The childrens environment survey 2011

The Children's Environmental Health Survey is carried out in collaboration between the Institute of Environmental Medicine at Karolinska Institutet and the Statistics Sweden, on behalf of the Public Health Agency of Sweden. The questionnaire concerned the health and environments of children in three age groups: 8 months, 4 years, and the 12 years. The questions were in most cases answered by the children’s parents, but some of the questions were directly asked of children in 12-year-old group. The questions focused on the children’s exposure to environmental factors and on their self-rated symptoms, health, and levels of disturbance by various environmental factors. Statistics Sweden supplemented the data from the survey with demographic data from various central registers including gender, age, place of residence, country 24 of birth, and parents’ educational level etc. Nearly 71 400 children were randomly selected within each county. Approximately 36 000 people responded to the survey, representing a response rate of over 50 percent. In addition to the study in 2011 a previously survey had been conducted in 2003, making it possible to compare the results and show how children’s environment and health changed during the eight years between the surveys. Purpose: The aim was to chart how environmental factors like air pollution, noise and indoor environment effects the health of children and adolescents.儿童环境健康调查（Children's Environmental Health Survey）由卡罗林斯卡学院环境医学研究所与瑞典统计局合作开展，受瑞典公共卫生署委托执行。 本次问卷针对8月龄、4岁及12岁三个年龄段儿童的健康与环境状况设计，多数问题由儿童父母代为作答，但部分问题直接向12岁组儿童进行询问。 调查内容聚焦儿童暴露于各类环境因素的情况，以及他们的自我报告症状、健康状态和受各类环境因素干扰的程度。瑞典统计局通过多项中央登记系统补充了调查数据，包括性别、年龄、居住地、出生国及父母受教育水平等人口统计学信息。每个郡内随机选取近71400名儿童，最终约36000人参与作答，应答率超过50%。 除2011年开展的本次调查外，团队还于2003年完成过一项前期调查，由此可对比两次调查结果，呈现八年间儿童环境与健康状况的变化趋势。 研究目的：明确空气污染、噪声及室内环境等环境因素对儿童与青少年健康的影响。
