Diabetes in Mexico: cost and management of diabetes and its complications and challenges for health policy

Prevalence of nephropathy among diabetic patients in North American region: A systematic review and meta-analysis

BACKGROUND

Nephropathy is one of the most common microvascular impediments of diabetes mellitus. In this study, we aimed to estimate the prevalence of nephropathy in diabetic patients across the North American region.

METHODS

Eligible studies were screened out from 3 electronic databases, for example, PubMed, Google Scholar, and ScienceDirect using specific search keywords based on the eligibility criteria. Extracting the data from the included studies publication bias, quality assessment, outlier investigation, and meta-analysis was done followed by the subgroup analysis. A total of 11 studies met the study inclusion criteria. Meta-analysis was performed with the extracted data.

RESULTS

Pooled prevalence of 28.2% (95% confidence interval [CI]: 19.7-36.7) with a high rate of heterogeneity (I2 = 100%) was identified. The pooled prevalence of nephropathy among diabetic patients in the United States of America, Canada, and Mexico was 24.2% (95% CI: 13.8-34.5), 31.2% (95% CI: 25.8-36.5), and 31.1% (95% CI: 20.8-41.5), respectively.

CONCLUSION

The prevalence of nephropathy among diabetic patients was found lower in the United States of America as compared to Canada and Mexico. Besides, the pooled prevalence of the North American region was found to be lower as compared to the African, European, and Asian regions. Minimizing the pathogenic factors, sufficient diagnostic, healthcare facilities, and awareness are recommended to improve the situation.

Self-Reported Diabetes in Older Adults: A Comparison of Prevalence and Related Factors in the Mexican Health and Aging Study (2015, 2018, and 2021)

Aim: To estimate the prevalence and factors associated with diabetes among older adults and compare the prevalence rate of a three-round national survey of the Mexican Health and Aging Study (MHAS). Methods: A cross-sectional study was conducted with data obtained from MHAS 2015 (n = 8167), 2018 (n = 7854), and 2021 (n = 8060), which comprised a nationally representative sample of older adults in Mexico. The measures included sociodemographic characteristics and health. A binary logistic regression model was used to identify the association between independent variables and self-reported diabetes. Results: The prevalence of diabetes was 26.3%, 27.7%, and 28.1% in 2015, 2018, and 2021, respectively. This prevalence decreased with age and was higher for female, urban older adults, those with multimorbidity, a lower level of education, and without social security coverage for the three years. Age was associated with a lower possibility of presenting diabetes ([OR = 0.79[0.71-0.89]] and [OR = 0.41[0.33-0.52]] in groups aged 75-84 years and ≥85 years, respectively). Females continue to be more likely to present diabetes than males (OR = 1.39 [95% CI 1.25-1.55]). Older adults living in rural areas are 20% less likely to present diabetes than those living in urban areas (OR = 0.80 [95% CI 0.69-0.93]). Uninsured older adults (OR = 1.35 [95% CI 1.20-1.53]), those who wear glasses (OR = 1.23 [95% CI 1.16-1.30]), those with multimorbidity (OR = 1.13 [95% CI 1.01-1.27]), and those who currently drink alcohol (OR = 1.12 [95% CI 1.00-1.25]) were significantly more likely to have diabetes. Conclusion: An elevated prevalence of diabetes was found in older adults in Mexico, while not having access to social security was associated with a higher possibility of presenting diabetes and living in a rural area was associated with a lower possibility of presenting diabetes. Detection, prevention, and control programs should be implemented to reduce the incidence and severity of the disease in older adults and, thus, prevent its associated complications.

Hospital care direct costs due to ambulatory care sensitive conditions related to diabetes mellitus in the Mexican public healthcare system

BACKGROUND

Hospitalizations for ambulatory care sensitive conditions (ACSC) incur substantial costs on the health system that could be partially avoided with adequate outpatient care. Complications of chronic diseases, such as diabetes mellitus (DM), are considered ACSC. Previous studies have shown that hospitalizations due to diabetes have a significant financial burden. In Mexico, DM is a major health concern and a leading cause of death, but there is limited evidence available. This study aimed to estimate the direct costs of hospitalizations by DM-related ACSC in the Mexican public health system.

METHODS

We selected three hospitals from each of Mexico's main public institutions: the Mexican Social Security Institute (IMSS), the Ministry of Health (MoH), and the Institute of Social Security and Services for State Workers (ISSSTE). We employed a bottom-up microcosting approach from the healthcare provider perspective to estimate the total direct costs of hospitalizations for DM-related ACSC. Input data regarding length of stay (LoS), consultations, medications, colloid/crystalloid solutions, procedures, and laboratory/medical imaging studies were obtained from clinical records of a random sample of 532 hospitalizations out of a total of 1,803 DM-related ACSC (ICD-10 codes) discharges during 2016.

RESULTS

The average cost per DM-related ACSC hospitalization varies among institutions, ranging from $1,427 in the MoH to $1,677 in the IMSS and $1,754 in the ISSSTE. The three institutions' largest expenses are LoS and procedures. Peripheral circulatory and renal complications were the major drivers of hospitalization costs for patients with DM-related ACSC. Direct costs due to hospitalizations for DM-related ACSC in these three institutions represent 1% of the gross domestic product (GDP) dedicated to health and social services and 2% of total hospital care expenses.

CONCLUSIONS

The direct costs of hospitalizations for DM-related ACSC vary considerably across institutions. Disparities in such costs for the same ACSC among different institutions suggest potential disparities in care quality across primary and hospital settings (processes and resource utilization), which should be further investigated to ensure optimal supply utilization. Prioritizing preventive measures for peripheral circulatory and renal complications in DM patients could be highly beneficial.

A systematic review of the economic burden of diabetes mellitus: contrasting perspectives from high and low middle-income countries

Introduction

Diabetes increases preventative sickness and costs healthcare and productivity. Type 2 diabetes and macrovascular disease consequences cause most diabetes-related costs. Type 2 diabetes greatly costs healthcare institutions, reducing economic productivity and efficiency. This cost of illness (COI) analysis examines the direct and indirect costs of treating and managing type 1 and type 2 diabetes mellitus.

Methodology

According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, Cochrane, PubMed, Embase, CINAHL, Scopus, Medline Plus, and CENTRAL were searched for relevant articles on type 1 and type 2 diabetes illness costs. The inquiry returned 873 2011-2023 academic articles. The study included 42 papers after an abstract evaluation of 547 papers.

Results

Most articles originated in Asia and Europe, primarily on type 2 diabetes. The annual cost per patient ranged from USD87 to USD9,581. Prevalence-based cost estimates ranged from less than USD470 to more than USD3475, whereas annual pharmaceutical prices ranged from USD40 to more than USD450, with insulin exhibiting the greatest disparity. Care for complications was generally costly, although costs varied significantly by country and problem type.

Discussion

This study revealed substantial heterogeneity in diabetes treatment costs; some could be reduced by improving data collection, analysis, and reporting procedures. Diabetes is an expensive disease to treat in low- and middle-income countries, and attaining Universal Health Coverage should be a priority for the global health community.

Present and future screening programs for diabetic retinopathy: a narrative review

Diabetes is a prevalent global concern, with an estimated 12% of the global adult population affected by 2045. Diabetic retinopathy (DR), a sight-threatening complication, has spurred diverse screening approaches worldwide due to advances in DR knowledge, rapid technological developments in retinal imaging and variations in healthcare resources.Many high income countries have fully implemented or are on the verge of completing a national Diabetic Eye Screening Programme (DESP). Although there have been some improvements in DR screening in Africa, Asia, and American countries further progress is needed. In low-income countries, only one out of 29, partially implemented a DESP, while 21 out of 50 lower-middle-income countries have started the DR policy cycle. Among upper-middle-income countries, a third of 59 nations have advanced in DR agenda-setting, with five having a comprehensive national DESP and 11 in the early stages of implementation.Many nations use 2-4 fields fundus images, proven effective with 80-98% sensitivity and 86-100% specificity compared to the traditional seven-field evaluation for DR. A cell phone based screening with a hand held retinal camera presents a potential low-cost alternative as imaging device. While this method in low-resource settings may not entirely match the sensitivity and specificity of seven-field stereoscopic photography, positive outcomes are observed.Individualized DR screening intervals are the standard in many high-resource nations. In countries that lacks a national DESP and resources, screening are more sporadic, i.e. screening intervals are not evidence-based and often less frequently, which can lead to late recognition of treatment required DR.The rising global prevalence of DR poses an economic challenge to nationwide screening programs AI-algorithms have showed high sensitivity and specificity for detection of DR and could provide a promising solution for the future screening burden.In summary, this narrative review enlightens on the epidemiology of DR and the necessity for effective DR screening programs. Worldwide evolution in existing approaches for DR screening has showed promising results but has also revealed limitations. Technological advancements, such as handheld imaging devices, tele ophthalmology and artificial intelligence enhance cost-effectiveness, but also the accessibility of DR screening in countries with low resources or where distance to or a shortage of ophthalmologists exists.

Prevalence of obesity, diabetes and hypertension in immigrant populations in northeastern Mexico

Introduction

Hispanic immigrants are a fast-growing population in the United States of America (USA) that disproportionately suffer from chronic diseases. Despite the increasing prevalence of obesity in Latin-American countries, only a few studies have examined the onset of chronic diseases in Mexican and Central American migrants in Mexico.

Objective

The objective of this study is to determine the prevalence of obesity, diabetes, and hypertension in Central American immigrants who are in the process of traveling through northeastern Mexico to the United States.

