Self-ear-cleaning among educated young adults in Nigeria.

Context: Self-ear-cleaning has been reported to be common from several hospital-based studies and it has been associated with some diseases of the ear.

Aims: To determine community-based prevalence of self-ear-cleaning and its sociodemographic correlates among educated young adults in Nigeria.

Settings And Design: A cross-sectional survey conducted in a National Youth Service Corps camp in Nigeria.

Subjects And Methods: Semistructured questionnaires were administered on a randomly selected sample of 1280 respondents. The outcome variable was self-ear-cleaning. Independent variables were sociodemographic variables, materials used and ear-cleaning habits.

Statistical Analysis Used: Statistical Package for the Social Sciences (SPSS) version 15 was utilized for univariate, bivariate, and multiple logistic regression analysis.

Results: There were 1012 respondents (M: F = 1.05:1). Mean age was 25.3 (standard deviation, 2.34). Prevalence of self-ear-cleaning was 93.4%. Mean age at first cleaning was 7.6 years. Cotton buds were the most frequently used objects (in 85.1%). Prevalence was high irrespective of sociodemographic class, significantly higher among females (χ(2) = 4.549, P = 0.033), those who believed the habit was beneficial (χ(2) = 114.185, P < 0.001) and those whose parents and siblings practiced the habit. Significant predictive factors were self-ear-cleaning in respondent's father [odds ratio (OR) P = 0.011) and owning cotton buds (OR = 0.192, P = 0.007).

Conclusions: Self-ear-cleaning is almost universal. Most of the population is, therefore, at risk of possible harmful effects. Also, medical advice against self-ear-cleaning is not widely known. Rather, the erroneous perception that self-ear-cleaning is beneficial is common. Collaborative health education efforts targeted at families and schools and campaigns and advocacy for legislation regulating the sale of cotton buds are recommended.
