ObjectiveThis study aims to determine the prevalence of high screen time among schoolchildren aged 3–10 years in Bhaktapur, its correlates and the parents’ strategies to reduce screen time during the COVID-19 pandemic in Nepal.Methods and analysisThis cross-sectional descriptive study was conducted during March 2021. A total of 630 households were selected for the study from 21 randomly selected clusters in Bhaktapur, Nepal. Correlates of high screen time were determined using a logistic model. P<0.002 was taken as significant.ResultsAmong all the participants, the mean (SD) age was 7.0 (2.2) years, with 50.3% male participation. Few participants had online classes (n=24, 3.8%). The prevalence of high screen time among the participants was very high (55.2%, 95% CI=51.3% to 59.1%), which is even higher in boys (61.8%, 95% CI=58.0% to 65.6%). The median screen time before the COVID-19 pandemic was 1.0 hours (mean rank=275.8) which increased to 2.2 hours (mean rank=116.6) during the pandemic (p<0.001). Participants having smartphones were about seven times (adjusted OR=6.9, 95% CI=1.5 to 31.3, p=0.013) more likely to have high screen time than those who did not have the device. Most parents used to reprimand and urge their children to play outside to limit their screen usage.ConclusionDuring the COVID-19 pandemic, about one in two schoolchildren of 3–10 years had higher screen time than before the COVID-19 pandemic. Parents’ strategies to reduce screen time were not effective. An intervention study is recommended to design and test effective strategies to reduce screen time and its negative effects on children’s health.

Any bodily movement produced by skeletal muscle which requires energy expenditure is known as physical activity (PA). WHO has recommended that at least 150 minutes of moderate or 75 minutes of vigorous-intensity PA or a combination of both per week is required for health benefits. Physical inactivity is one of the strongest risk factors for noncommunicable diseases (NCDs) and other conditions and is attributable to 6% of global premature death. However, data on the PA of teachers are unavailable in Nepal. They are considered one of the risk groups for NCDs because of the less active nature of their job. So, we aimed to evaluate the effect of the educational intervention based on the theory of planned behaviour on PA intention among secondary school teachers in Bhaktapur district, Nepal. For this study, we recruited 126 teachers from 6 schools. Each intervention and control group contained three randomly selected secondary schools. All the teachers from the selected schools were enrolled in the respective groups. A quasiexperimental (pretest-posttest control group) study design was used to test the effectiveness of the intervention on attitude, behaviour control, subjective norms, and intention for engaging in regular PA. Both groups underwent baseline and follow-up assessments at four weeks using the self-administered questionnaire developed for this study. The intervention group delivered a one-hour lecture session supported by audio-video materials for PA promotion. The effect was analysed by comparing the changes in the theory of planned behaviour (TPB) constructs within and between intervention and control groups. The difference in scores between and within the groups was tested using Student’s t -test. Adjusted difference-in-difference scores were calculated through linear regression. Data analysis was done using Statistical Package for Social Science version 26.0. The adjusted mean score increase in TPB constructs due to the interaction of time and intervention increased from 0.641 to 1.381. The highest gain ( beta = 1.381 ) was seen in the intention score, while a minor improvement was seen in perceived behavioural control ( beta = 0.641 ). After the intervention, the net increase in PA intention score was 9.35% compared to the control group. Thus, the promotion package was effective in increasing PA intention. The findings of this study and educational package could be helpful in encouraging teachers to engage in PA in other schools.
