But low BMD in female offspring as only related to that of her mother - interesting
Wonder if that is due to how the body deals with such things as Vitamin D, Magnesium, Calcium
The items in both of the categories of Infant-Child and Bone Health are listed here:
- Breastfed infant bones not helped by 800 IU of Vitamin D (not enough) – RCT Dec 2017
- Large soft spot on infant’s head (anterior fontanelle) is associated with low vitamin D – Sept 2017
- Long-Term bedridden patients have poor vitamin D and poor bones – June 2017
- Low bone mineral density of male children is associated with low BMD of parents – Oct 2016
- Childhood Fractures – consensus report on vitamin D – Feb 2016
- 2,000 IU vitamin D recommended for pediatric rheumatology – May 2015
- Low vitamin D during pregnancy associated with four health problems in children – Jan 2015
- Child Bone health – (incorrect) recommendations by US Pediatric and Bone Health groups – Sept 2014
- Hip problem in boys (PERTHES' DISEASE) associated with low vitamin D – Jan 2014
- Low vitamin D associated with 5.5X increased risk of low bone mineral density – March 2013
- Bone health markers generally not improved by 550 IU of vitamin D after birth – July 2012
- Less child bone if mother lacked vitamin D – Dec 2010
- Lack of vitamin D in infants can result in broken bones and shaken baby syndrome - March 2010
Bone mineral density (BMD) of offspring was significantly associated with their parents' BMD. Parental BMD Z-score =-1 was a significant predictor for BMD Z-score =-1 in their offspring. Peak bone mass acquisition during early adulthood is more substantially influenced by genetic factors rather than lifestyle or environmental factors.
A person's BMD is affected by both genetic and environmental factors. Family history of osteoporosis or fragility fracture is a well-known risk factor for low bone mass or fracture. The purpose of the present study was to investigate the familial association of BMD between parents and offspring in Korean population.
This is a cross-sectional study based on the data from the Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2008 to 2011. A total of 5947 subjects (3135 parents and 2812 offspring) were included.
In age-adjusted partial correlation analyses, all BMD values acquired from the lumbar spine, femur neck, total hip, and whole body showed significant associations between parents and offspring. Among these associations, whole-body BMD showed the strongest relationship between offspring and parents. The narrow-sense heritability of BMD ranged from 0.203 to 0.542 in male offspring and from 0.396 to 0.689 in female offspring. Multiple linear regression analyses showed that offspring's BMD was independently associated with BMD of both parents after adjusting for covariates. Lifestyle or environmental factors including dietary calcium intake, serum 25-hydroxyvitamin D level, regular exercise, current smoking, and alcohol intake showed only moderate or no associations with BMD. In multiple logistic regression analyses in offspring aged 19-25 years, the son's risk of having BMD Z-score =-1 was associated with both parents' BMD Z-score =-1, while the daughter's risk was only associated with maternal BMD Z-score =-1.
Our findings confirm the strong familial association of BMD between parents and offspring in Korean population and suggest that peak bone mass acquisition during early adulthood is more substantially influenced by genetic factors rather than lifestyle or environmental factors.
