To describe the differences in diet intake frequency of adults in 10 areas surveyed by China Kadoorie Biobank (CKB) project.
CKB project recruited voluntary residents aged 30-79 years from 5 urban areas and 5 rural areas in China. The baseline survey was conducted among 512 891 eligible subjects during 2004-2008. The intake frequencies of 12 food groups were assessed through in-person interviews and analyzed. The results were adjusted for age and sex structure of the study population.
Rice was the main cereal consumed every day in urban areas (99.0%) and rural areas (99.9%) in southern China, while wheat was the main cereal consumed every day in rural areas (99.0%) and Qingdao (88.4%) in northern China. Most subjects in Henan (98.8%) consumed other staple food every day. The lowest proportion of daily intake of fresh vegetables was observed in Gansu (74.0%) . In both southern and northern areas, urban subjects had higher proportions of daily intakes of fresh fruits, preserved vegetables, and meat than rural subjects. Similar results were found when comparing the proportions of intakes of poultry and fish/seafood at least 1 day every week. Contrast to southern China (urban: 6.5%, rural: 6.9%) , the proportions of daily intake of fresh eggs were higher in both urban areas (37.1%) and rural areas (14.6%) in northern China. The highest proportions of daily intake of soybean products and dairy products were observed in Harbin (10.0%) and Qingdao (34.3%).
The intake of cereal, fresh eggs and soybean products differed between the south and the north of China. The intake of meat, poultry, fish/seafood, fresh fruits, preserved vegetables and dairy products varied considerably between urban areas and rural areas.
描述中国嘉道理生物样本库（CKB）项目所调查的10个地区成年人饮食摄入频率的差异。
CKB项目从中国5个城市地区和5个农村地区招募了30 - 79岁的自愿居民。在2004 - 2008年期间，对512891名符合条件的受试者进行了基线调查。通过面对面访谈评估了12个食物组的摄入频率并进行分析。结果针对研究人群的年龄和性别结构进行了调整。
在中国南方，大米是城市地区（99.0%）和农村地区（99.9%）每天食用的主要谷物，而在中国北方，小麦是农村地区（99.0%）和青岛（88.4%）每天食用的主要谷物。河南的大多数受试者（98.8%）每天食用其他主食。甘肃新鲜蔬菜的每日摄入量比例最低（74.0%）。在南方和北方地区，城市受试者新鲜水果、腌制蔬菜和肉类的每日摄入量比例均高于农村受试者。比较每周至少1天摄入家禽和鱼/海鲜的比例时也发现了类似结果。与中国南方（城市：6.5%，农村：6.9%）相比，中国北方城市地区（37.1%）和农村地区（14.6%）新鲜鸡蛋的每日摄入量比例更高。哈尔滨（10.0%）和青岛（34.3%）大豆制品和乳制品的每日摄入量比例最高。
中国南北地区谷物、新鲜鸡蛋和大豆制品的摄入量存在差异。城市地区和农村地区肉类、家禽、鱼/海鲜、新鲜水果、腌制蔬菜和乳制品的摄入量差异很大。
