Formation Mechanisms, Interrelationships, and Effects of Cognitive Factors on Diet and Physical Activity During the Post-Bariatric Surgery Period: A Cross-Sectional Study Based on Compensatory Carry-Over Action Model.

Background: Diet and physical activity (PA) are pivotal behaviors for managing energy balance post-bariatric surgery. Given the need for dual behavioral management, understanding the interplay of cognitive factors influencing these behaviors is crucial. This study applied the compensatory carry-over action model (CCAM) to explore the impact of cognitive factors on behaviors and their subsequent effects on subjective health outcomes. Methods: This cross-sectional study was conducted among patients at the third month after bariatric surgery in China. Data on diet and PA status, behavioral cognitive factors (intention, self-efficacy, compensatory belief, transfer cognition), and subjective health outcomes (perceived stress, well-being, quality of life) were collected. Structural equation model (SEM) was employed to test hypotheses in CCAM and assess mediation relationships. Results: Analysis of data from 239 patients revealed the following: (1) Among antecedent cognitive factors, only compensatory belief significantly influenced diet (P<0.001). (2) Intention and self-efficacy directly correlated with their respective behaviors, while compensatory belief affected intention, and transfer cognition impacted self-efficacy (P<0.05), aligning with CCAM hypotheses. (3) PA demonstrated significant influence only on perceived stress (P=0.004), whereas diet significantly affected all subjective health outcomes (P<0.05). (4) Mediation analysis indicated intention partially mediated the relationship between compensatory belief and diet and fully mediated the relationship between compensatory belief and PA. Self-efficacy completely mediated the relationship between transfer cognition and diet and PA. Conclusion: Transfer cognition's carry-over effect did not directly influence behaviors among antecedent cognitions. Interventions should primarily target improving diet by mitigating compensatory belief. Moreover, diet exhibited a more pronounced impact on overall health compared to PA. Consequently, prioritizing dietary intervention over PA intervention is warranted based on the analysis of CCAM and the aim of promoting joint behaviors post-bariatric surgery.

Individual, family and social-related factors of eating behavior among Chinese children with overweight or obesity from the perspective of family system.

Purpose: The purpose of the present study is to examine the factors contributing to the development of eating behavior in overweight and obese children from the perspective of the family system. Methods: A cross-sectional survey was conducted by using convenience sampling method to select 388 participants in two primary schools in Jiangsu, China. Individual, family and social-related factors were collected. Individual factors included age, gender, ethnicity, single child, social anxiety, depression, physical activity, sleep duration, screen time. Family factors included family environment, family structure, family function, family income, parenting style, parental feeding behavior, home food environment and marital satisfaction. Social-related factors included place of residence, number of surrounding restaurants and social support. Univariate analysis, correlation analysis and multivariate analysis were used to identify factors of eating behavior among Chinese children with overweight and obese. Results: In this study, 388 participants took part with a 94.865% response rate. In the univariate analysis, the significant differences regarding Dutch Eating Behavior Questionnaire (DEBQ) scores were found between children aged 6-9 years and those aged >9 years. Correlation analysis indicated that parent's nutrition literacy (r = 0.118, P < 0.05), pressure to eat (r = 0.212, P < 0.01), perception of child weight (r = -0.112, P < 0.05) and family function (r = -0.563, P < 0.01) were associated with children's eating behavior. With regard to psychosocial factors, children's social anxiety (r = 0.299, P < 0.01) and depressive symptoms (r = 0.081, P < 0.05) were in positive correlation with eating behavior. The independent variables included in the initial model were age, father's employment status, social anxiety, maternal punishment and harshness, parents' nutrition literacy, pressure to eat, family function and perception of child weight. These variables in the final model accounted for 20.7% of the variance. Conclusion: We found that age, father's employment status, social anxiety, maternal punishment and harshness, parents' nutrition literacy, pressure to eat, family function and perception of child weight have great effect on children's eating behavior who are overweight or obese. As early childhood is a critical timeline for child development, children's social anxiety, parenting style, parent's nutrition literacy, parent's feeding behavior and family function should be intervened to promote eating behavior. Intervention programs aimed at promoting healthy eating behaviors among children, thereby mitigating the risk of pediatric obesity, should primarily target parents.
