The objective of this paper was to determine the prevalence and sources of high lead (Pb) exposure among children in Bulacan, Philippines. A total of 150 children (6-7 years old) and their caregivers were studied. Lead was analyzed in children hair and deciduous teeth. Sources of lead exposure were determined by caregiver interview and Pb analysis of house soil, drinking faucet water, air, and water from seven Bulacan rivers. Lead was positive in 91.3% of children's hair (MC or median concentration = 8.9 μg/g; range = 0-38.29), in 46.2% of the teeth (MC = 0.000 μg/mg in positive samples; range = 0.00-0.020), in 100% of soil (MC = 27.06 mg/kg; range = 3.05-1155.80), in 21.1% of air (MC = 0 μg/Ncm; range = 0-0.10), in 4% of house, faucet water (MC = 0.0 ppm; range = 0-40). There was a significant correlation (Spearman's rho) between Pb in children's hair and soil (r = 0.195; p = 0.017) and between Pb in house water and outdoor air (r = 0.616; p = 0.005). There is no significant correlation between Pb in children's hair and teeth. None of the potential sources of Pb from interview were related to lead exposure in the children. Water from seven Bulacan rivers was 100% positive for lead (MC = 70.00 ppb; range = 30-90). Widespread flooding with river overflow occurred in Bulacan in 2009 which likely caused lead contamination of the soil. There was no significant difference in the lead concentration of the soil whether near or far from the river (p = 0.205, Mann-Whitney U test). High lead exposure in children in Bulacan is likely from soil contaminated by lead-polluted rivers during flooding. In areas where flooding is common, alluvial and riparian soils from polluted rivers are important sources of lead exposure in children.
Objective. To determine the effectiveness of Kangaroo Mother Care (KMC) in increasing the rate of weight gain and decreasing hypothermia, apnea, and sepsis rate, and shorten hospital stay among low-birth-weight infants. Methods. Very low birth weight (VLBW) infants (≤1500 grams) were randomized to either the KMC or conventional care group. KMC provided skin-to-skin contact at least 6 hours per day while the conventional group received the usual care in the newborn intensive care unit (NICU). Daily weight measurements and weekly measurements of length, head, and chest circumference were recorded until discharge. Occurrence of hypothermia, apnea, sepsis, and length of stay was noted. Results. KMC group had a higher mean weight gain per day (p=0.0102). There was no difference in the length, head, and chest circumference between the two groups. Sepsis and apnea rates were not significant between the two groups. Significantly more neonates experience hypothermia in the control group (p<0.0069). Conclusion. KMC is effective in increasing the weight per day compared with the control group. KMC protects the neonates against hypothermia. There is not enough evidence to show a difference in the incidence of sepsis, apnea, and the length of hospital stay between the two groups.
