Resumen
Introducción: el Finnish Diabetes Risk Score (FINDRISC) mostró
alta sensibilidad y especificidad para la detección de personas que
evolucionarían a diabetes mellitus (DM) en las poblaciones estudia-
das, por lo cual se decidió utilizarlo entre quienes concurrieron por
diferentes motivos a realizarse análisis de laboratorio en centros de
la Asociación de Laboratorios de Alta Complejidad (ALAC), con el
objeto de identificar personas con diferentes niveles de riesgo de
presentar alteraciones de la glucemia en ayunas (GA) y de la HbA1c.
Objetivos: explorar la asociación entre la puntuación del
FINDRISC con GA y HbA1c, estableciendo el punto de cor-
te de mayor sensibilidad y especificidad para encontrar una
GA ≥100 mg/dL y una HbA1c ≥5,7% (38,8 mmol/mol), en una
población que concurrió a centros de la ALAC.
Materiales y métodos: se incluyeron 1.175 individuos de 45 labo-
ratorios de la ALAC, procesamiento local de glucemia y centrali-
zado de HbA1c (high performance liquid chromatography, HPLC).
Análisis estadístico: chi-cuadrado, Odds Ratio, ANOVA, test de
Tukey, regresión logística binomial y curvas ROC.
Resultados: los puntajes totales del FINDRISC se asociaron de
manera positiva y estadísticamente significativa, tanto con los va-
lores de GA como con los niveles de HbA1c. Entre sus variables,
una edad mayor o igual a 45 años, un perímetro abdominal de alto
riesgo, un índice de masa corporal mayor o igual a 25 Kg/m2
, la
presencia de antecedentes familiares de DM (padres, hermanos
o hijos) y la existencia de antecedentes de medicación antihiper-
tensiva se asociaron de manera significativa con valores de GA
iguales o superiores a 100 mg/dL y/o niveles de HbA1c iguales o
mayores a 5,7% (38,8 mmol/mol). No se halló asociación signifi-
cativa con la realización de actividad física (al menos 30 minutos
diarios) ni con el registro de ingesta diario de frutas y verduras.
Los valores medios de GA y HbA1c en individuos con punta-
jes totales del FINDRISC menores o iguales a 11 fueron de
89,9 mg/dL y 5,2% (33,0 mmol/mol), respectivamente, elevándose
hasta valores medios de 116,1 mg/dL y 6,1% (43,0 mmol/mol) en
los individuos con puntajes iguales o superiores a 21, siguien-
do una asociación del tipo “dosis/respuesta”. Por curvas ROC,
un FINDRISC de 13 presenta una sensibilidad del 81,89%, es-
pecificidad del 67,60% y 70,55% de diagnósticos correctos de
HbA1c ≥5,7% (38,8 mmol/mol), y una sensibilidad del 72,50%,
especificidad del 70,62% y 71,20% de diagnósticos correctos
para encontrar personas con una GA ≥100 mg/dL.
Conclusiones: el puntaje del FINDRISC se relacionó con niveles
crecientes de GA y HbA1c, resultando útil para encontrar perso-
nas con GA ≥100 mg/dL y HbA1c ≥5,7% (38,8 mmol/mol) en la
población estudiada.
Introduction: the Finnish Diabetes Risk Score (FINDRISC) has high sensitivity and specificity for the identification of people at risk of diabetes mellitus (DM) in various populations. There- fore, we aimed to use this index to identify individuals at risk of having alterations in fasting glycemia (FG) and HbA1c among those who underwent laboratory analysis at ALAC, Argentina. Objectives: to explore the relationships of the FINDRISC score with the fasting blood glucose (FG) concentration and glycated hemoglobin (HbA1c) level, and to establish appropria- te cut-off scores to predict FG ≥100 mg/dL and HbA1c ≥5.7% (38.8 mmol/mol) in this population. Materials and methods: we recruited 1,175 individuals from 45 ALAC laboratories for whom FG and HbA1c had been mea- sured. We analyzed the data using the chi square test, odds ratios, ANOVA plus Tukey’s post-hoc test, binomial logistic re- gression, and receiver operating characteristic (ROC) curves. Results: total FINDRISC score significantly positively correla- ted with both FG and HbA1c. Of the constituent variables, age ≥45 years, a large waist circumference, a body mass index ≥25 kg/m2 , a close family history of DM, and the use of anti- hypertensive medication were significantly associated with FG ≥100 mg/dL and/or HbA1c ≥5.7% (38.8 mmol/mol). However, no significant association was found with physical activity or the daily consumption of fruit and vegetables. The mean FG and HbA1c for individuals with total FINDRISC scores ≤11 were 89.9 mg/dL and 5.2% (33.0 mmol/mol), respectively, which increased to 116.1 mg/dL and 6.1% (43.0 mmol/mol) for individuals with scores ≥21, with a dose/response-type relationship. ROC analysis showed that a FINDRISC of 13 was associated with a sensitivity of 81.89%, a specificity of 67.60%, and a correct diagnosis rate of 70.55% for HbA1c ≥5.7% (38.8 mmol/mol); and a sensitivity of 72.50%, a specificity of 70.62%, and a correct diagnosis rate of 71.20% for FG ≥100 mg/dL. Conclusions: FINDRISC score increases with increasing FG and HbA1c, and is a useful means of identifying people with FG ≥100 mg/dL and HbA1c ≥5.7% (38.8 mmol/mol).
