RESUMEN
PURPOSE: Several epidemiological studies have linked lead (Pb) exposure to induced oxidative stress and the promotion of inflammatory response. We performed a within-subjects study (repeated measures study) to evaluate the relationship between the concentration of blood lead (B-Pb) and toenail lead (T-Pb) and circulating markers of inflammation. METHODS: We evaluated the associations between B-Pb concentrations and T-Pb concentrations and circulating markers of inflammation, soluble intracellular adhesion molecule-1 (s-ICAM-1), soluble vascular adhesion molecule-1 (s-VCAM-1), and high-sensitivity C-reactive protein (hs-CRP) on 158 traffic enforcers from the Metropolitan Manila Development Authority (MMDA) traffic enforcer's health study. Linear mixed-effects models with random subject-specific intercepts were fitted to estimate the association between B-Pb and T-Pb exposure and circulating markers of inflammation, adjusting for confounding factors. RESULTS: Traffic enforcers were middle-aged men (89.4%) with a mean age (± SD) of 37.1 years ± 8.9 years and had a total of 293 valid markers of inflammation measurements. B-Pb concentration was related to increased hs-CRP levels. A 10% increase in B-Pb was associated with a 5.7% increase in hs-CRP level [95% confidence interval (95% CI): 1.3-10.1]. However, B-Pb was not associated with s-ICAM-1 and s-VCAM-1. Furthermore, no associations were observed between T-Pb and all the circulating markers of inflammation. CONCLUSIONS: Low-level B-Pb may increase hs-CRP among traffic enforcers. Moreover, the study suggests that Pb via the oxidative and inflammation pathways may have an essential role in the development of cardiovascular disease. Furthermore, MMDA and the Department of Labor and Employment can use our study's findings as evidence to conduct routine screening of blood heavy metals, especially Pb, among MMDA and other traffic enforcers as part of their yearly medical examination.

OBJECTIVES: We aimed to describe the gender-affirming hormonal therapy (GAHT) intake behaviour and regimen and the factors associated with the use of hormones inconsistent with reference GAHT regimen among transgender people in the Philippines. DESIGN: Cross-sectional study. SETTING: Transgender community clinic in Metro Manila, Philippines from March 2017 to December 2019. PARTICIPANTS: Gender-affirming care-seeking individuals of at least 18 years old, who self-identified as transgender or non-binary, and who self-reported current or previous use of GAHT at baseline consult. PRIMARY OUTCOME MEASURES: Reported drugs and/or administration routes not congruent with the World Professional Association for Transgender Health Standard of Care eighth edition were classified as hormone use outside the reference regimen. RESULTS: 253 transgender people reported current or previous intake of GAHT. Many trans women and transfeminine people (TWTFP; 58.9%, 86/146) reported using oral contraceptive pills (OCPs), whereas most trans men (TM; 73.8%, 79/107) reported injecting testosterone esters. Furthermore, 59.7% (151/253) used hormones outside the reference regimen, widely using OCP and anabolic steroids among TWTFP and TM, respectively. TWTFP (crude prevalence ratio, PR, 3.52; 95% CI 2.35 to 5.49) and those who take unprescribed GAHT (crude PR 2.37; 95% CI 1.08 to 6.68) were more likely to use hormones outside the reference regimen than TM and taking healthcare provider-prescribed GAHT, respectively. On adjusting for covariates, the prevalence of using hormones outside the reference regimen was approximately three times higher (adjusted PR 3.22; 95% CI 2.09 to 5.12) among TWTFP than TM. CONCLUSION: Trans people act on their high unmet gender-affirming care needs by taking unprescribed GAHT, many outside the reference regimen. Structural changes in the health system are warranted, including strengthened community-based self-administration practices.

BACKGROUND: The Dengvaxia® (dengue vaccine) controversy has been identified as one of the main reasons for the measles vaccine hesitancy in the Philippines. Our study aimed to identify various issues related to the Dengvaxia® controversy and to link these issues with the social perspective of measles vaccine refusal. METHODS: Semi-structured interviews and a focus group discussion using ethnography research were conducted with 41 parents and healthcare workers in Pasay City. Using Victor Turner's Social Drama Theory, our study identified existing social issues relating to the different angles of the Dengvaxia® controversy and the measles vaccine hesitancy. RESULTS: Misinformation on the failed Dengvaxia® rollout implementation has challenged the fundamental understanding of the importance of immunization programs. Our findings on vaccine hesitancy in the community showed a complex problem with compounded factors, including medical populism, moral panics and other social views. We described how Pasay City's clinic waiting room became a significantly important scenario where individuals often discuss information, concerns and experiences on vaccines and vaccine hesitancy. CONCLUSION: Our study suggests that the Dengvaxia® controversy may reduce the measles vaccination confidence in the Philippines. Lack of transparency played a crucial role in this dilemma, producing a cascading effect on the other vaccines' safety.

