Adequate care of type 2 diabetes is reflected by the individual’s adherence to dietary guidance; yet, few patients are engaged in diabetes self-care at the recommended level, regardless of race/ethnicity. Few studies on the effect of dietary medical advice on diabetes self-management (DSM) and glycemic control have been conducted on Haitian and African American adults with type 2 diabetes. These relationships were assessed in total of 254 Blacks with type 2 diabetes (Haitian Americans = 129; African Americans = 125) recruited from Miami-Dade and Broward Counties, Florida by community outreach methods. Although dietary advice received was not significantly different between the two Black ethnicities, given advice “to follow a diet” as a predictor of “using food groups” was significant for Haitian Americans, but not for African Americans. Haitian Americans who were advised to follow a diet were approximately 3 times more likely to sometimes or often use food groups (or exchange lists) in planning meals. Less than optimal glycemic control (A1C > 7.2) was inversely related to DSM for African Americans; but the relationship was not significant for Haitian Americans. A one unit increase in DSM score decreased the odds ratio point estimate of having less than optimal glycemic control (A1C > 7.2%) by a factor of 0.94 in African Americans. These results suggest that medical advice for diet plans may not be communicated effectively for DSM for some races/ethnicities. Research aimed at uncovering the enablers and barriers of diet management specific to Black ethnicities with type 2 diabetes is recommended.

Background: Metabolic outcomes of obesity and its associated disorders may not be equivalent across ethnicity and diabetes status. Aim: In this paper, we examined the association of abdominal obesity, by ethnicity and diabetes status, for indicators of glucose metabolism in Blacks. Methods: A cross sectional study was conducted in Haitian Americans (n= 186) and African Americans (n= 148) with and without type 2 diabetes mellitus (T2DM). Student’s t-test and Chi-squared test were used to assess differences in mean and proportion values between ethnicities with and without type 2 diabetes mellitus. Relationship between insulin resistance, ethnicity, diabetes status, abdominal obesity, and adiponectin levels were analyzed by analysis of covariance while controlling for confounding variables. Results:Haitian American participants were older (P = .032), had higher fasting plasma glucose (P = .036), and A1C (P = .016), but had lower levels of Hs-CRP (P < .001), insulin and HOMA2-IR and lower abdominal obesity (P = .030), than African Americans. Haitian Americans had significantly lower HOMA2-IR (P = .008) than African Americans when comparing both ethnicities with T2DM, high abdominal obesity, and adiponectin levels lower than the median ( Conclusion: The clinical significance of observed differences in insulin resistance, abdominal obesity, and adiponectin levels between Haitian Americans and African Americans could assist in forming public health policies that are ethnic specific.

The study examined the associations of anthropometric measures of obesity with high sensitivity C-reactive protein (hs-CRP) levels in Turkish immigrants with type 2 diabetes (T2D) living in the Netherlands. A total of 110 participants, physician-diagnosed with T2D, aged 30 years and older were recruited from multiple sources from The Hague, Netherlands. Serum hs-CRP levels were measured with immunoturbidimetric assay. Glycated hemoglobin (A1C) was determined by high-pressure liquid chromatography. Measures of obesity: body weight, body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) were determined. Statistical analysis included descriptive statistics, Pearson’s correlations and multiple linear regressions (MLR) stratified by gender. Hs-CRP was log transformed to achieve normality. Subjects with hs-CRP levels >10 mg/L (n = 17) were excluded from the analysis. Females had a higher BMI (p = 0.007), HC (p < 0.001), and WHtR (p = 0.011) as compared to males. Conversely, males had a higher weight (p = 0.007), and WHR (p < 0.001) than females. MLR showed that after controlling for covariates, log hs-CRP was positively associated with BMI (B = 0.039, SE = 0.019, β = 0.287, p < 0.05), WC (B = 0.025, SE = 0.011, β = 0.332, p < 0.05) and WHtR (B = 4.015, SE = 1.464, β = 0.376, p < 0.01) in females only. Gender-specific associations between obesity measures and hs-CRP level need to be further investigated in the Turkish immigrant population. Hs-CRP assessment may be added as a standard of care for T2D treatment within this population.

