Effectiveness of intervention using calci-D and communication for preventing osteoporosis in low bone density person in HCMC 2011-2013

Abstract

    An interventional study which is not controlled (quasi experimental) was conducted on 166 people aged 45 and older who had low bone density in 4 wards and communes in Ho Chi Minh City (HCMC). The interventions were health education and communication measures to increase knowledge and practice, and enhance proper nutrition, physical exercise, calcium-D supplements daily for 2 years (2011-2013) to improve the bone mineral density (BMD). BMD was measured by DXA method (Dual Energy X-ray absorptiometry) at the wrist and osteoporosis was diagnosed according to WHO standards. Results showed, after intervention, that BMD average increased by 0.006 g/cm²; Rate of osteoporosis decreased by 13.3, 20.4% efficiency index; Good knowledge increased 37.4%, 364.3% efficiency index; Good practice increased by 56.6%, 1347.6% efficiency index. Thus, rengthening behavior change communication combined with Calcium-D supplements daily will improve the bone density and increase beneficial behaviors for bone health in middle-age or older people who have low BMD.
