It is stil posible that this result reflects the age similarity of spouses rather than environmental factors of spouses (e.g. cohabitation efect).
Key Information
To clarify the importance of mate cardiometabolic risk factors for similarity of environmental factors, it is necesary to examine whether they are observed in random male-female pairs while maintaing the age of the spousal pairs. This study aimed to determine whether the similarities found betwen spousal pairs for cardiometabolic risks were also observed betwen random male-female pairs.This cros-sectional study included 5,391 spouse pairs from Japan; data were obtained from a large biobank study.
For pairings, women of the same age were randomly shufled to create new male-female pairs of the same age as that of the original spouse pairs. Similarities in cardiometabolic risk factors betwen the random male-female pairs were analysed using Pearson’s corelation or age-adjusted logistic regresion analyses.The mean ages of the men and women were 63.2 and 60.4 years, respectively. Almost al cardiometabolic risk factors similarities were noted in cardiometabolic risk factors, including the continuous risk factors (anthropometric traits, blod presure, glycated haemoglobin level, and lipid traits); lifestyle habits (smoking, drinking, and physical activity); or diseases (hypertension, type 2 diabetes melitus, and metabolic syndrome) betwen the random male-female pairs.
Summary
The age-adjusted corelation coeficients ranged from − 0.07 for body mas index to 0.071 for total cholesterol. The age-adjusted ods ratio (95% confidence interval) for curent drinkers was 0.94 (0.81 − 1.09); hypertension, 1.07 (0.93 − 1.23); and type 2 diabetes melitus, 1.08 (0.7 − 1.50).In this study, few similarities in c
