Methods
- Paste quoted text from the Methods section of the article on the next line. Do not include quotation marks or a bullet mark:
Healthy children were recruited by advertisement between October 2018 and March 2020 and were eligible to participate if they were aged 8 to 12 years; lived in the wider Dunedin area in New Zealand; had no underlying medical conditions or medications that could affect sleep; and scored 39 or lower, which indicated no major sleep problems, on the Sleep Disturbance Scale for Children.
- Write your translation on the next line:
The researchers gathered healthy children from the Dunedin district of New Zealand who were between the ages of 8 and 12. The kids were allowed to take part provided they didn’t take any medications that could interfere with their sleep or have any medical concerns.
Introduction
- Paste quoted text from the Introduction of the article on the next line. Do not include quotation marks:
To our knowledge, no experimental studies have yet determined the effect of manipulating sleep on HRQOL in healthy children to the extent that might represent the levels of mild sleep deprivation that many children may experience today.22 The aim of this secondary analysis was to determine the effect of mild sleep deprivation (induced via the Daily Rest, Eating, and Activity Monitoring [DREAM], a home-based sleep manipulation trial) on HRQOL in children without major sleep issues.
- Write your translation on the next line:
Researchers intended to determine whether healthy children’s quality of life is affected by slight sleep losses. Since this had not been experimentally tested in earlier research, this study looked at the effects of mild sleep deprivation on children’s mental health and health generally.
Results
- Paste quoted text from the Results section in the article on the next line. Do not include quotation marks:
Children reported significantly lower scores for physical well-being (SMD, -0.28; 95%CI, -0.49 to -0.08) and ability to cope well in the school environment (SMD, -0.26; 95% CI, -0.42 to -0.09), leading to total HRQOL scores that were significantly lower when tired (SMD, -0.21; 95%CI, -0.34 to -0.08).
- Write your translation on the next line:
Children’s overall quality of life declined as they slept less. They felt worse physically and had more difficulty coping at school compared with when they slept more.
Discussion
- Paste quoted text from the Discussion section of the article on the next line. Do not include quotation marks:
Results of this secondary analysis of the DREAM trial demonstrated that even relatively small reductions in nightly sleep duration can have a considerable effect on HRQOL in children.
- Write your translation on the next line:
Even a small amount of lost sleep can negatively affect children’s health and overall well-being.
Future Directions
- What future research should follow up on this work?
In my opinion, future research should examine the long-term effects of reduced sleep on children’s quality of life and confirm these findings in more diverse populations, if no research has been done already on this.
Difficult Material
- What did you not understand about this paper that someone else may be able to help you with? Or, if you understood everything, what did you find most challenging to understand?
Personally, one challenging part of the paper was understanding the statistical terms such as standardized mean difference (SMD) and confidence intervals, which require some background knowledge in statistics to interpret properly.

Discussion
Paste quoted text on the next line. Do not include quotation marks or a bullet mark:
We found that when children slept less, they ate substantially more calories, particularly in the evenings, all of which came from noncore foods (generally those with poor nutritional quality) rather than from core foods, such as fruit and vegetables, which are associated with higher HRQOL.
Write your translation on the next line:
We found that when children slept less, they consumed more calories from nutritionally poor foods, which are associated with lower health-related quality of life.
Additional Future Directions:
What future research do you think should follow up on this work?
Another direction for future research not mentioned is to expand this study to include children of various ages. The age range of this study was 8 -12 (with a mean of 10.3). It would be interesting to see whether a similar study conducted with younger and/or older children would produce similar results, and/or to identify any differences between age groups.
Difficult Material (from original poster or subsequent student):
What did the previous poster state was difficult to understand? (Please copy and paste their statement here):
Personally, one challenging part of the paper was understanding the statistical terms such as standardized mean difference (SMD) and confidence intervals, which require some background knowledge in statistics to interpret properly.
Please try to explain the difficult materials to the original poster, as best as you can. (This is where you can help them understand what they found difficult.)
According to the “statistical analysis” section of the study, it mentions “Mean
differences and 95% CIs were determined for sleep restriction compared with sleep extension. Standardized mean differences (SMDs) and 95%CIs were also calculated using a pooled SD”. This information is helpful for understanding the standardized mean difference (SMD), which compares the means of two conditions, expressed in standard deviation units. It is also helpful to know that SMD standardizes the difference independent of the original measurement scale. In this study, the two conditions are sleep restriction and sleep extension.
Therefore, when the paper later reports SMD values such as −0.28, this indicates that scores during the sleep restriction condition were 0.28 standard deviations lower than during the sleep extension condition. The negative value shows that the outcome was lower in the sleep restriction condition.
The 95% confidence interval (CI) used in this study provides a range of values that, based on the data, likely contains the true effect of the intervention. In this study, the “intervention” refers to the sleep restriction condition, and the effect is measured as the difference in scores between the sleep restriction and sleep extension conditions. The CI helps illustrate the uncertainty around the estimated effect. Generally, if the CI lies entirely below 0, this indicates a statistically significant reduction. If the CI crosses 0 (e.g., −0.10 to 0.15), the effect is not statistically significant. A wider CI indicates greater uncertainty or a less precise estimate, while a narrower CI indicates greater precision. Many of the 95% CIs reported in the study were entirely below 0, suggesting that the observed effects are likely true decreases.
New Difficult Material (according to you):
What did you not understand about this paper, that someone else can help with? If you understood everything, then what did you find most challenging to understand?
Like the original poster, I found the statistical information in this paper to be the most challenging part. One data point that particularly caught my attention was the “per-protocol sample” in Table 2. I was initially confused because the number of participants was under 60, whereas I had expected it to be around 100. After rereading the methods, I realized that the per-protocol sample included only children who had a difference in sleep of at least 30 minutes per night. With this clarification, the numbers in the table made much more sense.
