Is age of menarche directly related to vitamin D levels?

INTRODUCTION: Very few studies have examined the direct link between age of menarche and vitamin D level and controversial results have been reported. This study aimed to investigate the association between vitamin D and age of menarche in a group of adolescent girls in an area with plenty of sunshine. METHODS: At baseline, data were collected on 722 middle schoolgirls that were randomly selected by probability proportional to size sampling method. Of this group, 598 were followed including 173 who had their menarche during the follow-up. Serum 25-hydroxyvitamin D (25OHD) was measured at baseline using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Data on potential confounders were collected at baseline from the parents using self-administered questionnaire and from schoolgirls through face-to-face interview. Multiple linear regression and time-to-event analysis were used to investigate the association between 25OHD concentration and age of menarche. RESULTS: The mean (SD) age of the study group was 12.51 (0.91) years while the main (SD) age of menarche was 11.82 (1.04) years. The prevalence of vitamin D deficiency (<50 nmol/L) among schoolgirls was 91.69%. We found no evidence for the association between 25OHD levels and age of menarche before (ß, .00, 95% confidence interval (CI) [-0.01, 0.01]; p = .808) or after (ß, .00, 95% CI [-0.01, 0.01]; p = .765) adjusting for potential confounders. We also found no evidence for association between 25OHD status and age of menarche before (p = .424) or after (p = .356) adjusting for potential confounders. Time-to-event analysis showed no association between 25OHD level or status and age of menarche (p = .850). CONCLUSION: In Middle Eastern setting, where vitamin D deficiency is common despite plenty of sunshine, vitamin D is not a major determinant of the age at menarche. Regardless of the link between vitamin D and age of menarche, there are several other health benefits of having adequate vitamin D level during childhood and adolescence.

A systematic review of factors associated with uncontrolled diabetes and meta-analysis of its prevalence in Saudi Arabia since 2006.

The study aims to systematically review the literature for risk factors associated with poor glycaemic control among type 2 diabetes mellitus (T2DM) patients in Saudi Arabia (SA) and conducts a meta-analysis of its prevalence. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, we searched the Scopus, PubMed, PsycINFO, Web of Science, and CINAHL Plus databases from May to November 2018. The search terms were T2DM, glycaemic control, and SA. The inclusion criteria include the following: observational studies which were conducted in T2DM patients in SA reporting prevalence or/and personal, psychological or behavioural predictors in papers published after 2006. Articles were assessed using a modified Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) tool. Studies included in the meta-analysis defined uncontrolled T2DM as glycated haemoglobin ≥7% (53 mmol/mol), and reported results were based on a random-effects model. Eighteen of the following articles (3 retrospective cohort studies, 1 case-control study, and 14 cross-sectional studies) were included. The quality of the studies (high: 2; moderate: 7, and low: 9) varied. The pooled prevalence of uncontrolled T2DM in SA was 77.7% (95% CI, 71.2-84.2). In the included studies, the most consistent predictors of poor glycaemic control were longer diabetes duration, lack of self-efficacy, and low knowledge of diabetes. However, significant variations in research designs were observed across the studies. A national diabetes prevention and treatment program is needed to lessen the burden of diabetes in SA. Future studies should address the personal, psychological, and behavioural factors of poor glycaemic control in SA at national level.

Needlestick injury prevention training among health care workers in the Caribbean.

The rate of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections among health care workers that is caused by sharps injuries is higher in the Caribbean and Latin America than in other regions of the world. To respond to and reduce occupational exposures to bloodborne pathogens while also strengthening capacities in the Caribbean, needlestick injury prevention training programs for health care workers were implemented, beginning in 2011. The programs included lectures, workshops, policy reviews, evaluations of safety devices, and workplace assessment. During the training, baseline data from health care workers on their personal history of needlestick injuries and bloodborne pathogen exposure was collected. That baseline data showed that 40% of the participants had sustained sharps injuries during their professional career. In this capacity-building effort, 210 health care workers from five countries have been trained, six health care centers in the Caribbean have been evaluated. and occupational safety and health committees have been established in various countries to monitor and improve safety policies and practices.

La tasa de infecciones por los virus de la inmunodeficiencia humana (VIH), de la hepatitis B (VHB) y de la hepatitis C (VHC) en los trabajadores de atención de salud debidas a heridas por materiales punzocortantes es mayor en América Latina y el Caribe que en otras regiones del mundo. Con objeto de responder a las exposiciones laborales a los agentes patógenos de transmisión sanguínea y reducirlas, además de reforzar las capacidades en el Caribe, se instituyeron programas de capacitación para la prevención de las heridas por pinchazos accidentales en los trabajadores de salud a partir del 2011. Los programas comprendían conferencias, talleres, revisión de las políticas, análisis de los dispositivos de seguridad y evaluación de los lugares de trabajo. Durante la capacitación, se recopilaron datos iniciales suministrados por los trabajadores de atención de salud sobre sus antecedentes personales de heridas por pinchazos accidentales y exposición a agentes patógenos de transmisión sanguínea. Esos datos iniciales indicaron que 40% de los participantes habían sufrido alguna herida por materiales punzocortantes a lo largo de su carrera profesional. En esta iniciativa de formación de capacidades, se han capacitado 210 trabajadores de atención de salud de cinco países, se han evaluado seis centros de atención de salud en el Caribe y se han establecido comités de seguridad y salud ocupacional en diversos países para vigilar y mejorar las normas y prácticas de seguridad.