Oxidative stress plays a key role in the development of Type 2 Diabetes (T2D). This cross-sectional study examined the relationship among serum levels of manganese superoxide dismutase (MnSOD), 8-hydroxy-2’-deoxyguanosine (8OHdG), dietary antioxidant intakes and glycemic control in African Americans (n=209) and Haitian Americans (n=234) with and without T2D. ^ African Americans had higher BMI (32.8 vs. 29.3 kg/m2), higher energy intake (2148 vs. 1770 kcal), and were more educated as compared to Haitian Americans; all variables were significant at p < .001. Serum levels of 8OHdG and MnSOD for African Americans (1691.0 ± 225.1 pg/ml, 2538.0 ± 1091.8 pg/ml; respectively) were significantly higher than for Haitian Americans (1626.2 ± 222.9, 2015.8 ± 656.3 pg/ml; respectively). 8OHdG was negatively correlated with MnSOD ( r = -.167, p < .001) in T2D. Having T2D was negatively correlated with MnSOD (r = -.337; p < .01) and positively correlated with 8OHdG (r = .500; p < .01). African Americans and Haitian Americans with T2D had fasting plasma glucose (FPG) levels of 143.0 ± 61.0 mg/dl and 157.6 ± 65.5 mg/dl, and A1C of 7.5 ± 1.8 % and 8.4 ± 2.4 %, respectively. African Americans and Haitian Americans without T2D had FPG levels of 95.8 ± 13.2 mg/dl and 98.7 ± 16.9 mg/dl, and A1C of 5.9 ± 0.4% and 6.0 ± 0.5%, respectively. Dietary intakes of vitamin C and vitamin D were negatively correlated with FPG (r = -.21; r = -.19, p < .05) respectively. Carotenoids negatively correlated with A1C (r = -.19, p < .05). Lower levels of MnSOD were associated with lower levels of zinc, r = .10, p < .05, and higher levels of carotenoids r = -.10, p < .05. Higher levels of 8OHdG were associated with lower levels of Vitamin D, r = -.14, p < .01, and carotenoids, r = -.09, p < .05. ^ The results demonstrate greater oxidative mtDNA damage in persons with T2D compared to those without T2D and in African Americans compared with Haitian Americans. The inverse relationship between dietary intake of antioxidants and oxidative stress implies a potential to reduce oxidative stress with diet. ^

Despite research showing the benefits of glycemic control, it remains suboptimal among adults with diabetes in the United States. Possible reasons include unaddressed risk factors as well as lack of awareness of its immediate and long term consequences. The objectives of this study were to, using cross-sectional data, 1) ascertain the association between suboptimal (Hemoglobin A1c (HbA1c) ≥7%), borderline (HbA1c 7-8.9%), and poor (HbA1c ≥9%) glycemic control and potentially new risk factors (e.g. work characteristics), and 2) assess whether aspects of poor health and well-being such as poor health related quality of life (HRQOL), unemployment, and missed-work are associated with glycemic control; and 3) using prospective data, assess the relationship between mortality risk and glycemic control in US adults with type 2 diabetes. Data from the 1988-1994 and 1999-2004 National Health and Nutrition Examination Surveys were used. HbA1c values were used to create dichotomous glycemic control indicators. Binary logistic regression models were used to assess relationships between risk factors, employment status and glycemic control. Multinomial logistic regression analyses were conducted to assess relationships between glycemic control and HRQOL variables. Zero-inflated Poisson regression models were used to assess relationships between missed work days and glycemic control. Cox-proportional hazard models were used to assess effects of glycemic control on mortality risk. Using STATA software, analyses were weighted to account for complex survey design and non-response. Multivariable models adjusted for socio-demographics, body mass index, among other variables. Results revealed that being a farm worker and working over 40 hours/week were risk factors for suboptimal glycemic control. Having greater days of poor mental was associated with suboptimal, borderline, and poor glycemic control. Having greater days of inactivity was associated with poor glycemic control while having greater days of poor physical health was associated with borderline glycemic control. There were no statistically significant relationships between glycemic control, self-reported general health, employment, and missed work. Finally, having an HbA1c value less than 6.5% was protective against mortality. The findings suggest that work-related factors are important in a person’s ability to reach optimal diabetes management levels. Poor glycemic control appears to have significant detrimental effects on HRQOL.

