Objective

To assess whether in very preterm infants (1) body mass index (BMI) Z-score and weight-for-length (WtFL) Z-score at 1 year of age and (2) head growth from discharge to 1 year are associated with breastfeeding at discharge and the age of onset and type of complementary foods.

Study design

Observational cohort study.

Results

Infants started on only ready-made complementary (RMC) feedings at ≤26 weeks adjusted age had the highest adjusted BMI Z-score and WtFL Z-score at 1 year of age. Adjusted change in fronto-occipital circumference was highest in infants either discharged on breastmilk or receiving home-made complementary food with/without RMC (HMM) at ≤26 weeks adjusted age.

Conclusions

Infants started on RMC ≤26 weeks adjusted age had the highest BMI Z-score and WtFL Z-score at 1 year. Head growth from discharge to 1 year was highest in infants either discharged on breastmilk or receiving HMM at ≤26 weeks adjusted age.

早产儿开始年龄和辅食类型与体重指数和 12 个月时身长别体重的关联。

客观的

评估极早产儿 (1) 1岁时的体重指数 (BMI) Z分数和身长别体重 (WtFL) Z分数和 (2) 从出院到 1 岁的头部生长是否与出院时的母乳喂养、发病年龄和辅食类型。

学习规划

观察性队列研究。

结果

在 ≤ 26 周调整年龄开始仅使用现成补充 (RMC) 喂养的婴儿在 1 岁时调整后的 BMI Z分数和 WtFL Z分数最高。在 ≤ 26 周调整年龄时，无论是母乳喂养还是接受自制辅食，含/不含 RMC (HMM) 的婴儿，额枕围的调整后变化最高。

结论

开始 RMC ≤ 26 周调整年龄的婴儿在 1岁时的 BMI Z分数和 WtFL Z分数最高。从出院到 1 岁的头部生长在母乳出院或接受 HMM 调整年龄≤26 周的婴儿中最高。
