A longitudinal survey of health and nutrition in China was undertaken in eight provinces (Liaoning, Jiangsu, Shandong, Henan, Hubei, Hunan, Guangxi, Guizhou). Data were collected in 1989, 1991, 1993 and 1997. The 1991 and 1993 data were used to investigate factors affecting intrahousehold food distribution. The discrepancy score and the ratio of food share to energy share were used to describe food distribution within households. Findings indicated that, in most cases, males had a higher proportion of nutrient intake than females, particularly in the young adult group where men presented with a higher discrepancy score than women for energy and all nutrients observed. The food and nutrient distribution tends to be more favourable to the middle-aged group, although the youngest group, while accepting relatively smaller amounts of cereals, ate much bigger amounts of meat, dairy products and fruits. Household members with higher incomes are more favoured in terms of food consumption and nutrient intake. Household leaders accepted a higher share of energy and nutrients in comparison with other members of the household across all age and sex groups. Administrators and people working in service or trade industries in rural areas are favoured in terms of food distribution relative to farmers and manual workers. Well-educated people accepted a better food allocation than others and those in employment received more nutrients than the unemployed. The 'contribution rule' (individuals who make a greater contribution to the family receive a larger share of the family's food) is discussed and deemed to be applicable in explaining the discrepancy in food distribution and nutrient intake among household members.