Methods

An observational, descriptive, cross-sectional study was conducted among migrants, mostly Central Americans. Migrants who agreed to participate in the study were interviewed face-to-face by researchers to obtain their sociodemographic data. To obtain the prevalence, many health indicators related to obesity, diabetes, and hypertension, including weight, height, fasting glucose, and blood pressure, were measured.

Results

In total, 520 migrants were interviewed; sociodemographic data indicated that most participants were men (76%), from Honduras (72.6%), single (61.2%), and have elementary level of education (48.6%). The somatometric evaluation revealed that 28.9% were diagnosed as overweight, 10.7% with obesity, and 3.3% with malnutrition. Of less prevalence, 8.8% were detected with hypertension and 4.6% had fasting hyperglycemia. The mean participant age was 29.11 ± 10.00 years. For each participant, the average weight was 66.72 ± 13.09 kg; the average height was 1.64 ± 0.08 m; the average body mass index (BMI) was 24.59 ± 4.32; the mean systolic and diastolic pressures were 116.26 ± 15.13 and 74 ± 9.65, respectively; and the average glycemia was 100.97 ± 21.99. El Salvador showed the highest proportion of people with diabetes (14.7%). Women who participated in this study had a higher proportion of obesity (23.4%, p = 0.02) and overweight (36.2%) than men (8.4 and 29.2%, respectively). People from Mexico, Nicaragua, and Honduras reported a high prevalence of overweight participants (63.6, 47.4, and 30.7%, respectively), while people from El Salvador and Nicaragua had a high prevalence of obese participants (23.5 and 21.1%, respectively).

Conclusion

We found significant differences in the rates of obesity, diabetes, and hypertension between groups of Central American migrants and their place of origin, age, educational level, and gender. Our findings highlight the importance of exploring differences within groups of Central American migrants traveling through northeastern Mexico to the United States, which may explain several health indicators.

Lessons learned from a peer-supported diabetes education program in two dissimilar Mayan communities

Background

A steady rise in type 2 diabetes (T2D) in Mexico over the last 30 years has led to 11.5 million Mexicans being affected by this condition. There is an urgent need to develop interventions to prevent complications of T2D. Diabetes self-management education is the cornerstone of promoting self-care. Among all educational strategies, peer support has shown to be an effective method to encourage ongoing self-management. However, customization of interventions for distinct communities is imperative, as failure to do so can hinder the intervention's effectiveness.

Methods

We implemented a two-year prospective randomized controlled community-based trial in Conkal, a Mayan community from Yucatan, Mexico. The intervention consisted of receiving either a culturally sensitive peer support on top of a diabetes self-management education group (PLG); or a diabetes self-management education group only (EOG; control group). The primary outcome was changes in glycated hemoglobin, while secondary outcomes encompassed changes in systolic and diastolic blood pressure, body mass index, and diabetes self-care practices. Data collection was performed at baseline and every four months during the study period.

Discussion

Our experiences have highlighted the significance of peer-leader support in cultivating diabetes self-care skills, particularly within smaller, underserved communities characterized by strong social and cultural ties. However, when applied in larger or suburban settings, selecting peer leaders should be meticulous, considering sectorization within specific neighborhoods to foster a sense of belonging and familiarity among natural community clusters. In larger settlemnts, factors such as transportation challenges, time limitations, caregiving obligations, limited venue access, and changes in session locations can drive program discontinuation. Additionally, individuals with lower educational attainment are more susceptible to abandonment. Notably, those with lower education, uncontrolled diabetes, and extended diabetes duration exhibit a greater potential for improving glycemic control than their counterparts.

Health and Productivity Benefits with Early Intensified Treatment in Patients with Type 2 Diabetes: Results from Korea

The available evidence suggests positive health outcomes associated with early treatment intensification in Type 2 diabetes mellitus (T2DM). Our study estimated the productivity effects arising from improved health correlated with early intensified treatment in T2DM in Korea. Using a recently published methodology and model, we investigated the association between early intensified treatment and the probability of experiencing fewer diabetes-related complication events. Treatment strategies leading to better health outcomes are expected to be associated with social value through increased participation in paid and unpaid work activities. Therefore, we translated the lower incidence of complications into monetary terms related to productivity for the Korean population. We quantified productivity by considering (a) absenteeism, (b) presenteeism, (c) permanent loss of labor force, and (d) activity restriction. Deterministic and probabilistic sensitivity analyses in the base case parameter were performed. Approximately, 1.7 thousand (standard deviation [SD] ±580 events) micro- and macrovascular complication events could potentially be avoided by early treatment intensification. This led to a societal gain attributed to increased productivity of 23 million USD (SD ± $8.2 million). This article demonstrates the likelihood of achieving better health and productivity through early intensified treatment in diabetes.

Trends in the mortality of diabetes in Mexico from 1998 to 2022: a joinpoint regression and age-period-cohort effect analysis

OBJECTIVE

The purpose was to analyze age-standardized trends in diabetes mortality rates (DMR) from 1998 to 2022, stratified by sex and Mexican state, and the effects attributable to age, period, and cohort by sex.

STUDY DESIGN

Joinpoint regression and age-period-cohort effect analysis.

METHODS

Based on the tenth revision of the International Classification of Diseases, E11, E12, E13, and E14 codes of the death certificate, a daily record of mortality was extracted from the death certificate attributable to diabetes as the main cause. From 1998 to 2022, sexes and ages (≥20 years) were used to calculate the crude mortality rates and standardized at the national and Mexican state levels. Additionally, the age-period-cohort model was used to examine age, period, and cohort effects.

RESULTS

From 1998 to 2005, the age-adjusted DMR increased by 3.6% (95% confidence interval [CI]: 2.7, 4.5) for the total population, as shown by the joinpoint regression analysis at a national level; from 2017 to 2020, it increased by 7.4% (95% CI: 0.6, 14.8). The DMR with the highest increase during the study period came mainly from states in the country's southeastern region, 2.3% to 3.7% per year. The net age and period effects showed that mortality increased with advancing age and with going time, respectively; and the net cohort effect revealed that mortality increased in more recent birth cohorts, mainly in men Rate Ratio (RR) = 2.37 (95% CI: 2.29, 2.46) vs RR = 1.13 (95% CI: 1.09, 1.17).

CONCLUSION

The DMR increased among older age groups. The period effect showed that mortality increased over time. Furthermore, the cohort effect showed that mortality increased in more recent birth cohorts, especially among men.

Impact of capitation prepayment on the medical expenses and health service utilization of patients with coronary heart disease: a community policy intervention program in a county in China

BACKGROUND

Medical costs have been rising rapidly in recent years, and China is controlling medical costs from the perspective of health insurance payments.

OBJECTIVES

To explore the impact of the capitation prepayment method on medical expenses and health service utilization of coronary heart disease (CHD) patients, which provides a scientific basis for further improvement of the payment approach.

METHODS

The diagnosis records of visits for CHD in the database from 2014 to 2016 (April to December each year) were selected, and two townships were randomly selected as the pilot and control groups. Propensity score matching (PSM) and difference-in-difference (DID) model were used to assess changes in outpatient and inpatient expenses and health service utilization among CHD patients after the implementation of the capitation prepayment policy.

RESULTS

There were eventually 3,900 outpatients and 664 inpatients enrolled in this study after PSM. The DID model showed that in the first year of implementing the reform, total outpatient expenses decreased by CNY 13.953, drug expenses decreased by CNY 11.289, as well as Medicare payments decreased by CNY 8.707 in the pilot group compared to the control group. In the second year of implementing the reform, compared with the control group, the pilot group had a reduction of CNY 3.123 in other expenses, and a reduction of CNY 6.841 in Medicare payments. There was no significant change in inpatient expenses in the pilot group compared to the control group, but there was an increase of 0.829 visits to rural medical institutions, and an increase of 0.750 visits within the county for inpatients.

CONCLUSIONS

The capitation prepayment method has been effective in controlling the outpatient expenses of CHD patients, as well as improving the medical service capacity of medical institutions within the Medical Community, and increasing the rate of inside county visits for inpatients.

Enhancing identification and treatment of patients with concomitant chronic venous insufficiency and diabetes mellitus. A modified Delphi study from the CODAC (ChrOnic venous disease and Diabetes Advisory Council) group

BACKGROUND

Chronic venous insufficiency (CVI) and diabetes mellitus (DM) pose significant burdens to patients and healthcare systems. While the two diseases share a number of commonalities in risk factors and pathophysiology, they are often assessed and managed separately. This can lead to a worsening of comorbidities and limitations in a patient's quality of life. This project aims to develop recommendations to enhance the identification and treatment of patients with concomitant CVI and DM.

METHODS

Using a modified Delphi method, a panel of experts developed 38 Likert Scale and two multiple choice questions across six key themes. These were used to form an online survey which was disseminated through a convenience sampling approach to CVI and DM healthcare professionals across Europe, Central America, South America, and the Middle East. The threshold for consensus was set at ≥75%.

RESULTS

A total of 238 responses were received. 27/38 statements attained >90% agreement, nine of 38 attained between 75-90%, and two failed to meet the threshold (<75%). The awareness around the impact of the two diseases was high, but a gap was highlighted in the identification of patients with concomitant CVI and DM.

CONCLUSIONS

The high level of agreement shows that healthcare professionals are aware of the gaps in identification and treatment of patients with concomitant CVI and DM, and of the need to approach this as a combined therapy area. An algorithm is proposed to help the identification of at-risk patients and to provide recommendations on the management of patients with concomitant disease.

