During the COVID-19 pandemic, computer vision syndrome (CVS) related to online classrooms were unavoidable. This cross-sectional study aimed to explore the prevalence, characteristics and associated factors of CVS. A total of 527 students who were currently studying in a virtual classroom (70.40% female, mean (standard deviation; SD) age of 20.04 (2.17) years) were included. The prevalence of CVS assessed by an online CVS-Questionnaire was 81.0% (427/527). Comparing with those in the period before the online study, an increase in screen time (interquartile range) in students with and without CVS was 3 (0–3) and 2 (1–5) h, respectively. Overall, 516 students (97.9%) experienced at least one symptom. The most frequent symptom in CVS subjects was eye pain (96.5%). The most intense symptoms were the feeling of worsening eyesight (15.9%). The factors associated with CVS were female (p < 0.001), age (p = 0.010), atopic diseases (p = 0.020), prior ocular symptoms (p < 0.001), astigmatism (p = 0.033), distance from display <20 cm (p = 0.023), presence of glare or reflection on screen (p < 0.001), low screen brightness (p = 0.045), sleep duration (p = 0.030), inadequate break time between classes (p < 0.001) and increased screen time usage during online study (p < 0.001). Recommendations to prevent CVS based on the adjustable factors might reduce the burden of online study.

This study aims to determine the impact of COVID-19 on the daily lives, agricultural working lives, and mental health of farmers in northern Thailand. This cross-sectional study was carried out in September and October 2021 by interviews. From the stratified random sampling, 2046 farmers responded. There were five sections on the interview form, including demographics, daily life, agricultural working life, stress, and depression experienced during the COVID-19 pandemic. The results show that COVID-19 negatively affected the daily lives of the farmers, making it worse by 61.2%. COVID-19 increased the cost of planting (57.4%) and the cost of agrochemicals and fertilizers (69.9%). It also decreased the prices of agricultural products (73.5%) as well as agricultural extensions (66.5%). The markets and logistics of agricultural products during the pandemic were more difficult than before it (72.8% and 65.1%, respectively). Half of the farmers (50.3%) had moderate stress, and the highest scores were for the loss of household income (mean ± SD = 3.92 ± 0.94) and increased household expenses (mean ± SD = 3.92 ± 0.98). With regard to depression, 19.6% of farmers had depressive symptoms, and the multivariate analysis shows that the mental health of farmers was associated with the changes in their daily and agricultural working lives, as well as with financial problems. The remarkable findings indicate that the farmers who had high and extremely high stress levels had a higher prevalence of depression than the farmers who had no stress (adj.OR = 10.10 and 22.45, respectively). Our results lead to the conclusion that the COVID-19 crisis had an impact on the daily lives, agricultural working lives, and mental health of farmers. The results of this study can be used to provide pertinent guidance, and they have implications for government and other relevant organizations in their COVID-19 efforts to improve agricultural systems and sustain the mental health of farmers.

Agriculture is an important aspect of Thailand's GDP and development. It ranks as the 8th largest exporter in the world, however, pesticide use associated with the agriculture is ranked 18th in the world and 5th in Asia. Previous studies have clearly stated that pesticides are a threat to human health and the environment. The government is now making efforts to address pesticide use and the health impacts of pesticide use, however, these efforts are still in need of completion. This paper aims to summarize: (1) the current situation with regard to pesticide use in Thailand; (2) the current situation with regard to pesticide poisoning in Thailand; and (3) important role of government in reducing pesticide use and risk sustainably in Thailand: current situation and recommendations. This article suggests that government is a significant driver for reducing pesticide use and risk sustainably and the establishment of push and pull policies, legislation, and strategies. The government needs to strictly adhere to international conventions. Introducing a pesticide tax is essential to reduce redundant pesticide use. Updating of the current act, specific regulations with regard to pesticides and strict enforcement are urgently required. Licensing pesticide applicators should be implemented continuously. Promotion of alternative pest management is needed by supportive production inputs, technology, and markets as well as the development of a monitoring and certification system. Educating consumers on how to choose safe agricultural products and reduce risk from pesticide residues in the products is also necessary. All approaches should be implemented simultaneously and instantly. Importantly, the government needs to cooperate with agricultural sectors, health and environmental sectors, private sectors, as well as food industries to tackle complicate issues in a sustainable manner and lower pesticide use and risk sustainably in Thailand.
