Relationships of Acculturative Stress, Perceived Stress, and Social Support with Oral Health-related Quality of Life among International Students in Malaysia: A Structural Equation Modelling

Oral health knowledge, attitudes, behaviours and status among international post-secondary students: a scoping review

Objective

This scoping review aims to review and synthesize existing literature on oral health knowledge, attitudes, behaviours, barriers, and status among international post-secondary students.

Methods

Using the Arksey and O'Malley framework, MEDLINE, Embase, Dentistry & Oral Sciences Source, CINAHL, Web of Science, and Scopus databases were searched in June 2024 for selected oral health and international student keywords. Manual searches of reference lists and citations were also conducted. Original research studies in English language were included, with no geographical or date limitations. Using Rayyan, duplicates were removed, and then two authors independently screened available literature according to eligibility criteria; inconsistencies or disagreements were resolved through a third author.

Results

The search yielded 984 articles. After removal of duplicates and those inconsistent with our inclusion criteria, 14 articles remained. In total, 13/14 articles used a cross-sectional design implementing surveys or interviews; only 4 articles presented objective clinical measures (e.g., DMFT, objective periodontal measures). Some included articles provided information about dietary habits relevant to oral health; however, information captured was limited. Overall, compared to the domestic students, international students were reported to have poorer oral health status; more gaps in their knowledge, attitudes and behaviours regarding oral health; and were also less likely to obtain routine oral health care.

Conclusion

International students may face significant challenges in managing and optimizing their oral health vs. domestic students due to various factors (e.g., acculturation stress, finances, diet, academic stress etc.). Post-secondary institutions may want to consider focusing on supporting and empowering international students to access oral health care on a regular basis through targeted interventions. To design impactful interventions, future community engaged research is needed to better understand the perspectives of international students regarding their oral health status, knowledge, attitudes, behaviours, needs, and aspirations.

Oral health-related quality of life and its association with sense of coherence and social support among Yemeni immigrants in Malaysia

Oral health problems prove to be a significant public health issue due to their high prevalence and their impacts on people's self-confidence and basic physical functions such as talking, chewing and smiling, all of which affect an individual's social role. For that, this study aims to determine oral health-related quality of life (OHRQoL) and its association with a sense of coherence (SOC) and perceived social support among Yemeni adults residing in Malaysia. Data was collected from 223 Yemeni adults residing in Malaysia for over a year. The data collection instruments used were: a short version of the sense of coherence Scale (SOC-13), a new short version of the oral health impact profile (OHIP-5) questionnaire, the multidimensional scale of perceived social support (MSPSS), and a questionnaire containing socio-demographic and oral health behaviours information. Simple and adjusted binary logistic regression analyses with the level of significance p < 0.05 were used to determine the association between the independent factors and OHRQoL. Negative impacts on quality of life due to oral health issues were reported by (57.8%) of the participants, and a statistically significant association between SOC and OHRQoL was found; participants with weak SOC were more likely to have a negative impact on their OHRQol than individuals with strong SOC (AOR = 2.8, 95% CI 1.4-5.5). Additionally, self-assessment of oral health as poor (AOR = 4.6, 95% CI 1.5-14.1) were also associated with a negative impact OHRQoL. On the other hand, this study found that a longer period since the last dentist visit was a protective factor against negative impacts on quality of life (p < 0.05). In terms of perceived social support, no association was found between any categories of perceived social support and OHRQoL. In Conclusion, sense of coherence showed a statistically significant association with OHRQoL, emphasizing psychological factors' potential role in oral health. The findings support the hypothesis that SOC is a psychosocial determinant that could act as a protective factor against negative impact on OHRQoL.

The relationship between acculturative stress and psychological outcomes in international students: a systematic review and meta-analysis

Introduction

The current systematic review aimed to examine the relationship between acculturative stress (AS) and psychological outcomes in international students to determine the role AS may play in predicting the mental health of international students.

Methods

The studies included in the current systematic review and meta-analysis had considered AS and its impact on psychological outcomes among international students studying abroad. After checking the studies found in our primary search through the scientific databases in terms of our eligibility criteria, 29 studies were included, of which 26 were eligible for a meta-analysis (total N = 7,247).

Results

Meta-analysis indicated a moderate mean correlation of AS with psychological outcomes like depression, life satisfaction, quality of life, vocational outcome expectations, drinking behaviors, resilience, health promotion behavior, psychological adjustment, psychological distress, negative affect, and mental health symptoms (r =  0.39) and depression (r =  0.41), respectively.

Discussion

The review of studies revealed a robust relationship between AS and increased negative psychological outcomes such as depression, psychological distress, and general stress, as well as decreased positive psychological outcomes such as psychological adjustment, mental health, life satisfaction, and quality of life.

