Latent classes of behavioral response to PREMIER lifestyle interventions: behavioral response patterns

	Responders (n=230, 45.9 %)		Early adherers (n=153, 30.5 %)		Non-responders (n=118, 23.6 %)
	Baseline	6 months	Baseline	6 months	Baseline	6 months
Sodium ≤2300 mg/day	No (p=.19)	Yes (ρ=.64)	No (p=.38)	Yes (ρ=.72)	No (p=.15)	No (p=.37)
Fat ≤30 % of total energy	No (p=.05)	Yes (ρ=.98)	Yes (ρ=.89)	Yes (ρ=.81)	No (p=.06)	No (p=.00)
Saturated fat ≤10 % of total energy	No (p=.19)	Yes (ρ=.93)	Yes (ρ=.91)	Yes (ρ=.78)	No (p=.13)	No (p=.22)
≥5 servings of fruit and vegetables/day	No (p=.31)	Yes (ρ=.72)	Yes (ρ=.52)	Yes (ρ=.75)	No (p=.30)	No (p=.35)
180 min/week of moderate physical activity	No (p=.36)	Yes (ρ=.61)	No (p=.46)	Yes (ρ=.71)	No (p=.37)	No (p=.49)

Rho (ρ) is the item-response probability (i.e., probability that recommendation is met at given time point for the given latent class). Rho (ρ)>0.5 indicates high probability of meeting recommendations (<0.5 indicates low probability of meeting recommendations). No covariates were included in this repeated measures latent class model
