Contraceptive and reproductive health practices of unmarried women globally, 1999 to 2018: Systematic review and meta-analysis

A comparative study of hormonal contraceptive use and vitamin D levels at Gondar Town 2023

Vitamin D deficiency is an emerging public health problem globally, with devastating health consequences. Some studies suggest that exogenous sex hormones, found in hormonal contraceptives, may enhance vitamin D levels. However, the reasons for this association are not fully understood, as women using hormonal contraception may have different lifestyle habits affecting their vitamin D status. Therefore, this study seeks to explore the relationship between hormonal contraceptive use and vitamin D levels. A Facility based comparative cross-sectional study was conducted in Gondar town from February to April 2023, involving a total of 162 women using three types of hormonal contraceptives (Norplant, DMPA, and COC) and 162 age and BMI-matched non-users as controls in a 1:1 ratio. Participants were selected using systematic random sampling. A semi-structured questionnaire was used to collected data regarding the socio-demographic, economic, obstetric, lifestyle, and clinical information. 5 milliliters of blood samples were collected from each participant for Laboratory analysis of serum vitamin D, calcium, and alkaline phosphates using a Beckman Coulter chemistry analyzer. Independent t-tests, ANOVA with post hoc Bonferroni test was used to compare statistics between the two groups, and logistic regression models to identify factors associated with Vitamin D deficiency. The mean serum Vitamin D levels of Norplant, DMPA, and COC users were 24.08 (± 5.17), 24.83 (± 5.52), and 31.90 (± 6.94) respectively; whereas control group has mean Vitamin D level of 22.00 (± 7.97). On the current study the prevalence of Vitamin D deficiency (< 20 ng/ml) among hormonal contraceptive users was found to be 21.6% (35/162), whereas 48.14% (78/162) of non-user controls had vitamin D deficiency. The odds of having Vitamin D deficiency was higher among participants who attained higher education, who never eat fish and have never been used vitamin D Supplements. However, the use of combined oral contraceptives (COC) shown to reduce the odd of having vitamin D deficiency by 90%. Similarly, individuals with normal and hypercalcemia state shown to have lower odd of having Vitamin D deficiency. Users of combined oral contraceptives (COC) had significantly higher mean serum Vitamin D levels compared to users of Norplant and DMPA, as well as non-users. The prevalence of Vitamin D deficiency was lower among COC users compared to non-users, highlighting a potential protective effect of COC use against Vitamin D deficiency.

Access to quality contraceptive counselling among adolescent girls and young women in sub-Saharan Africa

BACKGROUND

Improving women's access to and use of modern contraceptives is a key global strategy for improving the sexual and reproductive health of women. However, the use of modern contraceptives among adolescent girls and young women in sub-Saharan Africa (SSA) remains relatively low, despite the numerous interventions to increase patronage. This study examined adolescent girls and young women's receipt of quality contraceptive counselling and its associated factors in SSA.

METHODS

Data for the study were extracted from the recent Demographic and Health Surveys of 20 countries in SSA, spanning from 2015 to 2021. A sample of 19,398 adolescent girls and young women aged 15 to 24 years was included in the study. We presented the proportion of adolescent girls and young women who received quality contraceptive counselling using a spatial map. Multilevel binary logistic regression analysis was carried out to examine the factors associated with the receipt of quality contraceptive counselling.

