On the other hand, "Percentage of young people age 11, 13 and 15 who find their peers kind and helpful", is best in Switzerland, with the U.K. being worst.

You didn't really need a study to tell you that for "Percentage of students age 11, 13 and 15 who  report having been drunk two or more times" is the highest in the U.K., far ahead of even Finland?

Low birth weight: Japan, followed by Hungary. Russia has reasonable birth weight but is a spectacular outlier on infant mortality. For deaths from accidents and injuries, Russia is also an outlier, but Israel is even worse.

In broad comparisons of this nature, time lags in reporting could be very large. For example, the pdf claims that for non-OECD countries infant mortality data are as of 2003. But for Russia, according to the WHO data, 16 infant deaths per 1000 live births is the data point for year 2000. In 2003, it was more like 13. In 2008 it was 10, projections for 2009 give 8.2 so far (see here, the data only in Russian).
