Abstrakt: Purpose: Due to the increasing prevalence of overweight and obesity with age and associated health risks, older adults are an important target group to promote healthy weight. Evidence indicates that maladaptive eating behaviors are associated with higher BMI. However, older adults are often neglected in this research field. This prospective study aims to clarify the temporal relationship between BMI and maladaptive eating behaviors among older adults.
Methods: In total, 964 participants of the NutriAct Family Study (M age  = 63.34 years) completed web-based questionnaires two times (M = 3.33 years apart). BMI was assessed via self-reported height and weight, and maladaptive eating behaviors with the Dutch Eating Behavior Questionnaire (DEBQ). The stability and longitudinal associations were analyzed using cross-lagged models.
Results: Cross-sectional analysis showed positive correlations between BMI and emotional (r = 0.218), external (r = 0.101), as well as restrictive eating (r = 0.160). All maladaptive eating behaviors (β > 0.684) and BMI (β > 0.922) were longitudinally stable. No significant bidirectional relationships were found between BMI and maladaptive eating behaviors over time, except for BMI predicting restrictive eating (β = 0.133).
Conclusion: The observed cross-sectional, but not longitudinal associations between BMI and maladaptive eating behaviors underline the need for prospective study designs to deepen the understanding of the role of maladaptive eating behaviors in weight management among the general population. Maladaptive eating behaviors among older adults may have already consolidated and play a smaller role in explaining weight course, compared to early life like childhood.
