Resumo
The study objective was to evaluate the feasibility
of interviews by cell phone as a complement to
interviews by landline to estimate risk and protection
factors for chronic non-communicable
diseases. Adult cell phone users were evaluated
by random digit dialing. Questions asked were:
age, sex, education, race, marital status, ownership
of landline and cell phones, health condition,
weight and height, medical diagnosis of
hypertension and diabetes, physical activity, diet,
binge drinking and smoking. The estimates were
calculated using post-stratification weights. The
cell phone interview system showed a reduced
capacity to reach elderly and low educated populations.
The estimates of the risk and protection
factors for chronic non-communicable diseases
in cell phone interviews were equal to the estimates
obtained by landline phone. Eligibility,
success and refusal rates using the cell phone system
were lower than those of the landline system,
but loss and cost were much higher, suggesting it
is unsatisfactory as a complementary method in
such a context.
