Maternal knowledge following nutrition behavior change communication is conditional upon both health workers’ knowledge and knowledge sharing efficacy in rural Haiti

submitted by: mduduzi
In the context of a food assistance program in rural Haiti, we developed measures of the effectiveness of community health worker (CHW)-delivered behavior change communication (BCC). We administered knowledge tests to 954 mothers and 38 CHWs to define 4 measures: CHW knowledge, maternal knowledge, knowledge-sharing efficacy (proportion of CHW knowledge shared), and shared correct knowledge between the CHWs and the mothers with whom they interacted. On the basis of the tests, CHWs had high...

Early participation in prenatal food supplementation program ameliorates the negative association of food insecurity with quality of maternal-infant interaction

submitted by: afrith
Food insecurity is detrimental to child development, yet little is known about the combined influence of food insecurity and nutritional interventions on child development in low-income countries. We proposed that women assigned to an early invitation time to start a prenatal food supplementation program could reduce the negative influence of food insecurity on maternal-infant interaction. A cohort of 180 mother-infant dyads were sampled (born between May and October 2003) from among 3267 in...

Multisector Intervention to Accelerate Reductions in Child Stunting: An Observational Study from 9 Sub-Saharan African Countries

submitted by: Alison Rose
Background: In sub-Saharan Africa, ~40% of children <5 y old are stunted, with levels that have remained largely unchanged over the past 2 decades. Although the complex determinants of undernutrition are well recognized, few studies have evaluated strategies that combine nutrition-specific, health-based approaches with food system– and livelihood-based interventions. Objective: We examined changes in childhood stunting and its determinants after 3 y of exposure to an integrated,...

Projected effects of tobacco smoking on worldwide tuberculosis control: mathematical modelling analysis

submitted by: ucsfnews
BMJ 2011; 343:d5506 http://bmj.com/cgi/content/full/bmj.d5506 http://www.ncbi.nlm.nih.gov/pubmed/21972295 ABSTRACT We constructed a state transition, compartmental, mathematical model of tuberculosis epidemics to estimate the impact of alternative future smoking trends on tuberculosis control. We projected tuberculosis incidence, prevalence, and mortality in each World Health Organization region from 2010 to 2050, and incorporated changing trends in smoking, case detection,...

The Leveraged Freedom Chair: a developing country wheelchair

submitted by: awinter@mit.edu
The purpose of the Leveraged Freedom Chair (LFC) project is to create a mobility aid specifically for developing countries. Conventional western-styled wheelchairs are nearly impossible to propel on the sandy roads and muddy walking paths frequently encountered in the developing world. The LFC has a variable mechanical advantage lever drivetrain that enables its user to travel 10-20% faster on tarmac than a conventional wheelchair, and off road like no other mobility aid available. The user...

For now, for the full text and figures, please refer to the paper available at: http://dx.doi.org/10.1371/journal.pmed.0050124 Abstract: In sub-Saharan Africa (SSA), communicable diseases, particularly HIV/AIDS, tuberculosis (TB), and malaria, are still responsible for the greatest burden of morbidity and mortality [1]. However, non-communicable diseases...