Genetic heterogeneity, lifestyle factors, gene-gene or gene-environment interactions are the determinants of T2D which puts Hispanics and populations with African ancestry at higher risk of developing T2D. In this dissertation, the genetic associations of PPARGC1A polymorphisms with T2D and its related phenotypes (metabolic markers) in Haitian Americans (cases=110, controls=116), African Americans (cases=120, controls=124) and Cuban Americans (cases=160, controls=181) of South Florida were explored. Five single nucleotide polymorphisms of gene PPARGC1A were evaluated in each ethnicity for their disease association. In Haitian Americans, rs7656250 (OR= 0.22, pp=0.03) had significant protective association with T2D but had risk association in African Americans for rs7656250 (OR=1.02, p=0.96) and rs4235308 (OR=2.53, p=0.03). We found that in Haitian American females, both rs7656250 (OR=0.23, pp=0.03) had protective association with T2D. In African American females, rs7656250 (OR=1.14, p=0.78) had risk association whereas in males, it had significant protective effect (OR=0.37, p=0.04). However, the risk association exhibited by rs4235308 was stronger in African American females (OR=2.69, p=0.03) than males (OR=1.16, p=0.72). In Cuban Americans, only rs7656250 showed significant risk association with T2D (OR=6.87, p=0.02) which was stronger in females alone (OR=7.67, p=0.01). We also observed significant differences among correlations of PPARGC1A SNPs and T2D phenotypes. Positive correlation was observed for log Hs-CRP with rs3774907 (pp=0.03) in Cuban Americans respectively. Correlation of log A1C with rs7656250 (p=0.02) was positive in Cuban Americans while it was negative for rs3774907 in Haitian Americans (ppPPARGC1A correlations with T2D and its phenotypes among the three ethnicities studied (ii) the associations of PPARGC1A SNPs showed significant effect modification by sex. The findings suggest that variations in effects of PPARGC1A gene polymorphisms among three ethnicities and between sexes may have biomedical implications for the development of T2D as well as the phenotypes related to T2D.

Oxidative stress plays a key role in the development of Type 2 Diabetes (T2D). This cross-sectional study examined the relationship among serum levels of manganese superoxide dismutase (MnSOD), 8-hydroxy-2’-deoxyguanosine (8OHdG), dietary antioxidant intakes and glycemic control in African Americans (n=209) and Haitian Americans (n=234) with and without T2D. African Americans had higher BMI (32.8 vs. 29.3 kg/m2), higher energy intake (2148 vs. 1770 kcal), and were more educated as compared to Haitian Americans; all variables were significant at p < .001. Serum levels of 8OHdG and MnSOD for African Americans (1691.0 ± 225.1 pg/ml, 2538.0 ± 1091.8 pg/ml; respectively) were significantly higher than for Haitian Americans (1626.2 ± 222.9, 2015.8 ± 656.3 pg/ml; respectively). 8OHdG was negatively correlated with MnSOD (r = -.167, p < .001) in T2D. Having T2D was negatively correlated with MnSOD (r = -.337; p < .01) and positively correlated with 8OHdG (r = .500; p < .01). African Americans and Haitian Americans with T2D had fasting plasma glucose (FPG) levels of 143.0 ± 61.0 mg/dl and 157.6 ± 65.5 mg/dl, and A1C of 7.5 ± 1.8 % and 8.4 ± 2.4 %, respectively. African Americans and Haitian Americans without T2D had FPG levels of 95.8 ± 13.2 mg/dl and 98.7 ± 16.9 mg/dl, and A1C of 5.9 ± 0.4% and 6.0 ± 0.5%, respectively. Dietary intakes of vitamin C and vitamin D were negatively correlated with FPG (r = -.21; r = -.19, p < .05) respectively. Carotenoids negatively correlated with A1C (r = -.19, p < .05). Lower levels of MnSOD were associated with lower levels of zinc, r = .10, p < .05, and higher levels of carotenoids r = -.10, p < .05. Higher levels of 8OHdG were associated with lower levels of Vitamin D, r = -.14, p < .01, and carotenoids, r = -.09, p < .05. The results demonstrate greater oxidative mtDNA damage in persons with T2D compared to those without T2D and in African Americans compared with Haitian Americans. The inverse relationship between dietary intake of antioxidants and oxidative stress implies a potential to reduce oxidative stress with diet. African Americans were significantly younger (53.3 vs. 55.6 years), had higher BMI (32.8 vs. 29.3 kg/m2), higher energy intake (2148 vs. 1770 kcal), and were more educated as compared to Haitian Americans; all variables were significant at p < .001.

