BACKGROUND Consumption of healthy diets that contribute with adequate amounts of fat and fatty acids is needed for children. Among Guatemalan children, there is little information about fat intakes. Therefore, the present study sought to assess intakes of dietary fats and examine food sources of those fats in Guatemalan children. METHODS The study(More)
OBJECTIVE To assess the within-subject and between-subject coefficients of variation (CV) of iron, zinc and copper concentrations in the milk of Guatemalan mothers. METHODS We performed a cross-sectional study in lactating women who had delivered a healthy infant 1 to 6 months previously in two low-income peri-urban areas (San Bartolome Milpas Altas and(More)
OBJECTIVE To assess the nutritional content and contribution to recommended nutrient intakes of the menu offerings in diverse daycare centers serving low-income urban families in Guatemala City. METHODS An observational study design was used to record all food and drink items offered to children attending four daycare centers on 5 different days of the(More)

While fortification of staple foods and condiments has gained enormous global traction, poor performance persists throughout many aspects of implementation, most notably around the critical element of regulatory monitoring, which is essential for ensuring foods meet national fortification standards. Where coverage of fortified foods is high, limited(More)
The paradigm of the first 1000 days of life, the period from conception to the second birthday, has been advanced as a critical window of opportunity to save a life and a child's future. Infancy and toddler life, through the first 24 months after birth, is a unique period during which human milk is recommended as either the exclusive source of nutrition (6(More)
BACKGROUND/OBJECTIVES In Guatemala, population-wide vitamin A fortification of table sugar has been operating for two decades. The objective of this study was to estimate the adequacy of vitamin A intakes in pregnant and lactating women from low-income, urban and rural communities. SUBJECTS/METHODS One or two previous-day dietary recalls were collected in(More)
OBJECTIVE Measurements of length at birth, or in the neonatal period, are challenging to obtain and often discounted for lack of validity. Hence, classical 'under-5' stunting rates have been derived from surveys on children from 6 to 59 months of age. Guatemala has a high prevalence of stunting (49.8%), but the age of onset of growth failure is not clearly(More)
OBJECTIVE Guatemala has the highest prevalence of stunting (54% of children under age 5 years) in the Americas and the fifth highest in the world. The aim of this study was to describe the stunting prevalence and the association with early feeding practices, morbidity patterns, and socioeconomic status (SES) in a sample of infants and toddlers from urban(More)
BACKGROUND The WHO recommends the introduction of nutritionally adequate, safe, and appropriate complementary foods at 6 mo of age, with continued breastfeeding up to 2 y and beyond. Suggested strategies to support continued breastfeeding often postulate optimal use of customary "family foods" and adequate amounts of indigenous foodstuffs and local foods.(More)
