The relationship between weight locus of control, eating behaviors, and anthropometric measurements in menopausal women aged 45–55: a cross-sectional study

Weight locus of control (WLOC), which reflects individuals’ beliefs about weight control, may be an important determinant of eating behaviors and body composition. This study aims to examine the relationship between WLOC, eating behaviors, and anthropometric measurements in menopausal women. The sample for this cross-sectional correlational study consists of 300 menopausal women aged 45–55 living in Alanya. Study data were collected through face-to-face interviews using a questionnaire. The questionnaire included general information and anthropometric measurements, the Turkish version of the Multidimensional Weight Locus of Control Scale, and the Three-Factor Eating Questionnaire. Of the participants, mean body mass index 25.8 ± 6.2 kg/m², and 67.7% had a body fat percentage (BF%) ≥ 25%. In overweight and obese, internal control scores were lower, while uncontrolled and emotional eating scores were higher (p < 0.05). According to the logistic regression analysis, as internal control locus increased, waist-to-hip ratio (OR = 0.888) and BF% (OR = 0.923) decreased, whereas an increase in chance locus (OR = 1.080) and uncontrolled eating (OR = 1.117) was associated with higher body mass index (BMI) (p < 0.05). It was determined that WLOC is associated with eating behaviors and anthropometric measurements in menopausal women. The results highlight the importance of identifying WLOC in menopausal women and tailoring weight management programs accordingly.
