Suboptimal vegetable and fruit consumption by young children is common. Identifying predictors of vegetable and fruit intakes is important for informing strategies to promote sufficient intakes of these foods from early life. The aim of the present study was to examine predictors of toddlers' vegetable and fruit intakes at age 18 months. This study involved secondary analysis of data from 361 child-mother dyads participating in the Melbourne Infant Feeding, Activity and Nutrition Trial in 2008-2010 at child ages four, nine and 18 months. Children's vegetable and fruit intakes were assessed at age 18 months using multiple 24-h dietary recalls. Data on potential predictor measures were collected via parent-completed questionnaires when children were four or nine months of age. Bivariate and multivariable linear regression models were used to test associations between children's average daily vegetable or fruit intake and potential predictors controlling for treatment arm and clustering by parent group. Multivariable models also controlled for covariates and potential confounders. Home availability of vegetables at age nine months was found to predict children's vegetable intake at age 18 months and remained significant (β = 20.19, 95% CI:7.23, 33.15, p = 0.003) in the multivariable model. Children's average daily fruit intake at age 18 months was predicted by maternal education at child age four months and the availability of fruits in their home at child age nine months. Maternal education remained significant (β = 30.83, 95% CI:12.17, 49.48, p = 0.002) in the multivariable model. Strategies to promote adequate vegetable and fruit intakes among young children should address known barriers to the availability of vegetables and fruits in the home from early in life. Additionally, messages encouraging fruit consumption may need to be tailored to mothers with lower levels of education.
幼儿蔬菜和水果摄入不足的情况很常见。确定蔬菜和水果摄入量的预测因素对于制定策略以促进这些食物从生命早期开始充足摄入非常重要。本研究旨在研究 18 个月大的幼儿蔬菜和水果摄入量的预测因素。本研究对 2008-2010 年墨尔本婴幼儿喂养、活动和营养试验中 361 名母婴对参与的研究数据进行了二次分析,该试验中儿童年龄分别为 4、9 和 18 个月。在 18 个月时,使用多次 24 小时膳食回忆法评估儿童的蔬菜和水果摄入量。当儿童 4 或 9 个月大时,通过父母完成的问卷收集潜在预测措施的数据。使用单变量和多变量线性回归模型来检验儿童平均每日蔬菜或水果摄入量与潜在预测因素之间的关联,同时控制治疗组和父母组的聚类。多变量模型还控制了协变量和潜在混杂因素。九个月时家庭中蔬菜的供应情况被发现可以预测 18 个月时儿童的蔬菜摄入量,且在多变量模型中仍然具有统计学意义(β=20.19,95%CI:7.23,33.15,p=0.003)。18 个月时儿童的平均每日水果摄入量与儿童四个月时母亲的教育程度以及九个月时家中水果的供应情况有关。母亲的教育程度在多变量模型中仍然具有统计学意义(β=30.83,95%CI:12.17,49.48,p=0.002)。促进幼儿摄入足够蔬菜和水果的策略应该从生命早期开始解决家庭中蔬菜和水果供应的已知障碍。此外,鼓励水果消费的信息可能需要针对教育程度较低的母亲进行调整。