Role of behavioural and age-related factors in the long-term impact of tooth loss on oral health-related quality of life: A 25-year follow-up of Swedish older adults

OBJECTIVES

The primary aim of this study was to assess any long-term association between tooth loss at age 50 and subsequent impaired oral health-related quality of life, OHRQoL, at age 65, 70 and 75, adjusted for time invariant socio-demographic-and time variant behavioural and age-related factors in terms of disadvantages with functional, social, health and psychological concerns. As a second aim, this study examined whether behavioural- and age-related factors played a role in explaining any long-term association between early tooth loss and subsequent OHRQoL.

METHODS

In 1992, 6346 residents, aged 50, consented to participate in a prospective cohort study and 3060 completed postal questionnaire follow-ups every fifth year (six in total) until 2017. Information on tooth loss was assessed at baseline at age 50. Behavioural- and age-related covariates were assessed repeatedly at ages 65, 70 and 75. OHRQoL was the repeated outcome measure assessed by the Oral Impact on Daily Performance, OIDP at age 65, 70 and 75. Generalized Estimating Equations, GEE, with binomial logit function was used to test the association between tooth loss and prevalence of oral impacts (OIDP) adjusting for counfounders and potential mediators. The role of behavioural and age-related factors in explaining the association between early tooth loss and OHRQoL was tested using the change in estimate approach.

RESULTS

Tooth loss and time variant behavioural- and age-related covariates associated independently with higher odds of impaired OHRQoL across time. The long-term impact of tooth loss seemed to be partly explained by time variant covariates related to functional and psychological concerns. Participants who had excessive tooth loss at age 50 were 2.5 times more likely to experience oral impacts before adjustment of covariates. After adjustment of functional- and psychological-covariates, participants were, respectively, 1.6 times and 1.4 times more likely to experience oral impacts.

CONCLUSION

This study revealed that early tooth loss at age 50 was independently associated with subsequent impaired OHRQoL at ages 65, 70 and 75. The aspects of behavioural- and age-related factors in terms of disadvantages in functional and psychological concerns seemed to play a role in explaining the long-term impact of tooth loss on impaired OHRQoL. A mid-life approach to the prevention of tooth loss for the protection of subsequent adverse health outcomes should guide health promotion interventions and also be recognized by oral health care providers both for patient interaction and clinical decision making.

Social support, oral health knowledge, attitudes, practice, self-efficacy and oral health-related quality of life in Chinese college students

Oral health is crucial for health-related quality of life. However, the research on the factors affecting oral health status is not comprehensive enough. This investigation aimed to evaluate the multifaceted determinants of college students' oral health status and explore the impact of social support, oral health literacy, attitudes, behaviors, and self-efficacy on OHRQoL. By surveying 822 students from a university. Baseline data included sociodemographics (gender, age), social support (MSPSS scale), oral health self-efficacy (SESS scale), oral health knowledge, attitudes, and practices (KAP questionnaire), and OHRQoL (OHIP-14 scale). Based on social cognitive theory, partial least squares structural equation modeling (PLS-SEM) and fuzzy set qualitative comparative analysis (fsQCA) were used to examine the relationship between the study variables. PLS-SEM results showed that knowledge, attitude, and practice predicted OHRQoL through self-efficacy. FsQCA results showed that the combination of different variables was sufficient to explain OHRQoL. The conclusion was that self-efficacy plays an important role and the combination of high-level knowledge, positive attitudes, and strong self-efficacy was important in improving OHRQoL. The results of this study provided a reference for the oral health strategy planning of college students in China.

Perceptions of the Sense of Security, Belonging, and Acculturative Stress among International Students in China during COVID-19 Outbreak-An Empirical Analysis

Understanding the cross-cultural adaptation of students studying in foreign countries by exploring acculturative stress factors is crucial to ensure the smooth academic performance of the students and, in turn, to enhance the global reputation of their universities. Therefore, it is an area of interest for the authorities (Ministry) and the corresponding management of universities. Using a random sample of 138 international students in China, descriptive and logistic regressions were conducted to assess the levels and influence of acculturative stress factors on cross-cultural adaptation, specifically on international students' sense of security and belonging during the COVID-19 pandemic outbreak. The results revealed that students were most concerned about homesickness, which obtained the highest mean score. The regression results indicated that the perception of fear and discrimination significantly impacted international students' sense of security. The perception of fear, guilt, and how long the student stayed in China also significantly affected the sense of belonging. We argue that the reflections provided herein are essential for universities to improve how they manage and handle international students to mitigate the effects of acculturative stress, particularly when additional stressful conditions are present, such as the COVID-19 pandemic.