INTRODUCTION: The rampant distribution of idealised images on the internet may lead the general public to improve their body appearance in a way that is sometimes excessive, compulsive or detrimental to other aspects of their lives. There is a decreasing appreciation of body image among emerging adults and an increasing trend on skin-lightening practices linked with psychological distress. This protocol describes the mixed-method approach to assess the relationships among body image perception, skin-lightening practices and mental well-being of Filipino emerging adults and determine the factors that influence them. METHODS AND ANALYSIS: An explanatory sequential mixed-method approach will be used. A cross-sectional study design will involve an online self-administered questionnaire of 1258 participants, while a case study design will involve in-depth interviews with 25 participants. Data analysis will use generalised linear models and structural equation modelling with a Bayesian network for the quantitative data. Moreover, the qualitative data will use an inductive approach in thematic analysis. A contiguous narrative approach will integrate the quantitative and qualitative data. ETHICS AND DISSEMINATION: The University of the Philippines Manila Review Ethics Board has approved this protocol (UPMREB 2022-0407-01). The study results will be disseminated through peer-reviewed articles and conference presentations.

OBJECTIVE: The study aimed to demonstrate the feasibility of an unassisted and community-based HIV self-testing (HIVST) distribution model and to evaluate its acceptability among men-having-sex-with-men (MSM) and transgender women (TGW). METHODS: Our demonstration study focused on implementing the HIVST distribution model in Metro Manila, Philippines. Convenience sampling was done with the following inclusion criteria: MSM or TGW, at least 18 years old, and had no previous HIV diagnosis. Individuals taking HIV pre-exposure prophylaxis, on antiretroviral therapy, or female sex at birth were excluded. The implementation of the study was done online using a virtual assistant and a delivery system via courier due to COVID-19-related lockdowns. Feasibility was measured by the number of HIVST kits successfully delivered and utilized and the HIV point prevalence. Moreover, acceptability was evaluated by a 10-item system usability scale (SUS). HIV prevalence was estimated with linkage to care prioritized for reactive participants. RESULTS: Out of 1,690 kits distributed, only 953 (56.4%) participants reported their results. Overall, HIV point prevalence was 9.8%, with 56 (60.2%) reactive participants linked to further testing. Furthermore, 261 (27.4%) of respondents self-reported, and 35 (13.4%) of the reactive participants were first-time testers. The HIVST service had an overall median and interquartile range (IQR) SUS score of 82.5 (IQR: 75.0, 90.0), rendering the HIVST kits very acceptable. CONCLUSIONS: Our study suggests the acceptability and feasibility of HIVST among the MSM and TGW in Metro Manila, Philippines, regardless of their age or HIV testing experience. In addition, other platforms of information dissemination and service delivery of HIVST should be explored, including access to online instructional videos and printed materials, which may facilitate easier use and interpretation of results. Furthermore, due to our study's limited number of TGW respondents, a more targeted implementation strategy to reach the TGW population is warranted to increase their access and uptake of HIVST.

