Post traumatic stress disorder in children after tsunami disaster in Thailand: 2 years follow-up.

BACKGROUND: On December 26, 2004, the tsunami destroyed many families, communities, and residential areas. Adverse psychological impact on children and adolescents due to a natural disaster of this magnitude has never been reported in Thailand's history particularly as Post-Traumatic Stress Disorder (PTSD). OBJECTIVE: Investigate clinical symptoms and develop a 2-year monitoring and intervention program for PTSD in children affected by the December 26, 2004 tsunami natural disaster The study period started six weeks after the event and was completed after two years. MATERIAL AND METHOD: One thousand six hundred and twenty five surviving students from two schools in Takuapa district, Phang-nga Province, were enrolled. Screening tests using Pediatric symptom checklists, Childhood depressive intervention (CDI), and Revised child impact of events scales (CRIES) were done. Psychiatric evaluations were done by child and adolescent psychiatrists. Post Traumatic Stress Disorder (PTSD) was diagnosed using criteria from Diagnostic and Statistical Manual of Mental Disorders, 4th edition. RESULTS: The prevalence of PSTD in the affected students were 57.3, 46.1, 31.6, 10.4, and 7.6% at 6 weeks, 6 months, 1 year, 1 1/2 years, and 2 years, respectively. The female: male ratio was 1.7:1. The peak age was 9-10 years old. Threatened situations were studied. Of the 176 students who risked their lives in the waves, 48 (27.3%) suffered from PTSD. Meanwhile, of the 1314 students who were not hit by the waves but were among affected friends and relatives, 42 students (3.1%) suffered from PTSD. The prevalence of PTSD in those hit by the waves were significantly higher than those who were not [p-value < 0.01, RR = 5.16 (4.04-.6.6)]. CONCLUSION: The prevalence of PSTD in children who suffered from the tsunami disaster was as high as 57.3% at six weeks after the incident. It declined sharply at two years (7.6%) with the help of integrated welfare. The children continue to get financial, rehabilitation, and mental health support to prevent long-term adverse outcomes.

Trend study of autistic spectrum disorders at Queen Sirikit National Institute of Child Health.

BACKGROUND: Increases in the incidence and prevalence of autistic spectrum disorders have been reported recently in the United States and Europe, but there are only a few reports on the trend of this problem in Thailand. OBJECTIVES: To study trend in autistic spectrum disorder patients and to find the factors that correlate with the incidence of this disorder at Queen Sirikit National Institute of Child Health. MATERIAL AND METHOD: A hospital-based prospective trend study was conducted in patients aged less than 12 years old, who attended the Child and Adolescent Department, Queen Sirikit National Institute of Child Health, Bangkok, form January 1998 to December 2002. Autistic spectrum disorders were defined as autistic disorder pervasive developmental disorder-not otherwise specified (PDD-NOS), and Asperger's disorder Related factors were recorded and analyzed Aged-adjusted incidence rate in both sexes and proportion rates of related factors were calculated by using the direct method Standard t-test and correlation coefficient were performed to test for statistically significant difference in the prevalence rate in each group. RESULTS: There were 610 new patients aged less than 12 years who displayed behavior consistent with autistic spectrum disorders. The increasing trend in the incidence of autistic spectrum disorder is observed (r = 0. 935, p = 0. 02). The incidence rate of autistic spectrum disorders among out patients less than 12 years has increased from 1.43 per 10, 000 in 1998 to 6.94 per 10, 000 in 2002. The correlation factors "an only one child in the family" is observed (r = 0.9, p = 0.038). CONCLUSION: During the 5 years of the study, a significant increase in the incidence of autistic spectrum disorders was observed at Queen Sirikit National Institute of Child Health. Increase in the incidence of ASD in this center cannot explain by any solid evidence from the present study.
