Since the release of the Supreme Court decision in June 2022, researchers have been working to better understand the impact that the growing number of abortion restrictions are having on the provision of and access to abortion services in the United States (US). Less is known about the impact of abortion restrictions on the provision of sexual and reproductive health (SRH) services more broadly, including at clinics that do not directly offer abortion. Between November 2023 and February 2024, we conducted interviews with SRH managers, clinic managers, and other administrators at publicly funded SRH clinics around the US to generate evidence on the effects of state-level abortion restrictions on the provision of abortion and related services, such as pregnancy options counselling and abortion referrals, at facilities providing contraceptive services.

The standard measure of unmet need for contraception is not person-centered and may not adequately represent women's contraceptive needs. To demonstrate the strength of a modified measure, we replicated the standard algorithm for unmet need, then created a person-centered algorithm that considers (1) whether nonusers want to use contraception and (2) whether users want to use a different method. We applied the standard and person-centered algorithms to a sample of 847 married Rohingya women aged 15-49 years living in camps in Cox's Bazar, Bangladesh, a population about whom little is known regarding contraceptive need.

The Programme of Action adopted after the International Conference on Population and Development (ICPD), and later the Beijing Declaration, affirmed commitments to the human right to decide on the number and spacing of one's children and have the information and means to do so. In this study, we estimate trends related to this component of reproductive agency-undesired births per thousand women who want to avoid pregnancy, the conditional undesired birth rate-with annual rates for five-year periods from 1975 to 2024. Worldwide, 36 million undesired births occurred annually in 2020-2024 compared to 45 million annually in 1990-1994, corresponding to a decrease in rate from 61 to 32.

Background: Bronchodilator responsiveness testing is mainly used for diagnosing asthma. We aimed to investigate whether it is associated with progression to chronic airflow obstruction over time.

Methods: The multinational Burden of Obstructive Lung Disease cohort study surveyed adults, aged 40 years and above, at baseline and followed them up after a mean of 9.

Background: Despite induced abortion being highly legally restricted in Pakistan, studies in 2002 and 2012 showed that many women rely on abortion when faced with an unintended pregnancy. Following the 2012 study, concerted efforts were made to improve contraceptive services and to strengthen postabortion care. The availability and use of misoprostol also expanded in the past decade.

Background: The assessment of small airways obstruction (SAO) using spirometry is practiced in population-based studies. However, it is not clear what are the most used parameters and cut-offs to define abnormal results.

Methods: We searched three databases (Medline, Web of Science, Google Scholar) for population-based studies, published by 1 May 2021, that used spirometry parameters to identify SAO and/or provided criteria for defining SAO.

Introduction: In recent years, there has been increasing interest in the use of spirometry for the assessment of small airways obstruction (SAO) driven by the idea that these changes occur prior to development of established obstructive lung disease. Maximal mid-expiratory and distal flow rates have been widely used despite a lack of agreement regarding parameter selection or definition of an abnormal result. We aim to provide evidence from population-based studies, describing the different parameters, definitions of normal range and the resulting impact on prevalence estimates for SAO.
