As indicated, the calcium deficiency among students, whether primary school or high school ones, is alarmingly high. For the boys of first 3 grades in primary school, the number of those with calcium deficiency is 43, which accounts for 43. 88% of the total boys surveyed. For the girls, the number is 74, which accounts for 68. 52% of the total girls surveyed. And the number for 6 grades in primary school is 57, 65. 52% (boys) and 41. 64. 06 % (girls) respectively, while comparatively, for the students in middle school, the number is a little lower. For the boys in junior high school, the proportion of those with calcium deficiency is 63. 64 %, whereas the proportion for the girls is 59. 52%. The numbers of the boys and the girls in senior high school with calcium deficiency are the lowest: 45. 45% of the boys surveyed are with calcium deficiency, and for the girls, only 40. 00%. Therefore, more attention should be paid to calcium deficiency among students, especially the primary school students and junior high school students. Thus, the number of those with calcium deficiency can be reduced.
