Item Effects of indoor air pollution on the development of children under five years of age in Sri Lanka(MDPI, 2022) Ranathunga, N.; Perera, P.; Nandasena, S.; Sathiakumar, N.; Kasturiratne, A.; Wickremasinghe, R.Air pollution is a multifaceted environmental toxin affecting the Central Nervous System (CNS) through diverse pathways. The CNS of young children is particularly susceptible to the detrimental effects of toxins, as brain development continues postnatally with the formation of interneuronal connections, glial cell proliferation and myelination of axons. Indoor air pollution (IAP) from solid fuel combustion is more harmful than outdoor air pollution. Numerous air pollutants hazardous to health are released during the burning of unprocessed biomass. The primary source of fuel in Sri Lanka for cooking is biomass, mainly wood. In this study, we evaluated the influence of IAP resulting from biomass combustion on the neurodevelopment of children. In a cohort of children under five years living in a semi-urban area of Sri Lanka, neurodevelopment was assessed using Denver II developmental screening test. Air quality levels were measured (Carbon Monoxide (CO) and Particulate Matter 2.5 (PM2.5)) in a subsample. There were significantly high levels of CO and PM2.5 in the ambient air of households using biomass as the primary fuel for cooking. Children living in these households had a significantly higher number of children with ‘suspect’ developmental assessment scores in the language, social behavior and play and gross motor development domains.Item The Effectiveness of using multi-sensory children’s stories on vocabulary development in young deaf and hard-of-hearing children(Taylor & Francis, 2021) Hettiarachchi, S.; Ranaweera, M.; Disanayake, H.M.L.N.ABSTRACT: Young deaf and hard-of-hearing children enrolling in school in Sri Lanka often display language delay due to limited amplification and limited language stimulation. The scarcity of speech and language therapy support within the educational context at present necessitates a rethink of service-delivery models to reach more children. Multi-sensory stimuli and traditional children’s stories have been used in speech and language therapy to promote vocabulary development in children experiencing language-learning difficulties. Fifteen deaf or hard-of-hearing children from three different educational contexts were offered a three week “Katha malu” multi-sensory children’s story programme through the class teacher. The programme focused on developing receptive and expressive vocabulary of a set of 30 target words. The programme was offered using a combination of Sri Lankan Sign Language and Spoken Sinhala. The participants' receptive and expressive vocabulary knowledge on the target words was assessed using a specially devised picture-based vocabulary assessment pre- and post-intervention. The results show positive gains at both group and individual levels on receptive and expressive vocabulary skills. There was a positive effect of familiarity with the story with the overall vocabulary gains more prominent for the older, more traditional story. The findings of this study highlight the possibility of offering access to language stimulation programmes at classroom-level facilitated by the class teacher, under the guidance of a speech and language therapist.
