Article: Nutritional causes of anemia in Mexican children under 5 years. Results from the 2006 National Health and Nutrition Survey.[show abstract] [hide abstract]
ABSTRACT: To describe the frequency and severity of anemia and the nutritional variables associated to hemoglobin levels (Hb) in children <5 years of age. We studied 981 children measuring hemoglobin and serum concentrations of ferritin, soluble transferrin receptors (sTfR), C-reactive protein (CRP), zinc, iron, copper, magnesium, folate and vitamin B12. Ordinal logit or multiple regression models were constructed to assess the risk for anemia and the associations among nutritional variables. The overall prevalence of anemia was 20.6%, of which 14% were mild cases and 6.38% moderate. Anemia was associated with iron deficiency (ID) in 42.17% of the cases, whereas ID coexisted with either folate or vitamin B12 deficiency in 9%. Only 2% of cases of anemia were associated with either folate or vitamin B12 deficiencies. CRP (coef: 0.17 g/dl) and third tertile of s-copper (coef: -0.85 g/dl) were associated to unexplained anemia (p<0.05). ID is the main cause of anemia in children <5 y. Folate and vitamin B12 concentrations were associated with anemia. CRP was associated to unexplained anemia. However, vitamin A deficiency, which is associated with anemia, was not studied.Salud publica de Mexico 04/2012; 54(2):108-15. · 0.94 Impact Factor
Article: Prevalence and distribution of type 2 diabetes mellitus in Mexican adult population: a probabilistic survey.[show abstract] [hide abstract]
ABSTRACT: To describe the prevalence, distribution and degree of control of type 2 diabetes (T2D) in Mexican population. Subjects were classified as previously diagnosed T2D (PD); or as "finding of the survey" (FS) (glucose >or=126 mg/dL). Hemoglobin A1c was measured in PD-subjects. The prevalence for PD-T2D was 7.34% (95%CI 6.3, 8.5) and for FS 7.07% (95%CI 6.1, 8.1), summing 14.42%; (7.3 million diabetics). 5.3% of PD-T2D were in good, 38.4% in poor and 56.2% very poor control. Older age (OR=0.96, 95%CI 0.94, 0.97), lower BMI (OR=0.95, 95%CI 0.91, 1.0), were protective for poor control. Affiliation to private services (OR=1.77, 95%CI 0.98, 3.13), larger T2D duration (OR=1.05, 95%CI 1.01, 1.08), and combining oral medication and insulin (OR=16.1, 95%CI 1.61, 161) were riskier. We found an alarming prevalence of T2D in Mexican population; the majority of PD diabetics are in poor control. Research on the latter is warranted.Salud publica de Mexico 01/2010; 52 Suppl 1:S19-26. · 0.94 Impact Factor
Article: Prevalence and distribution of type 2 diabetes mellitus in Mexican adult population. A probabilistic survey[show abstract] [hide abstract]
ABSTRACT: Objetivo. Describir la prevalencia, distribución y grado de control de diabetes tipo 2 (DT2) en población mexicana. Material y métodos. Los sujetos fueron clasificados como �previamente diagnosticados� (PD) o �hallazgos de la encuesta� (FS) (glucosa =126 mg/dL). La hemoglobina A1c se midió en DT2-PD. Resultados. La prevalencia de DT2-PD fue 7.34% (IC95% 6.3, 8.5) y 7.07%.(IC95% 6.1, 8.1) para FS, sumando 14.42% (7.3 millones de diabéticos). Los DT2-PD tenían 5.3% control bueno, 38.4%, malo y 56.2% muy malo. Tener mayor edad (RM=0.96, IC95% 0.95, 0.97) o IMC más bajo (RM=0.95, IC95% 0.91, 1.0) fueron protectores contra mal control. Atenderse en servicios médicos privados (RM=1.77, IC95% 0.98, 3.13), larga duración de DT2 (RM=1.05, IC95% 1.01, 1.08) o recibir hipoglucemiantes más insulina (RM=16.1, IC95% 1.61, 161) fueron de riesgo. Conclusiones. Existe una prevalencia alarmante de DT2 en la población mexicana, la mayoría de los PD-DT2 tenían mal control glicémico.
