Hazard Ratios for Incident Obesity Among 2,913 Women Who Were Not Obese at Baseline^a, by Change in Husband's Obesity Status, 1987–2013

Model	Husband's Obesity Status

Abbreviations: CI, confidence interval; HR, hazard ratio.

^a A total of 518 women became obese by visit 5.

^b The n values represent the number of observations, that is, the change (or lack of change) in husbands' obesity statuses between 2 visits. Because spouse pairs were usually included for more than 2 visits, the total number of observations (7,637) is greater than the number of spouse pairs in the analysis (2,913). The percent of observations for each category is 74.9% for stable nonobese, 6.1% for nonobese to obese, 2.9% for obese to nonobese, 16.6% and for stable obese.

^c Model 1 includes baseline body mass index.

^d Model 2 includes baseline body mass index, race, study site, employment, educational level, smoking status, calorie intake, cardiovascular diet score, alcohol intake, leisure and sport physical activity scores, coronary heart disease, hypertension, diabetes, cancer, and lung disease for both the individual and her spouse.