Résumé: Problématique : En réponse à la prévalence accrue de la maladie du diabète et au fardeau économique important que représente cette maladie sur le système de santé international, des programmes incitatifs pour les maladies chroniques furent instaurés à travers le monde. Ces programmes visent à inciter les médecins à appliquer les lignes directrices chez leurs patients avec besoin complexe en vue d’améliorer la santé des patients et par la suite de réduire les coûts incombés par le système de santé. Les programmes incitatifs étant nombreux et différents d’un pays à l’autre, les études actuelles ne semblent pas s’entendre sur les répercussions de tels programmes sur la santé des patients atteints de diabète. L’objectif de cette étude est d’évaluer les retombées d’un incitatif financier sur le contrôle glycémique de la population atteinte de diabète du Nouveau-Brunswick, au Canada. Méthodes : Cette étude transversale répétée et de cohorte a été menée grâce à des bases de données administratives du Nouveau-Brunswick contenant des données sur dix ans pour 83 580 patients adultes atteints de diabète et 583 médecins de famille éligibles. La santé des patients a été évaluée au niveau du contrôle glycémique, en mesurant les valeurs moyennes d’A1C annuelles à l’aide de régressions linéaires multivariées. Afin d’évaluer si les médecins changeaient leur pratique avec l’implantation du programme incitatif, nous regardions au niveau de la probabilité de recours annuel à au moins deux tests d’A1C en utilisant des régressions logistiques multivariées. Résultats : La probabilité de recours annuel à au moins deux tests d’A1C était plus élevée dans quatre sous-groupes étudiés : les patients nouvellement diagnostiqués après l’implantation du programme avaient des cotes plus élevées comparées aux nouveaux patients avant l’implantation du programme (OR=1.23 [1.18-1.28]); les patients pour lesquels un médecin avait réclamé l’incitatif comparés aux patients pour lesquels aucun médecin n’avait réclamé l’incitatif (OR=2.73 [2.64-2.81]); les patients pour lesquels un médecin avait réclamé l’incitatif avaient des cotes plus élevées après l’implantation du programme comparé à avant (OR=1.89 [1.80-1.98]); et finalement, les patients suivis par un médecin de famille qui a déjà réclamé l’incitatif avaient des cotes 24% plus élevées (OR=1.24 [1.15-1.34]). Il n’y avait pas de différence dans les valeurs d’A1C annuelles entre les 4 sous-groupes étudiés. Conclusion : L’implantation du programme incitatif a démontré que les médecins ont une meilleure probabilité de prescrire au moins deux tests d’A1C, ce qui suggère une meilleure prise en charge des patients. Cependant, le manque de changement au niveau du contrôle glycémique du patient suggère que l’étude des répercussions de l’incitatif devra être poursuivie afin de voir si elle mène à une amélioration d’issues cliniques chez les patients.

