A major concern is the ubiquitous presence of fast food and takeaway outlets within easy walking distance of schools, particularly in the light of the increasing burden of childhood obesity. Here, the associations between the schoolchildren's weights, their consumption of fast food and takeaway outlets were examined in a deprived inner London Borough.
This is a cross-sectional study.
193 schoolchildren (aged between 11 and 14 years old) participated in this study.
Body mass index (BMI) percentiles specific for age and gender were obtained. Frequency of food and drinks purchased from fast food outlets and takeaway outlets over a weekly period and preferred types of drinks and food products usually consumed were measured.
More than 50% of the children in our survey purchased food or drinks from fast food or takeaway outlets twice or more a week, with about 10% consuming fast food or drinks from these outlets daily. About 70% of these children from Black ethnic groups and 54% of Asians purchased fast food more than twice a week. BMI has a significantly inverse relationship to fast food consumption. However, when age and gender are accounted, the BMI age-gender percentile is no longer significantly related to fast food consumption.
This study revealed a very high frequency of fast food consumption among the schoolchildren. Taste, quick access and peer influence were major contributing factors. These schoolchildren are exposed to an obesogenic environment, and it is not surprising that in this situation, many of these children are already overweight and will likely become obese as adults.
一个主要问题是学校附近很容易步行到达的地方普遍存在快餐店和外卖店,尤其是考虑到儿童肥胖负担日益加重的情况。在此,我们在伦敦市中心一个贫困区研究了学童体重、他们对快餐的消费以及外卖店之间的关联。
这是一项横断面研究。
193名学童(年龄在11至14岁之间)参与了本研究。
获取了按年龄和性别划分的特定身体质量指数(BMI)百分位数。测量了一周内从快餐店和外卖店购买食品和饮料的频率,以及通常消费的首选饮料和食品类型。
在我们的调查中,超过50%的儿童每周从快餐店或外卖店购买食品或饮料两次或更多次,约10%的儿童每天从这些店消费快餐或饮料。这些儿童中,约70%的黑人族裔和54%的亚裔每周购买快餐超过两次。BMI与快餐消费呈显著负相关。然而,在考虑年龄和性别因素后,BMI年龄 - 性别百分位数与快餐消费不再显著相关。
本研究揭示了学童中快餐消费频率非常高。口味、便捷获取和同伴影响是主要促成因素。这些学童暴露在致胖环境中,在这种情况下,许多儿童已经超重且成年后很可能会肥胖,这并不奇怪。
