Abstract:
Objective:To understand the trends of smoking and passive smoking exposure in adults in Shaanxi province from 2007 to 2015.
Methods:Data was from China Chronic Disease and Risk Factor Surveillance in 2007, 2010, 2013 and 2015 to calculate the rates of smoking, smoking cessation and passive smoking exposure, as well as the amount of smoking of smokers indicated by each surveillance. Cochran-Armitage test was used to assess the trends across survey periods. The weighting rate was calculated by using sampling weight and data from the 6th national census in 2010. Sensitivity analysis was done to test the trends as well.
Results:The results of the surveillance indicated that the smoking rate in 2007 was 38.26%, highest in the results of four surveys, it decreased to 30.95% in 2013 and then increased to 34.11% in 2015 (Cochran-Armitage test: Z=2.46, P=0.014). The amount of smoking increased from 16.90 cigarettes per day in 2007 to 17.76 cigarettes per day in 2015. The overall rate of smoking cessation was 11.02% in 2007 and 16.95% in 2015 (Cochran- Armitage test: Z=-4.18, P<0.01). We observed the passive smoking exposure rate was 48.10% in 2010 and 63.88% in 2015 (Cochran-Armitage test: Z=-10.60, P<0.01). We found no difference in trends by sensitivity analysis.
Conclusions:The smoking rate and amount of cigarettes smoked in adults in Shaanxi remained stable and at a high level. The rate of smoking cessation increased gradually, while the passive smoking exposure rate increased rapidly.
