BACKGROUND
Growth failure, constituting one the health problems in children below 2 yr of age, can lead to major complications such as death or mental, emotional and physical disabilities. The present study aimed to investigate effective factors on growth failure in the height and weight of less than 2 yr old children of Khorramabad, Iran in 2013.
METHODS
This present longitudinal retrospective study used stratified and clustered sampling. Based on growth curves in family records, the incidence times of growth failure in height and weight of each child were recorded. In the next stage, using recurrent events model (proportional rate model), along with SAS software (version 9.2), the data were modeled.
RESULTS
According to proportional rate model, the effect of mothers' educational level on the rate of growth failure in the height and weight of children was significant (=0.046, =0.049) and the effect of fathers' job was significant only on growth failure in children's weight (<0.001). However, the effect of other variables, including gender, birth order and exclusive breastfeeding status on children's growth failure rate was not significant.
CONCLUSION
Enhancing mother's awareness in low-income families, in tandem with changing educated mothers' attitude towards the required skills and guiding principles for feeding children below 2 yr of age, can be conceived of as the most important approach in dealing with growth failure of children.
背景
生长发育迟缓是2岁以下儿童的健康问题之一，可导致诸如死亡或心理、情感和身体残疾等严重并发症。本研究旨在调查2013年伊朗霍拉马巴德2岁以下儿童身高和体重生长发育迟缓的影响因素。
方法
本纵向回顾性研究采用分层整群抽样。根据家庭记录中的生长曲线，记录每个儿童身高和体重生长发育迟缓的发生时间。在下一阶段，使用重复事件模型（比例率模型），并借助SAS软件（版本9.2）对数据进行建模。
结果
根据比例率模型，母亲的教育水平对儿童身高和体重生长发育迟缓率的影响显著（P = 0.046，P = 0.049），父亲的工作仅对儿童体重生长发育迟缓有显著影响（P < 0.001）。然而，包括性别、出生顺序和纯母乳喂养状况在内的其他变量对儿童生长发育迟缓率的影响不显著。
结论
提高低收入家庭母亲的认识，同时改变受过教育的母亲对2岁以下儿童喂养所需技能和指导原则的态度，可被视为应对儿童生长发育迟缓的最重要方法。
