Caregiver perceptions of nutrition interventions in infants and children under 24 months of age: a systematic review.

OBJECTIVE

Efficacy studies show early nutrition interventions improving infant nutrition status, but understanding caregiver acceptability is required for implementation of such interventions. This systematic review examines caregivers' perceptions of nutrition interventions in young children.

DESIGN

We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL and PsychINFO from date of online journal inception through December 2020. Interventions included oral (powder/liquid/tablet) and/or intravenous supplementation, food fortification and nutrition counselling. Inclusion criteria included primary research, data presented on caregiver perception and studies published in English. Quality assessment was performed using the Critical Appraisal Skills Programme tool. Studies underwent narrative synthesis using inductive thematic analysis.

SETTING

No restriction.

PARTICIPANTS

Caregivers of children under 24 months of age.

RESULTS

Of 11 798 records identified, thirty-seven publications were included. Interventions included oral supplementation, food fortification and nutrition counselling. Caregivers included mothers (83 %), fathers, grandparents and aunts. Perceptions were gathered through individual interviews, focus group discussions, questionnaires, surveys and ratings. Totally, 89 % of studies noted high acceptability ( 33 most notably increased appetite ( 17). In total, 57 % of studies ( 21) cited low acceptability, commonly from side effects ( 13) such as gastrointestinal issues, appetite loss and stained teeth.

CONCLUSIONS

Positive perceptions and enthusiasm for interventions were frequently reported. Key to implementation was the increased appetite noted by caregivers. A substantial proportion of studies reported negative perceptions, mainly due to side effects. In future interventions, mitigation and education around common side effects are crucial for acceptability. Understanding both positive and negative caregiver perceptions is important for informing future nutrition interventions and strengthening sustainability and implementation.
