entered in the database.
For the qualitative student component, we used purposive and random sampling to select four schools (two urban, two rural). The intention was to conduct three focus group discussions (FGDs) per school, one per class (6th, 7th and 8th), with a mix of boys and girls. Students were randomly selected, by their class teachers to take part in the FGD, having previously secured parental consent that included the FGD and written assent from the students. Verbal assent was obtained from the selected students before the FGD commenced.
Schoolteachers which included headteacher or a representative of the school and class teachers of the classes participating in the study in all eight schools were approached to participate in a semi-structured interview. They were provided with an information sheet and asked to sign a consent form before the interview commenced. Where possible the class teachers were interviewed together to prompt discussion.
Outcomes to be measured
To address the objectives of the feasibility study, we will assess the following outcomes that have quantitative and qualitative components (Table 2).
Table 2. Objective and outcomes.
Main outcomes (related to objective 1)
Quantitative:
a. Time required to recruit schools and students.
b. Recruitment rates for schools and students.
c. Attrition rates at the first follow-up point for schools and students.
d. Reasons for ineligibility of schools and students.
e. Reasons for non-participation of schools and students.
Secondary outcomes (related to objective 2)
Quantitative: The proportion of completed survey questionnaires.
Qualitative: Student, headteacher and class teacher feedback on feasibility and acceptability of the study procedure and tool (questionnaire).
Secondary outcomes (related to objective 3).
Quantitative: The proportion completing the questions on tobacco uptake and use and potential predictors of the envisaged main study, such as: level of knowledge and awareness on tobacco products and perceived tobacco use norms of the students, exposure to tobacco products, tobacco related health promotion, exposure to tobacco advertisements, perceived ease of access, affordability, and self-reported exposure to other peoples’ tobacco use.
Qualitative: Student feedback on the questionnaire survey items on their tobacco behaviour and perception.
Data collection methods
1. Collection of data from the students.
Quantitative data: The questionnaire included questions from the Global Youth Tobacco Survey (GYTS), Youth Tobacco Policy Survey (YTPS) and International Tobacco Control (ITC) survey questionnaire, and was pre-tested among 8–10 students per country before the baseline data collection. All data collection took place in the classroom. The investigator team visited the school and the pre-tested questionnaire was distributed among the students by the investigating team to all the eligible consenting students present in class. Those who were ineligible or did not give consent were moved to another classroom during data collection. The investigator team members helped the students with any further clarification. The privacy of students answering was ensured without others (classmates) overlooking their responses by giving prior instruction. The schoolteachers were not involved in questionnaire administration and were not present in the classroom during the data collection.
Qualitative data: After baseline data collection, the FGDs with students explored their views and experiences of being informed about the study, discussing the study with their parents, providing assent, and completing the questionnaire.
6–8 students per class took part in the FGD. Topic guides were used to ensure consistency of discussion across schools, although the format was flexible to allow the students to raise additional issues they considered important. The discussions were conducted at the school in a private room by a field investigator and were digitally audio-recorded. The follow-up data collection will be conducted after one year from the baseline data collection. The FGDs during the follow-up data collection will be focused on students’ own and others’ tobacco uptake and use, influences on this to assess the relevance and appropriateness of the questions in the follow-up questionnaire.
2. Collection of data from the headteacher or other school representative and class teachers. After baseline data collection, interviews with head teachers/other school representatives explored their views and experiences of hosting this study in the school. They also provided quantitative data at this time, on general information about the school, e.g. size, number of classes, the school tobacco policy and tobacco selling regulations. The interviews with class teachers focused on the process of informing parents and students about the study, organising consent, assent and survey administration. The field investigators conducted all interviews, which were digitally audio-recorded.
In addition, a logbook was maintained by each country throughout the process to record the time required to recruit schools and students, reasons for ineligibility of schools and students, and reasons for non-participation of schools and students.
Data analysis
Quantitative data. For the feasibility assessment, we will report recruitment, retention and attrition rates, percentage of completed questionnaires, missing data and summarised follow-up time. We will provide a diagram of flow of participants at baseline and at first follow-up. In addition, we will carry descriptive analyses for each phase of data collection. We will report the characteristics of students (e.g. demographic, socio-economic status, tobacco use) and information on tobacco uptake, and potential exposures. The questionnaire used for the survey incorporates the questions related to tobacco uptake and potential exposure. We will provide frequency and proportion for categorical variables and means and standard deviations for continuous variables. If a variable is skewed, we will provide medians and interquartile ranges and use graphical representation where appropriate. We will use STATA 16 (2019) to carry the statistical analysis.
