Grade 5's Around The World

I will send out a survey to multiple places around the globe to collect data. I mainly am interested in the sleep habits, screen time habits and physical activity of grade 5 students around the world.

Problem

Physical activity, sleep and regulated screen time are important health factors in children.

 

This project intends to investigate how different or the same grade fives are in terms of sleep, activity and screen time. Through a questionnaire I asked about how long they are on screen, what tech they own, when they wake up and go to bed as well as a few related topics. Then I compared the data of kids in different regions with each other and the guidelines I found on google scholar. I believe these topics all affect overall health. I am curious what similarities and differences exist for kids this age around the world.

 

 

Method

First I made a questionnaire in Google forms. Then my mum helped me make a workflow on Dubsado So we could get an informed consent signed by a guardian before providing a link to the survey. Once a guardian signed the consent it would email them a link to the survey for their Grade 5 child to fill out. 

We left the survey up for one month. After taking in the results we had 90 responses. My dad and I then analysed the results. To confirm my first two hypotheses I calculated the results in Google Sheets. For the third I could calculate it in sheets but my dad helped me check if the result was significant using an independent samples t-test in SPSS. For the other three hypotheses, my dad helped me and we conducted a Pearson-r correlation in SPSS to determine if there was any significant correlation present.

Then I generated charts in a Google Sheet with all of my data in it. Then I decided what charts would be the best and formatted the chart correctly and represented all the data on my trifold.  

 

 

 

Research

“Guidelines recommend ≥60 minutes per day of physical activity, ≤2 hours per day of screen time, and 9–12 hours per day of sleep for individuals aged 6–12 years” (Friel et al., 2020) 

Sleep guidelines

The minimum recommended sleep duration for school aged children is 9 hours per night. (Hirshkowitz et al., 2015 and Friel et al, 2020)

Physical activity guidelines

“60 min of moderate-to-vigorous intensity physical activity daily, although more physical activity beyond 60 min of MVPA daily appears to be better for various health outcomes” (Chaput et al., 2020)

Screen use guidelines

It is recommended that daily screen time does not exceed 2 hours per day (Friel et al, 2020)

Data

Hypothesis #1 - more kids in North America will have a phone than kids from outside North America

To test this hypothesis, we sorted the data in Google Sheets and calculated the percentage of kids in North America that have their own phone (38%) and the percentage of kids outside North America that have their own phone (82%)

This hypothesis was not supported by the data.  

 

Hypothesis #2 - of the kids with phones, more will be allowed to have them in their room at night than those not allowed 

To test this hypothesis we sorted the data in google sheets and calculated the percentage of kids with phones who were allowed to have it in their room at night (67%) and who weren't (33%).

This hypothesis was supported by the data.  

 

Hypothesis #3 - kids who are allowed to have their phone in their room at night will average less sleep at night

To test this hypothesis we sorted the data in google sheets and we calculated the mean hours of sleep for people with phones in their room (8.97 hours) and compared that to the mean hours of sleep for the people without their phones in their room at night (9.59 hours). Then my dad helped me determine if the difference between the means was significant by showing me an independent samples t-test. There was a significant difference between the means (p<.05)

This hypothesis was supported by the data.  

 

Hypothesis #4 - the more screen time a kid has, the less time they will spend in sports 

To test this hypothesis we had to examine the relationship between two variables. I did not know how to do that in Google sheets so my dad showed me how to run a Pearson-r correlation in SPSS, a stats program for social sciences. I learned that a correlation tells you the strength and direction of a  relationship. The data show there is not a significant correlation (p>.05)

This hypothesis was not supported by the data.

 

Hypothesis #5 - kids with more screen time will report feeling tired in the morning more frequently 

To test this hypothesis we had to examine the relationship between two variables. As in the last hypothesis we used a Pearson-r correlation to investigate the relationship between screen time and sleep quality. The data show that there is no significant correlation between the variables (p>.05)

This hypothesis was not supported by the data

 

Hypothesis #6 - kids with more time physically active will report feeling tired in the morning less frequently 

To test this hypothesis we had to examine the relationship between two variables. We used a Pearson-r correlation to investigate the relationship between Physical activity and sleep quality. The data show that there is a weak but significant relationship between the two variables in the predicted direction (p<.05).

This hypothesis was supported by the data

Conclusion

I really enjoyed doing this project and I learned that in some ways kids are different but all kids are relatively the same. I learned that around the world there are different social media platforms that I had never heard of. On the topic of social media I learned that once a kid gets a phone they are much more likely get on social media. I also found that the countries with the most kids with phones had the least average amount of sleep.

I learned that it is very important for kids to get physical activity in school. The average amount of time spent in sports outside of school was similar around the world but outside of Canada the kids were not getting as much physical activity in school. Therefore, more kids were not meeting the guidelines for total physical activity. I found that kids who got more physical activity reported feeling less tired in the morning. 

One major limitation of the study was that it did not have a large enough group of people, therefore  we did not have an accurate representation of each participating country. I would like to see this done with a larger study
