Do 6-y changes in eating behaviors predict changes in body weight? Results from the Québec Family Study

Abstract

OBJECTIVE: This study was performed to examine changes in eating behaviors as assessed by the three-factor eating questionnaire (TFEQ) and to quantify the potential associations between these eating behaviors and body weight changes in a 6-follow-up study. DESIGN AND SUBJECTS: Prospective study performed in men and women who were tested twice (Visit 1 ¼ 1989-1995 and Visit 2 ¼ 6 y later) in the Québec Family Study (QFS). RESULTS: Women were more restrained and less hungry than men. To reduce food intake, women relied more on strategic dieting behavior and avoided more fattening food. However, they had higher emotional and situational susceptibility to eat than men. Significant decreases in the disinhibition score were noted over time in women (Po0.01), which resulted from a decrease in habitual susceptibility behavior to increase food intake. In men, we observed an increase in the avoidance of fattening food (Po0.05). In both genders, we found that the 6-y change in restraint behavior was negatively correlated with body weight changes (Po0.05). In women, a high restraint behavior seems to promote weight gain, whereas in men, it is associated with the opposite trend. CONCLUSION: These results suggest that variables reflecting some eating behaviors are associated with body weight changes in a free-living context. However, these behaviors are expressed differently between men and women. These behaviors should be considered in clinical interventions for individuals seeking a better body weight control.

Interaction between Disinhibition and restraint: Implications for body weight and eating disturbance

“…Of the 426 participants who provided personal details, 75 were male and 351 female however, only females were included in the analysis. This was due to evidence suggesting that levels of TFEQ factors differ between males and females (22)(23)(24). In addition, females are known to have a higher susceptibility to disturbed eating behavior compared to males (25).…”

How dieting makes some fatter: from a perspective of human body composition autoregulation

“…In the decade that followed, however, more than a dozen prospective studies (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24) , conducted over periods ranging from 1 to 15 years, have suggested that dieting to lose weight is associated with future weight gain and obesity, with many of them showing this association even after adjustment for potential confounders such as baseline BMI, age and several lifestyle and behavioural characteristics. Particularly informative are the 3-year follow-up studies of Stice et al (15) showing that adolescents with baseline dieting had three times the risk of onset of obesity than the non-dieters, and the 6-15-year follow-up study of Korkelia et al (16) reporting that initially normal-weight subjects who were attempting to lose weight had two times the risk of major weight gain (> 10 kg) than non-dieters.…”

The Eating Inventory, body adiposity and prevalence of diseases in a quota sample of Czech adults

“…[7][8][9][10][11][12][13][14][15] Previous studies postulated that dietary restraint was associated with eating disorders 9,10 and stress-induced eating, 11 but also with lower body weight [16][17][18] and success in dieting and maintenance of weight loss. [12][13][14][15][19][20][21] According to Westenhoefer et al, 15 'flexible control' exerted in dietary restraint represents a predictor of good weight management. A drop in the disinhibition score appeared the only significant factor influencing the body mass index (BMI) decrease in response to 1-year treatment with sibutramine.…”
