The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

49.9K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Social Traps01:41

Social Traps

22.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Cross-Sectional Research

11.3K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

144
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Naturalistic Observations

15.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Data Collection by Observations01:08

Data Collection by Observations

12.0K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Summary

Canadian youth and adults spend 4-5 hours daily sedentary at school or work. This sedentary time (ST) is linked to poorer mental and general health outcomes, highlighting the need for targeted interventions.

Area of Science:

  • Public Health
  • Epidemiology
  • Behavioral Science

Background:

  • High sedentary time (ST) is linked to adverse physical and mental health outcomes.
  • Schools and workplaces are significant environments where Canadians spend substantial daily time, making them key targets for ST reduction strategies.

Purpose of the Study:

  • To estimate daily school and work ST among Canadian youth and adults.
  • To examine variations in ST across sociodemographic subgroups.
  • To determine the associations between school and work ST and health indicators.

Main Methods:

  • Utilized the 2020 Canadian Community Health Survey Healthy Living Rapid Response module (N=5242).
  • Estimated sitting time during school and work for youth (12-17 years) and adults (18-34, 35-64 years).
  • Employed independent t-tests for subgroup comparisons and adjusted logistic regression for health associations.

Main Results:

  • Canadian youth (12-17 years) and adults (18-34 years) averaged 4.5 and 5.2 hours/day of school ST, respectively.
  • Adults (18-34 and 35-64 years) reported 3.9 and 4.0 hours/day of work ST, respectively.
  • Higher school ST in adults (18-34 years) correlated with lower odds of excellent/very good mental health; higher work ST correlated with better general health.

Conclusions:

  • Canadian youth and working-age adults accumulate 4-5 hours daily of sedentary time at school or work.
  • This study provides the first estimates of school and work ST in a representative Canadian sample.
  • Findings underscore the importance of environment-specific behaviors for targeted interventions and addressing health inequalities related to ST.