A pesar de los beneficios ya demostrados de un buen control glicémico, la evidencia sugiere que la hemoglobina glicosilada de la mayoría de pacientes diabéticos tipo 2 no se encuentra dentro de metas. Se estima que en Estados Unidos solamente un tercio de los pacientes con diabetes mellitus tipo 2 (DM2) tienen una hemoglobina glicosilada menor de 7% que es lo que sugieren la mayoría de guías actuales. La población con diabetes mellitus tipo2 (DM2) es heterogénea, y múltiples factores afectan el control glicémico. La adherencia a conductas de autocuidado por parte del paciente, la asistencia de forma regular a sesiones educacionales de autocuidado, el auto monitoreo de la glicemia, y la asistencia a controles médicos se ha demostrado que tienen un efecto positivo en el resultado del tratamiento de la DM2. Mantener el peso corporal, la reducción de peso y el consumo de alimentos con bajo índice glucémico también causa mejoría en los parámetros metabólicos. Los agentes hipoglicemiantes orales son uno de los tratamientos más prescritos para un control intensivo de la glucosa. Sin embargo la no adherencia a estos es una de las principales causas de un mal control glicémico, por lo que se han realizado múltiples estudios tratando de dilucidar porque el paciente descontinúa su tratamiento encontrando que el 42.9% olvida tomar el medicamento, el 30.6% no entiende la importancia de tomar el medicamento y 26.5% lo hace por presentar hipoglicemia asociada. Este estudio es de tipo observacional, analítico de casos y controles definiendo al Control: pacientes con hemoglobina mayor de 7% durante su último control en el año 2013 y Caso: pacientes con hemoglobina menor de 7% durante su último control en el año 2013. La Población en estudio son los pacientes diabéticos tipo 2 de clínica metabólica de Ilopango. Tomando como muestra a todos los pacientes con diagnóstico de Diabetes Mellitus tipo 2 que cumplan con los criterios de inclusión. La información fue obtenida de la revisión de los expedientes de las clínicas metabólicas de la unidad médica de Ilopango en donde tienen un registro de aproximadamente 6000 pacientes de los cuales 2500 padecen de diabetes mellitus tipo 2, pero únicamente 825 pacientes cuentan con hemoglobina glicosilada de seguimiento, que fue la muestra. Se evaluaron algunos factores como determinantes en el control o descompensación de la AIc cuando se utiliza la medición de la variable del índice de masa corporal, el tener un IMC por arriba de 25 significo que el 90% de los pacientes estuvieron descompensados (OR: 8.797, IC 5.924, 13.18) con un valor de p=<0.0000001 comparada con aquellos pacientes que su IMC es por debajo de 25. Otro hallazgo encontrado fue el tener una patología asociada, como variable de descompensación de A1c (OR=6.996 IC=4.881, 10.16 p <0.0000001) incrementando en un 37% veces más la descompensación en esta variable no se consideró la severidad de la infección ni tampoco la etiología. Además se analizó como determinante de hemoglobina glicosilada mayor de 7%, el cumplimiento de la terapia que se indica a los pacientes, obteniéndose que para aquellos pacientes que cumplen la terapia indicada están más propensos a tener una hemoglobina glicosilada menor de 7% con una fracción prevenible del 4.34% (OR= 0.8229 IC= 0.6256- 1.082 p= 0.08111 ), como un factor protector asociado a los pacientes con DM, aunque estadísticamente no es significativo ya que tiene un valor de p= 0.08.

