Gay life expectancy revisited
Bibliographic record
Abstract
Over the past few months we have learnt of a number of reports regarding a paper we published in the International Journal of Epidemiology on the gay and bisexual life expectancy in Vancouver in the late 1980s and early 1990s.1 From these reports it appears that our research is being used by select groups in US2 and Finland3 to suggest that gay and bisexual men live an unhealthy lifestyle that is destructive to themselves and to others. These homophobic groups appear more interested in restricting the human rights of gay and bisexuals rather than promoting their health and well being. The aim of our research was never to spread more homophobia, but to demonstrate to an international audience how the life expectancy of gay and bisexual men can be estimated from limited vital statistics data. In our paper, we demonstrated that in a major Canadian centre, life expectancy at age 20 years for gay and bisexual men is 8 to 21 years less than for all men. If the same pattern of mortality continued, we estimated that nearly half of gay and bisexual men currently aged 20 years would not reach their 65th birthday. Under even the most liberal assumptions, gay and bisexual men in this urban centre were experiencing a life expectancy similar to that experienced by men in Canada in the year 1871. In contrast, if we were to repeat this analysis today the life expectancy of gay and bisexual men would be greatly improved. Deaths from HIV infection have declined dramatically in this population since 1996. As we have previously reported there has been a threefold decrease in mortality in Vancouver as well as in other parts of British Columbia.4 It is essential to note that the life expectancy of any population is a descriptive and not a prescriptive mesaure.5 Death is a product of the way a person lives and what physical and environmental hazards he or she faces everyday. It cannot be attributed solely to their sexual orientation or any other ethnic or social factor. If estimates of an individual gay and bisexual man's risk of death is truly needed for legal or other purposes, then people making these estimates should use the same actuarial tables that are used for all other males in that population. Gay and bisexual men are included in the construction of official population-based tables and therefore these tables for all males are the appropriate ones to be used. In summary, the aim of our work was to assist health planners with the means of estimating the impact of HIV infection on groups, like gay and bisexual men, not necessarily captured by vital statistics data and not to hinder the rights of these groups worldwide. Overall, we do not condone the use of our research in a manner that restricts the political or human rights of gay and bisexual men or any other group.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
