- The authors studied how the introduction of several modifications to a basic food frequency questionnaire can influence the results of dietary surveys. Modifications covered eight combinations based on three levels: increasing versus decreasing order of frequency categories; questionnaires without versus with questions about portion sizes, and questionnaires without versus with extra non-dietary questions. The sample included 6783 women between the ages of 40 and 70 years who took part in mammography screening. The women were randomly assigned to one of the eight study groups. All of the women in each group received one of the eight differently modified questionnaires. The forms extended in length by extra non-dietary questions and portion size categories resulted in a 20% higher total non-response compared to the shorter basic form. Partial non-response was significantly lower for all four questionnaire types that included portion sizes. When portion sizes were included in the questionnaire, the reported mean frequency of consumption was significantly reduced for fat (-10 times per month), milk (-6), bread (-5), vegetables (-2) and fish (-0.4). The decreasing order of responses to the frequency categories was associated with a statistically significant increase in the frequency responses for bread (2.6 times per month), vegetables (2) and fish (0.6). These data provide evidence that the design and extension of food frequency questionnaires influence the results of dietary studies.

- In a few previous studies on diet and renal cell cancer, an inconsistent positive association with meat, milk, and protein and a negative association with vegetable and fruit consumption have been found. Whereas earlier studies have dealt with recent diet only, our study explored the effect of foods consumed both during the usual adult lifetime and 20 years prior to interview. The study included 379 individuals with incident histologically verified renal cell cancer and 350 control subjects residing in eight counties in Sweden between June 1989 and December 1991. Usual adult dietary intake and dietary habits 20 years prior to interview were assessed by a structured face-to-face interview and a self-administered questionnaire, respectively. Odds ratios were estimated through unconditional logistic regression. We have not observed an association of renal cell cancer with milk or total meat consumption per se; however, frequent intake of fried/sauteed meat increased the risk of renal cell cancer by about 60%; frequent consumption of poultry was also associated with an increased risk (P for trend, 0.05). A significantly protective effect on risk of renal cell cancer was observed with increasing consumption of fruit (P for trend, 0.05). When analyzed by smoking status, total fruit and especially citrus fruit consumption among nonsmokers showed an even stronger protective effect; the highest quartiles of total fruit, apple, and citrus fruit consumption entailed a 50-60% reduction in risk of renal cell cancer compared with the lowest quartiles. There was a suggestion of a protective effect of high total vegetable consumption. A protective effect of vitamin C and alpha-tocopherol was also more pronounced in nonsmokers (P for trend, 0.004 and 0.007, respectively). Our study adds to the evidence that diet may have an important role in the etiology of renal cell cancer.
