title: Pattern of non-insulin dependent diabetes mellitus in Kuwait.
abstract: The aim of this study was to examine distinctive clinical characteristics of non-insulin dependent diabetes mellitus (NIDDM) patients in Kuwait including mode of presentation at diagnosis, family history of diabetes, therapeutic management and response to treatment. We studied 3299 Kuwaiti patients (1454 male (M) and 1845 female (F) subjects) registered in Salmiya diabetic clinic, a part of the national network of diabetes control and care programme, and located in the urban Hawally Governorate, Kuwait. The mean age of the patients was 53 years (+/- 13.9 years), and 73.8% were in the age group 45-64 years. The majority of patients (53.6%) were diagnosed as they were clinically symptomatic; in contrast a significant minority (37.8%) were diagnosed by chance mainly during investigation for unrelated events. The 8.6% of the women diagnosed during pregnancy had a high parity index 6.5 +/- 2.9. A high percentage of the diabetic patients (63%) reported a positive family history in first degree relatives. The mean duration of diabetes mellitus was 7.8 years (range 2-28 years) and 70% of the patients had diabetes mellitus for 9 years or less. The mean body mass index (BMI) was 31.8 +/- 6.3 kg/m2 and 28.5 +/- 6.3 kg/m2 in women and men, respectively. Among the diabetic women 57.7% were obese (BM > 30 kg/m2) and 30.2% were overweight (BMI 25-30 kg/m2) as compared to 33.6% and 44.3% among diabetic men, respectively. High blood pressure (> or = 160/95 mmHg) was reported in 14.9%. The main therapeutic modality in the majority of patients, (63.2%), was the administration of oral hypoglycaemic agents (OHA), while 23.7% were on a diet regimen and only 13.1% were on insulin therapy. The study throws light on the pattern of NIDDM among Kuwaiti patients. Frequent association with obesity suggests that it may be a major risk factor. The strong familial aggregation reported paves the way for future research among these families for cosegregation of a defined genetic trait with NIDDM in the Arab population subset.
