Here we analyzed the relationship of the food insecurity with overweight and food consumption in schoolchildren of Mexico City.
Sample (n=768) students of six primary schools of Mexico City. Socioeconomic status and food insecurity were evaluated by means of a questionnaire. According to food security-insecurity, the students were categorized in three groups (food secure, moderate food insecure and severe food insecure). Food consumption frequency was evaluated with a questionnaire. It was considered that students were overweight when their Z score values of body mass index (BMI) to age was greater than +2 standard deviations, according to CDC reference.
The highest rate of overweight was observed in children with severe food insecurity (15.8%), followed by children with moderate food insecurity (10.4%), and by food secure children (6.9%). The same pattern was observed after adjusting by age, sex and socioeconomic status. The students with food insecurity had greater consumption of fatty cereals, salty foods and high energy density sweets.
In schoolchildren, food insecurity is related to greater risk of overweight, possibly because the more food insecure households acquire more low cost and high energy density foods.
在此我们分析了墨西哥城学童粮食不安全状况与超重及食物消费之间的关系。
样本为墨西哥城六所小学的768名学生。通过问卷评估社会经济状况和粮食不安全状况。根据粮食安全 - 不安全程度，学生被分为三组（粮食安全组、中度粮食不安全组和重度粮食不安全组）。用问卷评估食物消费频率。根据美国疾病控制与预防中心（CDC）的参考标准，当学生体重指数（BMI）与年龄的Z评分值大于 +2个标准差时，即认为该学生超重。
重度粮食不安全儿童中超重率最高（15.8%），其次是中度粮食不安全儿童（10.4%），粮食安全儿童为（6.9%）。在按年龄、性别和社会经济状况进行调整后，观察到相同的模式。粮食不安全的学生对高脂肪谷物、咸味食品和高能量密度甜食的消费量更大。
在学童中，粮食不安全与超重风险增加有关，这可能是因为粮食不安全程度越高的家庭购买更多低成本和高能量密度的食物。
