Abstract

Background/Objectives: Obesity, food and nutrient intake, and physical activity (PA) have been linked to the occurrence of various types of cancer. However, evidence regarding their relationship with melanoma is limited. We aimed to assess whether body mass index (BMI), diet quality, food cooking methods, and PA influence the risk of developing melanoma. Methods: This case–control study compared the demographic characteristics, dietary habits, and PA of 130 melanoma patients from the Hospital Clínic de Barcelona with 166 control subjects of similar age and sex distribution. Data was collected by means of a questionnaire, administered between January 2016 and February 2020. The association between these factors and melanoma was assessed using odds ratios for binary variables with 95% confidence intervals. Results: BMI was not found to be associated with the diagnosis of melanoma. However, restricting foods and limiting sugary products did show a correlation with lower melanoma risk, while dairy product restriction was associated with an increased risk. Consumption of processed meats and unhealthy cooking methods were also associated with an increased risk of melanoma development. Lastly, an inverse association between PA practice and frequency and melanoma risk was observed in women, while vigorous-intensity PA showed an inverse association regardless of sex. Conclusions: This study identifies specific dietary patterns and PA behaviors that may play a role in melanoma risk, highlighting the potential for personalized lifestyle-based prevention strategies.
