目的 确定每周口服维生素 D 补充剂是否会影响南非学童的生长、身体成分、青春期发育或肺量测定结果。设计 3 期双盲随机安慰剂对照试验。背景 南非开普敦社会经济处于弱势的城郊地区。参与者包括 1682 名就读公立小学的非洲黑人后裔儿童,基线年龄为 6-11 岁。干预措施 口服维生素 D3(10 000 IU/周)与安慰剂相比,为期 3 年。主要结果测量所有参与者的年龄别身高和年龄体重指数;针对青春期发育、肺活量和身体成分的 Tanner 评分,对 450 名另外参加嵌套子研究的儿童进行了测量。结果 随机接受维生素 D 治疗的儿童与安慰剂组相比,3 年随访时的平均血清 25-羟基维生素 D3 浓度较高(分别为 104.3 vs 64.7nmol/L;平均差 (MD) 39.7nmol/L,95%CI 37.6 至 41.9nmol/L)。随访时,维生素 D 组与安慰剂组相比,年龄别身高 z 评分(调整后 MD (aMD) -0.08,95%CI -0.19 至 0.03)或年龄体重指数 z 评分(aMD -0.04,95%CI -0.16 至 0.07)没有显着统计学差异。在子研究参与者中,与安慰剂相比,分配维生素 D 不会影响青春期发育评分、1 秒用力呼气量 (FEV1) 预测百分比、用力肺活量 (FVC) 预测百分比、FEV1/FVC 预​​测百分比、脂肪量或无脂肪量。结论 每周口服 10 000 IU 维生素 D3 可以提高南非学童的维生素 D 状态,但不会影响生长、身体成分、青春期发育或肺量测定结果。试验注册号 ClinicalTrials.gov NCT02880982,南非国家临床试验注册号 DOH-27-0916-5527。
Objective To determine whether weekly oral vitamin D supplementation influences growth, body composition, pubertal development or spirometric outcomes in South African schoolchildren. Design Phase 3 double-blind randomised placebo-controlled trial. Setting Socioeconomically disadvantaged peri-urban district of Cape Town, South Africa. Participants 1682 children of black African ancestry attending government primary schools and aged 6–11 years at baseline. Interventions Oral vitamin D3 (10 000 IU/week) versus placebo for 3 years. Main outcome measures Height-for-age and body mass index-for-age, measured in all participants; Tanner scores for pubertal development, spirometric lung volumes and body composition, measured in a subset of 450 children who additionally took part in a nested substudy. Results Mean serum 25-hydroxyvitamin D3 concentration at 3-year follow-up was higher among children randomised to receive vitamin D versus placebo (104.3 vs 64.7 nmol/L, respectively; mean difference (MD) 39.7 nmol/L, 95% CI 37.6 to 41.9 nmol/L). No statistically significant differences in height-for-age z-score (adjusted MD (aMD) −0.08, 95% CI −0.19 to 0.03) or body mass index-for-age z-score (aMD −0.04, 95% CI −0.16 to 0.07) were seen between vitamin D versus placebo groups at follow-up. Among substudy participants, allocation to vitamin D versus placebo did not influence pubertal development scores, % predicted forced expiratory volume in 1 s (FEV1), % predicted forced vital capacity (FVC), % predicted FEV1/FVC, fat mass or fat-free mass. Conclusions Weekly oral administration of 10 000 IU vitamin D3 boosted vitamin D status but did not influence growth, body composition, pubertal development or spirometric outcomes in South African schoolchildren.
