Background: Although natural rubber latex remains dominant as the primary manufacturing material for male condoms synthetic materials first introduced in the early 1990s address many of the limitations of latex including the risk of allergies. Polyurethane elastomers allow condoms to be made significantly thinner to provide greater sensitivity and encourage greater use of condoms for contraception and STI prophylaxis. The primary objective of this Study was to evaluate the breakage, slippage and acceptability of two ultra-thin polyurethane condoms against a thin control latex male condom, designated latex C, in a randomized, cross over, masked, non-inferiority study. The condom designated Polyurethane A was designed for markets where 52/53 mm wide latex condoms are preferred whereas the condom designated Polyurethane B was designed for markets where the smaller 49 mm wide latex condom is preferred.
Methods: The Study was designed to meet the requirements specified in ISO 29943-1: 2017 and FDA guidelines for clinical studies on synthetic condoms. It was conducted by two Essential Access Health centres, one in Northern California and the other in Southern California. Sexually active heterosexual couples (300) aged between 18 and 45 years were recruited to use three sets of five condoms in a block randomized order, recording breakage, slippage and acceptability after each use. A total of 252 couples contributed 2405 evaluable condom uses per protocol for the Condom A versus Latex C comparison (1193 Polyurethane A plus 1212 Latex C), and 247 couples provided 2335 evaluable condom uses per protocol for the Condom B versus Latex C comparison (1142 Polyurethane B plus 1193 Latex C). Only condoms used for vaginal intercourse were included in the analysis.
Findings: Although the total failure rates (breakage and slippage) for the polyurethane condoms were higher than for the control Latex C condom, all condoms performed extremely well with low failure rates compared to similar condom studies. Condom Polyurethane A met the noninferiority requirements specified in ISO 23409:2011 relative to Latex C, the control NR latex condom, in the full Study population. While condom Polyurethane B did not meet the noninferiority requirement for the full Study population, it did meet the noninferiority requirement when analysis was restricted to the intended population (men with penis lengths ≤ 170 mm). Trial registration The Study is registered with ClinicalTrials.gov, NCT04622306, Protocol Reference SAGCS 2, initial release date 11/02/2020.
背景:尽管天然乳胶仍是制造男用安全套的主要材料,但 20 世纪 90 年代初首次推出的合成材料解决了乳胶的许多局限性,包括过敏风险。聚氨酯弹性体使安全套的厚度大大减薄,从而提高了灵敏度,并鼓励更多的人使用安全套避孕和预防性传播感染。本研究的主要目的是在一项随机、交叉、掩蔽、非劣效性研究中,评估两种超薄聚氨酯避孕套与一种名为乳胶 C 的超薄男用乳胶避孕套的破损率、滑动性和可接受性。聚氨酯 A 安全套专为 52/53 毫米宽的乳胶安全套市场而设计,而聚氨酯 B 安全套专为 49 毫米宽的较小乳胶安全套市场而设计:该研究的设计符合 ISO 29943-1:2017 和美国食品和药物管理局(FDA)关于合成安全套临床研究的指导方针中规定的要求。研究由两家基本保健中心进行,一家位于北加州,另一家位于南加州。研究人员招募了年龄在 18 至 45 岁之间的性活跃异性伴侣(300 对),让他们按照整群随机顺序使用三套共五只安全套,并记录每次使用后的破损、滑脱和可接受性。在安全套 A 与乳胶 C 的对比中,共有 252 对夫妇提供了每个方案 2405 次可评估的安全套使用次数(1193 次聚氨酯 A 加 1212 次乳胶 C);在安全套 B 与乳胶 C 的对比中,共有 247 对夫妇提供了每个方案 2335 次可评估的安全套使用次数(1142 次聚氨酯 B 加 1193 次乳胶 C)。只有用于阴道性交的安全套才被纳入分析:尽管聚氨酯安全套的总故障率(破裂和滑脱)高于对照组乳胶 C 安全套,但与同类安全套研究相比,所有安全套的故障率都很低,表现非常出色。与对照组乳胶 C(NR 乳胶安全套)相比,聚氨酯安全套 A 在全部研究人群中均达到了 ISO 23409:2011 中规定的非劣效性要求。虽然聚氨酯避孕套 B 在整个研究人群中不符合非劣效性要求,但在仅限于目标人群(阴茎长度小于 170 毫米的男性)进行分析时,它确实符合非劣效性要求。试验注册 该研究已在 ClinicalTrials.gov 注册,注册号为 NCT04622306,协议编号为 SAGCS 2,初始发布日期为 2020 年 2 月 11 日。

Background: Previous studies indicated that excessive engagement in digital devices could lead to negative psychological impacts in general population. We aimed to determine the association of electronic screen exposure with depression among women in early pregnancy.
