Problem: The novel coronavirus disease 2019 (COVID-19) pandemic adversely affected the preparation of Malaysia’s National Health and Morbidity Survey for 2020 because conducting it would expose data collectors and participants to an increased risk of infection.
Context: The survey is nationally representative and community based and is conducted by the Institute for Public Health, part of the National Institutes of Health, to generate health-related evidence and to support the Malaysian Ministry of Health in policymaking. Its planned scope for 2020 was the seroprevalence of communicable diseases such as hepatitis B and C.
Action: Additional components were added to the survey to increase its usefulness, including COVID-19 seroprevalence and facial anthropometric studies to ensure respirator fit. The survey’s scale was reduced, and data collection was changed from including only face-to-face interviews to mainly self-administered and telephone interviews. The transmission risk to participants was reduced by screening data collectors before the survey and fortnightly thereafter, using standard droplet and contact precautions, ensuring proper training and monitoring of data collectors, and implementing other administrative infection prevention measures.
Outcome: Data were collected from 7 August to 11 October 2020, with 5957 participants recruited. Only 4 out of 12 components of the survey were conducted via face-to-face interview. No COVID-19 cases were reported among data collectors and participants. All participants were given their hepatitis and COVID-19 laboratory test results; 73 participants with hepatitis B and 14 with hepatitis C who had been previously undiagnosed were referred for further case management.
Discussion: Preparing and conducting the National Health and Morbidity Survey during the COVID-19 pandemic required careful consideration of the risks and benefits, multiple infection prevention measures, strong leadership and strong stakeholder support to ensure there were no adverse events.

Introduction:
In Malaysia, the adolescent health studies conducted in 2012 and 2017 revealed an increasing trend of adolescent health risk behaviours and protective factors. This current study aims to determine health risk behaviours and protective factors among adolescents in the country.
Methods:
The current nationwide cross-sectional study of Malaysian secondary school students used multistage stratified sampling to select 240 nationally representative schools. This study was conducted from June to July 2022 among the students in forms 1, 2, 3, 4, and 5 in all Malaysian states by 34 data collection teams. A validated self-administered questionnaire was used, similar to those used in the NHMS 2012 and NHMS 2017. The quality control was done twice, once at the field level and once at the central level. Sample weighting and analysis were conducted using SPSS statistical software version 28.0.
Results:
A total of 239 schools out of 240 schools took part in the study (response rate, 99.6%) and total of 33,523 students were involved in this study (response rate, 89.4%). In terms of ethnicity, the highest number of students who participated in the study were Malay (63.0%), followed by Chinese (18.1%) and Indian (6.0 %). While the distribution of sex and form among the students were almost the same.
Conclusion
To obtain an accurate representation of the nation's adolescent population for this study, samples from public and private schools that are governed by the Ministries of Education and Rural and Regional Development were deemed to be the most reliable.
