RESUMO
The Protective Role of Self-Regulation for HRQOL of Adolescents with a Chronic Physical Health Condition A physical chronic condition comes with many challenges and negatively impacts the healthrelated quality of life (HRQOL) of those affected. Self-regulation plays an important role in successfully coping with the demands of a chronic condition. In line with a resource-oriented approach, this study aimed to investigate themoderating effect of self-regulation on the relationship between disease severity andHRQOL. For this, 498 adolescents with cystic fibrosis, juvenile idiopathic arthritis, or type-1 diabetes aged of 12-21 years (M= 15.43, SD= 2.07) were recruited through three patient registers. Subjective disease severity, self-regulation (Brief Self-Control- Scale), andHRQOL (DISABKIDSChronicGenericMeasure)were examined at two time points (T1 and T2, one year apart). Cross-sectional analysis showed significant effects of subjective disease severity and self-regulation on HRQOL. Prospective analysis, in which HRQOL at T1 was controlled for, revealed that disease severity only predicted emotion-related HRQOL at T2; selfregulation emerged as a predictor for HRQOL subscales independence, emotion, inclusion, exclusion, and treatment. A significantmoderation effect of self-regulation was found on the relationship between disease severity and HRQOL emotion. Our results highlight the positive impact of self-regulation on quality of life, specifically in the context of chronic conditions and represent a starting point for prevention and intervention approaches.
RESUMO
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 (Mage = 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 (ß > 0.684) and BMI (ß > 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 (ß = 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.
