1985 NHIS findings: nutrition knowledge and baseline data for the weight-loss objectives.

A nutrition objective for the nation is that, by 1990, 50 percent of the overweight population should have adopted weight regimens, balancing diet and physical activity. More than half of the overweight respondents in the 1985 National Health Interview Survey were trying to lose weight, and almost half of this group reported both increasing their physical activity and decreasing their intake of calories. Dietary restriction without exercise was the next most common weight-loss regimen, suggesting that educational efforts should emphasize the need to increase physical activity as part of appropriate weight-loss regimens. Attempts to lose weight were reported frequently among those of normal and lean weight as well as among those who were overweight, especially among women and the better educated. About one-fifth of already lean young women reported attempting weight loss, an indication that some inappropriate dieting is probably occurring, suggesting the need for caution in public health promotion of weight loss. Another 1990 objective is that 90 percent of adults should understand that eating fewer calories or increasing activity, or both, is essential to lose weight. More than 70 percent of adults in this survey were able to identify these as the two best ways to reduce weight, with greater proportions of the younger adults and the more highly educated being knowledgeable. The survey also provided data for an objective that targets some nutrition education and counseling as part of all routine health contacts with health professionals by 1990. Twenty-nine percent of all women and 22 percent of all men reported that eating proper foods was discussed sometimes or often in routine contacts.
