A high risk of morbidity-mortality caused by a harsh and unpredictable environment is considered to be associated with a fast life history (LH) strategy, commonly linked with criminal behavior. However, offenders are not the only group with a high exposure to extrinsic morbidity-mortality. In the present study, we investigated the LH strategies employed by two groups of Polish men: incarcerated offenders (N = 84) as well as soldiers and firefighters (N = 117), whose professions involve an elevated risk of injury and premature death. The subjects were asked to complete the Mini-K (used as a psychosocial LH indicator) and a questionnaire which included a number of biodemographic LH variables. Although biodemographic and psychosocial LH indicators should be closely linked with each other, the actual connection between them is unclear. Thus, this study was driven by two aims: comparing LH strategies in two groups of men with a high risk of premature morbidity-mortality and investigating the relationship between the biodemographic and psychosocial LH dimensions. The study showed that incarcerated men employed faster LH strategies than soldiers and firefighters, but only in relation to biodemographic variables (e.g., number of siblings, age of sexual initiation, life expectancy). No intergroup differences emerged regarding psychosocial LH indicators. Moreover, the correlation analysis showed a weak association between biodemographic and psychosocial LH indicators. The results strengthen the legitimacy of incorporating biodemographic LH traits into research models and indicate the need for further research on the accuracy of the Mini-K. The possible explanations for the intergroup differences in LH strategies are discussed.

罪犯的生活比士兵和消防员快吗？：生命历史理论在生物人口学和社会心理方面的比较。

由恶劣和不可预测的环境引起的高发病率死亡率的风险被认为与通常与犯罪行为有关的快速生活史（LH）策略有关。但是，罪犯并不是唯一一个高度暴露于外在发病率-死亡率的人群。在本研究中，我们调查了两组波兰男子采用的LH策略：被监禁的罪犯（N  = 84）以及士兵和消防员（N = 117），其职业涉及受伤和过早死亡的风险较高。要求受试者完成Mini-K（用作社会心理LH指标）和问卷，其中包括许多生物统计学LH变量。尽管生物人口学和社会心理LH指标应彼此紧密联系，但它们之间的实际联系尚不清楚。因此，这项研究的目的是两个目标：比较两组具有高发病率和死亡率的高风险男性的LH策略，并研究生物人口统计学和社会心理LH维度之间的关系。研究表明，被监禁的男人比士兵和消防员采用的LH策略更快，但仅与人口统计学变量有关（例如，兄弟姐妹的数量，性生活的年龄，预期寿命）。关于社会心理LH指标，没有群体间差异。此外，相关分析表明，生物人口学和社会心理LH指标之间的关联性较弱。研究结果加强了将生物人口学LH特征纳入研究模型的合法性，并表明有必要进一步研究Mini-K的准确性。讨论了LH策略中群体间差异的可能解释。
