Methods: Latent growth curve analysis was used to examine whether growth parameters of zBMI could be predicted by depressive symptoms (n ¼ 2,051 adolescents, 48.5% female, at baseline; 1,465 with data at all three time points). Specifically, we tested whether depressive symptoms were associated with the initial assessment of BMI (intercept) as well as with changes in BMI over time (slope). Analyses were performed for the total group, and separately for boys and girls. Results: Depressive symptoms were not associated with the slope of zBMI. In girls, but not boys, depressive symptoms were positively associated with the intercept of zBMI. Conclusions: Findings suggest that although depressive symptoms among females are associated with a higher zBMI, they do not predict excessive weight gain during early-to-mid adolescence.

Design and participants: An experimental design with a three (confederate’s M&M intake: high, low, none) by two (confederate's weight status: slim, normal weight) factorial design. A total of 102 normal-weight women aged 18 to 30 were exposed to a same-sex confederate and were observed in a living-room setting. Measurements: Food intake was observed during a 15-min break between two tasks. Findings: A significant interaction effect was found between the intake and weight manipulation of the confederate, showing that the modeling effect was only found in the normal-weight appearance condition. Conclusion: Normal-weight young women are more inclined to imitate the food intake of a female confederate when they ar...

A longitudinal study with 3 study waves (1-year intervals) involving 1248 Dutch adolescents (49% girls; mean age = 13.7 years) at schools providing different educational levels was used to determine adolescents who moved and did not move to a lower educational level in the first year, or in the second year, and to examine whether this movement could be predicted by BMI z-scores (zBMI), after controlling for a large range of potential confounding factors. A total of 1164 Dutch adolescents continued in the same level of education, whereas 84 adolescents moved to a lower educational level (43 moved in the first and 41 in the second year). A higher zBMI significantly increased the risk of a general transition to a lower educational level, and...

Participants were 157 patients (144 females, 13 males) who completed questionnaires approximately 34 months (range = 8-68 months) after laparoscopic adjustable gastric banding (LAGB). Our data showed a well-fitting model in which external and emotional eating were associated with outcome through binge eating. Several exercise beliefs were associated with physical exercise, but physical exercise was not associated with weight loss or physical health. Binge eating was related more strongly to the outcome after gastric banding than physical exercise. Future research should examine whether a strong focus on the management of binge eating and external and emotional eating could improve the outcome of morbidly obese patients with unsuccessful weight outcome after obesity surgery.

No study, however, has tested the potential influences of both types of situational norms on intake during the same eating occasion. We experimentally tested the effects of manipulating portion size and the intake of others on young women's meal intake during a 20 min eating opportunity. An experimental design with a three (confederate's intake: small, standard, large) by two (portion size: small, standard) between-participants design was used. A total of eighty-five young women participated. Portion size and the confederate's intake both influenced young women's intake. Participants consumed more when offered a larger portion than when offered a smaller portion, and they also ate more when their eating companion ate more. The present results indicate that the effects of portion size and the intake of others were independent but additive. Thus, both types of situational norms might independently guide an individual's intake during a single eating occasion.

Our aim was to examine the association between weight loss and self-regulation cognitions before and after laparoscopic adjustable gastric banding for morbid obesity or severe obesity with serious comorbidity. Six months before and 1 year after the operation, the Obesity Cognition Questionnaire and an eating behavior self-efficacy scale were completed by 77 patients: 68 women, 9 men, mean age 43 years (range, 27-62 y), mean preoperative body mass index 47 kg/m(2) (range, 36-63 kg/m(2)). Pearson correlations were calculated and t tests and effect size calculations were used to examine preoperative to postoperative changes of self-regulation cognitions. The mean body mass index 1 year after the operation was 38 kg/m(2) (range, 25-55 kg/m(2)). Self-regulation cognitions did not predict weight outcome, but the self-regulation cognitions time-line (ie, the attitude about the prognosis of one's overweight, P < .001), psychologic consequences (P = .002), and self-efficacy (P < .001) changed in a positive way 1 year after the operation. Intake screening of self-regulation cognitions is of little use for prediction of short-term weight outcome after bariatric operation. It is suggested that beliefs about one's capability to control eating behavior change after the operation.