Methods: A cross-sectional study was conducted from June 2021 to June 2022. A total of 665 women in early pregnancy were recruited and the information included socio-demographic characteristics, screen exposure and Patient Health Questionnaire - 9 depression scale.
Results: Among the women in early pregnancy, the total daily smartphone viewing time was the longest (median [P25-P75], 5 [3-6] hours/day) in the three types of electronic screen exposure. The total daily smartphone viewing time (P = 0.015, OR[95%CI] = 1.09[1.11-1.18]), smartphone (P = 0.016, OR[95%CI] = 1.24[1.04-1.47]) and television viewing time (P = 0.006, OR[95%CI] = 1.35[1.09-1.67]) before nocturnal sleep were significantly associated with depression among women in early pregnancy. The thresholds calculated by receiver operator characteristic curves were 7.5 h/day, 1.5 h/day and 1.5 h/day, respectively. In addition, women with higher scores of smartphone addiction were more susceptible to depression (P<0.001, OR[95%CI] = 1.11[1.07-1.16]). The top three smartphone usages in women with depression were watching videos (22.0%), listening to music (20.9%) and playing games (16.7%).
Conclusions: In conclusion, electronic screen exposure, including screen viewing time, smartphone addiction and problematic smartphone use was associated with depression among women in early pregnancy. Further studies are warranted to verify the conclusions.

Background: Improving maternal healthcare services is crucial to achieving the Sustainable Development Goal (SDG-3), which aims to reduce maternal mortality and morbidity. There is a consensus among different researchers that proper utilization of maternal healthcare services can improve the reproductive health of women, and this can be achieved by providing Antenatal Care (ANC) during pregnancy, Health Facility Delivery (HFD), and Postnatal Care (PNC) to all pregnant women. The main aim of this study was to investigate the utilization and factors associated with maternal and child healthcare services among women of reproductive age in the pastoralist communities in Kenya.
Methods: A cross-sectional survey was conducted among 180 pastoralist women who gave birth in the past two years across ten mobile villages in Marsabit County between 2nd January and 29th February 2019. Three key outcomes were analyzed, whether they attended ANC 4+ visits, delivered at HF, and received PNC. Pearson χ2 test and multivariate logistic regression analysis were conducted by IBM SPSS27.0 following Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. The significance level was set at p < 0.05.
Results: Of the 180 eligible pastoralist women (mean age 27.44 ± 5.13 years), 92.2% were illiterate, 93.9% were married, 33.3% were in polygamy, and 14.4% had mobile phones. The median commuting distance was 15.00 (10-74) km, 41.7% attended ANC 4+, 33.3% HFD, and 42.8% PNC. Those women residing close (≤ 15 km) to a health facility had a threefold higher ANC 4+ (OR 3.10, 95% CI 1.47-6.53), 2.8-fold higher HFD (OR 2.80, 95% CI 1.34-5.84), and 2.5-fold higher PNC (OR 2.49, 95% CI 1.19-5.22) probability. The likelihood was 30-fold higher for ANC 4+ (OR 29.88, 95% CI 6.68-133.62), 2.5-fold higher for HFD (OR 2.56, 95% CI 0.99-6.63), and 60-fold higher for PNC (OR 60.46, 95% CI 10.43-350.55) in women with mobile phones. A monogamous marriage meant a fivefold higher ANC 4+ (OR 5.17, 95% CI 1.88-14.23), 1.6-fold higher HFD (OR 1.67, 95% CI 0.77-3.62), and a sevenfold higher PNC (OR 7.05, 95% CI 2.35-21.19) likelihood. Hosmer Lemeshow test indicated a good-fitting model for ANC 4+, HFD, and PNC (p = 0.790, p = 0.441, p = 0.937, respectively).
Conclusion: In conclusion, the utilization of three essential maternal health services is low. Geographic proximity, monogamous marriage, and possession of mobile phones were significant predictors. Therefore, it is recommended that stakeholders take the initiative to bring this service closer to the pastoralist community by providing mobile health outreach and health education.
