【摘要】 目的 探讨我国低收入家庭体重代际传递的影响因素，为阻断健康纵向不平等提供政策依据。方法 基于最新中国家庭追踪调查(CFPS)2022年数据，进行MLOGIT模型分析。结果 母亲体重状况对子代体重的影响显著：其偏瘦使子代偏瘦风险增加56.7%(OR=1.567,P<0.05),子代肥胖风险降低41.9%(OR=0.581,P<0.05);其肥胖使子代肥胖风险增加55.5%(OR=1.555,P<0.05)。父亲体重状况对子代影响有限：其肥胖对子代肥胖无显著影响。男性子代、低龄更易超重或肥胖。父母受教育程度提高显著降低子代肥胖风险，农业户籍母亲可能同时关联着子代较低的偏瘦风险和更高的超重肥胖风险。结论 低收入家庭中父代体重水平与子代体重水平具有较强的相关性，在低收入家庭中，母亲是子代健康更全面且更直接的影响者，父亲的影响则相对有限。子代特征与家庭经济因素也是影响子代健康的重要因素。因此，打破低收入家庭体重劣势的代际传递需采取差异化策略。更多还原

【Abstract】 Objective To investigate the factors associated with intergenerational transmission of weight status in low-income families in China and to provide evidence for policies aimed at interrupting the vertical inequality in health. Methods Utilizing data from the 2022 China Family Panel Studies(CFPS), we employed Multinomial Logistic Regression Model(MLOGIT) models to analyze the associations. Results Maternal weight status showed significant effects on offspring weight. Compared to mothers with normal weight, underweight mothers were associated with a 56.7% higher risk of offspring being underweight(OR=1.567, P<0.05) and a 41.9% lower risk of offspring obesity(OR=0.581, P<0.05). Obese mothers were associated with a 55.5% increased risk of offspring obesity(OR=1.555, P<0.05). Paternal weight status had a limited influence on offspring weight outcomes, with no significant association observed between paternal obesity and offspring obesity. Male offspring and children of younger age exhibited a higher likelihood of being overweight or obese. Higher educational attainment of both parents was significantly associated with a reduced risk of offspring overweight or obesity. Furthermore, maternal rural residency was linked to a complex pattern, potentially associated with a decreased risk of offspring underweight yet an increased risk of obesity. Conclusion In low-income families, parental weight status is strongly correlated with offspring weight status. Mothers serve as more comprehensive and direct influencers on offspring health, whereas the influence of fathers is relatively limited. Offspring characteristics and household economic factors are also important determinants of offspring health. Therefore, breaking the intergenerational transmission of weight disadvantages in low-income families requires differentiated strategies.更多还原
