Jewish denominations and longevity.

This study examined the relationship between affiliation with one of three denominations within Judaism representing a conservative-liberal continuum of Orthodox, Conservative, and Reform Judaism. The criterion for affiliation was burial in a cemetery maintained by these denominations. Longevities of married congregants born 1850-1910 were compared, controlling for birth year. Orthodox Jews had the shortest life spans (77 years); Conservative and Reform Jews had very similar life spans (80.7 years). Differences in years of survival of husbands after death of a spouse did not differ significantly. Reform widows survived longest (16.5 years) after death of a spouse. Conservative and Reform widows did not differ significantly from one another.
