Hormonal contraceptives and asthma in women of reproductive age: analysis of data from serial national Scottish Health Surveys.

ABSTRACT: OBJECTIVES:Sex steroid hormones may explain known gender-related variations in asthma prevalence and clinical manifestation. We investigated the relationship between use of hormonal contraceptives and asthma in women, and assessed evidence of biological interaction between use of hormonal contraceptives and body mass index in this relationship. DESIGN:Population-based analysis using data from serial (i.e. 2003, 2008 and 2010) Scottish Health Surveys. SETTING:Random samples of the Scottish general population. PARTICIPANTS:A total of 3257 non-pregnant, 16-45-year-old women. EXPOSURE:Current use of hormonal contraceptives. MAIN OUTCOME MEASURES:Self-reported current physician-diagnosed asthma, current wheezing symptoms, wheezing attacks and treatment for asthma or wheeze. RESULTS:Women comprising 30.9% (95% confidence interval 29.3-32.5) were currently using any hormonal contraceptive and current physician-diagnosed asthma was present in 6.5% (95% confidence interval 5.7-7.4). Use of any hormonal contraceptive was associated with reduced risk of current physician-diagnosed asthma (odds ratio 0.68; 95% confidence interval 0.47-0.98) and receiving ?3 asthma care episodes (odds ratio 0.45; 95% confidence interval 0.25-0.82), but the evidence was equivocal for wheezing attacks. Use of hormonal contraceptives among overweight or obese women was non-statistically significantly associated with asthma, but there was 42-135% increased risk in overweight and obese non-contraceptive using women. CONCLUSIONS:Use of hormonal contraceptives may reduce asthma exacerbations and number of care episodes. Overweight and obese non-contraceptive-using women may be at increased risk of asthma. Prospective studies are now needed to confirm these findings. Both oestrogen and progesterone may stimulate smooth airway muscle function and inhibit the activities of TH2 responses. Future studies should investigate these underlying mechanisms.

Project description:BackgroundGlobally, hormonal contraceptives have proved to be effective in the prevention of unwanted pregnancies. However, despite evidence of the many benefits associated with the use of hormonal contraceptives, concerns related to their safety and side effects have been reported. We conducted a study to explore the perspectives on the side effects of hormonal contraceptives among women of reproductive age in Kitwe district of Zambia.MethodsAn explorative qualitative study was done among 32 women of reproductive age (18-45 years). Participants were selected conveniently as they accessed family planning services at a designated reproductive, maternal, and child health facility. Data collection was done through in-depth interviews (IDIs). Recruitment of participants and data collection continued until the saturation point was reached. The interviews were recorded, translated, and transcribed verbatim. Data were imported into NVivo.x64 for coding and node generation after which categories and themes were developed manually.ResultsOverall, participants demonstrated a considerable amount of knowledge of family planning, recounting the economic and health benefits as well as demerits of family planning use. The main reasons for discontinuing and switching hormonal contraceptive methods were the desire to get pregnant and the fear of unpleasant side effects, including excessive bleeding or prolonged menstruation, headache, dizziness, lower abdominal/back pain, and weight gain. Most importantly, participants cited concerns about the delay in the resumption of fertility after the termination of contraception and how the side effects disrupted their daily activities at home.ConclusionThere is a need for family planning providers to offer family planning services that address the side effects of hormonal contraceptives during counselling and how women can manage them. Family planning services should adopt a patient-centred approach that takes into consideration the concerns regarding side effects and how this affects the quality of life among women. Also, there is a need to extend family planning services to include scheduled follow-ups and clinical management of contraceptive side effects among women.

