Crime has been described as a public health issue in Trinidad and Tobago, a small developing nation. COVID-19 restrictions, aimed at maintaining public health safety by limiting disease spread, may have negatively impacted crime rates due to an alteration of social and economic conditions. This study evaluates the implications of these restrictions on crime dynamics and hence their impacts on overall public health.
Employing interrupted time series analysis with seasonal autoregressive integrated moving average with exogenous factor (Seasonal Autoregressive Integrated Moving Average with Exogenous Variables) models, monthly data on murders, sexual offences, and motor vehicle larcenies from January 2013 to June 2023 were analysed.
The study found a decrease in murders and motor vehicle larcenies with the onset of restrictions, followed by an inverse trend correlating with the easing of measures. Sexual offences showed no significant change in response to the restrictions.
While COVID-19 restrictions initially influenced certain crime rates, the effect varied across crime types. Policy interventions based on lessons learned from the COVID-19 pandemic must be done to strategically reduce and prevent crime without having the negative side effects of the pandemic.
在特立尼达和多巴哥这个小型发展中国家,犯罪已被视为一个公共卫生问题。旨在通过限制疾病传播来维护公共卫生安全的新冠疫情限制措施,可能因社会和经济状况的改变而对犯罪率产生了负面影响。本研究评估了这些限制措施对犯罪动态的影响,以及因此对整体公共卫生的影响。
采用带有外生因素的季节性自回归积分滑动平均模型(Seasonal Autoregressive Integrated Moving Average with Exogenous Variables)进行中断时间序列分析,对2013年1月至2023年6月期间的谋杀案、性犯罪和机动车盗窃案的月度数据进行了分析。
研究发现,随着限制措施的实施,谋杀案和机动车盗窃案有所减少,随后出现了与措施放宽相关的反向趋势。性犯罪对限制措施没有显示出显著变化。
虽然新冠疫情限制措施最初影响了某些犯罪率,但影响因犯罪类型而异。必须根据从新冠疫情中学到的经验教训进行政策干预,以战略性地减少和预防犯罪,同时避免疫情带来的负面影响。
