RESUMEN

BACKGROUND: Breast density (BD) is a strong risk factor for breast cancer. Little is known about how BD develops during puberty. Understanding BD trajectories during puberty and its determinants could be crucial for promoting preventive actions against breast cancer (BC) at early ages. The objective of this research is to characterize % fibroglandular volume (%FGV), absolute fibroglandular volume (AFGV), and breast volume (BV) at different breast Tanner stages until 4-year post menarche in a Latino cohort and to assess determinants of high %FGV and AFGV during puberty and in a fully mature breast. METHODS: This is a longitudinal follow-up of 509 girls from low-middle socioeconomic status of the Southeast area of Santiago, recruited at a mean age of 3.5 years. The inclusion criteria were singleton birth born, birthweight between 2500 and 4500 g with no medical or mental disorder. A trained dietitian measured weight and height since 3.5 years old and sexual maturation from 8 years old (breast Tanner stages and age at menarche onset). Using standardized methods, BD was measured using dual-energy X-ray absorptiometry (DXA) in various developmental periods (breast Tanner stage B1 until 4 years after menarche onset). RESULTS: In the 509 girls, we collected 1,442 breast DXA scans; the mean age at Tanner B4 was 11.3 years. %FGV increased across breast Tanner stages and peaked 250 days after menarche. AFGV and BV peaked 2 years after menarche onset. Girls in the highest quartiles of %FGV, AFGV, and BV at Tanner B4 and B5 before menarche onset had the highest values thereafter until 4 years after menarche onset. The most important determinants of %FGV and AFGV variability were BMI z-score (R2 = 44%) and time since menarche (R2 = 42%), respectively. CONCLUSION: We characterize the breast development during puberty, a critical window of susceptibility. Although the onset of menarche is a key milestone for breast development, we observed that girls in the highest quartiles of %FGV and AFGV tracked in that group afterwards. Following these participants in adulthood would be of interest to understand the changes in breast composition during this period and its potential link with BC risk.

RESUMEN

BACKGROUND: Mothers play a crucial role in influencing their daughters' HPV vaccination decisions. Addressing barriers to receiving HPV vaccination among mothers of girls may achieve two goals in one strike: increasing vaccination coverage among both mothers and their daughters. This study aims to examine the HPV vaccination uptake and its determinants among mothers of girls in China at both the individual and interpersonal levels. METHODS: From July to October 2023, a cross-sectional online study was conducted to investigate HPV vaccine refusal for daughters aged 9-17 years among 11,678 mothers in Shenzhen, China. A randomized selection method was employed, targeting 11 primary schools and 13 secondary schools in Shenzhen. The research team invited mothers of girls to participate in an anonymous online survey. Multilevel logistic regression models (level 1: schools; level 2: individual participants) were employed to analyze the data. RESULTS: Among 11,678 mothers, 41.1% self-reported receiving at least one dose of HPV vaccination. Through multilevel logistic regression analysis, eight items measuring illness representations of HPV, which refers to how people think about HPV, were associated with higher HPV vaccination uptake (AOR: 1.02-1.14). These items included identity (identifying symptoms of HPV), timeline (whether HPV is acute/chronic), negative consequences, personal and treatment control (whether HPV is under volitional control), concern, negative emotions, and coherence (overall understanding of HPV). In addition, participants refusing HPV vaccines for the index daughters (AOR: 0.82, 95%CI: 0.76, 0.89) had lower vaccine uptake. Perceived more difficulties in accessing the 9-valent vaccines (AOR: 1.06, 95%CI: 1.04, 1.08) and more satisfaction with vaccine-related promotional materials (AOR: 1.50, 95%CI: 1.46, 1.54) at the individual level were associated with higher vaccine uptake. At the interpersonal factors, higher frequency of exposure to testimonials given by others about HPV vaccination on social media (AOR: 1.19, 95%CI: 1.14, 1.25) and thoughtful consideration of the veracity of the information (AOR: 1.11, 95%CI: 1.07, 1.16) were correlated with higher HPV vaccination uptake. CONCLUSIONS: These findings offer essential implications for modifying HPV disease perceptions, addressing difficulties in accessing the 9-valent HPV vaccines, and enhancing health communication needs to improve HPV vaccine uptake among mothers of girls.

