Studies on children’s nutritional behaviour (CNB) rarely compare children’s answers regarding the frequency of their sugar intake with the respective statements of their parents. Therefore, data from a prevention study were used to analyse this aspect, as well as a potential correlation between Marburg Sugar Index (MSI) values and caries experience of children. The present study based its questionnaire data on CNB and caries data. Pairs of questionnaires filled in separately by children and parents of the participating families were dichotomised by either having completed the diet section entirely (Group A) or in part (Group B). The MSI scores were calculated separately for children and parents. The statistical confidence level was set at α = 0.05 (two-sided). Furthermore, the Pearson correlation coefficient was calculated and tested for “r = 0”. Additionally, a test for equality of the correlations was applied. The number of available questionnaire pairs was 429 in Group A and 400 in Group B. In both groups, significant correlations between children’s and parents’ MSI scores (A: r = 0.301, p < 0.001; B: r = 0.226, p < 0.001) were found. Using Spearman’s Rho, a significant correlation between MSI scores and children’s caries experiences was observed in Group A. MSI scores based on dietary questionnaires can be used to obtain consistent information on children’s CNB provided by the children themselves or their parents. This is true even when the MSI score has to be calculated on the basis of incomplete questionnaires. Questionnaire-based CNB information can improve the effectiveness of individual or group preventive measures supplemented by individually adapted nutritional counselling.
关于儿童营养行为（CNB）的研究很少将儿童关于糖摄入量的频率的回答与父母的相关陈述进行比较。因此，利用预防研究的数据来分析这一方面，以及 Marburg 糖指数（MSI）值与儿童龋齿经历之间的潜在相关性。本研究基于 CNB 和龋齿数据的问卷数据。通过将由参与家庭的儿童和父母分别填写的问卷进行二分法，将其分为完全完成饮食部分的（A 组）和部分完成的（B 组）。分别为儿童和父母计算 MSI 分数。统计置信水平设置为 α = 0.05（双侧）。此外，还计算并测试了 Pearson 相关系数为“r = 0”。此外，还应用了相关性相等的检验。在 A 组中，可用的问卷对数量为 429 对，在 B 组中为 400 对。在两组中，均发现儿童和父母的 MSI 分数之间存在显著相关性（A：r = 0.301，p < 0.001；B：r = 0.226，p < 0.001）。使用 Spearman's Rho，在 A 组中观察到 MSI 分数与儿童龋齿经历之间存在显著相关性。基于饮食问卷的 MSI 分数可以用于从儿童自身或其父母那里获得有关儿童 CNB 的一致信息。即使 MSI 分数必须基于不完整的问卷进行计算，这也是如此。基于问卷的 CNB 信息可以提高个人或团体预防措施的有效性，补充个别适应的营养咨询。
