摘要: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 (P=0.046, P=0.049) and the effect of fathers’ job was significant only on growth failure in children’s weight (P<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.
