Determinants of plumbun level in blood among elementary school students in cinangka, bogor

Plumbun is one of toxic heavy metal that can decrease hemoglobin and IQ, affect the digestive, cardiovascular and reproduction system. In Cinangka Village (Bogor), plumbun pollution on the ground reached 270,000 ppm (WHO threshold = 400 ppm). The purpose of this study was to analyze the determinant factors of plumbun level in blood among elementary school students in Cinangka. This research was an analytic survey with cross sectional design. To measure plumbun, blood samples were taken from 103 students in Cinangka (2014). Independent variables consist of location of residence, parent’s education, nutrient intake were known by using questionnaire. The measurement of nutritional status was known by calculating Body Mass Index. Statistical analysis with Mann-whitney test showed there was mean difference in plumbun level between students who living in Cinangka villages and outside Cinangka Village (p=0.004). For mother’s education, there was mean difference in plumbun level between students who had mother with low education and high education (p=0.032). There was not mean difference in plumbun level for father’s education (p=0.250) and nutritional status variable (p=0.145). Rank spearmen correlation test showed there was correlation between intake of potassium (p=0.05;correlation coefficient=-0.191), calcium (p=0.05;correlation coefficient=-0.192) and zinc (p=0.05;correlation coefficient=-0.194). There was not correlation between intake of iron (p=0,107) and protein (p=0.080) with plumbun. Determinant factors of plumbun level in this study were location of residence, mother’s education, intake of potassium, calcium and zinc. Variable of father’s education, nutritional status, iron and protein intake were not determinant factors of plumbun level.
