Post-Arrival Health Screening in Karen Refugees in Australia

Abstract

ObjectiveTo document the prevalence of nutritional deficiencies, infectious diseases and susceptibility to vaccine preventable diseases in Karen refugees in Australia.DesignRetrospective audit of pathology results.SettingCommunity based cohort in Melbourne over the period July 2006–October 2009.Participants1136 Karen refugee children and adults, representing almost complete local area settlement and 48% of total Victorian Karen humanitarian intake for the time period.Main Outcome MeasuresPrevalence of positive test results for refugee health screening, with breakdown by age group (<6 years, 6–11 years, 12–17 years, 18 years and older).ResultsOverall prevalence figures were: anaemia 9.2%, microcytosis 19.1%, iron deficiency 13.1%, low vitamin B12 1.5%, low folate 1.5%, abnormal thyroid function tests 4.4%, vitamin D<50 nmol/L 33.3%, hypocalcaemia 7.4%, raised alkaline phosphatase 5.2%, abnormal liver transaminases 16.1%, hepatitis B surface antigen positive 9.7%, hepatitis B surface antibody positive 49.5%, isolated hepatitis B core antibody positive 9.0%, hepatitis C positive 1.9%, eosinophilia 14.4%, Schistosoma infection 7%, Strongyloides infection 20.8%, malaria 0.2%, faecal parasites 43.4%. Quantiferon-gold screening was positive in 20.9%. No cases of syphilis or HIV were identified. Serological immunity to vaccine preventable diseases was 87.1% for measles, 95% for mumps and 66.4% for rubella; 56.9% of those tested had seroimmunity to all three.ConclusionsKaren refugees have high rates of nutritional deficiencies and infectious diseases and may be susceptible to vaccine preventable diseases. These data support the need for post-arrival health screening and accessible, funded catch-up immunisation.

A Qualitative Study on Tobacco Smoking and Betel Quid Use Among Burmese Refugees in Australia

“…Burmese refugees in Australia are vulnerable to health issues such as mental stress [1], infectious diseases and nutritional deficiencies [2]. Anecdotal evidence from a non-government organisation that supports refugees (Strategic Community Assistance to Refugee Families (SCARF)) suggested that there are high rates of smoking among Burmese men in Wollongong.…”

Blood screen findings in a 2-year cohort of newly arrived refugees to Sydney, Australia

“…A high level of positive or indeterminate results for hepatitis C serology was noted in refugees from Myanmar, compared with previous studies. 12 Of the five individuals who were positive or indeterminate, four also had evidence of resolved hepatitis B infection. Hence, they appear to have been at significant risk of infection with bloodborne viruses.…”

Immunisation for refugees in Australia: a policy review and analysis across all States and Territories

“…Although there is growing evidence on under-immunisation among refugees, 8,10,17,18 there is limited data on systematic approaches for transforming such information into effective health policies to improve immunisation uptake. A thorough literature search was therefore firstly conducted to highlight critical issues to consider while developing immunisation policies for refugees.…”

“…Perhaps this can explain the existing lack of data on immunisation coverage rates for people of refugee background at a population level in Australia, 7 despite available evidence on small cohorts indicating they are under-immunised. 8,10,17,18 Lack of identifier mechanisms for refugees in population datasets compromises effective monitoring and surveillance as well as the evaluation of health-related policies for this subgroup. 40 The identification of Aboriginal and Torres Strait Islander children on the ACIR has been integral in monitoring immunisation coverage and meeting targets of high immunisation coverage among this group.…”
