Bottom Line: Finally, a comprehensive model was devised to show how these factors relate to each other as well as to the body mass index (BMI) of the children simultaneously.Concerning the methodology of the current study, confirmatory factor analysis (CFA) was applied to reveal the hidden (secondary) effect of socioeconomic factors on feeding practice and ultimately on the weight status of the children and also to determine the degree of model fit.The comprehensive structural model tested in this study suggested that there are significant direct and indirect relationships among variables of interest.

ABSTRACT
The main objective of this study is to identify and develop a comprehensive model which estimates and evaluates the overall relations among the factors that lead to weight gain in children by using structural equation modeling. The proposed models in this study explore the connection among the socioeconomic status of the family, parental feeding practice, and physical activity. Six structural models were tested to identify the direct and indirect relationship between the socioeconomic status and parental feeding practice general level of physical activity, and weight status of children. Finally, a comprehensive model was devised to show how these factors relate to each other as well as to the body mass index (BMI) of the children simultaneously. Concerning the methodology of the current study, confirmatory factor analysis (CFA) was applied to reveal the hidden (secondary) effect of socioeconomic factors on feeding practice and ultimately on the weight status of the children and also to determine the degree of model fit. The comprehensive structural model tested in this study suggested that there are significant direct and indirect relationships among variables of interest. Moreover, the results suggest that parental feeding practice and physical activity are mediators in the structural model.

Mentions: For the first construct (socioeconomic status) as presented in Table 1, the CFA model did not indicate the adequate fit to the given data in terms of (χ2(13,379) = 28.417, P value <0.05, TLI = 0.893 and RMSEA = 0.117), but the other indices were acceptable. According to Hair et al. [24] and Byrne [23], standardized factor loading must meet these three criteria. First, each factor loading must be more than 0.5, also none of factor loadings must be neither negative nor more than one [24]. As presented in Figure 1, factor loading of individual income and employee maid were less than 0.5; therefore, these two items must be eliminated from the measurement model. Therefore, modified model for socioeconomic status would be presented as Figure 2.
