Nutrition knowledge scores and nutrition altitudes scores increased with subjects′increased level of perception of the importance of acquiring nutrition knowledge and nutrition information. There was a highly significant correlation between the degree of health consciousness and dietary habit score (${gamma}$ : 0.3, p<0.001). The degree of health consciousness was also significantly correlated (${gamma}$=0.6, p<0.001) with nutrition attitudes scores. But the correlation between the degree of health consciousness and nutrition knowledge was not statistically significant. The degree of the perception of the importance of nutrition knowledge showed a positive correlation with nutrition attitude (${gamma}$:0.4, p<0.001) and dietary habit (${gamma}$:0.3, p<0.001). The degree of perception about the importance of nutrition knowledge and nutrition information was positively correlated with nutrition knowledge (${gamma}$:0.2, p<0.001) and nutrition attitudes (${gamma}$:0.3, p<0.001).
