Emotional overeating mediates the association between depressive symptoms and higher BMI, highlighting emotional eating as a potential therapeutic target in weight-related care.
Obesity and its psychosocial correlates represent an increasing public health concern. Prior international evidence suggests links between depression, anxiety, BMI, and eating behavior traits, yet these relationships remain understudied in Latin American populations. To address this gap, the present study examined associations among depression, anxiety, BMI, and specific eating behaviors, and explored whether eating behaviors mediate the relationship between mental health symptoms and BMI. Data were collected between 2023 and 2024 from 338 Argentine adults (18–67 years, M = 30.8, SD = 12.7; 68.9% women) through an online survey assessing height, weight, clinical information, anxiety (STAI-Trait), depression (BDI-II), and eating behaviors (AEBQ). In the regression model, BMI was positively associated with depression (β = 0.225, p 5.54, p < 0.019). We identified two pathways linking mental health, eating behaviors, and BMI: emotional overeating mediating the association between depressive symptoms and higher BMI, and emotional undereating mediating the association between depression and lower BMI. These findings highlight emotional eating as a relevant therapeutic target; psychosocial approaches such as cognitive-behavioral therapy, mindfulness-based interventions, or acceptance-based strategies may help address maladaptive eating patterns in weight-related care.
