Prevalence and Correlates of Vitamin D Deficiency Among Children and Adolescents From a Nationally Representative Survey in India

Objective: To evaluate the prevalence of vitamin D deficiency (VDD) and its correlates among apparently healthy children and adolescents. Methods: We carried out a secondary analysis of data of Comprehensive National Nutrition Survey 2016-18 to analyze the pre-valence and predictors of VDD among Indian children and adolescents. Results: The over-all prevalence of VDD in preschool children (1-4 years), school age (5-9 years) children, and adolescents (10-19 years) was 13.7%, 18.2%, and 23.9%, respectively. Age, living in urban area, and winter season were significantly associated with VDD. Vegetarian diet and high-income households were the main risk factors observed in 5-19 years age category. Female sex and less than three hour of physical activity/week were independent risk factors among adolescents. Conclusion: The prevalence and determinants of VDD across different age-groups are reported, and these should be interpreted and addressed to decrease the burden of VDD in India.

Valor monetario de la leche materna en Bolivia / The monetary value of breast milk in Bolivia

Objetivos. Estimar el volumen de leche materna consumido por los niños bolivianos de < 36 meses de edad y el valor monetario de la sustitución de dicho volumen de leche materna con sucedáneos comerciales. Métodos. Para el análisis se tuvieron en cuenta la distribución de la población infantil por grupos de edad, la prevalencia de las diferentes prácticas de lactancia materna (exclusiva o parcial) en cada grupo de edad, el volumen promedio de leche materna consumido por los lactantes de un grupo de edad determinado y el costo de la producción y sustitución de la leche materna. Resultados. Los lactantes bolivianos consumen anualmente más de 161 millones de litros de leche materna, lo que representa un volumen promedio de 573 mL/día por cada lactante menor de un año. El valor monetario de la leche materna consumida por los lactantes bolivianos asciende a US$ 274 millones anuales. El costo promedio de sustituir la leche materna con sucedáneos comerciales en un lactante amamantado adecuadamente el primer año de vida asciende a US$ 407. Discusión. Para que la formulación y consolidación de políticas y programas de protección, promoción y apoyo a la lactancia materna sean una realidad, los líderes políticos de Bolivia han de tomar conciencia del enorme valor monetario de la leche materna

Objective. To estimate the volume of breast milk consumed by Bolivian children under 36 months of age, and the monetary value of replacing that volume of breast milk with commercial substitutes. Methods. The analysis took into account the distribution of the infant population by age groups, the prevalence of breast-feeding practices (exclusive or partial) in every age group, the average volume of breast milk consumed by the infants of a given age group, and the cost of breast milk production and replacement. Results. Bolivian infants annually consume more than 161 million liters of breast milk, which represents an average volume of 573 mL/day per infant under 1 year of age. The monetary value of breast milk consumed by the Bolivian infants amounts to US$ 274 million annually. The average cost of replacing breast milk with commercial substitutes for an infant adequately breast-fed for the first year of life would be US$ 407. Discussion. For the formulation and consolidation of policies and programs to protect, promote, and support breast-feeding to become a reality, it is necessary that the political leaders of Bolivia be aware of the enormous monetary value of breast milk
