To develop an index that assesses the degree of adherence to existing diet-lifestyle recommendations for preschoolers (Preschoolers Diet-Lifestyle Index (PDL-Index)) and to investigate its association with obesity.
The PDL-Index was constructed using eleven components (i.e. questions regarding the frequency of consumption of selected foods/food groups, time spent on television watching and on moderate-to-vigorous physical activities).
Scores from 0 to 4 were assigned to all components of the index. The PDL-Index total score ranged from 0 to 44. Higher values of the PDL-Index indicate greater adherence to dietary and lifestyle recommendations for preschoolers or otherwise greater adherence to healthier dietary-lifestyle patterns.
As a validation procedure, a sample of 2287 preschoolers from Greece (GENESIS study) was used.
The participants following healthier diet-lifestyle patterns (third tertile of PDL-Index) were less likely to be obese or overweight/obese compared to those following unhealthy diet-lifestyle patterns (first tertile of PDL-Index). It was observed that a 1/44 unit increase in the score of the PDL-Index was associated with approximately 5 % and 3 % lower odds of being obese and overweight/obese, respectively. Statistically significant results were observed after adjusting for potential confounders.
The suggested PDL-Index could help public health policy makers in identifying vulnerable population subgroups and developing cost-effective, targeted intervention actions both in family and preschool settings. In addition, health-care professionals can use the PDL-Index to evaluate diet quality, lifestyle and risk for overweight/obesity at an individual level and counsel parents accordingly.
制定一个评估学龄前儿童现有饮食生活方式建议依从程度的指数（学龄前儿童饮食生活方式指数（PDL-Index）），并探讨其与肥胖的关系。
PDL-Index 由十一个部分组成（即选择食物/食物组的消费频率、看电视时间和中高强度体育活动时间的问题）。
为该指数的所有部分分配 0 到 4 的分数。PDL-Index 总分范围为 0 到 44。PDL-Index 值越高，表明对学龄前儿童饮食和生活方式建议的依从性越高，或者对更健康的饮食生活方式模式的依从性越高。
作为验证程序，使用了来自希腊的 2287 名学龄前儿童（GENESIS 研究）的样本。
遵循更健康饮食生活方式模式（PDL-Index 第三 tertile）的参与者肥胖或超重/肥胖的可能性低于遵循不健康饮食生活方式模式（PDL-Index 第一 tertile）的参与者。观察到 PDL-Index 得分每增加 1/44 单位，肥胖和超重/肥胖的几率分别降低约 5%和 3%。在调整了潜在混杂因素后，观察到了统计学上显著的结果。
该建议的 PDL-Index 可以帮助公共卫生政策制定者识别脆弱人群亚组，并在家庭和学龄前环境中制定具有成本效益的、有针对性的干预措施。此外，医疗保健专业人员可以使用 PDL-Index 来评估个体的饮食质量、生活方式和超重/肥胖风险，并相应地为家长提供建议。
