The aim of this study was to analyze different communities' interest in seeking obesity, smoking, and alcohol-related terms through relative search volumes (RSVs) of Google Trends (GT). Internet search query data on obesity, smoking, and alcohol-related terms were obtained from GT from the period between 2010 and 2020. Comparisons and correlations between different topics were calculated considering both global searches and English-, Spanish-, and Italian-speaking areas. Globally, the RSVs for obesity and alcohol-related terms were similar (mean RSVs: 76% and 77%), but they were lower for smoking (65%). High RSVs were found in winter for obesity and smoking-related terms. Worldwide, a negative correlation was found between alcohol and smoking terms (r = -0.72, penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Google Trendsalcoholismdietlifestyle behaviorobesitysmokingresearch article33572379open access10.3390/healthcare9020190PMC7916197https://www.mdpi.com/2227-9032/9/2/190/pdf?version=1613729855https://pmc.ncbi.nlm.nih.gov/articles/PMC7916197/pdf
