WHAT PERSONALITY TRAITS IMPACT YOUR ACTIVITY LEVEL?



A study conducted at the Gerontology Research Centre and the Faculty of Sport and Health Sciences at the University of Jyväskylä observed associations of personality traits with physical activity and sedentary behavior. Individuals characterized by high conscientiousness and extraversion are likelier to accumulate more extended periods of physical activity and sedentary behavior. In contrast, individuals with higher neuroticism scores tend to interrupt their sedentary behavior more often.

The study followed the personality traits of the same individuals when they were 33, 42, 50, and 61 years old. It formed personality profiles representing unique combinations of neuroticism, extraversion, conscientiousness, openness, and agreeableness.

"We identified five personality trait profiles: resilient, brittle, overcontrolled, undercontrolled, and ordinary," says research director Katja Kokko.

In previous research based on the same data, personality profiles have been linked to self-assessed health.

"Individuals who belonged to the resilient profile had the highest level of self-assessed health whereas those with a brittle profile had the lowest level of self-assessed health."

For the first time, the recent study combined data on personality trait profiles with device-based metrics of daily physical activity and sedentary behavior measured at age 61. The personality profiles differed in their usual lengths of time spent in physical activity and sedentary behavior.

Individuals with a resilient profile accumulated both their physical activity and sedentary behavior over extended periods, while those with a brittle profile interrupted their sedentary behavior more frequently.

"The findings may indicate that those with a resilient profile, characterized by high conscientiousness and extraversion, engage more likely in scheduled sports activities," says doctoral researcher Johanna Ahola. "On the other hand, people with a brittle profile, described by high neuroticism, may feel unease about staying sedentary for long periods and prefer light activities.

"Neuroticism has often been associated with higher levels of sedentary behavior. However, in our study, those with a brittle profile interrupted their sedentary behavior often, which is beneficial for health."

The study also examined the relationship between personality profiles and the ratio of physical activity to sedentary behavior, which is meaningful for the risk of mortality among people over 50 in a previous study by other researchers. When the proportion of moderate-to-vigorous physical activity exceeded one-tenth of the time spent sedentary, the 10-year mortality risk decreased more steeply.

"Although there were no statistically significant differences between the personality profiles in either the amounts of physical activity and sedentary behavior or the ratios between the two, the results remain interesting. In light of the existing knowledge, the ratios of individuals with resilient and ordinary profiles were particularly favorable in our study," concludes Johanna Ahola.

The research publication is based on the Jyväskylä Longitudinal Study of Personality and Social Development, where the development of the same individuals has been followed for over 50 years. From 1968 to 2012, the research was led by Professor Lea Pulkkinen, and from 2013 onwards, it has been led by Research Director Katja Kokko. The publication is part of the PATHWAY project funded by the Ministry of Education and Culture and the TRAILS project funded by the Research Council of Finland. The writing of the research article was also supported by the Finnish Cultural Foundation.

PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY

  PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY Building on prior studies with healthy-weight participants, the new research includes different body sizes.         New research indicates that weight influences how and when bodies burn energy. An Oregon Health & Science University study published in the journal  Obesity  found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who are obese spend more energy during the night when most people sleep. The study also found that during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar. "It was surprising to learn how dramatically the timing of when our bodies burn energy differed in those with obesity," said the study's first author, Andrew McHill, Ph.D., an assistant professor at the OHSU School of Nursing and the Oregon Institute of ...

WHAT CAUSES ITCHING, AND WHAT STOPS IT?

  WHAT CAUSES ITCHING, AND WHAT STOPS IT?         It can be a relief to scratch the occasional itch, but when itch gets out of control, it can become a severe health problem. How does the body know when to stop? Scientists at UC San Francisco are getting close to an answer. In a breakthrough that could transform how doctors treat conditions from eczema to allergies, they have discovered a feedback loop centered on a single immune protein called IL-31 that causes the urge to itch and dials back nearby inflammation. The findings, published on October 13th in  Science Immunology , lay the groundwork for a new generation of drugs that interact more intelligently with the body's innate self-regulating ability. Previous approaches suggested that IL-31 signals itch and promotes skin inflammation. However, the UCSF team discovered that nerve cells, or neurons, that respond to IL-31, triggering a scratch, also prevent immune cells from overreacting and causing more ...

A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY

  A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY         In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks. Although it's well-known that eating less meat improves cardiovascular health, diet studies often need to be enhanced by genetic differences, upbringing, and lifestyle choices. By studying identical twins, however, the researchers were able to control for genetics and limit the other factors, as the twins grew up in the same households and reported similar lifestyles. "Not only did this study provide a groundbreaking way to assert that a vegan diet is healthier than the conventional omnivore diet, but the twins were also a riot to work with," said Christopher Gardner, Ph.D., the Rehnborg Farquhar Professor and a professor of medicine. "They dressed the same, they talked the same, and they had a banter ...
