207 questionnaires were returned by first year students in 2016, 175 by second years in 2017 and 103 by third years in 2018. Students were predominately female, with proportions of 86%, 73% and 84% each year respectively. Mean (median) ages were 24 (22) years, 25 (23) years and 27 (25) each year. From the numbers of student identified within each year group, the response rates were 88%, 81% and 52% respectively. Table 1 presents summary results.

Table 1: Summary results for health and health behaviour measures for a cohort of undergraduate nursing students in the first, second and third years of their degree programme
In relation to physical health, slightly higher proportions of third year students rated their health as excellent or very good compared to proportions within the two previous year groups, but a lower proportion rated their health as good. This was reflected by slightly higher proportions rating their health as fair/poor. This contrasted strongly with results for mental health. There was a clear decline over the three years in the proportions of students rating their mental health as excellent/very good/good and a concomitant clear increase in those rating their mental health as fair/poor. This result was backed up by the results of the WEMWBS score. Not only did the mean score decline over the three years, but the proportion of students with a WEMWBS score of <46 (indicating either high risk of major depression, or in high risk of psychological distress and increased risk of depression) increased from one quarter to one half.
Health behaviours were also investigated. Physical activity levels declined over the study period, with the proportion of students managing 150 minutes of physical activity per week decreasing from three quarters in the first year to two thirds in the third year. This was reflected in higher self-reported sedentary time. The results for dietary behaviour were less clear cut. Slightly higher proportions of students over time rated their diets as healthy or unhealthy, with fewer rating them as average. There was a decrease in the proportion of students eating breakfast most days (but no difference for consumption of fruit and vegetables, and takeaways. However, there were no clear differences over time in mean BMI, or proportions of students with a BMI categorising them as overweight or obese.
Although there was a small increase over time in the proportions of students who reported sleeping poorly or very poorly, and there were slightly higher, proportions of students who reported sleeping for less than seven hours per night and looking at their devices more than 30 minutes before going to sleep. There were no overall differences in alcohol consumption over time, apart from an increasing number of students drinking only occasionally or never. Binge drinking appeared to peak in second year students. The proportion of students smoking (current or occasional) decreased from 24.7% to 19.4% over the course. The decline was most marked for current smokers; whereas occasional smoking was higher among second year students, perhaps indicating that some smokers were cutting down and moving from daily to occasional smoking.
We identified 51 students for whom data was available for all three time-points. The results of the regression analyses, using a Bayesian approach, are presented in Table 2. They suggest a clear effect of worsening WEMWBS score over time, but no effect on smoking or physical activity behaviour. The other notable result was that males had poorer WEMWBS scores. However, among this sub-sample of 51 students, the proportion of smokers (15%) was lower, and the proportion achieving 150 minutes of physical activity (84%) was higher than in the overall sample during the first year. In contrast, their mean WEMWBS score as baseline was very similar to that of the overall cohort.
