Methods A survey was conducted in adolescent. The cluster sampling was used. The subjects were required to fulfill the self-report questionnaires and also received physical examinations by doctors. Results A total of 8 113 individuals were included in eczema studis, in whom eczema were present in 810 with a morbidity of eczema of 10.0% (9.3% after standardized). The prevalence rate of eczema in males and females were 8.1% and 11.2%, respectively (Plt;0.01). The prevalence rate of eczema in urban area was the same as that in rural area (10.0%). A total of 8 113 people were included in the urticaria study, in whom urticaria were found in 513. The prevalence rate was 6.3% (6.5% after standardized). The prevalence rate of urticaria in males and females were 4.5% and 7.6%, respectively (Plt;0.01), and were 6.9% and 4.9% respectively in rural area and urban area (Plt;0.01). A total of 7 977 people were included in AR studis. AR was present in 741 people, and the prevalence rate of AR was 9.3% (9.1% after standardized). The prevalence rate of AR in males and females were 9.4% and 9.2% respectively (Pgt;0.05), and were 10.1% and 9.0% respectively in urban area and rural area (Pgt;0.05). A total of 7 741 people were included in BA study, and BA were present in 296 people. The prevalence rate of BA were 3.8% (4.0% after standardized). The prevalence rate in males and females were 3.2% and 4.2% respectively (Plt;0.05), and were 2.9% and 4.1% respectively in urban area and rural area (Plt;0.05). Conclusion The prevalence rate of these commom allergic diseases in adolescent of Liangshan district was obtained. The females have a higher prevalence rate of eczema, urticaria and BA than that in the males; the prevalence rate of AR in males is similar to which in the females. A higher prevalence rate of eczema, urticaria and BA is found in rural area than that in urban area; the prevalence rate of AR in urban area is similar to which in rural area.
Objective To analyze the measles epidemic characteristic, so as to provide scientific evidence for the strategy of controlling and eliminating measles. Methods The data of measles cases was collected from the national epidemiological investigation and surveillance report system, and the measles epidemiological characteristic as well as the efficacy of measles control strategy were analyzed through descriptive studies. Results The total number of the reported measles cases reached 309 in 2009, the incidence rate was 5.1 per 100 000 population and declined by 71.26% compared with the year of 2008. Seasonal peak in 2009 appeared from January to April. The infants less than eight months old as well as the patients more than 15 years old were the main suffering population, which accounted for 33.98% (105/309) and 49.51% (153/309) of the total, respectively. The patients having no or having unclear measles vaccination history accounted for 93.2% (288/309). The cases of floating population accounted for 9.71% (30/309). Conclusion It has been demonstrated that vaccine immunization activities are important measures to eliminate measles. To achieve the goal of measles elimination, not only does the children routine immunization have to be performed, but also the strengthened immunization has to be carried out for the key crowd in key areas.
