Objectives: The purpose of this study was to identify lifestyle patterns that are characteristic of overweight and obese European adults in the context of educational level.
Methods: This was a cross-sectional study of dietary data from 1235 men and 10 343 women. Dietary intake, educational level, and physical activity were assessed using questionnaires. A principal component analysis was used to derive lifestyle patterns, and associations with being overweight or obese (OW/OB) and waist circumference (WC) were explored by applying a multivariate logistic regression.
Results: Overall, 35% of women and 68% of men were OW/OB, of whom 30% and 40%, respectively, had ≤12 y of education. The principal component analysis derived 2 distinct dietary patterns (healthy vs. unhealthy). The daily intake of fruits (fresh, canned, and juice) and vegetables was found to be associated with lower odds of being OW/OB and WC in women only. In contrast, the daily intake of diet soft drinks was associated with higher odds of being OW/OB in women and men, but the daily intake of sweets was associated with higher odds of WC in women only. In both sexes, having >12 y of education was inversely associated with being OW/OB. No associations were observed for regular soft-drink intake.
Conclusions: A healthy dietary pattern constituting of a daily intake of fruits and vegetables was inversely associated with being OW/OB in women. Conversely, a diet soft-drink intake was positively associated with being OW/OB in both sexes, probably because of a reduction in overall energy intake. More studies are recommended to clarify the effectiveness of diet soft-drink consumption in controlling caloric intake and as a healthier alternative to regular soft drinks and sweets.
