Depression and associated factors in medical students in Acapulco during the COVID-19 pandemic: A cross-sectional study.

BACKGROUND: Depression is common in medical students and the Mexican state of Guerrero has the highest rates of depression in the country. Acapulco, the seat of the state medical school, is a tourist destination that experienced early high rates of COVID-19. The COVID-19 pandemic closed all schools in Mexico, obliging a shift from face-to-face to virtual education. In this new context, medical students faced challenges of online teaching including inadequate connectivity and access technologies. Prolonged isolation during the pandemic may have had additional mental health implications. AIM: Assess depression prevalence and its associated factors affecting medical students in Acapulco, Mexico during the COVID-19 pandemic. METHODS: A cross-sectional survey of students of the Faculty of Medicine of the Universidad Autónoma de Guerrero, in November 2020. After informed consent, students completed a self-administered questionnaire collating socio-demographic, academic and clinical variables, major life events and changes in mood. The Beck inventory provided an assessment of depression. Bivariate and multivariate analyses relied on the Mantel-Haenszel procedure to identify factors associated with depression. We estimated the odds ratio (OR) and 95% confidence intervals. RESULTS: 33.8% (435/1288) of student questionnaires showed evidence of depression in the two weeks prior to the study, with 39.9% (326/817) of young women affected. Factors associated with depression included female sex (OR 1.95; 95%CI 1.48-2.60), age 18-20 years (OR 1.36; 95%CI 1.05-1.77), perceived academic performance (OR 2.97; 95%CI 2.16-4.08), perceived economic hardship (OR 2.18; 95%CI 1.57-3.02), and a family history of depression (OR 1.85; 95%CI 10.35-2.54). Covid-19 specific factors included a life event during the pandemic (OR 1.99; 95%CI 1.54-2.59), connectivity problems during virtual classes and difficulties accessing teaching materials (OR 1.75; 95%CI 1.33-2.30). CONCLUSIONS: The high risk of depression in medical students during the COVID-19 pandemic was associated with perceived academic performance and technical barriers to distance learning, in addition to known individual and family factors. This evidence may be useful for the improvement of programs on prevention and control of depression in university students.

Safe birth in cultural safety in southern Mexico: a pragmatic non-inferiority cluster-randomised controlled trial.

BACKGROUND: Available research on the contribution of traditional midwifery to safe motherhood focuses on retraining and redefining traditional midwives, assuming cultural prominence of Western ways. Our objective was to test if supporting traditional midwives on their own terms increases cultural safety (respect of Indigenous traditions) without worsening maternal health outcomes. METHODS: Pragmatic parallel-group cluster-randomised controlled non-inferiority trial in four municipalities in Guerrero State, southern Mexico, with Nahua, Na savi, Me'phaa and Nancue ñomndaa Indigenous groups. The study included all pregnant women in 80 communities and 30 traditional midwives in 40 intervention communities. Between July 2015 and April 2017, traditional midwives and their apprentices received a monthly stipend and support from a trained intercultural broker, and local official health personnel attended a workshop for improving attitudes towards traditional midwifery. Forty communities in two control municipalities continued with usual health services. Trained Indigenous female interviewers administered a baseline and follow-up household survey, interviewing all women who reported pregnancy or childbirth in all involved municipalities since January 2016. Primary outcomes included childbirth and neonatal complications, perinatal deaths, and postnatal complications, and secondary outcomes were traditional childbirth (at home, in vertical position, with traditional midwife and family), access and experience in Western healthcare, food intake, reduction of heavy work, and cost of health care. RESULTS: Among 872 completed pregnancies, women in intervention communities had lower rates of primary outcomes (perinatal deaths or childbirth or neonatal complications) (RD -0.06 95%CI - 0.09 to - 0.02) and reported more traditional childbirths (RD 0.10 95%CI 0.02 to 0.18). Among institutional childbirths, women from intervention communities reported more traditional management of placenta (RD 0.34 95%CI 0.21 to 0.48) but also more non-traditional cold-water baths (RD 0.10 95%CI 0.02 to 0.19). Among home-based childbirths, women from intervention communities had fewer postpartum complications (RD -0.12 95%CI - 0.27 to 0.01). CONCLUSIONS: Supporting traditional midwifery increased culturally safe childbirth without worsening health outcomes. The fixed population size restricted our confidence for inference of non-inferiority for mortality outcomes. Traditional midwifery could contribute to safer birth among Indigenous communities if, instead of attempting to replace traditional practices, health authorities promoted intercultural dialogue. TRIAL REGISTRATION: Retrospectively registered ISRCTN12397283 . Trial status: concluded.

