Association of Restraint Scale scores with BMI and weight change among 1,587 individual twin participants

	BMI^a			Weight change^b
	Mean^c kg/m²	95% CI	P value^d	Mean^c pounds	95% CI	P value^d
Restraint Scale Score category			<0.001			<0.001
High (>16)	27.9	(27.4–28.4)		6.9	(5.4–8.4)
Intermediate (12≤16)	25.5	(25.2–25.8)		4.9	(4.1–5.6)
Low (≤11)	23.0	(22.7–23.3)		2.8	(1.8–3.8)

CI, confidence interval.

Adjusted for age, gender, education, race, smoking history, and physical activity.

Adjusted for age, gender, education, race, smoking history, initial BMI, and time elapsed between self-reported weights.

Means are adjusted least squared means.

P values are from linear regression using general estimating equations with robust s.e.
