title: Cervical cytology screening in Vietnamese asylum seekers in a Hong Kong detention center. Population demographics and historical perspectives.
abstract: OBJECTIVE
  To provide a brief review of the history and demographics of the Vietnamese asylum-seeking population in Hong Kong and their possible effects on the initiation of a cervical cytology screening program at a Hong Kong detention center.
  
  
  METHODS
  Analysis of case histories, questionnaires and interviews with women in a detention center identified demographic features related to Pap smear history, knowledge of the Pap test, age at first intercourse and cigarette smoking status among women aged 17 years and over. Analysis of Pap smear uptake following initiation of a screening program was undertaken.
  
  
  RESULTS
  Of the 1,171 women in the detention center who were eligible for a Pap smear, 536 (45.8%) actually obtained one, although enrollment, which was strong at the initial offering, slowed considerably as the program progressed. None of the women had had a Pap smear prior to leaving Vietnam. Knowledge of the utility and risk status criteria for Pap testing was very limited. The majority (77.9%) of the subjects started sexual activity after age 20 years, and three (0.6%) smoked. There were four (0.2%) abnormal smears identified among those tested.
  
  
  CONCLUSIONS
  Convincing evidence was obtained that the Pap test was not widely used in Vietnam among the asylum-seeking population, and its role in preventing cervical cancer was not well known to the women studied. The initial strong uptake of the Pap smear was not maintained. That may be attributable to psychosocial factors associated with detention under harsh conditions and trauma associated with fleeing Vietnam.
