Adult height and risk of breast cancer among white women in a case-control study.

Data from a hospital-based case-control study were analyzed to evaluate the relation of adult height to the risk of breast cancer among white women. The authors compared 5,358 newly diagnosed breast cancer cases and 4,555 controls interviewed from 1976 to 1992 in hospitals located mainly in the United States. Overall, there was no association between stature and risk of breast cancer. In comparison with women whose heights were less than 62 inches (< 158 cm), the adjusted odds ratios were 1.1 (95% confidence interval (Cl) 0.9-1.2), 1.0 (95% Cl 0.9-1.2), 1.0 (95% Cl 0.9-1.1), and 1.0 (95% Cl 0.8-1.2) for women with heights of 62-63, 64-65, 66-67, and > or = 68 inches (equivalent to 158-160, 163-165, 168-170, and > or =173 cm), respectively. There was no consistent evidence of modification of the effect of height by other risk factors. The results suggest that adult stature in white women is not related to the risk of breast cancer.
