RESUMO

OBJETIVO: Este estudo objetivou identificar a soroprevalência da doença celíaca em adolescentes de escolas públicas da cidade de Salvador, Bahia. MÉTODO: Trata-se de um estudo transversal com amostra probabilística de 1.213 adolescentes de 11 a 17 anos, de ambos os sexos. O índice de massa corporal foi utilizado para o diagnóstico do estado nutricional, adotando-se os percentis segundo idade e sexo, propostos pela World Health Organization. O anticorpo anti-transglutaminase humana da classe imunoglobulina A (anti-tTG-IgA) foi adotado como teste sorológico para triagem da doença celíaca e foi determinado pela técnica do ensaio imunoabsorvente ligado à enzima (ELISA). Foi realizada análise descritiva, utilizando-se a proporção e a média (desvio padrão). RESULTADOS: O sexo feminino predominou entre os adolescentes, e a maioria encontrava-se com adequado estado nutricional. O anticorpo anti-tTG-IgA foi positivo em 6/1.213 (0,49%) adolescentes. CONCLUSÃO: A soroprevalência de doença celíaca entre os adolescentes estudados foi 0,49%. Novas investigações são necessárias para confirmar a prevalência de doença celíaca nessa faixa etária. .


OBJECTIVE: This study aimed to identify the seroprevalence of celiac disease in adolescents from public schools in the city of Salvador, Bahia. METHODS: This was a cross-sectional study with probabilistic sample of 1,213 adolescents, aged 11 to 17 years old, of both genders. The body mass index was used to determine the participants' nutritional status based on the percentiles for age and gender recommended by the World Health Organization. Measurement of the anti-human transglutaminase immunoglobulin A (anti-tTG-IgA) antibody was established as the specific screening test for celiac disease, which involved an enzyme-linked immunosorbent assay (ELISA). Descriptive analysis was performed using proportions and means (standard deviation). RESULTS: The female gender prevailed in the sample, and most of the participants had normal weights. The anti-tTG-IgA antibody was positive in 6/1,213 (0.49%) adolescents. CONCLUSION: The seroprevalence of celiac disease was 0.49% in the investigated adolescents. Further studies are necessary to establish the prevalence of celiac disease in this age range. .
