Project Aim/ Objectives
Aim
The study aims to assess the relationship between bone density and hormonal contraceptive users


Objectives
To explore whether the use of progestin injectable or combined oral contraceptives, when compared to non-use, is associated with an increase, decrease or no change in bone mass among women aged 15-19 years and 41-49 years

Project Activities

  • The study was conducted at a large family planning clinic in central Durban.
  • Recruitment began in July 2000
  • The study collects information via questionnaires and physical measurements that include bone mineral density, weight, height and blood pressure

Anticipated/Actual Results

  • The study has completed data collection
  • Update report have been produced as required.
  • The analysis of the cross sectional data has been completed and a full descriptive report on the descriptive data for the cohort has been produced.
  • A interim analysis was submitted on the younger women in June to the WHO bone health meeting
  • The final results of this study are anticipated to answer crucial issues around possible effect of different hormonal contraceptives on bone mass
  • Findings will be used to make policy recommendations related to the use of these methods in the two age groups.
  • Final data analysis is underway
