Subjective health legacy of the Chornobyl accident: a comparative study of 19-year olds in Kyiv

BMC Public Health 9(1):417 (2009) PMID 19919706

ABSTRACT: BACKGROUND: Since the Chornobyl accident in 1986, the physical health of exposed children in Ukraine has been monitored, but their perceived health has not been studied. This study examines health perceptions of Ukrainian adolescents exposed to radioactive fallout in utero or as infants, and the epidemiologic and Chornobyl-related influences on self-reported health. METHOD: We assessed three groups of 19-year olds in Kyiv: 262 evacuees from contaminated areas near the plant; 261 classmate controls; and 325 population-based controls. The evacuees and classmates were previously assessed at age 11. Structured interviews were conducted with the adolescents and their mothers (N=766), followed by general physical examinations (N=722) and blood tests (N=707). Proportional odds logistic regression and multi-group path analysis were the major statistical tests. RESULTS: The examination and blood test results were similar across groups except for a significantly elevated rate of thyroid enlargement found by palpation in evacuees (17.8%) compared former classmates (8.7%) and population-based controls (8.0%). In addition, four evacuees and one population control had had a thyroidectomy. Compared to controls, the evacuees rated their health the least positively and reported more medically diagnosed illnesses during the 5 years preceding the interview, particularly thyroid disease, migraine headache, and vascular dystony. The consistent risk factors (p perceptions argues in favor of developing risk communication programs for families rather than for mothers or adolescents as separate target groups.
