This study determines the differences in health risk behavior, knowledge, and health benefit beliefs between health science and non-health science university students in 17 low and middle income countries. Anonymous questionnaire data were collected in a cross-sectional survey of 13,042 undergraduate university students (4,981 health science and 8,061 non-health science students) from 17 universities in 17 countries across Asia, Africa, and the Americas. Results indicate that overall, health science students had the same mean number of health risk behaviors as non-health science university students. Regarding addictive risk behavior, fewer health science students used tobacco, were binge drinkers, or gambled once a week or more. Health science students also had a greater awareness of health behavior risks (5.5) than non-health science students (4.6). Linear regression analysis found a strong association with poor or weak health benefit beliefs and the health risk behavior index. There was no association between risk awareness and health risk behavior among health science students and an inverse association among non-health science students.

Background Hong Kong is a densely populated city with a low incidence and mortality of coronavirus disease 2019 (COVID-19). The city imposed different levels of social distancing including, the closure of sports venues and restrictions on eateries. This inevitably affects the eating behaviour and physical activities of the population. We examined the changes in eating behavior and physical activities before and during the COVID-19 pandemic, and identified sociodemographic factors associated with the behavioral changes. Methods This was a cross-sectional study via a random telephone survey of Chinese adults conducted in Hong Kong from May to June, 2020 - a period in which social distancing measures were being imposed. We measured the physical activity habits from four aspects and dietary consumption patterns from seven aspects before and during the pandemic based on the World Health Organization’s guidelines and previous publications. Results In total, 724 participants were recruited. Individuals were found to cook more frequently at home (p < 0.001) and order take-out (p < 0.001) during the COVID-19 pandemic. While no significant change in the frequency of fast food consumption was observed, we found significant increases in the frequency of eating fruits (p < 0.001) and vegetables (p = 0.004). The frequencies of walking, moderate-intensive sports, and high-intensity sports were significantly reduced (p < 0.001). We found that healthy lifestyle behaviors during the pandemic were negatively associated with participants’ economic status. Conclusions Social distancing measures likely provided an opportunity for individuals to stay home and thus eat healthier. However, in a prolonged period of social restrictions, a lower physical activity level poses a risk to public health. Public health officials are thus advised to monitor physical health on a population-wide basis. The findings highlighted the importance of interventions tailored to individuals who have prolonged home stays - particularly for individuals in the low economic group.

This study investigated whether the consumption of fruit and vegetable by Chinese primary students in Hong Kong is associated with their mother's (1) nutrition knowledge on fruit and vegetables; (2) attitude towards healthy eating; and (3) fruit and vegetable consumption. Fourth- and fifth-grade students from 10 primary schools located in different districts, along with their mothers, were invited to each fill-in a questionnaire related to their diet intake. Accomplished questionnaires were matched and analysed. There were 1779 mother-child pairs who were successfully matched. Chi-square analysis revealed that students' fruit consumption is associated with their mother's (1) knowledge on fruit and vegetables (P = 0.006); (2) attitude towards healthy eating (P = 0.010); and (3) fruit consumption (P < 0.001). Students' vegetable consumption exhibited the same association with their mother's (1) knowledge (P < 0.001), (2) attitude towards healthy eating (P = 0.005), and (3) vegetable consumption (P < 0.001). Logistic regression showed that knowledge, attitude and dietary practice of mothers were independent factors associated with the consumption of fruit and vegetables by students and are not influenced by the level of education and household income. The results highlight the important role of parents in promoting fruit and vegetable consumption to primary students. It reaffirmed the importance of parent nutrition education in the formulation of a comprehensive health promotion strategy to school-aged children.

Students' responses towards university pandemic measures were largely positive, but sensitivity towards these measures varied between groups by country of study. This should be considered in further comparative studies.
