Objective: To describe the current status and trend of food consumption among Chinese residents., Methods: 23,470 households including 68,962 subjects were randomly sampled from 132 counties in 31 provinces, autonomous regions and municipalities. A 24-hour dietary recall method for 3 consecutive days was used to collect information on food intake, but the condiment intake was collected by weighting method., Results: The average food consumption per reference man per day of Chinese people included 402 g (urban/rural: 366 g/ 416 g) cereals; 276 g (urban/rural: 252 g/ 286 g) vegetables; 45 g (urban/rural:69 g/36 g) fruits; 79 g (urban/rural: 105 g/69 g) meats; 30 g (urban/rural:45 g/24 g) fishery products; 24 g (urban/rural: 33 g/20 g) eggs; 27 g(urban/rural: 66 g/ 11 g) dairy; 16 g legume; 42 g (urban/rural:44 g/41 g) edible oil; 12 g (urban/rural: 11 g/12 g) salt; 9 g (urban/rural: 11 g/8 g) soy sauce., Conclusions: For Chinese residents, the quality of diet had been improved and consumptions of animal products, milk, and edible oil had been increased, but the consumptions of dairy and legume products intake was still low which called for improvement. The unbalance was characterized as the downward trend in cereal, vegetable and fruit consumption but significant increased in animal products and oil intake among urban people. Dietary pattern of some subjects adopted a "high energy density" diet. Double burdens from under-nutrition and over-nutrition should both be considered as problems which asked for attention by the government and researchers.

Objective: To describe the current situation and trends of mean weight and height of the Chinese people., Methods: Subjects of 71,971 households from 31 provinces were selected by stratified multi-stage cluster random sampling method. Height from 210 136 and weight from 202 749 subjects aged 2-79 years were used to describe their trends of development during 1992-2002. The height of children younger than 3 years of age was measured by infant height bed while the others were measured by metal height pole within 0.1 cm accuracy. Fasting body weight was measured to the nearest 0.1 kg., Results: Data on the mean height (cm) of Chinese children aged 2, 6, 11, 17 years were gathered which include: 1) in urban area: boys as 90.1 (2y), 118.4 (6y), 144.9 (11y), 170.2 (17y); girls as: 89.0 (2y), 117.0 (6y), 145.8 (11y), 158.6 (17y); 2) in rural area:boys as 87.6 (2y), 113.1 (6y), 139.2 (11y), 166.3 (17y) while girls as 86.2 (2y), 112.9 (6y), 140.0 (11y), 157.0 (17y). When compared to the results from 1992, the average height increased among all age groups. The values of increase among different groups aged 2-5 years were seen as: 3.6 cm of boys in urban and 3.0 cm of boys in rural areas while 3.8 cm of girls in urban and 3.0 cm of girls in rural areas. Among the aged 6-19 year groups, the average increasing values of height were 3.1 cm, 3.4 cm, 2.8 cm and 3.1 cm of city boys, rural boys, city girls and rural girls, respectively versus adults as 0.7 cm, 0.9 cm, 0.6 cm and 1.0 cm, respectively. The mean weight (kg) of Chinese children aged 2, 6, 11, 17 years were listed as below: boys in urban area: 13.5 (2y), 22.2 (6y), 37.4 (11y), 58.7 (17y); girls in urban area: 12.7 (2y), 21.2 (6y), 36.7 (11y), 51.9 (17y); boys in rural area: 12.8 (2y), 19.4 (6y), 31.9 (11y), 54.9 (17y); girls in rural area: 11.9 (2y), 18.7 (6y), 31.8 (11y), 51.2 (17y). The average weights of all age groups on 2002 were all higher than their same age counterparts in 1992. The average increasing values of weight among children aged 2-5 years were 1.0 kg, 0.6 kg, 0.8 kg and 0.5 kg for city boys, rural boys, city girls and rural girls, respectively. Among the aged 6-19 year groups, they were 2.0 kg, 1.5 kg, 1.4 kg and 1.1 kg, while among the adults aged 20-70 years, they were 3.2 kg, 3.0 kg, 1.6 kg and 2.9 kg, respectively., Conclusion: Both mean weight and height had a remarkable increase and the physical status improved among all age groups for the last ten years.
