Real-world experience of women using extended-cycle vs monthly-cycle combined oral contraception in the United States: the National Health and Wellness Survey.

BACKGROUND: The real-world experience of women receiving extended-cycle combined oral contraception (COC) versus monthly-cycle COC has not been reported. METHODS: Data were from the United States 2013 National Health and Wellness Survey. Eligible women (18-50 years old, premenopausal, without hysterectomy) currently using extended-cycle COC (3 months between periods) were compared with women using monthly-cycle COC. Treatment satisfaction (1 "extremely dissatisfied" to 7 "extremely satisfied"), adherence (8-item Morisky Medication Adherence Scale©), menstrual cycle-related symptoms, health-related quality of life (HRQOL) and health state utilities (Medical Outcomes Short Form Survey-36v2®), depression (9-item Patient Health Questionnaire), sleep difficulties, Work Productivity and Activity Impairment-General Health, and healthcare resource use were assessed using one-way analyses of variance, chi-square tests, and generalized linear models (adjusted for covariates). RESULTS: Participants included 260 (6.7%) women using extended-cycle and 3616 (93.3%) using monthly-cycle COC. Women using extended-cycle COC reported significantly higher treatment satisfaction (P = 0.001) and adherence (P = 0.04) and reduced heavy menstrual bleeding (P = 0.029). A non-significant tendency toward reduced menstrual pain (39.5% versus 47.3%) and menstrual cycle-related symptoms (40.0% versus 48.7%) was found in women using extended-cycle versus monthly-cycle COC. Significantly more women using extended-cycle COC reported health-related diagnoses, indicating preferential prescription for extended-cycle COC among women reporting more health problems. Consistent with this poorer health, more women using extended-cycle COC reported fatigue, headache, and activity impairment (P values < 0.05). There were no other significant differences between groups. CONCLUSIONS: This real-world observational study supports extended-cycle COC as a valuable treatment option with high satisfaction, high adherence, and reduced heavy menstrual bleeding.

Cycle control with an extended-regimen oral contraceptive combining levonorgestrel and ethinyl estradiol that includes continuous low-dose ethinyl estradiol instead of the traditional hormone-free interval.

PURPOSE: To evaluate scheduled and unscheduled bleeding and spotting over 1 year of treatment with 91-day extended-regimen combined oral contraception (COC) providing continuous low-dose ethinyl estradiol (EE) in place of the traditional 7-day hormone-free interval (HFI). PATIENTS AND METHODS: This post hoc analysis of a multicenter, open-label, 1-year, Phase 3 study of extended-regimen COC with 30 µg EE/150 µg levonorgestrel (LNG) for 84 days and EE 10 µg for 7 days included 799 sexually active, adult women who completed at least one 91-day cycle of therapy. Subjects recorded bleeding and spotting episodes daily using electronic diaries. Logistic regression analyses are reported as ORs with 95% CIs. RESULTS: There was a 10% increase (OR =1.102; 95% CI: 1.006-1.206) in the likelihood of reporting no scheduled bleeding for each additional 91-day cycle completed. From the third 91-day cycle, more than one fifth of women reported no scheduled bleeding (third cycle =23% [121/533]; fourth cycle =22% [97/446]). Among women who reported no scheduled bleeding at Cycle 1 (136/758 [18%]), ≥45% showed sustained lack of scheduled bleeding in later cycles. There were increases of 53% (OR =1.531; 95% CI: 1.393-1.683) and 31% (OR =1.307; 95% CI: 1.205-1.418) in the likelihood of reporting 0 to ≤6 days vs >6 days of unscheduled bleeding and spotting, respectively, for each additional 91-day cycle. By Cycle 2, more than 80% of women reported no unscheduled bleeding or ≤6 days of unscheduled bleeding during each 91-day cycle. CONCLUSION: Improved cycle control with decreased bleeding over time was shown during extended-regimen COC with 30 µg EE/150 µg LNG for 84 days and continuous low-dose EE instead of the traditional 7-day HFI. Women considering this regimen should be informed that those who complete at least one 91-day COC cycle will likely experience less bleeding/spotting in future cycles.

Development and conceptual validation of a questionnaire to help contraceptive choice: CHLOE (Contraception: HeLping for wOmen's choicE).

