Persistence or Change in Leisure-Time Physical Activity Habits and Waist Gain During Early Adulthood: A Twin-Study
2014
Objective To determine the relationship between persistence or change in leisure‐time physical activity habits and waist gain among young adults. Methods Population‐based cohort study among 3383 Finnish twin individuals (1578 men) from five birth cohorts (1975‐1979), who answered questionnaires at mean ages of 24.4 y (SD 0.9) and 33.9 y (SD 1.2), with reported self‐measured waist circumference. Persistence or change in leisure‐time physical activity habits was defined based on thirds of activity metabolic equivalent h/day during follow‐up (mean 9.5 y; SD 0.7). Results Decreased activity was linked to greater waist gain compared to increased activity (3.6 cm, P < 0.001 for men; 3.1 cm, P < 0…
Effect of physical activity on health in twins: a 30-yr longitudinal study.
2010
Purpose: The aim of this study was to investigate whether persistent leisure-time physical activity, adjusted for genetic liability and childhood experiences, protects against chronic diseases, early signs of disability, and loss of life satisfaction. Methods: From 5663 healthy adult twin pairs, we identified 146 pairs who were discordant for both intensity and volume of leisure physical activity in 1975 and 1981. Of them, both members of 95 pairs were alive and participated in our follow-up study in 2005 when chronic diseases (such as diabetes, cardiovascular disease, and osteoarthritis), life satisfaction, and disability were assessed by a structured telephone interview. The mean age of t…
