The aim of the current study was to examine and compare dieting and unhealthy weight-control behaviours (UWCB) in population-based samples in two large urban areas in Spain (Barcelona) and in the USA (Twin Cities of Minneapolis and St. Paul, Minnesota). Additionally, use of UWCB across weight categories was explored in both samples. Participants included 1501 adolescents from Barcelona (48% girls, 52% boys) and 2793 adolescents from the Twin Cities (53% girls, 47% boys). The main outcome measures were dieting, UWCB (less extreme and extreme) and weight status. Although dieting and UWCB were prevalent in both samples, particularly among girls, the prevalence was higher in the US sample. In both countries, the report of dieting and use of UWCB was highest among overweight and obese youth. Prevention interventions that address the broad spectrum of eating and weight-related problems should be warranted in light of the high prevalence and co-occurrence of overweight and unhealthy weight-related behaviours.
本研究旨在考察和比较两个大型城市地区(西班牙巴塞罗那和美国明尼苏达州双子城的明尼阿波利斯和圣保罗)基于人群的样本中的节食和不健康的体重控制行为(UWCB)。此外,还探讨了这两个样本中体重类别之间 UWCB 的使用情况。参与者包括来自巴塞罗那的 1501 名青少年(48%为女孩,52%为男孩)和来自双子城的 2793 名青少年(53%为女孩,47%为男孩)。主要结局指标为节食、UWCB(较轻和较重)和体重状况。尽管节食和 UWCB 在两个样本中都很普遍,尤其是在女孩中,但在美国样本中更为普遍。在这两个国家,报告的节食和 UWCB 的使用在超重和肥胖青少年中最高。鉴于超重和不健康的体重相关行为的高流行率和同时发生,应该保证采取预防干预措施来解决广泛的饮食和体重相关问题。
