Using air quality monitoring to reduce second-hand smoke exposure in homes: The AFRESH feasibility study.

ABSTRACT: INTRODUCTION:Few interventions to reduce second-hand smoke in homes where children are present have been successful. A novel intervention was developed that included personal air-quality feedback. This study aimed to evaluate the feasibility and acceptability of delivering this theory-based intervention through small third-sector organisations in deprived areas within Scotland. METHODS:The setting was third-sector organisations in Scotland. Support workers used air quality monitors to give information on smoke-free homes to parents. This advice was structured around computer generated reports, co-developed with workers and target-group members. Participants received a monitor then received a report, which was discussed with a support worker. Two weeks later, the monitor was reinstalled and another report produced to evaluate success. Three participants and one support worker were interviewed afterwards to explore their experiences. RESULTS:One centre out of six that were approached agreed to deliver the intervention. Four participants took part. All participants saw a decline in average concentrations of PM2.5 in their homes. In interviews, the participants and the support worker indicated that the intervention was acceptable and useful. The centres that declined to participate in the study cited a range of reasons, including a lack of staff time and perceived difficulties in recruiting members of the target population. CONCLUSIONS:This intervention was acceptable for the target population tested, and may help participants to create smoke-free homes, although it is not possible to generalise the results of this small study. However, the resources required for the delivery of AFRESH do not match with the resources available in third-sector organisations, despite smoke-free homes being a policy priority.

Project description:BackgroundSecond-hand smoke (SHS) is a serious health hazard costing 890,000 lives a year globally. Women and children in many economically developing countries are worst affected as smoke-free laws are only partially implemented and homes remain a major source of SHS exposure. There is limited evidence on interventions designed to reduce SHS exposure in homes, especially in community settings. Following a successful pilot, a community-based approach to promote smoke-free homes in Bangladesh, a country with a strong commitment to smoke-free environments but with high levels of SHS exposure, will be evaluated. The study aims to assess the effectiveness and cost-effectiveness of a community-based intervention, Muslims for better Health (M4bH), with or without Indoor Air Quality (IAQ) feedback, in reducing non-smokers' exposure to SHS in the home.Methods/designBased on behaviour-change theories, M4bH and IAQ feedback are designed to discourage people from smoking indoors. M4bH consists of a set of messages couched within mainstream Islamic discourse, delivered weekly by faith leaders (imams and khatibs) in mosques over 12 weeks (one message each week). The messages address key determinants of current smoking behaviours including lack of knowledge and misconceptions on specific harms associated with SHS exposure. IAQ feedback consists of personalised information on IAQ measured by a particulate matter (PM2.5) monitor within the home. Following adaptation of M4bH and IAQ feedback for the Bangladeshi context, a three-arm cluster randomised controlled trial will be conducted in Dhaka. Forty-five mosques and 1800 households, with at least one smoker and one non-smoker, will be recruited. Mosques will be randomised to: M4bH and IAQ feedback; M4bH alone; or usual services only. The primary outcome is 24-h mean household concentration of indoor fine particulate matter (PM2.5) at 12 months post randomisation. Secondary outcomes are 24-h mean household PM2.5 at 3 months post randomisation, frequency and severity of respiratory symptoms, health care service use and quality of life. A cost-effectiveness analysis and process evaluation will also be conducted.DiscussionThe MCLASS II trial will test the potential of a community-based intervention to reduce second-hand smoke exposure at home and improve lung health among non-smokers in Bangladesh and beyond.Trial registrationISRCTN, ISRCTN49975452 .
