Secondhand Smoke Exposure Reduction Among Young Children in China (China SHARE)
Reducing Secondhand Smoke Exposure Among Young Children
Second hand smoking (SHS) is a health hazard to infants and children, in whom it is associated with lower respiratory tract infections, wheezing, cough, middle ear infections and sudden infant death syndrome. Evidence from developed nations suggests that measures to reduce exposure to SHS can improve children's health outcomes; this has not been systematically studied in a developing country setting. The investigators hypothesize that implementation of a package of smoking hygiene intervention measures delivered by community health workers (CHWs) will reduce Chinese children's exposure to SHS and improve their respiratory health.
To test this hypothesis, the investigators have identified three specific aims: (1) to obtain baseline data on second hand tobacco exposure among young children, health status of young children and smoking status of parents and other household members, (2) to generate preliminary effectiveness data for CHW-delivered SHI, and (3) to develop culturally appropriate biochemical measures to assess children's exposure to household SHS. The investigators propose to conduct this study in an urban district in Shanghai, China. After an initial assessment, the investigators will conduct a randomized controlled trial of households in a community, selected based on important study criteria, within the district. The investigators selected this design because it is most likely to produce a scientifically valid answer to our primary study question. All eligible smokers in the intervention group will receive behavioral counseling to address health hazards of SHS towards children, brief advice to quit or to adopt a no smoking policy around children, and educational pamphlets on the hazards of SHS, from a trained CHW in their community. A questionnaire will be used for data collection at the start and at 2 and 6 months. To assess the extent of total SHS exposure, children's urine cotinine (the indicator of nicotine) level will be measured at the first contact and at 2-and 6- months. To validate household members reported level of smoking the investigators will measure air nicotine levels of a sub-sample (10%) of households via passive monitors. The results of this study will provide clinical evidence for the development of CHW-delivered interventions designed to reduce exposure to SHS and improve the respiratory health of children in a resource-poor community. If successful, the program can serve as a model for implementation in other developing country settings. Furthermore, successful results could also be used to draft guidelines for health promotion interventions, which could be implemented as a policy for all primary health care settings. Finally, the study, which would be the first of its type in a developing country setting, will form the basis for future research and program development in the area of SHS.

Grupa uczestników / Arm |
Interwencja / Leczenie |
---|---|
Brak interwencji: Control group
Control group will ONLY receive SHI after completion of the study
|
|
Eksperymentalny: Intervention group
Intervention group will receive smoking hygiene intervention (SHI) at three individualized contacts.
|
The SHI will be delivered in three different individualized counseling sessions: the initial in person counseling (30-45 minutes), at 1 week in person or telephone counseling (15-30 minutes) and at 1 month in person counseling (15-30 minutes).
During the initial counseling, CHWs will emphasize the health hazards of SHS exposure towards young children and its possible illness outcomes.
Then subjects will be asked to assess the SHS exposure of children in the household (e.g., estimating the number of hours for SHS exposure on the child per week or day) and the source of SHS.
The concept of smoking hygiene and non-smoking household policy will be discussed and any potential barriers ascertained.
Furthermore, the CHWs will use the transtheoretical model of Prochaska to assess the stage of readiness of the household member to change smoking behavior existing in the household.
Individuals who wish to quit smoking will receive a brief advice on quitting smoking.
