Untangling the literature on obesity and contraception
Given the growing number of reproductive-age women who are obese, the impact that weight might have on contraceptive efficacy is important for reproductive providers caring for patients, and for public health as well as for personal health in general. Generally, there are few appropriately designed studies for any contraceptive method that explore the relationship between contraceptive efficacy and obesity. Although it does appear that obesity adversely affects contraceptive steroid hormone pharmacokinetics (e.g. drug levels and how drugs are metabolized), the literature has been conflicting regarding the impact on effectiveness. In this monthly update, we peek between the covers of Contraceptive Technology to learn the latest perspective on obesity’s impact on hormonal contraceptive effectiveness.
Over 1,000 smartphone applications are currently available to help people track their menstrual cycles. Most are not appropriate for pregnancy prevention, although the millions of people who have downloaded them do not necessarily understand this. Thus, providers should be prepared to guide their patients in identifying and selecting which apps provide accurate information and are appropriate for their particular needs, advise Contraceptive Technology authors Victoria Jennings and Chelsea Polis. Some apps facilitate use of an existing FABM (such as a symptothermal method, the Billings Ovulation Method, or the Standard Days method) by providing a digital platform that serves as an alternative to traditional paper and pencil charts or other tools used to track fertility signs. Another category of smartphone apps requires input of information about fertility signs but uses a predictive algorithm embedded within the app itself to determine the fertile time.
Medical conditions commonly worsen during the luteal phase and menses. This may reflect the complex and often poorly understood interplay of hormones with other physiologic processes throughout the body. Seizures, asthma, mental health disorders, and migraines are among the conditions more commonly exacerbated during a woman’s menstrual cycle. Anita Nelson and Lee Shulman offer guidance on interrupting the cycling interplay of hormones and exacerbation of medical conditions in their chapter on the Menstrual Cycle in the new edition of Contraceptive Technology. A classic example is menstrual migraines.