RESUMEN

BACKGROUND: Usual intakes of iodine in United States girls and women, including pregnant and lactating women have not been adequately studied. Adequate intake of iodine is critical for neurodevelopment of girls, thyroid functions, and reproductive health of women. OBJECTIVES: This study aimed to examine the adequacy and trends of iodine intake of United States girls and women between 2011 and 2020. METHODS: We mapped the sources of United States girls and women's iodine intake from the 29 food groups between 2011 and 2020 using United States Department of Agriculture's iodine data release 2. The total food intakes from 2 d of dietary recall of the United States National Health and Nutritional Examination Survey and estimated iodine concentrations of the food groups were used to calculate the usual iodine intakes of female participants. Trends of usual intakes, urinary iodine concentrations (UIC), and estimated intake adequacy were calculated. RESULTS: Median usual intakes of iodine estimated from diet and supplements and UIC of United States girls and nonpregnant, nonlactating women declined between 2011 and 2020 in all 3 age groups: ≤14 y, 15-49 y old, and ≥50 y. Median usual intakes of iodine for pregnant and lactating United States women declined as well. Inadequacy levels of usual iodine intake were 9.9% for nonpregnant, nonlactating women of reproductive age 15-49 y old, 40.3% for lactating, and 10.2% for pregnant women in the 2017-2020 period. Intake insufficiencies estimated from UIC were 48.8%, 63.2%, and 31.3% for nonpregnant, nonlactating women of reproductive age 15-49 y old, pregnant and lactating women, respectively, in the 2017-2020 period. A significant decline in milk consumption might be one of the major contributors to the dietary iodine decline in United States women. CONCLUSIONS: Iodine intake of United States girls and women were on the decline between 2011 and 2020 and the increased inadequacy of iodine intake deserves public health attention.

RESUMEN

Raising awareness and improving recognition, accurate classification, and enhanced access to new treatments represent current key challenges for carriers of haemophilia. Women and girls carrying genes for haemophilia often experience significant bleeding and/or low factor levels. The bleeding associated with female haemophilia is frequently overlooked, has a weak correlation with factor levels, and manifests differently than in males, with heavy menstrual bleeding being a predominant symptom. Recent changes in terminology now allow the diagnosis of haemophilia in females with low factor levels and differentiate between symptomatic and asymptomatic carriers of the gene. Observations from real-world experiences and limited clinical trial data have highlighted the positive impact of various new haemophilia treatments for women and girls with clotting factor deficiencies. There is an urgent need for initiatives that increase their access to these treatments and encourage well-designed clinical trials focusing on female-specific outcomes. In women with inherited bleeding disorders, early recognition and optimal management of heavy menstrual bleeding are crucial. However, treatment options and guidance from high-quality clinical trials are currently insufficient. Menstrual health assessment should be a regular part of monitoring women and girls with inherited bleeding disorders throughout their lives, emphasizing the importance of gathering data to improve future management.

RESUMEN

OBJECTIVES: Ovarian tumors in the pediatric population are rare. The incidence and frequency of subtypes differ between children and adults. Although not all tumors are aggressive, they may still lead to morbidity. The goal of this study was a comprehensive review of malignant ovarian tumors in children and adolescents diagnosed and registered in Sweden. METHODS: Individuals were identified through a search in the National Cancer Register, limited for ages 0-19, years 1970-2014. Stored tumor diagnostic material from regional biobanks was retrieved and reviewed. RESULTS: The study includes 345 individuals with ovarian tumors and 70.7% of them were between 15 and 19 years at time of diagnosis. No differences in incidence over time or geographic location were identified. The average follow-up time was 21.2 years and 5-year survival was 88.4%. Survival was similar in the different time periods, except for 1970-1979. Review was possible for 260 cases, resulting in 85 epithelial tumors, 121 GCTs, 47 SCSTs and 7 others. For age 0-4 years SCSTs dominated (85.7%), for 5-9- and 10-14-years GCTs dominated (70,8% and 75.0% respectively), and for age 15-19 years epithelial tumors dominated (43.8%). There was a strong agreement between review diagnosis and original diagnosis (Cohen's κ 0.944). Differentiating between entities within the sex cord-stromal group posed the biggest diagnostic challenge. CONCLUSIONS: Ovarian tumors in children and adolescents are rare and distinct from their adult counterparts regarding incidence and frequency. There was a strong concurrence between original and review diagnoses. The greatest diagnostic difficulty was subtyping of epithelial tumors and differentiating between tumors within the SCST group.

