Prison environment and non-communicable chronic disease modifiable risk factors: length of incarceration trend analysis in Mexico City

Mass incarceration as a driver of the tuberculosis epidemic in Latin America and projected effects of policy alternatives: a mathematical modelling study

BACKGROUND

Tuberculosis incidence is increasing in Latin America, where the incarcerated population has nearly quadrupled since 1990. We aimed to quantify the impact of historical and future incarceration policies on the tuberculosis epidemic, accounting for effects in and beyond prisons.

METHODS

In this modelling study, we calibrated dynamic compartmental transmission models to historical and contemporary data from Argentina, Brazil, Colombia, El Salvador, Mexico, and Peru, which comprise approximately 80% of the region's incarcerated population and tuberculosis burden. The model was fit independently for each country to incarceration and tuberculosis data from 1990 to 2023 (specific dates were country dependent). The model does not include HIV, drug resistance, gender or sex, or age structure. Using historical counterfactual scenarios, we estimated the transmission population attributable fraction (tPAF) for incarceration and the excess population-level burden attributable to increasing incarceration prevalence since 1990. We additionally projected the effect of alternative incarceration policies on future population tuberculosis incidence.

FINDINGS

Population tuberculosis incidence in 2019 was 29·4% (95% uncertainty interval [UI] 23·9-36·8) higher than expected without the rise in incarceration since 1990, corresponding to 34 393 (28 295-42 579) excess incident cases across countries. The incarceration tPAF in 2019 was 27·2% (20·9-35·8), exceeding estimates for other risk factors like HIV, alcohol use disorder, and undernutrition. Compared with a scenario where incarceration rates remain stable at current levels, a gradual 50% reduction in prison admissions and duration of incarceration by 2034 would reduce population tuberculosis incidence by over 10% in all countries except Mexico.

INTERPRETATION

The historical rise in incarceration in Latin America has resulted in a large excess tuberculosis burden that has been under-recognised to date. International health agencies, ministries of justice, and national tuberculosis programmes should collaborate to address this health crisis with comprehensive strategies, including decarceration.

Mass incarceration as a driver of the tuberculosis epidemic in Latin America and projected impacts of policy alternatives: A mathematical modeling study

Background

Tuberculosis incidence is increasing in Latin America, where the incarcerated population has nearly quadrupled since 1990. The full impact of incarceration on the tuberculosis epidemic, accounting for effects beyond prisons, has never been quantified.

Methods

We calibrated dynamic compartmental transmission models to historical and contemporary data from Argentina, Brazil, Colombia, El Salvador, Mexico, and Peru, which comprise approximately 80% of the region's incarcerated population and tuberculosis burden. Using historical counterfactual scenarios, we estimated the transmission population attributable fraction (tPAF) for incarceration and the excess population-level burden attributable to increasing incarceration prevalence since 1990. We additionally projected the impact of alternative incarceration policies on future population tuberculosis incidence.

Findings

Population tuberculosis incidence in 2019 was 29.4% (95% UI, 23.9-36.8) higher than expected without the rise in incarceration since 1990, corresponding to 34,393 (95% UI, 28,295-42,579) excess incident cases across countries. The incarceration tPAF in 2019 was 27.2% (95% UI, 20.9-35.8), exceeding estimates for other risk factors like HIV, alcohol use disorder, and undernutrition. Compared to a scenario where incarceration rates remain stable at current levels, a gradual 50% reduction in prison admissions and duration of incarceration by 2034 would reduce population tuberculosis incidence by over 10% in all countries except Mexico.

Interpretation

The historical rise in incarceration in Latin America has resulted in a large excess tuberculosis burden that has been under-recognized to-date. International health agencies, ministries of justice, and national tuberculosis programs should collaborate to address this health crisis with comprehensive strategies, including decarceration.

Generalized Resistance Deficits in inmates with hypertension: missing resources that limit health

OBJECTIVE

to understand the Generalized Resistance Deficits of people deprived of liberty with hypertension in a Brazilian prison unit.

