Objectives: To assess the blood lead level (BLL) of school children in 10 cities of India. Methods: This multi-centric cross-sectional study enrolled participants from randomly selected schools. Data on demographic details, socioeconomic status (SES) and anthropometric indicators was collected. Samples were collected for assessment of lead level in blood. Inductively coupled plasma-optical emission spectrometry technique was used to assess BLL. Results: From April 2019 through February 2020, 2247 participants were recruited from sixty schools (62.6% government schools) with equal gender distribution. The overall median (interquartile range) BLL was 8.8 (4.8, 16.4) µg/dl. The highest median (interquartile range) BLL was in Manipal 30.6 (23.0, 46.7) and lowest in Dibrugarh 4.8 (3.2, 7.0). Overall, 82.5% of participants had BLL above ≤4 µg/dl. Significant negative correlation was observed between BLL and SES (correlation= -0.24, p <0.001), anthropometric indicators (correlation= -0.11, p <0.001), hemoglobin level (correlation= -0.045, p = 0.03) and multivariate regression model showed association with gender, SES and anthropometric indicators. Conclusions: BLL are elevated in urban school going children and there is intercity variation. Hence, urgent focus is needed to reduce exposure to lead in India. [ABSTRACT FROM AUTHOR] |
