UNASSIGNED: Induced abortion can seriously harm the physical and mental health of adolescent women. Long-acting reversible contraception (LARC) can effectively reduce unplanned pregnancies and prevent repeated abortions among adolescents. This study aimed to analyse the factors affecting the choice of LARC among adolescents in Chongqing of China.
UNASSIGNED: A total of 555 adolescents who underwent induced abortions for unplanned pregnancies between January 2019 and October 2021 were selected as study subjects. Logistic regression analysis was used to determine the factors affecting adolescent LARC choices following induced abortions.
UNASSIGNED: The factors that affected adolescent LARC choices included an average monthly income ≥ ¥3000 (OR = 3.432, 95% CI: 1.429∼8.244), history of previous abortions (OR = 3.141, 95% CI: 1.632∼6.045), worrying about unplanned pregnancy (OR = 0.365, 95% CI: 0.180∼0.740), parental support for using LARC (OR = 3.549, 95% CI: 1.607∼7.839), sexual partners\' support for using LARC (OR = 2.349, 95% CI: 1.068∼5.167), concerns about using LARC (OR = 0.362, 95% CI: 0.176∼0.745), and willingness to use free IUDs (OR = 13.582, 95% CI: 7.173∼25.717).
UNASSIGNED: Cost is one of the factors affecting LARC choices. Parents and sexual partners may play important role in the choice of LARC.
The study analysed the choice of contraceptive methods and the factors affecting the choice of long-acting reversible contraception methods after induced abortion among adolescents in Chongqing, China. The results showed that the income level, history of previous abortions, extent of worrying about unplanned pregnancy, parents’ and sexual partners’ attitude towards to use long-acting reversible contraception methods, concerns about using long-acting reversible contraception methods, and willingness to use free intrauterine devices were the factors affecting the choice of long-acting reversible contraception methods after induced abortion among adolescents.

This study aimed to determine whether condom use varied between adolescents and young women using long-acting reversible contraception (LARC) vs non-LARC hormonal methods and assess if the initiation of LARC was associated with lower condom use.
This study used data from a large longitudinal study of sexually active females aged 13-25 years. Questionnaires assessed contraception, condom use, sexual history, and partner characteristics at the baseline visit and every 6 months. Log-binomial regression analyses examined associations between hormonal contraceptive methods and condom use, and the moderating effects of age and number of sexual partners. Exploratory analyses compared condom use based on partner characteristics.
Of 1512 participants, 1116 reported LARC or non-LARC hormonal method use during any study visit. Among baseline and new LARC users, 75.7% and 84.7% reported intrauterine device (IUD) use, respectively. Condom use at baseline among hormonal non-LARC users (37.5%) was significantly higher (p < 0.01) than LARC users (23.5%). Condom use among LARC vs non-LARC users was moderated by age in that LARC was associated with lower condom use among participants aged 13-18 years, but not those aged 19-25 years. Number of sexual partners was not a significant moderator. Among participants with increased sexually transmitted infection (STI) risk based on partner characteristics, LARC users had lower condom use compared to non-LARC users.
Condom discontinuation was common following initiation of LARC and hormonal non-LARC methods. However, condom use was lower in LARC users at baseline, among younger adolescents, and if partners had risk factors for STIs.
Condom discontinuation following initiation of highly effective contraception increases the risk of STI. Young women using LARC may be at greater risk than non-LARC users given lower condom use despite having partners with risk factors for STIs. Condom use counseling for STI protection is critical for adolescents.

Some contraceptive methods, such as long-acting and permanent methods, are more effective than others in preventing conception and are key predictors of fertility in a community. This study aimed to determine which factors were linked to married women of childbearing age who no longer desired children using long-acting reversible contraceptives (LARCs) in Yemen. We used a population-based secondary dataset from Yemen\'s National Health and Demographic Survey (YNHDS), conducted in 2013. The study analyzed a weighted sample of 5149 currently married women aged 15 to 49 years who had no plans to have children. Logistic regression analyses were used to investigate the parameters linked to the present use of LARCs. The final model\'s specifications were evaluated using a goodness-of-fit test. An alpha threshold of 5% was used to determine statistical significance. Of the total sample, 45.3% (95% CI: 43.3-47.4) were using contraception. LARCs were used by 21.8% (95% CI: 19.6-24.1) of current contraceptive users, with the majority (63.8%) opting for short-acting reversible contraceptives (SARCs). In the adjusted analysis, maternal education, husbands\' fertility intention, place of residence, governorate, and wealth groups were all linked to the usage of LARCs. According to the findings, women whose spouses sought more children, for example, were more likely to use LARCs than those who shared their partners\' fertility intentions (AOR = 1.44; 95% CI: 1.07-1.94; P = .015). In this study, married women of reproductive age who had no intention of having children infrequently used contraception and long-acting methods. Improving women\'s education and socioeconomic status could contribute to increasing their use of LARCs.