BACKGROUND: Diabetes mellitus (DM) increases tuberculosis risk while tuberculosis, as an infectious disease, leads to hyperglycemia. We compared hyperglycemia screening strategies in controls and patients with tuberculosis in Dar es Salaam, Tanzania. METHODS: Consecutive adults with tuberculosis and sex- and age-matched volunteers were included in a case-control study between July 2012 and June 2014. All underwent DM screening tests (fasting capillary glucose [FCG] level, 2-hour CG [2-hCG] level, and glycated hemoglobin A1c [HbA1c] level) at enrollment, and cases were tested again after receipt of tuberculosis treatment. Association of tuberculosis and its outcome with hyperglycemia was assessed using logistic regression analysis adjusted for sex, age, body mass index, human immunodeficiency virus infection status, and socioeconomic status. Patients with tuberculosis and newly diagnosed DM were not treated for hyperglycemia. RESULTS: At enrollment, DM prevalence was significantly higher among patients with tuberculosis (n = 539; FCG level > 7 mmol/L, 4.5% of patients, 2-hCG level > 11 mmol/L, 6.8%; and HbA1c level > 6.5%, 9.3%), compared with controls (n = 496; 1.2%, 3.1%, and 2.2%, respectively). The association between hyperglycemia and tuberculosis disappeared after tuberculosis treatment (adjusted odds ratio [aOR] for the FCG level: 9.6 [95% confidence interval {CI}, 3.7-24.7] at enrollment vs 2.4 [95% CI, .7-8.7] at follow-up; aOR for the 2-hCG level: 6.6 [95% CI, 4.0-11.1] vs 1.6 [95% CI, .8-2.9]; and aOR for the HbA1c level, 4.2 [95% CI, 2.9-6.0] vs 1.4 [95% CI, .9-2.0]). Hyperglycemia, based on the FCG level, at enrollment was associated with tuberculosis treatment failure or death (aOR, 3.3; 95% CI, 1.2-9.3). CONCLUSIONS: Transient hyperglycemia is frequent during tuberculosis, and DM needs confirmation after tuberculosis treatment. Performance of DM screening at tuberculosis diagnosis gives the opportunity to detect patients at risk of adverse outcome.

Explicar el efecto de la resolución de problemas en el AC de DMT2: (alimentación, ejercicio y medicamentos), sobre el control glucémico en función del apoyo social, edad, sexo y años de diagnóstico (factores condicionantes básicos de DMT2). Establecer la validez de la escala de resolución de problemas en el autocuidado (AC) de Diabetes para identificar los factores encontrados en relación a los estilos de resolución de problemas propuestos. Los conceptos y relaciones seleccionadas se derivaron de la Teoría del Déficit de Autocuidado de Orem (TDAC). La muestra fue de 238 adultos, calculada mediante el paquete n´Query Advisor versión 4.0 para un nivel de significancia de .05, una potencia de prueba de 90%, tamaño de efecto de .07 (R2) en el contraste de no significancia del modelo de regresión lineal múltiple con 6 variables independientes. El muestreo fue por conveniencia, se invitó a participar a las personas que acudieron a consulta para control de DMT2 en la Asociación Mexicana de Diabetes de Monterrey Nuevo León. Para medir las variables de interés se utilizaron instrumentos de lápiz y papel y mediciones antropométricas (peso, estatura, circunferencia de cintura) y bioquímicas (A1C a 50 pacientes seleccionados aleatoriamente de la base de datos de la Asociación). Contribuciones y Conclusiones: Del total de la muestra estudiada el 59.7% correspondió a mujeres, el promedio de edad fue de 54.61 años, con 11 años de escolaridad. En promedio tenían 10 años (DE = 1.84; 1-42) de haber sido diagnosticados con DMT2 y habían recibido en promedio 9.7 sesiones de educación sobre su tratamiento en alimentación, ejercicio y medicamentos. Se realizó la adaptación del instrumento para medir resolución de problemas en el cuidado de DMT2, el cual obtuvo confiabilidad aceptable (.84) y validez (3 factores que explicaron el 49% de la varianza total). Los hallazgos sugieren que las habilidades de los pacientes para resolver problemas y realizar las actividades de AC están condicionadas por la edad (β = .16, p ˂ .01) y apoyo social (β = .25, p ˂ .01). Se confirma la proposición teórica de la TGAC de que las habilidades para el AC están condicionadas por la edad. El estilo efectivo mostró asociación con AC en alimentación (rs = .22; p <.01). El estilo evitativo, mostró que a mayor puntaje en este estilo menor AC de alimentación (rs = -.37; p < .01), ejercicio (rs = -.17; p < .01) y medicamentos (rs = -.30; p <. 01). En este estudio no se encontró asociación de la resolución de problemas con HbA1c (rs = -.07; p = .65).