Dengue is one of the most important vector-borne diseases worldwide and is a significant public health problem in the tropics. Mosquito control continues to be the primary approach to reducing the disease burden and spread of dengue virus (DENV). Aside from the traditional larviciding and adulticiding interventions, autodissemination using pyriproxyfen-treated (AD-PPF) ovitraps is one of the promising methods to complement existing vector control strategies. Our paper assessed the efficacy of AD-PPF in reducing DENV infections in two barangays in Parañaque City. Using saliva samples from the participants from both the control and intervention sites, we collected the seroprevalence data for three months in each of the two years. Spatial analysis was conducted to determine hotspot areas and identify DENV infection distributions across the trial periods. The results showed that the intervention site was identified as having a clustering of DENV infections in Month 0 of Year 1 and shifted to a random dispersion of dengue cases at the end of Month 3 in Year 2. The disappearance of the clustering of the intervention site translates to a decrease in the cases of DENV infection relative to the control site. Furthermore, we also identified that DENV transmission occurred at a small-scale level that did not go beyond 86 m. In conclusion, AD-PPF is suggested to be an effective strategy and may be used as an additional vector control approach, albeit based on this short-term implementation.
RESUMEN
BACKGROUND: Transgender individuals are considered at high risk of contracting HIV infection. Integrating HIV testing and counseling (HTC) services into current transgender health programs is necessary to increase its uptake. Our study aimed to describe the characteristics of trans men (TM) and trans women (TW) who accessed HTC services in a community-based transgender health center in Metro Manila, Philippines, and to examine the relationship between gender identity and their non-uptake of HIV testing. METHODS: We conducted a cross-sectional study of TM and TW seeking care from 2017 to 2019. Medical records of clients were reviewed to ascertain their age, gender identity, year and frequency of clinic visits, lifestyle factors, and non-uptake of HIV testing. The effect of gender identity on the non-uptake of HIV testing was estimated using a generalized linear model with Poisson distribution, log link function, and a robust variance, adjusted for confounding variables. RESULTS: Five hundred twenty-five clients were included in the study, of which about 82.3% (432/525) of the clients declined the HTC services being offered. In addition, the prevalence of non-uptake of HIV testing was 48% higher (Adjusted Prevalence Ratio: 1.48; 95% Confidence Interval: 1.31-1.67) among TM compared to TW. Approximately 3.7% (1/27) and 10.6% (7/66) of the TM and TW, respectively, who accessed the HTC services were reactive. Moreover, most reactive clients were on treatment 87.5% (7/8); three were already virally suppressed, four were on ART but not yet virally suppressed, and one TW client was lost to follow up. CONCLUSION: The non-uptake of HTC service of TM and TW is high. HIV program implementers should strategize solutions to reach this vulnerable population for increased and better HTC service uptake and linkage to care.

Dengue is a viral mosquito-borne disease that rapidly spreads in tropical and subtropical countries, including the Philippines. One of its most distinguishing characteristics is the ability of the Dengue Virus (DENV) to easily surpass the innate responses of the body, thus activating B cells of the adaptive immunity to produce virus-specific antibodies. Moreover, Dengvaxia® is the only licensed vaccine for DENV, but recent studies showed that seronegative individuals become prone to increased disease severity and hospitalization. Owing to this limitation of the dengue vaccine, this study determined and compared consensus and unique B cell epitopes among each DENV (1-4) Philippine isolate to identify potential areas of interest for future vaccine studies and therapeutic developments. An in silico-based epitope prediction of forty (40) DENV 1-4 strains, each serotype represented by ten (10) sequences from The National Center for Biotechnology Information (NCBI), was conducted using Kolaskar and Tongaonkar antigenicity, Emini surface accessibility, and Parker hydrophilicity prediction in Immune Epitope Database (IEDB). Results showed that five (5) epitopes were consensus for DENV-1 with no detected unique epitope, one (1) consensus epitope for DENV-2 with two (2) unique epitopes, one (1) consensus epitope for DENV-3 plus two (2) unique epitopes, and two (2) consensus epitopes and one (1) unique epitope for DENV-4. The findings of this study would contribute to determining potential vaccine and diagnostic marker candidates for further research studies and immunological applications against DENV (1-4) Philippine isolates.
RESUMEN
INTRODUCTION: The COVID-19 pandemic declared by the WHO has affected many countries rendering everyday lives halted. In the Philippines, the lockdown quarantine protocols have shifted the traditional college classes to online. The abrupt transition to online classes may bring psychological effects to college students due to continuous isolation and lack of interaction with fellow students and teachers. Our study aims to assess Filipino college students' mental health status and to estimate the effect of the COVID-19 pandemic, the shift to online learning, and social media use on mental health. In addition, facilitators or stressors that modified the mental health status of the college students during the COVID-19 pandemic, quarantine, and subsequent shift to online learning will be investigated. METHODS AND ANALYSIS: Mixed-method study design will be used, which will involve: (1) an online survey to 2,100 college students across the Philippines; and (2) randomly selected 20-40 key informant interviews (KIIs). Online self-administered questionnaire (SAQ) including Depression, Anxiety, and Stress Scale (DASS-21) and Brief-COPE will be used. Moreover, socio-demographic factors, social media usage, shift to online learning factors, family history of mental health and COVID-19, and other factors that could affect mental health will also be included in the SAQ. KIIs will explore factors affecting the student's mental health, behaviors, coping mechanism, current stressors, and other emotional reactions to these stressors. Associations between mental health outcomes and possible risk factors will be estimated using generalized linear models, while a thematic approach will be made for the findings from the KIIs. Results of the study will then be triangulated and summarized. ETHICS AND DISSEMINATION: Our study has been approved by the University of the Philippines Manila Research Ethics Board (UPMREB 2021-099-01). The results will be actively disseminated through conference presentations, peer-reviewed journals, social media, print and broadcast media, and various stakeholder activities.

