Abstract

evelopment of phonotactic competency in various contexts of phonological constituents is a prerequisite of effective speech-language competency in the native language. This study aims to explore the phonotactic competency of Bengali-speaking children with and without speech-language impairment. A mixed-method approach exploring the nature of phonotactic competency and differences among those competencies was undertaken. A total of 80 children with typical development (20), autism spectrum disorder (20), down syndrome (20), and language delay (20) were recruited for this study. Typically developing participants statistically outperformed (p< .05) others regarding the production of ranges of syllable structure, clusters, and consonant types, while significant (p< .05) within and between group variability was accounted for in the other groups. Variations in the simplification processes of cluster production and error types across syllable positions were also observed. The findings of the study may facilitate the understanding of phonological development patterns of the study population, suggesting the inclusion of varied cluster simplification patterns to assess phonotactic competence.

Abstract

During 2011–2015, although national vaccination coverage exceeded 80%, rates among children in urban slums were much lower in Bangladesh. We identified factors associated with incomplete vaccination in slum areas. A case-control study was conducted in Dhaka and Chattogram slums from June 2016 to March 2017. Cases were children aged 12–18 months who missed one or more expanded program on immunization (EPI) recommended doses; controls were fully vaccinated children. Caregivers were interviewed, and adjusted odds ratios (AOR) with 95% confidence intervals (CI) were calculated for significant factors (p<0.05). Total of 603 cases and 1,029 controls were interviewed. Factors associated with incomplete vaccination included negative perceptions of vaccination (AOR 9.2, 95% CI 4.4–19.3), time barriers for caregivers (AOR 2.1, 95% CI 1.5–2.9), and poor health-seeking behavior for other health issues (AOR 2.2, 95% CI 1.6–2.9). Children with older siblings who had incomplete vaccination (AOR 3.4, 95% CI 2.4–4.8) and those with working mothers (AOR 1.7, 95% CI 1.1–2.6) were also at higher risk. Negative perceptions, time constraints, and working mothers contribute to incomplete immunization in slums. EPI should target vaccine hesitancy and extend service hours to improve coverage among working mothers.
