The prevalence and socio-biological relations of bacteriuria in Trinid
adian pregnant women were investigated The prevalence of bacteriuria w
as found to be 16.7% and it was more common in the 30 - 39 year age gr
oup, among parous women, among Negroes, and in patients with a low fam
ily income and overcrowded living conditions. Symptoms were present in
19% of bacteriuric patients and almost one third gave a past history
of urinary tract infection. Only 10% had been previously exposed to se
xually transmitted diseases such as syphilis, gonorrhoea and herpetic
genital infections. Because of the serious consequences to mother and
foetus, we advocate quantitative urine cultures for all antenatal pati
ents, especially those coming from disadvantaged socio-economic condit
ions.
