Passive smoking linked with TB risk in children

Thursday, April 5, 2007

NEW YORK (Reuters Health) - A study conducted in South Africa
suggests there is an association between passive smoking and
increased risk of Mycobacterium tuberculosis infection in children
living in a home with a tuberculosis patient.

"Tuberculosis and smoking are both significant public health
problems," Dr. Saskia den Boon, of KNCV Tuberculosis Foundation, The
Hague, Netherlands, and colleagues write in the April issue of
Pediatrics. The possible association between passive smoking and TB
infection in children "is a cause of great concern, considering the
high prevalence of smoking and tuberculosis in most developing
countries."

The team conducted a community survey that included 15 percent of the
addresses in two adjacent low- to middle-income suburbs in Cape Town.
All children younger than 15 years of age and their adult household
members living at the addresses were included in the study.

All of the children received a tuberculin skin test, with M.
tuberculosis infection defined as a reaction of at least 10 mm. The
team defined passive smoking as living in a home with at least one
adult who smoked for at least 1 year.

A total of 1344 children were included in the analysis. Of these, 432
(32 percent) had a positive tuberculin skin test and 1170 (87
percent) were classified as passive smokers.

The rate of positive tuberculin skin tests was 34 percent in children
with a smoker in the home compared with 21 percent in those who were
not passive smokers. The difference was not statistically significant.
However, there was a significant association between passive smoking
and a positive tuberculin skin test in the 172 households that had
with a patient with tuberculosis. Children living in these conditions
were nearly five-times as likely to test positive.

"Passive smoking might affect the immune system of the child, thus
increasing the risk of getting infected," den Boon and colleagues
suggest. Tobacco smoke exposure alters cell function, such as
lowering the rate of clearance of inhaled substances and abnormal
permeability of cells and blood vessels.

The investigators note that "in many developing countries with a high
burden of tuberculosis, the prevalence of smoking is rapidly
increasing, especially among women." The proportion of women who
smoke is particularly worrisome, they add, "because they expose their
children to tobacco smoke."
