To assess log-on rates and change in mediating variables achieved from a web-based nutrition intervention for African American families.
A parent and 9- to 12- year-old daughter (n=67 families) completed questionnaires measuring dietary change mediating variables.
Overall log-on rate was 59%. Significant positive changes were noted in mother-reported menu planning, self-efficacy, fruit/vegetable availability self-efficacy, modifying meat-fat practices, substitution fat practices, and healthy restaurant selection, and daughter-reported parent modeling of eating fruit and vegetables.
An Internet-delivered nutrition intervention for families was successful in achieving change in some mediating variables, with modest log-on rates. Future research should investigate impact on dietary behaviors.
评估针对非裔美国家庭的基于网络的营养干预措施的登录率以及中介变量的变化情况。
一位家长和9至12岁的女儿（共67个家庭）完成了测量饮食变化中介变量的问卷调查。
总体登录率为59%。在母亲报告的菜单规划、自我效能感、水果/蔬菜可得性自我效能感、改变肉类脂肪摄入习惯、替代脂肪摄入习惯以及健康餐厅选择方面，以及女儿报告的父母食用水果和蔬菜行为示范方面，均发现了显著的积极变化。
一项针对家庭的互联网营养干预措施成功地使一些中介变量发生了变化，登录率适中。未来的研究应调查其对饮食行为的影响。