Unintended pregnancy is a global issue with serious ramifications for women, their families, and society, including abortion, infertility, and maternal death. Although existing contraceptive strategies have been widely used in people\'s lives, there have not been satisfactory feedbacks due to low contraceptive efficacy and related side effects (e.g., decreased sexuality, menstrual cycle disorder, and even lifelong infertility). In recent years, biomaterials-based long-acting reversible contraception has received increasing attention from the viewpoint of fundamental research and practical applications mainly owing to improved delivery routes and controlled drug delivery. This review summarizes recent progress in advanced biomaterials for long-acting reversible contraception via various delivery routes, including subcutaneous implant, transdermal patch, oral administration, vaginal ring, intrauterine device, fallopian tube occlusion, vas deferens contraception, and Intravenous administration. In addition, biomaterials, especially nanomaterials, still need to be improved and prospects for the future in contraception are mentioned.

OBJECTIVE: To understand the associations between awareness, attitudes, and intentions to use long-acting reversible contraceptives (LARCs) among youth seeking induced abortion services in Shanghai, China.
METHODS: A cross-sectional survey was carried out among 1,215 nulliparous youth with unintented pregnancies in 41 hospitals of Shanghai, China, through a stratified sampling process between January and May 2019. Multivariable logistic regression was used to test the associations between awareness, attitudes and intentions to use LARCs.
RESULTS: Around 70% of youth had heard of at least one method of LARCs. About 38% of youth perceived that the copper-bearing intrauterine contraceptive device (Cu-IUD) was safe; the rate was 8% and 7%, respectively, for levonorgestrel-releasing intrauterine system (LNG-IUS) and subdermal implants. Less than 40% of youth thought Cu-IUD was effective in contraception, and it was around 6% for LNG-IUS and subdermal implants. Overall, less than 8% of youth expressed intentions to use LARCs. Positive attitudes towards LARCs were highly associated with the intentions to use LARCs [adjusted Odds Ratio (OR) 3.22, 95% confidence interval (CI) 1.96-5.42, p < 0.001].
CONCLUSIONS: Low awareness and negative attitudes towards LARCs were found in this study, and the negative attitudes towards LARCs could contribute to low intentions to use LARCs among youth who had already experienced unintended pregnancies.

The objective of this study was to evaluate the role of public-sector family planning program impact scores and other country-level factors on LARC use among young women aged 15 to 24.
We conducted this research using a large population database covering several decades\' worth of multi-wave cross-sectional samples of the demographic health survey (DHS) and the World Bank website data. We carried out a multi-level analysis on data from 1990 to 2019 from 22 Sub-Saharan African countries, with 163,242 participants.
We found LARC use was at 3.1% of all young women under study. Sierra Leone, 2019 survey had the highest LARC use at 21,961 per 100,000. A 10% increase in public-sector family planning program impact scores was positively associated with LARC use with odds ratio of 1.44, 95% CI, 1.43-1.45). We also noted that a 1% increase in HIV prevalence was associated with a reduced odds ratio of LARC use at 0.75 (95% CI, 0.70-0.81).
Findings from this study provide empirical evidence highlighting the importance of country-level factors in influencing LARC use among young women in sub-Saharan Africa IMPLICATIONS: For young women in Africa, policymakers need to increase their effort on national family planning programs especially in the public sector. Broader societal level interventions to improve LARC use are required. Specific interventions must address the complexities of HIV prevention and LARC use to benefit young women living in countries with a high HIV prevalence.

OBJECTIVE: To assess whether improving providers\' education by video training using a mobile phone could affect providers\' knowledge and attitude toward long-acting reversible contraceptives (LARCs), and thus further affect adolescents\' and young nulliparous women\'s decisions to use LARCs. DESIGN, SETTING, PARTICIPANTS, INTERVENTION, AND MAIN OUTCOME MEASURES: This prospective case-control study was performed between 2019 and 2020. A total of 40 healthcare providers participated, of which 20 received \"LARC First\" video training, whereas the other 20 served as the control group and received no training. Surveys were conducted of 244 adolescents and young women who were consulted by these 2 groups of healthcare providers before abortion surgery. The data were used to analyze the relationship between providers\' knowledge scores and the percentage of women who received counseling on LARCs decided to use LARCs, and what percentage continued to do so 12 months after surgery.
RESULTS: Providers from the study group scored higher in LARC knowledge than the control group. Compared to the control group, women in the study group reported receiving more counseling on LARCs (81.4% vs 7.9%) and more often chose to use LARCs (24.6% vs 2.4%). Twelve months later, there was no significant difference in contraceptive continuation between study and control groups, but study group participants were more likely to be using LARCs (P < .001).
CONCLUSIONS: Video training for providers improved both their knowledge and willingness to recommend LARCs and increased the probability of adolescent and young nulliparous women using these methods to reduce unintended pregnancy.

