Development of a WHO growth reference for school-aged children and adolescents de Onis M, Onyango AW, Borghi E, Siyam A, Nishida C, Siekmann J. For BMI-for-age across all centiles the magnitude of the difference between the growth and development of preschool-age children two curves at age 5 years is mostly 0.
They fill the gap in growth curves and provide an appropriate reference for the 5 to 19 years age group. Recent global estimates indicate that over a quarter of children under 5 years of age are stunted, and consequently are at an increased risk of dying and other adverse consequences throughout life. 8,10 Analysis from one of the studies indicated that a dose of 10 mg zinc per day for 24 weeks led to a net a gain of 0. Although zinc supplementation is considered to be safe8,10 and has been recommended as an effective intervention to reduce morbidity associated with diarrhoea and lower respiratory infections in young children8,12, the likely need for daily administration of zinc supplements presents a number of programmatic challenges. In countries with known widespread zinc deficiencies and high levels of stunted children, preventive zinc supplementation has a small but significant positive effect on linear growth. The limited impact of zinc supplementation suggests that such an intervention should be part of more comprehensive efforts to improve the general nutritional status of children, particularly in the first two years of life. Levels and trends in child malnutrition.

Impact of maternal education about complementary feeding and provision of complementary foods on child growth in developing countries. Rates of malnutrition in Bangladesh are among the highest in the world. Although all administrative divisions were affected by child malnutrition there were important differences in the prevalences of the three anthropometric indicators. The prevalence of underweight ranged from 49.
