Hair Calcium Concentration is Associated with Calcium Intake and Bone Mineral Density

Calcium concentration in hair, representing intracellular calcium levels, is associated with systemic diseases such as coronary artery disease. To date, there are no previous studies which investigate the regulation of hair calcium levels. The aim of the study is to investigate whether hair calcium concentration is related to calcium intake and calcium content in bone - bone mineral density (BMD). An observational research study was conducted with 55 women over the age of 20 who visited a university hospital in Suwon, Korea. The average age of the women was 51.45. Depending on the concentration of hair calcium, participants were divided into quartiles to compare calcium intake and BMD. There was no difference in demographic, anthropometric, and biochemical characteristics between the highest quartile of hair calcium concentration and the rest of the quartiles. However, the highest quartile ingested significantly less calcium compared to the rest of the quartiles (p < 0.05). The highest quartile of hair calcium concentration also showed significantly lower BMD and T-score in the L1 - 4 vertebrae compared to the rest of the quartiles (p < 0.05). These results show that high hair calcium concentration was associated with low calcium intake and low BMD.

Background: This paper is aimed at assessment of bone health in women aged between 19-35 years in the urban area leading a sedentary lifestyle. The objective of the study was to assess the bone density among the adult women and identify their risk of developing osteoporosis and to associate risk factors that may predispose them to osteoporosis.Methods: The methodology involved assessment of their anthropometric measurements and calculating Body mass index to identify obese and non-obese participants. A semi-quantitative food frequency questionnaire was framed to know the calcium intake of the diet along with the other nutrients and foods that favour and hinder the absorption of calcium was also studied along with their frequency of consumption. BMD test on all 51 participants is done and the T- score obtained compared with the WHO classification.Results: It was observed that 35% of the participants were having osteopenia, a condition where bones become weak than normal and may predispose to osteoporosis. The calcium content of the diet found to be lower than the RDA which is significant at p<0.05. Correlation analysis showed a weak negative correlation between the two variables i.e., calcium intake and bone mineral density rs=-0.03, p>0.05. Other factors that can contribute to the low bone mineral density was lack of exercise, obesity, genetic inheritance, H/o PCOS, hypothyroidism, consumption of coffee and carbonated beverages.Conclusions: Thus, it is concluded that these women are at risk of developing osteoporosis so dietary modification and change in lifestyle is necessary.
