The Association between Citrus Consumption and Melanoma Risk in the UK Biobank.

Publication date: Mar 30, 2021

Melanoma incidence has been dramatically increasing worldwide. Psoralen, a known photocarcinogen, is naturally abundant in citrus products, leading to the hypothesis that high citrus consumption may increase melanoma risk. To investigate the association between total citrus consumption and melanoma risk, the association between individual citrus products and melanoma risk, and test for interactions between total citrus intake and established melanoma risk factors. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between citrus consumption and melanoma risk among 1,592 cases and 197,372 controls from the UK Biobank cohort. Citrus consumption data were collected via 5 rounds of 24-hour recall questionnaires. International Classification of Disease codes were used to determine melanoma outcome. After adjusting for potential confounders, participants in the highest category of total citrus intake (>2 servings/day) had a significantly increased risk of melanoma (OR [95% CI] = 1. 63 [1. 24-2. 12]) relative to those with no consumption. For individual citrus products, participants with the most orange and orange juice consumption (>1 serving per day) had a significantly increased melanoma risk relative to those with no consumption (ORs [95% CIs] = 1. 79 [1. 07-2. 78] and 1. 54 [1. 10-2. 10]), respectively. Fair/very fair-skinned participants with high citrus consumption had an even greater melanoma risk (OR [95% CI] = 1. 75 [1. 31-2. 29]). High citrus consumption was associated with an increased risk of melanoma in a large, prospective, population-based cohort. Further validation of these findings could lead to improved melanoma prevention strategies.
