Physical activity levels among young adults are on the decline, according to a recent study conducted by researchers at Queensland University of Technology. The study, published in PLOS ONE, analyzed the physical activity habits of 2 million American adults between 2011 and 2019. Led by David Abernethy and Associate Professor Toby Pavey, the study found a concerning trend of decreasing physical activity levels among young adults.
The researchers noted that while previous studies have shown a decline in physical activity with age, the unexpected decrease among young adults raises red flags. One possible explanation for this decline is the increased accessibility and reliance on sedentary behaviors associated with the expansion of digital media. The rise in screen time among young adults has been linked to a decrease in physical activity, as more time is spent on sedentary activities.
Despite the decline in physical activity levels, the study found that approximately half of U.S. adults reported sufficient moderate-vigorous activity. Meeting the recommended 150 minutes of moderate to vigorous intensity physical activity each week has been shown to significantly improve well-being and reduce the risk of chronic disease and premature death. Moderate-intensity physical activity allows for conversation, while vigorous-intensity physical activity causes huffing and puffing, making it harder to talk.
The study also highlighted disparities in physical activity levels based on gender, education level, smoking status, BMI, and dietary habits. Men were found to be more likely to be physically active than women, and individuals with higher levels of education, normal BMI, and healthy dietary habits were more likely to meet physical activity guidelines.
The researchers identified key priority groups for increasing physical activity, including young adults, women, lower-educated populations, people living with obesity, and individuals with chronic diseases and mental health conditions. Tailored interventions and accessible physical activity programs are needed to address the declining physical activity levels among these populations.
In conclusion, the study underscores the importance of promoting physical activity across all segments of the population. By understanding trends in physical activity levels and identifying factors that contribute to sufficient activity, public health campaigns can be more effectively targeted to improve overall well-being and reduce the risk of chronic diseases.
