ITHACA, N.Y. -- Although high school women are more concerned about their weight than men are about theirs, the women are more willing than men to date an overweight person. Once married, obese husbands are less happy with their marriages than other men, but men who have lost weight report fewer marital problems than obese or average-weight men or men who have gained weight during marriage. Obese wives, on the other hand, are happier with their marriages than average-weight wives. While newly-married women gain more weight than other wives do, or men do proportionately, few gain a lot during their first year of marriage. These are some of the recent findings of Jeffery Sobal, a Cornell nutritional sociologist who studies the sociology of obesity and the relationship between obesity and dating, marriage and marital satisfaction.
