To evaluate Ca intake and its association with cardiometabolic risk factors during childhood.
A cross-sectional study with a representative sample. Food consumption was assessed through three 24 h dietary recalls. Anthropometry, body composition and biochemical measurements were also conducted.
Viçosa, Minas Gerais, Brazil.
Children between 8 and 9 years old (n 350) enrolled in public and private schools in the urban area of the municipality of Viçosa.
Almost all children had inadequate intake of Ca (97·4 %), especially those with low income, non-white and who studied in public schools. Foods that contributed most to Ca intake were 'milk' and 'cheeses and yoghurts' (R 2=0·66 and 0·13, respectively), and intake of 'milk' was correlated with 'chocolate milk powder' intake (r=0·538, P<0·01). Children with lower Ca intake had a higher prevalence of increased C-reactive protein (prevalence ratio=2·93; 95 % CI 1·21, 7·07), increased waist circumference (prevalence ratio=2·86; 95 % CI 1·01, 8·13) and a lower prevalence of high LDL cholesterol (prevalence ratio=0·64; 95 % CI 0·41, 0·99).
Lower Ca intake was associated with excess abdominal adiposity and subclinical inflammation in Brazilian children. Monitoring of adequate Ca intake is important, especially in poorer communities.
评估儿童时期钙摄入量及其与心血管代谢危险因素的关系。
具有代表性样本的横断面研究。通过三次 24 小时膳食回忆评估食物消耗。还进行了人体测量、身体成分和生化测量。
巴西米纳斯吉拉斯州维索萨市。
参加维索萨市市区公立和私立学校的 8 至 9 岁儿童（n 350）。
几乎所有儿童的钙摄入量都不足（97.4%），尤其是收入较低、非白人和在公立学校上学的儿童。对钙摄入量贡献最大的食物是“牛奶”和“奶酪和酸奶”（R 2分别为 0.66 和 0.13），而“牛奶”的摄入量与“巧克力奶粉”的摄入量呈正相关（r=0.538，P<0.01）。钙摄入量较低的儿童，C 反应蛋白升高的患病率更高（患病率比=2.93；95%CI 1.21,7.07），腰围增加的患病率更高（患病率比=2.86；95%CI 1.01,8.13），而高密度脂蛋白胆固醇升高的患病率较低（患病率比=0.64；95%CI 0.41,0.99）。
巴西儿童钙摄入量较低与腹部肥胖和亚临床炎症增加有关。监测充足的钙摄入量很重要，特别是在较贫困的社区。
