The reported prevalence of type 2 diabetes among the Kuwaiti population varied from one source to another. This study was undertaken to define the magnitude of the problem and to suggest plans for future diabetic care. All type 2 Kuwaiti diabetic subjects registered and continuing to attend regularly in two health areas Mubarak Health Area (MHA) and Farwania Health Area (FHA)] were selected for the study. There were 3222 in MHA and 5114 in FHA among the Kuwaiti population aged 20 years and above, accounting for a total crude prevalence of 7.6% in both health areas and for a prevalence rate of 5.6% in MHA and 10.0% in FHA. The age-specific prevalence of type 2 diabetes in both areas combined rose from 2.639 per 100 population in the age group 20-39 years to 15.350% and 26.252% in the age groups 40-59 and 60 and above, respectively. The female to male ratio was 1.7, 1.6, 1.1, respectively, in MHA and 1.7, 2.0, 0.9 in FHA for the age groups 20-39, 40-59, and 60 and above. This study shows that type 2 diabetes is a major public health problem in Kuwait, with a female preponderance. Obesity is a characteristic feature of the population studied, with a mean body mass index of 31.8 +/- 6.3 and 28.5 +/- 5.1 in women and men, respectively. A positive family history of diabetes mellitus was reported in 63% of the diabetic subjects. There is a need to standardize methods of reporting and to plan a national screening survey.

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.

"A variety of life table models were used for the analysis of the (1984-86) Kuwaiti cause-specific mortality data. These models comprised total mortality, multiple-decrement, cause-elimination, cause-delay and disease dependency. The models were illustrated by application to a set of four chronic diseases: hypertensive, ischaemic heart, cerebrovascular and diabetes mellitus. The life table methods quantify the relative weights of different diseases as hazards to mortality after adjustment for other causes. They can also evaluate the extent of dependency between underlying cause of death and other causes mentioned on [the] death certificate using an extended underlying-cause model."

Spirometric testing, including forced vital capacity (FVC), forced expiratory volume in .5 s (FEV0.5), FEF25-75%, and peak expiratory flow resistance (PEFR), was conducted among 130 10-y-old children (67 Kuwaitis, 63 Europeans) who lived with their parents in the same area in Kuwait city. Lung function of children who lived in houses with gas stoves were compared with those who lived in homes supplied with electric cookers. The FEV0.5 for children who lived in households with gas stoves was significantly lower (average difference, 94 ml; p = .05; corrected to height and sex). Other lung function indices, i.e., FVC, FEF25-75%, and PEFR, were also lower but, after accounting for confounders, were not statistically significant. Children from households that were equipped with gas cookers were approximately 3 cm shorter than children who lived in homes with electric cookers. These findings suggest that children who live in a very hot and dry climate--even with efficient air conditioning systems--are susceptible to the same environmental hazards to which children from other climatic zones are exposed. This susceptibility may be more pronounced before or at the onset of puberty.

At 21 locations within the city of Kuwait, continuous weekly measurements were made of oxides of nitrogen (NOx) and of carbon monoxide (CO): analyses were made using a chemiluminescent NOx analyser and a gas filter correlation ambient CO analyser. At 90% of the locations, the daily mean NOx concentrations exceeded 50 ppb, and in peak traffic hours the levels often reached 500 ppb. Similarly, the daily mean concentration of CO at 88% of the locations was greater than or equal to 8 ppm, and at three locations the CO concentrations were greater than 20 ppm. Throughout the week, daily differences were noted, with the lowest concentrations of pollutants recorded at the weekends. The influence of meteorological parameters was examined. The results showed that traffic was a major source of pollution in the city of Kuwait.

On December 31, 1988 there were 201 registered multiple sclerosis patients in Kuwait, an overall prevalence rate (PR) of 10.2 per 100,000; among them were 186 Arabs, of whom 72 were Palestinians and 51 Kuwaitis. Comparison of these two subgroups, who had a similar age distribution revealed that the disease was 2 1/2 times more frequent among Palestinians (PR 23.8/100,000) than among Kuwaitis (PR 9.5/100,000). Palestinians also showed significant differences from Kuwaitis in eye color, blood group distribution and HLA-DR and HLA-DQW epitopes frequency. This suggests that genetic rather than environmental factors might be the underlying cause for the high susceptibility to develop MS among Arabs originating from the Eastern Mediterranean basin.

The 160,000 population in Adan area, Kuwait, is served by Adan Regional Hospital. During the 6 months period mid-December, 1983 to mid-June, 1984, 68 cases of brucellosis were admitted to the hospital, an annual incidence of 85/100,000 population. Of these, 84% were Kuwaitis and Bedouins. The mean age was 32 years, range 12-70 years. The male female ratio was 1.4:1. 55 patients gave histories of consuming raw milk and 4 had close contact with animals. The highest incidence of the disease coincided with the animal delivery season and the desert camping period of Kuwaiti families. It appears that air transmission of contaminated soil is one of the main routes of Brucella infections in Kuwait.

Three hundred seventy-nine Kuwaiti patients with brucellosis were admitted to Adan General Hospital, Kuwait, during the period 1984-1985. Of these 231 were males and 148 were females. Diagnosis was based on symptoms and signs compatible with the disease and on the detection of significantly elevated antibody titer and/or positive blood culture. The primary means of exposure were the consumption of raw milk and contact with goats, sheep, or camels. Patients most frequently presented with fever (91%), chills (40%), sweats (39%), gastrointestinal symptoms (30%), headache (23%), respiratory symptoms (23%), and musculoskeletal symptoms (22%). The major signs were osteoarticular involvement (37%), hepatosplenomegaly (27%), and lymphadenopathy (9%). Different regimens of treatment were used, but the highest rate of cure was achieved with triple therapy--tetracycline, streptomycin, and rifampin.

A pilot survey was designed to define incidence, rotation period, rotation direction and cycle of shiftwork plans in the production and service units in Kuwait. Preliminary results from the Ministry of Interior showed that four different shift plans are widely used. Forty policemen, ten from each shift plan, volunteered to fill in a diary for a period of two or more cycles. The diary was comprised of a set of questions planned to reveal disturbances in sleep duration, sleep quality, food intake and appetite. The daily questionnaire also covered psychosomatic complaints and subjective judgement of recovery. A control group, on permanent day work, volunteered to fill in the diary for the same period. The results indicated that one of the four shift plans was quite satisfactory and least harmful to the policemen. Two plans were associated with excessive strain during working days, but the number of free days was sufficient to achieve complete recovery. The fourth plan was associated with excessive strain during working days and recovery was not achieved after 24 h of rest at the end of the shift cycle.
