Attitudes towards aging are multidimensional. It is often affected by the individual's social and cultural background. Valid and reliable tools across diverse cultures are important to assess the attitudes towards aging among older adults.
The Sinhala version of the Attitudes to Aging Questionnaire (AAQ) was cross-culturally validated following standard procedures. A validation study was conducted with a sample of 185 Sinhala-speaking older adults residing in residential care facility homes in the Colombo district. The Sinhala version of the AAQ was interviewer-administered along with the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire. Floor and ceiling effects were assessed for each AAQ subscale, considering effects present if ≥ 15% of participants achieved the lowest or highest possible score. Psychometric properties (Internal consistency reliability, convergent validity, known-group validity, and construct validity) were assessed by descriptive and inferential statistics using SPSS version 26. Statistical significance was set as 0.05.
The mean age of the sample was 72.3 ± 6.1 years. The majority (56.8%) of the participants were females. No significant floor or ceiling effects were observed for any subscale of AAQ. Internal consistency reliability, measured by Cronbach's alpha for psychosocial loss, psychological growth, and physical change subscales was 0.81, 0.77, and 0.74, respectively. Significant correlations were shown in Pearson's correlation between all the AAQ subscales and WHOQOL-BREF domains, indicating the convergent validity. Known-group validity showed that married individuals and individuals diagnosed with chronic disease scored significantly higher mean on all three subscales of AAQ. The exploratory factor analysis extracted three factors with 57.77% cumulative variance with exceptions from the original version. Twenty-two items loaded to any of the factors except items 21and 23.
The Sinhala version of the AAQ has sound psychometric characteristics and it is a culturally appropriate and reliable measure to assess attitudes towards aging among Sinhala-speaking older adults.

Background
The COVID-19 pandemic disrupted traditional learning, presenting unique challenges for nursing undergraduates due to the hands-on nature of their education. Assessing students’ readiness, usage of online platforms, and the barriers they face is crucial to evaluating the effectiveness and sustainability of online learning. This study aimed to investigate nursing undergraduates’ use of online learning facilities, readiness for online distance learning, and associated factors; to identify the barriers and challenges they faced; and to explore their perceived effectiveness with online distance learning during the COVID-19 pandemic.
Methods
This descriptive cross-sectional study was conducted among 137 nursing undergraduates in Sri Lanka. Data were collected using a pretested, validated study instrument, including students’ Online Learning Readiness Score (OLRS) distributed through Google Forms. The data were then analysed using descriptive statistics and multivariate analysis of variance.
Results
The study had a 91.3% response rate (
n
= 137), with a mean participant age of 24.18 (± 3.45) years. Nearly half (51.8%) accessed online classes via smartphones, and most (62.8%) used mobile data. Key challenges included mobility restrictions (85.4%), lack of face-to-face interaction (82.5%), heavy workloads (81%), household duties (79.6%), and poor internet connectivity (78.8%). The mean Online Learning Readiness Score (OLRS) was 13.95 (± 4.90), with higher scores in self-directed learning and motivation (3.44–3.63). MANOVA revealed a significant gender difference in OLRS (F = 3.932,
p
< 0.04; Wilks’ Lambda = 0.955; η² = 0.028), and significant differences in computer internet self-efficacy across academic years (F = 6.015,
p
< 0.001; Wilks’ Lambda = 0.808; η² = 0.119).
Conclusion
Nursing undergraduates faced several challenges to online learning during COVID-19, including mobility restrictions, low motivation, and poor connectivity. Despite moderate self-directed learning and motivation, overall readiness was low. Readiness varied by gender and academic year, indicating the need for targeted support to improve digital preparedness and engagement.

Introduction: The World Health Organization confirmed the COVID-19 epidemic situation as a public health emergency and is an emerging public health problem that has threatened millions of lives worldwide. Since COVID-19 has significantly affected the healthcare system globally, it is essential to update healthcare workers especially frontline nurses on the best practices for the proper management of the disease. The study aimed to assess Knowledge, Perceptions, and Practices regarding COVID-19 among frontline nurses at the National Institute of Infectious Diseases, National Hospital of Sri Lanka, and Base Hospital Mawanella in Sri Lanka. Methods: This cross-sectional study was conducted among 257 frontline nurses from main three hospitals in Sri Lanka from June 2020 to December 2021. A validated, pre-tested self-administered questionnaire was used for data collection. Kruskal Wallis test and Chi-square test were applied to find significant factors associated with good knowledge, using SPSS version 25. Results: The average age of the 257 participants was (31.8 ± 6.6) years and most (95%) of them were female. Of them, 79.4% had good knowledge, and the knowledge level of the nurses was significantly associated with their marital status (p=0.04) and their participation in the COVID-19 management workshop or lecture (p ≤0.001). There was a statistically significant median score difference between participants’ knowledge, and three hospitals (p<0.05). Conclusion: The findings demonstrated that the nurses had overall good knowledge, positive perception, and good practice on COVID-19. This study highlighted the factors influencing knowledge about COVID-19 that must be addressed in future education, awareness, and preparing the programs.

