Securing Human Capital Towards Equity: Social Determinants and Protective Factors of Speech-Language Delay in Malaysia

Abstract

Speech and language delay (SLD) is a critical public health concern that threatens long-term human capital and social equity. This study investigates the significant gap in localised clinical evidence regarding the socio-structural determinants and protective factors of SLD in diverse, multilingual settings. Utilising a cross-sectional methodology, the research analysed multisource secondary data from 320 paediatric clinical records at a major Malaysian referral centre. Data collected included sociodemographic characteristics, language exposure, medical history, and healthcare-related barriers. Results indicate a high clinical prevalence of SLD at 51.9%, significantly exceeding national estimates. Multilingual backgrounds (AOR = 2.13) and parental barriers to follow-up care (AOR = 3.02) were associated with significantly higher odds of SLD. Conversely, older age and the presence of an underlying diagnosed condition were identified as significant protective factors. These findings imply that securing human capital requires an equitable approach to healthcare through culturally sensitive screening and the removal of logistical barriers. Aligning with sustainable development goals, this study advocates for integrated public health strategies to ensure inclusive developmental outcomes for all children.
