简要总结

Type of study: It is a community-based, randomized, single-blind, parallel-arm placebo-controlled  trial,  conducted  from   August 2024 to 31st December 2024.

Place of Study: Anganwadis in the field practice area of Urban Health Training Centre, Ulsoor of Shri Atal Bihari Vajpayee Medical College and Research Institute, Bengaluru will be enrolled.

Study Hypothesis: We hypothesize that zinc supplementation for 2 weeks will reduce the incidence of ARIs in subsequent months.

Inclusion Criteria: All under-5 age group children enrolled in Anganwadis of the urban field practice area and those who give consent

Exclusion Criteria: Children receiving zinc supplements in the past 3 months. Those who are severely malnourished, known immuno-deficient or on steroid therapy, Severely ill children requiring hospitalization.Children of families likely to migrate from the study area.

For sample size calculation, incidence of ARI was taken as 5.5 episodes (SD = 3.15) per child-year as per previous studies. Thus, for a 20% reduction in the incidence of ARI (a 0.05 and power 80%), we required 128 infants. Taking into account possible 5% attrition, the

Final sample size required is 134 children. 134 children will be divided into two groups consisting of 67 children each.

Methodology: A house-to-house survey will be done at the beginning of the study to identify and recruit the eligible infants enrolled in the anganwadis of UHTC area. The study purpose will be explained and an informed consent will be obtained from parents of all under-5 before being recruited. The recruitment will be done during first two weeks of June and followed by subsequent three months of follow-up. The eligible children will be randomized into two groups. One group receiving the intervention and the other group receiving placebo.

Intervention: The liquid preparation of multivitamin and zinc KIDICARE drops will be used. Age and weight prescribed dosage prescribed by pediatrician will be administered for 2 weeks. The parents were blinded to the treatment allocation till the end of follow-up period. The field investigator will administer the first dose of the intervention at the time of recruitment and will advise the mother to give daily to for the remaining 13 days.Subsequently visits will be made on the 7th and the 14th day to ensure compliance. In case the syrup had not been given regularly, a maximum of one week will be given to complete the dosages.Data will be collected for any possible side effects as reported by the caregivers during these visits. To ensure that the child did not receive additional doses of zinc, we will provide mothers with identity cards indicating the study title and that the child is participating in the study. These cards were to be produced whenever the child is taken to any medical practitioner.

Outcomes and Follow up: The primary outcome was the incidence of ARIs per child-year. Secondary outcomes included incidence of Acute Upper Respiratory Infections (AURI) and ALRI per child-year, duration of ARIs, and side effects.

AURI is diagnosed, if the child has cough or cold with or without fever. ALRI is diagnosed, if the child has symptoms of cough with difficult and/or rapid breathing or chest indrawing as informed by the caregiver. Duration is assessed as the number of days with ARIs and as mean number of days an ARI episode lasted. A baseline assessment will be done at the time of recruitment which included weight and height measurements using a Salter weighing Scale (up to 100 g) and a stadiometer, respectively. All the outcomes will be assessed by a trained field investigator based on the history given by caregiver.

Follow-up: for ARIs will begin at the 15th day post- intervention. Each child will be followed up fortnightly (± 3) days and the follow-up will continue till 3 months after completion of supplementation. At each followup, mother/caregiver will be asked about history  of ARIs during the previous 15 days. Recovery from an ARI episode will be considered when the last day of ARIs was followed by a 72-hour. ARI-free period. Subsequent episodes were considered to be new ARIs    episodes.