Project description:BackgroundThe Centers for Disease Control and Prevention's US Medical Eligibility Criteria for Contraceptive Use recommends that combined hormonal contraceptives (ie, birth control pills, contraceptive patch, vaginal ring) should be avoided in women with specific medical conditions because of the increased risk of cardiovascular events associated with estrogen use. Whether women with category 3 (theoretical or proven risk usually outweigh the advantages) or category 4 (unacceptable health risk) contraindications are appropriately avoiding estrogen-containing combined hormonal contraceptives is unknown.ObjectiveWe describe the prevalence of combined hormonal contraceptive use among a sample of reproductive-age women with medical contraindications to estrogen use. Our hypothesis was that women with categories 3 and 4 contraindications would use estrogen-containing contraception less often than women without medical contraindications. We also explored whether inappropriate estrogen-containing contraceptive use is related to contraceptive provider characteristics.Study designData are from the baseline survey of the MyNewOptions study, which included privately insured women residing in Pennsylvania aged 18-40 years, who were sexually active and not intending pregnancy in the next year. Women were surveyed about their medical conditions, contraceptive use, and characteristics of their contraceptive provider. Women were considered to have a contraindication to combined hormonal contraceptives if they reported a category 3 or category 4 contraindication: hypertension, smokers older than age 35 years, a history of venous thromboembolism, diabetes with complications, coronary artery disease, systemic lupus erythematosus with antiphospholipid antibodies, breast cancer, or migraine headaches with aura. χ(2) tests for general association were used to compare combined hormonal contraceptives use, contraceptive health provider characteristics, and sociodemographic data in women with and without contraindications to estrogen use.ResultsThe MyNewOptions baseline study sample included 987 adult women who were mostly young (46% were 18-25 years), white (94%), employed (70%), and married or cohabiting (54%). Thirteen percent (n = 130) of the sample had a medical contraindication to estrogen-containing contraceptive use: migraine with aura (81%) was the most common contraindication, followed by smokers older than age 35 years (7%), hypertension (11%), history of venous thromboembolism (4%), and diabetes with complications (2%). High use of combined hormonal contraceptives was reported among the women with medical contraindications to estrogen at 39% (n = 51). This was not statistically different from women without a medical contraindication (47%, P = .1). Among the 130 women with a contraindication, whether they did or did not use an estrogen-containing contraceptive did not vary by education level, income, or weight category. With respect to their contraceptive prescribers, there were no differences in prescriber specialty, provider type, or clinic type comparing women using and not using an estrogen-containing contraceptive.ConclusionAmong this study sample of reproductive-age women, there was a high rate of combined hormonal contraceptive use in women with a medical contraindication to estrogen use. These women may be at an increased risk for cardiovascular events. Processes need to be improved to ensure that women with medical contraindications to estrogen-containing contraception are being offered the safest and most effective methods, including long-acting reversible contraceptives, such as intrauterine devices and the contraceptive implant.

Project description:BackgroundInformation on the mortality rate and proportional cause-specific mortality is essential for identifying diseases of public health importance, design programmes, and formulating policies, but such data on women of reproductive age in Bangladesh is limited.MethodsWe analysed secondary data from the 2001, 2010, and 2016 rounds of the nationally representative Bangladesh Maternal Mortality and Health Care Survey (BMMS) to estimate mortality rates and causes of death among women aged 15-49 years. We collected information on causes of death three years prior to each survey using a country-adapted version of the World Health Organization (WHO) verbal autopsy (VA) questionnaire. Trained physicians independently reviewed the VA questionnaire and assigned a cause of death using the International Classification of Diseases (ICD) codes. The analysis included mortality rates and proportional mortality showing overall and age-specific causes of death.ResultsThe overall mortality rates for women aged 15-49 years decreased over time, from 190 per 100 000 years of observation in the 2001 BMMS, to 121 per 100 000 in the 2010 BMMS, to 116 per 100 000 in the 2016 BMMS. Age-specific mortality showed a similar downward pattern. The three diseases contributing the most to mortality were maternal causes (13-20%), circulatory system diseases (15-23%), and malignancy (14-24%). The relative position of these three diseases changed between the three surveys. From the 2001 BMMS to the 2010 BMMS and subsequently to the 2016 BMMS, the number of deaths from non-communicable diseases (e.g. cardiovascular diseases and malignancies) increased from 29% to 38% to 48%. Maternal causes led to the highest proportion of deaths among 20-34-year-olds in all three surveys (25-32%), while suicide was the number one cause of death for teenagers (19-22%). Circulatory system diseases and malignancy were the two leading causes of death for older women aged 35-49 years (40%-67%).ConclusionsThere was a gradual shift in the causes of death from communicable to non-communicable diseases among women of reproductive age in Bangladesh. Suicide as the primary cause of death among teenage girls demands urgent attention for prevention.

