Nonoccupational determinants of blood leed concentrations in a general population
Re: Hense HW, Filipiak B, Novak L and Stoeppler M. Nonoccupational determinants of Mood leed concentrations in a general population. International Journal of Epidemiology 1992; 21: 75362. The abstract should read as follows:
We investigated the influence of various nonoccupational factors on blood lead levels (PbB) in a sample from the general population of southern Germany. Some 1703 men and 1661 women, aged 2867 years, were examined in the first follow-up examination of the MONICA Augsburg cohort study in 19871988. Their mean PbB was 90 µg/l (SD: 35.9) for men and 65 µg/l (26.4) for women. Only 5% of the men and 1% of all women exceeded a PbB level of 150 µg/l indicating low-level lead exposure in this population. Blood lead was significantly associated with haematocrit values (P < 0.001) and the shape of this association was curvilinear. Per gram of alcohol consumed, intake of beer had a lower impact on PbB than wine, presumably due to differential lead content in these alcoholic beverages. The alcohol-PbB associations were stronger for women than for men. The impact of smoking was generally moderate but again more prominent in women. In particular, the covariate adjusted odds ratios for women of childbearing age (2847 years) to have PbB levels above 100 µg/l were 2.5 (95% confidence interval (Cl): 1.34.7) for smoking versus nonsmoking females, 2.6(95% Cl: 1.16.0) for women drinking up to 40 g alcohol/day compared to abstainers, and 8.9 (95% Cl: 3.225.1) for those drinking more than 40 g alcohol/day. Other factors like age, body mass, rural place of residence, and education or job position, had only minor influences on PbB. We conclude that haematocrit values should always be considered as potential confounders in low-level lead exposure research. High alcohol consumption and cigarette smoking are strongly related to elevated blood lead concentrations in the general population and may thereby convey additional health hazards such as impaired child development or blood pressure elevations. This deserves proper public health recognition.