One of the objectives if the study is to assess attrition rates (Objective 1-c). Due to practical considerations, students who move to another school due to higher educational stage will not be followed up. Longitudinal analysis techniques can accommodate varying follow-up points per participant.
Quantitative data. The interviews and FGDs were transcribed verbatim and translated into English. A categorization matrix for each data set (head teachers/class teachers/students) was developed, organized by the steps of the study procedure. The data from the three countries has been coded into the same matrix, using Excel software (Microsoft, 2018). The data analysis will be conducted using deductive content analysis (Elo & Kyngäs, 2008).
Ethical issues relating to the study and ethical approval received
In order to protect the study participants, the following provisions have been made/upheld:
Recruitment
The most appropriate approaches to recruiting participants into the study were carefully considered. In addition, investigators involved in recruitment of study participants underwent suitable training and be provided with appropriate support. In order to ensure that participants of this study do not feel any inappropriate pressure or coercion, cautious attention was given to all recruitment procedures and materials.
Consent
Consent forms and information sheets was carefully prepared and appropriate procedures were planned, in order to obtain a full-informed written consent in an acceptable and suitable manner. The participants acquired sufficient information and had the capacity to make the decision on whether to take part in the study. Furthermore, those participating in the study were informed of the right to stop their participation at any point throughout the study. It was mentioned in consent and assent form that participants were free to withdraw any time as per their wish without showing any reason. In that case, no more data would be collected. The information already collected will be kept secure and still used in the analysis unless the participant specifically asks for the information to be removed. Additionally, it was made very clear that participation, withdrawing from the study or not participating at all would not affect participants’ school results in any way
Risk, burdens and benefits
All research projects carry certain risks and burdens for the participants. Although this study does not involve any invasive procedures, it concentrates on tobacco use issues that potentially are of sensitive nature. Participants may have concerns about the risk of disclosure of their tobacco consumption practices and/or any breaches of confidentiality concerning their data or information provided. Careful consideration was given in order to minimize the potential risks and burdens to participants. While developing the procedures and policies, every effort was made to reduce participants’ feeling of shame, guilt and pressure. Furthermore, attention was given to minimize participants’ time involvement. Additionally, the investigators participating in the study were appropriately trained and supported to decrease any burdens of taking part in the study. Consideration was given to avoid any pressure or coercion. Teachers were not involved in the process of quantitative data collection from students, and they were not present in the classroom during data collection as their presence might develop insecurity among students to answer honestly to fill in the questionnaire.
Confidentiality
Every effort was undertaken to ensure confidentiality at all times throughout the study, including its design, conduct and reporting of the results. This study strictly followed ethical principles governing confidentiality. Participation in this study was anonymous so any name or any identifiable details would not be disclosed. The questionnaires were identifiable and were coded with a study enrolment number. The participants were assured that no names would be associated with the data, which would be kept in a locked secured facility. The data collection was monitored by the investigators to ensure that no participant can view another participant’s responses in the questionnaire to maintain confidentiality.
Provision was made for indemnity by the investigator and sponsor.
The study obtained formal ethics review and approvals from the University of York (4-87/NBC-355/19/1695), the Indian Council of Medical Research (HMSC approval proposal ID 20182675, dated 13/04/2019', Bangladesh Medical Research Council (BMRC/ NREC/2016-2019/969, dated 07/01/2019.), National Bioethics Committee Pakistan (NBC: 4-87/NBC 355/Amend+Extension/20/1990?, dated 28/02/2019), and institutional level approval from Maulana Azad Medical College and associated hospitals, India; Aga Khan University, Karachi and, Khyber Medical University, Peshawar sites. Approvals from the participating school administrations have been obtained.
Data protection
Appropriate data protection and security procedures are put in place. Identifiable information was collected on the consent form in order to be able to match the students in the follow-up data collection. Identifiable information collected on the consent form and codes were stored separately from the questionnaires. Interview and FGD (related to the qualitative data collection) data were entered using the IDs allocated to the schools and student participants and also kept separate from the codes.
All information collected during the course of the study was kept strictly confidential and will only be available to those involved in the research. Information was held securely on paper and electronically at the central research office. Any digital data was accessed only through use of security passwords. The researchers also complied with all aspects of related Data Protection Acts.
Plans for dissemination of the findings once completed
We will disseminate the findings to academic audiences via publication in open access, high impact, and peer-reviewed scientific journals of relevant discipline and via related scientific presentations at national and international conferences and seminars. We will also disseminate to non-academic audiences, like national and regional stakeholders for tobacco control in SEARO and EMRO regions, community representatives and local administrations and participating schools and families.
