Research Summary: University of Colorado Boulder Study on Sitting and Health
Introduction
Researchers at the University of Colorado Boulder conducted a comprehensive study to investigate the impact of prolonged sitting on cardiovascular and metabolic health in young adults. The study utilized data from the Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging (CATSLife) and analyzed the relationship between sitting time, physical activity, and health indicators such as body mass index (BMI) and total cholesterol/high-density lipoprotein ratio (TC/HDL).
Methods
The study analyzed data from over 1,000 former or current Colorado residents, including 730 twins. The researchers used a co-twin control analysis to examine the effects of sitting and physical activity on health outcomes. The study also utilized self-reported data, which is a limitation of the study.
Findings
The study found that prolonged sitting was associated with higher TC/HDL and BMI levels. Specifically, young adults who sat for 60-plus hours per week were at a higher risk of developing heart disease and may experience accelerated signs of aging. The researchers also found that vigorous physical activity was a more effective counter to the negative effects of prolonged sitting than moderate physical activity.
Key Results
Implications
The study's findings have significant implications for public health initiatives and guidelines. The researchers suggested that guidelines should be adjusted to account for sitting time throughout the day, and that clear messaging should be provided to the public about the importance of reducing sitting time and increasing vigorous physical activity.
Recommendations
The researchers recommend that young adults try to reduce their sitting time by using standing desks, taking breaks, and organizing walking meetings, and also engage in vigorous exercise for at least 30 minutes per day.
Limitations
The study's limitations included the use of self-reported data and the limited diversity of the sample. However, the study's findings provide valuable insights into the effects of sitting and physical activity on cardiovascular and metabolic health in young adults.

The Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging (CATSLife)
Introduction
The Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging (CATSLife) is a prospective study that aims to investigate how early and current influences contribute to cognitive functioning over a person's lifetime. The study seeks to understand the developmental, genetic, and environmental factors that interact to shape cognitive performance, physical, and behavioral health during midlife.
Study Design and Objectives
CATSLife is a genetically sensitive study that combines the strengths of both twin and adoption methodologies to evaluate individual differences in rates of growth and maintenance of abilities and to evaluate specific genetic, biomarker, behavioral health, and environmental pathways that can change cognitive functioning. The study has five aims nested within two overarching goals: to evaluate individual differences in rates of growth and maintenance of abilities and to evaluate specific genetic, biomarker, behavioral health, and environmental pathways that can change cognitive functioning.
Study Participants
The study targets up to 1600 participants between the ages of 30 and 40 years who have been studied almost yearly from birth to early adulthood. The participants include 776 adoptive and non-adoptive probands and siblings, as well as 824 twins, who were previously assessed on a wide array of measures almost yearly from birth into their 20's.
Measures and Assessments
The study measures a wide array of indices of normal behavioral development, including cognitive function, physical health, and function, as well as potential moderators and mediators. The primary measures of cognitive function include education, work, religion, neighborhood, life events, financial distress, and specific cognitive battery tests. The study also assesses behavioral health, including self-rated health, illness ratings, diet and nutrition, sleep quality, and momentary survey measures. Physical assessment and biomarkers include weight, girth, grip strength, spirometry, lipid panel, brain-derived neurotrophic factor (bdnf), DNA, APOE, and Affymetrix Axiom Precision Medicine Research Array.
Data Collection and Analysis
Data from 1,245 respondents who provided consent to share their data are included in this study. Specifically, the data release includes information on APOE isoforms and IQ data, with up to three assessments across childhood and adolescence. The study's findings have the potential to inform strategies for promoting healthy cognitive aging and preventing age-related cognitive decline.
Findings and Implications
The study has already published several papers on the topic, including research on the impact of childhood socioeconomic status on late midlife cognitive abilities and the role of geospatial features in cognitive maintenance. Some of the key findings from CATSLife include the importance of early childhood genetic and environmental factors in shaping adult cognitive maintenance and change, as well as the role of proximal influences and innovations that emerge across development. The study has also highlighted the importance of geospatial features, such as the density of parks within a 1-mile radius, in cognitive maintenance.
Future Directions and Funding
The CATSLife project has been tracking individuals from infancy to the cusp of middle adulthood, with a total of 1,400 participants from the Colorado Adoption Project and the Longitudinal Twin Study. A five-year follow-up study, titled CATSLife2, has been awarded a grant of over $11 million to continue studying lifespan behavioral development and cognitive aging as individuals transition to mid-adulthood. The study aims to evaluate cognitive stability and change across the midlife transition and explore predictors of cognitive maintenance.
Conclusion
The Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging (CATSLife) is a unique study that aims to assess the unique saliency of early childhood genetic and environmental factors to adult cognitive maintenance and change. The study has already provided new insights into the complex interplay between genetic and environmental factors in shaping cognitive development and aging, and its findings have the potential to inform strategies for promoting healthy cognitive aging and preventing age-related cognitive decline.

Millennials are spending more than 60 hours a week sitting, and new research suggests that's a recipe for disaster, even if you're young and exercise regularly.
The University of Colorado Boulder study has shed new light on the alarming consequences of prolonged sitting in young adults. By analyzing data from the Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging, researchers have identified a significant association between prolonged sitting and increased risk of cardiovascular and metabolic disease. Notably, the study found that even young adults who engage in moderate physical activity may not be adequately mitigating the negative effects of prolonged sitting.
One of the most striking findings of this study is the concept of "sitting time equivalence." Essentially, this refers to the idea that prolonged sitting can have a similar impact on cardiovascular and metabolic health as aging itself. In other words, young adults who spend a significant amount of time sitting may be experiencing accelerated signs of aging, including increased risk of heart disease and metabolic disorders.