RESUMEN

BACKGROUND: Most adolescent girls fail to meet current physical activity guidelines. Physical activity behaviours track from childhood into adulthood and providing adolescent girls with opportunities to be physically active may have health benefits beyond childhood. The effects of walking interventions on adult cardiometabolic health are known, however less is understood about the potential of walking to promote physical activity in adolescents. Following the Walking In ScHools (WISH) feasibility study, this definitive trial aimed to evaluate the effectiveness of a novel, low-cost, school-based walking intervention at increasing physical activity levels of adolescent girls (aged 12-14 years). METHODS: Female pupils were recruited from eighteen schools across the border region of Ireland and in Northern Ireland. In intervention schools (n = 9), girls aged 15-18 years, were trained as walk leaders, and led the younger pupils in 10-15 min walks before school, at break and lunch recess. All walks took place in school grounds and pupils were encouraged to participate in as many walks as possible each week. The primary outcome measure was accelerometer determined total physical activity (counts per minutes, cpm). RESULTS: In total, 589 pupils were recruited to the study. At baseline, pupils engaged in a median (interquartile range (IQR)) 35.7 (21.2) mins moderate-vigorous physical activity (MVPA) per day and only 12% (n = 66) of participants met physical activity guidelines (60 min MVPA per day). The intervention was delivered for a mean (standard deviation (SD)) 19.9 ± 0.97 weeks. The mean post-intervention total physical activity for the intervention group was 676 cpm and 710 cpm in the control group. Post-intervention total physical activity did not statistically differ between groups when adjusted for age, body mass index z-scores and baseline physical activity (mean difference, -33.5, 95% CI = -21.2 to 88.1; p = 0.213). CONCLUSIONS: 'Scaling-up' physical activity interventions is challenging and despite a promising feasibility study, the results of this fully powered trial suggest that in this context, the WISH intervention did not increase device measured physical activity. Since the COVID-19 pandemic, school environments have changed and although pupils enjoyed the programme, attendance at walks was low, indicating that there is a need to better understand how to implement interventions within schools.

RESUMEN

Adolescent girls are an important target group for micronutrient interventions particularly in Sub-Saharan Africa where adolescent pregnancy and micronutrient deficiencies are common. When consumed in sufficient amounts and at levels appropriate for the population, fortified foods may be a useful strategy for this group, but little is known about their effectiveness and timing (regarding menarche), particularly in resource-poor environments. We evaluated the effect of consuming multiple micronutrient-fortified biscuits (MMB), sold in the Ghanaian market, 5 d/week for 26 weeks compared with unfortified biscuits (UB) on the micronutrient status of female adolescents. We also explored to what extent the intervention effect varied before or after menarche. Ten2Twenty-Ghana was a 26-week double-blind, randomised controlled trial among adolescent girls aged 10-17 years (n 621) in the Mion District, Ghana. Biomarkers of micronutrient status included concentrations of Hb, plasma ferritin (PF), soluble transferrin receptor (TfR) and retinol-binding protein (RBP), including body-iron stores. Intention-to-treat analysis was supplemented by protocol-specific analysis. We found no effect of the intervention on PF, TfR and RBP. MMB consumption did not affect anaemia and micronutrient deficiencies at the population level. MMB consumption increased the prevalence of vitamin A deficiency by 6·2 % (95 % CI (0·7, 11·6)) among pre-menarche girls when adjusted for baseline micronutrient status, age and height-for-age Z-score, but it decreased the prevalence of deficient/low vitamin A status by -9·6 % (95 % CI (-18·9, -0·3)) among post-menarche girls. Consuming MMB available in the market did not increase iron status in our study, but reduced the prevalence of deficient/low vitamin A status in post-menarcheal girls.

