To examine the associations among household food insecurity (FI), academic performance, and weight status in urban primary schoolchildren.
Cross-sectional study.
Primary schools in Tehran, Iran.
A total of 803 students (419 boys and 384 girls), aged 10-12 years, were recruited from 43 primary schools.
Levels of FI were measured using a locally validated, 18-item household food security survey module. Academic performance was assessed by 152 teachers through a specifically designed, 20-scale questionnaire. Standard anthropometric measurements were also taken.
Linear and multinomial regressions were conducted.
At the household level, FI was associated with poorer grades in all subjects studied (except for social science in FI without hunger) (P < .05). At the child level, a significant association was observed between low food security and poorer grades in all subjects studied, whereas for very low food security, this relationship was significant only for mathematics, reading, and science (P < .05). Food insecurity without hunger (odds ratio = 2.56; 95% confidence interval, 1.05-6.23) and low food security (odds ratio = 4.41; 95% confidence interval, 1.58-12.23) were associated with overweight only in girls.
The findings confirm the need for policies and programs to improve students' dietary quality and food security to improve their health as well as educational attainment. Future research is needed to explore further the association between food security and academic performance.
探讨城市小学生家庭食物不安全、学业成绩和体重状况之间的关系。
横断面研究。
伊朗德黑兰的小学。
共招募 43 所小学的 803 名 10-12 岁学生（男 419 名，女 384 名）。
采用经过当地验证的 18 项家庭食物安全调查模块来衡量家庭食物不安全的程度。学业成绩由 152 名教师通过专门设计的 20 分量表问卷进行评估。同时还进行了标准的人体测量。
进行线性和多项回归分析。
在家庭层面，所有研究学科的成绩均与粮食不安全（除了饥饿型粮食不安全与社会科学学科成绩无关）呈负相关（P<0.05）。在儿童层面，低粮食安全与所有研究学科的成绩较差显著相关，而极低粮食安全仅与数学、阅读和科学相关（P<0.05）。无饥饿型粮食不安全（比值比=2.56；95%置信区间，1.05-6.23）和低粮食安全（比值比=4.41；95%置信区间，1.58-12.23）仅与女生超重有关。
研究结果证实，需要制定政策和方案来改善学生的饮食质量和粮食安全，以提高他们的健康和教育水平。未来的研究需要进一步探讨粮食安全与学业成绩之间的关系。