INTRODUCTION: The novel (COVID-19 was first reported to have originated in Wuhan, China, in December 2019. This new strain, SARS-CoV-2, has spread rapidly worldwide, prompting the WHO to declare the COVID-19 outbreak a global pandemic. The main objective of this cohort study is to determine the risk factors of COVID-19, the modes of COVID-19 vertical transmission, and the maternal and fetal outcomes among non-pregnant and pregnant women and their fetuses. METHODS AND ANALYSIS: This is a multicentre epidemiological study that will involve a prospective cohort. COVID-19 status among consulting non-pregnant and pregnant women in public hospitals in Manila, Philippines, will be determined and monitored for 6-12 months. Swab specimens from the nasopharynx, cervix, rectum, amniotic fluid, placenta, cord blood and breastmilk will be collected during consult and admission for reverse transcription-PCR (RT-PCR) testing. Blood will be collected during the postdelivery period to monitor the women and their neonates for any undue development and determine the antibody development to indicate an infective or non-infective state. Evidence of vertical transmission will be explored with the presence or absence of the virus using the maternal and fetal neonatal RT-PCR and lateral flow antibody status. Descriptive and inferential statistics will be done, including the associations between exposures and risk factors, description of clinical characteristics, and the COVID-19 status of the participants. ETHICS AND DISSEMINATION: The Single Joint Research Ethics Board of the Department of Health has approved this protocol (SJREB 2020-30). The study results will be disseminated through conference presentations, peer-reviewed articles, and various stakeholder public forums and activities.

OBJECTIVES: Our study identified barriers and facilitators in implementing HIV self-testing (HIVST), including the perceptions of men-having-sex-with-men (MSM) and transgender women (TGW) on HIVST. Furthermore, we explored the current knowledge, practices and potential of HIVST among the MSM and TGW populations. DESIGN: Qualitative in-depth key informant interviews were administered using semistructured interviews administered in both English and Filipino. Thematic analysis of the findings was done after transcribing all audio recordings. SETTING: The study was done in the National Capital Region (NCR), Philippines using online video conferencing platforms due to mobility restrictions and lockdowns caused by the COVID-19 pandemic. PARTICIPANTS: All study participants were either MSM or TGW, 18-49 years old and residing/working in NCR. Exclusion criteria include biologically born female and/or currently on pre-exposure prophylaxis, antiretroviral therapy medications or an HIV-positive diagnosis. RESULTS: Twenty informants were interviewed, of which 75% were MSM, and most of them preferred the use of HIVST. Facilitators and barriers to the use of HIVST were grouped into three main themes: Acceptability, distribution and monitoring and tracking. Convenience and confidentiality, overcoming fears and normalisation of HIV testing services (HTS) in the country were the participants' perceived facilitators of HIVST. In contrast, lack of privacy and maintenance of confidentiality during kit delivery were perceived as barriers in HIVST implementation. Moreover, social media was recognised as a powerful tool in promoting HIVST. The use of a welcoming tone and positive language should be taken into consideration due to the prevalent HIV stigma. CONCLUSIONS: The identified facilitators and barriers from the study may be considered by the Philippine HTS programme implementers. The HIVST strategy may complement the current HTS. It will be very promising to involve the MSM and TGW communities and other key populations to know their HIV status by bringing testing closer to them.

