To investigate temporal changes in the prevalence of disordered eating behaviors among adolescents, and their association with socio demographic factors and overweight. Using probability sampling, two population-based cross-sectional surveys were conducted: one in 2005 (n=511) and the other in 2010 (n=314). The frequency of disordered eating behaviors (binge eating, strict dieting or fasting and compensatory behaviors) was investigated using a self-administered questionnaire. The presence of binge eating increased by 18.4% in the 5 years between the two surveys. In 2005, girls were 1.95 times more likely to engage in strict dieting or fasting than boys, and this difference increased to 7.02 times in 2010. Overweight adolescents were 2.29 times more likely to undertake strict dieting than non-overweight adolescents in 2005 and 3.65 times more likely to do so in 2010. No significant associations were found for compensatory behaviors. A pronounced increase in the prevalence of binge eating was observed, and girls and overweight adolescents were more likely to engage in strict dieting or fasting.
为了调查青少年饮食失调行为的流行率随时间的变化，以及它们与社会人口因素和超重的关系。使用概率抽样，进行了两次基于人群的横断面调查：一次在 2005 年（n=511），另一次在 2010 年（n=314）。使用自我管理问卷调查了饮食失调行为（暴食、严格节食或禁食和补偿行为）的频率。在两次调查之间的 5 年中，暴食的发生率增加了 18.4%。2005 年，女孩暴食的可能性是男孩的 1.95 倍，而这一差异在 2010 年增加到 7.02 倍。超重青少年在 2005 年进行严格节食的可能性是非超重青少年的 2.29 倍，在 2010 年则为 3.65 倍。补偿行为没有显著关联。观察到暴食的流行率显著增加，而女孩和超重青少年更有可能进行严格节食或禁食。
