    Associations between dietary patterns and obesity phenotypes
    (Springer Nature, 2009-09-08) Paradis, Ann-Marie; Pérusse, Louis; Godin, Gaston; Vohl, Marie-Claude
    Objective: To examine whether dietary patterns are associated with obesity phenotypes. Design: Cross-sectional study. Subjects: We recruited 664 participants aged between 18 and 55 years. Dietary data were collected from a food frequency questionnaire. A factor analysis was performed to derive dietary patterns. Body mass index (BMI), weight and waist girth were recorded using standard procedures. Fat mass and fat-free mass were assessed by electrical bioimpedance. Obesity was defined as having a BMIX30 kg m2 and a positive FHO (FHO þ ) as having at least one obese first-degree relative. Results: Two dietary patterns were identified; Western and Prudent. The Western pattern was mainly characterized by a higher consumption of refined grains, French fries, red meats, condiments, processed meats and regular soft drinks whereas the Prudent pattern was mainly characterized by a higher consumption of non-hydrogenated fat, vegetables, eggs and fish and seafood. Subjects in the top tertile of the Western pattern had higher BMI, weight, waist girth, waist-to-hip ratio and fat mass than those in the lower tertile. In contrast, subjects in the top tertile of the Prudent pattern had lower BMI, weight, waist girth, fat mass, HDL-cholesterol levels, and lower triglyceride levels than those in the lowest tertile. Individuals in the upper tertile of the Western pattern were more likely to be obese (obesity was defined as having a BMIX30 kg m2) (OR ¼ 1.82, 95% CI 1.16–2.87) whereas those in the upper tertile of the Prudent pattern were less likely to be obese (OR ¼ 0.62, 95% CI 0.40–0.96). These latter significant associations were only observed among those with FHO þ . No such association was observed among FHO individuals. Conclusion: Individuals having a high score of Western pattern were more likely to be obese and those having a high score of the Prudent pattern were less likely to be obese, and this is particularly among individuals with an FHO+.

    Eating behaviors of non-obese individuals with and without familial history of obesity
    (Cambridge University Press, 2008-09-10) Paradis, Ann-Marie; Pérusse, Louis; Godin, Gaston; Lemieux, Simone; Vohl, Marie-Claude
    The aim of the present study was to examine whether eating behaviours and their subscales are associated with familial history of obesity (FHO) in a cohort of 326 non-obese men and women. Anthropometric measurements, eating behaviours (Three-Factor Eating Questionnaire) and dietary intakes (FFQ) have been determined in a sample of 197 women and 129 men. A positive FHO (FHO+) was defined as having at least one obese first-degree relative and a negative FHO (FHO-) as no obese first-degree relative. Men with FHO+ had higher scores of cognitive dietary restraint and flexible restraint than men with FHO-. In women, those with FHO+ had a higher score of disinhibition than women with FHO-. In both men and women, eating behaviours were not significantly associated with the number of obese family members. However, having an obese mother was associated with higher scores of cognitive dietary restraint, flexible restraint and rigid restraint in women. These findings demonstrate that eating behaviours of non-obese subjects are different according to the presence or absence of obese family members. More specifically, having an obese mother is associated with a higher dietary restraint score in women.

    Interaction between familial history of obesity and fat intakes on obesity phenotypes
    (Karger, 2009-01-16) Paradis, Ann-Marie; Pérusse, Louis; Godin, Gaston; Vohl, Marie-Claude
    Aim: To evaluate whether familial history of obesity (FHO) interacts with dietary fat intake (DFI) on obesity-related phenotypes. Methods: We recruited 664 participants aged between 18 and 55 years. A positive FHO (FHO+) was defined as having at least 1 obese first-degree relative and a negative FHO (FHO-) as no obese first-degree relative. Dietary intakes were collected from a food-frequency questionnaire. Body mass index, weight and waist girth were recorded using standard procedures. Fat mass and fat-free mass were assessed by electrical bioimpedance. Results: Significant interaction effects (FHO x DFI) were observed for body mass index, weight, waist girth and fat mass (p interaction = 0.05, 0.04, 0.04, 0.02, respectively). Among FHO+ individuals, indices of obesity increased with an increasing amount of DFI, whereas these associations were not observed in FHO- individuals. We also found that FHO+ individuals consuming a high-fat diet were at higher risk of obesity than FHO- individuals consuming a low-fat diet (3.6, CI 2.1-6.2). Conclusion: These results suggest a stronger relationship between DFI and obesity-related phenotypes in individuals with FHO+.

    Prediction of daily fruit and vegetable consumption among overweight and obese individuals
    (ScienceDirect, 2010-02-06) Pérusse, Louis; Godin, Gaston; Bélanger-Gravel, Ariane; Amireault, Steve; Vohl, Marie-Claude; Guillaumie, Laurence
    The purpose of this study is twofold: to identify the determinants of daily fruit and vegetable (F&V) consumption and the moderators of the intention–behaviour relationship. A sample of 225 overweight or obese adults completed a TPB questionnaire. F&V behaviour was assessed at baseline and three months later. Statistical analyses revealed that past behaviour, perceived behavioural control (PBC) and age were significant predictors of daily F&V consumption. In addition, intention was found to interact with anticipated regret. Interventions should encourage the development of habit and PBC. However, the age and level of anticipated regret of the targeted population should be considered when designing interventions.
