为了解婴儿一岁期间的被动吸烟状况,为制定预防婴儿被动吸烟的措施提供依据,作者进行了此次研究。研究对象为美国北卡罗来纳州中部阿拉曼采和查塔姆县1986年4月至1987年5月出生的152名健康婴儿。分别在婴儿出生后的9～51天(平均18±7)和11.5～14.9个月(平均12.3±0.6个月)随访2次。在每次随访时除向婴儿的母亲了解婴儿暴露环境中家庭成员及非家庭成员的吸烟状况外,还用尿液袋采集婴儿的尿液样品,经冷冻后运至纽约州国家卫生基金会
To understand the status of passive smoking among infants during the first year of life, this study was conducted to provide a basis for the development of measures to prevent passive smoking in infants. The study population was 152 healthy infants born from April 1986 to May 1987 in Alamandong and Chatham County in central North Carolina. The patients were followed up twice (9-18 days) and 11.5-14.9 months (12.3 ± 0.6 months on average) respectively after birth. At each visit, in addition to informing the infant’s mother of the smoking status of family members and non-family members in the infant exposure environment, a urine bag was also used to collect urine samples from the baby, frozen and shipped to the New York State Sanitation Foundation
