Factors influencing the use of contraceptives through the lens of teenage women: a qualitative study in Iran

Abstract Background One out of seven teenage girls in developing countries marries before the age of 15. While the fertility rate of teenage girls is high, the rate of contraceptive use remains low; therefore, this group of teenagers needs reproductive healthcare. This study was undertaken to explore factors influencing the use of contraceptives from the perspective of teenage women living in the city of Ardabil in Iran. Methods This qualitative study was conducted with 14 married women aged 13–19 years who attended in urban-rural healthcare centers in Ardabil. Eligible women were recruited using purposive sampling and were invited to take part in individual in-depth semi-structured interviews. The duration of the interviews varied from 45 to 90 min with an average of 55 min. Sampling continued until data saturation was reached and no new data was collected. Each interview was tape-recorded after obtaining the participant’s permission, transcribed verbatim and analyzed for identifying categories and themes using conventional content analysis. Results Three themes and eight subthemes were developed. The themes were as follows: “insufficient familiarity with contraceptive methods”, “pressure to become pregnant” and “misconceptions”. Conclusion Despite the high prevalence of early marriage in Iranian society, teenage women are not empowered or prepared for marriage and birth control. Sexual and reproductive healthcare services to teenage women should be improved to meet their needs

The effects of vitamin D supplementation on indices of glycemic control in Iranian diabetics: A systematic review and meta-analysis

Background and purpose: This systematic review and meta-analysis aimed to assess the effects of vitamin D supplements on indices of glycemic control [homeostatic model assessment-insulin resistance (HOMA-IR), hemoglobin A1C (HbA1C), fasting blood glucose (FBG), and quantitative insulin-sensitivity check index (QUICKI) and lipid profile in diabetic patients. Methods: Eight databases were searched, for randomized controlled trials (RCTs) or cross-sectional and cohort studies that have been published up to December 2017. We used the comprehensive meta-analysis (CMA) software for all statistical analysis and used the I 2 index for assessing heterogeneity. A p value of <0.05 was considered as statistically significant. Results: We found 621 articles, and after the exclusion of ineligible publications, 82 studies remained to be assessed of which 37 were used for meta-analysis. Vitamin D supplementation was associated with a significant improvement in FBG (p = 0.001 and 95% CI: −0.526 to −0.136) and HbA1C (p = 0.003 and 95% CI: 1.719 to −0.361) in individuals with type 2 diabetes mellitus (T2DM); while in women with gestational diabetes mellitus (GDM) the reduction in FBG (p = 0.071 and 95% CI: −0.873 to −0.035) and HbA1C (p = 0.199 and 95% CI: 3.270 to 0.681) failed to reach statistical significance. Treatment with vitamin D supplements was associated with an improvement in HOMA-IR in pregnant diabetic women (p = 0.028 and 95% CI: 0.924 to −0.053) and for individuals with diabetes mellitus (p = 0.005 and 95% CI: 1.772 to −0.319). The pooled result of the cross-sectional meta-analysis indicated that serum vitamin D concentrations were significantly lower in diabetic patients than in healthy controls (p = 0.018 and 95% CI: 0.587 to −0.054). Conclusion: This meta-analysis suggests that vitamin D supplementation improves indices of glycemic control (FBG, HOMA-IR, and HbA1C) in patients with diabetes mellitus. Hence, vitamin D supplements may be of potential therapeutic value in diabetic patients, as an adjuvant therapy along with other treatment
