Abstract
The high prevalence of osteoporosis in Pakistan is of public-health concern. However, there is a paucity
of information regarding nutrition and bone density in rural communities. The purpose of this study was
to evaluate the dietary and lifestyle factors that impact bone health in Nahaqi. Data were collected from
140 postmenopausal women using an interviewer-administered 24-hour dietary recall questionnaire. Bone
mineral density was estimated using the quantitative ultrasound index (QUI). Serum 25(OH)D was measured
in fasting blood samples. The QUI scores revealed that 42% and 29% of the women had T-scores,
indicative of osteopaenia and osteoporosis respectively. The mean calcium intake was 346 mg/d, which
is less than 50% of the recommended daily intake. The QUI correlated with 25(OH)D after controlling for
age (p=0.021, r=0.41, r2=0.168). Vitamin D deficiency and low intake of dietary calcium are two key factors
contributing to poor bone health in this population.
