这项研究提供了当女性和她们的孩子处于生命周期的相似阶段时，她们之间身体质量指数(BMI)代际持久性的估计。使用1979年全国青年纵向调查(NLSY79)和NLSY79青年成人调查的数据，当女性和她们的孩子年龄在16岁到24岁之间时，测量她们体重状况之间的关联。在整个样本中，测量的BMI代际相关性明显不同于零，等于0.35。这一结果因性别不同而不同，女孩和他们的母亲之间的BMI相关性为0.38，而母亲和他们的儿子之间的BMI相关性明显较低，为0.32。使用分位数回归和象限相关技术对BMI分布的这种关系进行测量表明，BMI水平较高时，BMI的代际持久性最强。当实施肥胖和超重的绝对结果时，会发现几代人之间存在强烈的依赖性。这些结果证明，体重问题在几代人中持续存在，这可能会影响家庭内部的经济流动性。
This research provides estimates of the intergenerational persistence of Body Mass Index (BMI) between women and their children when both are at similar stages of the lifecycle. Using data from the National Longitudinal Survey of Youth 1979 (NLSY79) and the Young Adults of the NLSY79, associations between the weight status of women and their children are measured when both generations are between the ages of 16 and 24. In the entire sample, the measured intergenerational correlation of BMI is significantly different from zero and equal to 0.35. This result differs by gender with a BMI correlation between female children and their mothers of 0.38, compared to a significantly lower BMI correlation of 0.32 between mothers and their sons. Measures of this relationship across the distribution of BMI using quantile regression and quadrant dependence techniques indicate that the intergenerational persistence of BMI is strongest at higher levels of BMI. Strong dependence across generations is found when categorical outcomes of obesity and overweight are implemented. These results provide evidence of the strong persistence of weight problems across generations which may affect economic mobility within families.
