Screen time of children with speech delay: a cross-sectional study in a tertiary center in Kuantan, Malaysia.

BACKGROUND: Studies suggest excessive screen time (use of smartphones, televisions, computers and/or video games) is linked to speech and language delay. This study explored the sociodemographic characteristics of children with speech delay in Kuantan, Malaysia, and the association of screen time with speech and other developmental delays. METHODS: This cross-sectional study was conducted between July and November 2019 at the child psychiatry and speech therapy clinics, at Kuantan Hospital, Pahang, Malaysia. Parents of children with speech delay aged <72 months provided information on their children's and their own screen times. Speech and other developmental skills were assessed using the Schedule of Growing Skills II with scores reported as developmental quotient (DQ) level. RESULTS: The study included 91 children (67 boys, 24 girls) of whom 54.9% had primary speech delay and 45.1% had neurodevelopmental disorders; their mean age was 39.9 ± 11.52 months. The children's mean screen time was 2.26 ± 1.98 h daily, with 36.3% exceeding 2 h. Higher children's screen time was moderately correlated with higher parental screen time (rs = 0.479, P < 0.01). Household income was positively correlated with screen times of the children and the parents (rs = 0.243, P = 0.02 and rs = 0.390, p < 0.01, respectively). Parents who intended to reduce their children's screen time reported higher screen time in their children (t(89) = 2.322, P = 0.023). Children's age was positively correlated with the number of types of screen media (rs = 0.225, P = 0.032). The mean speech DQ was 54.76 ± 24.06%. Lower speech DQ was associated with lower DQs in other skills (P < 0.01). No significant correlation was shown between children's and parents' screen time with DQs of speech and other skills (P > 0.05). CONCLUSION: The correlation between parent and child screen time provides an opportunity for possible intervention, where necessary. Larger studies are required to examine this correlation further.

Five winters of pneumococcal serotype replacement in UK carriage following PCV introduction.

The seven-valent pneumococcal conjugate vaccine (PCV7) was added to the UK national immunisation programme in September 2006. PCV13 replaced PCV7 in April 2010. As carriage precedes disease cases this study collected carried pneumococci from children each winter from 2006/7 to 2010/11 over PCV introduction. Conventional microbiology and whole genome sequencing were utilised to characterise pneumococcal strains. Overall prevalence of pneumococcal carriage remained stable. Vaccine serotypes (VT) decreased (p<0.0001) with concomitant increases in non-vaccine serotypes (NVT). In winter 2010/11 only one isolate of PCV7 VT was observed (6B). PCV13 unique VTs decreased between winters immediately preceding and following PCV13 introduction (p=0.04). Significant decreases for VTs 6B, 19F, 23F (PCV7) and 6A (PCV13) and increases for NVT 21, 23B, 33F and 35F were detected. The serotype replacement was accompanied by parallel changes in genotype prevalence for associated sequence types with clonal expansion contributing to replacement. By winter 2010/11, serotype coverage of PCV7 and PCV13 was 1% and 11% respectively. VT replacement was observed for PCV7 and PCV13 serotypes. Conjugate vaccine design and use requires continuous monitoring and revision.
