Methods: To achieve the goal of this research, we have carried out the survey on the total of 248 mothers of kindergarten children in Gyeonggi-do area, And T-test, Analysis of variance, Simple correlation analysis, Multiple regression analysis were used to analyse the date with SPSSWIN 17.0. Results: 1. Health care behaviors-related factors from among general characteristics were statistically significant depending on the degree of economic levels of the household(F=5.072, p=.016), occupation of the mother(F=2.068, p=.040) and health status of the children(F=6.651, p=.002). 2. Health care behaviors-related factors from the use of internet health information were statistically significant depending on the degree of child care/health informer (F=2.063, p=0.041), frequency of the usage(F=5.803, p=.003 ), the number of sites(F=19.400, p=.000), methods of research(F=3.668, p=.027) and information providers(F=7.952, p=.000). 3. It is found out that there is medium level of positive relationship(C.C.=.434, p=.000) between the usage of internet health information and health care behaviors. The higher the quality of internet health information is, the more health care behaviors increase. 4. It is found out that the information(β=.294, p=.000), the numbers of site(β=.251, p=. 000), information providers(β=.153, p=.043), economic level of the household(β=.147, p=.007) and child`s health status(β=.125, p=.021) have effect on health care behaviors.