背景:改善孕产妇保健服务对于实现旨在降低孕产妇死亡率和发病率的可持续发展目标(SDG-3)至关重要。不同研究人员已达成共识,即适当利用孕产妇保健服务可改善妇女的生殖健康,而这可通过向所有孕妇提供孕期产前护理(ANC)、医疗机构接生(HFD)和产后护理(PNC)来实现。本研究的主要目的是调查肯尼亚牧区育龄妇女对母婴保健服务的利用情况及其相关因素:方法:2019 年 1 月 2 日至 2 月 29 日,在马萨比特县的 10 个流动村庄对过去两年分娩的 180 名牧民妇女进行了横断面调查。调查分析了三项主要结果,即她们是否参加了 ANC 4+ 次访视、是否在 HF 分娩以及是否接受了 PNC。根据加强流行病学观察性研究报告(STROBE)指南,采用 IBM SPSS27.0 进行了皮尔逊χ2 检验和多元逻辑回归分析。显著性水平设定为 p 结果:在 180 名符合条件的牧民妇女(平均年龄为 27.44 ± 5.13 岁)中,92.2% 为文盲,93.9% 已婚,33.3% 为一夫多妻制,14.4% 有手机。通勤距离的中位数为 15.00(10-74)千米,41.7% 的人参加过 4 次以上的产前保健,33.3% 的人参加过高频产前保健,42.8% 的人参加过孕前保健。那些居住在医疗机构附近(≤ 15 公里)的妇女,其产前检查 4+ 的概率高出三倍(OR 3.10,95% CI 1.47-6.53),高频产前检查的概率高出 2.8 倍(OR 2.80,95% CI 1.34-5.84),产前护理的概率高出 2.5 倍(OR 2.49,95% CI 1.19-5.22)。使用手机的女性获得 ANC 4+ 的概率高出 30 倍(OR 29.88,95% CI 6.68-133.62),获得 HFD 的概率高出 2.5 倍(OR 2.56,95% CI 0.99-6.63),获得 PNC 的概率高出 60 倍(OR 60.46,95% CI 10.43-350.55)。一夫一妻制婚姻意味着 ANC 4+ 的可能性高出 5 倍(OR 5.17,95% CI 1.88-14.23),HFD 高出 1.6 倍(OR 1.67,95% CI 0.77-3.62),PNC 高出 7 倍(OR 7.05,95% CI 2.35-21.19)。Hosmer Lemeshow 检验表明,ANC 4+、HFD 和 PNC 的拟合模型良好(分别为 p = 0.790、p = 0.441、p = 0.937):总之,三种基本孕产妇保健服务的利用率较低。地理位置远近、一夫一妻制婚姻和拥有手机是重要的预测因素。因此,建议利益相关者采取主动行动,通过提供流动医疗外展和健康教育,使这项服务更贴近牧民社区。

With a keen awareness of the size and health needs of the global adolescent population, governments, nongovernment organizations and the technical and funding agencies that support them continue to seek innovative answers to persistent programming challenges to increasing contraceptive use among sexually active adolescents. Adolescents 360 (A360) is a project implemented by Population Services International (PSI) and partners with funding from the Bill and Melinda Gates Foundation (BMGF) and the Children's Investment Fund Foundation (CIFF). The first phase of the project was implemented from 2016 - 2020 in Ethiopia, Nigeria, and Tanzania. A360 hypothesized that human centered design (HCD) could catalyze new insights into identifying and solving problems that limit adolescents' use of contraception. Despite initial promising results, A360 demonstrated very limited impact on modern contraceptive uptake among adolescents. The authors of this commentary were members of a technical advisory group to A360 and are uniquely positioned to provide insights on this project to complement those of A360's staff and evaluators, which are already in the public arena. Our analysis suggests that all stakeholders should take steps to rebalance their programs and investments to not only seek new solutions (i.e. game changers), but to also invest in the institutionalization of the solutions that have been generated over the past 40 years, prioritizing those that have shown evidence of effectiveness (i.e. adolescent responsive health service delivery) and those that demonstrate significant promise (i.e. social norm change).

Background: Family planning (FP) is crucial for reducing maternal and infant mortality and morbidity, particularly through the prevention of unsafe abortions resulting from unwanted pregnancies. Despite Cameroon's commitment to increasing the adoption of modern FP strategies, rural and poor populations still exhibit low demand due to limited access to healthcare services. This study documents the approach in developing family planning messages for the BornFyne prenatal management system as a platform to improve family planning awareness and enhance uptake.
Method: This is a mixed-methods study that employed the Health Belief Model (HBM). The study included a cross-sectional survey and focus group discussions in four districts of Cameroon. The survey explored household perspectives of FP and the use of mobile phone. Focus group discussions involved women, men, and community health workers to gain in-depth insights. Thematic analysis using themes from the HBM guided the analysis, focusing on perceived benefits, barriers, and cues to action.
