The effect of instructional models on the changing behavior of consuming fruit and vegetables in the prevention of diseases caused by consumption of foods including rice, contaminated with toxic metals, has not been investigated in Iran yet.
To compare an Ecological-social model (ECO) group and Control group in increasing fruit and vegetable consumption.
This research involved implementation of a six-month randomized controlled educational interventionist program into a group of Ecological-social framework along with a control group, totally summing up to 160 women between 18 and 50 years of age in Ilam, Iran in 2014. The questionnaire included knowledge, social support construct (immediate family, relatives, friends, colleagues and neighbors.) and fruit and vegetable intake in both groups before and after the intervention was examined. Data were analyzed by SPSS version 16 using the signed ranks test, and repeated measures analysis of variance analysis, and confidence interval of 95% were employed.
The results of the signed ranks test showed a significant increase in social support in the intervention group (p<0.001). This test showed a significant increase in fruit and vegetable consumption and a significant increase in the number of women using healthy rice (p<0.001), and a significant reduction in the number of women consuming unhealthy rice in the intervention group (p<0.001), that determines dietary intake improvement after the intervention compared with before the intervention (p<0.01). However, this improvement was not observed in the control group.
The results showed that ECO plays an effective role in improving fruit and vegetable consumption in women. Therefore, this model was implemented as a health protocol through health-care centers to conduct the prevention of complications resulting from the use of food contaminated with toxic metals.
在伊朗，尚未对教学模式在改变水果和蔬菜消费行为以预防因食用包括受有毒金属污染的大米在内的食物所引发疾病方面的效果进行研究。
比较生态社会模式（ECO）组和对照组在增加水果和蔬菜消费量方面的差异。
本研究于2014年在伊朗伊拉姆对一组处于生态社会框架下的人群以及一个对照组实施了为期六个月的随机对照教育干预项目，共有160名年龄在18至50岁之间的女性参与。对两组干预前后的问卷进行了检查，问卷内容包括知识、社会支持结构（直系亲属、亲戚、朋友、同事和邻居）以及水果和蔬菜摄入量。使用SPSS 16版软件，通过符号秩检验、重复测量方差分析以及95%置信区间对数据进行分析。
符号秩检验结果显示，干预组的社会支持显著增加（p<0.001）。该检验表明，干预组的水果和蔬菜消费量显著增加，食用健康大米的女性数量显著增加（p<0.001），而食用不健康大米的女性数量显著减少（p<0.001），这表明与干预前相比，干预后饮食摄入量有所改善（p<0.01）。然而，对照组未观察到这种改善。
结果表明，生态社会模式在改善女性水果和蔬菜消费方面发挥了有效作用。因此，该模式作为一项健康方案通过医疗保健中心实施，以预防因食用受有毒金属污染的食物而导致的并发症。
