Age-standardized (to World population) incidence of NHL plotted against latitude in 53 populations of mainly European origin (incidence data from ref. 26). Cancer registry populations included are Canada (Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland, Nova Scotia, Ontario, Prince Edward Island, Quebec, Saskatchewan), United States (Los Angeles non-Hispanic White, San Francisco White, Connecticut White, Atlanta White, Hawaii White, Iowa, New Orleans White, Detroit White, New Mexico, Utah, Seattle), Northern Europe (Denmark, Finland, Germany Saarland, Norway, Sweden; Switzerland: Basel, Geneva, St Gall-Appenzell, Vaud, Zurich; The Netherlands Eindhoven; England: Mersey, North Western, Oxford, South Thames, West Midlands, Yorkshire; Scotland), Southern Europe (France; Bas-Rhin, Isere; Italy: Florence, Parma, Torino, Varese; Spain Zaragoza), Australia (New South Wales, South Australia, Tasmania, Victoria, Western Australia, Australian Capital Territory), and New Zealand.

Sun sensitivity characteristics and NHL in the NSW, SCALE and NCI-SEER case-control studies (3, 18)
Sun sensitivity characteristics* OR (95% CI) for highest exposure category NSW SCALE NCI-SEER Blue or gray eyes 1.02 (0.79-1.31) Blue, gray, green, or “mix” eyes† 1.2 (1.1-1.4) 0.54 (0.41-0.71) Blonde, fair, or red hair 0.89 (0.67-1.17) — Blond or red hair 1.0 (0.8-1.1) Very fair skin 1.44 (1.01-2.07) — Light complexion 0.75 (0.41-1.40) Severe burn with blisters on acute sun exposure 1.53 (0.95-2.45) 1.36 (0.63-2.94) Always burns on acute sun exposure 1.0 (0.9-1.2) No tan or freckles only on repeated sun exposure 1.70 (1.06-2.71) — — Heavy facial freckling as a child 1.19 (0.88-1.60) — — ↵* Reference categories in order from top to bottom were - NSW: brown, dark brown, brown or olive, very brown, none; SCALE: brown or black, dark brown or black, seldom burns; NCI-SEER: dark brown, dark, no change; OR for "tan no sunburn" on acute exposure in NCI-SEER was 1.06 (0.53-2.14).
↵† This describes the SCALE category; NCI-SEER OR is for combination of blue and blue-green.

↵† Results were also presented for hours per week in the midday sun during teens, during twenties, and during thirties. The results were similar with ORs trending down to 0.75, 0.75, and 0.78 with ≥28 h of exposure, and Ps are somewhat higher.
