中英文简介
肥胖正成为威胁中国老年人健康的重要风险性因素。尽管众多研究认为，较高受教育程度的子女能够从多维度改善和提高老年父母的健康水平，但尚未发现关注子女受教育程度是否影响老年父母肥胖风险的文献。本文试图研究子女受教育程度对老年父母肥胖风险的影响，分析年龄和出生队列因素的调节效应。
本文利用中国健康与营养调查1993-2015年纵向追踪数据，具体考察了同住成年子女受教育程度对1956年以前出生老年人BMI、超重风险、腰围和中心型肥胖风险的影响。研究发现，在控制其他混杂因素后，子女受教育程度对老年男性BMI和超重风险具有倒U模式影响，对老年女性呈积极影响；子女教育与老年男性和女性腰围的影响也呈现倒U模式，但并不显著影响老年人中心型肥胖风险。进一步对调节效应的分析显示，子女教育对老年父母肥胖风险的影响存在年龄和出生队列差异。子女受教育程度越高，较早出生队列老年人的肥胖风险越高；但在较晚出生队列中，子女教育的影响效应发生“逆转”，即子女受教育程度高的老年人的肥胖风险较低，且其与子女受教育程度低的老年人的肥胖风险差异随年龄增长持续扩大；这种逆转现象在女性中尤为明显。研究结果表明，在连续出生队列中，子女教育正逐渐演变为中国老年人肥胖的保护性因素。
The study focuses on the role of adult offspring's educational attainment in obesity among older adults in China and investigates age and birth cohort heterogeneities in the educational effect. Using the longitudinal data from the 1993–2015 China Health and Nutrition Survey (CHNS), we employed three-level mixed-effects models and conducted sex-stratified analyses to examine the effects of co-resident offspring's education on body mass index (BMI), overweight, waist circumference (WC), and abdominal obesity among older people born before 1956. After controlling for confounding factors, the overall results showed inverted U-shaped educational gradients in BMI-based outcomes for males and positive gradients for females. The effect of education on WC exhibited an inverted U-shaped pattern for both sexes, but no significant effect on abdominal obesity was found among the overall population. However, further analyses of interaction effects indicated considerable age and cohort variations in the educational effects on obesity outcomes. Offspring's schooling was positively associated with obesity among earlier birth cohorts; Among more recent birth cohorts, especially among females, the educational effects were reversed, and disparities in obesity outcomes across education categories strengthened with age. These findings imply that offspring's education appears to gradually exert a protective role against obesity among Chinese older adults in successive cohorts.
