Physical inactivity changes in Croatia: the CroHort study.

The aim of this paper was to compare the surveys conducted respectively in 2003 and 2008 within the Croatian Adult Health Cohort Study (CroHort) regarding the physical activity/inactivity of the inhabitants of the Republic of Croatia. The collected data show a significant decline in the intensity of physical activity in 2008 with regards to 2003, regarding the way of getting to work (60.7%), the level of physical strain at work (72.2%), and the frequency of physical activity taken in the subjects' spare time (55.8%). In order to prevent the risk of cardiovascular diseases and to raise the public awareness of the potential health threat physical inactivity poses, a number of thoroughly conceived health promotion strategies should be implemented, which would equally encompass all the segments of Croatian society.

Alcohol-related road traffic accidents before and after the passing of the Road Traffic Safety Act in Croatia.

The aim of this study was to gather enough data in order to formulate theory- and research-based recommendations to policy makers with the intention of decreasing the number of alcohol-related accidents and victims on Croatian roads. The data on the injured traffic participants and the share of participants under the influence of alcohol were collected from the police reports of the Traffic Police Department, Ministry of the Interior, written at the scene of the respective accidents. This documentation was then processed by descriptive epidemiology and analysed through a four-year period, before and after the passing of the New Road Traffic Safety Act in the Republic of Croatia, on 20 August 2004. In the first six months of 2005, after the passing of the Act, there were 3,275 accidents caused by the motorists under the influence of alcohol (12.5% of all the accidents), with 64 persons killed. Only 5 fatalities (8%) were caused by the drivers with measured blood alcohol concentration of up to 0.5 per thousand. As much as 27 fatalities (42%) were caused by the drivers with measured more than 1.5 per thousand, while half of the fatalities, 32 (50%), were caused by drivers with 0.5-1.5 per thousand. In this period, more than 451,000 violations were recorded, whereas in the same period of the previous year, the number of violations was about 519,000. A reduction of the total number of accidents is the result of the new regulation provision, according to which the incidents without human victims do not have to be reported to the police. The number of traffic accidents caused by drivers under the influence of alcohol had increased by some dozen per cents, namely: 2005 - 6,219 persons, 2006- 6,590 persons, noting that in 2006 one less person was killed (123) compared to 2005. In 2005, drivers with alcohol concentration of 0-0.5 per thousand caused 1,096 accidents, with 14 fatalities, whereas in 2006 there were 1,164 accidents with 9 fatalities. A total of 2,314 accidents were caused by drivers with more than 0.5 per thousand and up to 1.5 per thousand in 2005 (in 2006 - 2,582), along with 53 fatalities (1 fewer than in 2006). Drivers with more than 1.5 per thousand participated in 2,809 accidents (2006 - 2,844), with the number of killed drivers amounting to 57, three fewer than in 2006. In light of these facts, alcohol use still remains a significant factor in road traffic accidents and is an important area for injury prevention efforts.

Civil aviation rules on crew flight time, flight duty, and rest: comparison of 10 ICAO member states.

INTRODUCTION: Members of the International Civil Aviation Organization (ICAO) use various criteria to control flight crew scheduling and rest periods with the intention of reducing fatigue and thus improving airline safety. Comparison of these rules across nations may allow future harmonization of the criteria. METHODS: The regulations of 10 ICAO member states were compiled to determine the factors used by each to control scheduling. RESULTS: We identified 12 factors that are used by member states in their regulations; specific nations use 4-7 of these factors. The most frequently used criteria and the number of states using them include Duty Time (N = 8), Crew Augmentation (N = 8), Night Flight (N = 7), Number of Flight Segments (pairs of takeoffs and landings--T/L) (N = 6), Flight Range (N = 6), Flight Time (N = 5), and Number of Crew (N = 5). All 10 states have established limits on Flight Time and/or Duty Time, and 6 have requirements related to Previous Rest and/or Night Sleep. Seven member states undertake regulation of Night Flying, but they vary in defining "night" and the maximum permissible duration of night duty. All states limit flying hours on a monthly and yearly basis, but the specified limits vary. DISCUSSION: Although the 10 states in this study have common aims and premises for regulating crew duty, their regulations diverge with respect to details, using different tools in an effort to prevent the occurrence of excessive fatigue in aircrew members.
