MannaPack™ Potato Clinical Trial Wilna Oldewage-Theron PhD RD (SA) & Abdulkadir Egal PhD (PH)
OUTLINE OF PRESENTATION • Introduction • Background • Stakeholders • Methods • Results • Limitations • Conclusions • Recommendations
BACKGROUND: South Africa • 49.32 million (SSA 2009) • 40% live in poverty • (Cunnan & Maharaj, 2000:669, SA Govt, 2001) • 2.5% hungry (1.23 million people household food insecurity) (SSA 2009) • 20% of SA children stunted • 33.3% iron deficiency anaemia in children and women • 45.3% children at risk of zinc deficiency • 10% of children overweight (Labadarios et al., 2008) • 16.6% HIV and AIDS prevalence (WHO Stats, 2008)
INTRODUCTION • Diarrhea = one of the top killers of • children around the world • Solution = medication or oral rehydration fluids
INTRODUCTION • FMSC - new product, MannaPack™ Potato (MPP) to provide a “first food” in response to diarrhea • Dehydrated potato granules (resistant starches) • Lecithinated soy flour (protein source) • Gum arabic (soluble fiber) • Vitamins and minerals • Mild sweet potato flavoring • Reduce the impact of diarrhea and maintain • the gut during diarrhea and recovery.
MAIN AIM Overall purpose of the project was to document the actual impact and acceptability of MannaPack™ to reduce the impact and support resolution of the symptom of chronic and acute diarrhea.
SPECIFIC OBJECTIVES • Assess the acceptability of • MannaPack™ in a setting that provides care and treatment for children with diarrhea. • Assess the impact of MannaPack™ on • the quality and quantity of acute and chronic diarrhea in a community setting.
PROJECT METHODS • 1. Planning • Ethics approval (M080365) • Strategic participatory planning workshop with all stakeholders in South Africa (SA) • Two crèches in the Vaal region identified (control group) • SOS village for HIV/AIDS-affected orphans in Qwa-Qwa (experimental group). • Consent • Training of data enumerators and monitors
PROJECT METHODS • 2. Measurements • Diarrhea questionnaire - baseline + 6 weekly • Sensory questionnaire – baseline and end
PROJECT METHODS • 2. Measurements • Weight and height, handgrip, skin tenting • & nail blanching – baseline + 6 weeks
PROJECT METHODS 3. Intervention
QWA-QWA BACKGROUND • 5 people per household (hh) • 89.9% of caregivers unemployed • 67.4% of partners unemployed • 59.1% of hh < R 1000 (US$133) pm • 51.0% hh food insecurity
VAAL REGION BACKGROUND • 4.9 people per hh • 94.1% of caregivers unemployed • 80.1% of partners unemployed • 58.3% of hh < US$133 pm • 53.0% hh food insecurity
LIMITATIONS • Questionnaires not tested for SA but for Zimbabwe only although in the same region • Diarrhea not a public health problem in • SA – small sample size • 2010 World Cup
Beneficiary profile who completed the study • Children between the ages 2 to 13 years of age • Experimental group consisted of 29 girls and 32 boys with overall mean age of 6.2 years • Control group was 27 girls and 22 boys with overall mean age of 3.5 years • 2010 World Cup

CONCLUSIONS • MannaPackT consumption results indicated a minority consuming the product for the whole week. • A significant improvement was observed for underweight after the intervention. • Impact of the MannaPackTMon the nutritional status of the experimental group very clear. • This was not observed in the control group.
CONCLUSIONS • Incidence and severity of diarrhea significantly reduced in the experimental group as the study progressed. • Control group remained largely • unchanged. • MannaPackTM contributed to the • reduced incidence and prevalence of diarrhea in the experimental group.
ACCEPTABILITY RESULTS • Mashed potatoes not commonly consumed by the low-income groups in South Africa. • MannaPackTM not very acceptable at baseline. • Liked the MannaPackTM towards the end of the study.
RECOMMENDATIONS • MannaPackTM can be effectively used as a relief food in emergency situations where both diarrhea and/or acute food shortage exist. • Can complement the already successful commodities like CSB and WSB in the USAID title II programmes.
