Evaluation of Lifestyle and Some Biochemical Parameters Involved in Bone Health in Pre and Postmenopausal Cameroonian Women

Abstract

Aims: A healthy skeletal system with strong bones is essential to overall health. This study aimed to assess lifestyle and bone’s biomarkers of women.
 Study Design: This was a cross-sectional study.
 Place and Duration of Study: The enrollment took place at the Yaounde Military Hospital from November 2016 to July 2017.
 Methodology: A set of 105 postmenopausal and 127 premenopausal participants were enrolled from November 2016 to July 2017 in Yaounde. Their physical activities level was evaluated using a questionnaire. Sunlight exposure between 10:00AM and 4:00PM was assessed. Colorimetric methods were used to evaluate calcium, albumin, and alkaline phosphatase activity in plasma. These parameters were then compared within year since menopause (YSM) and osteoporosis risk assessment instrument (ORAI) sub-groups.
 Results: 13.4% participants were moderately active. Only 22.8% participants had at least 30 minutes sun exposure daily. A multivariable analysis of demographic, lifestyle, biochemical characteristic revealed age, BMI, albumin and calcium were the main factors that influenced bone health among our participants. A significant difference of calcium concentration was found between the two groups whereas albumin was significantly higher in premenopausal than postmenopausal. Albumin was the only variable with a significant difference in the YSM sub-groups while only calcium was non-significantly higher among the ORAI sub-groups.
 Conclusion: Elevated plasma level of calcium, albumin and alkaline phosphatase could be indicators of high bone turnover.
