Aluminium level in water supply and health effect (Memory Ability) among housewife at Temerloh / Zulaikha Jannah Amnizar

A cross sectional study has been conducted 100 housewives from two study areas which were selected based on the exposure to high level aluminium and low level aluminium in water supply. The objective of the study was to determine the aluminium level and memory ability among housewives at Temerloh. 100 housewives (n=IOO) have been selected from matching of criteria based on stratified random sampling. Study instruments were included questionnaire, water analyzing were using DR2000 HACH, to asses memory ability by using Neurobehavioral core test battery by World Health Organization (WHO) and Mini Mental Stated Examination. The result showed that the mean aluminium level in water supply at Loji Mempateh (0.129 mg/ L) was significantly difference (t=9.739, p<0.001) higher than Loji Lubuk Kawah (0.00mg/L). It was also found that the different of memory ability between study group and control group was no significantly difference for Digit Span (z= -0.214, p=0.830), Visual Benton Retention (z=-0.574, p=0.566), The Shopping List (z=-0.626, p=0.531), The Name Recall (z=-1.614, p=0.107) and The Name and Face Recall (z=-0.587, p=0.557). The correlation between high level aluminium and memory ability was found that significantly correlation for Digit Span (r= - 0.356, p=0.011), Visual Benton Retention (r=- .306, p=0.031) and The Name and Face Recall (r=-0.291, p=0.041). The two test of correlation between high level aluminium and memory were no significantly; The Shopping List (r=-0.042, p=0.771) and The Name Recall (r=-0.187, p=0.193). This study showed that the aluminium level in water supply influenced memory ability among housewife.
