宝宝缺钙 问题多数在吸收

●足月宝宝喝奶量够且母亲营养均衡,钙摄入量一般都能保证

●科学研究表明,补钙无助于促进宝宝体格发育

在铺天盖地的各种钙产品广告攻势下,很多新手爸妈都会纠结于要不要给宝宝补钙。广州市妇女儿童医疗中心专家介绍,儿童要不要补钙,要视儿童生长发育、饮 食、疾病等情况而定,不能一概而论。但一般来说足月的孩子只要喝奶量够、母亲营养均衡,一般不会缺钙。出现缺钙,问题多在吸收上,比如冬天户外活动晒太阳 时间少,促进钙吸收的维生素D合成得就少。只有当宝宝无法从食物中摄入足量钙时,才需要另外补钙。科学研究表明,补钙无助于促进宝宝的体格发育。

食物无法保证足量钙 才要另外补

林穗方介绍,母乳中的钙比较容易吸收,配方奶粉中也会强化钙成分,因此,只要孩子喝奶量够、乳母本身饮食均衡,一般都不需要补钙。但是早产、低出生体 重、双胞或多胞胎婴儿需要额外补充钙,可以用母乳强化剂、特殊早产儿配方奶,或额外增加维生素D和钙补充剂。只有在无法从食物中摄入足量钙时,才需要在医 生的指导下适量使用钙补充剂。

林穗方表示,是否缺钙要看具体情况,不是每个孩子都要补,过量的钙摄入反而干扰锌、铁吸收,造成锌和铁的 缺乏,还可能导致便秘、浮肿、多汗、厌食、恶心等症状,严重者甚至出现肾结石、血管钙化等。市妇女儿童医疗中心保健部儿童保健科医师刘贤指出,以下几种情 况要特别注意:

1.出现枕突别盲目补钙

4月龄宝宝畅畅(足月儿),纯母乳喂养,每天摄入奶量1000~1200毫升。近日畅畅出现枕秃,同时偶伴睡眠不好、出汗症状。畅畅妈妈听邻居说这是缺钙导致的,就忙着给畅畅补钙。

专家解答:

奶量足、妈妈不缺钙,不需盲目补钙

刘贤介绍,根据中国营养学会推荐的膳食钙供给量,0~6月龄宝宝每日应摄入300毫克钙。而在妈妈没有严重缺钙的情况下,每100毫升母乳中含钙30毫 克。以此计算,目前畅畅每日摄入奶量1000~1200毫升,通过母乳就已经可以得到比较充足的钙源,此时不需要再盲目地补钙。

刘贤表示,冬天家长要做的是多带畅畅去户外晒太阳,尽量暴露皮肤,使阳光与皮肤直接接触,当然注意不要冻着宝宝;同时给畅畅口服预防量的维生素D(鱼肝油)。因为畅畅是纯母乳喂养,建议畅畅妈妈保证优质蛋白饮食,并可以适量补充钙剂。

2.骨碱性磷酸酶检测处于

预防水平可补预防量维生素D

8月龄跃跃,目前人工喂养每天摄入奶量750~800毫升,已经添加果泥、蛋黄、菜泥、肉泥等辅食。骨碱性磷酸酶检测210U/L。

专家解答:

每天进行户外活动,定期监测发育状况

刘贤介绍,骨碱性磷酸酶(NBAP)近年来主要用于小儿佝偻病早期诊断和亚临床鉴别的特异性参考指标。正常水平的参考值是200u/L以下, 预防水平 是200u/L~250u/L,医疗水平是250~300u/L。跃跃的骨碱性磷酸酶检测值210U/L,处于预防水平。

她提醒,我国 每日推荐的膳食钙供给量6月龄到1岁为400毫克。对于人工喂养的孩子,配方奶粉中含有的钙是母乳中的2~4倍,但其钙的吸收率相对于母乳较低,但是如果 没有其他消化道的问题,跃跃从每天750~800毫升配方奶获得的钙源是充足的。加上跃跃添加的辅食中也可以补充一部分钙源,所以跃跃也不用额外补充钙 剂。但是,此时需要给跃跃补充预防量的维生素D,每天带跃跃户外活动2小时以上,并且要定期去医院监测体格发育状况,接受医生专业指导。

