Nutritional knowledge questionnaire. Part two.

An easily administered and scored test of nutritional knowledge was published in the previous issue of the Journal (December 27, 1980). The correct answers to the questionnaire are presented here. The questionnaire has been administered to 2175 subjects. The test was shown to have high reliability and criterion validity, discriminating between educational and occupational groups. There was a significant linear relationship between nutritional knowledge score and age. It is suggested that the test may be of value in the assessment of patients requiring dietetic management.

The diet composition and nutritional knowledge of patients with anorexia nervosa.

A retrospective study of typical 24-h food intake was undertaken of the diets of 17 anorexia nervosa patients during the initial and the most severe phases of their illness. Patients completed a nutritional knowledge questionnaire. Patients' diets were significantly lower in energy and in all major nutrients than those of control subjects. The proportion of energy derived from protein was significantly higher, from fats significantly lower and from carbohydrates not significantly different from that of controls. The mean intake of all nutrients in the more severe phase of illness was lower in the initial phase. Intakes of calcium, retinol activity and ascorbic acid were below RDA levels in the majority of patients, but only a few reported intakes of thiamin, riboflavin and niacin equivalent below RDA values. Most patients scored higher on the nutritional knowledge questionnaire than matched controls, particularly in respect to questions concerning caloric content of food, dieting and roughage. Not all patients obtained high nutritional knowledge scores however, and 25 per cent performed less well than selected controls.

Quantitative evaluation of a home exercise program on muscle and functional capacity of patients with osteoarthritis.

Rehabilitation of patients with osteoarthritis of the knees is typically based on home exercise. These programs are believed to benefit patients and have been shown to qualitatively improve strength. The purpose of the present study was to quantify the effects of a 3-mo home exercise program on muscle function and functional capacity. The progressive program included flexibility, strength, endurance, active range of motion and functional activities. Nineteen subjects (67.4 +/- 7.5 yr) with osteoarthritis of the knees began the program, with only nine completing it. The subjects initially had significantly reduced muscle function and functional capacity. Maximal isometric strength of knee extension increased significantly at a knee flexion position of 45 degrees for hip flexion positions of 120 degrees and 60 degrees (35%); however, it failed to increase at longer muscle lengths. There were no significant improvements in hamstring strength. Maximal angular velocity improved after 3 mo of exercise (40%). Muscle endurance did not improve significantly. Although there was a slight increase in functional capacity, these data failed to demonstrate significant clinical or statistical improvement in overall function in patients after home exercise.
