Prevalence and factors associated with human brucellosis in livestock professionals.

Abstract The objective of this study is to estimate the seroprevalence of human brucellosis in livestock professionals and analyze the factors associated with brucellosis focusing on sociodemographic variables and the variables of knowledge and practices related to the characteristics of the activities carried out in livestock.

AB  - OBJECTIVE: The objective of this study is to estimate the seroprevalence of human
      brucellosis in livestock professionals and analyze the factors associated with
      brucellosis focusing on sociodemographic variables and the variables of knowledge
      and practices related to the characteristics of the activities carried out in
      livestock. METHODS: This is a cross-sectional seroepidemiological study with a
      population of 131 workers of butchers, slaughter rooms, and slaughterhouse and
      192 breeders sampled randomly in Namibe province, Angola. The data were obtained 
      from the collection of blood and use of questionnaires. The laboratory tests used
      were rose bengal and slow agglutination. The questionnaire allowed us to collect 
      sociodemographic information and, specifically on brucellosis, it incorporated
      questions about knowledge, attitudes, and behaviors of livestock professionals.
      In addition to the descriptive statistical approach, we used the Chi-square test 
      of independence, Fisher's test, and logistic regression models, using a
      significance level of 10%. RESULTS: The general weighted prevalence of
      brucellosis was 15.6% (95%CI 13.61-17.50), being it 5.3% in workers and 16.7%
      (95%CI 11.39-21.93) in breeders. The statistical significance was observed
      between human seroprevalence and category (worker and breeder) (p < 0.001) and
      education level (p = 0.032), start of activity (p = 0079), and service location
      (p = 0.055). In a multivariate context, the positive factor associated with
      brucellosis in professionals was the professional category (OR = 3.54; 95%CI
      1.57-8.30, related to breeders in relation to workers). CONCLUSIONS: Human
      brucellosis in livestock professionals is prevalent in Namibe province (15.6%),
      where the professional category was the most important factor. The seroprevalence
      levels detected are high when compared with those found in similar studies.
      OBJECTIVO: Estimar a seroprevalencia da brucelose humana em profissionais da
      pecuaria e analisar os factores associados a brucelose com foco em variaveis
      sociodemograficas, de conhecimento e praticas relativas as caracteristicas das
      actividades desenvolvidas na pecuaria. METODOS: Estudo transversal
      seroepidemiologico em populacao de 131 trabalhadores de talhos, salas de abate e 
      matadouro e 192 criadores amostrados aleatoriamente na provincia do Namibe,
      Angola. Os dados foram obtidos por meio de colheita de sangue e aplicacao de
      questionario. Os testes laboratoriais utilizados foram o Rosa de Bengala e a
      aglutinacao lenta em tubos. O questionario permitiu recolher informacao
      sociodemografica e, especificamente sobre a brucelose, incorporou questoes sobre 
      conhecimento, atitudes e comportamentos dos profissionais da pecuaria. Alem da
      abordagem estatistica descritiva, foram utilizados os testes de Independencia do 
      Qui-quadrado, Fisher e modelos de regressao logistica, utilizando um nivel de
      significancia de 10%. RESULTADOS: A prevalencia geral ponderada da brucelose foi 
      de 15.6% (IC95% 13.61-17.50), sendo 5.3% em trabalhadores e 16.7% (IC95%
      11.39-21.93) em criadores. A significancia estatistica foi observada entre a
      seroprevalencia humana e a categoria (trabalhador e criador) (p < 0.001) e o
      nivel de instrucao (p = 0.032), inicio de actividade (p = 0.079) e local de
      servico (p = 0.055). Em um contexto multivariado, o factor positivamente
      associado a brucelose em profissionais foi a categoria profissional (OR = 3.54;
      IC95% 1.57-8.30, relativo aos criadores em relacao a trabalhadores). CONCLUSOES: 
      A brucelose humana em profissionais da pecuaria e prevalente na provincia do
      Namibe (15.6%), onde a categoria profissional foi o factor mais relevante. Os
      niveis de seroprevalencia detectados sao elevados se comparados com outros
      encontrados em estudos semelhantes.