Prescription of oral antidiabetics in Mexico. A cross-sectional study

In 2016 diabetes was declared an epidemic and a health emergency in Mexico. As the rationale of the treatment is to achieve target glycemia levels, the appropriateness of the medications used is important. The aim of this study is to learn the pattern of antidiabetic drug prescription and factors associated with inappropriate prescription in Mexico. A retrospective cross-sectional drug utilization study has been conducted. A randomly selected sample was carefully examined. Out of 3600 clinical records of patients diagnosed with type 2 diabetes mellitus (T2DM), 196 records were revised. As far as control is concerned, 36.7% had their glycemia values in the recommended range. A combination of different antidiabetics was the most common pattern observed (60.7%); the most frequent was that of the association of metformin with whatever oral antidiabetics. Prescriptions were considered as inappropriate in 149 cases (76.0%); younger age and lack of nutritional assessment was significantly related to inappropriate prescription. A trend to use more drugs for treating T2DM has been consistently observed. Despite using so many drugs, most of the patients are not controlled. Avoiding inappropriate prescription by following current guidelines may contribute to a better control and, in turn, decrease morbidity and mortality for this cause.

The Trend in the Prevalence of Diabetes Mellitus in the Mexican Indigenous Population From 2000 to 2018

Introduction

Diabetes is a worldwide public health problem. In Mexico, diabetes was the third leading cause of death in the total population in 2020. The indigenous people in Mexico are approximately 6%. This study aims to estimate the trends in diabetes prevalence from 2000 to 2018 in the group of Mexican indigenous language speakers and to analyze the main sociodemographic (e.g., age, educational and socioeconomic level, and the urbanicity of the area of residence) and clinical (e.g., age of diabetes onset, years with diabetes, and BMI) characteristics of this group.

Methods

This cross-sectional study included participants aged ≥20 years from 4 National Health Surveys, 2000-2018. We presented the analyses for indigenous and nonindigenous strata. Logistic models adjusted were used to estimate the trend of diabetes in the study period.

Results

We found a significant increase in the prevalence of diabetes in the indigenous group. This trend in the ORs was maintained when adjusting for age, sex, waist circumference, and area of residence. For the study period, the prevalence change in diagnosed diabetes in the indigenous group was greater than that in the nonindigenous group (OR=6.4, 95% CI=4.1, 8.8 and OR=3.3, 95% CI=2.5, 4.1, respectively). We also found a significant prevalence change in undiagnosed diabetes for the indigenous group (OR=7.7, 95% CI=1.3, 14.6).

Conclusions

In contrast to the results in nonindigenous populations, our main result reveals an increasing probability of being diabetic in the indigenous population from 2006 to 2018. It is necessary to clarify the origin of the accelerated change in diabetes prevalence among the indigenous population in Mexico.

Hospitalized COVID-19 patients with diabetes have an increased risk for pneumonia, intensive care unit requirement, intubation, and death: A cross-sectional cohort study in Mexico in 2020

Background

Diabetes mellitus is a chronic health condition that has been linked with an increased risk of severe illness and mortality from COVID-19. In Mexico, the impact of diabetes on COVID-19 outcomes in hospitalized patients has not been fully quantified. Understanding the increased risk posed by diabetes in this patient population can help healthcare providers better allocate resources and improve patient outcomes.

Objective

The objective of this study was to quantify the extent outcomes (pneumonia, intensive care unit [ICU] stay, intubation, and death) are worsened in diabetic patients with COVID-19.

Methods

Between April 14, 2020 and December 20, 2020 (last accessed), data from the open-source COVID-19 database maintained by the Mexican Federal Government were examined. Utilizing hospitalized COVID-19 patients with complete outcome data, a retrospective cohort study (N = 402,388) was carried out. In relation to COVID-19, both univariate and multivariate logistic regression were used to investigate the effect of diabetes on specific outcomes.

Results

The analysis included 402,388 adults (age >18) with confirmed hospitalized COVID-19 cases with mean age 46.16 (standard deviation = 15.55), 214,161 (53%) male. The outcomes delineated included pneumonia (N = 88,064; 22%), ICU requirement (N = 23,670; 6%), intubation (N = 23,670; 6%), and death (N = 55,356; 14%). After controlling for confounding variables diabetes continued to be an independent risk factor for both pneumonia (odds ratio [OR]: 1.8, confidence interval [CI]: 1.76-1.84, p < 0.01), ICU requirement (OR: 1.09, CI: 1.04-1.14, p < 0.01), intubation (OR: 1.07, CI: 1.04-1.11, p < 0.01), and death (OR: 1.88, CI: 1.84-1.93, p < 0.01) in COVID-19 patients.

Conclusions

According to the study, all outcomes (pneumonia, ICU requirement, intubation, and death) were greater among hospitalized individuals with diabetes and COVID-19. Additional study is required to acquire a better understanding of how diabetes affects COVID-19 outcomes and to develop practical mitigation techniques for the risk of severe sickness and complications in this particular patient population.

A comparison of rural-urban differences in out-of-pocket expenses among older Mexicans with diabetes

Objective

To compare total out-of-pocket expenses for physician visits and medications among older adults living with diabetes in Mexico from urban, semi-urban, and rural areas.

Methods

The sample included 2,398 Mexicans aged 65 years and older with self-reported diabetes from the 2018 Mexican Health and Aging Study. Out-of-pocket expenses for physician visits and medications were regressed on locality, controlling for several factors.

Results

The profile of those with higher out-of-pocket medication expenditures included rural localities, higher education, unmarried, depressive symptoms, participation in Seguro Popular, and lacking insurance. In the multivariate analysis, rural older adults with diabetes paid a higher amount in medication expenditures compared with other localities.

Conclusion

Differences in locality are closely tied to the effective implementation of Seguro Popular. Although this program has improved access to care, participants have higher out-of-pocket expenditures for medications than those on employer-based plans across all localities. Among all groups, the uninsured bare the highest burden of expenditures, highlighting a continued need to address health inequities for the most underserved populations.

The societal impact of early intensified treatment in patients with type 2 diabetes mellitus

Aim: The current study estimates the societal impact of early intensified treatment compared with initial monotherapy with subsequent treatment intensification in newly diagnosed adults with type 2 diabetes mellitus in Mexico. Methods: An individual patient-level simulation and a static cohort model were employed to simulate the treatment pathway and the probability of experiencing complications of diabetes. The avoided number of events was translated into avoided productivity losses, which were monetized using wages. Results: Patients on early intensified treatment experienced approximately 13,000 fewer complication events over 10 years. This was translated into a societal impact of $54 million (USD). Conclusion: Early treatment intensification is likely to be of particular benefit to health outcomes and productivity losses.

Comparison of Diabetes Mellitus Risk Factors in Mexico in 2003 and 2014

Objective

The prevalence of diabetes mellitus in Mexico is very high. This study aimed to compare the risk factors of diabetes mellitus in Mexican adults in 2003 and in 2014.

Methods

This study had a repeated cross-sectional design. Data from the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) from Mexico (Wave 0, 2003, and Wave 2, 2014) were compared. Self-reported diabetes mellitus (outcome) was evaluated with the yes/no question: "Have you ever been diagnosed with diabetes mellitus (high blood sugar)?" Bivariate analyses and multivariable logistic regression analyses adjusted for potential risk factors were conducted.

Results

In 11 years (2003-2014), the prevalence of self-reported diabetes mellitus in Mexican adults increased by 2.6 times in those younger than 50 years (2003: 2.1%; 2014: 5.5%) and by 1.9 times in those ≥50 years (2003: 12.7%; 2014: 24.2%). In 2003, the risk factors associated with diabetes mellitus were female sex (OR 1.344, 95% CI 1.176-1.536), age ≥50 years (OR 6.734, 95% CI 5.843-7.760), being overweight (OR 1.359, 95% CI 1.175-1.571), obesity (OR 1.871, 95% CI 1.583-2.211), and lower physical activity of <600 MET-minutes/week (OR 1.349, 95% CI 1.117-1.630). In 2014, the exposure characteristics significantly associated with diabetes mellitus were female sex (OR 1.244, 95% CI 1.025-1.511), older age ≥50 years (OR 4.608, 95% CI 3.260-6.515), being overweight (OR 1.649, 95% CI 1.305-2.083), obesity (OR 1.778, 95% CI 1.398-2.261), and in those who had not attended/completed primary school (OR 1.360, 95% CI 1.042-1.773).

Conclusion

The prevalence of diabetes mellitus in Mexico significantly increased from 2003 to 2014. Female sex, age older than 50 years, and being overweight or obese were significant risk factors in both 2003 and 2014. Not having completed primary school was a new significant risk factor in 2014. Public health policies and strategies should prioritize decreasing the high levels of overweight and obesity, and improve health literacy in Mexico.

Understanding of front of package nutrition labels: Guideline daily amount and warning labels in Mexicans with non-communicable diseases

One strategy for the prevention and treatment of non-communicable diseases (NCDs) is the implementation of the front-of-pack labeling (FoPL) in foods and beverages. In 2020, Mexico adopted the warning label system (WL) as a new public health policy, whose aim is to help consumers make healthier food choices. Previously, the Guideline Daily Amount (GDA) was the labelling used it. This paper aims to compare the understanding of two FoPL, the GDA and the WL, through the identification of unhealthy products in Mexicans with NCDs. We analyzed data from 14,880 Mexican adults older than 20 years old with NCDs (overweight-obesity (OW/O), self-reported diabetes mellitus 2 (DM2), or/and hypertension (HT), or/and dyslipidemia (Dys)). Participants were randomly assigned to one of two groups: the GDA labeling or WL. Each group had to respond to a survey and had to classify food products images as healthy or unhealthy according to the labelling system to which they were assigned. The correct classification was determined according to the criteria of Chile’s labeling nutrient profile stage 3. To evaluate the correct classification in each one of the groups we evaluated the differences in proportions. Logistic regression models were used to assess the likelihood to correctly classify the product according to participants’ number of diseases and WL information, taking GDA label as a reference. Participants who used the information contained in the GDA label misclassified food product labels in greater proportion (70%), mostly participants with three or more NCDs (participants with OW/O+ HT+ Dys, represent 42.3% of this group); compared with those who used WL (50%). The odds of correct classification of food products using WL image were two times greater compared to GDA image in participants with NCDs; being greater in participants with three or more NCDs. The study results highlight the usefulness of WL as it helps Mexicans with NCDs to classify unhealthy food products more adequately compared with GDA.