OBJECTIVE: The aim of this research was to develop a questionnaire to facilitate choice of the most appropriate contraceptive method for individual women. METHODS: A literature review was conducted to identify key aspects influencing contraceptive choice and inform development of a questionnaire for online completion. Questionnaire development was overseen by a steering committee consisting of eight gynaecologists from across Europe. The initial draft underwent conceptual validation through cognitive debriefing interviews with six native English-speaking women. A qualitative content analysis was conducted to accurately identify potential issues and areas for questionnaire improvement. A revised version of the questionnaire then underwent face-to-face and online evaluation by 115 international gynaecologists/obstetricians with expertise in contraception, prior to development of a final version. RESULTS: The final conceptually validated Contraception: HeLping for wOmen's choicE (CHLOE) questionnaire takes ≤10 min to complete and includes three sections to elicit general information about the individual, the health conditions that might influence contraceptive choice, and the woman's needs and preferences that might influence contraceptive choice. The questionnaire captures the core aspects of personalisation, efficacy and safety, identified as key attributes influencing contraceptive choice, and consists of 24 closed-ended questions for online completion prior to a health care provider (HCP) consultation. The HCP receives a summary of the responses. CONCLUSION: The CHLOE questionnaire has been developed to help women choose the contraception that best suits their needs and situation while optimising the HCP's time.

Coronary heart disease and HRT in France: MISSION study prospective phase results.

OBJECTIVE: To determine the morbidity incidence associated with Hormone Replacement Therapy (HRTs) in postmenopausal women. This paper presents the results concerning the incidence of coronary heart disease (CHD). DESIGN: MISSION study started on 5 January 2004, the cutoff for data collection was June 2006 (follow-up no. 1). 'Exposed group': postmenopausal women currently on HRT, commonly prescribed in France or stopped < or =5 years previously. 'Unexposed group': never received HRT or stopped >5 years previously. RESULTS: Data were available for 4949 patients (without CHD at the beginning of the follow-up): 2693 Exposed group and 2256 Unexposed group. The incidence during follow-up no. 1 of postmenopausal CHD was not significantly different in the Exposed group (0.11%) compared with the Unexposed group (0.13%). In the Exposed group the time between start of HRT and menopause was 2.93 +/- 4.46 years in those who experienced CHD and 1.53 +/- 3.20 years in those who had no incidence of CHD (p = 0.3). CONCLUSION: In the MISSION cohort, no increased risk of CHD was found in the Exposed group compared with the Unexposed group.

Breast cancer incidence and hormone replacement therapy: results from the MISSION study, prospective phase.

BACKGROUND: The MISSION Study (Menopause: Risk of Breast Cancer, Morbidity and Prevalence) is a historical-prospective study with random patient selection to determine breast cancer incidence in postmenopausal women with or without hormone replacement therapy (HRT). The first prospective follow-up phase started on 5 January 2004 and the cut-off date for data collection was 30 June 2006. PARTICIPANTS: Patients were divided into two groups: an 'exposed group' of women on HRT regimens commonly prescribed in France or who had stopped < or =5 years previously; and an 'unexposed group' of women who had never received HRT or stopped >5 years previously. In total 6755 patients were included; and prospective data were available for 4949 patients: 2693 in the exposed group and 2256 in the unexposed group. Women in the exposed group were younger, less overweight, and had fewer first-degree family histories of breast cancer than women of the unexposed group. Mean duration of HRT exposure was 8.3 years, with 31% being exposed for > or =10 years. RESULTS: The incidence of new breast cancer cases was 0.64% in the exposed group and 0.70% in the unexposed group (relative risk RR(exposed/unexposed) = 0.914, 95% confidence interval = 0.449-1.858; not modified when adjusted for age). Mean age at breast cancer diagnosis was similar in both groups. Breast cancer incidence in the exposed group was not significantly affected by the route of estradiol administration (cutaneous 0.69%; oral 0.52%) or HRT type (estradiol alone 0.28%; estradiol + progesterone 0.40%; estradiol + synthetic progestin 0.94%). CONCLUSION: No evidence was found for an increased risk of breast cancer in women exposed to HRT compared with non-exposed women.
