RESUMEN
OBJECTIVE: To determine the effects of lipid-based nutrient supplements (LNS) on children's Hb, linear growth and development, compared with supplementation with micronutrient powder (MNP). DESIGN: The study was a two-arm parallel-group randomized controlled trial, where participants received either LNS or MNP for daily consumption during 6 months. Supplements were delivered by staff at government-run health centres. Hb, anthropometric, motor development, language development and problem-solving indicators were measured by trained research assistants when children were 12 months of age. SETTING: The study was conducted in five rural districts in the Province of Ambo in the Department of Huánuco, Peru. SUBJECTS: We enrolled 6-month-old children (n 422) at nineteen health centres. RESULTS: Children who received LNS had a higher mean Hb concentration and lower odds of anaemia than those who received MNP. No significant differences in height-for-age, weight-for-height or weight-for-age Z-score, or stunting and underweight prevalence, were observed. Provision of LNS was associated with a higher pre-verbal language (gestures) score, but such effect lost significance after adjustment for covariates. Children in the LNS group had higher problem-solving task scores and increased odds of achieving this cognitive task than children in the MNP group. No significant differences were observed on receptive language or gross motor development. CONCLUSIONS: LNS between 6 and 12 months of age increased Hb concentration, reduced anaemia and improved cognitive development in children, but showed no effects on anthropometric indicators, motor or language development.

Overweight and obesity in children and adolescents represent a serious public health problem in Peru, with high costs for society that require the implementation of a set of public policies directed toward its control. Thus, interventions have been proposed as the regulation of advertising of unhealthy foods, self-regulation, the implementation of kiosks healthy and nutritional labeling. From the analysis of the problem of overweight and obesity in children and adolescents in Peru, this article is a narrative review of such interventions.

El sobrepeso y la obesidad en niños y adolescentes representa un serio problema de salud pública en el Perú, con elevados costos para la sociedad, esto hace necesaria la implementación de un conjunto de políticas públicas dirigidas hacia el control de dicho inconveniente. Así, se han propuesto intervenciones como la regulación de la publicidad de alimentos no saludables, su autorregulación, la implementación de quioscos saludables y el etiquetado nutricional. Desde el análisis de la problemática del sobrepeso y obesidad en niños y adolescentes en el Perú, el presente artículo hace una revisión narrativa de dichas intervenciones.
