Spousal similarities in 7-year changes in obesity and obesity-related phenotypes were examined in a subsample of 376 pairs of spouses from a sample of 1487 participants in the 1988 Campbell's Survey follow-up of the 1981 Canada Fitness Survey.
Indicators of body fatness included the body mass index (BMI), the sum of five skinfolds (SF5), and waist circumference (WAIST), whereas those for relative adipose tissue (AT) distribution included the ratio of two trunk to three extremity skinfolds, adjusted for SF5 (TERadj), and WAIST adjusted for BMI (WAISTadj).
Spouse correlations were 0.17, 0.17, and 0.17 for the BMI (p