RESUMEN

The relationship between food insecurity and transactional sex is well recognized, but less is known about this relationship among adolescents. We analyzed cross-sectional baseline data from 3,130 female secondary students aged 12-19 enrolled in a three-arm, cluster randomized controlled trial to examine the association between food insecurity and transactional sex. The explanatory variable was food security and the outcome was ever engaging in transactional sex. Over one quarter (28.7%) reported any food insecurity and 1.9% of all participants (9.6% of sexually active participants) reported ever engaging in transactional sex. In adjusted models, ever experiencing any food insecurity was associated with a higher prevalence of ever transactional sex (PR: 1.60; 95% CI: 1.02, 2.49) compared to little to no food insecurity. These results provide insight into potential predictors of higher-risk sexual behavior in Rwanda; they also provide policy-makers with populations with whom to intervene on upstream determinants of transactional sex, notably poverty and food insecurity.

RESUMEN

Adolescent girls and young women (AGYW) in Eastern and Southern Africa face parallel epidemics of unintended pregnancy and HIV. Their sexual health decisions are often dominated by intersecting stigmas. In an implementation science project integrating delivery of daily, oral pre-exposure prophylaxis (PrEP) for HIV prevention into 14 post-abortion care (PAC) clinics in Kenya, we enrolled a subset of PrEP initiating AGYW (aged 15 to 30 years) into a research cohort. Utilizing log binomial models, we estimated the effect of PrEP stigma on PrEP continuation (measured via self-report and urine assay for tenofovir) and abortion stigma on contraceptive initiation. Between April 2022 and February 2023, 401 AGYW were enrolled after initiating PrEP through their PAC provider, of which 120 (29.9%) initiated highly-effective contraception. Overall, abortion and PrEP stigmas were high in this cohort. Abortion stigma was more prevalent among those that were adolescents, unmarried, and reported social harm. Among 114 AGYW returning for the month 1 follow-up visit, 83.5% reported continuing PrEP and 52.5% had tenofovir detected. In this subset, higher levels of PrEP stigma were significantly associated with greater likelihood of PrEP adherence, but not PrEP continuation. For abortion stigma, greater scores in the subdomain of isolation were significantly associated with greater likelihood of initiating a highly-effective contraception, while greater scores in the subdomain of community condemnation were significantly associated with reduced likelihood of initiating a highly-effective contraception. Given the burden of stigma documented by our work, PAC settings are a pivotal space to integrate stigma-informed counseling and to empower young women to optimize contraceptive and PrEP decisions.

RESUMEN

Adolescent girls and young women (AGYW) in South Africa are at a three times higher risk of acquiring HIV than their male counterparts. The HIV prevention cascade is a tool which can be used to measure coverage of HIV prevention services, although there is limited empirical evidence to demonstrate its application in low-resourced settings. The unifying framework is a conceptualisation of the HIV prevention cascade which theorises that both motivation and access are required for an individual to effectively use an HIV prevention method. We applied this framework to data from a random sample of 127,951 beneficiaries of a combination HIV prevention programme for AGYW aged 15-24 in South Africa to measure the steps to, and identify key barriers to, effective use of male condoms and oral pre-exposure prophylaxis (PrEP) among this vulnerable population. Barriers to each step were analysed using univariate and multivariable logistic regression. Among self-reported HIV-negative AGYW who had sex in the past 6 months, effective use of condoms (15.2%), access to PrEP (39.1%) and use of PrEP (3.8%) were low. AGYW were: less likely to be motivated to use condoms if they believed that they had a faithful partner (aOR 0.44, 95% CI 0.22-0.90) or disliked condoms (aOR 0.26, 95% CI 0.11-0.57), less likely to access condoms if the place where AGYW accessed them was far away (aOR 0.25, 95% CI 0.10-0.64), more likely to effectively use condoms if they received counselling on how to use them (aOR 2.24, 95% CI 1.05-4.76), less likely to be motivated to use PrEP if they did not believe PrEP was efficacious (aOR 0.35, 95% CI 0.17-0.72), more likely to be motivated if they felt confident that they could use PrEP, and more likely to have access to PrEP if they had ever been offered PrEP (aOR 2.94, 95% CI 1.19-7.22). This combination HIV prevention programme and similar programmes should focus on risk-reduction counselling interventions for AGYW and their male partners to improve effective use of condoms and ensure easy access to condoms and PrEP by making them available in youth-friendly spaces. Our findings demonstrate that the application of HIV prevention cascades can inform AGYW HIV prevention programming in low-resourced settings.

