Development of Children in Iran: A Systematic Review and Meta-Analysis

View Article: PubMed Central - PubMed

ABSTRACT

Background:: In order to gain a better perspective of the developmental status of children in different regions of Iran, this study was carried out to determine the prevalence and the factors impacting child development in Iranian studies.

Materials and methods:: Articles published in Iranian and international journals indexed in the SID, PubMed, Scopus and Magiran databases from 2001-2015 were systematically reviewed using standard and sensitive keywords. After evaluating the quality of 155 articles in the initial search, 26 articles were analyzed according to the inclusion criteria. After investigations, meta-analysis was done for six studies and the results were combined using Random Effects model, and the heterogeneity of studies was evaluated using the I2 index. Data analysis was performed using STATA version 11.2.

Results:: Eagger & Beggs tests, respectively with 0/273 & 0/260 did not confirm the probability of publication bias in the data, but heterogeneity in studies was confirmed (p<0/001). On such basis, the pooled prevalence of developmental disorder based on Random Effect model was calculated to be 0.146, CI (0/107-0/184). The prevalence of developmental disorders in children in the studies reviewed was reported between 7 to 22.4%. The most important risk factors were in SES (Socio Economic Status) and Prenatal, Perinatal, Neonatal &Child groups.

Conclusion:: More extensive studies and early intervention with respect to causes of developmental delay in children seems necessary.

Mentions: The investigation conducted in 4 databases using the keywords resulted in 155 articles. Out of these articles, 4 articles were published in two separate journals or in two different languages. Owing to different reasons (Figure 1), 57 articles were excluded. Finally, 26 articles all of which remained in the final review given their minimum score of 15 out of 22 (Table 1) were evaluated according to STROB checklist by two researchers. Out of the final 26 papers, the methodology of 23 studies was descriptive (cross-sectional, analytical, correlational, comparative), 2 were case-control, and one was retrospective.
