食物新恐惧症（即回避新食物的倾向）的遗传性在 4 至 7 岁的双胞胎中进行了测试。我们还研究了食物恐惧症是否与亲子喂养关系或儿童体脂肪有关。我们研究了 66 对同性双胞胎，其中包括 37 对同卵双胞胎 (MZ) 和 29 对双卵双胞胎 (DZ)。通过家长问卷（儿童食物恐吓量表，CFNS）评估食物恐新症，以及儿童喂养方式和“责任分工”喂养关系。直接测量儿童人体测量和体脂百分比。 MZ 和 DZ 双胞胎对食物恐惧症的相关性分别为 r=0.71 和 r= -0.01；遗传力= 72%。更大的食物恐惧症与儿童对提示食物的饮食依从性降低有关（p < 0.001），对最初拒绝的食物的饮食依从性降低（p < 0.001），并且 - 仅在女孩中 - 父母的食物需求较少（p = 0.01）。有趣的是，母亲 BMI 和儿童 BMI z 分数之间的相关性仅在食物恐新症高（p=0.03）的儿童中显着，而不是低（p=0.55）。儿童食物恐惧症是一种高度遗传的特征，以前与情绪有关，与不太顺从的亲子喂养关系有关。对抗食物新恐惧症和促进更和谐的喂养关系的策略可能在预防肥胖方面发挥作用。
The heritability of food neophobia, the tendency to avoid new foods, was tested in 4- to 7-year-old twins. We also examined whether food neophobia is associated with parent-child feeding relations or child body fat. We studied sixty-six same-sex twin pairs, including 37 monozygotic (MZ) and 29 dizygotic (DZ) pairs. Food neophobia was assessed by parent questionnaire (Child Food Neophobia Scale, CFNS), as were child feeding practices and “division of responsibility” feeding relations. Child anthropometry and percent body fat were directly measured. MZ and DZ twin pair correlations for food neophobia were r=0.71 and r= −0.01, respectively; heritability= 72%. Greater food neophobia was associated with reduced child eating compliance of prompted foods (p< 0.001) reduced eating compliance of initially refused foods (p< 0.001), and – among girls only – fewer parental food demands (p= 0.01). Interestingly, the correlation between maternal BMI and child BMI z-score was significant only for children high (p=0.03), but not low (p=0.55), in food neophobia. Child food neophobia, a highly heritable trait previously linked to emotionality, was associated with less compliant parent-child feeding relations. Strategies to combat food neophobia and foster more harmonious feeding relationships may have a role in obesity prevention.
