Sociodemographic profile of children with Kawasaki disease in North India.

Kawasaki disease (KD) is now the commonest cause of acquired heart disease in children in developed countries. KD occurs all over the world, including developing countries. The present study steps out to explore our hypothesis, driven by clinical observation over the last 18 years, whether children with KD in North India are of a higher socioeconomic status than children with other rheumatologic diseases. One hundred consecutive children with KD, registered in Pediatric Rheumatology Clinic before January 2011, were enrolled as cases. Children with other rheumatologic diseases were taken as controls. Assessment of socioeconomic status was done by administering the Aggarwal scale. Data were collected through interview. Statistical analysis was done using SPSS package version 16. On univariate analysis, male sex, higher educational status of parents, urban residence, immunization status being complete, and higher scores on Aggarwal scale were found to be significantly associated with KD. On multivariate analysis, only male sex and urban residence were found to be significantly associated with KD (p < 0.001). Families of children with KD tend to have a better sociodemographic profile when compared with other pediatric rheumatologic disorders in North India. These results, however, need to be replicated in a multicentric study for any firm conclusions to be drawn.