Testing Scalability of a Diabetes Self-Management Intervention in Northern Mexico: An Ecological Approach

Background: Type 2 diabetes mellitus (T2DM) has become a major issue in Mexico, reporting almost 100,000 attributable deaths in 2016. Low-income Mexican citizens who face various issues associated with T2DM, including the lack of access to self-management services, are particularly affected by the condition. Health centers have been designated to serve T2DM patients by providing resources on chronic disease prevention. Meta Salud Diabetes (MSD) is a self-management intervention developed to address cardiovascular complications and other health issues within the T2DM population, which have been proven effective and useful for health centers. The intervention was designed for T2DM support groups—grupos de ayuda mutua (GAMs) located within health centers.

Methods: From February to June 2019, a binational research team conducted a test scale-up study in Northwest Sonora under the Ministry of Health utilizing the Institute for Healthcare Improvement Framework for scaling up health interventions. Investigators worked in collaboration and trained 19 stakeholders from a regional health system identified from various ecological levels on MSD and implementation process.

Results: All five GAMs within the regional health system received and completed the intervention. In total, 72 participants were enrolled with behavioral and biological [HbA1c, blood pressure, body mass index (BMI)] measures taken at baseline. Post-intervention measurements were taken from 72% of participants who completed the intervention. Statistical analysis demonstrated improved behavioral and biological measures when comparing baseline to post-intervention, specifically statistically significant improvements in HbA1c and sugar-sweetened beverage consumption. Implementation fidelity (IF) measures indicated extensive adherence to the intervention curriculum, and moderators specifically demonstrated influences on implementation. Stakeholders from various ecological levels provided support to those facilitating the MSD intervention by allotting time and resources to properly prepare for sessions. An implementation coordinator from the regional health office assisted MSD facilitators by resolving barriers to implementation and worked toward federal accreditation for GAMs to receive additional funding.

Conclusion: Results provide evidence for using regional health systems as a scalable unit when implementing chronic disease self-management interventions state- and nationwide. This study will help inform future efforts to scale up the health intervention in various states throughout Mexico.

Screening Diabetic Retinopathy Using an Automated Retinal Image Analysis System in Independent and Assistive Use Cases in Mexico: Randomized Controlled Trial

BACKGROUND

The automated screening of patients at risk of developing diabetic retinopathy represents an opportunity to improve their midterm outcome and lower the public expenditure associated with direct and indirect costs of common sight-threatening complications of diabetes.

OBJECTIVE

This study aimed to develop and evaluate the performance of an automated deep learning-based system to classify retinal fundus images as referable and nonreferable diabetic retinopathy cases, from international and Mexican patients. In particular, we aimed to evaluate the performance of the automated retina image analysis (ARIA) system under an independent scheme (ie, only ARIA screening) and 2 assistive schemes (ie, hybrid ARIA plus ophthalmologist screening), using a web-based platform for remote image analysis to determine and compare the sensibility and specificity of the 3 schemes.

METHODS

A randomized controlled experiment was performed where 17 ophthalmologists were asked to classify a series of retinal fundus images under 3 different conditions. The conditions were to (1) screen the fundus image by themselves (solo); (2) screen the fundus image after exposure to the retina image classification of the ARIA system (ARIA answer); and (3) screen the fundus image after exposure to the classification of the ARIA system, as well as its level of confidence and an attention map highlighting the most important areas of interest in the image according to the ARIA system (ARIA explanation). The ophthalmologists' classification in each condition and the result from the ARIA system were compared against a gold standard generated by consulting and aggregating the opinion of 3 retina specialists for each fundus image.

RESULTS

The ARIA system was able to classify referable vs nonreferable cases with an area under the receiver operating characteristic curve of 98%, a sensitivity of 95.1%, and a specificity of 91.5% for international patient cases. There was an area under the receiver operating characteristic curve of 98.3%, a sensitivity of 95.2%, and a specificity of 90% for Mexican patient cases. The ARIA system performance was more successful than the average performance of the 17 ophthalmologists enrolled in the study. Additionally, the results suggest that the ARIA system can be useful as an assistive tool, as sensitivity was significantly higher in the experimental condition where ophthalmologists were exposed to the ARIA system's answer prior to their own classification (93.3%), compared with the sensitivity of the condition where participants assessed the images independently (87.3%; P=.05).

CONCLUSIONS

These results demonstrate that both independent and assistive use cases of the ARIA system present, for Latin American countries such as Mexico, a substantial opportunity toward expanding the monitoring capacity for the early detection of diabetes-related blindness.

Regional and state-level patterns of type 2 diabetes prevalence in Mexico over the last three decades

AIMS

We aimed to characterize and illustrate the regional and state-level change in type 2 diabetes (T2D) prevalence in Mexico between 1990 and 2017.

METHODS

We conducted an ecological and secondary analysis using data from the Global Burden of Disease study on T2D prevalence of the adult Mexican population. We estimated the absolute increase and annual growth rate of T2D prevalence between 1990 and 2017, stratified by age group and region.

RESULTS

Nationally, between 1990 and 2017, the prevalence of T2D in Mexico increased from 9.5% to 14.3%. The highest increase in T2D prevalence was observed in the East and Southcentral regions, with the lowest absolute change in T2D prevalence observed in Northern states. The highest average annual growth rate in T2D prevalence was observed in Southern Mexico, in the three Southern states with the lowest human development index, and among individuals ages 15-49 years across all regions, compared to those 50 years and older.

CONCLUSIONS

The prevalence of T2D in Mexico has increased substantially over the past three decades, with a clear shift in T2D prevalence from Northern to Southern states and a faster increase occurring in Southern Mexico among younger adults and in areas with lower economic resources.

Economic evaluation of a novel community-based diabetes care model in rural Mexico: a cost and cost-effectiveness study

OBJECTIVES

Diabetes is the leading cause of disability-adjusted life years in Mexico, and cost-effective care models are needed to address the epidemic. We sought to evaluate the cost and cost-effectiveness of a novel community-based model of diabetes care in rural Mexico, compared with usual care.

DESIGN

We performed time-driven activity-based costing to estimate annualised costs associated with typical diabetes care in Chiapas, Mexico, as well as a novel diabetes care model known as Compañeros En Salud Programa de Enfermedades Crónicas (CESPEC). We conducted Markov chain analysis to estimate the cost-effectiveness of CESPEC compared with usual care from a societal perspective. We used patient outcomes from CESPEC in 2016, as well as secondary data from existing literature.

SETTING

Rural primary care clinics in Chiapas, Mexico.

PARTICIPANTS

Adults with diabetes.

INTERVENTIONS

CESPEC is a novel, comprehensive, diabetes care model that integrates community health workers, provider education, supply chain management and active case finding.

OUTCOME MEASURE

The primary outcome was the incremental cost-effectiveness of CESPEC compared with care as usual, per quality-adjusted life year (QALY) gained, expressed in 2016 US dollars.

RESULTS

The economic cost of the CESPEC diabetes model was US$144 per patient per year, compared with US$125 for diabetes care as usual. However, CESPEC care was associated with 0.13 additional years of health-adjusted life expectancy compared with usual care and 0.02 additional years in the first 5 years of treatment. This translated to an incremental cost-effectiveness ratio (ICER) of US$2981 per QALY gained over a patient's lifetime and an ICER of US$10 444 over the first 5 years. Findings were robust to multiple sensitivity analyses.

CONCLUSIONS

CESPEC is a cost-effective, community-based model of diabetes care for patients in rural Mexico. Given the high prevalence and significant morbidity associated with diabetes in Mexico and other countries in Central America, this model should be considered for broader scale up and evaluation.

Comparison of Clinical Tests for Peripheral Diabetic Neuropathy in a Type 1 Diabetes Cohort

OBJECTIVE

To examine the performance and agreement of 5 modalities for testing sensory neuropathy against a neurothesiometer among Hispanic patients with type 1 diabetes (T1D) in an outpatient setting.

METHODS

A cross-sectional study was conducted at a tertiary reference center in Mexico City. Sensitivity, specificity, predictive values, and likelihood ratios were calculated using a VibraTip device, 128 Hz tuning fork, and the Semmes-Weinstein 5.07/10 g monofilament test, Ipswich touch test (IpTT), and pinprick test (PPT). The VPT obtained using a neurothesiometer was used as the standard. Agreement between tests was calculated using kappa coefficients.

RESULTS

Our study included 78 patients (156 examinations), of whom 56.4% were females. The mean age was 38.2 ± 13.0 years, and the mean body mass index was 24.6 ± 4.8 kg/m². The best sensitivity was found for IpTT and VibraTip (89.7% and 79.3%, respectively), while the PPT and IpTT had the highest positive predictive values (94.4% and 92.9%, respectively). The highest kappa coefficients were obtained for the IpTT vs neurothesiometer (kappa coefficient [κ] = 0.893, P < .001), followed by VibraTip vs neurothesiometer (κ = 0.782, P < .001). The VibraTip vs IpTT also had a substantial agreement (κ= 0.713, P < .001).

