There seems to be a consensus that family influences on dietary habits are important. However, no data relative to breakfast have been published yet.
To investigate whether and how breakfast energy intake aggregates within French families.
A total of 398 families of the Stanislas Family Study who filled in a 3 day food consumption diary were selected. Absolute and relative breakfast energy intakes (BEI in kcal/day and RBEI in percentage of daily intake, respectively) were both studied.
By using a variance component analysis, no genetic influence was shown in family aggregation of both BEI and RBEI. Intra-generation common environmental contribution to total phenotypic variance of BEI and RBEI was higher than inter-generation; both were increased with frequency of sharing breakfast. Furthermore frequency of sharing breakfast contributed to increase family resemblance in breakfast energy intake, particularly in offspring for BEI and RBEI, and in spouses for RBEI. Smoking habits, alcohol consumption, BMI or physical activity were related to family resemblance, but after adjustment on each factor degrees of resemblance were almost unchanged.
General findings of this study were that family aggregation in breakfast absolute and relative energy intakes was significant within Stanislas families. Family resemblance depended on inter- and intra-generation components and was modified by the number of shared breakfasts. Our study confirmed that familial habits act on family resemblance in both absolute and relative breakfast energy intakes, so that family should be a favorite unit for health and diet promotion programs.

人们似乎已达成共识，即家庭对饮食习惯有重要影响。然而，尚未有关于早餐的相关数据发表。
调查法国家庭中早餐能量摄入是否存在聚集现象以及如何聚集。
选取了斯坦尼斯拉斯家庭研究中的398个家庭，这些家庭填写了一份3天的食物消费日记。同时研究了早餐能量的绝对摄入量（以千卡/天为单位的BEI）和相对摄入量（占每日摄入量百分比的RBEI）。
通过方差成分分析，未发现BEI和RBEI的家庭聚集存在遗传影响。代内共同环境对BEI和RBEI总表型方差的贡献高于代际；两者均随共享早餐频率的增加而增加。此外，共享早餐的频率有助于增加早餐能量摄入的家庭相似性，特别是在BEI和RBEI方面的后代以及RBEI方面的配偶中。吸烟习惯、饮酒、BMI或身体活动与家庭相似性有关，但在对每个因素进行调整后，相似程度几乎不变。
本研究的总体发现是，斯坦尼斯拉斯家庭中早餐绝对和相对能量摄入的家庭聚集现象显著。家庭相似性取决于代际和代内成分，并因共享早餐的次数而改变。我们的研究证实，家庭习惯对早餐绝对和相对能量摄入的家庭相似性均有影响，因此家庭应成为健康和饮食促进项目的理想单位。