RESUMEN

Pre-exposure prophylaxis (PrEP) is highly effective at reducing HIV acquisition. We aimed to estimate usage of oral-PrEP, and factors associated with adherence among female sex workers (FSWs) in Nairobi, Kenya, using a novel point-of-care urine tenofovir lateral flow assay (LFA). The Maisha Fiti study randomly selected FSWs from Sex Worker Outreach Program clinics in Nairobi. Data were collected from 1003 FSWs from June-October 2019, including surveys on self-reported oral-PrEP adherence. Adherence was also measured using the LFA for HIV-negative FSWs currently taking oral-PrEP. Informed by a social-ecological theoretical framework, we used hierarchical multivariable logistic regression models to estimate associations between individual, interpersonal/community, and structural/institutional-level factors and either self-reported or LFA-assessed adherence. Overall, 746 HIV-negative FSWs aged 18-40 participated in the study, of whom 180 (24.1%) self-reported currently taking oral-PrEP. Of these, 56 (31.1%) were adherent to oral-PrEP as measured by LFA. In the multivariable analyses, associations with currently taking oral-PrEP included having completed secondary education, high alcohol/substance use, feeling empowered to use PrEP, current intimate partner, no recent intimate partner violence, having support from sex worker organisations, experiencing sex work-related stigma, and seeking healthcare services despite stigma. Associations with oral-PrEP LFA-measured adherence measured included having only primary education, experience of childhood emotional violence, belonging to a higher wealth tertile, and being nulliparous. Oral-PrEP adherence, measured by self-report or objectively, is low among FSWs in Nairobi. Programs to improve oral-PrEP usage among FSWs should work to mitigate social and structural barriers and involve collaboration between FSWs, healthcare providers and policymakers.

RESUMEN

The Tu'Washindi intervention addressed intimate partner violence (IPV) and relationship dynamics to increase PrEP use among adolescent girls and young women (AGYW) in Siaya County, Kenya. We evaluated feasibility and acceptability in a cluster-randomized trial in six DREAMS Safe Spaces. The multilevel intervention, delivered over 6 months, included three components delivered by DREAMS staff with support from the study team: an 8-session structured support club; community sensitization of male partners; and a couples PrEP education and health fair ("Buddy Day"). Feasibility and acceptability assessments included implementation process measures, questionnaires, and focus group discussions with AGYWs and post-intervention questionnaires with intervention providers. The study included 103 AGYWs aged 17 to 24 (N = 49 intervention), with 97% retention. Median age was 22, 54% were married, and 84% were mothers. At enrollment, 45% used PrEP and 61% reported lifetime IPV. All intervention participants attended at least one support club session (mean = 5.2 of 8) and 90% attended Buddy Day. At 6 months, most participants perceived Tu'Washindi to be effective: all agreed (with 54% reporting "strongly agree") that the intervention improved partner communication and 60% agreed they were better able to gain partner support for their PrEP use. Providers believed the intervention resonated with community values. Tu'Washindi was highly acceptable and feasible and it was perceived by AGYW participants and providers as being effective in improving partner relationships and supporting PrEP use.

RESUMEN

School attendance or completion is important for adolescents' development. Adolescents who drop out or are regularly absent from school are at higher risk of adverse sexual and reproductive health (SRH) outcomes. However, there is little evidence evaluating SRH service coverage among adolescents in and out of school. In the context of a large-scale combination HIV and pregnancy prevention intervention funded by the Global Fund, we compared the SRH intervention coverage and SRH risks among adolescent girls who dropped out of school with those who were still in school or who had completed grade 12 in South Africa. Among those still in school, we compared the SRH intervention coverage and SRH risk profiles of those with high versus low or no absenteeism. In 2017 to 2018, we conducted a household survey of adolescent girls aged 15 to 19 years in six of the ten combination intervention districts. Of 2515 participants, 7.6% had dropped out of school. Among the 1864 participants still in school, 10.8% had high absenteeism. Ever having had sex, and condomless sex were more prevalent among dropouts compared with non-dropouts. Dropouts were more likely to access SRH services such as condoms and contraceptives, except the combination prevention intervention services which were more likely to reach those who had not dropped out and were equally likely to reach those in school with high versus low/no absenteeism. Combination SRH prevention programmes can improve the accessibility of SRH services for adolescents in school/who complete school.

