It matters what you measure: a systematic literature review examining whether young people in poorer socioeconomic circumstances are more at risk of chlamydia.

摘要: Background England has invested in chlamydia screening interventions for young people. It is not known whether people poorer socioeconomic circumstances (SEC) are at greater risk of and therefore need screening. Objective To conduct a systematic review examining variations prevalence or positivity Data sources Eight bibliographic databases using terms related to SEC, supplemented by website reference searches. Eligibility Studies published 1999–2011 North America, Western Europe, Australia New Zealand, including populations aged 15–24 years, with diagnosed nucleic acid amplification testing. Appraisal synthesis Two reviewers independently screened references, extracted data, appraised studies meeting inclusion criteria rated as high, medium low according their quality relevance. Socioeconomic were synthesised medium/high-rated only. Results No high-rated identified. medium-rated reported SEC. In 6/8 studies, was higher Associations more often significant when measured education than other indicators. All measuring low. Across all methodological limitations SEC measurement Conclusions The current literature limited its capacity describe associations between risk. choice measure may explain why some find disadvantaged while others do not. appropriate indicators (eg, education) needed inform decisions about targeting