Minority stress model components and affective well-being in a sample of sexual orientation minority adults living with HIV/AIDS.

To date very little literature exists examining theoretically-based models applied to day-to-day positive and negative affective well-being among lesbian, gay, and bisexual (LGB) persons living with HIV/AIDS (PLWHA). Grounded in the perspective of Meyer, I. H. (2003). Prejudice, social stress, and mental health in lesbian, gay, and bisexual populations: Conceptual issues and research evidence. Psychological Bulletin, 129, 674-697. Minority Stress Model, the present study examined HIV- and sexual orientation-related factors influencing affective well-being (i.e., positive affect, negative affect, life satisfaction, and stress). Participants were 154 HIV-positive LGB adults from an urban area in the southwestern United States. Data were drawn from an archival database (i.e., Project Legacy). The study methodology featured a cross-sectional self-report survey of minority stress, victimization, coping, and emotional well-being, among other subjects. Primary regression results were: (1) males reported less general stress than females; (2) higher internalized HIV-related stigma was associated with elevated negative affect; (3) higher internalized homophobia was associated with elevations in negative affect and general stress; (4) higher coping self-efficacy was associated with lesser negative affect, lesser general stress, greater positive affect, and greater satisfaction with life; (5) a significant interaction between HIV-related victimization and coping self-efficacy showed that coping self-efficacy was positively associated with positive affect only (only for non-victims). Contrary to expectations, coping self-efficacy demonstrated the largest main effects on affective well-being. Results are discussed with regard to potential need for theoretical refinement of Minority Stress Model applied to PLWHA and affective well-being outcomes. Recommendations are offered for future research.

Health Profession Students' Interprofessional Socialization and Values Toward a College-Based Virtual Interprofessional Education Activity.

PURPOSE: The inclusion of interprofessional education (IPE) is essential for the health professions curricula and establishes the expectation of collaborative patient-centered care. The COVID-19 pandemic has required educators to develop innovative methods for IPE student engagement. The purpose of this study was to evaluate a college-based virtual IPE activity for first-year health profession students and measure their interprofessional socialization and values (ISVS) toward IPE teams. The validated interprofessional socialization and valuing scales (ISVS-9A/9B) were used. METHODS: A one-group pre-post-test design examined health profession students' ISVS from seven health programs before and after a virtual IPE activity. The IPE activity was a case-study grounded in the Interprofessional Education Collaborative (IPEC) core competencies that addressed each of the student learners' professional roles. RESULTS: A total of 244 students and 122 students completed the ISVS-9A/9B, respectively. A significant increase in the average total ISVS-9A/9B scores was observed among all student learners for 85 matched pairs (5.27 ± 1.11 vs 5.56 ± 1.02, p=0.01). Participating students generally found the activity valuable to their learning. CONCLUSIONS: The virtual composition of the IPE activity reduced logistical barriers and allowed for collaboration and awareness among students. Virtual IPE activities may be the cornerstone for interdisciplinary student engagement.

Vitamin D level in relation to depression symptoms during adolescence.

BACKGROUND: This study aimed to investigate the association between 25-hydroxyvitamin D (25(OH)D) and depression symptoms among adolescents in Kuwait, a country with a high prevalence of vitamin D deficiency. METHODS: A school based cross-sectional study was conducted on randomly selected 704 adolescents in middle schools. Data on depression symptoms were collected using the Children's Depression Inventory (CDI). Data on covariates were collected from the parents by self-administered questionnaire and from adolescents by face-to-face interview. Blood samples were analyzed in an accredited laboratory; and 25(OH)D was measured using liquid chromatography-tandem mass spectrometry. RESULTS: Of 704 adolescents, 94 (13.35%; 95%CI:10.35-17.06%) had depression symptom (a score of 19 or more on the CDI). There was no significant difference in the median CDI score between different vitamin D status (p = 0.366). There was also no significant correlation between serum 25(OH)D concentration and CDI score (Spearman's rank correlation = 0.01; p = 0.825).There was no significant association between 25(OH)D and depression symptoms whether 25(OH)D was fitted as a continuous variable (crude odds ratio (OR) 0 .99 [95%CI: 0.98, 1.01], p = 0.458 and adjusted OR 1.01 [95%CI: 0.99, 1.02], p = 0.233), categorical variable as per acceptable cut-of points (crude analysis p = 0.376 and adjusted analysis p = 0.736), or categorical variable as quartiles (crude analysis p = 0.760 and adjusted analysis p = 0.549). CONCLUSION: Vitamin D status does not seem to be associated with depression symptoms among adolescents in our setting. Nevertheless, it is important to have sufficient vitamin D levels during adolescence for several other health benefits.

