Health inequalities are worsening in the North East of England.

BACKGROUND: The North of England, particularly the North East (NE), has worse health (e.g. 2 years lower life expectancy) and higher health inequalities compared to the rest of England. SOURCES OF DATA: We explore this over time drawing on publicly available data. AREAS OF AGREEMENT AND CONTROVERSY: Whilst overall health is improving, within-regional health inequalities are getting worse and the gap between the NE and other regions (particularly the South of England) is worsening. The gap in life expectancy is widening with substantial variation between deprived and affluent areas within the NE. Those living in the NE are more likely to have a shorter lifespan and to spend a larger proportion of their shorter lives in poor health, as well as being more likely to die prematurely from preventable diseases. GROWING POINTS: We highlight wide, and in some cases increasing, inequalities in health outcomes between the NE and the rest of England. This health disadvantage and the north-south health divide are recognized; despite this, the situation appears to be worsening over the time. AREAS TIMELY FOR DEVELOPING RESEARCH: Research to understand and reduce health inequalities is needed particularly in the NE of England where reductions could have enhanced the impact.

Quantifying the association between tuberculosis and diabetes in the US: a case-control analysis.

Historically, an association between tuberculosis and diabetes was recognised clinically, and the recent global rise in diabetes prevalence has reignited interest. We therefore quantified the tuberculosis-diabetes association using US survey data. A case-control analysis was performed using cross-sectional data from the second National Health and Nutrition Examination Survey (1976-1980; civilian non-institutionalised US population aged 20-74). Cases were respondents ever diagnosed with tuberculosis, and controls were respondents who reported never receiving a tuberculosis diagnosis. Exposure to diabetes and intermediate hyperglycaemia was defined using a self-reported measure, an oral glucose tolerance test, or both. We used logistic regression to estimate an adjusted odds ratio, controlling for potential major confounders. In relation to the main exposure measure, the adjusted odds ratio for the association between tuberculosis and diabetes varied between 2.31 (95% confidence interval 1.36-3.93) and 2.36 (95% confidence interval 1.40-3.97), depending on the model. No association was found for intermediate hyperglycaemia, with adjusted odds ratio varying between 1.33 (95% confidence interval 0.49-3.64) and 1.34 (95% confidence interval 0.50-3.62), depending on model. Irrespective of the exposure measure and the confounders controlled for, diabetes was associated with an increased tuberculosis risk. This study may underestimate the true association due to exposure misclassification.
