OBJECTIVE
To determine the prevalence of tuberculosis infection in school children from Tijuana, Mexico.
MATERIAL AND METHODS
A study sample was randomly chosen from the municipal school registry and 1,131 elementary and high school children were included. All received one doses of PPD 5TU (Mantoux). Subjects with induration > or = 10 mm were considered positive reactors.
RESULTS
The overall prevalence of positive reactors was 57%. The proportion of positive reactors was significantly higher among BCG-immunized subjects than in non-immunized individuals (59.7 vs 45.6%; p < 0.001). Correlation was not significant between age of immunization with BCG and diameter of induration.
CONCLUSIONS
The prevalence of tuberculosis infection in Tijuana is extremely high; this fact has important implications in the control of tuberculosis in this region.
目的
确定墨西哥蒂华纳市学童的结核感染率。
材料与方法
从市学校登记册中随机选取研究样本，纳入1131名小学和中学儿童。所有人均接种一剂5结核菌素单位的纯蛋白衍生物（曼托试验）。硬结直径大于或等于10毫米的受试者被视为阳性反应者。
结果
阳性反应者的总体患病率为57%。卡介苗免疫受试者中的阳性反应者比例显著高于未免疫个体（59.7%对45.6%；p<0.001）。卡介苗免疫年龄与硬结直径之间的相关性不显著。
结论
蒂华纳市的结核感染率极高；这一事实对该地区的结核病控制具有重要意义。
