We used a panel design and the Nationwide Inpatient Sample from 19 states between 2003 and 2010 to examine the impact of texting bans on crash-related hospitalizations. We conducted conditional negative binomial regressions with state, year, and month fixed effects to examine changes in crash-related hospitalizations in states after the enactment of a texting ban relative to those in states without such bans. Results indicate that texting bans were associated with a 7% reduction in crash-related hospitalizations among all age groups. Texting bans were significantly associated with reductions in hospitalizations among those aged 22 to 64 years and those aged 65 years or older. Marginal reductions were seen among adolescents. States that have not passed strict texting bans should consider doing so.
我们采用面板设计，并利用2003年至2010年间来自19个州的全国住院患者样本，来研究短信禁令对与车祸相关的住院情况的影响。我们进行了带有州、年份和月份固定效应的条件负二项回归，以检验在实施短信禁令后，有禁令的州与没有此类禁令的州相比，与车祸相关的住院情况的变化。结果表明，短信禁令使所有年龄组中与车祸相关的住院人数减少了7%。短信禁令与22至64岁人群以及65岁及以上人群的住院人数减少显著相关。青少年中的住院人数有少量减少。尚未通过严格短信禁令的州应考虑这样做。
