AI Article Synopsis
- This study investigates the interplay between genetic factors, specifically polygenic risk scores (PRS), and lifestyle choices, particularly coffee and caffeine intake, in relation to osteoporosis in middle-aged adults.
- Researchers analyzed data from 8,845 participants, identifying gene interactions that significantly influenced osteoporosis risk, with a notable 1.71-fold increase in risk linked to high PRS.
- Findings suggest that individuals with a high PRS for osteoporosis are at greater risk if they consume low amounts of coffee and caffeine, indicating potential for personalized dietary recommendations to help mitigate osteoporosis risk.
Article Abstract
Objectives: Osteoporosis is associated with genetic and environmental factors. The aim of this article was to determine how the polygenic risk scores (PRS) of genetic variants that affect osteoporosis and its related signaling interact with the lifestyle of middle-aged adults.
Methods: The study examined 8845 participants from Ansan/Ansung cohorts. Osteoporosis was defined as a T-score of bone mineral density ≤-2.5 in either the wrist or tibia; 1136 participants had osteoporosis. Genome-wide association studies of individuals 40 to 65 y of age were conducted and the best gene-gene interactions from the genetic variants related to osteoporosis were selected and explored using the generalized multifactor dimensionality reduction method. PRS for the best model (PRSBM) was calculated by weighted PRS that was divided into low, medium, and high groups.
Results: The model that contributed the most influence on osteoporosis risk with gene-gene interactions included AKAP11_rs238340, KCNMA1_ rs628948, PUM1_rs7529390, SPTBN1_ rs6752877, and EPDR1_rs2722298. The risk for osteoporosis in the tibia was elevated by 1.71-fold in the high PRSBM group compared with the low PRSBM group. Energy and nutrient intake did not have any interaction with PRSBM and thus did not influence risk for osteoporosis. However, interestingly, only coffee and caffeine intake did interact with PRSBM and affected risk for osteoporosis. In patients with low coffee (<3 cup/wk) and caffeine(<60 mg/d) consumption, osteoporosis risk was higher in the high PRSBM group than the low PRSBM group by 2.27- and 2.29-fold, respectively. In the low coffee intake group, bone mineral density in the high PRSBM group was significantly higher than in the low PRSBM arm.
Conclusions: Carriers with high PRSBM increased susceptibility to osteoporosis, especially in low coffee and caffeine intake. The results can be applied to personalized nutrition for lowering the risk for osteoporosis.

Background: Subclinical vitamin D insufficiency is frequent in both developing and developed countries. Even after rickets was eliminated in the 1930s by fortifying milk, up to 1 billion people worldwide suffer from subclinical vitamin D deficiency (VDD). Numerous noncommunicable diseases (NCDs), including depression, autoimmune illnesses, diabetes, osteoporosis, and cardiovascular disease, are linked to this deficiency.

The Cayo Santiago rhesus macaque colony is a renowned primate population that has experienced significant natural and anthropogenic ecological variation in their 85-year history. Demographic and familial information is also tracked and collated for the majority of monkeys. Thus, the health history of rhesus macaques at Cayo Santiago should reflect the impacts of both environmental and genetic factors.

Unlabelled: In patients receiving long-term treatment with denosumab, denosumab discontinuation via sequential treatment with zoledronate, resulted in a minor decrease in bone mass density (BMD) of 0-2.5% within the first year and stabile BMD in the second year, thus showing that repeated treatments with zoledronate limit the loss of BMD, when discontinuing denosumab.
Purpose: Discontinuing denosumab (DMAb) rapidly decreases bone mineral density (BMD) and increases the risk of multiple vertebral fractures.

Unlabelled: Most subjects in osteoporosis clinical trials were women with postmenopausal osteoporosis and while bridging studies (BMD endpoint) provide an expectation that osteoporosis medications will reduce fracture risk in men. This real-world study shows direct evidence of fracture risk reduction among men with osteoporosis (36% of hip fracture reduction with denosumab).
Purpose: Direct evidence for fracture risk reduction of medications used among men with osteoporosis is very limited.

Type 1 diabetes (T1D) represents a significant health burden worldwide, with associated complications including bone fragility. Current clinical methods and biomarkers for assessing bone health and predicting fracture risk in T1D are limited and lack accuracy. MicroRNAs (miRNAs) have emerged as potential biomarkers for predicting T1D-induced bone loss, although comprehensive profiling studies are lacking.