Education in medicine journal, 14, 2, 103 - 109
Nurse academics have faced many challenges in conducting face-to-face teaching and clinical training in the COVID-19 pandemic. Compared to the past, there was increased interest and usage in online education during the COVID-19 pandemic in nursing education. This short communication highlights the important aspects that nurse academics should consider while designing nursing curricula to face future pandemics based on the experiences of the COVID-19 pandemic. This short communication includes a critical analysis of experiences from previous pandemics and the lesson learned from the present pandemic of the use of blended learning approaches in nursing education. These would be effective in considering nursing curricula reforms. Four key themes related to blended learning were identified as blended learning, blended learning in nursing education, challenges related to blended learning and strengthening of the blended learning culture. In conclusion, the pandemic has taught nurse academics to navigate nursing curricula to suit current teaching and learning demands. Reforming curricula by incorporating blended learning would be timely.

Family Health Care Worker (FHCW) led educational interventions to have the potential to educate and promote community health. Improvement of women's knowledge of vulvovaginal discharge will promote health-seeking behaviours and prevent complications. This study was designed to evaluate the impact of an educational intervention (EI) on vulvovaginal discharge (VVD) for FHCWs in improving the knowledge and attitudes of females aged 18-49 years in selected communities in Sri Lanka. The EI was first implemented for the FHCWs. The effectiveness was assessed by a non-randomized controlled trial using an intervention group of n = 259 and a control group of n = 259 of females. Knowledge and attitudes on VVD were assessed using a pretested, validated interviewer-administered questionnaire at baseline and a posttest after six months of the intervention. The mean knowledge and attitude scores among the females in the intervention and control groups were similar at the baseline. At the post-test, the mean knowledge score among females in the intervention group was 44.96% (Standard Deviation (SD) ± 12.68) and the control group was 20.75% (SD ± 7.37) with a significant improvement (p < 0.001, Mean (M) = 23.68, 95.00% Confident Interval (CI) = 21.63 to 25.72) at the post-test. A significantly higher mean difference in attitudes scores (pre-test and post-test) was observed among the intervention group compared to the control group (p < 0.001, M = 2.90, 95.00% CI = 2.15 to 3.65). This highlights the importance of educational interventions to FHCW that in turn will enhance community health.

Objective: This study aimed to determine the prevalence of pre‐diabetes and diabetes among overweight and obese children in urban schools and factors associated with them, in Batticaloa District, Sri Lanka.
Methods: A school based cross‐sectional descriptive study was conducted to collect data on socio-demographic information, eating habits and physical activities, using a validated, pre-tested questionnaire. In addition, anthropometric measurements and glycosylated haemoglobin (HbA1c) test were performed. Multivariate logistic regression analyze was performed to identify the factors associated with glycemic status by using SPSS v23.
Results: Out of the 269 children recruited, 59% were obese. Prevalence of pre‐diabetes (HbA1c 5.7%–6.4%) and diabetes (HbA1c ≥ 6.5%) were 20.1% (95% CI 15.5%–25.4%) and 3.3% (95% CI 1.5%–6.3%) respectively. Multivariate regression shows that having a BMI of ≥ 27.5Kg/m2 (AOR=2.69), male gender (AOR=2.71) and ethnicity (AOR = 2.58) were found to be significant factors for higher HbA1c (≥5.7%).
Conclusions: Prevalence of prediabetes and diabetes among overweight and obese school children was high and mainly associated with body weight which is a modifiable risk factor. Lifestyle modifications focusing on weight reduction among overweight and obese school children especially boys, need to be carried out.

BACKGROUND: Social media has become a most inseparable part of young adults' lives with the rapid development of information and communication technology. The study aimed to assess the use of social media and its association with academic performance, well-being, and interpersonal relation of the health sciences undergraduates.
MATERIALS AND METHODS: A descriptive cross-sectional study was conducted among undergraduates in Faculty of Allied Health Sciences (n = 220), University of Sri Jayewardenepura, Sri Lanka. Data were collected using a pretested, self-administered questionnaire and analyzed using descriptive and inferential statistics.
RESULTS: The response rate was 79.5%. All undergraduates (n = 175) had social media accounts, and WhatsApp was the most frequently used social media site (96.0%), followed by Facebook (70.9%), mainly for communicating (85.1%), entertainment (83.4%), and online learning (65.7%). Most undergraduates (72.0%) spent 2-5 h daily on social media sites and followed social media 1-10 times per day (54.9%). The majority of them wished to use social media for academic purposes (94.9%), and the most preferred site for academic work was WhatsApp (65.1%). Most undergraduates' self-reported Grade Point Average (GPA) (46.3%) was < 2.9. There was a statistically significant association between the mean GPA and frequencies of using social media (P = 0.02) (not daily [3.3 +/- 0.3], 1-10 times a day [2.9 +/- 0.4], and more than 10 times a day [3 +/- 0.4]). Perceived social media addiction and duration of sleep (P = 0.02), activities of daily living (P = 0.004), and study time (P = 0.02) were found to be significantly associated.
CONCLUSIONS: Despite the undergraduates' willingness to use social media for academic purposes, the frequency of using social media had a significant influence on their academic performance. This highlights the importance of guidance on effective use of social media and social media addiction to improve undergraduates' academic performance, well-being, and interpersonal relationships.
