Abstract：
BACKGROUND: Food insecurity is a heightened concern among economically disadvantaged youth, and it may contribute to the atypical body mass index (BMI) patterns frequently observed in this group. Self-efficacy seems to intervene in the negative impacts of contextual restraints. This study investigated the relationship between food insecurity, self-efficacy, and BMI trajectory among economically disadvantaged Taiwanese youth.
METHODS: We utilized three-wave longitudinal data from the Taiwan Database of Children and Youth in Poverty. The Food Insecurity Score (FIS) assessed food insecurity with a 4-item scale measuring reduced meal frequency, hunger, skipping meals, and economic constraints. Moreover, the General Self-Efficacy Scale (GSES) assessed self-efficacy, showcasing the ability to handle stress effectively and envision success scenarios, contributing to positive outcomes. By employing latent growth modeling, we were able to delineate the impacts of baseline food insecurity and self-efficacy on initial BMI and its subsequent growth trajectory.
RESULTS: Elevated baseline FIS significantly predicted higher initial BMI (coefficient = 0.420, p = 0.042). Baseline GSES was negatively associated with initial BMI (coefficient = -0.093, p < 0.001) but positively predicted the BMI growth rate (coefficient = 0.023, p = 0.011).
CONCLUSIONS: Enhancing self-efficacy may be an effective multidisciplinary intervention to address psychosocial and socioeconomic factors when tackling weight problems in vulnerable youth groups.

摘要：
背景：粮食不安全是经济弱势青年的高度关注，它可能有助于该组中经常观察到的非典型体重指数（BMI）模式。自我效能感似乎干预了情境约束的负面影响。这项研究调查了粮食不安全之间的关系，自我效能感,经济弱势台湾青年的BMI轨迹。
方法：我们利用了台湾贫困儿童和青少年数据库的三波纵向数据。食物不安全评分（FIS）用4项量表评估食物不安全，测量减少的用餐频率，饥饿,不吃饭,和经济约束。此外，一般自我效能感量表(GSES)评估自我效能感，展示有效处理压力和设想成功场景的能力，有助于取得积极成果。通过采用潜在增长模型，我们能够描述基线食物不安全和自我效能对初始BMI及其随后的增长轨迹的影响.
结果：基线FIS升高显著预测初始BMI升高（系数=0.420，p=0.042）。基线GSES与初始BMI呈负相关（系数=-0.093，p<0.001），但对BMI增长率呈正相关（系数=0.023，p=0.011）。
结论：增强自我效能感可能是解决弱势青年群体体重问题时解决心理社会和社会经济因素的有效多学科干预措施。
