Brief Summary:
This a cluster randomised controlled trial (cRCT) to evaluate the effect of a novel food hygiene intervention on infant health.

Condition or disease Intervention/treatment Phase
Enteric Infections Diarrhea Behavioral: Safe Start Behavioral: Active Control Not Applicable

Detailed Description:

Enteric infections remain a major threat to child health and development in many low and middle-income countries. Globally, diarrhoeal disease - a key health consequence of enteric infection - is ranked as the fourth leading cause of disability globally, after ischaemic heart disease, lower respiratory tract infections and strokes. Diarrhoeal disease persists as the second leading cause of child deaths in the world, and in sub-Saharan Africa is the leading cause of child deaths.

Public health efforts to address diarrhoeal disease have largely focused on improving access to safe drinking water and sanitation and promoting hand washing with soap to address faecal-oral routes of transmission. These interventions though may not effectively address all exposure pathways during early life, when young children are most susceptible to infection and the diarrhoeal disease burden is greatest. One potentially important exposure pathway is infant food which recent studies conducted in low income, high burden settings suggest may be highly contaminated and may be amenable to simple behaviour change interventions.

The Safe Start trial will evaluate the effect of a novel food hygiene intervention on infant health implemented in low income urban neighbourhoods of Kisumu, Kenya. The intervention is designed to target early childhood exposure to enteric pathogens through contaminated food and was developed through an earlier phase of formative behavioural and microbiological research. The intervention will target infant caregivers and be delivered through the Community Health Volunteer (CHV) health extension system. Four key behaviours will be addressed by the intervention:

  1. Safe hand hygiene: handwashing with soap before infant food preparation and feeding
  2. Safe food preparation: bringing all infant food to the boil before feeding, including when reheating
  3. Safe storage of food: storing all infant food in sealed containers
  4. Safe feeding: reserving specific feeding utensils for the infant and keeping these separate and clean

A cluster randomized controlled trial (cRCT) design will be used to evaluate the intervention with each CHV catchment area forming one cluster. The outcomes of interest for this study are as follows: (1) the prevalence of enteric infections among infants at 37 weeks of age (primary); (2) the longitudinal prevalence of diarrhoea between 22-37 weeks of age (primary); and (3) incidence of all-cause mortality between 22-37 weeks of age. Infants will be recruited on a rolling basis at 22 weeks of age (+/- 1 week), and data and/or samples collected at 3 points: baseline at 22 weeks of age (+/- 1 week); midline at 33 weeks of age (+/- 1 week); and endline at 37 weeks of age (+/- 1 week). Stool samples will be collected at baseline and endline and analysed for 23 genetic sequences indicating the presence of enteric pathogens known to cause childhood diarrhoea in low income, high burden settings.

Actual Enrollment : 880 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Masking Description: Outcome assessors are not informed of allocation but would likely infer this from the presence of highly visible domestic products that are part of the intervention. Lab technicians and data analysts are masked to allocation status.

Arm Intervention/treatment
Experimental: Intervention
Participant households will receive 4 visits by health extension workers delivering intervention
Behavioral: Safe Start
Participant households will receive four visits over a 10 week period from health extension workers promoting safe food preparation, storage and feeding, and will be provided with products to support these practices (a bowl, spoon, cup, hand washing station, liquid soap dispenser).

Active Comparator: Control
Participant households will receive 4 visits by health extension workers delivering standard care
Behavioral: Active Control
Participant households will receive 4 visits by health extension workers delivering standard care




Primary Outcome Measures :
  1. Enteric infection prevalence [ Time Frame: At 37 weeks of age (+/- 1 week) ]
    Enteric infections are defined as the presence of enteric pathogens in stool as indicated by 1 or more of these 23 genetic sequences: Shigella/EIEC virulence plasmid, EAEC_aaic, EAEC_aata, EPEC_eae, EPEC_bfpa, ETEC_LT, ETEC_STp_STh, EHEC Escherichia coli 0157, Aeromonas, Vibrio cholerae, Campylobacter jejuni/C. coli, Clostridium difficile, and Salmonella enterica), Adenovirus 40/41, Adenovirus Hexon, Norovirus GI, Norovirus GII, and Rotavirus and broad reactive Cryptosporidium_18s, C. hominus, C. parvum, and Giardia assemblages A & B.

  2. Diarrhoeal disease longitudinal prevalence [ Time Frame: Between 22 and 37 weeks of age (+/- 1 week) ]
    Longitudinal prevalence is defined by days with diarrhoea during follow-up with diarrhoea defined according to WHO definition (3 or more loose or liquid stools passed within 24 hours)


Other Outcome Measures:
  1. All-cause mortality incidence [ Time Frame: Between 22 and 37 weeks of age (+/- 1 week) ]
    Deaths occurring during follow-up due to any cause