UNASSIGNED: Adenomyosis and endometriosis are common causes of pelvic pain in women of reproductive age. Furthermore, adenomyosis is a major cause of menorrhagia. This study aimed to evaluate the effects of Etonogestrel implants on pelvic pain and menstrual flow in women requiring long-acting reversible contraception and suffering from adenomyosis or endometriosis.One hundred women with adenomyosis or endometriosis and asking for contraception with Etonogestrel implants were enrolled in this study and were followed-up for 24 months. Patients were interviewed on pelvic pain by visual analog scale (VAS) pain score, menstrual flow by the number of sanitary napkins, menstrual bleeding pattern, weight gain, breast pain, and any other treatment side effects.Seventy four patients who were treated with Etonogestrel implants completed the 24-month follow-up in which we found a significant decrease in pelvic pain VAS scores comparing baseline scores to 6, 12, and 24 months (baseline: 6.39 ± 2.35 to 24-month: 0.17 ± 0.69, P < 0.05). The menstrual volume decreased significantly compared with that at baseline ((40.69 ± 30.92) %, P < 0.05). However, vaginal bleeding, amenorrhea, weight gain, and acne occurred after treatment in some patients.Etonogestrel implants were effective in reducing pelvic pain and menstrual flow of adenomyosis or endometriosis.

BACKGROUND: This study aimed to describe the intentions of and barriers to the use of long-acting reversible contraceptives (LARCs) in the post-abortion period among women seeking abortion in mainland China.
METHODS: A cross-sectional study was conducted from July 2015 to December 2015 using a waiting room questionnaire. A total of 381 women seeking abortions were recruited at a public hospital abortion clinic. The outcome variable was an \'intention-to-use\' LARCs in the immediate post-abortion period. Chi-square tests were used to assess associations between categorical variables. Statistically significant variables (p ≤ 0.05) were then further analyzed by logistic regression.
RESULTS: Among 381 respondents, 42.5% intended to use LARCs in the immediate post-abortion period; 35.2% intended to use intra-uterine devices (IUDs); and 13.9% intended to use implants. Previous use of LARC was a predictor for an intention to use LARCs (odds ratio [OR] = 2.41; 95% confidence interval [CI]: 1.06-5.47). Participants with one or no child had reduced odds for an intention to use LARC (OR = 0.32, 95% CI: 0.15-0.47 and OR = 0.29, 95% CI: 0.13-0.68, respectively). Women with a higher sex frequency (at least once per week) showed increased odds for LARC use (OR = 3.34; 95% CI: 1.03-10.78) and married women were more likely to use LARC than single women (OR = 1.57; 95% CI:1.00-2.47). Women who planned to have another baby within two years were more likely not to use LARCs in the immediate post-abortion period (OR = 0.97; 95% CI: 0.43-2.12). Barriers to the use of LARCs were anxiety relating to impaired future fertility (56.2%), LARCs being harmful to health (45.2%), irregular bleeding (44.3%), risk of IUD failure (41.6%) and lack of awareness with respect to LARCs (36.1%).
CONCLUSIONS: Intention to use LARCs was predicted by marital status, frequency of sexual activity, number of children, planned timing of next pregnancy, and previous LARC use. Impaired future fertility, being harmful to health, irregular bleeding, risk of complications, and lack of awareness with regards to LARCs were the main barriers in their potential use.

To evaluate the contraceptive status among Chinese women of reproductive age and factors associated with contraceptive methods.
A cross-sectional study from November 2015 to January 2016 was conducted. We used APP to collect demographics and contraceptive use information of women aged 14-44 years in China.
A total of 23,669 women completed the study. After data cleaning, 19,768 (83.5%) women were included in the final analysis. The prevalence of contraceptive use was 78.9%; while 21.05% of women did not use any method, condoms (40.10%), rhythm, or withdrawal (31.03%) were the most commonly used methods. When contraceptive methods were divided into four categories-long-acting contraceptives (LAC), short-acting contraceptive (SAC), Others, and \"No use\"-the prevalence was 6.1% (601/19,678), 40.8% (8022/19,678), 35.1% (6912/19,678), and 21.1% (4143/19,678), respectively. Women with a high level of education, being unmarried, and sexually active women tended to choose SAC; married women were associated with LAC usage. Women with irregular menstrual cycle used a high proportion of emergency contraception.
The prevalence of contraceptive use was 78.9%, with condom use being most prominent. Young women of reproductive age have low awareness of contraception. Relevant departments should take necessary measures to improve this situation.
