application/pdf, 学術雑誌論文, Objective: To investigate dietary quality among Japanese adults with a high vegetable diet, to consider dietary recommendation for vegetable intake. Design and setting: In the cross-sectional study of the National Health and Nutrition Survey 2003, we conducted the secondary analyses. The food-weighing method in one-day assessed the dietary intake. From 11,630 subjects, 2,305 men and 2,312 non-pregnant/lactating women, aged 20-69 y, and with an energy intake between 1,500 and 3,712 kcal were selected. Associations between vegetable, nutrient-density, and food intake were analyzed according to tertile cutoff: low vegetable diet (LVD), medium vegetable diet (MVD), or high vegetable diet (HVD). Differences across subgroups were tested after age adjustment. Results: Mean vegetable intakes were 309g for men and 318g for women. Only 35% of Japanese met the vegetable intake (VI) recommendation of≧350g/d. VI had a positive association with age. Men 20-29 y-old and women 30-39 y-old were the subjects with the lowest VI. HVD subjects had higher intake for most food groups, whereas wheat in men; and wheat, sweets, and alcoho\l in women were negatively associated with VI. Main sources of energy for men and women with HVD were rice, wheat, and meat. HVD also had higher micronutrient-density. Conclusion: These analyses demonstrated the beneficial effects of HVD on dietary quality in the population studied. We concluded recommendations for adequate vegetable intake are expected to improve diet quality among Japanese adults, especially for the group aged 20-39.

To analyze demographic, health-related behaviors, eating habit and knowledge associated with vegetable intake.Secondary analyses using the dataset from the National Health and Nutrition Survey 2003. Food intake data measured by the food-weighing method in one-day and a questionnaire assessed the dietary intake and health-related behaviors, eating habit and knowledge. This study was made in Japan. The data of 1742 men and 2519 nonpregnant/nonlactating women, aged 20-69 years, energy intake between percentiles 1 and 99 were included. Vegetable intake was analyzed according to the Japanese vegetable recommendation (or=350 g/day) after age adjustment.Average of VI was 307 g/day in men and 297 g/day in women. Only 35% of men and 31% of women met the recommended amount of vegetable intake. Japanese from city areas, aged 60-69 years, had the highest vegetable intake and subjects from metropolitan areas had the lowest vegetable intake. Depending on the age groups, risks for low vegetable intake in Japanese were found in subjects with skipping meals, alcohol intake and history of smoking.To increase vegetable intake, it is necessary to provide more nutritional education and lifestyle-related diseases education.
