Objective: The aim of this study was to explore the prevalence of and differences in self-reported occasions of overeating (such as at celebrations and other parties), compensatory behaviours and specific weight gain prevention strategies among young Dutch adults according to sociodemographics and overweight status. Design and subjects: Cross-sectional data were analysed from Dutch adults aged 20-40 years, recruited from an Internet research panel (n ¼ 857, response rate ¼ 76.6%). Using electronic questionnaires, self-report data were collected on sociodemographics, body mass index (BMI), occasions of overeating, compensatory behaviours, and diet and physical activity used as weight gain prevention strategies. Associations were tested using multiple linear and logistic regression analyses. Results: Of the participants, 48.6% reported occasions of overeating at least once a week during the 4-week period, 44.6% reported compensating for these occasions and 72.9% reported engaging in dietary and physical activities specifically for weight gain prevention purposes. Only 32.1% of the respondents reported using the recommended combination of diet and physical activity as a weight gain prevention strategy. In addition, results showed that overweight people (BMI $25 kg m -2 ) and women were more likely to report overeating than people with healthy body weights (odds ratio (OR) ¼ 1.79; 95% confidence interval (CI) 1.32 -2.42) and men (OR ¼ 1.50; 95% CI 1.14 -1.97). Overweight people, women and people who regularly reported overeating were also significantly more likely to report compensatory behaviours by eating less and to report specific weight gain prevention strategies using diet and physical activity. Conclusion: The present study suggests that people experience frequent occasions of overeating and try to compensate for such occasions in different ways. However, the combination of dietary changes and physical activity recommended by experts was seldom reported.

Weight gain prevention strategies Overeating Compensatory behavioursBoth diet and physical activity are important for effective weight maintenance 1 . Although earlier studies have shown that high percentages of people are engaged in weight gain preventive action 2 , the rising prevalence of overweight and obesity shows that these are not always effective. This might be explained by the fact that the duration of engagement in weight control behaviours is often very brief and therefore not sufficient to prevent weight change over time, as suggested by a prospective cohort study on the prevalence and duration of specific weight loss strategies 3 . Another explanation might be that people are engaged in non-effective weight gain prevention behaviours. To date, little is known about which dietary and physical activity behaviours people apply to prevent weight gain, since most existing work has focused on weight loss or because more detailed information about such behaviours was not obtained 4 -7 . Exercise and caloric restriction are the two rel...
