Abstract：
BACKGROUND: Healthy eating habits are essential for improving nutritional status and strengthening immunity against infectious diseases. This study examined the relationship between diet quality and stunting in school-aged children in an infectious disease-endemic area of western Kenya.
METHODS: This cross-sectional study included 260 school-aged children (age 9-17 years) enrolled in primary schools in Mbita Sub-county, western Kenya. The nutritional status was assessed using anthropometric measurements. Dietary intake was measured using food frequency questionnaires and evaluated using the Food Pyramid (FP) score, which indicates adherence to the Kenyan food-based dietary guideline. Information on the children\'s age, sex, maternal education, and household wealth index was collected using a household-based questionnaire. Infections with the predominant parasites, such as Schistosoma (S.) mansoni, were detected via microscopy. The trend associations of the FP score with food group intake were examined to characterize the dietary intake of this population. Logistic regression analysis was performed to investigate the relationship between stunting and FP score tertiles, adjusted for sociodemographic and economic indicators and parasitic infection status.
RESULTS: Among the studied schoolchildren, 15.0% exhibited stunting, while 76.2% were infected with S. mansoni. The mean FP score was 25.6 out of 50 points. A higher FP score was characterized by a high intake of roots and tubers, dairy products, pulses, and fruits and a low intake of cereals and animal-source foods. The analysis revealed a trend: a lower risk of stunting was evident in groups with elevated FP scores (p for trend = 0.065). However, these trend associations were observable among subjects with either negative or light S. mansoni infection (p for trend = 0.016).
CONCLUSIONS: A higher quality diet, as evaluated by FP scores, was associated with a low risk of stunting among school-aged children. Notably, this association seemed to weaken in the presence of a high burden of S. mansoni infection. It highlights the importance of enhancing dietary quality through the promotion of diverse nutrient-dense foods alongside effective S. mansoni infection control for improved growth. This study contributes fundamental knowledge for understanding the diet-malnutrition relationship in areas endemic for S. mansoni infection.

摘要：
背景：健康的饮食习惯对于改善营养状况和增强对传染病的免疫力至关重要。这项研究调查了肯尼亚西部传染病流行地区学龄儿童的饮食质量与发育迟缓之间的关系。
方法：这项横断面研究包括在Mbita县小学就读的260名学龄儿童（9-17岁），肯尼亚西部。使用人体测量法评估营养状况。使用食物频率问卷测量饮食摄入量，并使用食物金字塔（FP）评分进行评估，这表明符合肯尼亚基于食物的饮食指南。关于儿童年龄的信息，性别,母亲教育,家庭财富指数是使用基于家庭的问卷收集的。主要寄生虫感染，如血吸虫(S.)Mansoni,通过显微镜检测。检查了FP评分与食物组摄入量的趋势关联，以表征该人群的饮食摄入量。进行Logistic回归分析以探讨发育迟缓与FP评分的关系。根据社会人口和经济指标以及寄生虫感染状况进行了调整。
结果：在被研究的学童中，15.0%表现出发育迟缓，而76.2%的人感染曼氏链球菌。50分中的平均FP评分为25.6分。较高的FP评分的特征是根和块茎的高摄入量，乳制品,脉冲,和水果以及谷物和动物源食物的低摄入量。分析揭示了一种趋势：在FP评分升高的组中，发育迟缓的风险较低（趋势p=0.065）。然而,在曼氏链球菌阴性或轻度感染的受试者中可以观察到这些趋势关联(趋势p=0.016).
结论：高质量的饮食，根据FP分数评估，与学龄儿童发育迟缓的低风险有关。值得注意的是,在曼氏链球菌感染高负担的情况下,这种关联似乎减弱.它强调了通过促进多种营养丰富的食物以及有效的曼氏链球菌感染控制以改善生长来提高饮食质量的重要性。这项研究为了解曼氏球菌感染流行地区的饮食与营养不良关系提供了基本知识。
