摘要
Aims This study estimated, with high spatial and temporal specificity, individuals' risk of being assaulted relative to their momentary proximity to alcohol outlets during daily activities. Design Case-control study. Setting Philadelphia, PA, USA. Participants Cases were 194 non-gun assault victims and 135 gun assault victims aged between 10 and 24 years. Age-matched controls (n = 274) were selected using random-digit dialing. Measurements Participants described minute-by-minute movements (i.e. activity paths) during the course of the day of the assault (cases) or a recent randomly selected day within 3 days of interview (controls). The dependent measure was being an assault case compared with a non-assault control. The main independent measures were participants' momentary proximity to alcohol outlets. The units of analysis were 10-minute segments beginning at 4: 00 a.m. Findings Proximity to bars and restaurants was associated with decreased odds of non-gun assault before 1 p.m. [e.g. 7 a.m. to 9: 59 a.m.: odds ratio (OR) = 0.78; 95% confidence interval (CI) = 0.64, 0.94; P = 0.008], and increased odds after 7 p.m. (e.g. 1 a.m. to 3: 59 a.m.: OR = 1.96; 95% CI = 1.24, 3.09; P = 0.004). Proximity to beer stores was associated with increased odds before 1 p.m. (e.g. 7 a.m. to 9: 59 a.m.: OR = 2.34; 95% CI = 1.58, 3.46; P < 0.001) and from 4 p.m. to 6: 59 p.m. (OR = 1.50; 95% CI = 1.14, 1.96; P = 0.004), but decreased odds after 7 p.m. (e.g. 1 a.m. to 3: 59 a.m.: OR = 0.28; 95% CI = 0.12, 0.63; P = 0.002). Proximity to alcohol outlets was mostly unrelated to risks for gun assault. Conclusions Individuals in areas with greater densities of bars and restaurants and beer stores appear to be at increased risk for non-gun assault at times when these outlets are likely to be patronized most heavily.
