The purpose of this study was to investigate the dietary calcium intake and associated other dietary factors among representative sample of Japanese general men and women.
Data was obtained by linking NIPPON DATA80 and 90 with the corresponding National Nutrition Surveys held in 1980 and 1990. We analyzed data for 10,422 subjects (4585 men and 5837 women) in NIPPON DATA80 and 8342 subjects (3488 men and 4854 women) in NIPPON DATA90. Calcium intake was calculated by age groups. Dietary calcium intake was classified into quintiles and physical, life-style, and dietary parameters were examined across the quintiles.
For both men and women, calcium intake tended to be positively associated with age in NIPPON DATA80 and 90, and there were significant differences in estimated calcium intake between age groups. Calcium intake tended to be positively associated with age, protein, fat, saturated fat, vitamins A and C, sodium, potassium, and iron for men and women. Calcium intake also tended to be positively associated with intake of nuts, potatoes, sugar and sweeteners, soybeans and legumes, fruits, green and yellow vegetables, other vegetables, mushrooms, sea algae, fish and shellfish, eggs, and milk and dairy products for men and women.
The characteristics of calcium intake in Japanese people were able to be clarified by using the baseline data of NIPPON DATA and the National Nutrition Survey.
本研究旨在调查日本代表性男女群体的膳食钙摄入量及相关其他膳食因素。
通过将 NIPPON DATA80 和 NIPPON DATA90 与 1980 年和 1990 年相应的全国营养调查相联系,获取数据。我们分析了 NIPPON DATA80 中的 10422 名受试者(4585 名男性和 5837 名女性)和 NIPPON DATA90 中的 8342 名受试者(3488 名男性和 4854 名女性)的数据。按年龄组计算钙摄入量。将膳食钙摄入量分为五分位数,并在五分位数中检查身体、生活方式和膳食参数。
在 NIPPON DATA80 和 NIPPON DATA90 中,男性和女性的钙摄入量均随年龄增长而呈正相关,且各年龄组间的估计钙摄入量存在显著差异。钙摄入量与男性和女性的年龄、蛋白质、脂肪、饱和脂肪、维生素 A 和 C、钠、钾和铁呈正相关。钙摄入量也与男性和女性坚果、土豆、糖和甜味剂、大豆和豆类、水果、绿色和黄色蔬菜、其他蔬菜、蘑菇、海藻、鱼和贝类、鸡蛋以及牛奶和奶制品的摄入量呈正相关。
通过使用 NIPPON DATA 的基线数据和全国营养调查,能够阐明日本人钙摄入量的特点。
