How to survey set weights when combining multiple NHANES data

[Chinonso Odebeatu]

Please, can someone familiar with NHANES dataset help me with how to survey set weights when combining more than one cross sectional NHANES wave. I am trying to use three cross-sectional wave for my analysis: 2007-2008, 2009-2010, and 2011-2012. how do I set thw weights given that each year has its own sampling weights, strata and primary sampling units.

See the section on combining survey cycles on page 7 of this document, which is very similar to the examples in this web tutorial.