Project description:BackgroundUnintended pregnancy leads to unsafe abortion, which is one of the commonest causes of maternal deaths in developing countries including Ghana. Lots of unintended pregnancies can be avoided using emergency contraceptives (EC). Emergency contraceptives are mostly used after unprotected sexual intercourse and have a ninety-nine percent chance of preventing unintended pregnancy when taken correctly. However, unlike other modern contraceptives such as condoms, emergency contraceptives cannot prevent sexually transmitted infections.ObjectivesThis study aimed at assessing the factors influencing the use of emergency contraceptives among reproductive-age women in the Kwadaso Municipality, Ghana.MethodsA community-based descriptive cross-sectional study design was conducted in three sub-municipalities of the Kwadaso Municipality. A multistage sampling method was used to select 312 women in their reproductive age within households. A simple random sampling method was first used to select the sub-municipalities (Kwadaso Central, Asuoyeboah, and Agric-Nzema). Participants were selected from households through a systematic sampling procedure and responses were solicited from women who consented to participate in the study. The selection was strictly dependent on the number of eligible women in a household, that is, in an event where more than one woman was found in a household, a simple random sampling method was used to select only one woman from that household. STATA 15.0 was used to analyse the data. Binary logistic regression was used to find the adjusted estimates and associations between EC use and the exposure variables. P-values ≤ 0.05 were considered statistically significant at 95% Confidence Interval (CI).ResultsThe findings showed that 79.67% of the women had ever used EC. Amongst them, 59.83% used EC following unexpected unprotected sex, and 24.69% used EC following failed coitus interruptus. Women's attitude towards EC (AOR = 8.52, p<0.001), religion (AOR = 4.56, p = 0.004), and monthly income (AOR = 0.29, p = 0.030) were found to have significant influence on their use of EC.ConclusionThe level of EC use among the women was high. Women's attitude towards EC, religion, and monthly income were the major factors influencing the use of EC. Thus, strategies to promote EC use should emphasize on addressing the attitude of women towards EC through sex education in schools, various religious institutions, and the community at large with the services of health authorities and support from governmental and non-governmental organizations whose focus is to address the need for reproductive health services in order to reduce the misconception regarding the use of EC.

Project description:BackgroundDiscontinuation of contraceptives without any change in fertility intention is often associated with unintended pregnancy which ends up with induced abortion and unplanned birth. Despite the Ethiopian government's emphasis on the provision of long-acting contraceptive methods, little attention has been paid to the study of its discontinuation; particularly, no study has been reported in the study area. Thus, this study aimed to assess the discontinuation rate of long-acting reversible contraceptives and associated factors among reproductive-age women in Butajira town, Central Ethiopia, 2020.MethodsCommunity-based cross-sectional study was conducted from 1 April to 1 May 2020. A systematic random sampling method was used to select 227 women. Data were collected by a structured and pretested questionnaire. Epi-data (version 4.6.2) and Statistical Package for the Social Sciences (version 25) were used for data entry and analysis, respectively. A multivariable logistic regression model was used to predict the relation between dependent and independent variables. Finally, a significant statistical association was assured using an adjusted odds ratio at a 95% confidence interval and p value < 0.05.ResultsThis study revealed that the discontinuation rate of long-acting reversible contraceptives was 50 (22.5%; 95% confidence interval: 17.8-27.2). The main reason for discontinuation was facing side effects 26(52%); from these menstrual disruption 19 (73.1%) was the main reason. Time consumed to reach the health facility (adjusted odds ratio: 6.16, 95% confidence interval: 1.46-25.97), desire to have more children (adjusted odds ratio: 5.3, 95% confidence interval: 1.13-24.81), and counseled about the benefit of long-acting reversible contraceptives (adjusted odds ratio: 0.08, 95% confidence interval: 0.02-0.39) were predictors of discontinuation of long-acting reversible contraceptives.Conclusions and recommendationsThis study showed that the discontinuation rate was high when compared to Ethiopian Demographic Health Survey 2016. Routine pre-insertion counseling about the benefits and side effects of long-acting reversible contraceptives by healthcare providers is highly recommended. In addition, we recommend further trials using larger sample sizes on predictors of discontinuation of long-acting reversible contraceptives.
