Exploratory study to guide the design of an emollients trial in Africa
This study, conducted in four African sites, will collect data to inform the design of a community based trial to evaluate whether massaging babies with emollients can reduce neonatal deaths.
Emollients are substances that soften and soothe the
skin such as oils and moisturisers. Skin can serve as an important
entry point for infections and applying
emollients to improve skin function is a potentially effective and affordable
means of reducing newborn infections. Hospital trials have already shown that
emollient use can reduce newborn infections and mortality in pre-term babies. (1-3)
Evidence is lacking about the effectivness of emollients on newborn infections in community settings and on full-term babies. The skin function of full-term babies may be compromised by maternal malnutrition during pregnancy. Home environments may also contain high levels of pathogens and family practices such as the removal of the Vernix, the application of contaminated substances to the skin and poor hand washing may increase infection risks. Community-based emollient trials are needed to establish if the positive results observed in hospitals can also be achieved in the home environment.
A community based trial is being conducted in rural India to evaluate the impact of improved oil and/or improved skin care practices on neonatal mortality

This study, funded by the Bill & Melinda Gates Foundation,
will collect data to inform the design of a community based trial to evaluate
whether massaging babies with emollients can reduce neonatal deaths. For this trial
to be feasible, acceptable, scalable and appropriately targetted, it must be
based on an understanding of the local context.
The study will review available literature and use qualitative
and quantitative research methods to understand current skin care and massage
practices, the acceptability of emollient use and potential distribution
channels for any future product. The impact of commonly used emollients on skin integrity and function will also be explored as not all emollients are
The study team will develop recommendations on how and where to test whether emollient therapy can reduce newborn mortality in Africa.

In order to understand the range of behaviours and
contexts related to emollient use and skin care in Africa, formative research
is required in a range of countries. The study will be conducted in four
African sites with high neonatal mortality and varied cultural,
socio-demographic and health system characteristics.
These sites are shown on the map and listed below
- Borno state in (North East) Nigeria
- Ekiti state in (South West) Nigeria
- West Arsi zone in Ethiopia
- Lindi and Mtwara districts in Tanzania
