项目摘要

Background : It is well-known that the offspring from mother who smoked during pregnancy become to be obese in the future. However, whether this risk factor is independent of other confounding factors remains unknown. In this study, the cross-sectional assessment of relationship between maternal smoking during pregnancy and body composition of offspring who examined both life style and passive smoking screening tests.Methods : One thousand-three hundred and sixty-six elementary school children (male : female ratio 1.1:1.0, aged from 9 to 10 years old) of grade 4 were enrolled into this study. All children had both life style and passive smoking tests. Urinary cotinine measurement and items of life style screening test (body weight, body length, body mass index (BMI), obesity index (OI), blood test of liver function and lipid profile, questionnaires of maternal smoking and life style) were evaluated in terms of the relation with maternal smoking. In addition, urinary 8-hydroxydeoxyguano … More sine (8-OHdG) concentration was measured in 80 children selected at random to assess the relation with oxidative stress.Results : Both BMI and OI were significantly increased in children with mother who smoked during pregnancy compared to children with the mother who never smoked (BMI : 17.2±2.7kg/m2 vs 16.9±2.5kg/m2, p=0.016、OI : 2.7±14.3% vs 0.4±14.0% , p=0.003). The degree of increment was positively correlated with the periods of maternal smoking. And the increments of BMI and OI were resulted from increased body weight and shortened height. In the confounding factors, "breakfast with family", "watching television at dinner", "eat and drink before sleep", "television watching more than 2 hours", "sleep duration less than 8 hours" and "play sports" were statistically significant. BMI and OI were significantly increased in children with maternal smoking during pregnancy in every confounding factor. On the other hand, urinary 8-OHdG concentration was negatively correlated with the BMI in children who had more than 1.3 ng/ml of urinary cotinine, and therefore, may be related with the basal metabolism.Conclusion : Maternal smoking is a risk factor of increasing BMI and OI when children whose mother smoked during pregnancy become to 9 to 10 years old, and may be independent of other confounding factors. Therefore, all of young females who reach to age of pregnancy should not smoke. Less

背景：众所周知，母亲在怀孕期间吸烟的后代将来会变得肥胖。然而，这种危险因素是否独立于其他混杂因素仍然未知。本研究采用生活方式和被动吸烟筛查相结合的方法，对1366名小学四年级儿童（男女比例1.1：1.0，年龄9 ~ 10岁）进行了母亲孕期吸烟与子代体成分关系的横断面研究。所有儿童都进行了生活方式和被动吸烟测试。通过尿可替宁测定、生活方式筛查项目（体重、身长、体重指数（BMI）、肥胖指数（OI）、肝功能和血脂检查、母亲吸烟情况和生活方式问卷）评价与母亲吸烟的关系。此外，尿中8-羟基脱氧鸟粪 ...更多信息结果：母亲孕期吸烟的儿童的BMI和OI均显著高于母亲不吸烟的儿童（BMI：17.2±2.7kg/m2 vs 16.9±2.5kg/m2，p= 0.016，OI：2.7± 14.3%vs 0.4±14.0%，p=0.003）。增加的程度与母亲吸烟的时间呈正相关。BMI和OI的增加是由于体重增加和身高缩短所致。在混杂因素中，“与家人共进早餐”、“晚餐时看电视”、“睡前吃喝”、“看电视2小时以上”、“睡眠时间少于8小时”和“运动”有统计学意义。在各混杂因素中，母亲孕期吸烟的儿童BMI和OI均显著升高。另一方面，尿8-OHdG浓度与BMI呈负相关的儿童有超过1.3 ng/ml的尿可替宁，因此，可能与基础metabolic.Conclusion：母亲吸烟是一个危险因素，增加BMI和OI时，母亲在怀孕期间吸烟的儿童成为9至10岁，可能是独立的其他混杂因素。因此，所有达到怀孕年龄的年轻女性都不应该吸烟。少