CONCLUSION

Our findings demonstrated that the IpTT had the best diagnostic performance and agreement compared with the standard in this cohort of Hispanic patients with T1D. The IpTT is a useful, simple test for diabetic neuropathy screening. These findings support its inclusion in future guidelines for diabetic foot examination.

Comparison of prevalence of diabetes complications in Brazilian and Mexican adults: a cross-sectional study

BACKGROUND

Type 2 diabetes is more frequent in Latin American people than in non-Hispanic whites due to a combination of genetic and lifestyle risk factors. Brazil and Mexico are the most populous countries in Latin America. The present study aimed to compare the results of the National Health Survey "PNS" in Brazil and the National Survey Health and Nutrition "ENSANUT" in Mexico regarding the prevalence, complications and healthcare issues of diabetes in both countries.

METHODS

A cross-sectional study was conducted with data from the National Health Survey (PNS) of 2013 in Brazil and the National Survey of Health and Nutrition (ENSANUT) of 2018 in Mexico. The prevalence of diabetes, complications and risk factors related to developing diabetes were considered.

RESULTS

The respondents included 3636 individuals in Brazil and 4555 individuals in Mexico. There were significant differences in age and time living with diabetes between the two countries. Mexican people had twice as likely as Brazilian people to have a complication (p < 0.0001). The principal risk factor (OR 2.47; p ≤ 0.0001) for developing any diabetic complication was living with diabetes for more than 15 years. Visual impairment was the most frequent complication in both countries, but it was more prevalent in Mexico (p ≤ 0.001).

CONCLUSIONS

Diabetes complications are important health problems in Brazil and Mexico. Visual impairment was the principal complication in both countries. Several factors, such as access to and type of health system, living in a rural area, treatment, BMI and performing preventive actions, affected the risk of developing a complication. However, living with diabetes for more than 15 years was the principal risk factor. National health surveys have added significant information on the impact of diabetes in these Latin American populations. This comparison of data could provide valuable information to guide national policies and program decisions in both countries.

Incremental Risk of Developing Severe COVID-19 Among Mexican Patients With Diabetes Attributed to Social and Health Care Access Disadvantages

OBJECTIVE

Diabetes is an important risk factor for severe coronavirus disease 2019 (COVID-19), but little is known about the marginal effect of additional risk factors for severe COVID-19 among individuals with diabetes. We tested the hypothesis that sociodemographic, access to health care, and presentation to care characteristics among individuals with diabetes in Mexico confer an additional risk of hospitalization with COVID-19.

RESEARCH DESIGN AND METHODS

We conducted a cross-sectional study using public data from the General Directorate of Epidemiology of the Mexican Ministry of Health. We included individuals with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 between 1 March and 31 July 2020. The primary outcome was the predicted probability of hospitalization, inclusive of 8.5% of patients who required intensive care unit admission.

RESULTS

Among 373,963 adults with COVID-19, 16.1% (95% CI 16.0-16.3) self-reported diabetes. The predicted probability of hospitalization was 38.4% (37.6-39.2) for patients with diabetes only and 42.9% (42.2-43.7) for patients with diabetes and one or more comorbidities (obesity, hypertension, cardiovascular disease, and chronic kidney disease). High municipality-level of social deprivation and low state-level health care resources were associated with a 9.5% (6.3-12.7) and 17.5% (14.5-20.4) increased probability of hospitalization among patients with diabetes, respectively. In age-, sex-, and comorbidity-adjusted models, living in a context of high social vulnerability and low health care resources was associated with the highest predicted probability of hospitalization.

CONCLUSIONS

Social vulnerability contributes considerably to the probability of hospitalization among individuals with COVID-19 and diabetes with associated comorbidities. These findings can inform mitigation strategies for populations at the highest risk of severe COVID-19.

Use of an electronic integral monitoring system for patients with diabetes to identify factors associated with an adequate glycemic goal and to measure quality of care

AIMS

To evaluate the use of the electronic integral monitoring system (SMID) to identify factors associated to glycemic control and its impact in the quality of care in patients with type 2 diabetes (T2D).

METHODS

T2D patients registered in SMID were analyzed. Biochemical, clinical and lifestyle variables were recorded. Factors associated to HbA1c ≤7% were explored. Quality of care of the clinic was measured according to the National Committee for Quality Assurance Criteria (NCQA) that requires a score of 75 to achieve a good quality of care.

RESULTS

511 patients were included. Prescription of basal insulin, SGLT-2 inhibitors and barriers to follow nutritional plan were associated with decreased probability of having adequate glycemic control. Patients in the maintenance stage of motivation had higher probability of having HbA1c ≤7%. According to NCQA evaluation 60 points were achieved. Glucose goals were not met; 35.9% had HbA1c ≥9% and 17% HbA1c <7%. While foot evaluation, smoking approach, blood pressure and lipids goals were accomplished; eye and renal evaluations were borderline.

CONCLUSION

Glycemic control in patients with long standing T2D and multiple comorbidities is challenging, which directly impacts in the quality of care. Professionals should focus in reinforcing non-pharmacological interventions to optimize glycemic targets.

A High Incidence of Metabolic Syndrome Traits in Mexicans Points at Obesity-Related Metabolic Dysfunction

INTRODUCTION

Metabolic Syndrome (MS) is a construct relating to a series of metabolic dysfunctions attributable to insulin resistance and obesity. Here, we estimate the incidence of MS according to their individual components using a Mexican open-population cohort.

METHODS

We evaluated data of 6144 Mexicans amongst whom 3340 did not have MS either by IDF or ATP-III definitions using data from an open-population cohort. We estimated the incidence of MS and each of its traits after a median follow-up of 2.24 (IQR 2.05-2.58) years and evaluated risk factors for MS incidence and each of its traits. We also explored individuals without any MS trait to evaluate trait and MS incidence after follow-up.

RESULTS

We observed a high incidence of MS-IDF (115.11 cases per 1000 person-years, 95% CI 107.76-122.47), followed by MS-ATP-III (75.77 cases per 1000 person-years, 95% CI). The MS traits with the highest incidence were low HDL-C and abdominal obesity, which was consistent for subjects without MS and those without any MS trait. When assessing predictors of MS incidence, obesity, insulin resistance, and increased apolipoprotein B levels predicted MS incidence. Weight loss >5% of body weight and physical activity were the main protective factors. Obesity was a main determinant for incident MS traits in our population, with weight loss being also a protective factor for most MS traits.

CONCLUSION

We observed a high incidence of MS in apparently healthy Mexican adults. Low HDL-C and abdominal obesity were the most frequent incident MS traits, with obesity being the main determinant of its incidence.

'If I don't take care of myself, who will?' Self-caring subjects in Oaxaca's mutual-aid groups

Based on seven months of ethnographic fieldwork in two urban health centres in Oaxaca City, Mexico, this paper analyses the ways in which underprivileged middle-aged and older female patients experience and transform grupos de ayuda mutua (GAMs), or mutual-aid groups, a public health programme aimed at improving chronic patients' adherence to their biomedical treatments. GAMs work as 'technologies of the self' within the context of the Mexican neoliberal regime and patients are urged to be self-responsible. GAM members regard such urging favourably and act according to their broader understandings of life, which they see as a lucha (struggle) that requires cuidarse (a polysemic verb alluding to self-care for self-preservation) and hard work in a structurally unequal place characterised by precarity and social unrest. This seemingly rugged individualism is converted into microlevel collaboration through culturally distinctive Oaxacan practices of mutual help. By exploring the playful ways these women participate in GAMs, this paper shows how biomedical settings can be repurposed as spaces of socialisation and wellbeing for older women living in vulnerable conditions.

Deadly Companions: COVID-19 and Diabetes in Mexico

In this commentary, I assess the adverse syndemic interactions between COVID-19 and diabetes mellitus. This syndemic is of major concern for a country like Mexico which has seen a steady rise in the percentage of its population suffering these diseases. Mexico now has one of the highest rates of diabetes in the world and a rapidly growing COVID-19 caseload.

How dietary transition changed land use in Mexico

The nutrition transition towards western diets in developing countries occurs at multiple levels, impacting health and society and also the environment. In Mexico, the shift in food consumption and production patterns, particularly in relation to animal source foods (ASF), has changed land use. We studied the consumption and production of ASF and change in agricultural land use in Mexico during the second half of the twentieth century and until 2013; using domestic and international data sources, our findings show an increasing proportion of farmed area devoted to the production of feed crops domestically, and also an increasing demand of farmed feed beyond national borders. We discuss how the intensification of livestock production is associated to major environmental threats and suggest that opportunities are available for sustainable and healthy food options.

Prevalence and Risk Factors for Self-Report Diabetes Mellitus: A Population-Based Study

The aim of this study was to estimate the prevalence and risk factors for self-reported diabetes mellitus (DM) in the adult population of the Central-West region of Brazil. In 2013, a cross-sectional study using the data from the National Health Survey and comprising 7519 individuals aged ≥18 years from the Central-West region was conducted. Participants were interviewed at their homes about sociodemographic data and risk factors for DM. To verify the risk factors with DM, the Poisson regression model was used. The analyses were performed for the total sample and stratified according to sex. The prevalence of DM was 6.5% (95% confidence interval [95% CI], 5.7–7.3). The diagnosis of self-reported DM was 4.3% in men and 7.5% in women. In the global sample, it was found that age between 40–59 years and ≥60 years, previous smoking (former smoker), self-reported hypertension, self-reported dyslipidemia, overweight, and obesity were independently associated with self-reported DM. In men, risk factors were: Age ≥ 60 years, self-reported hypertension, self-reported dyslipidemia, and obesity. In women, risk factors were: Age 30–39 years, 40–59 years, and ≥60 years, previous smoking (former smoker), self-reported hypertension, self-reported dyslipidemia, overweight, and obesity. Conclusion: The prevalence of DM was 6.5%. DM was associated with advanced age; previous smoking (former smoker), hypertension, dyslipidemia, overweight, and obesity. Some differences in risk factors between men and women were noted.

