Despite significant health risks associated with high body weight and poor diet, little is known about the prevalence and targets of weight-loss and dietary intentions. This information could, however, help tailor behaviour change interventions. Therefore, the present study described weight-loss and dietary intentions and their co-occurrence in a representative sample (N = 1,510; 50.40% women; M = 48.55, SD = 16.68; M = 26.89, SD = 5.92) from Germany (n = 1,006) and Austria (n = 504). Weight-loss (57%) and dietary avoidance intentions (i.e., intention to eat less of certain foods; 59%) were more prevalent than dietary approach intentions (i.e., intention to eat more of certain foods; 34%). A discrepancy between weight-loss intention and indication (i.e., meeting BMI criteria for weight-loss recommendation: BMI ≥ 25) was found for 27% of individuals. Most common target foods were 'snacks high in sugar, fat, and/or salt' (24%), 'meat' (12%) and 'sugar/foods high in sugar' (11%) for avoidance and 'fruits and vegetables' (27%) and 'protein/foods high in protein' (3%) for approach intentions. These findings indicate that individuals might benefit from enhanced awareness of body weight recommendations and a less avoidance-centered perspective on eating, as approach strategies might be more effective in changing behaviour.
尽管高体重和不良饮食会带来重大健康风险,但对于减肥和饮食意图的患病率及目标却知之甚少。然而,这些信息有助于定制行为改变干预措施。因此,本研究描述了来自德国(n = 1,006)和奥地利(n = 504)的一个代表性样本(N = 1,510;50.40%为女性;M = 48.55,SD = 16.68;M = 26.89,SD = 5.92)中的减肥和饮食意图及其同时出现的情况。减肥意图(57%)和饮食回避意图(即少吃某些食物的意图;59%)比饮食促进意图(即多吃某些食物的意图;34%)更为普遍。在27%的个体中发现了减肥意图与指征之间的差异(即符合减肥推荐的BMI标准:BMI≥25)。对于回避意图,最常见的目标食物是“高糖、高脂肪和/或高盐零食”(24%)、“肉类”(12%)和“糖/高糖食物”(11%);对于促进意图,是“水果和蔬菜”(27%)和“蛋白质/高蛋白食物”(3%)。这些发现表明,由于促进策略在改变行为方面可能更有效,个体可能会从提高对体重建议的认识以及减少以回避为中心的饮食观念中受益。
