In long - term studies, researchers have found that regular participation in weight - bearing exercise, leads to a significant increase
in bone mineral content.
The relationship between diet and
bone mineral content of multiple skeletal sites in elderly Japanese - American men and women living in Hawaii
Among stimulant users, the average
bone mineral content at the lumbar spine was 5.1 percent lower than in nonusers and 5.3 percent lower at the hip, the investigators reported.
For all three groups, researchers
measured bone mineral content and density in the spine, neck, hip and the whole body, and looked at current height and weight, smoking, level of physical activity and a variety of other measures.
Anthropometrics and formula intake were determined monthly; total
body bone mineral content (BMC) and bone mineral density (BMD) were measured at baseline, 3, and 6 months of age using dual energy x-ray absorptiometry.
Those who consistently watched ≥ 14 hours / week of television had
lower bone mineral content than those who watched less television, even after adjusting for height, body mass, physical activity, calcium intake, vitamin D levels, alcohol, and smoking (all at age 20).
The DXA scans evaluated bone mineral density, a surrogate measurement of bone strength, as well
as bone mineral content, which is the weight of bone, at both the hip and the lumbar spine (lower back).
Children with drug resistant epilepsy are at risk of insufficient vitamin D status prior to starting ketogenic therapy (3) and although levels can be normalised with vitamin D supplementation, a decline in both whole body and
spine bone mineral content while on the ketogenic diet has been reported (4) despite reduction in anticonvulsant medication.
The study, which appears in the May issue of Pediatrics - the official journal of the American Academy of Pediatrics - was conducted at Hutzel Hospital at Wayne State University in Detroit, Michigan in the US and examined the difference
in bone mineral content and density in children who had received infant formula containing palm olein oil as compared to those who received infant formula without the oil.
She said prospective research studies that evaluate bone density and
bone mineral content at more than one point in time are needed to clarify the effects of stimulant medications on the skeleton of growing children.
In fact,
the bone mineral content is greater in childhood follow - ups in direct proportion to the amount of human milk received.
[Fully human milk - fed preemies experienced slightly slower growth and lesser early
bone mineral content but no reduction in head circumference; an indicator of brain development.]
Soluble CD14 levels were inversely correlated with measures of
bone mineral content and density, suggesting macrophage activation as a possible mechanism for such bone loss.
«However,
bone mineral content and density increase as we grow, then decline at a fairly steady rate once we reach adulthood — making it a potentially useful way of assessing age,» Ross says.
Bone mineral content and density in adulthood depends predominantly on growth and mineralization and the peak bone mass achieved in early adulthood.
The proof - of - concept study involving 25 mothers and infants provides preliminary evidence that even fructose equivalent to the weight of a grain of rice in a full day's serving of breast milk is associated with increased body weight, muscle and
bone mineral content.
Bone mineral content is a better measure of bone health in children than is bone mineral density, Feuer stated.
The study looked at the bone mineral density (BMD) and
bone mineral content (BMC) of 1107 children at birth and at four and / or six years of age and compared the data to the number of supermarkets, healthy specialty stores and fast food outlets within a child's neighbourhood.
The bone mineral content and bone mineral density of the femur were significantly higher in the group given 6 percent casein plus 4 percent gelatin.
The bone mineral content of smokers is 15 - 30 % lower in women and 10 - 20 % lower in men.
Few studies have looked at whether magnesium intake and absorption are related to
bone mineral content in young children.
Participants in the standard intervention and enhanced intervention groups did not differ significantly for fat mass, lean mass, percent body fat,
bone mineral content, bone mineral density, or cardiorespiratory fitness (P ≥.05 for all), although there were significant changes across time among all participants (P <.01 for all for time).
