“…The incidence rates of type 1 diabetes among 15-19, 20-24, 25-29, and 30-34-year-aged Finish population was 22.5, 16.1, 16.2, and 15.2 per 100,000 person years, respectively (27.1, 19.9, 20.9, 19.8 and 17.6, 12.2, 11.3, 10.3 per 100,000 person years among males and females, respectively) [14]. In Upper Austria (1994-1996), Catalonia, Spain (1989-1998), Turin, Italy (1991-2001), Northern Italy (1984-2004) the average incidence rates of type 1 diabetes among 15-29-year-aged inhabitants were correspondingly 7.1 (95% CI 5.5-9.0), 10.2 (95%CI 9.7-10.8), 6.8 (95%CI 6.3-7.4) and 7.1 (95% CI 6.6-7.7) per 100.000 person years, and like in Lithuania higher than among 0-14-year-aged children [10,11,30,31]. Average annual increases in incidence rates were similar in children and young adults in Northern Italy, not supporting the hypothesis of a shift towards younger age as the main explanation for the increasing temporal trend in children [10].…”
