Risk factors for sporadic listeriosis: A systematic review and meta-analysis

Listeriosis is a major public health concern associated with high hospitalization and mortality rates. The objective of this work was to summarize evidence on the associations between risk factors sporadic cases by meta-analysing outcomes from currently published case-control studies. Suitable scientific articles were identified through systematic literature search, subjected methodological quality assessment. From each study, odds-ratio (OR) measures as well study characteristics such population type, design, type model factor hierarchy extracted. Mixed-effects meta-analysis models adjusted appropriate data partitions. Twelve primary studies investigating listeriosis conducted 1985 2013 passed assessment stage. These provided 226 OR considered for meta-analysis. According meta-analysis, main acquiring suffering an immunocompromising disease. In relation food exposures, confirmed known consumption RTE dairy, seafood processed meat underlined new vehicles fruits vegetables, recently involved in outbreaks. There not enough appraise travel, animal-contact person-to-person transmission pathways listeriosis. results will allow refining aim improving characterisation susceptible population.
