Health Disparities among Rural Individuals with Mental Health Conditions: A Systematic Literature Review

Causal effects of various types of physical activities on psychiatric disorders: a Mendelian randomization study

Background

Psychiatric disorders (PD) pose a significant burden, with vast prevalence and mortality, inflicting substantial costs on individuals and society. Despite its widespread prevalence, the complex pathogenesis of PD remains elusive, leading to limited and challenging therapeutic development. An emerging risk factor for chronic diseases, prolonged sedentary behavior, contrasts with the therapeutic potential of exercise, regardless of its intensity, for various ailments, including PD. Yet, the diversity in exercise modalities and intensities may offer varied impacts on health. This study, leveraging Mendelian Randomization (MR), seeks to investigate the causal relationship between exercise and PD, aiming to elucidate the optimal exercise modality and intensity for PD mitigation while addressing potential confounders.

Methods

This study employed a Mendelian randomization analysis using the genome-wide association study (GWAS) database to investigate the causal relationship between types of physical activity and psychiatric disorders. Sensitivity analysis was conducted to demonstrate the reliability and robustness of the results.

Results

In the past 4 weeks, engaging in a substantial amount of DIY physical activity was found to have a causal relationship with psychiatric disorders (IVW: OR = 0.228, 95% CI: 0.113-0.461, P = 0.000038). As for the types of exercises, there may be a potential causal association between aerobic training (including swimming, cycling, fitness, and bowling) and psychiatric disorders (IVW: OR = 0.322, 95% CI = 0.148-0.704, P = 0.004). However, there was no causal relationship found between mild DIY physical activity and psychiatric disorders (IVW: OR = 0.918, 95% CI = 0.417-2.021, P = 0.831). Furthermore, it seems that there is no causal relationship between vigorous exercise and psychiatric disorders (IVW: OR = 2.705, 95% CI = 0.081-3.419, P = 0.578).

Conclusion

Our study confirms that only a certain level of training activity can have a protective effect on psychiatric disorders, while mild physical activity or vigorous training does not have an impact on psychiatric disorders.

A comparison of two strategies to assess sexual violence: general vs. specialised trauma screening strategies in two high-risk substance use health disparity samples

Background/Objective: Using two different high-risk samples, the present study compared and contrasted two different strategies/questionnaire types for assessing a history of sexual violence: a general trauma screening vs. specialised behaviourally-specific questionnaires.Methods: Sample 1 included 91 men and women seeking detoxification treatment services in a publicly funded, urban clinic who completed a trauma and substance use questionnaire battery during treatment. Sample 2 included 310 women at a rural college who completed a trauma and religious coping questionnaire battery for course credit. All participants completed both types of questionnaires: One general trauma screening questionnaire (i.e. the Life Events Checklist [LEC]) and two behaviourally-specific specialised questionnaires (i.e. the 2007 Sexual Experiences Survey [SES] and the Childhood Trauma Questionnaire [CTQ]).Results: There were large differences in the cases identified by the behaviourally-specific questionnaires (SES and CTQ) compared to the general trauma screening questionnaire (the LEC) in both samples but few differences in the prevalence rates of sexual violence detected by each questionnaire type. In the detoxification sample, the differences were especially notable for men. Follow-up analyses indicated that degree of traumatisation impacted results likely by increasing participant's willingness to endorse face-valid items on the LEC.Conclusions: For men, the behaviourally-specific questionnaires (SES/CTQ) were necessary to identify cases. For those with more severe trauma histories, the LEC was equivalent to the SES/CTQ in identifying a similar number of sexual violence cases. Thus, clinicians and researchers should consider the population when selecting assessments to identify sexual violence history.