Dental hygiene and public health students' perception of an online interprofessional education applied learning activity.

PURPOSE/OBJECTIVES: To pilot an online interprofessional education (IPE) applied learning activity (ALA), to understand students' socialization and values towards IPE teams, and evaluate the IPE learning activity for future implementation. METHODS: A pre-and post-test design was used to assess interprofessional socialization and values utilizing the (ISVS-9A/9B) surveys before and after the IPE ALA among dental hygiene (DH) and Master of Public Health (MPH) students (n = 86). Three statements from the ISVS-9A/9B surveys were not included due to the nature of the activity. The IPE ALA was a case study related to a federally funded community health center seeking funding for a dental van within 14 local targeted communities (i.e., children, senior citizens, special needs). Student groups were randomly assigned to one targeted community and completed questions that required application of prevention, systems thinking and management and solutions of oral health issues. Students collaboratively developed an executive summary and presentation through an online learning platform. RESULTS: A total of 73 DH (n = 38) and MPH (n = 35) students (84.8% response rate) completed the ISVS 9-A (modified), and 57 students DH (n = 33) and MPH (n = 24) students (66.3% response rate) completed the ISVS-9B (modified) and IPE activity evaluation. A positive change (pre-post) was observed based on the students' responses (p < 0.05) and 64% agreed that the skills obtained from the IPE ALA would help them in their careers. CONCLUSIONS: Overall, student learners' ISVS toward IPE improved after engaging in the online ALA. The use of online platforms is one low resource strategy to integrate IPE experiences into allied health and dental education.

Factors associated with tobacco smoking among Saudi college students: A systematic review.

INTRODUCTION: There has been an increase in tobacco smoking among Saudi college students in recent years. However, no study has examined, with a systematic approach, the extent to which specific factors are associated with tobacco smoking among this population. METHODS: PubMed, ProQuest, CINAHL, and Web of Science were utilized to retrieve studies addressing risk factors associated with tobacco smoking among Saudi college students between 2010 and 2019. After confirming their eligibility criteria, studies were imported to the NVivo software for data collection and synthesis. All included articles were critically appraised, based on a modified STROBE. RESULTS: Twenty-one out of 300 studies met the eligibility requirements for inclusion. Riyadh was the location, health-related science was the field of study, and male the gender of the population of most of the included studies. Only one study used a longitudinal design based on a theoretical framework, the rest were cross-sectional and lacked theoretical utilization. Four individual and two social factors were established to have a significant relationship with tobacco smoking behavior among college students in four or more studies. Environmental factors were found to be associated with a change in smoking behavior among Saudi college students based on two studies. CONCLUSIONS: There is a dearth of research in utilizing theoretical frameworks to guide the research in order to propose an intervention program among Saudi college students. Future research should aim to recruit participants from different institutions in the Kingdom of Saudi Arabia (KSA), apply other methodological approaches, test other measurements of tobacco smoking, and utilize a theoretical framework.

Smoking tobacco prevalence among college students in the Kingdom of Saudi Arabia: Systematic review and meta-analysis.

INTRODUCTION: During the last two decades, several studies have been published regarding the prevalence of tobacco smoking among college students in the Kingdom of Saudi Arabia (KSA). This systematic review and meta-analysis is intended to determine and examine the smoking prevalence in Saudi college students from 2010-2018. METHODS: PubMed, Science Direct, APA PsycNET, Web of Science, and CINAHL were used to search for published articles reporting the smoking prevalence among Saudi college students. After eliminating irrelevant articles, investigators independently assessed the quality of each article, based on Russell & Gregory guidelines. MetaXL software was used to calculate the pooled prevalence among included studies, using the IVhert model. Heterogeneity among the included studies was evaluated, using I2 statistic. Sensitivity analyses were conducted between male and female genders. RESULTS: Of the 295 published articles, 29 articles used a cross-sectional design to determine smoking prevalence among Saudi college students. Most of the studies were conducted in Riyadh at health-science-related colleges; the rest were performed in different cities and colleges. The meta-analysis showed that the pooled estimate of smoking prevalence among college students in the KSA was 17% (95% CI: 11-23%). Saudi male students had a prevalence rate of 26% (95% CI: 24-29%), whereas for Saudi female students the prevalence was 5% (95% CI: 3-7%). CONCLUSIONS: Smoking among Saudi college students was higher than in the majority of regional countries (e.g. Iran). Saudi male students had a higher smoking prevalence than Saudi female college students. Additionally, studies that reported a high prevalence targeted students in specific disciplines. Public health authorities in the KSA should develop a surveillance system that monitors the prevalence of tobacco smoking on campuses. A surveillance system of monitoring tobacco use among Saudi college students could be beneficial in determining the degree of the tobacco problem and in improving current tobacco control programs.
