The 2007 Zambia Demographic Health Survey (ZDHS) HIV/AIDS data was used to investigate the
attitude of people to HIV/AIDS patients in Zambia using the generalized additive mixed model. The
model was used to simultaneously measure the fixed, nonlinear and random effects. The fixed effects of
categorical covariates were modelled using the diffuse prior, P-spline with second-order random walk
for the nonlinear effect of continuous variable while the exchangeable normal priors were used for the
random effects of the district. The Binomial distribution was used to handle the dichotomous nature of
the three dependent variables considered. The dependent variables are stigmatization towards relative
sick with HIV/AIDS, teacher who has HIV/AIDS but is not sick and a food vendor who has HIV/AIDS.
We found that the people who seem to be responsible for discriminatory attitude towards PLWHA in
Zambia are predominantly those who stay in the Southern and Lusaka provinces, the urban areas, who
are from at least the middle class wealth index, elite, age 20+ and who either are married/living together
with partner.
