Abstract
Objectives
There are few data concerning the incidence rates of diabetes in Iran. This study
aimed to determine the incidence of diabetes and its risk factors in a middle-aged
population in Iran.
Methods
All of the people who participated in the first phase of the Shahroud eye cohort study
were invited to the study in 2014; after signing informed consent forms, a total of
4737 people 45 to 69 years of age were enrolled in the second phase of the study (participation
rate: 91.3%). The 5-year incidence rate of diabetes was determined by age and sex,
and we used the binomial logistic regression model to calculate the risk ratio.
Results
The prevalence of diabetes in the second phase was 20.19% in men, 26.45% in women
and 23.89% in the total group. The 5-year incidence of diabetes was 11.19% in men,
15.55% in women and 13.73% in both sexes. With increases in age, the incidence of
diabetes rose in both sexes. Age (risk ratio [RR]: 1.02; CI 95%: 1.01 to 1.03) hypertension
(RR: 1.41; CI 95%: 1.15 to 1.74), being overweight (RR: 2.17; CI 95%: 1.64 to 2.88)
and obesity (RR: 3.4; CI 95%: 2.53 to 4.41) were associated with increased risks for
the incidence of diabetes.
Conclusions
This study is 1 of the few studies in Iran that has reported the incidence of diabetes.
Because the incidence of diabetes was high in the studied population, it is necessary
for the health system to design and implement emergency intervention to prevent further
spread of diabetes and its complications.
Résumé
Objectifs
On dispose de peu de données sur les taux d'incidence du diabète en Iran. La présente
étude avait pour but de déterminer l'incidence du diabète et ses facteurs de risque
dans une population d'âge mûr de l'Iran.
Méthodes
En 2014, nous avons invité à l'étude toutes les personnes qui avaient participé à
la première phase de l'étude Shahroud Eye Cohort Study (ShECS); après la signature
des formulaires de consentement éclairé, nous avons inscrit un total de 4737 personnes
de 45 à 69 ans à la deuxième phase de l'étude (taux de participation : 91,3 %). Nous
avons déterminé le taux d'incidence du diabète après 5 ans selon l'âge et le sexe,
et nous avons utilisé le modèle de régression logistique binomiale pour calculer le
risque relatif.
Résultats
À la deuxième phase, la prévalence du diabète était de 20,19 % chez les hommes, de
26,45 % chez les femmes et de 23,89 % pour la totalité du groupe. L'incidence du diabète
après 5 ans était de 11,19 % chez les hommes, de 15,55 % chez les femmes et de 13,73
% chez les deux sexes. Avec l'avancement en âge, l'incidence du diabète augmentait
chez les deux sexes. L'âge (risque relatif [RR] : 1,02; IC à 95 % : 1,01 à 1,03),
l'hypertension (RR : 1,41; IC à 95 % : 1,15 à 1,74), l'excès de poids (RR : 2,17;
IC à 95 % : 1,64 à 2,88) et l'obésité (RR : 3,4; IC à 95 % : 2,53 à 4,41) étaient
associés à l'augmentation des risques de l'incidence du diabète.
Conclusions
Cette étude est l'une des rares études réalisées en Iran qui a rapporté l'incidence
du diabète. Puisque l'incidence du diabète était élevée dans la population étudiée,
le système de santé doit concevoir et mettre en place une intervention d'urgence pour
empêcher la propagation du diabète et de ses complications.
