Low testosterone tied to increased risk for mortality, CVD events.

Men with low testosterone levels face a higher risk of all-cause mortality, and those with very low testosterone have an increased risk of cardiovascular disease (CVD) mortality, according to a study published in the Annals of Internal Medicine.

Given the effects of testosterone on male libido, virilization, and body composition ... an important question has been whether and when lower endogenous testosterone concentrations are related to poorer health outcomes,” Bu B. Yeap, MBBS, a professor in the Medical School at the University of Western Australia, and colleagues wrote.

Yeap and colleagues further reported that lower sex hormone-binding globulin (SHBG) concentrations were associated with reduced risks of all-cause mortality (adjusted hazard ratio [HR] = 0.85; 95%confidence interval [CI], 0.77-0.95) and cardiovascular disease (CVD)mortality (a HR = 0.81; 95% CI, 0.65-1).

Itis possible that higher SHBG concentrations could modulate the bioavailability of testosterone to tissues,” they noted. “Alternatively, SHBG might influence risk for all-cause and CVD mortality in a manner distinct from its relationship with total testosterone, but further investigation of potential underlying nutritional or metabolic pathways would be needed.”

Further investigation into potential underlying mechanisms for these associations is warranted,” Yeap and colleagues concluded.

Physical Activity Helps Ward Off Inflammatory Bowel Disease, Meta-Analysis Shows.

Higher levels of physical activity are linked to a reduced risk of developing inflammatory bowel disease (IBD), especially Crohn's disease (CD).

Individuals with high physical activity levels had a 22% reduced risk of developing Crohn's disease (CD) in cohort studies and a 38% reduced risk in case-control studies compared to those with low physical activity levels.

The risk of incident ulcerative colitis (UC) was 13% lower in the high physical activity group versus the low physical activity group in cohort studies, although this reduction did not reach statistical significance in case-control studies.

The quality-of-evidence assessment found no serious limitations in the cohort studies but identified serious limitations in the case-control studies due to a high risk of bias and significant heterogeneity.

"There could be a role of physical activity as a prevention strategy against developing IBD. In addition to implementing public health interventions to increase physical activity level, there may be a place for physicians to advise increased physical activity level, especially to individuals at high risk of developing IBD, such as those with a strong family history of IBD," the authors wrote.

Living Near Green Spaces Could Strengthen Your Bones. 

Living close to trees and other greenery could help keep your bones strong, according to a new 12-year study.

Chinese researchers found that people living near "green" areas, as identified by satellite imagery, tended to have better bone density than those living in less green areas. The study, led by Zhengxiao Ouyang from Central South University in Changsha, highlighted that reductions in air pollution might be key to this benefit.

The study analyzed data from over 391,000 British participants tracked by the UK Biobank database. The participants had an average age of 56, with 53% being women. In addition to bone mineral density and genetic risk for osteoporosis, the Biobank data included information on diet, smoking status, income, exercise levels, and other factors.

"These findings provide valuable insights into the potential of greenness in preventing the onset of osteoporosis and emphasize the significance of urban greening in developing effective prevention strategies," Ouyang's team said.
