The association between public transportation for commuting and pulmonary tuberculosis TB was analyzed in workers in Lima, Peru.

Traveling in minibuses was a risk factor for pulmonary TB. Preventive measures need to be taken by health services to prevent spread of this disease. Tuberculosis TB continues to be enfermedadea important public health problem in impoverished areas 1 — 4. It is spread through the air by patients with pulmonary TB 5. Because those most affected by pulmonary TB are persons 15—50 years of age, employment-related characteristics of these enfermedxdes must be taken into account when studying this disease.

Public Transportation and Pulmonary Tuberculosis, Lima, Peru

In Lima, Peru, residents of peripheral neighborhoods generally use minibuses to travel to work or school and have long commute times. Because public transportation in Latin America routinely carries preu passengers than permitted by law, it is plausible to assume that in areas with endemic pulmonary TB, daily use of public transportation may be a risk factor for acquiring TB 6 — 9.

The greatest amount of expectoration productive coughing occurs emergentfs the morning commute 6: Given the conditions in which persons travel to work in Lima emergebtes travel times and overcrowding on minibuses with closed windowswe analyzed whether use of minibuses was associated with the spread of pulmonary TB as part of a larger study to assess pulmonary TB in the Ate-Vitarte District of this city.

It is a marginal urban area that receives immigrants who come to Lima with high rates of TB. A total of persons agreed to participate: Informed consent was obtained from all participants. Interviews were conducted ell the health services that persons visited.

We obtained demographic and socioeconomic information, as well as information on perceived health, and means of transportation used in commuting. All persons with productive coughs were requested to reemergentew 3 sputum samples the first immediately after the interview and the other 2 on 2 consecutive days for smear testing.


Samples were tested by using the Ziehl-Neelsen method, which is used in all epidemiologic surveillance in Peru Demographic and socioeconomic characteristics of the study group are shown in Table 1. Variables analyzed for persons tested for pulmonary TB are shown in Table 2. None of the demographic and socioeconomic indicators analyzed Table 1 were associated with rn TB.

Table 2 shows crude associations between variables and pulmonary TB.

Adjusted relationships obtained by logistic regression that controlled for all variables shown in Table 2 confirmed that commuting to work by minibus was associated with a positive test result for pulmonary TB adjusted odds ratio 4. The proportion of persons 15—44 years of age with pulmonary TB in our study was consistent with data of the World Health Organization and the Peruvian Ministry of Health, which show that this age group has the highest prevalence of this disease 513 Our results also showed that there were no sex-related differences in the frequency of pulmonary TB 13 Socioeconomic variables showed no association with pulmonary TB.

However, this finding should be interpreted cautiously because of the small sample size, particularly the number of persons who lived in extreme poverty. Another factor that could limit our conclusions is accessibility of persons in areas of extreme poverty to public transportation. The fact that the field work phase of our study could not be increased because of shortages of resources and health center personnel time is also a limitation.

The relationship of having pulmonary TB with working at home or away from home showed a positive prevalence ratio of 6.

Among persons working outside the home, commuting by minibus increased the risk of having pulmonary TB by a factor of 4.

Minibuses in Lima increase the risk for pulmonary TB because they are usually overloaded capacity is often doubled in the early morning and late evening.

Overcrowding, exposure to persons with productive coughs while commuting 2 times a day 5 days a week, and u windows on minibuses, combined with a high prevalence emfrgentes pulmonary TB in Lima, increase the risk of acquiring this disease.


Because persons with cases of pulmonary TB have more productive coughs in the morning when more bacilli are released because of their accumulation at nightthere is increased risk for transmission of TB to other perru 15as has already been suggested by other studies in developing and industrialized countries 6 — 9. Despite the limitations of our study, commuting in minibuses was a risk factor for pulmonary TB. Consequently, preventive measures need to be taken by health services to encourage persons with productive coughs to avoid this type of public transportation and to come to health services for diagnosis and treatment.

Health services should also be more accessible reemeegentes persons with pulmonary TB who, for whatever reason, cannot use other forms of transportation. This increased accessibility would include home treatment during the infectious phase of this disease.
