To investigate the impact of eating behaviour traits on central obesity, prediabetes and associated major dietary food patterns.
Assessment of eating behaviour was based on the revised German version of the Three-Eating Factor Questionnaire using cross-sectional and longitudinal data of a feasibility study in employees. Data on lifestyle and nutrition were obtained by validated self-administered questionnaires. Baseline characteristics were analysed by the univariate χ2 test or the Mann-Whitney test. To quantify correlations linear regression analysis was used.
The Delay of Impaired Glucose Tolerance by a Healthy Lifestyle Trial (DELIGHT), which investigated measures to prevent type 2 diabetes mellitus in 2004-2008.
Employees (21-64 years, 127 men, 157 women) with elevated waist circumference (men ≥ 94 cm, women ≥ 80 cm) of five medium-sized companies in northern Germany.
At baseline (T0), BMI but particularly waist circumference showed a strong inverse correlation with flexible control (P < 0.0001) and a positive correlation with disinhibition (P < 0.0001) and rigid control (P = 0.063). Flexible control was also significantly inversely related to fasting plasma glucose (P = 0.040), energy intake (P < 0.0001), intake of meat and meat products (P = 0.0001), and positively associated with intake of fruit and vegetables (P < 0.0001) at baseline (T0). Changes in flexible control within the first year of intervention (T1 v. T0) predicted changes in central obesity (P < 0.0001) and fasting plasma glucose (P = 0.025).
DELIGHT shows that flexible control characterizes individuals with a higher dietary quality, a lower waist circumference and a lower glucose level. Enhancing flexible control more than rigid control, and decreasing disinhibition, seems beneficial in terms of central adiposity and glucose levels.
研究饮食行为特征对中心性肥胖、糖尿病前期及相关主要膳食食物模式的影响。
采用修订后的德国版三因素饮食问卷评估饮食行为，使用横断面和员工可行性研究的纵向数据。通过验证后的自我管理问卷获取生活方式和营养数据。采用单变量 χ2 检验或 Mann-Whitney 检验分析基线特征。采用线性回归分析量化相关性。
德国预防 2 型糖尿病的健康生活方式延迟糖耐量受损试验（DELIGHT），该试验于 2004-2008 年调查了预防 2 型糖尿病的措施。
德国北部五家中型公司腰围升高（男性≥94cm，女性≥80cm）的 21-64 岁员工（男性 127 人，女性 157 人）。
在基线（T0）时，BMI 但尤其是腰围与灵活控制呈强负相关（P＜0.0001），与抑制失控（P＜0.0001）和刚性控制（P＝0.063）呈正相关。灵活控制也与空腹血糖（P＝0.040）、能量摄入（P＜0.0001）、肉类和肉类产品摄入（P＝0.0001）呈显著负相关，与水果和蔬菜摄入呈正相关（P＜0.0001）。在干预的第一年（T1 与 T0）内，灵活控制的变化预测了中心性肥胖（P＜0.0001）和空腹血糖（P＝0.025）的变化。
DELIGHT 表明，灵活控制的特点是饮食质量更高、腰围更小、血糖水平更低。与刚性控制相比，增强灵活控制、减少抑制失控，在中心性肥胖和血糖水平方面似乎更有益。