Furthermore, the study highlights the importance of vigorous physical activity in offsetting the negative effects of prolonged sitting. By engaging in at least 30 minutes of vigorous exercise per day, young adults may be able to reduce their risk of cardiovascular and metabolic disease by as much as 5-10 years. This finding has significant implications for public health policy and the development of evidence-based guidelines for physical activity.
The University of Colorado Boulder study serves as a stark reminder of the importance of incorporating physical activity into our daily lives, particularly in the face of increasingly sedentary lifestyles. As medical professionals and researchers, it is our responsibility to disseminate this critical information to the public and to advocate for policies that promote physical activity and reduce the burden of chronic disease.
Cognitive resilience refers to the ability of individuals to withstand and adapt to the challenges posed by genetic and environmental risks, ultimately maintaining optimal cognitive function across the lifespan. According to Chandra Reynolds' research, cognitive resilience is a critical factor in determining an individual's susceptibility to age-related cognitive decline and dementia.
Reynolds' work has shown that genetic influences contribute to frailty differences in early adulthood, which in turn are associated with worse performance on processing speed tasks. Furthermore, her research has found that an accelerated pace of aging, indexed by epigenetic aging, may lead to increased physiological vulnerability to stress, manifesting in higher frailty.
However, Reynolds' research also suggests that cognitive resilience can be developed and strengthened through various means. For instance, her work has found that moderate genetic influences contribute to cognitive function at shorter sleep durations, particularly for tasks such as semantic fluency and episodic memory. This implies that individuals can take steps to mitigate the negative effects of genetic and environmental risks on cognitive function by engaging in healthy behaviors, such as regular sleep and exercise.
Moreover, Reynolds' research highlights the importance of understanding the complex interplay between genetic and environmental factors in shaping cognitive resilience. By identifying the specific genetic and environmental risk factors that contribute to cognitive decline, researchers and clinicians can develop targeted interventions to promote cognitive resilience and prevent age-related cognitive decline.
Ultimately, the concept of cognitive resilience offers a promising avenue for the development of novel therapeutic strategies to prevent and treat age-related cognitive decline. By harnessing the power of cognitive resilience, we may be able to mitigate the impact of genetic and environmental risks on cognitive function, ultimately improving the quality of life for individuals and communities worldwide.
Ryan Bruellman, a Ph.D. candidate at the University of California, Riverside, is currently investigating the impact of prolonged sitting on health measures in young adults. His research interests lie at the intersection of nutrition, physical activity, genetics, and the environment, with a focus on understanding the complex relationships between these factors and their impact on human health.
Bruellman's current study is a critical examination of the consequences of spending most waking hours in a seated position, even among young adults who engage in regular physical activity. By analyzing data from the Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging, Bruellman is exploring the relationship between sitting time, physical activity, and health indicators such as body mass index (BMI) and total cholesterol/high-density lipoprotein ratio (TC/HDL).
One of the key aspects of Bruellman's research is the concept of "sitting time equivalence," which suggests that prolonged sitting can have a similar impact on health as aging itself. His study aims to shed light on the mechanisms underlying this phenomenon and to identify potential interventions that can mitigate the negative effects of prolonged sitting on health measures in young adults.
Bruellman's work has significant implications for public health policy and the development of evidence-based guidelines for physical activity. By understanding the impact of prolonged sitting on health measures in young adults, researchers and clinicians can develop targeted interventions to promote healthy behaviors and reduce the burden of chronic disease.
Furthermore, Bruellman's research highlights the need for a more nuanced understanding of the relationship between physical activity and health. While regular physical activity is widely recognized as a critical component of a healthy lifestyle, the study suggests that even among young adults who engage in regular physical activity, prolonged sitting can have significant negative effects on health measures.
Ultimately, Bruellman's research aims to contribute to a better understanding of the complex relationships between physical activity, sitting time, and health outcomes in young adults. By shedding light on the mechanisms underlying these relationships, his study has the potential to inform the development of novel interventions and policies that promote healthy behaviors and reduce the burden of chronic disease.
The study on prolonged sitting has significant policy implications that warrant attention from policymakers and public health officials. One of the most critical takeaways from this research is the need for policymakers to revisit physical activity guidelines to reflect the latest evidence on the risks associated with prolonged sitting.
Current physical activity guidelines often focus on the importance of regular exercise and physical activity, but they do not provide clear guidance on the risks associated with prolonged sitting. This study suggests that even young adults who engage in regular physical activity may be at risk for cardiovascular and metabolic disease if they spend too much time sitting.
Policymakers must consider the need to specify how much sitting is too much and to develop evidence-based guidelines that promote healthy behaviors. This may involve revising physical activity guidelines to include recommendations on reducing sitting time and incorporating more frequent breaks for physical activity throughout the day.
Furthermore, policymakers should consider the need to implement policies that promote physical activity and reduce sitting time in various settings, such as workplaces, schools, and communities. This may involve implementing policies such as standing desks, walking meetings, and active transportation options.
The study also highlights the need for policymakers to consider the social determinants of health and to develop policies that address the root causes of prolonged sitting, such as socioeconomic status and access to physical activity opportunities. By addressing these underlying factors, policymakers can help to reduce health disparities and promote health equity.
Ultimately, the policy implications of this study are clear: policymakers must take action to promote physical activity and reduce sitting time in order to prevent cardiovascular and metabolic disease in young adults. By working together, we can develop evidence-based policies that promote healthy behaviors and reduce the burden of chronic disease.