RESUMEN

Earlier pubertal onset has been associated with increased disordered eating symptoms in cisgender girls. Although this finding has been replicated across studies of disordered eating, most studies have focused on white samples. The lack of studies is surprising given that early pubertal timing may impact disordered eating risk in Black and Latinx girls differently due to trends of earlier pubertal onset in these groups and increased stressors related to interpersonal and structural racism and economic marginalization. Current methods of examining pubertal timing among Black and Latinx girls may also not fully capture their experience. Contextual factors (e.g., neighborhood and school racial/ethnic composition) may influence how minoritized girls both perceive and are affected by their pubertal timing. Moreover, factors such as ethnic-racial identity development and experiences of discrimination may be important mechanisms explaining the association between pubertal timing and disordered eating risk. This paper aims to provide a brief overview of studies examining pubertal timing and disordered eating risk among Black and Latinx girls in the US and to discuss recommendations for future research that integrate contextual factors in the examination of pubertal timing and its effects. PUBLIC SIGNIFICANCE: Early pubertal timing has been associated with increased risk of disordered eating symptoms among cisgender girls; however, studies have been limited due to the use of predominantly white samples. The article provides a brief overview of findings related to pubertal timing effects among Black and Latinx girls, discusses considerations for the measurement of pubertal timing, and highlights the need for inclusion of contextual factors in future research.

RESUMEN

BACKGROUND: The role of dietary intake on precocious puberty remains unclear. This study aimed to investigate the association between the amount and frequency of dietary intake and the risk of precocious puberty in Chinese girls. METHODS: In this case-control study, we enrolled 185 precocious puberty girls and 185 age-matched controls. Their dietary intake was assessed through a semi-quantitative food frequency questionnaire. Their sociodemographic and lifestyle data were collected. The associations between dietary intake and risk of precocious puberty were assessed by conditional logistic regression models. RESULTS: After multivariate adjustment, consuming a higher amount of red meat was associated with higher precocious puberty risk (OR = 2.74, 95% CI: 1.25-6.02), while a higher frequency of fruit ( P for trend = 0.024) and amount of vegetable intake was associated with a lower risk of precocious puberty (P for trend = 0.002). The high vegetable and protein dietary pattern was significantly negatively associated with precocious puberty (OR = 0.78, 95% CI: 0.63-0.97), whereas the high animal food and fruits dietary pattern was remarkably positively associated with precocious puberty (OR = 1.36, 95% CI: 1.09-1.69), after adjusting for age and body mass index. CONCLUSIONS: High vegetable and protein dietary pattern is a protective factor against precocious puberty, while high animal food and fruits dietary pattern is a risk factor for precocious puberty in Chinese girls. Attentions should be paid to a reasonable intake of red meat, eggs, and fruits in children's daily diet, increase their intake of vegetables, in order to reduce the risk of precocious puberty.

