Outcome Measures
Primary Outcomes (1)
Proportion of eligible families screened who are willing and able to be randomised.
This is key to the determination of the likely success of a future, large-scale definitive randomised controlled trial (RCT).
Before birth
Secondary Outcomes (16)
Proportion of pregnant women approached who agree to be screened
Before birth
Proportion of families eligible on screening that cannot have a water softener installed (e.g. due to landlord or local authority refusal, technical (plumbing) reasons)
Before birth
Proportion of families randomised that withdraw due to infant ineligibility
Baseline (birth)
Proportion of families in intervention arm who found the intervention acceptable
End of follow up (6 months of age)
Proportion of participants in control arm that become exposed to softened water
End of follow up (6 months of age)
- +11 more secondary outcomes
Other Outcomes (8)
Transepidermal water loss (TEWL)
at birth, 4 weeks, 3 & 6 months oif age
Cutaneous cytokine profiles
at birth, 4 weeks, 3 & 6 months oif age
Natural moisturising factor (NMF) levels
at birth, 4 weeks, 3 & 6 months oif age
- +5 more other outcomes
Study Arms (2)
Domestic ion-exchange water softener
EXPERIMENTALThe intervention group will have a domestic ion-exchange water softener installed prior to birth.
Usual hard water supply
NO INTERVENTIONThe control group will receive their usual domestic water supply.
Interventions
Ion-exchange water softeners exchange calcium and magnesium, amongst other divalent cations, for monovalent sodium cations using a polystyrene resin. The sodium ions come from sodium chloride (common salt). The salt needs to be topped up every 3-4 weeks and sufficient quantities of block salt will be supplied to participants. The water softener used in this study does not require electricity and has two cylinders of resin which are used alternately. A control valve alternates the flow between the two cylinders and ensures a constant supply of regenerated resin. Ion-exchange water softeners typically reduce downstream water hardness to close to zero.
Eligibility Criteria
You may qualify if:
- Participant (i.e. the neonate) must have a parent or sibling with a history of doctor-diagnosed atopy (i.e. at least one of: eczema, asthma, hayfever)
- Mother aged ≥18 years of age at enrolment
- Baby \<36 weeks gestation at screening
- Informed consent from the mother on behalf of the participant
- Mother has the ability to understand English
- Live in a hard water area (\>250 mg/L Calcium Carbonate)
- Consent of landlord for installation on water softener (if appropriate)
- Occupy a property appropriate for installation of a water softener
You may not qualify if:
- Preterm birth (defined as birth prior to 37 weeks gestation)
- Significant inflammatory skin disease at birth not including seborrheic dermatitis ("cradle cap")
- Sibling (including twin) previously randomised to this trial. If multiple birth, the first child will be randomised into the trial.
- The child is to be fostered/adopted
- Any immunodeficiency disorder or severe genetic skin disorder
- Child has any other serious health issue which, at parent or investigator discretion, would make it difficult for the family to take part in the trial.
- Planned stays away from home for a continuous period of more than 2 weeks or a total of 1 month out of the 6 month follow up period
- Water softening or filtration device already installed
- Concurrent enrolment in any other skin-related intervention study
- Other medical condition that in the opinion of the CI could interfere with the conduct of the trial
