The influence of change in marital status on weight change over one year

Marital status is an influence on body weight. Changes in marital status and body weight were examined in the National Survey of Personal Health Practices and Consequences, a telephone survey of 2,436 adults interviewed twice approximately 1 year apart. Two statistical methods for analyzing weight change were compared, and both produced similar results: regression analysis of weight change and regression analysis of weight at follow-up controlling for baseline weight. The findings revealed that women who entered marriage had greater weight change than women who remained married. Analysis of weight gain and weight loss separately showed that women who became married lost less weight than those who remained married. For men, there were no statistically significant relationships between marital change and weight change over a 1-year period. These findings support other literature showing that marital status plays a role in body weight changes. The results suggest gender differences may exist in the rate of body weight change after marriage, with more immediate changes in women than men.
