The 2007-2008 HarvestPlus Bangladesh Biofortified Rice Project Food Intake Dataset por International Food Policy Research Institute, University of California, Davis, International Centre for Diarrhoeal Disease Research, Bangladesh

“…Dietary information was collected primarily by direct observation and weighing of food preparation and consumption, including test weighing of milk intakes by breast-fed children. Height and weight were measured in all children and women, and in a subset of children, blood samples were collected and analyzed for concentrations of serum zinc and indicators of infection.…”

Household food expenditure, dietary diversity, and child nutrition in Nepal por Thapa, Ganesh B., Kumar, Anjani, Joshi, Pramod Kumar

“…We find that number of food groups consumed, monthly food expenditure, dietary diversity, and the expenditure shares on fruits and vegetables and animal protein have a positive impact on the expected height-for-age Z-scores. The dietary changes explain about 71 percent of the improvement in those scores between 1995 and 2011, underscoring the importance of dietary quantity, dietary diversity, and nutrient-dense food items for child nutrition outcomes.…”

Study of the determinants of chronic malnutrition in northern Nigeria: Quantitative evidence from the Nigeria Demographic and Health Surveys por Amare, Mulubrhan, Benson, Todd, Fadare, Olusegun, Oyeyemi, Motunrayo

“…A standard child-level regression based approach is used for the first part of the analysis using as the dependent variable whether the child aged 6 to 23 months is stunted (height-for-age z-score (HAZ) < -2.0). Separate models of the drivers of child stunting are developed for northern Nigeria (Northwest and Northeast geopolitical zones) in 2008 and in 2013 and for other areas of Nigeria in 2013. …”

Synopsis: Does market access mitigate the impact of seasonality on child growth? Panel data evidence from northern Ethiopia por Abay, Kibrewossen, Hirvonen, Kalle

“…In line with earlier studies, we document considerable seasonality in children’s age and height adjusted weights. While children located closer to local food markets are better nourished compared to their counterparts residing in more remote areas, their body weight is also subject to considerable seasonality. …”

Creating a child feeding index using the demographic and health surveys: an example from Latin America por Ruel, Marie T., Menon, Purnima

“…Data from the Demographic and Health Surveys (DHS) for five Latin American countries (seven data sets) were used to explore the feasibility of creating a composite feeding index and to examine the association between feeding practices and child height-for-age (HAZ). Urban/rural differences were also examined...The data sets used were Bolivia, 1994 and 1998; Colombia, 1995; Guatemala, 1995 and 1999; Nicaragua, 1998; and Peru, 1996...This work shows that the data available in DHS data sets can be used for a variety of purposes, including to (1) describe and study the distribution of specific feeding practices by geographic area, or other characteristics of interest such as maternal schooling or household socioeconomic status; (2) create a child feeding index to quantify and illustrate associations between child feeding practices and child outcomes, thereby serving as an advocacy tool; and (3) identify practices and vulnerable groups that could be targeted by programs and policies to improve child feeding practices and overall child health and nutrition. …”

The flight activity and infectivity of the major leafhopper vectors (Hemiptera: Cicadellidae) of rice tungro viruses in an irrigated rice area in the Philippines por Chancellor, T. C. B., Cook, A.G., Heong, K.L., Villareal, S.

“…Recilia dorsalis was the dominant species caught in suction traps at 0.75 m and 1.5 m and an upwardly-directed light trap at 4.0 m, whereas N. virescens was the most abundant species caught on sticky yellow traps at the height of the canopy. Infectivity tests on migrant leafhoppers caught in upwardly-directed light traps showed that N. virescens was the most common transmitter of rice tungro viruses. …”