RESULTS

Overall, 33.2% of adolescent girls and young women had access to quality contraceptive counselling, ranging from 13.0% in Cameroon to 67.0% in Sierra Leone. The odds of receiving quality contraceptive counselling was higher among adolescent girls and young women aged 20-24 (AOR = 1.48, CI: 1.32-1.67), those with primary (AOR = 1.32, CI: 1.11-1.57) and secondary or higher education (AOR = 1.31, CI: 1.09-1.58), and those married (AOR = 1.32, CI: 1.15-1.52), cohabiting (AOR = 1.47, CI: 1.23-1.76), and previously married (AOR = 1.48, CI: 1.20-1.83) compared to their counterparts in the reference groups. Adolescent girls and young women who were currently working (AOR = 1.22, CI: 1.09-1.37), those who heard of family planning from radio in the last few months (AOR = 1.34, CI:1.21-1.50), those who visited the health facility in the last 12 months (AOR = 1.69, CI: 1.52-1.88), and those residing in the Southern (AOR = 5.01, CI: 3.86-6.51), Eastern (AOR = 2.54, CI: 1.96-3.30), and Western (AOR = 4.09, CI: 3.19-5.25) SSA were more likely to receive quality contraceptive counselling compared to their counterparts in the reference groups. Conversely, adolescent girls and young women who used the internet, those who had problem getting permission to seek medical help, those facing problem in seeking medical help for not wanting to go alone, those from the middle and richest wealth indices, and those from the rural areas were less likely to receive quality contraceptive counselling compared to their counterparts in the reference groups.

CONCLUSION

Receipt of quality contraceptive counselling among adolescent girls and young women was low. Considering the importance of quality contraceptive counselling on the uptake and continuation of contraception, policymakers need to institute measures that improve adolescent girls and young women's access to quality contraceptive counselling in SSA, especially in countries like Cameroon, Angola, Madagascar, Mauritania, and Guinea, taking into consideration the factors identified in the study. Increasing adolescent girls and young women's access to quality contraceptive counselling could greatly minimize the risk of unintended pregnancies and its associated maternal and child health burden in SSA and subsequently contribute to the attainment of the Sustainable Development Goal 3, target 3.7.

Sexual behaviors and condom use in the Brazilian population: analysis of the National Health Survey, 2019

OBJECTIVE

The objective of this research was to describe the sexual behaviors and condom use in the Brazilian population.

METHODS

This is a cross-sectional, descriptive study, which used data from 88,531 individuals aged 18 years old or older, who answered the second edition of the National Health Survey carried out in 2019. Prevalence was estimated with the respective 95% confidence intervals for each sexual behavior indicator and condom use according to gender, age, race/skin color, educational level, and region of residence.

RESULTS

The majority of the Brazilian population has had sexual intercourse at some point in their lives (93.9%). Mean age of initiation was 17.3 years. Prevalence of consistent condom use was only 22.8%, being even lower among women (20.9%). Moreover, 59% of the population reported not having used a condom in the past 12 months, the main reason being trusting their partner (73.4%). The use of health services to obtain condoms was only 10.7%. It was observed that women, individuals with a higher age group, less education, and income had worse results in relation to the analyzed indicators, in addition to regional disparities.

CONCLUSION

Low prevalence of condom use was observed in the Brazilian population. In addition, important socioeconomic and demographic disparities were observed, pointing out the need to revisit, strengthen and expand public policies in the sexual and reproductive health field in order to prevent risky sexual behaviors and promote condom use, including double protection.

Changes in sexual behavior among high-school students over a 40-year period

The aim of this study was to investigate sexual behavior, contraceptive use, risk factors as well as sources of sex information among first-year high-school students in Sweden. Secondly, to assess differences between genders and study programs as well as changes over a 40-year period. A repeated cross-sectional survey was conducted in two cities. A questionnaire comprising 77 items was used. The study population consisted of 415 students (63.4% females). The median age of sexual intercourse was 15 years. In total, 37% had had sexual intercourse, compared to 56.3% in 2009 and 45% in 1999 (p < 0.001), and the proportion of students who had their first sexual intercourse was not influenced by gender. More students in vocational programs (46.3%), compared to theoretical (33.3%), had experience of at least one sexual intercourse (p = 0.019). The same extend of contraception use at first and latest intercourse was reported, compared to previous studies. Forty-nine percent were mostly informed about sex from the internet, while in previous years, magazines, family and youth clinics were the main information sources. Comparing over time, students were in general less sexually experienced and less engaged in non-penetrative sex and physical intimacy. These findings call for a new approach, when designing sex and relationship education and health-care counseling in adolescents.