3.补钙不能强壮体格

1岁的阳阳(男孩)身长71.5厘米、体重8.2千克,与同年龄段的宝宝比,阳阳长得略显瘦小。阳阳妈妈开始给阳阳补充钙剂,认为补充钙剂可以增强阳阳骨骼和身体发育,让他变得健壮起来。

专家解答:

研究表明补钙不能促进体格发育

根据中国7岁以下儿童生长发育参考标准,12月龄男童身长的中等范围为71.2~82.1厘米,体重中等范围是8.06~12.54千克。参考此标准, 阳阳体格发育处于中等范围的中下水平,但还不属于生长迟缓及低体重。喂养水平、疾病状态、遗传因素、睡眠、运动情况等都会影响到宝宝的体重、身长发育状 态。加强营养、保证充足睡眠、适量的户外活动及提高免疫力做到常见疾病预防都会促进宝宝体格的健康发育。即使宝宝体格发育处于生长迟缓或低体重状态,也应 该去医院接受相应检查,结合医生临床专业指导进行相应身高、体重促进治疗。

刘贤表示,目前科学研究表明,补钙并不能促进宝宝的体格发育水平,因此阳阳妈妈盲目给阳阳补钙的做法是不科学的。

宝宝晒太阳少 容易影响钙吸收

专家介绍,2岁以下的婴幼儿生长迅速,对钙的需要量相对较高,是钙缺乏的高危人群,尤其是母亲妊娠期钙、维生素D摄入不足,早产或低体重儿、双胞胎或多 胞胎等情况,会使胎儿在妈妈体内时储存的钙不足,造成婴儿出生早期缺乏钙。母乳不足及断母乳后没用配方奶或其他奶制品替代,也是缺钙的重要因素。腹泻、胃 肠道疾病使肠道钙吸收利用不良,维生素D不足,也容易引起钙的缺乏。

广州市妇女儿童医疗中心保健部儿童保健科科长林穗方表示,多数儿童 的缺钙问题不是出在摄入量不足,而是在于吸收。钙的吸收和维生素D有很大关系,维生素D除了胎儿期从母体获得的储存以外,还可通过食物摄入以及阳光照射在 皮肤上后体内合成。冬天阳光不足,婴儿户外活动时间少、裸露在外的皮肤也少,就会影响皮肤合成维生素D。

Low full-term babies drink enough milk, and mother a balanced, calcium intake is generally guaranteed

Low scientific studies have shown that calcium supplements to promote baby's physical development

In a frenzy of various calcium products advertising campaigns, many new parents will

struggle with baby do you want to calcium supplements.

City women and children medical center, health ministry child care practitioner fund pointed out that the following situation should pay special attention:

1. A pillow tu don't blindly calcium supplements

4 4 months baby chang chang (full moon), exclusive breastfeeding, 1000 ~ 1200 ml of milk every day. Chang chang appeared recently pillow bald, even with poor sleep, sweating symptoms at the same time. Chang chang mother to listen to the neighbors said that it is caused by calcium deficiency, was busy to chang chang calcium supplements.

The expert answers:

Milk, mother not lack calcium, do not need to blindly calcium supplements

Fund, according to the Chinese nutrition society recommended dietary calcium supply, 0 ~ 6 months baby daily intake of 300 micrograms of calcium. In mother under the condition of no serious lack calcium, 30 per 100 ml of milk contains calcium milli grams. This

calculation, the chang chang 1000 ~ 1200 ml of milk a day, through breast milk can get more sufficient calcium source, at this time no longer blindly calcium supplements.

