Abstract Background: Although blood lead levels in children are gradually decreasing, low-concentration lead exposure can still exert adverse effects. We studied the factors that affect blood lead levels in children in Shenyang, China.Methods: We conducted a cross-sectional study by administering structured questionnaires on family demographics and food intake. The concentrations of lead in venous blood were determined by graphite furnace atomic absorption spectrometry.Results: A total of 273 children aged 1–6 years were enrolled. The geometric mean (geometric standard deviation) of blood lead levels was 24.94 (12.7) μg/L in boys and 23.75 (11.34) μg/L in girls. The prevalence of blood lead levels of ≥50 μg/L was 5.13% and was mainly observed in children aged under 3 years. Frequent hand washing was protective against blood lead levels ≥20 μg/L (adjusted odds ratio: 0.428, 95% confidence interval: 0.238–0.768). Consumption of puffed grains and eggs had an adjusted odds ratio for blood lead levels ≥20 μg/L of 1.714 (1.012–2.901) and 1.787 (1.000–3.192), respectively.Conclusions: In comparison with values recorded 20 years ago, blood lead levels in young children are gradually decreasing in Shenyang. Consumption of puffed grains and eggs is a source of lead. Frequent hand washing may be protective against high blood lead levels.
