  1. The HIV epidemic in Zambia : socio-demographic prevalence patterns and indications of trends among childbearing women.

    Article - En anglais

    Objective 

    To examine socio-demographic HIV prevalence patterns and trends among childbearing women in Zambia.

    Design 

    Repeated cross-sectional surveys.

    Methods 

    Personal interviews and unlinked anonymous testing of blood samples of women attending antenatal care in selected areas.

    Results 

    The 1994 data includes information from 27 areas and a total of 11 517 women.

    The HIV prevalence among urban residents appeared with moderate variation at a very high level (range 25-32%, comparing provinces).

    The geographical variation was more prominent in rural populations (range 8-16%) and was approximately half the prevalence level of the urban populations.

    With the exception of the 15-19 years age-group, HIV infection was found to rise sharply with increasing educational attainment (odds rratio, 3.1 ; confidence interval, 2.6-3.8) when contrasting extreme educational levels.

    Although the assessment of trends is somewhat restricted, the available information indicates stable prevalence levels in most populations over the last 2-4 years.

    Conclusions 

    The data showed extremely high HIV prevalence levels among childbearing women.

    Longer time-intervals between surveys are needed, however, in order to verify the stability in prevalence identified by this study.

    The tendency to changing differentials by social status is suggested as a possible sign of an ongoing process of significant behavioural change.