Peer Support Added to Diabetes Education Improves Metabolic Control and Quality of Life in Mayan Adults Living With Type 2 Diabetes: A Randomized Controlled Trial

BACKGROUND

Yucatán, located in the southern region of Mexico, is the state with the country's highest prevalence of uncontrolled diabetes. Because of its particular cultural and socioeconomic characteristics, the residents of Yucatán face unique health-care challenges. The objective of our study was to evaluate the effect of peer support added to a diabetes education program on glycemic control and diabetes-related quality of life when compared with a conventional diabetes education program in patients with type 2 diabetes in a Mayan community in Mexico.

METHODS

In March 2015, a total of 58 participants with a previous diagnosis of type 2 diabetes who were recruited from community health centres in Komchén were randomly assigned in equal numbers to 1 of 2 groups: 1) a peer support and diabetes self-management education group (PSEG) or 2) a conventional diabetes self-management education-only group. The primary outcomes of interest were glycated hemoglobin (A1C) values and diabetes-related quality of life. The majority of subjects were bilingual (Mayan and Spanish speakers), female and middle aged, and had a low level of formal education and high baseline A1C (mean, 8.7%).

RESULTS

Whereas both groups showed significant improvements from baseline to study end in absolute levels of A1C, the PSEG group had a more pronounced clinical improvement, but no statistical improvement, in A1C compared with the conventional diabetes self-management education-only group. PSEG participants exhibited statistically significant improvement in diabetes-related quality of life at 8 months.

CONCLUSIONS

Our study demonstrates the benefits of peer-support education above and beyond the impact of diabetes self-management education on diabetes-related quality of life in an underserved Mayan community in Mexico.

¡Sí, Yo Puedo Vivir Sano con Diabetes! A Self-Management Randomized Controlled Pilot Trial for Low-Income Adults with Type 2 Diabetes in Mexico City

BACKGROUND

Type 2 diabetes (T2D) is a worldwide epidemic and a leading cause of death in Mexico, with a prevalence of 15.9%, and >70% of diagnosed adults have poor glycemic control [glycated hemoglobin (HbA1c) >7.5%]. We developed a diabetes self-management education program contextualized to the study population, including dietary preferences, health literacy, and health system.

OBJECTIVES

We aimed to evaluate the efficacy of a self-management + text message program (¡Sí, Yo Puedo Vivir Sano con Diabetes!) on primary (HbA1c), and secondary behavioral (self-management), clinical, and psychosocial outcomes in adults with T2D in Mexico City.

METHODS

Participants were recruited at public primary healthcare centers (Seguro Popular), and randomly allocated to treatment (n = 26) or wait-list control groups (n = 21) with data collected at 3 and 6 mo. The program included 7 weekly sessions and 6 mo of daily text/picture messages. Descriptive statistics and a generalized linear mixed model with intent-to-treat analysis were calculated.

RESULTS

Participants were 55.5 ± 8.8 y of age (mean ± SD), 68% female, 88.6% overweight/obese, and 57% lived in food-insecure households. Mean ± SD T2D duration was 11.9 ± 7.8 y and HbA1c was 9.2% ± 1.5%. There was 89% attendance at sessions and 6.4% attrition across both groups at 6 mo. Group-by-time effects were seen in self-monitoring of blood glucose (P < 0.01) and diabetes self-efficacy (P < 0.04); and a trend for lower HbA1c was seen in the intervention group at 6 mo (P = 0.11). Significant improvements in dietary behavior (P < 0.01) were demonstrated in the intervention group over time, but this did not reach statistical significance compared with the control group.

CONCLUSIONS

The program was associated with clinically significant improvements in T2D self-management, self-efficacy, and HbA1c over time. Thus, T2D self-management skills, including diet, were improved in a vulnerable metropolitan population.This trial was registered at clinicaltrials.gov as NCT03159299.

Effects of Cacao By-Products and a Modest Weight Loss Intervention on the Concentration of Serum Triglycerides in Overweight Subjects: Proof of Concept

Therapeutic approaches to decrease serum triglyceride (TG) concentrations are not successful mainly due to poor adherence or adverse effects of therapies. In consequence, the search for new low-cost and safer therapeutic alternatives is mandatory. Dark chocolate and cacao have shown promising results improving lipid profiles. Recently, using cacao by-products to reduce elevated cardiometabolic risk markers in an animal model of obesity induced by a high-fat diet and fructose, we showed that TGs, low-density lipoprotein cholesterol, and the TG/high-density lipoprotein (HDL) ratio decreased, suggesting that cacao by-products improved the metabolic function of obese animals. Based on these results, as a proof of concept, a blinded placebo-controlled study was implemented to explore the effects of cacao by-products on anthropometric and biochemical variables in a group of overweight subjects participating in a program composed of reduced-calorie-diet counseling plus a simple aerobic exercise plan. The results showed that counseling induced weight and abdominal circumference reductions in both groups. TGs did not change in the control group; however, TG decreased significantly by 54.9 mg/dL (27.9%) in the experimental group. The TG/HDL cholesterol ratio changed markedly (1.5) in the experimental group. The results reported suggest the use of cacao by-products as an alternative for the treatment of hypertriglyceridemia.

Risk of developing pre-diabetes or diabetes over time in a cohort of Mexican health workers

AIM

To determine the association between known risk factors (e.g., obesity, metabolic syndrome and its components) and the development of pre-diabetes or diabetes over time in a cohort of Mexican health workers.

METHODS

Participants in the Mexican Health Worker Cohort Study with complete information at two waves of data collection, 2004-2006 (W1) and 2011-2013 (W2), were included in the analysis (n = 1,174). Multivariable binary and multinomial logistic regression were used to examine the cross-sectional associations between specific risk factors and diabetes status (diabetes, pre-diabetes, or neither) at W1 and the longitudinal associations between changes in risk factors and progression of diabetes status from W1 to W2, respectively.

RESULTS

Mean time between waves was 7.0 years (SD 1.1). Prevalence of pre-diabetes and diabetes was 16% and 10% at W1 and increased to 30% and 16% at W2, respectively. The cross-sectional prevalence of pre-diabetes and diabetes was significantly higher among men, participants over the age of 45 years, and individuals who were overweight or obese or had metabolic syndrome (MS), three or more components of the MS, elevated alanine aminotransferase (ALT) levels, or elevated uric acid. In longitudinal analyses, remaining obese or gaining weight between waves was associated with an increased risk of developing pre-diabetes. A greater risk of developing pre-diabetes or diabetes was also observed among individuals who either maintained or acquired MS, elevated ALT, or elevated uric acid (only for diabetes) from W1 to W2.

CONCLUSIONS

Weight gain and acquiring or maintaining MS, elevated ALT levels, or elevated uric acid were associated with a significant risk of developing pre-diabetes or diabetes. Our findings, especially in the context of the obesity epidemic in Mexico, point towards an urgent need for initiatives to help reduce excess weight in order to avert future cases of pre-diabetes and diabetes.

Development of a diabetes self-management + mHealth program: tailoring the intervention for a pilot study in a low-income setting in Mexico

Background

Type 2 diabetes (T2D) is a public health pandemic disproportionately affecting low- and middle-income countries. The purpose of this formative research was to adapt evidence-based diabetes self-management education programs to the context of Seguro Popular clinics in Mexico. A theory-based mHealth (pictorial text messaging) component was developed.

Method

Our formative research and development of the program protocol consisted of six phases: (1) interviews and focus groups with stakeholders on the challenges to T2D management, curriculum content needs, and the use of mHealth as a supplement to a DSME program; (2) review of the theoretical underpinning, curriculum, and interactive strategies of four evidence-based DSME programs and modification to meet the needs of adults with T2D and systems of care in Mexico City; (3) development of theory-based illustrated text messages; (4) evaluation of text messaging acceptability and access in adults with T2D via focus groups; (5) development of program manual; and (6) development of a training program for health care providers.

Results

The ¡Sí, Yo Puedo Vivir Sano Con Diabetes! included 7 group-based weekly lessons; simple, interactive content; weekly empowerment messages; video novellas; group activities; and goal setting. Adaptations to the cultural context of Mexico included content/activities on diabetes etiology (addressing cultural misconceptions), nutrition (indigenous foods and plate method), self-blood glucose monitoring, and diabetes-related stress/coping. We used the Health Action Process Approach to guide the text message development, which posits that adoption, initiation, and maintenance of health behaviors require the development of intentions, plans, coping, and self-efficacy. Our final text message bank consisted of 181 messages. There were approximately 20–30 messages for each process of behavior change (e.g., action planning, maintenance self-efficacy) and 30 messages for each content topic (e.g., eating healthy, physical activity). There were 96 messages that were illustrated. Training materials were also developed.

Discussion

We used a systematic approach, collaboration with stakeholders, and a well-established behavior change theory to develop an evidence-based intervention to an international context and system of care. Collectively, this process has the potential to enhance the feasibility, acceptability, and efficacy of the program.

