“…The ‘catchment’ areas of cases and controls were similar, participation was practically complete, major identified risk factors, including parity, menopausal status and oral contraceptive use, were consistent with our knowledge of ovarian carcinogenesis [2]and the questionnaire was satisfactorily reliable and valid [11]. Moreover, the model adjusted for age only provides consistent estimates compared with the model including major identified confounding factors as well as with the model including all IGF components.…”

“…Eighty-seven percent of controls were admitted to an orthopedic department and 13% to other departments for miscellaneous illnesses such as eye, nose or throat disorders. Trained interviewers collected information on sociodemographic and anthropometric characteristics, smoking habits, physical activity, height and weight, selected medical conditions, menstrual and reproductive factors and the use of hormone replacement therapy by means of a validated and reproducible questionnaire [11]. Two controls (1.4%) and no cases refused the interview, and one case was excluded from the present analyses due to a history of diabetes.…”

Background: Components of the insulin-like growth factor (IGF) system have been associated with several cancers, but very few studies are available for ovarian cancer. Methods: A case-control study conducted between 1999 and 2003 in Italy, including a total of 59 women with incident, histologically confirmed ovarian cancer and 108 controls admitted to the same hospital network as cases, for acute non-neoplastic diseases. All subjects were interviewed using a validated questionnaire. Results: After adjustment for potential confounders, the multivariate odds ratios for the highest versus the lowest tertile of various IGF components were 0.6 (95% confidence interval, CI: 0.2–1.4) for free IGF-I, 0.4 (CI: 0.1–1.5) for total IGF-I, 2.6 (CI: 0.9–6.9) for IGF-binding protein (IGFBP)-1, and 0.2 (CI: 0.0–0.6) for IGFBP-3. Conclusions: This study suggests a protective role of IGFBP-3 and a positive association of IGFBP-1 with ovarian cancer. The complex role of the IGF system in ovarian carcinogenesis deserves further clarification.

“…A number of other foods, collected through the open questions, contributed to a lower extent to total retinol and carotenoids intake. The FFQ was reproducible and satisfactorily valid [17,18]. The Pearson correlation coefficients were 0.70 for reproducibility and 0.61 for validity of information on energy intake.…”

“…The FFQ originates from a validated and reproduced instrument (Franceschi et al 1993(Franceschi et al , 1995Decarli et al 1996) that was used in a series of multi-centre case-control studies carried out in Italy Negri et al 2000;Bidoli et al 2001Bidoli et al , 2003Bidoli et al , 2005. This original instrument was adapted to reXect the dietary consumption patterns reported in the study population (Babinska and Bederova 2002; Statistical OYce of the Slovak Republic 2002; Mihailescu et al 1981;Biro 1992).…”