RESUMEN

BACKGROUND: In Ethiopia, premenstrual syndrome (PMS) was predominantly studied among university students who were in their early 20s; as a result, little is known about the prevalence of premenstrual syndrome among adolescent girls. Therefore, this study aimed to determine the prevalence of premenstrual syndrome and identify factors associated with premenstrual syndrome among secondary school female students in the Dessie city administration, 2023. METHODS: An institutional-based cross-sectional study was conducted involving a sample of 630 participants. A structured self-administered data collection tool was used to gather the necessary information. To ensure data quality, the pretesting and training of the data collectors and supervisors were conducted. The collected data were entered into Epi-data software and analyzed using SPSS version 25. Frequency tables, graphs, means, and medians were used to describe the characteristics of the study participants. Binary logistic regression was employed to identify significant factors. Variables with a p-value ≤ 0.05 with 95% confidence interval (CI) of adjusted odds ratio (AOR) in the final multivariable logistic regression were reported as statistically significant factors associated with PMS. Model fitness was evaluated using the Hosmer and Lemeshow goodness-of-fit test. RESULTS: In the present study, the prevalence of PMS was 22%, 95% CI = 19-26%. FACTORS: Age ≥ 18 years (AOR = 0.54; 95% CI: 0.34, 0.86), duration of menstruation ≥ 7 days (AOR = 3.61; 95% CI: 1.25, 10.37), presence of chronic illness (AOR = 2.08; 95% CI:1.04, 4.16), coffee intake (AOR = 6.05; 95% CI: 2.05, 17.87), alcohol intake (AOR = 0.49; 95% CI: 0.28, 0.86), use of pain medication (AOR = 2.06; 95% CI:1.10, 3.86), use of hormonal contraceptives (AOR = 3.9; 95% CI:1.58, 9.62), sleep disturbance (AOR = 3.82; 95% CI: 2.29, 6.42) and physical exercise (AOR = 0.50; 95% CI: 0.28, 0.87) were significantly associated with PMS. CONCLUSION: A significant number of students in this study were affected by premenstrual syndrome. Age, duration of menstruation, presence of chronic illness, coffee intake, use of pain medication, use of hormonal contraceptives, and sleep disturbance were significantly associated with PMS. Students should avoid excessive use of alcohol, coffee intake and use of pain medication without prescription.

RESUMEN

BACKGROUND: Despite being a normal occurrence, menstruation requires hygienic care and is associated with a number of myths and wrongdoings. Menstrual hygiene issues have been linked to major health issues, such as urinary tract and reproductive tract infections. Consequently, the purpose of this study was to evaluate the management of menstrual hygiene and related aspects among teenage students in Debre Markos town, North West, Ethiopia. METHODS: From March 15 to April 15, 2019, teenage pupils in Debre Markos town participated in a cross-sectional mixed study. An in-depth interview and a self-administered structured questionnaire were used to gather data. Quantitative information was imported into Epi Data and then exported to SPSS for examination. A 95% Confidence Interval of p-value ≤ 0.05 was used to declare significance. The method of thematic content analysis was used to examine the qualitative data. RESULT: This study comprised 531 individuals in total, with a 96.2% response rate. Approximately 260 adolescent females (49%, 95% CI: 39.2, 59.2) had good management practices for menstrual hygiene. Girls whose mothers were private employees (AOR: 0.3, 95% CI: 0.09, 0.99), self-employed (AOR: 0.52, 95% CI: 0.28, 0.98) and housewives (AOR: 0.53, 95% CI: 0.29, 0.98), and parent-adolescent discussions about menstruation (AOR: 1.62, 95% CI: 1.40, 3.34) were significantly associated with good menstrual hygiene management. Adolescence aged 17 years or older (AOR: 2.13, 95% CI: 1.32, 3.44) were found to have good knowledge regarding menstrual hygiene (AOR: 1.59, 95% CI: 1.43, 2.94). The qualitative study found that ignorance, an unfavorable school climate, and cultural and economic factors were the main causes of teenagers' poor menstrual hygiene. CONCLUSION: Nearly half of adolescent girls had good menstrual hygiene practice. Menstrual hygiene practice was associated with adolescent age, knowledge of menstruation, maternal occupational and discussion with parents. Girls had difficulty to manage menstrual hygiene due to poor knowledge, unsafe school environment, and cultural barriers. Thus, school-based programs aimed at improving knowledge towards menstrual hygiene management are needed.

