  1. * P value results of Z-score tests for differences in the proportional change in prevalence trends between the two data sources (i.e., sample general population survey compared to ANC surveillance) by socio-demographic groupings (e.g., those aged 15-19 years versus those aged 20-24 years) for round 1 to round 2 and round 2 to round 3 were highly non-significant (p value >0.10), except for HIV prevalence trends by educational status where p = 0.092. As there was no evidence for any differences in trends by socio-demographic groupings, these results are not presented.
  2. Men aged 15-16 years were ineligible to participate in rounds 1 and 2.
  3. In ANC surveillance, "Residence" indicates the location of the ANC clinic where the woman sought prenatal services and not necessarily where she resides.