Results: The survey included 3,288 responses. Thematic analysis of focus group discussions highlighted knowledge gaps and areas requiring additional information. Identified gaps informed the development of targeted FP messages aligned with BornFyne objectives and the Health Belief Model. Results revealed that most respondents recognized the benefits of FP but faced knowledge barriers related to side effects, cultural influences, and communication challenges between partners. Focus group discussions further highlighted the need for education targeting both men and women, dispelling misconceptions, and addressing adolescent and youths' ignorance. The study emphasized the importance of tailored messaging for specific demographic groups and culture.
Conclusion: Developing effective FP intervention messages requires a nuanced understanding of community perspectives. The BornFyne-PNMS family planning feature, informed by the Health Belief Model, addresses knowledge gaps by delivering educational messages in local dialects via mobile phones. The study's findings underscore the importance of community-based approaches to contextualizing and developing FP content targeting specific populations to generate tailored messages to promote awareness, acceptance, and informed decision-making. The contextualized and validated messages are uploaded into the BornFyne-family planning feature.

Infertility refers to the inability to conceive after 12 months of regular, unprotected sexual intercourse. Psychosocial aspects of infertility research are predominant in developed countries. A scoping review of psychosocial aspects of infertility research conducted in Africa between 2000 and 2022 was conducted. Twelve databases and grey literature were searched for articles. Studies were included if they were published in English and included findings from patients diagnosed with primary or secondary infertility. A total of 2 372 articles were initially found and screening resulted in 116 articles being included in the scoping review. Most of the studies (81%) were conducted in Nigeria, Ghana and South Africa. Psychosocial aspects explored included quality of life, barriers to treatment, attitudes and stigma, and sociocultural and religious aspects of infertility, among others. The review maps published psychosocial research in the context of infertility in Africa and identifies gaps for future research.

Introduction: Suburban population is increasingly growing in Iran. People in the suburbs usually have limited sexual information and there are limited studies into their sexual issues. This study aims the effect of sexual education (SE) based on the Sexual Health Model (SHM) on sexual functioning among women living in the suburbs.
Methods: This is a randomized controlled trial with two parallel groups. Seventy-six women will be selected through simple random sampling from healthcare centers in suburban areas and will be allocated to a control group (n = 38) and an intervention group (n = 38) with a randomization ratio of 1:1. Participants in the intervention group will receive SHM-based SE in three120 min weekly sessions which will be held using the lecture, question-and-answer, group discussion, and educational booklet methods. Data will be collected through a demographic and midwifery characteristics questionnaire, the Female Sexual Function Index, the Depression Anxiety Stress Scale, and the Sexual Quality of Life-Female, and will be analyzed through the analysis of covariance as well as the independent-sample t, the paired-sample t, and the Chi-square tests.
Discussion: We hope this study provides a clear framework for decision-makers and healthcare providers to provide appropriate policies and interventions for SE and thereby improve the sexual health of women in the suburbs.
Trial registration: This study was registered in the Iranian Registry of Clinical Trials on 2024.03.05 (code: IRCT20231121060133N1).
引言伊朗郊区人口日益增多。郊区居民通常获得的性信息有限,对其性问题的研究也很有限。本研究旨在探讨基于性健康模式(SHM)的性教育(SE)对郊区妇女性功能的影响:这是一项随机对照试验,分为两个平行小组。将从郊区的医疗保健中心通过简单随机抽样选取 76 名妇女,按 1:1 的随机比例分配到对照组(n = 38)和干预组(n = 38)。干预组的参与者将在每周三次、每次 120 分钟的课程中接受基于 SHM 的 SE,课程将采用讲座、问答、小组讨论和教育手册等方法进行。数据将通过人口统计学和助产士特征问卷、女性性功能指数、抑郁焦虑压力量表和女性性生活质量量表收集,并通过协方差分析、独立样本 t 检验、配对样本 t 检验和卡方检验进行分析:我们希望这项研究能为决策者和医疗服务提供者提供一个清晰的框架,为 SE 提供适当的政策和干预措施,从而改善郊区妇女的性健康:本研究于 2024.03.05 在伊朗临床试验注册中心注册(代码:IRCT20231121060133N1)。

Background: Physical, affective and behavioural symptoms associated with the menstrual cycle are commonplace. Adolescents with problematic symptoms have reported a negative impact on school attendance, behaviour and participation in physical activity. In the United Kingdom, evidence suggests that menstrual health education delivered by teachers focusses on menstrual cycle biology as opposed to management of menstruation and menstrual cycle related symptoms. Through obtaining the pupil voice, this study aimed to understand young people's perceptions and experiences of menstrual education in schools and their experiences of menstruating whilst at school, including within Physical Education.
