Multinomial Logistic Regression Models: The Whitehall II Study, London, UK, 1985–1999

Exposure to Negative Aspects of Close Relationships	Recommended Healthy Weight at Phase 3 to Overweight or Obese at Phase 5	Overweight at Phase 3 to Recommended Healthy Weight at Phase 5 or Obese at Phase 3 to Overweight or Recommended Healthy Weight at Phase 5	Overweight at Both Phases or Obese at Both Phases	Overweight at Phase 3 to Obese at Phase 5
Complete cases
Mean score, OR (95% CI)	1.02 (0.97, 1.08)	0.96 (0.86, 1.07)	1.00 (0.96, 1.04)	1.06 (0.98, 1.14)
P (No.)	.4 (431)	.46 (106)	.95 (1218)	.13 (205)
Imputed sample
Mean score, OR (95% CI)	1.02 (0.99, 1.06)	1.00 (0.94, 1.07)	1.01 (0.99, 1.04)	1.05 (1.00, 1.10)
P (No.)	.22 (1349)	.96 (389)	.32 (3659)	.04 (573)

Note. CI = confidence interval; OR = odds ratio. Body mass index (BMI) calculated by dividing weight in kilograms by height in meters squared. Recommended healthy weight (18.5 ≤ BMI < 25) at both phases (n = 1233 in complete cases and n = 3333 in imputed sample) was used as a reference category. Overweight was defined as 25 ≤ BMI < 30; obese was defined as a BMI≥30. Those considered underweight (BMI < 18.5 at phase 3 or phase 5) were excluded from the analysis (n = 43 in complete cases). Adjusted for gender, age, marital status, and ethnicity.
