title: Effects of Socioeconomic Status on Nutrition in Asia and Future Nutrition Policy Studies.
abstract: Evidence of health disparities has been reported around the world. One of the intermediate factors between socioeconomic status (SES) and health is nutrition. Many studies reported socioeconomically disadvantaged people had more risk of obesity and lifestyle-related diseases than others in western society. Micronutrient intake affected by SES, but little evidence indicates that SES affects either energy intake or the macronutrient composition of the diet in western countries. In contrast, there is not enough evidence of a consistent relationship between SES and nutrition in Asian countries at present. The present status of nutrition disparities in Asia is considered to vary by economic level of the country. For developing countries in Asia, India and Vietnam, SES associates with BMI positively in women. For relatively developed countries in Asia, Korea and Japan, SES associates with BMI negatively in women. Low SES groups consume more carbohydrate, and less protein and fat, so not only micronutrient but also macronutrient intake is affected by SES both in developing and in developed Asian countries. There are some studies on the pathway from SES to diet/nutrition. The association between low SES and obesity may be mediated, in part, by the low cost of energy-dense foods, concern about food price and dietary knowledge. Nutrition policy research is required to reduce nutrition disparities in Asia. We need a collaborative study of the impact of potential political options on diet and on health with other academic fields.
