A Community-Based Positive Deviance/Hearth Infant and Young Child Nutrition Intervention in Ecuador Improved Diet and Reduced Underweight.

OBJECTIVE: Underweight and stunting are serious problems in Ecuador that require interventions in the first 2 years of life. The researchers assessed the effectiveness of a Positive Deviance (PD)/Hearth community-based intervention using local foods to improve infant and young children's nutrition. DESIGN: A quasi-experimental nonrandomized study was conducted between March and October, 2009. SETTING: The intervention and study were implemented in the Ecuadorian highlands provinces of Chimborazo and Tungurahua. PARTICIPANTS: Eighty mother-child pairs in 6 intervention communities and 184 mother-child pairs in 9 comparison communities. INTERVENTION: Mothers met in participatory peer-led PD/Hearth cooking and nutrition education sessions for 12 days. MAIN OUTCOME MEASURES: Dietary intake and nutritional status were collected at baseline and 6-month follow-up. ANALYSIS: Multiple linear and logistic regression were used for growth outcomes, and ANCOVA for mean dietary intakes. RESULTS: Mothers in the intervention were 1.3-5.7 times more likely to feed their children the promoted foods (P < .05). Children in the intervention consumed a higher percentage of recommended intakes for iron, zinc, vitamin A, protein, and energy (P < .05) at follow-up and had improvements in weight-for-age z-score (ß = .17; 95% confidence interval, 0.01-0.31). Likelihood of underweight was reduced for children in the intervention (odds ratio = 0.36; 95% confidence interval, 0.13-0.96) CONCLUSIONS AND IMPLICATIONS: The PD/Hearth interventions support mothers to improve infant and young children's nutrition practices and reduce underweight.

Infant and young child feeding practices and stunting in two highland provinces in Ecuador.

The first two years of life are critical for growth and development. Little is known about infant and young child feeding (IYCF) practices in the Ecuadorian highlands and how they contribute to stunting. With the objective of understanding nutritional status and the influencing factors to design an intervention, we assessed the nutritional status of 293 infants and children between 0 and 24 months of age, living in 14 communities in the provinces of Tungurahua and Chimborazo using a cross-sectional study design. We used the WHO IYCF indicators to assess feeding practices; estimated dietary intake with 24-h recalls; and identified nutritious local foods by food frequency questionnaires. Multiple regression modelling was performed to identify correlates of nutritional status. Stunting was found in 56.2% of children. Mean protein, vitamin A and vitamin C intakes were above recommendations for all ages. Only infants 6.0 to 8.9 months of age and non-breastfed children 12-23.9 months of age consumed energy intakes below recommendations. Younger age groups had below recommended intakes for iron and calcium. While mean complementary food densities met recommendations for protein, vitamin A, vitamin C and energy, those for zinc, iron and calcium were lower than recommended. Older age, respiratory infections and being male were predictors of lower HAZ, whereas early initiation of breastfeeding, higher socioeconomic status, consumption of iron-rich foods and higher dietary protein density were protective. Interventions that promote and support optimal breastfeeding practices and enable increased consumption of nutritious local foods have potential to contribute to reducing stunting in this vulnerable population. © 2016 John Wiley & Sons Ltd.

Mothers' groups enrich diet and culture through promoting traditional Quichua foods.

Indigenous Peoples in Latin America bear a disproportionate burden of undernutrition, yet traditional foods, including wild leafy greens, can contribute nutritional value to diets. As part of a community nutrition intervention using local foods in highland Tungurahua, Ecuador, mothers' groups promoted the consumption of wild leafy greens through community cooking clubs and recipe competitions at local fairs. The objective was to assess the social, cultural, and nutritional potential of a mothers' club intervention that promoted 2 indigenous greens (stinging nettle/Urtica dioica L. and round-leaved dock/Rumex obtusifolius L.) into children's diets. Key informant interviews and focus groups were conducted with 54 mothers and 16 elders to identify perceptions of the intervention and traditional foods. Social and cultural dimensions were identified through content analysis. The nutritional contribution of the leafy greens was estimated through semiquantitative food frequency questionnaires conducted with 160 participant mothers and 98 mothers living in comparison communities who had not been exposed to the intervention. The use of local foods generated pride for mothers and elders. Nonfood uses of the nettle proved an initial barrier to acceptance; however, peer support within mothers' groups enabled increased consumption. The greens were estimated to contribute an additional 8% vitamin A, 7% iron, 12% vitamin C, and 27% folate to children's recommended dietary intakes. By promoting wild leafy greens, mothers' groups improved food security and the cultural and nutritional value of their diets. Additionally, mothers' cooking clubs increased self-efficacy and cultural identity for Quichua women, offering a highly acceptable nutrition intervention model.

Adjustments for weighing clothed babies at high altitude or in cold climates.

Public health nutritionists rely on anthropometry for nutritional assessment, program planning, and evaluation. Children are usually heavily clothed at high altitudes and in cold climates. Failing to adjust for clothing weight could underestimate malnutrition prevalence. The objective of this paper is to validate an adjustment process for estimating clothing weight and quantify potential misclassification error. In March and September 2009, 293 and 272 children under 2 years of age, respectively, were measured for weight and length in 14 highlands communities in Ecuador. Weight-for-age z-scores (WAZ) and weight-for-height z-scores (WHZ) were compared using clothing-unadjusted weights and two types of clothing-adjusted weights: individual clothing-weights and population-mean clothing-weights. Modelling showed up to 24% of children's nutritional status and degree of malnutrition were misclassified for WAZ, and 13% for WHZ, when clothing was not taken into account in this cold climate. Compared with the more time-intensive individual clothing-weight adjustment, the population-mean clothing-weight adjustments had high specificity and sensitivity for WAZ. In cold climates, adjusting for population mean clothing weight provides a better estimate of the prevalence of malnutrition to inform appropriate program decisions for addressing underweight. An individual clothing weight adjustment may also be essential to classify a specific child's nutritional status when acute malnutrition is a concern.

Infant and young child feeding in the Peruvian Amazon: the need to promote exclusive breastfeeding and nutrient-dense traditional complementary foods.

The study objective was to understand the role of traditional Awajún foods in dietary quality and the potential impacts on growth of Awajún infants and young children 0-23 months of age. Research took place in April and May of 2004, along the Cenepa River in six Awajún communities. Anthropometry estimated nutritional status for 32 infants (0-23 months). Repeat dietary recalls and infant feeding histories were completed with 32 mothers. Adequacy of the complementary foods was compared with World Health Organization guidelines. Anthropometry indicated a high prevalence of stunting (39.4% of infants and young children), with nutritional status declining with age. Half of the Awajún mothers practised exclusive breastfeeding. Dietary recalls and infant food histories suggested that many of the infants were getting adequate nutrition from complementary foods and breastfeeding; however, there was variation in breastfeeding and complementary feeding practices among the mothers. Complementary feeding for young children 12-23 months generally met nutrient recommendations, but mean intakes for iron, zinc, calcium and vitamin A were inadequate in infants 6-11 months. Traditional foods provided 85% of energy and were more nutrient dense than market foods. Appropriate infant and complementary feeding was found among some women; however, given the range of feeding practices and introduction of market foods, health promotion targeting infant and young child feeding is warranted.
