Abstract
Pregnant women in different trimesters of pregnancy were divided into control (n = 58) and study (n = 104) groups. Study group subjects were given 45 mg zinc/p.o./day as 200 mg 'zinc sulphate tablets from the day of reporting till term. Body zinc status was clinically assessed by 'zinc taste test'. Blood samples were drawn at the same time and serum zinc levels measured. Zinc taste test scores decreased with advancement of pregnancy (P < 0.05) and increased significantly following zinc administration (P < 0.05). Serum zinc level declined significantly with advancement of pregnancy (P < 0.001). Following zinc administration, serum zinc level increased significantly (P < 0.001). Accuracy of zinc taste test in individual cases ranged between 70 and 100 percent. On the whole, zinc taste test was well correlated with serum zinc level, and provides a fair idea of zinc deficiency.
