| 总结: | Background: More than two billion people are expected to lack essential
vitamins and minerals, especially vitamin A, iodine, iron (Fe) and zinc (Zn).
Research showed the positive effect of zinc supplementation on children's growth,
morbidity and mortality in diarrhea and pneumonia. Zinc plays an important role
in the structure and function of the brain, so that zinc deficiency can also harm
behavior in the development of cognitive functions, namely attention and
memory.
Objective: To determine the effect of zinc deficiency on memory in school-age
children in the district of Klaten.
Method: The study used was description of analytic with quantitative approach
using cross-sectional design. The experiment was conducted in some primary
schools (SD) in the district of Klaten. The study population was all primary school
children aged 9-12 years which the sample accordance with inclusion and
exclusion criteria. The sampling technique was done by purposive sampling to
represent SD of villages and towns. The determination of the samples by PASS
software and the number of sample was 60. Data analysis used univariable,
bivariable and multivariable by statistical test t-test and linear regression with
95% confidence intervals.
Results: The analysis showed that children with zinc deficiency has the average
value of 6.1 short -term memory with SD 1.3, whereas children with normal zinc
levels had the average value of 10.7 and SD 3.1. The mean difference of -4.6 with
95 % CI (-6.98 - (-2.14) and a value of p = 0.0004 or p < 0.05. Children with zinc
deficiency the average value of long-term memory were 7.8 with SD 3.0, whereas
children with normal zinc levels the average value was 8.4 and SD 3.2. The
difference of the mean was -0.57 with 95 % CI (-3.16 - 2.01) and a value of p =
0.658 or p > 0,05.
Conclusion: The average scores value of short-term memory in children with zinc
deficiency was lower than the short-term memory scores in children with normal
zinc levels. The average scores value of long-term memory in children with zinc
deficiency equal to the children with normal zinc levels.