Progressive Shifts in the Gut Microbiome Reflect Prediabetes and Diabetes Development in a Treatment-Naive Mexican Cohort

Type 2 diabetes (T2D) is a global epidemic that affects more than 8% of the world's population and is a leading cause of death in Mexico. Diet and lifestyle are known to contribute to the onset of T2D. However, the role of the gut microbiome in T2D progression remains uncertain. Associations between microbiome composition and diabetes are confounded by medication use, diet, and obesity. Here we present data on a treatment-naive cohort of 405 Mexican individuals across varying stages of T2D severity. Associations between gut bacteria and more than 200 clinical variables revealed a defined set of bacterial genera that were consistent biomarkers of T2D prevalence and risk. Specifically, gradual increases in blood glucose levels, beta cell dysfunction, and the accumulation of measured T2D risk factors were correlated with the relative abundances of four bacterial genera. In a cohort of 25 individuals, T2D treatment-predominantly metformin-reliably returned the microbiome to the normoglycemic community state. Deep clinical characterization allowed us to broadly control for confounding variables, indicating that these microbiome patterns were independent of common T2D comorbidities, like obesity or cardiovascular disease. Our work provides the first solid evidence for a direct link between the gut microbiome and T2D in a critically high-risk population. In particular, we show that increased T2D risk is reflected in gradual changes in the gut microbiome. Whether or not these T2D-associated changes in the gut contribute to the etiology of T2D or its comorbidities remains to be seen.

The Meta Salud Diabetes Implementation Study: Qualitative Methods to Assess Integration of a Health Promotion Intervention Into Primary Care to Reduce CVD Risk Among an Underserved Population With Diabetes in Sonora, Mexico

Background: Within health promotion research, there is a need to assess strategies for integration and scale up in primary care settings. Hybrid interventions that combine clinical effectiveness trials with implementation studies can elicit important contextual information on facilitators and barriers to integration within a health care system. This article describes lessons learned in developing and implementing a qualitative study of a cluster-randomized controlled trial (RCT) to reduce cardiovascular disease (CVD) among people with diabetes in Sonora, Mexico, 2015–2019.

Methods:The research team worked cooperatively with health center personnel from 12 Centers that implemented the intervention. The study used observations, stakeholder meetings, case studies, staff interviews and decision maker interviews to explore issues such as staff capacity, authority, workflow, space, and conflicting priorities, as well as patients' response to the program within the clinical context and their immediate social environments. Applying a multi-layered contextual framework, two members of the research team coded an initial sample of the data to establish inclusion criteria for each contextual factor. The full team finalized definitions and identified sub nodes for the final codebook.

Results: Characteristics of management, staffing, and the local environment were identified as essential to integration and eventual adoption and scale up across the health system. Issues included absence of standardized training and capacity building in chronic disease and health promotion, inadequate medical supplies, a need for program monitoring and feedback, and lack of interdisciplinary support for center staff. Lack of institutional support stemming from a curative vs. preventive approach to care was a barrier for health promotion efforts. Evolving analysis, interpretation, and discussion resulted in modifications of flexible aspects of the intervention to realities of the health center environment.

Conclusion: This study illustrates that a robust and comprehensive qualitative study of contextual factors across a social ecological spectrum is critical to elucidating factors that will promote future adoption and scale up of health promotion programs in primary care. Application of conceptual frameworks and health behavior theory facilitates identification of facilitators and barriers across contexts.

Effectiveness of the Diabetes Prevention Program for Obesity Treatment in Real World Clinical Practice in a Middle-Income Country in Latin America

The Diabetes Prevention Program (DPP) is effective for the prevention of type 2 diabetes by weight loss with diet and physical activity. However, there is little evidence as to whether this program could be translated into real-world clinical practice in Latin American countries. The objective of this work was to evaluate the effectiveness of the DPP for the management of overweightness and obesity at 6 and 12 months in clinical practice in Mexico. This was a non-controlled intervention study implemented in five public clinics in northern Mexico. Two hundred and thirty-seven adults aged 45.7 ± 9.9 years with a Body Mass Index (BMI) of 34.4 ± 5.4 kg/m² received group sessions with an adaptation of the DPP, in addition to nutrition counseling. One hundred and thirty-three (56%) participants concluded the 6 month phase. They showed a significant weight loss, ranging from 2.76 ± 4.76 to 7.92 ± 6.85 kg (p ≤ 0.01) in the clinics. The intention-to-treat analysis showed a more conservative weight loss. Participant retention at the end of 12 months was low (40%). The implementation of the DPP in different public clinics in Mexico was effective in the management of obesity in the short term, but better strategies are required to improve participant retention in the long term.

Subgingival Microbiota of Mexicans with Type 2 Diabetes with Different Periodontal and Metabolic Conditions

BACKGROUND

Type-2-Diabetes (T2D) and Periodontitis are major inflammatory diseases. However, not much is known about the specific subgingival microbiota in Mexicans with diabetes and metabolic dysbiosis. The aim of this study was to describe the subgingival microbiota of Mexicans with T2D and the different periodontal and metabolic conditions, through "Checkerboard" DNA-DNA hybridization.

METHODS

Subjects were divided into two groups-periodontal-health (PH) (PH_non-T2D; n = 59, PH_T2D; n = 14) and generalized-periodontitis (GP) (GP_non-T2D; n = 67, GP_T2D; n = 38). Obesity (BMI ≥ 30 kg/m2) and serum levels of glycated-hemoglobin (HbA1c), total-lipids, triglycerides, total-cholesterol, high-density-lipids, and low-density-lipids were measured for the T2D individuals. Subgingival microbial identification was processed for 40 species through DNA-probes.

RESULTS

Subjects with T2D harbored significantly higher mean total levels (PH: p < 0.001, and GP_NS), a lower proportion of "red" complex (GP: p < 0.01), a higher proportion of "yellow" (GP; p < 0.001), and "orange" (GP; p < 0.01) complex than the non-T2D. GP_T2D individuals exhibited a greater proportion of putative-species-Campylobacter gracilis and S. constellatus (p < 0.001), and Parvimonas micra and Prevotella nigrescens (p < 0.01), than GP_non-T2D. T2D individuals with HbA1c > 8% had presented significantly higher mean pocket-depth and higher levels of G. morbillorum (p < 0.05) and those with obesity or dyslipidemia harbored higher levels, prevalence, or proportion of Streptococcus sp., Actinomyces sp., and Capnocytophaga sp.

CONCLUSIONS

T2D individuals harbored a particular microbial profile different to non-T2D microbiota. Metabolic control was related to dysbiosis of microbiota-HbA1c>8% related to periodontitis and obesity or dyslipidemia with the predominance of saccharolytic bacteria, irrespective of their periodontal condition.

Challenges to diabetes self-management for adults with type 2 diabetes in low-resource settings in Mexico City: a qualitative descriptive study

Background

The prevalence of type 2 diabetes (T2D) in Mexico is one of the highest in the world, with high morbidity and mortality, and difficulty meeting glycemic targets. The purpose of this study was to identify the challenges for T2D self-management as perceived by both adults with T2D and health care providers in primary health clinics from Seguro Popular in Mexico City.

Methods

This was a qualitative descriptive study conducted in three Seguro Popular primary care clinics in Mexico City using convenience sampling. Semi-structured interviews were conducted with participants and data were analyzed using a content analysis approach.

Results

The sample included 20 adults with T2D [52.5 years old (SD = 9.9), diagnosed with T2D for 12.3 years (SD = 6.3), mean A1C of 9.8% (SD = 2.4), 80% female, 90% with financial insecurity] and 19 providers [primarily female (78.9%), mean age of 41.6 years old (SD = 11.4), 12.3 mean years in practice (SD = 8.50)]. Personal challenges included cultural beliefs, lack of resources, challenges to lifestyle modification, lack of family support/competing demands, and mental health issues. System level challenges included lack of resources, perceived quality of care, and patient engagement barriers.

Conclusions

Evidence-based diabetes self-management programs need to become more accessible, taking into consideration the social determinants of health and building upon current initiatives to improve early diagnosis and treatment of T2D. Cultural beliefs, personal control, and low health literacy influence diabetes self-management in adults with T2D with limited resources. Mental health and financial challenges of adults with T2D will require multidisciplinary team-based care. Future research on best practices to implement and scale-up evidence-based patient-centered T2D prevention and DSME programs for the poor and underserved is warranted in Mexico and world-wide.

The impact of diabetes on labour market outcomes in Mexico: A panel data and biomarker analysis

Recent evidence for Mexico suggests important differences in health status between people with diagnosed and undiagnosed diabetes. However, there is at best scarce evidence on the economic consequences of diabetes, especially in contexts where the condition often remains undiagnosed, as is typically the case in low- and middle income countries. Using Mexican longitudinal and biomarker data we estimated the relationship between diabetes, as well as its time since diagnosis, and employment probabilities, wages and working hours. We further explored how these relationships differ for those with diagnosed and undiagnosed diabetes. For the longitudinal analyses, nationally representative data from 11995 men and 13858 women 15-64 years old were taken from three waves (2002, 2005, 2009) of the Mexican Family Life Survey. We estimated a fixed effects model to account for unmeasured time-invariant confounders of diabetes. We found a reduction in the probability of being employed of 7.7 and 6.3 percentage points for men and women, respectively, but no significant relationship with hours worked or wages. Employment probabilities fell gradually with each year since diagnosis for men but not for women. Using cross-sectional biomarker data, our results indicate that 68% of those exhibiting glycated hemoglobin (HbA1c) levels above the clinical diabetes threshold did not self-report a diagnosis, hence were undiagnosed. Nevertheless, regression analysis revealed that there was no association of diabetes with labour outcomes for undiagnosed women or men. This suggests that results based on self-reported diabetes cannot be extended to the (rather large) part of the population with undiagnosed diabetes, likely because of a selection of people in worse health and with a longer diabetes duration into the diagnosed population. Earlier diagnosis and improved treatment of diabetes therefore may prevent adverse health effects and related economic hardship.