METHOD

qualitative research, anchored in Salutogenesis, carried out with 38 people with hypertension from a Brazilian prison unit, from February to July 2022, with a semi-structured interview with open-ended questions, whose analysis was thematic, explaining the limitations to health in prison.

RESULTS

13 Generalized Resistance Deficits were reported, mostly related to the prison environment and, to a lesser extent, to the social group and the individual, respectively. Living in prison for people with hypertension implies living with a high number of Generalized Resistance Deficits, accentuating the movement towards the disease pole.

FINAL CONSIDERATIONS

knowing Generalized Resistance Deficits allows directing health promotion to support the use of available Generalized Resistance Resources and contributes to the expansion of intersectoral policies.

Differences in non-communicable diseases between women in prison and the general population in Brazil

Women in prison have high risk for non-communicable diseases both in relation to men in prison and in relation to women in the general population. This study documented the health disparities related to diseases among women in prison and in the general female population in Brazil. Women in prisons (WP) < 30 years old had a prevalence of hypertension (PR = 4.5; 95% CI 3.4-6.1), cardiovascular disease (PR = 4.4; 95% CI 2.4-7.9) and asthma (PR = 3.0; 95% CI 2.3-3.8) higher than general female population in Brazil in the same age group. Women in prison > 50 years old also presented asthma prevalence (PR = 4.3; 95% CI 2.9-6.3) higher than the general female population in Brazil in the same age group. These women in prison, overwhelmingly young, could be mistaken for an elderly population in Brazil. Actively responding to early disease in these women can reduce overall health costs and improve health care for this population that may have limited access to health care outside of prison.

Health of female prisoners in Brazil

Abstract The majority of the women in prisons comes from the poorest strata of society with limited access to education, income and health services. This contributes to the fact that female prisoners have a higher burden of adverse health events than both male prisoners and women in general population We objectived to estimate the prevalence of different morbidities and risk factors among female prisoners in Brazil. A total of 1,327 women were recruited in this cross-sectional study. Data were collected using a using audio computer-assisted self-interviewing questionnaire, rapid antibody tests and physical examination. The higher prevalences was of syphilis, infection sexually disease, arterial hypertense, asthma, common mental disorders and severe physical violence. Regarding risk factors, 36.3% have good knowledge about HIV, 55.8% were smokers, 72.3% had ever used any illicit drug, 92.1% are sedentary and 92.1% maintained an unhealthy diet. Female prisoners are disproportionately affected by various adverse health conditions. There is a need for an effective surveillance system inside prisons for early diagnosis and treatment.

Abundance of undiagnosed cardiometabolic risk within the population of a long-stay prison in the UK

BACKGROUND

The health of people in prisons is a public health issue. It is well known that those in prison experience poorer health outcomes than those in the general community. One such example is the burden of non-communicable diseases, more specifically cardiovascular disease (CVD), stroke and type 2 diabetes (T2DM). However, there is limited evidence research on the extent of cardiometabolic risk factors in the prison environment in Wales, the wider UK or globally.

METHODS

Risk assessments were performed on a representative sample of 299 men at HMP Parc, Bridgend. The risk assessments were 30 min in duration and men aged 25-84 years old and free from pre-existing CVD and T2DM were eligible. During the risk assessment, a number of demographic, anthropometric and clinical markers were obtained. The 10-year risk of CVD and T2DM was predicted using the QRISK2 algorithm and Diabetes UK Risk Score, respectively.

RESULTS

The majority of the men was found to be either overweight (43.5%) or obese (37.5%) and/or demonstrated evidence of central obesity (40.1%). Cardiometabolic risk factors including systolic hypertension (25.1%), high cholesterol (29.8%), low HDL cholesterol (56.2%) and elevated total cholesterol: HDL ratios (23.1%) were observed in a considerable number of men. Ultimately, 15.4% were calculated at increased risk of CVD, and 31.8% predicted at moderate or high risk of T2DM.

CONCLUSIONS

Overall, a substantial prevalence of previously undiagnosed cardiometabolic risk factors was observed and men in prison are at elevated risk of cardiometabolic disease at a younger age than current screening guidelines.
