目的掌握疫苗观察对象的生活水平、消费行为、居住环境等社会经济活动情况 ,为正确评价疫苗效果提供科学依据。方法采用国际疫苗研究所统一制订的调查表 ,上门逐户调查研究人群39050户共135737人 ,用统计学方法分析观察人群的生活水平、消费行为、居住环境等社会经济活动的差异性。结果在当地居住5年以上的户口占82.4 % ;家庭主要职业 ,城市以上班族为多 ,占35.2% ,农村以农民为主 ,占56.9 % ;家庭每月平均收入城市为1338元、农村为794元。城市家庭每月平均支出为896元、农村为481元 ,其中食品支出占总收入的43% ,其次为房租 ;住房情况城市优于农村 ,城市有80%的家庭拥有3间以上住房 ,而农村只有50% ;城市家庭拥有私人住房的占74.4 % ,农村占69.5 % ;城市主要以私人汽车及摩托车作为交通工具 ,而农村则为自行车 ;城市家庭以电视机、沙发、电冰箱、自行车为四大件 ,电视机、自行车为农村的两大件。结论疫苗观察人群的平均生活水平远远低于全国平均生活水平 ,属于恩格尔系数划分的低层次小康标准。对于科学实施疫苗效果的观察来说 ,仍不失为一个条件适宜 ,生活水平、消费行为、生活环境相对平衡的自然群体 ,上述调查内容也是一项科学研究必不可少的本底调查。
Objective To grasp the socio-economic activities of the observed objects, such as living standards, consumption behavior and living environment, and provide a scientific basis for the correct evaluation of vaccine efficacy. Methods A questionnaire unifiedly formulated by the International Vaccine Institute was used. There were totally 130,737 people from 390 households with household-to-house investigation and study. The differences in socio-economic activities such as living standard, consumption behavior and living environment were observed and analyzed by using statistical methods. As a result, 82.4% of households have lived in the area for more than five years. Main occupations in the family occupy 35.2% of the total workforce in urban areas, with peasants in rural areas accounting for 56.9%. The average monthly household income is 1338 yuan in rural areas, 794 yuan. The monthly average expenditure of urban households was 896 yuan and that of rural areas was 481 yuan, of which food expenses accounted for 43% of the total income, followed by rent; the housing situation in urban areas was better than that in rural areas, and 80% of urban households had more than 3 houses, while rural areas Only 50% of urban households own 74.4% of private houses and 69.5% of rural residents. The cities mainly use private cars and motorcycles as their vehicles and rural areas as bicycles. The urban families use TV sets, sofas, refrigerators and bicycles as Four large pieces, television sets, bicycles for the rural two pieces. Conclusion The average living standard of the vaccine observation population is far below the national average living standard, which belongs to the low-level well-to-do standard of dividing the Engel’s coefficient. For the scientific implementation of the vaccine effect observation, it is still a natural conditions suitable conditions, living standards, consumer behavior, living environment is relatively balanced, the survey is also an essential background investigation of scientific research.
