Allergies in Asia Pacific:

A Landmark Survey of Nasal Allergy Sufferers in China

Allergies in Asia Pacific describes the symptoms, impact, and treatment of nasal allergies in China. In total, 19,580 households across the country were screened for adults, children and adolescents with a diagnosis of nasal allergies or allergic rhinitis, symptoms or treatment for nasal allergies in the past 12 months. The sample was probability-based to ensure valid statistical inference to the population. The procedures used were based on standard protocols that allow robust estimation of outcomes and characteristics.

The target population for this study was adults or children and adolescents diagnosed with nasal allergies or allergic rhinitis, symptomatic or being treated for nasal allergies in the past 12 months. A total of 325 interviews were completed. The field work was conducted between December 7, 2009 and January 15, 2010. The sampling frame included 10 cities across China. The cities and their surrounding areas included Shanghai, Beijing, Guangzhou, Wuhan, Dalian, Kunming, Chengdu, Lanzhou, Fuzhou and Handan. The sample size was distributed proportionately between these cities based on their population. The numbers were generated using RDD. If there was more than one eligible respondent in a household, the CATI program randomly selected one for the interview. The responses were entered into a CATI program that used range checks and directed skip patterns. The average interview length was 34.9 minutes. This study was developed and conducted by Abt SRBI, an international survey research organization. The survey sponsor was Nycomed, a research-based pharmaceutical company.
