Volume 30, Number 1, January/February 1998 swers into a laptop computer. A revised questionnaire using CAPI was pretested between October and December 1993. About 800 eligible women were selected, and 500 were interviewed. The pretest was an experiment, which compared results for women who received incentives with results for women who did not. Incentives increased response rates, reduced costs...

THE WATER-SOLUBLE VITAMINS represent a structurally and functionally distinct set of organic compounds that are essential for human health. It has long been recognized that they play a vital role in intermediary metabolism, energy production, and cell differentiation and proliferation (1, 4). Mammals, including humans, have lost their ability to synthesize these compounds and, therefore, must o...
