Resumo: | OBJECTIVE: To evaluate possible adverse reproductive outcomes in an area adjacent to a petrochemical plant in southern Brazil. METHODS: A review of 17,113 birth records of the main hospital of the municipality of Montenegro, southern Brazil, from 1983 to 1998 was carried out. Three groups of cases were selected: (1) newborns with major congenital malformations; (2) newborns with low birth weight (;500 g). A control was assigned to each case. Controls were the first newborns weighing >; or = 2,500 g without malformations and of case-matching sex. Mother's residence during pregnancy was used as an exposure parameter. Statistical analyses were performed using Chi-square test or Fisher test, odds ratio, 0.05 significance level, and 95% confidence interval. RESULTS: For unadjusted analysis, it was found a correlation between low birth weight and geographical proximity of mother's residence to the petrochemical plant (OR = 1.66; 95% CI = 1.01--2.72) or residence on the way of preferential wind direction (OR = 1.62; 95% CI = 1.03--2.56). When other covariates were added in the conditional logistic regression (maternal smoking habits, chronic disease and age), there was no association. CONCLUSIONS: Despite final results were negative, low birth weight could be a good parameter of environmental contamination and should be closely monitored in the studied area. |

OBJETIVO: Avaliar os possíveis riscos reprodutivos em uma região próxima a pólo petroquímico situado no Rio Grande do Sul. MÉTODOS: Foram analisados 17.113 registros de nascimentos ocorridos no principal hospital da região, localizado no município de Montenegro, RS, desde 1983 até 1998. Foram selecionados três diferentes grupos de casos: (1) recém-nascidos portadores de malformações congênitas maiores; (2) recém-nascidos com baixo peso ao nascer (;500 g). Para cada caso, foi atribuído um controle específico, que foi a primeira criança nascida viva, pesando 2.500 g ou mais, com ausência de malformações e tendo o mesmo sexo que o caso em questão. A residência materna durante a gravidez foi utilizada como um parâmetro para exposição. Para a análise estatística, foram usados os testes qui-quadrado ou Fisher, "odds ratio", nível de significância de 0,05 e intervalo de confiança de 95%. RESULTADOS: Foi encontrada correlação positiva para baixo peso ao nascer e para proximidade geográfica da residência materna ao Pólo Petroquímico ["odds ratio" (OR) = 1,66; 95% confidence interval (CI) = 1,01-2,72] ou residência na direção preferencial do vento ["odds ratio" (OR) = 1,62; 95% confidence interval (CI) = 1,03-2,56]. Quando outras variáveis foram incluídas na análise de regressão logística condicional (fumo, doenças crônicas e idade materna), essa associação desapareceu. CONCLUSÕES: Apesar de os resultados finais terem sido negativos, o baixo peso ao nascer pode ser um bom parâmetro para medir a contaminação ambiental, mas deve ser monitorado na região estudada.
