“…Previous studies have shown a negative association between SA and BMD; consistent evidence has been reported in older adults [23,24]. A prospective study from Brazil found that increased sitting time was associated with decreased lumbar BMD in women [25]. A study from the UK of men in northeastern England also found a negative association between sedentary time and spinal BMD in men [23].…”

Summary We compared the relationship between sedentary activity (SA) and physical activity (PA) with bone mineral density (BMD) and body fat percentage in the United States and found a negative association between SA and BMD and a positive association with body fat percentage. a positive association between PA and BMD and a negative association with body fat percentage. Introduction SA and PA are associated with changes in skeletal parameters and body fat percentage, and we aimed to investigate and compare the relationship between SA, PA and bone mineral density (BMD) and body fat percentage in men and women. Methods We assessed the relationship between SA, PA and BMD and body fat percentage in 9249 Americans aged 20-80 years (mean age 38.26 ± 11.39 years) from NHANES 2011-2018.BMD and body fat percentage were measured by dual-energy X-ray bone densitometry (DXA). We used multiple linear regression models to examine the relationships between SA, PA and total BMD and total body fat percentage, adjusted for a large number of confounding factors. Results After adjusting for race/ethnicity, age, alcohol and smoking behavior, body mass index (BMI), total protein, blood calcium, blood uric acid, cholesterol, blood phosphorus, and blood urea nitrogen, SA was negatively associated with total BMD (β =-0.002 95% CI: -0. 003-0.001, P < 0.001) and SA was positively associated with total lipid percentage (β =0.149 95% CI: 0.111-0.186, P < 0.001). There was a positive correlation between multiple PAs and BMD and a negative correlation between multiple PAs and percent body fat. Conclusions Our results show that physical activity is a key component of maintaining bone health in both men and women and is strongly associated with lower body fat percentages. Sedentary activity has deleterious effects on skeletal homeostasis and is strongly associated with increased body fat percentage. Healthcare policymakers should advise people to be less sedentary and more physically active in the prevention of osteoporosis and obesity.

“…As such from a public health perspective, another consideration is sedentary breaks (how many per day, how often, for how long) and sedentary bouts. It has been reported that older women may benefit more from shorter sedentary bouts when it comes to spine BMD 28 , but the possible effect of this strategy has not been tested widely and thus requires further investigation.…”

Introduction: Understanding daily movement patterns (i.e., the relative proportion of time spent on Sedentary behaviour (SB), light physical activity (LPA), moderate-vigorous physical activity (MVPA) and sleep) to establish links with chronic diseases is a contemporary topic. Little research has looked at the effects of 24-hour movement behaviour on bone health (particularly bone mineral density (BMD)) despite investigation on other health parameters. The aim of this rapid narrative review was to build on previous work published on the association between SB and BMD in older adults by investigating the association of the more holistic 24- hour movement behaviours in relation to BMD. Methods: A database search of Web of Science and NIH PubMed was conducted using broad MeSH terms (older adults, sedentary, and bone). Searches were limited from the year 2019 onward. Results/Discussion: Five published articles were reviewed, and there are discrepancies amongst the findings which could be attributed to the different measurement methods (Peripheral Quantitative Computed Tomography (pQCT) versus Dual-energy X-Ray Absorptiometry (DEXA)) and the sites of measured BMD. There are also notable differences between genders, with BMD in men appearing to be most reliant on time spent in MVPA, compared to women who appear to see benefit to BMD with replacement of SB with LPA and not require more time spent in MVPA. This highlights the complexity of movement behaviours and requires further research.

We compared the relationship between sedentary activity (SA) and physical activity (PA) with bone mineral density (BMD) and body fat percentage in the United States and found a negative association between SA and BMD and a positive association with body fat percentage. A positive association between PA and BMD and a negative association with body fat percentage. SA and PA are associated with changes in skeletal parameters and body fat percentage, and we aimed to investigate and compare the relationship between SA, PA and bone mineral density (BMD) and body fat percentage in men and women. We assessed the relationship between SA, PA and BMD and body fat percentage in 9787 Americans aged 20–59 years (mean age 38.28 ± 11.39 years) from NHANES 2011–2018. BMD and body fat percentage were measured by dual-energy X-ray bone densitometry (DXA). We used multiple linear regression models to examine the relationships between SA, PA and lumbar spine BMD and total body fat percentage, adjusted for a large number of confounding factors. After adjusting for race/ethnicity, age, alcohol and smoking behavior, body mass index (BMI), total protein, blood calcium, blood uric acid, cholesterol, blood phosphorus, vitamin D, and blood urea nitrogen, SA was negatively associated with lumbar spine BMD (β = − 0.0011 95% CI − 0.0020 to − 0.0002, P = 0.022), and SA was positively associated with total fat percentage (β = PA was positively associated with lumbar BMD (β = 0.0046 95% CI 0.0010 to 0.0082, P = 0.012) and there was a negative association between PA and body fat percentage (β = − 1.177 95% CI − 1.326 to –1.027, P < 0.001). Our results show that physical activity is a key component of maintaining bone health in both men and women and is strongly associated with lower body fat percentages. Sedentary activity is negatively correlated with bone density and is strongly associated with an increase in body fat percentage. Healthcare policy makers should consider reducing sedentary activity and increasing physical activity when preventing osteoporosis and obesity.
