We used data from the National Longitudinal Survey of Youth (n = 6108; 50.9% males; 16.7% Black, 8.1% Hispanic, 75.2% Non-Black, Non-Hispanic) to examine associations between parental emotional support trajectories at 0–15 years and overweight or obesity at 15–19 years and explore the effects of timing and cumulative exposure to low parental emotional support on overweight or obesity. Parental emotional support was assessed using the Home Observation Measurement of the Environment and adolescent overweight or obesity was defined using the International Obesity Task Force cut-offs. Latent Class Analysis was used to identify parental emotional support trajectories and Poisson regression was used to examine associations under study. Low parental emotional support in childhood increased the risk of adolescent overweight or obesity, with gender-based differences.

父母的情感支持轨迹和青少年超重或肥胖的风险

我们使用了全国青年纵向调查的数据（n = 6108; 50.9% 男性；16.7% 黑人，8.1% 西班牙裔，75.2% 非黑人，非西班牙裔）来检查 0-15 岁时父母的情感支持轨迹与 15-19 岁时的超重或肥胖之间的关联，并探索时间和累积暴露于父母对超重或肥胖的情感支持不足。使用环境的家庭观察测量评估父母的情感支持，使用国际肥胖特别工作组的临界值定义青少年超重或肥胖。潜在类别分析用于识别父母的情感支持轨迹，泊松回归用于检查研究中的关联。童年时期父母情感支持不足会增加青少年超重或肥胖的风险，并存在性别差异。
