Our systematic review of rural/urban differences in #TB prevalence shows evidence of rapidly urbanising epidemics in many settings, with differences across countries and regions. Link to preprint below ⬇️

Are there more people with #TB in cities or rural areas? In a 🚨new🚨 preprint (NOT PEER REVIEWED) we modelled urban-rural TB trends from 2000-2023 in 26 countries with 4.6 billion people. www.medrxiv.org/content/10.1...

Men are more than twice as likely as women to have prevalent #TB. We did updated meta-analysis including over 4million people in 99 surveys. Despite increasing focus on gender equitable TB responses, this gap has widened since we last assessed these data over a decade ago.

6/ @petermacp.bsky.social and I seem to be the only coauthors on Bluesky, but this work comes from a great team across @hsph.harvard.edu @uofglasgow.bsky.social @tb-lshtm.bsky.social @lshtm-tbmod.bsky.social

5/ These findings show that, despite calls for gender responsive TB prevention and care, disparities have increased over the past three decades. Effective strategies to reduce men’s risk of TB and to engage men in TB prevention and care remain essential to end TB. NOT PEER REVIEWED

4/ The stability of pooled estimates doesn't mean sex ratios have remained consistent. We found evidence that male-to-female ratios likely increased 1.6% (95% CrI -1.0-6.2%) annually over the period 1994–2021, with the greatest increase in the Western Pacific region. NOT PEER REVIEWED

3/ We fitted multi-level Bayesian regression models to estimate a pooled male-to-female prevalence ratio of 2.21 (95% CrI 1.94-2.50) for bacteriologically-confirmed TB. That's the same point estimate as our previous review, but the two studies used different analytical methods. NOT PEER REVIEWED

2/ We updated our systematic review and identified 99 TB prevalence surveys reporting sex-disaggregated results (with >4 million participants) conducted between 1993 and 2024 in 33 low- or middle-income countries. NOT PEER REVIEWED

1/ It’s been 10 years (😮) since we reported that #TB prevalence was twice as high in men as in women. 📢 Our new preprint explores how sex differences have shifted with more recent national prevalence surveys and growing attention to #gender responsive TB prevention and care. bit.ly/4gqP1LH

New systematic review led by @hannahrickman.bsky.social shows annual risk of Mycobacterium #tuberculosis conversion in men and women diverges during adolescence and remains higher among men throughout adulthood. www.thelancet.com/journals/lan...

NEW STUDY! 📣 A large global study found men are more likely to be exposed to TB than women. The reason? Likely social behaviours: • More time in crowded indoor spaces • Delays in seeking care READ MORE ⤵️ 🔗 www.thelancet.com/journals/lan... @petermacp.bsky.social @hannahrickman.bsky.social

Brilliant analysis that reinforces the need for concerted efforts to address gender-related barriers to TB diagnosis and treatment for men and adolescent boys. Essentially, men are more likely to acquire TB because they are more likely to be exposed to other people (mostly men) with TB.

In meta analysis of data from nearly half a million people, we found that men have higher M. #tuberculosis immunoreactivity risk than women. Likely to be key driver of sex differences in global tuberculosis morbidity & mortality @hannahrickman.bsky.social 🛟🧪 authors.elsevier.com/sd/article/S...

In the 1980s, many thought tuberculosis was on the path to elimination. In reality, more were dying from the disease than ever. The second article in our series on Tuberculosis: ourworldindata.org/the-end-of-t...

Tuberculosis still kills around 1.3 million people every year. It was once a massive killer in Europe and the US, but not anymore. How did these countries manage to tackle it? Our first article on TB in a three-part series: ourworldindata.org/tuberculosis...

Amid all the bad news in Global Health, perhaps some good news? A first analysis on the risk of false positive diagnoses in community-screening for tuberculosis using Xpert shows our clinic-based data is likely (very) wrong and overestimates false positives by >80%: tinyurl.com/yfecute9.

#Tuberculosis prevention and care relies heavily on international donor funding in many settings. In our latest preprint, we examine the potential impact of reductions in international donor funding for #TB - by the US and by other major donor countries. 1/8 www.medrxiv.org/content/10.1...

New pre-print modelling impact of US funding cuts on HIV, #TB, MCH and family planning. We estimate impact of termination of US funding to NTPs via #USAID & The Global Fund may lead to 2.2 (1.5-2.9) million excess TB deaths between 2025 and 2040, reversing over a decade of progress. bit.ly/4lowp18

Our latest pre-print led by @alexandra-richards.bsky.social shows that improving #TB treatment coverage among men to the level achieved among women could reduce morbidity and mortality in men, women, and children. Further evidence of the need for gender-responsive TB prevention and care!

congrats Peter and team

Very nice analysis showing both potential and challenges of molepi in TB, having to work with samples from small fraction of TB episodes. Highly recommend the read, interesting data and thoughts for debate of targeted vs community-wide screening. But clearly a massive lift by the team, congrats!
