Accounting for influencing factors when estimating suicide rates among US youth

September 13, 2019

Bottom Line: Using unadjusted suicide rates to describe trends may be skewed because they are affected by differences in age and year of birth. This secondary analysis of data included total population and suicide deaths by single year of age from 10 to 19 and by sex from 1999 to 2017 and accounted for those factors. Unadjusted suicide rates for females were 1.6 per 100,000 in 1999 and 3.5 per 100,000 in 2017, while adjusted rates that accounted for differences in age and year of birth increased from 1.7 per 100,000 in 1999 to 4.2 per 100,000 in 2017. Unadjusted rates for males were 7.4 per 100,000 in 1999 and 10.7 per 100,000 in 2017, while adjusted rates were 4.9 per 100,000 in 1999 and 8.7 per 100,000 in 2017. A limitation of the study is the use of data and coding in which the misclassification of suicide death cannot be completely ruled out.

Uncounted
First things first: our very own Latif Nasser has an exciting new show on Netflix. He talks to Jad about the hidden forces of the world that connect us all. Then, with an eye on the upcoming election, we take a look back: at two pieces from More Perfect Season 3 about Constitutional amendments that determine who gets to vote. Former Radiolab producer Julia Longoria takes us to Washington, D.C. The capital is at the heart of our democracy, but it's not a state, and it wasn't until the 23rd Amendment that its people got the right to vote for president. But that still left DC without full representation in Congress; D.C. sends a "non-voting delegate" to the House. Julia profiles that delegate, Congresswoman Eleanor Holmes Norton, and her unique approach to fighting for power in a virtually powerless role. Second, Radiolab producer Sarah Qari looks at a current fight to lower the US voting age to 16 that harkens back to the fight for the 26th Amendment in the 1960s. Eighteen-year-olds at the time argued that if they were old enough to be drafted to fight in the War, they were old enough to have a voice in our democracy. But what about today, when even younger Americans are finding themselves at the center of national political debates? Does it mean we should lower the voting age even further? This episode was reported and produced by Julia Longoria and Sarah Qari. Check out Latif Nasser's new Netflix show Connected here. Support Radiolab today at Radiolab.org/donate.
