Population attributable risk fraction of modifiable risk factors associated with poor self-rated health among children and adolescent; the CASPIAN-V study.

Background: We aimed to determine the population attributable risk fraction (PARF) of the risk factors for poor SRH in Iranian children and adolescents.
Method: This was a nationwide cross-sectional study conducted in 2015 among 14,400 students aged 6-18 years, living in 30 provinces of Iran. Data were collected using global school health survey questionnaire. Logistic regression was employed to determine the adjusted association of modifiable risk factors with SRH. We used average PARF to determine the preventable proportion of poor reported SRH.
Results: Of 14,400 recruited students, data on 13,983 subjects were analyzed in current study. The mean (SD) age of participants (n = 13,983) was 12.3 (3.16) years, and 49.3% were female. Poor SRH was reported in 19% of subjects. In total, 77% of poor reported SRH in Iranian children and adolescents could be attributed to insufficient daily sleep duration, physical injury, lack of close friend, dissatisfaction with family relationship, and the lack of a companion to share personal problems. We also found that physical pain had the largest PARF (32.4%) followed by anxiety (26.1%) and un-satisfaction with family relationship (5.2%).
Conclusion: The established physical and social support factors of poor SRH were associated with a remarkable proportion of poor SRH in the Iranian pediatric population. Changing the children's risk factor profile to the lowest physical risk factor as well as reducing the anxiety level and preventing from physical painsmay significantly improve the SRH of children and adolescents.