BACKGROUND: More information is needed about gender-affirming surgery (GAS) in the Philippines because of many self- or peer-prescribed gender-affirming procedures among transgender people. AIM: To assess the desire of transgender adults for GAS, determined the prevalence, and evaluated factors associated with the desire. METHODS: We did a retrospective study of medical charts of 339 transgender men (TGM) and 186 transgender women (TGW) who attended clinical services at Victoria by LoveYourself, a transgender-led community-based clinic in Metro Manila, from March 2017 to December 2019. The medical charts were reviewed to ascertain data on gender dysphoria (GD), clinical and sociodemographic characteristics, health-seeking behaviors, and gender-affirmation-related practices, including the use of gender-affirming hormone therapy (GAHT). We also estimated the prevalence and explored factors associated with the desire for GAS using generalized linear models with a Poisson distribution, log link function, and a robust variance. MAIN OUTCOME MEASURES: Our primary outcome was the self-reported desire for GAS. RESULTS: Almost half were already on GAHT, of whom 93% were self-medicating. Our study's prevalence of GD is 95% and nearly 3 in 4 desire GAS. The prevalence of desiring GAS was related to the specific surgical procedure chosen. Transgender adults opting for breast surgery and genital surgeries have 8.06 [adjusted prevalence ratio, (aPR): 8.06; 95% Confidence Interval, (CI): 5.22-12.45; P value < .001] and 1.19 (aPR: 1.19; 95% CI: 1.11-1.28; P value < .001) times higher prevalence of GAS desire, respectively, compared with otherwise not opting for those procedures. Moreover, the prevalence of GAS desire was higher among patients with GD (aPR 1.09; 95% CI: 1.01-1.18; P value = .03) than individuals without GD. CLINICAL TRANSLATION: Providers' awareness of patients' desires, values, and health-seeking preferences could facilitate differentiated guidance on their gender affirmation. STRENGTHS AND LIMITATIONS: This quantitative study is the first to explore gender-affirming practices among transgender adults in the Philippines and provide significant insights into their healthcare needs. Our study focused only on TGM and TGW and did not reflect the other issues of transgender people outside of Metro Manila, Philippines. Furthermore, our retrospective study design may have missed essential predictors or factors not captured in the medical charts; hence, our study could never dismiss confounding factor bias due to unmeasured or residual confounding factors. CONCLUSIONS: There is a high prevalence of self- and peer-led attempts from TGM and TGW to facilitate the gender transition, with the desire for GAS being significantly associated with GD and by which specific surgical procedure is chosen.

RESUMEN
Our study assessed the impact of using ovitraps with pyriproxyfen on mosquito populations and the feasibility of using human saliva samples to test for seroconversion to dengue virus (DENV). We used a quasi-experimental research design by forming the intervention (n = 220) and the control (n = 223) groups in neighboring Taguig City, Philippines, over 4 months. Socio-demographic data, entomological indices, and IgG antibodies against DENV were measured. Associations between the implementation of ovitraps dosed with pyriproxyfen and mosquito densities (percentage positive ovitraps and container indices) and DENV seroconversion were calculated post-intervention in Months 2, 3, and 4. Among the participants recruited at baseline, 17 and 13 were seropositive for dengue (DENV) in the intervention and control groups, respectively. Both entomological indices were lower in the treated area than the control site at post-intervention Months 2, 3, and 4, but not earlier. Dengue seroconversions rates decreased in the treated population, but not significantly so. In conclusion, the use of PPF-treated ovitraps may have impacted the mosquito population, but not seroconversion rates. Compliance in providing saliva samples and the ability to detect IgG antibodies within these samples was encouraging and suggests that further studies on larger populations for longer durations are warranted.

We examined the relationships between blood heavy metals [cadmium (B-Cd), mercury (B-Hg), and lead (B-Pb)] and heart rate-corrected QT interval (QTc), JT interval (JTc), and QRS complex duration (QRSc), electrocardiogram markers of ventricular repolarization and depolarization among 60 traffic enforcers in the MMDA traffic enforcers' health study. We fitted regression models to estimate the mean change effect on QTc, JTc, and QRSc, of B-Cd, B-Hg, and B-Pb concentrations, adjusted for potential confounding factors. We looked at effect modification by sex and smoking status. An interquartile range increase in B-Cd (0.9 µg/L) was related to a 6.6% increase in mean QRSc [95% confidence interval (CI): 2.5, 10.8], and a 1.7% increase in mean QTc (95% CI: 0.2, 3.3). We also found that the associations between B-Cd and QRSc and QTc were higher among participants who were never smokers than ever smokers. Moreover, the association between B-Cd and QRSc was also higher among males than females.

