AB OBJECTIVE: To determine the seroconversion rate for HIV-1 among
inductees to the Royal Thai Army during their service. METHODS: Two
cohorts of 21 y/o men who were seronegative at induction into the Royal
Thai Army in Nov 91 (n = 8,898) and May 92 (n = 8,701) were followed at
intervals to determine the incidence of HIV-1 infection during 2 year
follow-up. Diagnosis of HIV was made by EIA and by Western Blot. Three
geographic areas in Thailand were studied, Bangkok Metropolitan
Administration (BMA), the Upper North (UN) and the Lower North (LN).
RESULTS: Through Aug 93, the average follow-up was 55% for the Nov 91
cohort and 46% for the May 92 cohort. The combined incidence of HIV-1
infection for the 2 cohorts was 211/16,455 person-year (py) (1.28%/py).
Incidence in BMA was significantly lower than in the two northern areas
(BMA = 0.59%/py, RR = 1; LN = 0.95%/py, RR = 1.63; UN = 3.27%/py, RR =
5.59). The lowest incidences were seen in 2 provinces in the LN. The
highest incidence was in Phayao (6.16%/py) in the UN. Significantly
lower incidences were found in inductees who were married at induction
(married = 0.6%/py, RR = 1; not married = 1.48%/py, RR = 2.49) and in
those with more than primary school education (PSE) (PSE = 1.45%/py, RR
= 1.57; > PSE = 0.92%/py, RR = 1). CONCLUSIONS: The incidence of HIV-1
infection is very high in inductees beginning service in the Royal Thai
Army. Incidence is higher in regions where prevalence in inductees is
highest, especially the UN.
