Emotional eating: A treatment-worthy construct, or artifact of relations between mood and eating behaviors in younger and older women with obesity.

Abstract

Emotional eating (EE) is considered important for controlling weight, especially in women; however, it might be affected by age. Within a recently proposed model assessing theoretical paths from physical activity to changes in psychological variables and then eating behavior and weight, it was unclear if EE was a construct requiring specific treatment attention or if attending to effects of physical activity-induced mood changes on eating was sufficient. Women with obesity of >35years-of-age (n=100) and ≤35years (n=44) participated in a behavioral weight loss treatment and were assessed on psychological factors and physical activity and eating behaviors over 6months. At baseline, the younger group demonstrated significantly higher scores on physical activity and depression, and significantly lower scores on fruit/vegetable intake. Improvements in Tension (i.e., anxiety), Overall Negative Mood, and dimensions of EE from baseline-Month 3 were significantly greater in the younger group. Similar significant improvements in physical activity and the intake of sweets and fruits/vegetables over 6months were observed in both groups. Incorporating aggregated data, change in physical activity was significantly related to mood improvements. With the exception of EE related to Anger/Frustration, changes in dimensions of EE and Overall EE significantly mediated the prediction of sweets and fruit/vegetable intake by corresponding dimensions of mood and Overall Mood. Age group significantly moderated embedded relationships between changes in Overall EE and EE-Anxiety and change in fruit/vegetable intake, with the older age group having stronger relations. Findings suggest that EE is a construct requiring distinct attention within behavioral obesity treatments.
