THE ASSOCIATION OF HOUSING DENSITY, ISOLATION AND TUBERCULOSIS IN
CANADIAN FIRST NATIONS COMMUNITIES
Background: First Nations communities experienced high levels of overcrowded housing,
degree of isolation and rates of tuberculosis TB. A study was done to assess the
association of between housing density, isolation and the occurrence of TB in First
Nations communities.
a combination of malnutrition, confinement on crowded reservations with poor sanitation,
and lack of immunity to the TB bacillus contributed substantially to this epidemic.
overcrowded housing can increase exposure of susceptible people to those with infectious
respiratory disease, and in doing so may increase the probability of transmission
Analyses show TB incidence higher in communities isolated from health services
data was collected from the seven First Nations and Inuit Health Branch who were living
on-reserve
All forms of TB was included in the analyses including pulmonary and extra pulmonary,
the federal cases of TB was defined as : (1) cases with M .tuberculosis demonstrated by
microscopy and/or on culture (2) if there is no bacterial proof, cases are analyzed to see if
they’re clinically compatible with active TB ; which may include chest x-ray changes
incl. idiopathic pleurisy with effusion , extra pulmonary TB ( incl. meningeal ,bone,
kidney, peripheral lymph nodes) or post mortem evidence of active TB)
Population estimates from the on-reserve communities were obtained from CWIS
(communities workload increase system) which categorized isolation types restricting
access to health care:
o“remote isolated” – no scheduled flights/ minimal telephone and radio, no road
access
o“isolated”- flights/ good telephone service/ no road access
o“semi-isolated”- flights/ good telephone service/( travelling distance) road access
>90km to physician services
o“non-isolated”- flights/good telephone service, road access <90km to physician
services
Results indicated that average housing density appeared to be higher in the First Nations
population that non-Aboriginal populations