In many Indigenous communities, traditional midwives support mothers during pregnancy, childbirth, and some days afterwards. Research involving traditional midwives has focused on training them in Western techniques and redefining their role to support Western care. In Guerrero state, Mexico, Indigenous mothers continue to trust traditional midwives. Almost half of these mothers still prefer traditional childbirths, at home, in the company of their families and following traditional practices. We worked with 30 traditional midwives to see if supporting their practice allowed traditional childbirth without worsening mothers' health. Each traditional midwife received an inexpensive stipend, a scholarship for an apprentice and support from an intercultural broker. The official health personnel participated in a workshop to improve their attitudes towards traditional midwives. We compared 40 communities in two municipalities that received support for traditional midwifery with 40 communities in two municipalities that continued to receive usual services. We interviewed 872 women with childbirth between 2016 and 2017. Mothers in intervention communities suffered fewer complications during childbirth and had fewer complications or deaths of their babies. They had more traditional childbirths and fewer perineal tears or infections across home-based childbirths. Among those who went to Western care, mothers in intervention communities had more traditional management of the placenta but more non-traditional cold-water baths. Supporting traditional midwifery increased traditional childbirth without worsening health outcomes. The small size of participating populations limited our confidence about the size of this difference. Health authorities could promote better health outcomes if they worked with traditional midwives instead of replacing them.

Factors Associated with Chikungunya Relapse in Acapulco, Mexico: A Cross-Sectional Study.

Objective: To estimate the occurrence of self-reported chikungunya relapse and identify associated factors. Materials and Methods: A cross-sectional study in December 2015 included 1305 homes in eight urban clusters considered representative of Acapulco in southern Mexico. Administered questionnaires collated information on 5870 individuals, including sociodemographic variables, a history of chronic conditions, and the self-reporting of chikungunya. Bivariate and multivariate analyses relied on a cluster-adjusted Mantel-Haenszel procedure to identify the factors associated with chikungunya and its relapse. Results: Some 66% (3531/5870) of the population reported suffering chikungunya and 31.1% (1098/3531) reported a relapse. Factors associated with relapse included the severity of the chikungunya case (odds ratio [OR]: 3.35; clusters adjusted 95% confidence interval [95% CIca]: 3.16-3.55); history of arthralgia (OR: 2.96; 95% CIca: 2.27-3.86); age 30 years or older (OR: 1.85; 95% CIca: 1.72-1.98); female (OR: 1.64; 95% CIca: 1.42-1.90); and higher education households (OR: 1.18; 95% CIca: 1.11-1.27). Conclusions: The high occurrence of chikungunya and its relapse are a public health problem. The factors associated with relapse do not immediately suggest specific prevention strategies but emphasize the dire need for effective approaches to vector control.

Insuficiencia renal oculta y factores asociados en pacientes con enfermedades crónicas / Occult renal failure and associated factors in patients with chronic conditions

