[The serum markers in the pregnant population of the basic health area of El Natahoyo (Gijón)].
OBJECTIVE
To find the prevalence of markers of rubeola, Toxoplasma, lues, HIV and hepatitis A, B and C viruses in the pregnant women of a health district; and these markers' correlations with epidemiological and socio-demographic antecedents.


METHODS
129 pregnant women from the 5.3 Health District in Asturias with birth predicted for between August 1994 and October 1995. A descriptive study of epidemiological, socio-demographic and serological data; statistical calculation with RSigma.


RESULTS
109 pregnant women (84.5%) were assessed, average age 28.6, including 9 abortions with path. analysis in the first three months. HIV was tested in 15 cases, all negative. Toxoplasma was positive in 46 cases, with no association with other variables. Rubeola was negative in 6 cases, all > 25 years old, with overall vaccination coverage of 42.2% and 64.7% for < 26-year-olds. One case of lues was found. The HC test was negative in all the pregnant women, with 4% of HBsAg+, related to being gypsy and to AF of hepatopathy. HA IgG was positive in 52 cases (52%) and more common among gypsies vs. the rest. In the latter group there was increasing prevalence according to age.


CONCLUSIONS
1) HIV screening is not common. 2) There is a high percentage of pregnant women with no immunity to Toxoplasma. 3) Low rubeola vaccination coverage among women under 26 was found. 4) There is a higher percentage of HBsAg+ cases in comparison with other areas, but not with the HC virus. 5) A high percentage of cases had no previous contact with the HA virus.