Fund, says parents need to do is take chang chang in winter to go outside in the sunshine, try to exposed skin, sunlight, direct contact with the skin, of course, be careful not to frozen baby; At the same time to chang chang oral prevention amount of vitamin D (cod liver oil). Because chang chang is exclusive breastfeeding, it is suggested that chang chang mother guarantee the high quality protein diet, and can supplement calcium.

2. Detection of bone alkaline phosphatase in

Prevention level complemented to prevent vitamin D

8 months ahead, artificial feeding of milk per day at present is 750 ~ 800 ml, have added puree, egg yolk, puree, glue and other side dish. 210 u/L of bone alkaline phosphatase. The expert answers:

The growth of outdoor activities on a daily basis, regular monitoring

Fund, bone alkaline phosphatase (NBAP) in recent years is mainly used for infantile

rickets in early diagnosis and the clinical identification of specific reference index. Under the normal reference value is 200 u/L and prevention level is 200 u/L ~ 250 u/L, medical level is 250 ~ 300 u/L. Ahead of bone alkaline phosphatase values 210 u/L, at the level of prevention.

She reminded, our country the recommended daily dietary calcium supply 6 months to 1 year old is 400 mg. For children, artificial feeding formula contains calcium in breastmilk is 2 ~ 4 times, but its relative to the mother's milk is low in calcium absorption, but if there are no other gastrointestinal problems, yueyue from 750 ~ 800 ml every day formula for calcium source is sufficient. With yueyue part added side dish can also supplement calcium source, yueyue so no extra calcium agent also. But, this time the need to give prevention amount of vitamin D, yueyue with yueyue outdoor activities for more than 2 hours a day, and go to a hospital regularly monitor physical development status, accept the doctor professional guidance.

3. Calcium can not be strong physique

1, Yang Yang (boy) 71.5 cm in length, weight 8.2 kg, and the baby than with age, Yang Yang grow slightly smaller. Yang Yang mother began to Yang Yang added calcium 4

5 supplements that supplement calcium supplements can enhance Yang Yang bones and body development, let him become strong.

The expert answers:

Research shows that calcium supplements can't promote physical development

According to the growth and development of Chinese children under the age of 7

reference standard, 12 months boy medium range of 71.2 ~ 71.2 cm in length and weight of medium range from 8.06 to 12.54 kg. Refer to this standard, Yang Yang physique growth in the middle range of the middle and lower levels, but also do not belong to the slow growth and low weight. Feeding level, disease status, genetic factors, sleep,

movement and so on will affect the baby's body weight, body length and development of the state. Strengthen nutrition, assure enough sleep, just the right amount of outdoor

activities, and enhance immunity to common diseases prevention will promote the health of the baby's physical development. Even if the baby's physical development is in a state of growth retardation or low weight, should also should go to hospital for check

Fund, said the current scientific studies have shown that calcium supplements does not promote the level of baby's physical development, therefore, Yang Yang's mother blind to Yang Yang filling calcium is not scientific.

Baby sunbathe less easy to affect calcium absorption

Expert introduction, infants and young children under the age of 2, rapid growth of calcium requirements are relatively high, calcium is the lack of high-risk groups, especially the mother insufficient calcium and vitamin D intake during pregnancy, preterm birth and low birth weight, twins or multiple births, etc., can make the baby in her mother when stored in the body of calcium deficiency, cause baby born early lack of calcium. After enough milk and milk broken useless formula or other dairy products replace, is also an important factor of calcium deficiency. Diarrhea, gastric bowel disease make use bad intestinal calcium absorption, vitamin D deficiency, also easy to cause the lack of calcium.

Guangzhou women and children health care center for child health care department chief Lin Suifang said that most children calcium deficiency problems not intake is insufficient, it is absorbed. Has a lot to do with the absorption of calcium and vitamin D, vitamin D

besides prenatal obtained from mother storage, but also through food intake, and sunlight on the skin after synthesis in the body. Lack of sunshine in the winter, the baby outdoor activities less time and less exposed skin, can affect skin synthesis of vitamin D.