VASCULAR COMPLICATIONS IN PATIENTS WITH TYPE 2 DIABETES: PREVALENCE AND COMORBIDITIES IN 6 COUNTRIES OF LATIN AMERICA (A COHORT OF THE DISCOVER STUDY PROGRAM)

Objective: To provide real world observational data about glucose control, the burden of diabetes, comorbidities, and cardiovascular risk factors among patients initiating second-line therapy in Latin America (LA). Methods: This report is a cross-sectional analysis of the LA cohort of the DISCOVER study, describing the regional prevalence of microvascular and macrovascular complications in Mexico, Costa Rica, Panama, Colombia, Argentina, and Brazil. Results: One thousand six hundred and sixteen patients were included in 69 investigational sites. Hemoglobin A1c was >7% (42 mmol/mol) in 81.3% of subjects. Macrovascular complications were reported by 13.8% of the subjects. Microvascular conditions were reported in 15.2% of the subjects. The prevalence of hypertension and of hyperlipidemia was 55.5% and 45.9%, respectively. Blood pressure, total cholesterol, and low-density lipoprotein were out of target levels in 38.5%, 51.2%, and 81.7% of the patients, respectively. Overweight or obesity was reported in 83.8% of the cases. Conclusion: Our study shows that patients with type 2 diabetes in LA are not reaching their glucose, lipids, blood pressure, and weight targets. The prevalence of microvascular (15.2%), macrovascular (13.8%), and uncontrolled comorbidities in patients at an early stage of the disease (initiating a second-line therapy) highlights the need for more aggressive risk factor screening as well as treatment in LA.

Diabetes Self-Management Behaviors, Health Care Access, and Health Perception in Mexico-US Border States

Purpose

The purpose of this study was to describe diabetes self-management behaviors, diabetes health care access, and health perception for Mexican adults and Hispanics residing in the Mexico-US border region.

Methods

This study used data from the Behavior Risk Factor Surveillance System (BRFSS) survey diabetes items (n = 26) to assess characteristics of Hispanics in 4 Arizona border counties (n = 216) and cross-sectional data from a modified BRFSS in a convenience sample of adults residing in Monterrey, Mexico (n = 351). Data were analyzed for descriptive statistics with SPSS.

Results

The Mexico cohort was younger than the Arizona cohort (59.36 [11.5] vs 65.54 [11.1], respectively) and the mean length of time with type 2 diabetes was similar. Less than 10% (9.7%) of the Arizona cohort reported never monitoring blood glucose compared to 22.5% of the Mexico cohort. The mean (SD) number of times in the past 12 months the Mexico cohort saw their health care provider was 9.09 (6.8) vs 4.49 (8.3) for the Arizona cohort. Despite provider access, there were differences in self-management behaviors between the cohorts.

Conclusions

Due to environmental and policy factors in the Mexico-US border region, there continues to be a gap in evidence-based practice and uptake of self-management behaviors for adults with diabetes. Resources such as the BRFSS and shared practice guidelines would bridge this gap.

Adequate health literacy is associated with better health outcomes in people with type 2 diabetes in Mexico

This study evaluates the health literacy of people with type 2 diabetes and its association with health outcomes. We conducted a cross-sectional survey in two family medicine clinics of the Mexican Institute of Social Security that included 778 diabetic patients >19 years of age. The Spanish version of the European Health Literacy questionnaire served to measure health literacy. Multiple logistic regressions were performed to determine the association between the independent variable (health literacy) and dependent variables (good self-rated health, glycemic control, and diabetes-related hospitalizations) after controlling for conceptually relevant patient's characteristics. Only 17.6% of patients had adequate health literacy; while, the remaining percentage showed inadequate (23%), or problematic (59.4%) health literacy. After adjusting for the patients' characteristics, those with adequate health literacy had 4.66 (95%CI: 2.26-9.61) times the odds of good self-rated health compared to those with inadequate literacy. Patients with adequate health literacy had 0.65 (95%CI: 0.49-0.86) times the odds of hospitalization due to diabetes compared to those with inadequate literacy. Compared to inadequate health literacy, problematic literacy was associated with increased odds of glycemic control. In conclusion, healthcare providers should actively address the health literacy needs of patients to increase good self-rated health, glucose control and reduce hospitalizations.

Demographics, A1C Testing, and Medication Use of Mexican Americans and Mexicans With Diabetes

Purpose

The purpose of this study is to investigate diabetes rates among Mexicans 20 years and older living in the United States and Mexico in 2012 and 2016.

Methods

The national sample was the National Health and Nutrition Examination Survey (NHANES) 2011-2012, NHANES 2015-2016, Mexican National Health and Nutrition Survey 2012 (ie, Encuesta Nacional de Salud y Nutrición 2012 [ENSANUT 2012]), and ENSANUT de Medio Camino 2016 (ENSANUT-MC 2016). Sex, age, A1C testing, and medication use (insulin, oral hypoglycemic agents, and both) were examined among participants.

Results

Most participants in study were female (50.7%, 53.9%, and 57.2%) and were younger (61 years, 57 years, and 60 years). A1C testing was conducted more in the United States (69.6% and 82.6%) than in Mexico (9.5% and 15.1%). More Mexicans (73.1% and 67.8% vs 54.9% and 54.9%) were using oral hypoglycemic agents, while more Mexican Americans used insulin (12.6% and 11.6% vs 6.3% and 11.1%) and used both insulin and oral hypoglycemic agents (17.1% and 15.8% vs 6.6% and 8.7%).

Conclusions

By examining and highlighting the diabetes mellitus practices and standardization of A1C testing, providers will be able to better understand and address the rising rates of diabetes in the United States and Mexico while driving practice and policy changes.

Preventive healthcare-seeking behavior among poor older adults in Mexico: the impact of Seguro Popular, 2000-2012

OBJECTIVE

Determine the effect of Seguro Popular (SP) on preventive care utilization among low-income SP beneficiaries and uninsured elders in Mexico.

MATERIALS AND METHODS

Fixed-effects instrumental-variable (FE-IV) pseudo-panel estimation from three rounds of the Mexican National Health and Nutrition Survey (2000, 2006 and 2012).

RESULTS

Our findings suggest that SP has no significant effect on the use of preventive services, including screening for diabetes, hypertension, breast cancer and cervical cancer, by adults aged 50 to 75 years.

CONCLUSIONS

Despite the evidence that suggests that SP has increased access to health insurance for the poor, inequalities in healthcare access and utilization still exist in Mexico. The Mexican government must keep working on extending health insurance coverage to vulnerable adults. Additional efforts to increase health care coverage and to support preventive care are needed to reduce persistent disparities in healthcare utilization.

De vuelta a la clínica: sin justificación no existe pregunta de investigación que valga

A clinical research question requires the concurrence of clinical experience and knowledge on methodology and statistics in that who formulates it. Initially, a research question should have a structure that clearly establishes what is that which is being sought (consequence or outcome), in whom (baseline status), and by action of what (maneuver). Subsequently, its reasoning must explore four aspects: feasibility and reasonableness of the questioning, lack of a prior answer, relevance of the answer to be obtained, and applicability. Once these aspects are satisfactorily covered, the question can be regarded as being "clinically relevant", which is different from being statistically significant, which refers to the probability of the result being driven by chance, which does not reflect the relevance of the question or the outcome. One should never forget that every maneuver entails adverse events that, when serious, discredit good results. It is imperative to have the possible answer estimated from within the structure of the question. The function of clinical research is to corroborate or reject a hypothesis, rather than to empirically test to find out what the outcome is.

Sex disparities in the epidemic of type 2 diabetes in Mexico: national and state level results based on the Global Burden of Disease Study, 1990-2017

PURPOSE

To analyze the type 2 diabetes (T2D) health burden in Mexico by sex at the national and state levels from 1990 to 2017.

METHODS

This was a secondary analysis based on data from the Global Burden of Disease Study, 1990-2017. We used the indicators of mortality rates, years of life lost due to premature mortality (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs).

RESULTS

At the national level, there was an increase in the standardized mortality rates, YLLs, YLDs and DALYs, especially in the male group. At the state level, the health impacts of T2D varied within the population and did not exhibit any clearly defined geographic pattern. However, the most pronounced increases in the various indicators occurred in the poorer states of the country.

CONCLUSION

T2D continues to have a dominant impact on Mexican public health, with marked disparities between the states. Working to reduce these health inequalities is necessary, and resources must be focused on the priority groups, for example, men, young and middle-aged adults, and individuals living in the states with the highest index of marginalization.

Political party ambitions and type-2 diabetes policy in Brazil and Mexico

In the Americas, next to the United States, Brazil and Mexico have the highest prevalence of type-2 diabetes. In contrast to most studies, this article compares and analyzes the politics behind the implementation of type-2 diabetes self-care management programs (DSM), which is a new area of scholarly research. This article claims that Brazil outpaced Mexico with respect to the implementation of effective DSM programs, the product of positive policy spillover effects associated with the president and governing political party's popular anti-poverty programs, and the enduring legacy of centralized ministry of health financial and human resource assistance to primary care programs in a context of decentralization. Brazil also benefited from having a strong partnership with international health agencies. None of these factors was present in Mexico. Findings suggest that more research needs to go into understanding the complex political and inter-governmental contexts facilitating DSM program implementation, which is a neglected area of research.
