Hazard ratios were adjusted for age (continuous), area (for JPHC-I, JPHC-II only), total energy intake (quintile), smoking status (never, past, <19, 19–39, or ≥40 cigarette/day for men; never, past, or current for women), alcohol consumption (non, occasional, <23, 23–45, or ≥46 g ethanol/day), body mass index in kg/m2 (14–18.9, 19–20.9, 21–22.9, 23–24.9, 25–26.9, 27–29.9, or 30–40 kg/m2), history of diabetes mellitus (yes or no), and screening examination (yes or no; any kind of the following cancer screening for JPHC-I: chest X-ray, sputum test, photofluorography, gastrointestinal endoscopy, fecal occult blood test, barium enema, or colonoscopy; any kind of screening examination for JPHC-II; and chest X-ray, gastric cancer examination, Pap smear, mammography, or complete medical checkup for MIYAGI and OHSAKI). Linear trends across quintiles of fruit and vegetable intake were tested using 0 to 4 for each quintile as an ordinal variable.