Methods: To address the aims, a qualitative descriptive study was conducted. Nine focus groups with female pupils (n = 48; ages 10-15 years) were completed across six school locations in England and Wales, including primary and secondary schools. A range of elements relating to the menstrual cycle, education at school and PE were discussed by pupils.
Results: Four main themes were developed (a) Education preferences, (b) Period positive environments, (c) Personal experiences and (d) Impact on school. Similarities were reflected across focus groups in terms of current (lacking) education, lesson style and preferences, comfort of conversations, lack of school support and impact on school and PE.
Conclusion: The findings highlight the lack of menstrual education received and subsequent impact of menstruation and menstrual-related symptoms in school and PE. The abundance of information requested by pupils highlights the deficit in understanding about how to manage periods in school and remain engaged in physical activity. Schools can utilise information from the current study to; create period positive environments; consider lesson content and format; and explore how to support girls to stay physically active in PE.

Background: Social problems related to infertility are associated with a significant psychological burden for the involved couple. Previous studies have shown the positive effects of couple interactions on the psychological health of these couples; however, the specific conditions of participating in assisted reproductive treatments (ART) might influence the effect of couple collaboration. Therefore, the present study aimed to evaluate the relationship between couple collaboration, well-being during infertility, and the psychological indicators of infertile couples undergoing fertility treatment.
Methods: This cross-sectional study was conducted on 200 ART volunteer couples. Couple collaboration and well-being during infertility were evaluated using a validated researcher-made questionnaire, and the level of depression, anxiety, and stress was evaluated using the DASS-21 questionnaire in both couples. Statistical analysis was performed using the plug-in application PROCESS macro for SPSS and AMOS software.
Results: The results showed that couple collaboration was correlated with the level of depression, anxiety, and stress. Moreover, depression, anxiety, and stress levels were correlated with well-being during infertility. The direct and indirect effect of couple collaboration on the depression level was significant; however, the direct effect of couple collaboration on the level of anxiety and stress was not significant, and the effect of couple collaboration on these indicators was mediated by well-being during infertility. The fit index of the equation modelling showed a good fit of the relationship path between the variables of couple collaboration, well-being during infertility, and psychological indicators (CMIN = 4.196, p = 0.260).
Conclusion: The results of this study show that the specific conditions of participating in ART may affect the direct effects of couple interaction on an infertile couple's levels of anxiety and stress. These results suggest that in order to develop mental health programs for infertile couples, strategies based on couple collaboration that are associated with higher well-being during infertility should be developed and presented.
背景:与不孕不育有关的社会问题给相关夫妇带来了巨大的心理负担。以往的研究表明,夫妻互动对这些夫妻的心理健康有积极影响;然而,参与辅助生殖治疗(ART)的具体条件可能会影响夫妻合作的效果。因此,本研究旨在评估夫妻协作、不孕不育期间的幸福感以及接受生育治疗的不孕不育夫妇的心理指标之间的关系:这项横断面研究的对象是 200 对自愿接受 ART 治疗的夫妇。方法:这项横断面研究的对象是 200 对接受 ART 治疗的不孕不育志愿夫妇,使用研究人员自制的有效问卷对夫妇合作和不孕不育期间的幸福感进行了评估,并使用 DASS-21 问卷对夫妇双方的抑郁、焦虑和压力水平进行了评估。统计分析使用 SPSS 和 AMOS 软件的插件应用程序 PROCESS 宏进行:结果表明,夫妻协作与抑郁、焦虑和压力水平相关。此外,抑郁、焦虑和压力水平与不孕不育期间的幸福感相关。夫妻协作对抑郁水平的直接和间接影响显著;然而,夫妻协作对焦虑和压力水平的直接影响不显著,夫妻协作对这些指标的影响是以不孕不育期间的幸福感为中介的。方程建模的拟合指数显示,夫妻协作、不孕不育期间的幸福感和心理指标这三个变量之间的关系路径拟合良好(CMIN = 4.196,P = 0.260):本研究结果表明,参与 ART 的具体条件可能会影响夫妇互动对不孕夫妇焦虑和压力水平的直接影响。这些结果表明,在为不孕不育夫妇制定心理健康计划时,应制定并介绍基于夫妇合作的、与不孕不育期间较高幸福感相关的策略。
