CDC Kerala 17: Early Detection of Developmental Delay / Disability Among Children Below 3 y in Kerala - A Cross Sectional Survey

Abstract

Objective

To conduct a community survey to understand the prevalence and type of developmental delay / disability among a representative state wide community sample of children below 3 y.

Methods

A state wide community based cross sectional survey was done with the help of the Integrated Child Development Services (ICDS) network in Kerala after giving one day training program at Child Development Centre (CDC), for one randomly selected anganwadi worker in each of the panchayath/municipal ward, from all districts of Kerala, to equip them to screen all children below 3 y in their anganwadi areas, using simple community screening tools like Trivandrum Developmental Screening Chart (TDSC) 0–3 and Language Evaluation Scale Trivandrum (LEST) 0–3. Those children with one or more item delay in TDSC or LEST were called to the developmental evaluation camps held at ICDS block level and trained pediatrician/medical officer re-evaluated the children with developmental delay.

Results

A total of 32,664 children below 3 y were screened across the state and overall 2.5 % prevalence of developmental delay was observed using TDSC and 2.8 % using LEST 0–3 y and 3.4 % using TDSC and/or LEST positive. Out of the total 1,110 children clinically evaluated by a trained pediatrician, 69.3 % children had developmental delay, 14.3 % speech delay, 5.7 % global delay, 5.3 % gross motor delay and 3.6 % suspected of hearing impairment.

Conclusions

The study results showing 3.4 % prevalence of developmental delay using TDSC and/or LEST by trained anganwadi workers or ASHA workers could be replicated in other states in India, under Rashtria Bal Swasthya Kariyakram.