Identification of delay barriers to care is essential for an effective and efficient healthcare service delivery. In this study, we described the delay in care among parents of the patients seeking treatment for dengue. We also examined the factors affecting the severity of dengue (dengue with warning signs; severe dengue). A convergent parallel design mixed-method approach using Key Informant Interviews (KII) and a survey guided by the Three-Delay Model were conducted among 24 respondents at the National Children's Hospital (NCH). Coding and thematic analysis using NVIVO and bivariable generalized linear models with a Poisson distribution and robust variance were utilized to analyze the KII transcripts and survey data, respectively. Results showed that financial constraints and previous dengue infection (first delay), mode of transportation, traffic density, and location (second delay), and hospital capacity (third delay) influenced the overall delay uncertainty in seeking care treatment for dengue infection. Furthermore, our bivariable analysis showed that travel time to NCH and place of residency, service given from previous health facilities, and parents' educational background were associated and played a role in the severity of dengue infection. Interventions focused on the identified factors contributing to delayed care should be made to avoid unwanted clinical outcomes.

Exposure to traffic-related air pollution is linked with acute alterations in blood pressure (BP). We examined the cumulative short-term effect of black carbon (BC) exposure on systolic (SBP) and diastolic (DBP) BP and assessed effect modification by participant characteristics. SBP and DBP were repeatedly measured on 152 traffic enforcers. Using a linear mixed-effects model with random intercepts, quadratic (QCDL) and cubic (CCDL) constrained distributed lag models were fitted to estimate the cumulative effect of BC concentration on SBP and DBP during the 10 hours (daily exposure) and 7 days (weekly exposure) before the BP measurement. Ambient BC was related to increased BP with QCDL models. An interquartile range change in BC cumulative during the 7 days before the BP measurement was associated with increased BP (1.2% change in mean SBP, 95% confidence interval (CI), 0.1 to 2.3; and 0.5% change in mean DBP, 95% CI, -0.8 to 1.7). Moreover, the association between the 10-h cumulative BC exposure and SBP was stronger for female (4.0% change, 95% CI: 2.1-5.9) versus male and for obese (2.9% change, 95% CI: 1.0-4.8) vs. non-obese traffic enforcers. Short-term cumulative exposure to ambient traffic-related BC could bring about cardiovascular diseases through mechanisms involving increased BP.

BACKGROUND: Several studies have linked social media use to increased risks for anxiety and depression. Cargo seafaring is one occupation prone to constant mental health instability due to workload, social isolation, and harsh working conditions. We examined the effect of daily social media exposure, occupational experience, and socioeconomic factors on anxiety and depression disorders among cargo seafarers. MATERIALS AND METHODS: We assessed the anxiety and depression disorders of 153 cargo seafarers using Generalised Anxiety Disorder-7 and Patient Health Questionnaire-9 scales. We fitted generalised linear models to estimate associations between depression and anxiety disorders and daily social media exposure, occupational experience, and socioeconomic factors. RESULTS: Approximately 30% and 37% of the seafarers had mild, moderate, or severe anxiety and depression disorders. The prevalence of anxiety was 2.68 times higher (adjusted prevalence ratio [aPR] 2.68, 95% confidence interval [95% CI] 1.30-5.50) and 2.27 times higher (aPR 2.27; 95% CI 1.12-4.62) among seafarers who spend > 2 to 4 hours and > 4 hours each day, respectively, on social media compared to seafarers who spend only up to 2 hours. In addition, seafarers who were on social media daily for > 2 to 4 hours (aPR 1.49; 95% CI 0.86-2.60) and > 4 hours (aPR 1.34; 95% CI 0.75-2.40) had a higher prevalence of depression compared to seafarers who were on social media daily for only up to 2 hours. Non-Catholics or seafarers with ≤ 10 years of occupational experience had a higher prevalence for anxiety and depression disorders than Catholics or seafarers with > 10 years of occupational experience. CONCLUSIONS: Daily social media exposure for > 2 hours, working for ≤ 10 years, or being a non-Catholic may contribute to the increase in the seafarers' susceptibility to depression and anxiety disorders. The establishment of support groups for cargo seafarers is warranted to promote mental health awareness and well-being.
