Background
Otitis media (OM) is a leading cause of health care visits and drugs prescription. Its complications and sequelae are important causes of preventable hearing loss, particularly in developing countries. Within the Global Burden of Diseases, Injuries, and Risk Factors Study, for the year 2005 we estimated the incidence of acute OM, chronic suppurative OM, and related hearing loss and mortality for all ages and the 21 WHO regional areas.

Parental smoking and the risk of middle ear disease in children: a systematic review and meta-analysis.

Risk factors associated with chronic otitis media (COM) and recurrent otitis media (ROM) have been investigated in previous studies. The objective of this study was to integrate the findings and determine the possible risk factors for COM/ROM based on our meta-analysis. A comprehensive search of electronic bibliographic databases (PubMed, Embase, CNKI and Wanfang database) from 1964 to Dec 2012, as well as a manual search of references of articles, was performed. A total of 2971 articles were searched, and 198 full-text articles were assessed for eligibility; 24 studies were eligible for this meta-analysis. Regarding risk factors for COM/ROM, there were two to nine different studies from which the odds ratios (ORs) could be pooled. The presence of allergy or atopy increased the risk of COM/ROM (OR, 1.36; 95% CI, 1.13-1.64; P = 0.001). An upper respiratory tract infection (URTI) significantly increased the risk of COM/ROM (OR, 6.59; 95% CI, 3.13-13.89; P<0.00001). Snoring appeared to be a significant risk factor for COM/ROM (OR, 1.96; 95% CI, 1.78-2.16; P<0.00001). A patient history of acute otitis media (AOM)/ROM increased the risk of COM/ROM (OR, 11.13; 95% CI, 1.06-116.44; P = 0.04). Passive smoke significantly increased the risk of COM/ROM (OR, 1.39; 95% CI, 1.02-1.89 P = 0.04). Low social status appeared to be a risk factor for COM/ROM (OR, 3.82; 95% CI, 1.11-13.15; P = 0.03). Our meta-analysis identified reliable conclusions that allergy/atopy, URTI, snoring, previous history of AOM/ROM, Second-hand smoke and low social status are important risk factors for COM/ROM. Other unidentified risk factors need to be identified in further studies with critical criteria.

Risk Factors for Chronic and Recurrent Otitis Media–A Meta-Analysis

Objectives:

Although racial/ethnic and socioeconomic disparities in child health are prevalent, little is known about them within common pediatric otolaryngic problems. Otitis media (OM) is a frequent diagnosis in children, and tympanostomy tube placement is the most common surgical treatment for OM. We sought to identify current knowledge regarding racial/ethnic and socioeconomic disparities in children with OM or tympanostomy tube placement.



Methods:

Qualitative systematic review of MEDLINE database for U.S.-based articles reporting on racial/ethnic or socioeconomic disparities in diagnosis or surgical treatment of OM over the last 30 years.



Results:

Of 428 abstracts identified, 15 met inclusion criteria. Articles addressed OM prevalence (12 of 15), risk factors (9 of 15), and tympanostomy tube insertion (4 of 15). Minority racial/ethnic groups studied were Black (11 of 15), Hispanic (6 of 15), American Indian/Alaska Native (2 of 15), and Asian (1 of 15). Predominant findings showed: 1) the most common identified risk factor for OM is socioeconomic status; 2) considerable variability exists concerning racial/ethnic disparities in disease prevalence; and 3) White children are more likely to undergo tympanostomy tube insertion compared to Black or Hispanic children.



Conclusions:

Racial/ethnic and socioeconomic disparities exist for the prevalence and treatment of children with OM. Socioeconomic deprivation increases the risk of OM in children. Despite the frequency of tympanostomy tube insertion in children in the United States, few studies have addressed inequalities in access or utilization of surgical therapy. Given the changing healthcare climate and the social and economic impact of OM in children, further investigation of racial/ethnic and socioeconomic disparities targeting access to surgical treatment of OM should take precedence in health services research.
