The finding that young women consistently exercised less than young men, suggests that differences in energy expenditure could play a role in gender disparities in obesity and overweight.
The frequency of eating fruit and vegetables remained relatively stable among young adult women but declined significantly among young men. Young men also reported eating breakfast less often than did young women.
Both men and women reported a steady decline in the frequency of getting at least seven hours of sleep each night.
Despite the focus on television viewing as an important determinant of obesity, the researchers found that the amount of time men and women spent watching TV stayed relatively stable.
When the researchers compared behaviors of different racial and ethnic groups, they found some major differences. For example, although white women showed a steady increase in the frequency of eating breakfast, the trajectory for non-Hispanic black women declined until 1996 and only began to increase in 2000.
Although fruit and vegetable consumption changed little among young adults, consumption of both was consistently lower among black and Hispanic men and women in any given year.
And although the frequency of exercise remained relatively stable among young adult women in general, among black women, the frequency of exercising steady declined.
In addition, black and Hispanic women showed greater declines than white women in the frequency of getting at least seven hours of sleep a night. They also were less likely than white women to report eating breakfast, and eating fruits and vegetables.
Among men, those from lower socioeconomic backgrounds reported dramatic declines in sleep, after adjusting for race and ethnicity.
Minority racial and ethnic groups, and women from lower socioeconomic groups, also reported watching television more often than
