The findings suggest that nutritional/metabolic support may have therapeutic benefit in specific patients hospitalized with heart failure.
A study of 8,404 children found that those with obesity used more healthcare resources and had higher charges than their healthy-weight counterparts. The average adjusted difference in charges was $172 for children with diagnosed obesity.
Women with higher physical activity levels have a lower risk of developing breast cancer, especially for estrogen receptor-positive/progesterone receptor-negative tumors. Physical activity reduces body fat, leading to lower estrogen levels and potentially decreasing ER+/PR+ tumors.
Research suggests that higher body mass index (BMI) in early adulthood is associated with a reduced risk of breast cancer before menopause. This protective effect is not linked to ovulation problems, and the association persists even when adjusting for other factors such as family history and lifestyle habits.
Researchers found that Minnesotans in the Twin Cities metro area are expending a significantly greater amount of energy participating in moderately intense physical activities than they were five years ago. The majority of this energy expenditure came from leisure-time physical activities such as walking, running, or biking.
