Determinants of oral health-related quality of life among undergraduate university students: A cross-sectional study.

INTRODUCTION

Young adulthood is a critical period for establishing lifelong health behaviours, yet oral health is often neglected. This study investigated factors associated with oral health-related quality of life (OHRQoL) among Malaysian university students.

MATERIALS AND

METHODS

A cross-sectional survey was conducted among 395 undergraduate students aged 18 to 25 years. Data were collected using a structured questionnaire assessing sociodemographic characteristics, perceived oral health status, oral healthcare seeking behaviour, and OHRQoL via the short Malay version of the Oral Health Impact Profile (S-OHIP(M)). Multiple linear regression was used to identify predictors of OHRQoL.

RESULTS

The prevalence of OHRQoL impact was 41.0%, with a mean S-OHIP(M) score of 9.15 (SD=6.39). Significant predictors of poorer OHRQoL included having at least one oral health problem, dissatisfaction with oral health status, and visiting the dentist due to an oral health issue. Dental and medical students reported significantly better OHRQoL compared to health sciences students. Oral health care seeking behaviour, although generally favourable, was not significantly associated with OHRQoL.

CONCLUSION

OHRQoL among young adults is influenced by both subjective perceptions and behavioural patterns. Promoting routine dental visits and enhancing oral health awareness may improve quality of life outcomes. These findings inform strategies for preventive care and service delivery targeting young adult populations.
