Summary
Crime rates may be linked to maternal age. A study found similarities between U.S. crime figures and the maternal age of mothers 17 years prior, suggesting a potential connection in crime epidemiology.
Area of Science:
- Criminology
- Developmental Psychology
- Epidemiology
Background:
- Maternal age is negatively associated with offspring externalizing behavior.
- Childhood externalizing behavior is positively associated with later juvenile delinquency.
Purpose of the Study:
- To test the prediction that cohort changes in crime rates are associated with maternal age at childbirth.
- To explore potential causality in the relationship between maternal age and crime rates.
Main Methods:
- Comparison of U.S. crime statistics from 1987-1997.
- Analysis of maternal age data from 1970-1980 (17 years prior to crime data).
- Time series analysis to assess resemblance between crime rates and maternal age cohorts.
Main Results:
- A close resemblance was observed between the crime rate time series and maternal age time series.
- The findings suggest a plausible association between maternal age and crime rates over time.
Conclusions:
- The study provides plausible evidence for a link between maternal age and crime rates.
- Further research is needed to establish causality and understand the underlying mechanisms.
- Results may inform crime epidemiology and prevention strategies.

491
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

4.8K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

81.8K
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...
