The Linkages Between Knowledge, Attitude And Practice Regarding Nutrition And Food Safety In The Age Sequence

Objective: To explore the linkages between “ knowledge, attitude and practice”(KAP) regarding nutrition and food safety in the age sequence, and understand the application conditions of KAP model in eating behavior change model, and provide guidance to science outreach activity, health education, etc.Methods: The KAP scale was self made, and improved by expert evaluation and pre-survey. The survey was divided into the field investigation and the network investigation, and the contents is completely consistent. Age sequence was divided into 5 age groups: including 10-15 years old, 16-18 years old, 19-24 years old, 25-34 years old and above 35 years old. Field survey adopting multistage and stratified sampling and objective sampling method, and investigated selected two middle schools, 2 vocational schools, 3 University, part of the community. The so jump was use to conducted the Network investigation, and promote the network survey through a variety of ways, such as the issuance of leaflets, post the posters, as well as the proliferation of We Chat or QQ. We using the Epidata input the field questionnaire data; the network survey data was download from the so jump. After collected all the data, we analyzed it by SAS 9.2.Results: Through the network and field investigation, we collected 3170 valid questionnaires(92.8% efficiency). The KAP score of all subjects was 66.8 ± 14.9, 73.1 ± 12.5, 73.2 ± 10.4, and women scored higher than men. The scores of dietary behavior is relatively low in Chongqing residents, such as breakfast, sugary drinks and grilled food intake. The last 7 days, only 19.5% of the 19-24 years old residents have breakfast everyday, 92.4% of the 16-18 years old residents drinking sugary drinks more than 3 times; 4% of the above 25 years old residents eat fried foods or barbecue everyday. We analyzed the KAP scores in age sequence, we found that the 25-34 years old residents’ knowledge score in the age sequence scored the highest in knowledge(74.4±12.1); above the 35 years old scored the highest of attitude(83.5±15.0); 10-15 years old scored the highest in practice(76.2±9.8). And with the growth of the age, the scores of knowledge is gradually increased, around 35 years old reached its peak, but after gradually began to decline, and attitude scores is showing a trend of growing, behavior scores decreased from 10 to 35 years old, and after slightly rebounded. The KAP linkages between different ages as follows: overall, the correlation between knowledge and attitude scores was increased with the age, but the correlation between attitude and behavior, knowledge and behavior were downward trend. And in the age sequence, the correlation between attitude and behavior was the highest, and the correlation between knowledge and behavior was the lowest.Conclusion: The KAP scores of Chongqing residents did not meet the requirements of “the national health education and health promotion work plan(2005 ~ 2010)”, we should conduct some health education activity, and focus on the male, the contents of education could be in view of the low score of knowledge and behavior, and focuses on explaining the serious consequences brought about by the bad eating habits. The survey found that with the change of age, correlation coefficient between KAP also changed, if applied the KAP model in some age may have few effects, or even opposite. In 10-15 years old, knowledge had a higher correlation with behavior, applied the KAP model to conducted health intervention may achieve good results, and above 35 years old, due to the correlation coefficient between knowledge and behavior is negative, KAP model application was limited, possibly will appear opposite results. But in this age group, the social cognitive theory, health belief model and other behavior change models which are mainly concerned about the change of the belief model can get better results than the KAP model. Therefore when we conducted health education work in the future, it should be according to the linkage of KAP between different age, and adopted specific measures to improve the bad behavior according to their age.