Resumen Introducción: El diagnóstico oportuno y la intervención terapéutica temprana disminuyen la mortalidad prematura asociada con insuficiencia renal crónica. Objetivo: Identificar la prevalencia y factores asociados con insuficiencia renal oculta en pacientes con enfermedades crónicas. Método: Estudio transversal de 1268 pacientes con diabetes mellitus tipo 2 e hipertensión arterial sistémica. Se usó un instrumento de medición con preguntas sobre factores asociados como artrosis, tratamiento de padecimiento crónico, tabaquismo, ingesta de analgésicos, alcoholismo, índice de masa corporal, actividad física y niveles séricos de glucosa, colesterol y triglicéridos. Resultados: La prevalencia de insuficiencia renal oculta fue de 13.2 % (167/1268), 13.4 % en pacientes diabéticos (117/876) y 14.9 % en hipertensos (150/1010). En el analisis multivariado, los factores asociados con insuficiencia renal oculta fueron edad > 60 años (RMa = 1.96, IC 95 % = 1.22-2.49), sexo femenino (RMa = 2.17, IC 95 % = 1.30-2.82), padecer hipertensión arterial sistémica (RMa = 1.96, IC 95 % = 1.22-2.50) y no tener sobrepeso u obesidad (RMa = 0.49, IC 95 % = 0.41-0.8). Conclusiones: La prevalencia de insuficiencia renal oculta fue de 13 %. Los pacientes mayores de 60 años, con sobrepeso u obesidad e hipertensión arterial sistémica deben ser examinados detalladamente por el médico familiar para la detección temprana de insuficiencia renal oculta.

Abstract Introduction: Timely diagnosis and early therapeutic intervention reduce premature mortality associated with chronic renal failure. Objective: To identify the prevalence and factors associated with occult renal failure in patients with chronic diseases. Method: Cross-sectional study of 1268 patients with type 2 diabetes mellitus and systemic arterial hypertension. A measuring instrument with questions about associated factors such as osteoarthritis, treatment of chronic conditions, smoking, analgesic consumption, alcoholism, body mass index, physical activity and serum glucose, cholesterol and triglyceride levels was used. Results: The prevalence of occult renal failure was 13.2 % (167/1,268), 13.4 % in diabetic patients (117/876) and 14.9 % in hypertensive patients (150/1,010). In the multivariate analysis, the factors associated with occult renal failure were being older than 60 years (aOR = 1.96, 95 % CI = 1.22-2.49), belonging to the female gender (aOR = 2.17, 95 % CI = 1.30-2.82), suffering from systemic arterial hypertension (aOR = 1.96, 95% CI = 1.22-2.50) and not having overweight/obesity (aOR = 0.49, 95 % CI = 0.41-0.8). Conclusions: The prevalence of occult renal failure was 13 %. Female patients older than 60 years with overweight/obesity and systemic arterial hypertension should be examined in detail by the family doctor for occult renal failure early detection.

Household costs for personal protection against mosquitoes: secondary outcomes from a randomised controlled trial of dengue prevention in Guerrero state, Mexico.

BACKGROUND: Dengue is a serious public health issue that affects households in endemic areas in terms of health and also economically, imposing costs for prevention and treatment of cases. The Camino Verde cluster-randomised controlled trial in Mexico and Nicaragua assessed the impact of evidence-based community engagement in dengue prevention. The Mexican arm of the trial was conducted in 90 randomly selected communities in three coastal regions of Guerrero State. This study reports an analysis of a secondary outcome of the trial: household use of and expenditure on anti-mosquito products. We examined whether the education and mobilisation activities of the trial motivated people to spend less on anti-mosquito products. METHODS: We carried out a household questionnaire survey in the trial communities in 2010 (12,312 households) and 2012 (5349 households in intervention clusters, 5142 households in control clusters), including questions about socio-economic status, self-reported dengue illness, and purchase of and expenditure on insecticide anti-mosquito products in the previous month. We examined expenditures on anti-mosquito products at baseline in relation to social vulnerability and we compared use of and expenditures on these products between intervention and control clusters in 2012. RESULTS: In 2010, 44.2% of 12,312 households reported using anti-mosquito products, with a mean expenditure of USD4.61 per month among those who used them. Socially vulnerable households spent less on the products. In 2012, after the intervention, the proportion of households who purchased anti-mosquito products in the last month was significantly lower in intervention clusters (47.8%; 2503/5293) than in control clusters (53.3%; 2707/5079) (difference - 0.05, 95% CIca -0.100 to -0.010). The mean expenditure on the products, among those households who bought them, was USD6.43; 30.4% in the intervention clusters and 36.7% in the control clusters spent more than this (difference - 0.06, 95% CIca -0.12 to -0.01). These expenditures on anti-mosquito products represent 3.3% and 3.8% respectively of monthly household income for the poorest 10% of the population in 2012. CONCLUSIONS: The Camino Verde community mobilisation intervention, as well as being effective in reducing dengue infections, was effective in reducing household use of and expenditure on insecticide anti-mosquito products.

