Being ranked among the most sedentary countries, Vietnam’s social public health is challenged by the rising number of overweight people. This study aims to evaluate factors associated with the regularity of exercise and sports (EAS) among Vietnamese people living in the capital city of Hanoi, using data collected from a randomized survey involving 2068 individuals conducted in 2016. Physical exercises and daily sports are considered a major means for improving the Vietnamese social public health system by the government, families, and individuals. Applying the baseline-category logit model, the study analyzed two groups of factors associated with EAS regularity: (i) physiological factors (sex, body mass index (BMI)) and (ii) external factors (education, health communication, medical practice at home). Females with a university education or higher usually exercise less than those with lower education, while the opposite is true for males. The study also shows that those with a higher BMI tend to report higher activity levels. Additionally, improved health communication systems and regular health check-ups at home are also associated with more frequent EAS activities. These results, albeit limited to only one location in Vietnam, provide a basis for making targeted policies that promote a more active lifestyle. This, in turn, could help the country realize the goal of improving the average height of the population and reducing the incidents of non-communicable diseases.

This study focuses on the association of sex differences and psychological factors with periodic general health examination (GHE) behaviors. We conducted a survey in Hanoi and the surrounding areas, collecting 2068 valid observations; the cross-section dataset was then analyzed using the baseline category logit model. The study shows that most people are afraid of discovering diseases through general health examinations (76.64%), and the fear of illness detection appears to be stronger for females than for males (β1(male) = −0.409, p < 0.001). People whose friends/relatives have experienced prolonged treatment tend to show more hesitation in participating in physical check-ups (β2 = 0.221, p < 0.05). On the ideal frequency of GHEs, 90% of the participants agree on once or twice a year. The probability of considering a certain period of time as an appropriate frequency for GHEs changes in accordance with the last doctor visit (low probability of a health examination every 18 months) and one’s fear of potential health problems post-checkup (no fear raises probability of viewing a health examination every 6 months by 9–13 percentage points). The results add to the literature on periodic GHE in particular and on preventive health behaviors in general.

Stress and depression can be seen as the major obstacles for sustained education and attainment of foreign students, and in turn, the sustainability of an education system as a whole. However, the mainstream consideration following Berry’s model on acculturation does not take into account whether students of the host countries are immune to these problems. This study aims to examine the prevalence and predictors of help-seeking behaviors among international and domestic students in a multicultural environment by employing ANOVA and polynomial regression. Some significant results from this study are: (1) Informal sources were the most prevalent sources of help-seeking among international and domestic students, while formal help-seeking was not popular; (2) international students were more likely to overcome emotional difficulties alone and seek help on the Internet than domestic students; (3) acculturative stress was a positive predictor of formal, informal, and miscellaneous help-seeking behaviors among international students and informal help-seeking behaviors or among domestic students; and (4) depression was negatively correlated with the willingness of international students to seek help from informal sources. The findings hint at the risk of acculturative stress faced by domestic students in a multicultural environment being overlooked and the lack of help-seeking sources for international students. The study also provides empirical evidence for policy-planners to design a sustainable education system better at supporting students dealing with depression and acculturative stress.

The topic of sustainability has mostly been tied to economic development and environmental protection, yet not much attention has been paid to the need for high problem-solving capacity as this underlines both issues. One of the most straightforward ways to improve problem-solving capacity is to nurture ‘productive and enduring’, i.e., sustainable, scientific communities. The study examines the co-authoring behaviors of 412 Vietnamese social scientists over the 2008–2017 period via social network analysis to determine if these researchers have formed sustainable scientific communities, using Scopus data. The dataset provides an insightful look into the predominant form of collaboration, i.e., co-authorship, within the Vietnamese social science research communities. Through basic network metrics such as density and clustering coefficient, the study hypothesizes that the socially sustainable research communities are those with low clustering and high density. As any scholar's position in a network can be specified by three quantities: the number of publications, connections, and years in research, the distance metrics from the most productive to the rest are computed and compared. The study hypothesizes that if the distance is too large; it reflects the socially unsustainable situation in the network. The results indicate that certain level of social unsustainability exists in social sciences groups in Vietnam. Though the results are only indicative, it has opened up a fertile space for future inquiry into this matter.

A study on over 2000 patients has been conducted in Hanoi, Vietnam, to explore the influences of psychological and socio-economic factors on the evaluation of healthcare quality and public health by patients. The findings suggest effective health communication and the status of being married are two elements that have the strongest impact on people’s positive perceptions about healthcare quality (βHealthCom = 0.210, βotherMaritalstt = −0.386, p < 0.001). Young unmarried people and the insured tend to be more critical of healthcare quality (βAge = −0.005, p < 0.05; βyesHealthIns = −0.208, p < 0.001). At the same time, a higher BMI and better view of health care quality are linked to negative opinions about community health. These outcomes suggest that in order to maintain collective health as part of social sustainability, the Vietnamese government should pay attention to infrastructure improvement, insurance system reforms, and communication of personal health care knowledge.
