Inadequate diabetes knowledge is associated with poor glycemia control in patients with type 2 diabetes / El conocimiento inadecuado de la diabetes se asocia con un control glucémico deficiente en pacientes con diabetes de tipo 2

Objective: To identify the association between glycemia control with level of diabetes knowledge, diabetes education, and lifestyle variables in patients with type 2 diabetes. Design: Cross-sectional analytical study. Site: Clinics of the Mexican Institute of Social Security (IMSS), Mexico. Participants: Patients with type 2 diabetes. Main measurements: Glycated hemoglobin (HbA1c), glucose, and lipid profile levels were measured from fasting venous blood samples. Assessment of disease knowledge was performed using the Diabetes Knowledge Questionnaire (DKQ-24). Systolic and diastolic blood pressure was measured. Weight and abdominal circumference were measured, as well as body composition using bioimpedance. Sociodemographic, clinical, and lifestyle variables were obtained. Results: A total of 297 patients were included, sixty-seven percent (67%) were women with a median of six years since the diagnosis of diabetes. Only 7% of patients had adequate diabetes knowledge, and 56% had regular knowledge. Patients with adequate diabetes knowledge had a lower body mass index (p=0.016), lower percentage of fat (p=0.008), and lower fat mass (p=0.018); followed a diet (p=0.004) and had received diabetes education (p=0.002), and to obtain information about their illness (p=0.001). Patients with low levels of diabetes knowledge had a higher risk of HbA1c≥7% (OR: 4.68; 95% CI: 1.48,14.86; p=0.009), as well as those who did not receive diabetes education (OR: 2.17; 95% CI: 1.21–3.90; p=0.009) and those who did not follow a diet (OR: 2.37; 95% CI: 1.01,5.55; p=0.046). Conclusion: Inadequate knowledge of diabetes, lack of diabetes education, and dietary adherence are associated with poor glycemia control in patients with diabetes.(AU)

Objetivo: Identificar la asociación entre el control de la glicemia con el nivel de conocimiento, la educación y las variables de estilo de vida en pacientes con diabetes tipo 2. Diseño: Estudio transversal analítico. Sitio: Clínicas del Instituto Mexicano del Seguro Social, México. Participantes: Pacientes con diabetes tipo 2. Medidas principales: Se midió el nivel de hemoglobina glicosilada (HbA1c), glucosa y perfil de lípidos en ayuno. La evaluación del conocimiento de la enfermedad se realizó con el Cuestionario de Conocimiento de la Diabetes (DKQ-24). Se midió presión arterial, peso y circunferencia abdominal, así como la composición corporal con bioimpedancia. Las variables clínicas y de estilo de vida fueron registradas. Resultados: Se incluyó a 297 participantes y 67% fueron mujeres, con una mediana de diagnóstico de diabetes de seis años. Solo 7% tuvo un conocimiento adecuado de la diabetes y 56% un conocimiento regular. Los pacientes con conocimiento adecuado de la diabetes tuvieron un índice de masa corporal más bajo (p = 0,016), seguían una dieta (p = 0,004), recibieron educación en diabetes (p = 0,002), y obtuvieron información de su enfermedad (p = 0,001). Los pacientes con bajo nivel de conocimiento tuvieron mayor riesgo de HbA1c ≥ 7% (OR: 4,68; IC 95%: 1,48-14,86; p = 0,009), así como aquellos sin educación en diabetes (OR: 2,17; IC 95%: 1,21-3,90; p = 0,009) y quienes no seguían una dieta (OR: 2,37; IC 95%: 1,01-5,55; p = 0,046). Conclusión. El conocimiento inadecuado de diabetes, la falta de educación en diabetes y adherencia a la dieta se asocian a un control glucémico deficiente en pacientes con diabetes.(AU)

Prevalence of type 2 diabetes mellitus in the pediatric population of a third-level care hospital in Mexico City in 2013 and 2018.

BACKGROUND: Diabetes mellitus type 2 (T2DM) is a state of hyperglycemia due to a defect in the secretion and/or action of insulin, and it represents the most common form of diabetes worldwide. In Mexico, 10.3% of the adult population have been diagnosed with T2DM and it is expanding to the pediatric population. AIM: To evaluate and compare the prevalence of T2DM in the pediatric population at the Children's Hospital, "Hospital Infantil de México Federico Gómez (HIMFG)", at two time periods: 2013 vs 2018. METHODS: A comparison of two cross-sectional studies was done (2013 and 2018). The study population was comprised of children and adolescents 8-17 years old, from the Diabetes Clinic at the aforementioned institution. A comprehensive interrogation regarding family history and perinatal antecedents was performed. Complete blood work after 12 h of fasting was obtained to determine serum levels of glucose, glycated hemoglobin, lipid profile, C-peptide, and insulin. The data were analysed using the statistical software package SPSS v. 23.0. A P value of < 0.05 was considered statistically significant. RESULTS: A total of 151 patients were included: 47 from 2013, and 104 from 2018. There were age differences noted between the two periods with younger patients presenting T2DM in 2013. Also, T2DM predominated in the male sex in 55.36% in 2013 vs 32.7% in 2018. An increased prevalence of T2DM was noted from 2013 to 2018 (20.2% vs 33.0%, respectively), which was a statistically significant 12.8% increase (P < 0.0001). The illness phenotype was more aggressive in the 2018 group with the presence of a higher proportion of obesity, insulin resistance, and adverse lipid profiles. CONCLUSION: The prevalence of T2DM at the HIMFG institution from 2013 to 2018 increased by 12.8% (20.2% vs 33.0%, respectively). The study results demonstrate the need for vigilance in T2DM trends, and to strengthen programs of healthy nutrition and physical activity as well as early detection and risk factors for obesity, data on insulin resistance, and metabolic syndrome, with the aim of preventing the development of T2DM.

Diabetes and obesity during pregnancy are associated with oxidative stress genotoxicity in newborns.

Objective To compare the level of oxidative deoxyribonucleic acid (DNA) damage (genotoxicity) between the offspring of mothers with and without diabetes diagnosed during pregnancy and its association with maternal body mass index (BMI). Methods We measured 8-hydroxy-deoxyguanosine (8-OH-dG), a marker of DNA oxidative damage, in venous umbilical cord plasma from newborns of mothers with (n=34) and without (n=56) diabetes diagnoses obtained during pregnancy. Two markers of oxidative stress - namely, nitric oxide degradation products (NOx) and total glutathione (GSH) - were quantified in both mothers and newborns. The effects of BMI, glycated hemoglobin (HbA1c), age and delivery mode were also analyzed. Results Newborns of mothers with diabetes during pregnancy exhibited higher levels of 8-OH-dG than those of mothers without diabetes (P<0.001). The other markers of oxidative stress were also higher in both mothers with diabetes and their newborns, with the exception of NOx in the mothers. The association of diabetes with 8-OH-dG was independent of other analyzed factors. Conclusion The offspring of mothers with diabetes during pregnancy are born with increased genotoxicity than the offspring of mothers without diabetes. BMI and HbA1c display an independent association with 8-OH-dG, particularly in the offspring of mothers not diagnosed with diabetes.
