There is increasing evidence that the school food environment contributes to childhood obesity and health in various locations. We investigated the influence of fast-food stores and convenience food stores (FS and CS, respectively) on growth and body composition in a range of residential densities for North-east Asian food culture.
Anthropometrics and birth weight of schoolchildren were obtained. Geocoded mapping of schools and food outlets was conducted. Multivariable linear regression models, adjusted for father's ethnicity and education, as well as for household income, pocket money, birth weight, physical activity, television watching, food quality and region, were used to predict body composition from school food environments.
Elementary schools and school neighbourhoods in 359 townships/districts of Taiwan.
A total of 2283 schoolchildren aged 6-13 years from the Elementary School Children's Nutrition and Health Survey in Taiwan conducted in 2001-2002.
Remote and socially disadvantaged locations had the highest prevalence of lower weight, BMI, waist circumference and triceps skinfold thickness. Food store densities, FS and CS, were highest in urban Taiwan and lowest in remote Taiwan. In the fully adjusted models, FS densities predicted weight and BMI in boys; there was a similar association for waist circumference, except when adjusted for region. FS densities also predicted height for girls. Except for weight and BMI in boys, CS did not have effects evident with FS for either boys or girls.
A high FS density, more than CS density, in Taiwan increased the risk of general (BMI) and abdominal (waist circumference) obesity in boys and stature in girls. These findings have long-term implications for chronic disease in adulthood.
越来越多的证据表明，学校食品环境对各地儿童肥胖和健康有影响。我们调查了快餐店（FS）和便利店（CS）对东北亚饮食文化不同居住密度地区儿童生长和身体成分的影响。
获取了学童的人体测量数据和出生体重。对学校和食品店进行地理编码映射。采用多元线性回归模型，根据父亲的种族和教育程度，以及家庭收入、零花钱、出生体重、体力活动、看电视、食物质量和地区进行调整，从学校食品环境预测身体成分。
台湾 359 个乡镇/区的小学和学校社区。
2001-2002 年台湾进行的《小学生营养与健康调查》中 2283 名 6-13 岁的学童。
偏远和社会劣势地区体重、BMI、腰围和三头肌皮褶厚度较低的比例最高。台湾城市的食品店密度最高，而偏远地区的 FS 和 CS 密度最低。在完全调整的模型中，FS 密度预测了男孩的体重和 BMI；与区域调整相比，腰围也存在类似的关联。FS 密度也预测了女孩的身高。除了男孩的体重和 BMI 外，CS 对男孩或女孩的 FS 没有明显影响。
台湾 FS 密度高（高于 CS 密度），增加了男孩普遍肥胖（BMI）和腹部肥胖（腰围）以及女孩身高的风险。这些发现对成年后慢性病有长期影响。
