Smoking Clinical Trial - A Cluster-RCT of SHS Among Primary School

Status Completed

Clinical Trial Summary

This is a school- and family-based prospective trial among Primary/Grade 2-4 (P2-4) students in randomly selected 12 schools in Hong Kong. This study will assess the intervention effects on children's exposure to environmental tobacco smoke (including SHS and THS at home, SHS at home from neighbours and SHS outside home), children's SHS-related knowledge and attitude, intention to smoke, respiratory symptoms, parents' smoking cessation, and family happiness.

Clinical Trial Description

Around 12 primary schools in Hong Kong will be randomly selected and recruited and the 3 grades (P2-4) in each of the recruited schools will be randomly allocated to intervention or control arms. After the consenting process and baseline survey, we will conduct a 3-month intervention and then 2-month boosters which include 8 worksheets, around 15 online question quizzes and 30 WhatsApp messages. After 3-month and 6-month follow-up periods, we will assess the differences of children's exposure to environmental tobacco smoke (including SHS and THS at home, SHS at home from neighbours and SHS outside home), children's SHS-related knowledge and attitude, intention to smoke, respiratory symptoms, parents' smoking cessation, and family happiness. According to the results of baseline survey, we will also invite all the students exposed to SHS at home to provide their hair samples before intervention and at the 6th month in order to obtain objective results (hair nicotine measurements).

Aims of this study: (1) To reduce children's exposure to environmental tobacco smoke. (2) To reduce objectively measured exposure to tobacco smoke (hair nicotine) among children who are exposed to SHS at home at baseline. (6-month, laboratory test). (3) To promote SHS-related knowledge and attitudes, and avoidance of SHS among children. (4) To reduce children's intention to smoke. (5) To reduce children's respiratory symptoms. (6) To promote smoking cessation (past 7 days) of parents. (child report) (7) To promote children's perception of family happiness. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
