Introduction: People who live in highly allergenic regions have a greater risk of being sensitized; therefore, these areas have a higher prevalence of mono and polysensitized patients. The aim of the present study was to investigate the allergen sensitization profiles in patients with asthma in an agricultural zone in Mexico. Methods: An analytical cross-sectional study was conducted in a secondary care hospital in Obregon City, Mexico. The allergen sensitization pattern profiles were analyzed through a skin prick test (SPT) in 294 patients. Data was collected before SPT: asthma control was classified according to the Global Initiative for Asthma Criteria, nutritional status was assessed with the Body Mass Index (BMI) using Quetelet’s index (BMI = weight/height2), and comorbidities, asthma, and smoking habits were collected from the patients’ medical records. Results: In this study, in a group of adults with asthma, the prevalence of sensitization was 77%. The most frequent categories of aeroallergens were in indoors, in zones with weeds and abundant trees. A low proportion of monosensitized patients (2%) was observed. House dust mites were the most common allergens. Conclusions: Our study describes the sensitization pattern among asthma patients. This study will help identify the panel of most common allergens in this region of Mexico, and aid in selection of specific treatment through immunotherapy.
