Participant flow diagram through a 1-year randomized controlled trial of weight gain prevention using registered dietitian-led (RDG) or counselor-led (CSG) nutrition education or control (CON) groups.

^aReasons for withdrawal in RDG: family emergency (n=1 before baseline testing, n=1 before month 3 testing, n=2 before month 12 testing), lost to follow up (n=2 before baseline testing, n=1 before month 6 testing, n=1 before month 12 testing), moved out of the area (n=6 before month 12 testing), pregnancy (n=1 before month 9 testing, n=1 before month 12 testing), time (n=2 before month 3 testing); 1 participant in the RDG did not attend the month 6 testing session due to a family emergency, but completed all remaining testing sessions; 1 participant in the RDG did not attend the month 9 testing session due to a family emergency, but completed all remaining testing sessions.

^bReasons for withdrawal in CSG: lost to follow up (n=1 before month 6 testing, n=1 before month 12 testing), moved out of the area (n=1 before month 9 testing, n=2 before month 12 testing), personal health issues (n=1 before month 9 testing), time (n=4 before month 3 testing), uncomfortable with study (n=1 before month 3 testing), undisclosed (n=1 before month 3 testing), Zung >50 (n=1 before month 12 testing).

^cReasons for withdrawal in CON: family issues (n=1 before month 12 testing), moved out of the area (n=1 before month 12 testing), pregnancy (n=1 before month 6 testing), time (n=3 before baseline testing, n=1 before month 3 testing), Zung >50 (n=1 before month 6 testing); 3 participants in the CON did not attend month 9 testing (illness n=2, time n=1), but returned for month 12 testing