Which green way: description of the intervention for mobilising against Aedes aegypti under difficult security conditions in southern Mexico.

BACKGROUND: Community mobilisation for prevention requires engagement with and buy in from those communities. In the Mexico state of Guerrero, unprecedented social violence related to the narcotics trade has eroded most community structures. A recent randomised controlled trial in 90 coastal communities achieved sufficient mobilisation to reduce conventional vector density indicators, self-reported dengue illness and serologically proved dengue virus infection. METHODS: The Camino Verde intervention was a participatory research protocol promoting local discussion of baseline evidence and co-design of vector control solutions. Training of facilitators emphasised community authorship rather than trying to convince communities to do specific activities. Several discussion groups in each intervention community generated a loose and evolving prevention plan. Facilitators trained brigadistas, the first wave of whom received a small monthly stipend. Increasing numbers of volunteers joined the effort without pay. All communities opted to work with schoolchildren and for house-to-house visits by brigadístas. Children joined the neighbourhood vector control movements where security conditions permitted. After 6 months, a peer evaluation involved brigadista visits between intervention communities to review and to share progress. DISCUSSION: Although most communities had no active social institutions at the outset, local action planning using survey data provided a starting point for community authorship. Well-known in their own communities, brigadistas faced little security risk compared with the facilitators who visited the communities, or with governmental programmes. We believe the training focus on evidence-based dialogue and a plural community ownership through multiple design groups were key to success under challenging security conditions.

Household costs of dengue illness: secondary outcomes from a randomised controlled trial of dengue prevention in Guerrero state, Mexico.

BACKGROUND: Dengue is a serious public health problem with an important economic impact. This study used data from a cluster randomised controlled trial of community mobilisation for dengue prevention to estimate the household costs of treatment of dengue illness. It examined the economic impact of the trial intervention in the three coastal regions of Mexico's Guerrero State. METHODS: The 2010 baseline survey covered households in a random sample of 90 clusters in the coastal regions; the clusters were randomly allocated to intervention or control and re-surveyed in 2012. The surveys asked about dengue cases in the last 12 months, expenditures on their treatment, and work or school days lost by patients and care givers. We did not assign monetary value to days lost, since a lost day to a person of low earning power is of equal or higher value to that person than to one who earns more. RESULTS: The 12,312 households in 2010 reported 1020 dengue cases in the last 12 months (1.9% of the sample population). Most (78%) were ambulatory cases, with a mean cost of USD 51 and 10.8 work/school days, rising to USD 96 and 11.4 work/school days if treated by a private physician. Hospitalised cases cost USD 28-94 in government institutions and USD 392 in private hospitals (excluding additional inpatient charges), as well as 9.6-17.3 work/school days. Dengue cases cost households an estimated 412,825 work/school days throughout the three coastal regions. In the follow up survey, 6.1% (326/5349) of households in intervention clusters and 7.9% (405/5139) in control clusters reported at least one dengue case. The mean of days lost per case was similar in intervention and control clusters, but the number of days lost from dengue and all elements of costs for dengue cases per 1000 population were lower in intervention clusters. If the total population of the three coastal regions had received the intervention, some 149,401 work or school days lost per year could have been prevented. CONCLUSION: The economic effect of dengue on households, including lost work days, is substantial. The Camino Verde trial intervention reduced household costs for treatment of dengue cases. TRIAL REGISTRATION: The trial was registered as ISRCTN:27,581,154 .
