目的 探讨中老年人营养素摄入量与骨密度的关系.方法 对200名在北京协和医院健康体检者进行膳食调查及测量腰椎(L)2~4、股骨大粗隆及股骨颈的骨密度,并分为中青年男女组、老年前期男女组和老年男女组,各组及性别间进行比较.结果 男性老年组平均每日蛋白质、碳水化合物、热量的摄入量分别为(71.4±11.7)g、(294.2±54.7)g和(2196.9±311.3)kcal,显著低于男性中青年组;男性中青年组平均每日蛋白质、碳水化合物、热量的摄入量分别为(91.7±19.5)g、(81.8±85.2)g和(2716.0±451.7)kcal.钙摄入量以女性老年组为最低,平均每日摄入量为(362.0±167.1)mg;男性老年组L2~4、股骨大粗隆及股骨颈的骨密度异常发生率显著高于男性中青年组(P<0.05)及男性老年前期组(P<0.05);女性各组L2~4、股骨大粗隆及股骨颈的骨密度异常发生率的差异均有统计学意义(P<0.05),尤以老年组和中青年组显著(P<0.0001);男性老年前期组和老年组骨密度异常发生率显著低于女性老年前期组(P<0.05)和女性老年组(P<0.05).结论 影响老年女性骨密度异常的因素之一可能为钙摄入的减少,脂肪摄入量的增加可能是影响骨健康的因素之一. |

Objective To study the relationship between intake of nutrients and bone density in the middle-aged and the old people. Methods Dietary investigation was conducted and bone densities of lumbar 2-4, tuberositas of femur and the neck of femur were measured in 200 healthy subjects who received physical check-up in our hospital. Subjects were distributed into 6 groups including young or middle-aged,pre-old and old groups of men and women.Comparison was conducted within those groups.Results The average intake of protein, carbohydrate and energy per day in old men-group were (71.4±11.7)g,(294.2±54.7)g and (2196.9±311.3) kcal, respectively, which were significantly lower than those in young or middle-aged groups,and the average amounts of protein, carbohydrate and energy intake per day in old men-group were (91.7±19.5)g, (81.8±85.2)g and (2716.0±451.7)kcal, respectively. The average intake of calcium in women-old group was (362.0±167.1)mg, the lowest in the groups. The incidence of abnormal bone densities of lumbar 2-4, the tuberositas of femur and the neck of femur in old men group was significantly higher than those in young or middle-aged men groups (P<0.05 ) and the preold men group. There were significantly different incidence rates of abnormal bone densities between the 3 women groups (P<0.05), especially between young or middle-aged groups and in the old women-group(P<0.0001 ). The incidences of abnormal bone density in pre-old men group and old men group were significantly lower than those in-pre-old and old women groups. Conclusion The decrease of calcium intake seemed to be one of the factors leading to abnormity of bone density in old women. While the increase of calcium intake served as one of the nutritional factors affecting the bones. |
