Studies have shown that obesity (OB) has strong intergenerational linkages and tends to cluster in families, but there is a dearth of research examining the socioecological factors predictive of weight status concordance and discordance among parents and adolescents. We ran a stepwise multinomial logistic regression to assess for sociodemographic, individual-, and family-level predictors of four dyadic weight status groups using data from 1516 parent/adolescent dyads from the National Cancer Institute's Family Life, Activity, Sun, Health, and Eating Study. We categorized parent/adolescent dyads into one of four groups based on their BMI: (1) Healthy Weight Concordance (, both parent and adolescent in the normal weight range); (2) overweight (OW)/OB Concordance (, both parent and adolescent with OW or OB); (3) Discordance-Parent OW/OB (, parent with OW/OB and adolescent in the normal weight range); or (4) Discordance-Adolescent OW/OB (, adolescent with OW/OB and parent in the normal weight range). There were 475 parent/adolescent dyads (31.3%) in the Healthy Weight Concordance group, 351 (23.2%) in the OW/OB Concordance group, 604 (39.8%) in the Discordance-Parent OW/OB group, and 86 (5.7%) in the Discordance-Adolescent OW/OB group. Being from a low socioeconomic family, identifying as a minority, and identifying as a male parent were associated with an OW/OB dyadic BMI. Higher levels of adolescent and parent emotional eating were significantly associated with parent/adolescent dyads being in the OW/OB Concordance group. Parent emotional eating was also associated with Discordance-Parent OW/OB. In contrast, parents' and adolescents' physical activity self-efficacy was associated with a Healthy Weight dyadic BMI vs. OW/OB Concordance or Discordance-Parent OW/OB. Our findings highlight the strength of OW/OB concordance in families, especially among lower socioeconomic and ethnic minority families and the significance of emotional eating and physical activity self-efficacy in contributing to BMI patterns among parents and adolescents.
研究表明，肥胖（OB）具有强烈的代际关联，并且往往在家庭中聚集，但对于预测父母和青少年体重状况一致性和不一致性的社会生态因素的研究却很少。我们使用来自国家癌症研究所家庭生活、活动、阳光、健康和饮食研究的 1516 对父母/青少年对的数据，进行逐步多项逻辑回归分析，以评估社会人口统计学、个体和家庭层面预测因素对四种对偶体重状况组的影响。我们根据 BMI 将父母/青少年对分为以下四组之一：（1）健康体重一致性（父母和青少年均处于正常体重范围）；（2）超重/肥胖一致性（父母和青少年均超重或肥胖）；（3）父母超重/肥胖不一致（父母超重/肥胖，青少年处于正常体重范围）；或（4）青少年超重/肥胖不一致（青少年超重/肥胖，父母处于正常体重范围）。在健康体重一致性组中有 475 对父母/青少年（31.3%），超重/肥胖一致性组中有 351 对（23.2%），父母超重/肥胖不一致组中有 604 对（39.8%），青少年超重/肥胖不一致组中有 86 对（5.7%）。来自低社会经济家庭、少数民族和男性父母与 OW/OB 对偶 BMI 相关。青少年和父母的情绪性进食水平较高与父母/青少年处于 OW/OB 一致性组显著相关。父母的情绪性进食也与父母超重/肥胖不一致相关。相比之下，父母和青少年的身体活动自我效能感与健康体重对偶 BMI 相关，而与 OW/OB 一致性或父母超重/肥胖不一致相关。我们的研究结果强调了 OW/OB 在家庭中的一致性，尤其是在社会经济地位较低和少数民族家庭中，以及情绪性进食和身体活动自我效能感在父母和青少年 BMI 模式中的重要性。
