Aims To provide age–gender standardized incidence rate, temporal trend and seasonal variation of Type 1 diabetes in Kuwaiti children aged ≤ 14 years. Methods Data were prospectively collected over a period of 6 years (1992–1997) according to the DiaMond Project protocol using the capture–recapture method of ascertainment. Results Data ascertainment varied between 90% and 96%. The incidence rate of Type 1 diabetes was 20.1 per 100 000 children 0–14 years (95% confidence interval (CI) 18.0–22.1); age‐standardized incidence rate 20.9 (95% CI 18.8–23.0). The incidence rate among boys, 21.1 per 100 000 (95% CI 18.1–24.1) was slightly higher than that among girls, 19.0 per 100 000 (95% CI 16.1–21.8). The age‐standardized incidence rate was 21.9 (95% CI 18.9–24.8) in boys, and 19.9 (95% CI 17.1–22.8) in girls. Incidence rates increased with age in both sexes (boys χ 2 for linear trend = 13.5, P < 0.001; and for girls χ 2 = 27.8, P < 0.0001). There was a significant trend towards increase in overall incidence during the 6‐year period (χ 2 = 6.210, P = 0.013), and in age group 5–9 (χ 2 = 10.8, P = 0.001). Seasonality was demonstrated overall, in boys and girls ( P < 0.001). Conclusion The incidence of Type 1 diabetes in Kuwait is high compared with the neighbouring Arab countries, and it appears to be increasing as in many European populations.
