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.

Background: Type 2 diabetes (T2D) is a public health pandemic disproportionately affecting low-and middleincome 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 selfefficacy. 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.

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.

The purpose of this study was to evaluate the preliminary efficacy of a self-management group + mHealth program (Yo Puedo!) on clinical (A1C, BP, BMI), self-management (diet, exercise, blood glucose monitoring), depressive symptom, and self-efficacy outcomes in adults with type 2 diabetes (T2D) at Seguro Popular clinics in Mexico City. Participants were randomly assigned to treatment (n=26) or wait-list control groups (n=21) with data collected at 3 and 6 months. The Yo Puedo! Program included 7 weekly sessions and 6 months of daily text messages. Descriptive statistics and generalized linear mixed model (GLMM) with random intercept were calculated. Adults with T2D were 55.5 years of age (±8.6), 68% female, 59% married/partnered, 88.6% overweight/obese, 50% lived in moderate/severe food insecure households, 35.7% had increased depressive symptoms, and 80% had A1C above 7.0%. Mean duration of T2D since diagnosis was 11.5 years (±7.1). There were no between-group differences on baseline characteristics. There was 89% attendance at sessions and 6% attrition at 6 months. Group by time effects were seen in blood glucose monitoring (p<.01), diabetes self-efficacy (p<.04); with a trend for lower A1C in the intervention group at 6 months (-1.76% in treatment group vs. -.97 in control group, p=.08). Time effects for the intervention group included improved diet, exercise, blood glucose monitoring, diabetes self-efficacy, depressive symptoms and A1C at 6 months (p<.05). Adults with T2D in Mexico City positively responded to the Yo Puedo! group + mHealth program with improvements in self-management, depressive symptoms, self-efficacy, and A1C. Empowering patients with T2D self-management skills can improve key behaviors, mental health and blood glucose outcomes in vulnerable populations. A fully powered clinical trial is warranted.
