[A cross-sectional survey on the efficacy of 'China Healthy Lifestyle for All' in 2012].

OBJECTIVE: To study the efficacy of 'China Healthy Lifestyle for All' (CHLA).

METHODS: Under similar GDP status, two counties(one with CHLA and one without)were randomly selected from each province of China. Cluster randomized sampling method was performed to select 500 over 18-year-olds from each county. Face-to-face questionnaire interview was used to collect data related to knowledge, awareness and behavior on healthy lifestyle. Generalized Estimated Equation was fitted for the multi-factor analysis.

RESULTS: A total of 31 396 subjects were surveyed, with 11 871 urban and 6312 rural residents from counties that had under gone the CHLA. Another 3934 urban and 9279 rural subjects were from those counties that had not carried out the CHLA(as control group). In both urban and rural areas, the CHLA group seemed more likely to be aware of the Campaign itself and the knowledge on healthy lifestyle, than the control group as well as consciously limiting the salt and oil intake, after adjusting other factors such as county, gender, age and education. In the urban area, rates of awareness on the Campaign in both the CHLA and control groups were 57.1% and 31.7% (OR = 3.33, 95% CI:1.63-6.80, P = 0.001)respectively. And in the rural area, the rates of consciously limiting the salt intake in the CHLA group and in the control group were 51.5% and 38.8% (OR = 1.70, 95% CI:1.13-2.56, P = 0.011)respectively. In the urban area, subjects from the CHLA group were more likely to use the healthy supportive tools than the control group. Rates of using salt measuring spoons in both the CHLA group and control groups were 49.2% and 29.5% (OR = 2.46, 95% CI:1.45-4.17, P = 0.001) respectively. In the rural area, statistically significant difference was only found in the rate of using scaled oil pots(OR = 2.11, 95% CI:1.09-4.09, P = 0.028)between the CHLA group and the control group. In the rural area, the CHLA group was more likely to engage in more physical activities than the control group. No differences on the rates related to physical activities were found in the urban area. Some behavioral indicators such as the rates of consciously maintaining the body weight, daily intake of vegetables and fruits showed no statistically significant differences between the CHLA group and the control group either in the urban or in the rural areas.

CONCLUSION: The 'China Healthy Lifestyle for All' seemed to have improved the knowledge on awareness and consciousness of healthy lifestyle. However, the effect of CHLA on the healthy behavior needs to be further evaluated.