RESUMEN

BACKGROUND: Zambian adolescent girls and young women (AGYW) have high HIV incidence and face barriers to the use of pre-exposure prophylaxis (PrEP). Parental support improves PrEP use and adherence in some settings, but negative parental attitudes toward HIV prevention may inhibit engagement with AGYW. We explored perceptions of future PrEP methods among AGYW and parents and parent-youth engagement on HIV prevention and PrEP use. METHODS: We conducted a qualitative descriptive study among AGYW and parents of AGYW in five provinces in Zambia in September-October 2021. We conducted 10 focus group discussions (FGDs) and four in-depth interviews (IDIs) with AGYW participants (n = 87) and seven FGDs and four IDIs among parents of AGYW (n = 62). All FGDs and IDIs were audio-recorded, transcribed verbatim, and analyzed to identify qualitative themes. RESULTS: Most AGYW participants preferred the discreet nature and longer duration of injectable PrEP compared to the PrEP ring and oral PrEP. Many AGYWs reported inability to disclose PrEP use to their parents due to lack of parental support based on cultural taboos against premarital sex. Nevertheless, AGYW participants said they would like to talk to their parents about PrEP so their parents could support their use. Many parents also described difficulties discussing PrEP with their daughters because of cultural and religious beliefs about abstinence from sex before marriage. However, parents acknowledged that the threat of HIV is real and said they need PrEP knowledge and guidance on speaking with their children about HIV prevention and PrEP. CONCLUSIONS: Although many parents are currently not playing a role in daughters' decisions about PrEP use, both parents and AGYW are willing to engage with each other on HIV prevention issues. To foster parent-child engagement, HIV prevention programs should not only provide information about PrEP but also address social norms that impede discussion of HIV prevention and equip both parents and AGYW with skills and support for such conversations. Community sensitization is also needed as new PrEP products are introduced, to create an enabling environment for parent-child engagement by increasing awareness, countering misconceptions, and reducing stigma.

RESUMEN

Through a national cross-sectional survey, the present study investigated the use and content of injury prevention training (IPT), and associated attitudes and beliefs, involving stakeholders in Danish girls' and women's elite football (U14, U16, U18, and Danish Women's League teams). A total of 168 stakeholders (coaches, physical performance coaches, physiotherapists, medical doctors, and club management) from 18 Danish elite clubs were invited to participate. Of these, 158 were eligible to participate, and 110 participants (69.6% response rate) provided 191 valid survey responses, as some provided more than one response due to multiple affiliations within the same club. The use of IPT ranged from 91.1% to 100% across team levels, with approximately 50% reporting up to 1-2 h/week. Interestingly, only 52.9%-72.7% of the responses indicated use of an evidence-based IPT program, with lowest adoption at the U14 and Danish Women's League teams. The FIFA 11+ was the most used evidence-based IPT program. The majority of the participants (>72%) had positive perceptions regarding IPT impact on injury reduction. These findings indicate that, while IPT is broadly used across Danish girls' and women's elite football teams, the implementation of evidence-based IPT programs varies, with lower adoption of these programs among the youngest and senior elite teams. Hence, there is a need to enhance integration of IPT programs proven effective in girls' and women's elite football. Notably, stakeholders expressed positive perceptions regarding the impact of IPT on injury reduction, which provides valuable support for future efforts to strengthen IPT in football practice.

RESUMEN

BACKGROUND: Following the Taliban's resurgence, Afghan girls were probited from attending school and university, likely causing adverse psychological effects. Therefore, the present study investigated depression, suicidal ideation, and quality of life (QoL) among Afghan girls banned from education by the Taliban. METHODS: A survey study assessed depression, suicidal ideation, and QoL among 426 females prohibited from attending secondary schools, high schools, and universities by the Taliban. The study used the CES-D 20 Scale to assess depression, and the WHOQOL-Bref Questionnaire to assess QoL. Associations between variables were tested with chi-square tests, and predictors of QoL were analyzed through multivariate regression analysis. RESULTS: Among the 426 participants, 87.6% exhibited depression symptoms and 49.8% reported suicidal thoughts. Significant predictors of overall QoL included monthly family income (B = 0.147, P = 0.001), recent others' behavior toward participants (B = -0.247, P < 0.001), physical illness (B = 0.110, P = 0.011), experiencing a recent traumatic event (B = 0.108, P = 0.015), depression (B = -0.159, P < 0.001) and suicidal ideation (B = -0.187, P < 0.001). CONCLUSIONS: In Taliban-ruled Afghanistan, the results indicated that female students who have been prohibited from studying in classes have a high prevalence of depression and suicidal ideation. Having depression and suicidal ideation significantly predicted decreased quality of life among female students.
