Otolaryngology, University of Minnesota School of Medicine; and the
Division of Biostatistics, University of Minnesota School of Public
Health, Minneapolis, Minnesota.
Objectives. To investigate maternal knowledge and attitudes about otitis media (OM) risk, to estimate the prevalence of risk factors in the first year of life, and to identify barriers to the reduction of risk factors (eg, formula feeding, day care attendance, and exposure to passive smoke).
Methods. Questionnaires mailed to a systematic sample of
504 Minnesota women
18 years old identified through 1994 birth
certificates.
Results. Eighty percent returned a completed survey.
According to maternal report, 29% of infants (age 8 to 13 months) had recurrent OM (
3 episodes) and 2% had tympanostomy tubes. Forty-six percent attended day care, 29% had
1 smoking parent, and 49% breastfed for
2 months. Women were more knowledgeable about OM signs
and symptoms than about risk factors. Mean OM knowledge score (the sum
of correct true-false responses) was 7.0 (standard deviation = 1.6). Using multiple linear regression, knowledge score was
significantly related to marital status, education, age, area of
residence, breastfeeding (months), and number of cigarettes smoked per
day by the mother, but not to infant or sibling OM history or day care
attendance (R = .23). Infant history of OM (odds ratio,
1.9; 95% confidence interval, 1.1 to 3.2) and white race (odds ratio,
0.3; 95% confidence interval, 0.1 to 0.8), but not the presence of
risk factors, were significantly related to having received
clinicians' advice about OM prevention advice.
Conclusion. OM education and prevention programs should target pregnant women and new mothers with OM risk factors, and those who are young, single, and less educated.
Key words: otitis media, knowledge, attitudes, passive smoking, day care, breastfeeding, health survey.
