摘      要：Objective To investigate the effect of yogurt supplementation on the growth of preschool children in Beijing suburbs. Methods Four hundred and two preschool children (217 males, 185 females), aged 3-5 years, whose height for age and/or weight for age were less than the reference level, were selected as subjects from 7 kindergartens in Beijing Fangshan District. The subjects were divided randomly into control group (CG, 201) and yogurt supplemented group (YG, 201). Each subject in YG was given one serving of yogurt (125 g) for 5 days a week from March to December in 2001, while nothing additional was provided to CG. All subjects kept their usual diet during the study. Anthropometry (body height and weight and upper-arm circumference) and the bone mineral density (BMD) of forearm were measured every 3 months. Disease status and dietary intake were also recorded and assessed. Results The intake of calcium, zinc, and vitamin B2 in YG was significantly higher than that in CG. The incidence and duration of upper-respiratory infection and diarrhea of children in YG were significantly less than those in CG. The height gain of children in YG was significantly higher than that in CG after yogurt was supplemented for 3, 6, and 9 months (P0.05) (1.90±0.49 cm vs 1.77±0.54 cm, 3.83±0.57cm vs 3.64±0.66 cm and 5.43±0.69 cm vs 5.24±0.76 cm, respectively). The weight gain of children in YG was significantly higher than that in CG after yogurt was supplemented for 3, 6, and 9 months (P0.05) (0.70±0.43 kg vs 0.49±0.35 kg, 0.98±0.62 kg vs 0.80±0.60 kg and 1.42±0.76 kg vs 1.20±0.67 kg, respectively). The BMD of children in YG was significantly higher than that in CG after yogurt was supplemented for 9 months (P0.05) (0.415±0.058 g/cm2 vs 0.400±0.065 g/cm2). Conclusion Yogurt is beneficial to the improvement of calcium, zinc, and vitamin B2 intake, the decreasing of the incidence and duration of upper-respiratory infection and diarrhea, and the promotion of the health and the growth an
