Abstract: | Investigation on seroprevalence and risk factors of Toxoplasma gondii infections among indigenous and immigrant pregnant women in Mid-Taiwan showed that anti Taxoplasma-specific IgG antibody counts were significantly higher in indigenes (40.6%) than in immigrants (18.2%), with an odds ratio
of OR = 3.34 (95% CI: 1.93–4.80). The titre of Taxoplasma-specific IgG was also significantly higher in indigenes than in immigrants (P < 0.001). Differences of living styles for Toxoplasma infection between the two groups were drinking untreated water (OR = 2.34, 95% CI: 1.36–4.02), consumption of raw/undercooked
meats (OR = 10.11 95% CI: 4.92–20.78), especially raw/undercooked pork (P = 0.000), or raw/undercooked viscera (OR = 9.16, 95% CI: 2.97–27.94), contact with cats (OR = 5.69, 95% CI: 2.83–11.47),
or soil (OR = 2.55 95% CI: 1.72–3.80). Differences of risk factors for Toxoplasma infection in terms of positive IgG in the two groups were consumption of raw/undercooked meats (P = 0.005) especially raw/undercooked pork (P = 0.004), and contact with cats (P = 0.013) or soil (P = 0.028). It is concluded that seroprevalence of Toxoplasma infection is higher in indigenous pregnant women and related to their living styles. To prevent congenital toxoplasmosis,
health education seems required. |
