Immunization coverage of Australian-born children of Arabic-speaking background in Central Sydney
1Division of General Practice, Central Sydney Area Health Service, Balmain, New South Wales, Australia.
Insights
Australian children from Arabic-speaking backgrounds in Central Sydney show high immunization coverage rates, with 94.3% fully immunized according to verifiable records. This study highlights successful vaccination strategies within this community.
Area of Science:
- Public Health
- Pediatrics
- Epidemiology
Background:
- Arabic-speaking communities represent a significant demographic in Central Sydney.
- Understanding immunization coverage is crucial for maintaining herd immunity and preventing vaccine-preventable diseases.
- Previous data on immunization rates within specific ethnic groups in Australia is limited.
Purpose of the Study:
- To determine the immunization coverage rates for Australian-born children aged 12-36 months from an Arabic-speaking background in Central Sydney.
- To compare parental reports of immunization status with documentary evidence.
- To identify factors contributing to high or low immunization rates in this population.
Main Methods:
- A cross-sectional study was conducted using hospital birth records to identify eligible children.
- Eligibility criteria included maternal country of birth (Arabic-speaking) and child's residence (Central Sydney).
- Data on immunization status was collected via parental questionnaires and verified with personal health records and service provider documentation.
Main Results:
- Parents reported a 97.6% full immunization rate.
- Documentary evidence confirmed a 94.3% age-appropriate full immunization rate (95% CI 92.0-96.6).
- General practitioners administered the majority of immunizations (76.2%).
Conclusions:
- Despite challenges in contacting all identified children, the study sample is likely representative of the target population.
- Children from Arabic-speaking backgrounds in Central Sydney exhibit high immunization coverage.
- Further research into the successful strategies employed by this community could inform interventions for other ethnic groups.
Objectives:
To examine the immunization coverage rates of 12-36-month-old Australian-born children from an Arabic-speaking background in Central Sydney as determined by parental report and documentary evidence.
Methodology:
Eligible children were identified by examination of the records of five hospitals. Eligibility criteria were that the mother gave an Arabic speaking country of birth and a Central Sydney post code (as her place of residence) and the child was born between 1 May 1994 and 30 April 1996. Parents of all eligible children were invited to participate, either by a special appointment to answer a structured questionnaire, or by telephone survey. Of the 1157 eligible children identified from hospital birth records, only 641 could be contacted, of whom 584 (91.1%) agreed to participate. Full information on age appropriate immunization rates, as reported by parents and documented in records, could be assessed for 403 children.
Results:
Parents reported that 97.6% of children were fully immunized. When the child's immunization status could be verified from either the child's personal health record and/or the service provider, the rate of full, age-appropriate immunization was 94.3% (95% confidence intervals 92.0-96.6) compared to a parent-reported rate of 98.0%. General practitioners provided 76.2% of immunizations.
Conclusion:
While a substantial proportion of children identified from birth records could not be contacted, comparisons with census data and other analyses indicate that this sample is likely to be representative of the general population of 12-36-month-old Australian-born children from an Arabic-speaking background. This group appeared to be highly immunized. Further studies examining why the rates for this ethnic group are high in Central Sydney may determine strategies which will enhance immunization rates in other communities.
