Risky Behaviors and Their Attributable Fractions of Traffic Collisions With Injuries in 2001 and in 2004 Among Participants: GAZEL Cohort, France, 2001−2005

	2001			2004			Change in Prevalence,a %	Change in AF, %
Risky Behaviors	Prevalence	Pd, %	AF, %	Prevalence	Pd, %	AF, %
Reporting a maximum speed of more than 65 km/h in built-up areas	0.238	7.70	7.41	0.108	3.63	2.75	−52.8***	−49.4
Reporting a maximum speed of more than 100 km/h on rural roads	0.764	11.50	11.30	0.442	6.99	5.19	−39.2***	−54.1
Reporting a maximum speed of more than 145 km/h on highways	0.245	7.90	8.02	0.081	2.75	2.81	−65.2***	−65.0
Driving while alcohol intoxicated once per month or more	0.003	0.72	0.59	0.006	1.55	1.75	+115.3***	+196.6
Always answering the phone while driving	0.050	4.20	3.37	0.023	2.01	3.95	−52.1***	+17.2
Driving while sleepy a few times a year or more	0.372	14.06	14.28	0.365	13.85	12.0	−0.01	−16.0

Note. Pd = proportion of cases (participants having reported at least 1 injury road traffic collision) exposed to risk behaviors; AF = attributable fraction of traffic collisions with injuries calculated with adjusted rate ratios. The GAZEL cohort comprises employees and retirees of the French national electricity and gas company.

^aPEs in 2001 and in 2004 were compared with the nonparametric McNemar test.