BACKGROUND: The increasing prevalence of diabetes and costly long-term complications associated with poor glycemic control are issues facing health services worldwide. Diabetes self-management, with the support of health care providers, is critical for successful outcomes, however, frequent clinical contact is costly. Text messages via short message service (SMS) have the advantage of instant transmission at low cost and, given the ubiquity of mobile phones, may be the ideal platform for the delivery of diabetes self-management support. A tailored text message-based diabetes support intervention called Self-Management Support for Blood Glucose (SMS4BG) was developed. The intervention incorporates prompts around diabetes education, management, and lifestyle factors (healthy eating, exercise, and stress management), as well as blood glucose monitoring reminders, and is tailored to patient preferences and clinical characteristics. OBJECTIVE: To determine the usability and acceptability of SMS4BG among adults with poorly controlled diabetes. METHODS: Adults (aged 17 to 69 years) with type 1 (n=12) or type 2 diabetes (n=30), a hemoglobin A1c (HbA1c) over 70 mmol/mol (8.6%), and who owned a mobile phone (n=42) were recruited to take part in a 3-month pilot study of SMS4BG. At registration, participants selected the modules they would like to receive and, where appropriate, the frequency and timing of blood glucose monitoring reminders. Patient satisfaction and perceptions of the usability of the program were obtained via semistructured phone interviews conducted at completion of the pilot study. HbA1c was obtained from patient records at baseline and completion of the pilot study. RESULTS: Participants received on average 109 messages during the 3-month program with 2 participants withdrawing early from the study. Follow-up interviews were completed with 93% of participants with all reporting SMS4BG to be useful and appropriate to their age and culture. Participants reported a range of perceived positive impacts of SMS4BG on their diabetes and health behaviors. HbA1c results indicated a positive impact of the program on glycemic control with a significant decrease in HbA1c from baseline to follow-up. CONCLUSIONS: A tailored text message-based intervention is both acceptable and useful in supporting self-management in people with poorly controlled diabetes. A randomized controlled trial of longer duration is needed to assess the efficacy and sustainability of SMS4BG.

Introducción: El tiempo promedio del efecto máximo de la insulina regular rápida en la glucemia postprandial ha sido considerado durante años de 120 minutos. En pacientes con Diabetes Mellitus (DM) que usan insulinas análogas este tiempo y los factores asociados no se encuentran reportados para ser aplicados en el automonitoreo. El objetivo de este estudio fue calcular el tiempo y factores relacionados al efecto máximo de la insulina en la glucemia postprandial. Metodología: Se desarrolló un estudio longitudinal retrospectivo a partir de una fuente secundaria donde se realizó un análisis descriptivo y bivariado con las variables demográficas y clínicas presentes en la población. Resultados: El tiempo promedio del pico máximo de insulina en pacientes con DM1 fue de 78.4 (DE± 16.512) y DM2 75.01(DE± 12.02) minutos. El 75% de la población con DM1 y el 54.2% en DM2 era de sexo femenino, la edad promedio en DM1 era 42.38 años y en DM2 68 años, en cuanto a la categorización del IMC el 50% de la población en DM1 y el 37.5% en DM2 estaban dentro del rango de obesidad y se encontró una relación con respecto al tipo de comida “desayuno-cena” vs el tiempo promedio del efecto máximo de la insulina calculado para ambos grupos (p:0.010). Conclusiones: El tiempo promedio del efecto máximo de la insulina calculado fue menor al tiempo reportado en la literatura clínica de 120 minutos. El tipo de comida principal mostró una relación con el tiempo promedio del efecto máximo en ambos grupos.
