Non-government organizations (NGOs) spend substantial time and resources collecting baseline data in order to plan and implement health interventions with marginalized populations. Typically interviews with households, often mothers, take over an hour, placing a burden on the respondents. Meanwhile, estimates of numerous health and social indicators in many countries already exist in publicly available datasets, such as the Demographic and Health Surveys (DHS) and the Multiple Indicator Cluster Surveys (MICS), and it is worth considering whether these could serve as estimates of baseline conditions.

Background: It is well established that insecticide-treated bed nets (ITNs), in particular long-lasting, insecticidal nets (LLINs), can be used as one of the primary interventions for effective malaria control. A consistent gap between net ownership and use has been observed, indicating that factors exist that prevent an owned mosquito net from being used. One approach used in the context of LLIN campaigns is a post-distribution, door-to-door visit of households with educational messages and to physically assist with hang-up of nets.

Background: The selection of food vehicles and fortification levels in food fortification programs may be made on the assumption of equitable intrahousehold distribution of food. There are concerns that biased intrahousehold distribution of food will make food-based interventions ineffective or unsafe.

Objective: To review available data documenting intrahousehold energy intake (as a proxy for food distribution) in low- and middle-income countries, and discuss the relevance for food fortification programs.

Northern Potosi is one of the poorest parts of Bolivia with the highest indicators of rural poverty, malnutrition and food insecurity in the Bolivian Andes. The objective of this research was to characterize the levels of malnutrition and describe infant feeding practices in Potosi, Bolivia and use this information to develop an effective, gender sensitive and culturally relevant intervention encouraging good infant feeding practices. Standard methods were used to collect anthropometric data.

Objective: To investigate whether children in households involved in a participatory agriculture and nutrition intervention had improved growth compared to children in matched comparable households and whether the level of involvement and length of time in the project had an effect on child growth.

Design: A prospective quasi-experimental study comparing baseline and follow-up data in 'intervention' villages with matched subjects in 'comparison' villages. Mixed model analyses were conducted on standardized child growth scores (weight- and height-for-age Z-scores), controlling for child age and testing for effects of length of time and intensity of village involvement in the intervention.

In October 2007, Madagascar conducted a nationwide integrated campaign to deliver measles vaccination, mebendazole, and vitamin A to children six months to five years of age. In 59 of the 111 districts, long-lasting insecticidal nets (LLINs) were delivered to children less than five years of age in combination with the other interventions. A community-based, cross-sectional survey assessed LLIN ownership and use six months post-campaign during the rainy season.

Background: In order to effectively promote exclusive breastfeeding, it is important to first understand who makes child-care and child-feeding decisions, and why those decisions are made; as in most parts of the world, exclusive breastfeeding until 6 months of age is uncommon in Malawi.

Objective: To characterize early infant foods in rural northern Malawi, who the decision-makers are, their motivation, and the consequences for child growth, in order to design a more effective program for improved child health and nutrition.

Methods: In a rural area of northern Malawi, 160 caregivers of children 6 to 48 months of age were asked to recall the child's age at introduction of 19 common early infant foods, who decided to introduce the food, and why.
