Hara said another factor in Japan is regularly mandated childcare health checks. Parents of infants receive reminders from the local government, and children are given health checks at school, including measuring height and weight.

原光彦说，另一个因素是日本强制儿童定期体检。婴儿的父母会收到当地政府的提醒，孩子们会在学校接受健康检查，包括测量身高和体重。

Still, even Japan has not escaped entirely the growing trend toward overweight children and childhood obesity, which in Japan, like elsewhere, tends to affect those from less wealthy families.

然而，即使是日本也未能完全摆脱超重和肥胖儿童日益增多的趋势，这在日本和其他地方一样，往往会影响那些来自不太富裕家庭的儿童。

"Children in poverty are more likely to be overweight because families try to cut costs," Hara said. "As a result, they eat less protein but consume more carbs and sugar, which leads to obesity."

原光彦说，“贫困儿童更有可能超重，因为家庭在努力缩减开支。因此他们吃的蛋白质更少，但却吃了更多的碳水化合物和糖，这会导致肥胖。”

School lunches are all the more important to children in such situations, he said.

他说，在这种情况下，学校午餐对孩子们来说更加重要。
