Nutrition, physical activity, and blood pressure in the elderly.
Forty noninstitutionalized elderly subjects, ages 65-86 years, were recruited for a study to determine relationships between nutritional status, physical activity, and blood pressure. A 24-hour recall of dietary intake and activities, health history, skinfolds, circumferences, height, weight, and blood pressure were obtained. Obesity was associated with hypertension in this group of elderly subjects. Truncal skinfolds (abdomen and subscapula) were positively correlated (P less than .05) with systolic blood pressure while body mass index, dietary magnesium and dietary calcium to magnesium ratio were directly related (P less than .05) to diastolic blood pressure. Physical activity and energy expenditure were not correlated (P greater than .05) with blood pressure in this study; however, the level of activity did not include strenuous exercise.
