African American adolescents are at risk of living in obesogenic environments, which may contribute to low-quality dietary intake and associated obesity risk. Family mealtime builds capacity for health behaviors; however, limited studies have assessed facilitators or barriers of family mealtime using an ecological approach among African American families. This study longitudinally (baseline, 8 weeks, 16 weeks) evaluated a range of ecological factors as predictors of family mealtime frequency and quality among 151 overweight African American adolescent-parent dyads (adolescent Mage = 12.9 ± 1.7; MBMI%=96.3 ± 4.4; %female = 60.9% [adolescent], 96.0% [parent]) that participated in the Families Improving Together (FIT) for Weight Loss trial. Multilevel model analyses demonstrated a significant two-way interaction between perceived neighborhood healthy food access and time (B = 0.11, SE = 0.05, p = 0.025), such that greater perception of neighborhood access to healthy foods was associated with increased family mealtime quality over time. Further, a significant two-way interaction between family social support for healthy eating and time (B = 0.13, SE = 0.06, p = 0.018), such that higher levels of reported social support were associated with increased family mealtime quality over time. Finally, a marginal two-way interaction between parental limit-setting on health behaviors and time (B = 0.19, SE = 0.10, p = 0.069), such that greater limit-setting was associated with increased family mealtime frequency over time. These findings indicate the importance of environmental and interpersonal support in supporting family mealtime frequency and quality in African American families.

非裔美国青少年面临生活在致胖环境中的风险，这可能导致低质量的饮食摄入以及相关的肥胖风险。家庭用餐时间有助于培养健康行为；然而，使用生态方法评估非裔美国家庭中家庭用餐时间的促进因素或障碍的研究有限。本研究纵向（基线、8周、16周）评估了一系列生态因素，作为151对超重的非裔美国青少年-父母二元组（青少年平均年龄Mage = 12.9 ± 1.7；平均身体质量指数百分比MBMI%=96.3 ± 4.4；女性比例%=60.9%[青少年]，96.0%[父母]）家庭用餐频率和质量的预测因素，这些二元组参与了“家庭共同改善（FIT）”减肥试验。多层次模型分析表明，邻里健康食品可及性感知与时间之间存在显著的双向交互作用（B = 0.11，标准误SE = 0.05，p = 0.025），即随着时间推移，对邻里健康食品可及性的更高感知与家庭用餐质量的提高相关。此外，家庭对健康饮食的社会支持与时间之间存在显著的双向交互作用（B = 0.13，标准误SE = 0.06，p = 0.018），即随着时间推移，报告的社会支持水平越高与家庭用餐质量的提高相关。最后，父母对健康行为的限制设定与时间之间存在边缘双向交互作用（B = 0.19，标准误SE = 0.10，p = 0.069），即随着时间推移，更多的限制设定与家庭用餐频率的增加相关。这些发现表明环境和人际支持在支持非裔美国家庭家庭用餐频率和质量方面的重要性。试验注册ClinicalTrials.gov # NCT01796067。该试验于2013年2月21日注册，第一名参与者于2013年7月12日入组。
