Invited commentary: comparison of food frequency questionnaires

Article Abstract:

The comparison of three dietary assessment methods among 101 obese women by Patricia Elmer, Elisabeth Wirfalt, and Robert Jeffrey provided a mean correlation of .60, but the Block questionnaire underestimated energy sources and Willet questionnaire overestimated nutrients from fruits and vegetables. The study was not designed to compare questionnaire methods and the 3-day surprise telephone recalls provided a weak but ideal assessment.

Previous lung disease and risk of lung cancer among men and women nonsmokers

Article Abstract:

Researchers between 1982 and 1984 conducted a population-based case-control study of lung cancer among men and women nonsmokers in New York. They interviewed 437 lung cancer cases and 437 matched population controls. They found statistically significant associations for emphysema, chronic bronchitis, and asthma. The risk remained high for older subjects who were diagnosed.
