Dietary Calcium Intake in Young Bangladeshi Female Garment Factory Workers: Associations with Serum Parathyroid Hormone Concentrations

The association of low calcium intake with high serum PTH concentrations, increased
bone resorption and low bone mass has been studied extensively in elderly women
but studies examined the association among young women of childbearing age are
scanty. The present study was designed to evaluate the dietary intake of calcium
and its association with intact parathyroid hormone (S-iPTH) in young female
garment factory worker with hypovitaminosis D. A total of 198 apparently healthy
subjects (aged 18-36 years) were randomly selected. Anthropometric and background
information was collected. Three days dietary records were used to estimate
habitual calcium intake. Serum concentrations of 25-hydroxyvitamin D (S-25OHD)
and S-iPTH were measured. The dietary calcium intake was uniformly low. About
60% of subjects failed to meet the lowest level (400 mg day-1) of
Recommended Dietary Allowances (RDA) of calcium for Indian adult women. S-iPTH
showed a significant inverse relationship with dietary calcium intake (r = -0.60,
p<0.001). We observed that dietary calcium intake and S-25OHD together explained
46% of the variation in S-iPTH and 39% of the total variability in S-iPTH was
explained by the variation in dietary calcium intake alone. Low calcium intake
could reduce the bone accretion and may increase the risk of hyperparathyroidism,
osteoporosis and fracture burden in these subjects.
