Forty-two female patients with refractory obesity completed a 20-week double-blind study during which they were given a diet designed to provide not more than 40 mg vitamin C and 1000 kcal (4.2 MJ) daily. Twenty-two of the patients took 600 mg of supplementary vitamin C daily and the remainder, a matched placebo. All were given their highest tolerated dose of fenfluramine up to a maximum of 160 mg daily. There was no significant difference in the mean weight loss of the two groups. This study fails to support the hypothesis that the anti-obesity effect of fenfluramine is influenced by the vitamin C intake.

Following initial weight gain, reduction in appetite and pronounced weight loss occurred in scorbutic unsupplemented guinea-pigs. Hepatic ascorbic acid levels were significantly reduced and cholesterol concentration increased in the liver. Fenfluramine administration caused immediate loss of weight and appetite in the scorbutic guinea-pigs, these changes being more pronounced in the males. Hepatic ascorbic acid, cholesterol and triglycerides were reduced to lower levels in the fenfluramine-treated scorbutic animals than in the scorbutic guinea-pigs receiving diet alone. In contrast, weight and appetite increased in vitamin-C-supplemented animals while they were receiving fenfluramine. Their hepatic cholesterol and triglyceride levels became significantly reduced. It has been shown that supplementary vitamin C can inhibit the anti-obesity and anorectic actions of fenfluramine and counteract its effect in raising tissue cholesterol.

Nutritional assessment of white persons over 59 who participated in the 1973 Missouri Nutrition Survey was based upon biochemical measurements, dietary intakes using food frequency histories, anthropometric measurements, and a dental examination. There were three major nutritionally related problems: poor dental health, obesity, and anemia. The mean for DMF, periodental index, and oral hygiene index for males was 20.5, 4.9, and 3.9, respectively; for females, 17.6, 3.6, and 2.5. Over one-half of both sexes were edentulous. Of the women 59% were greater than 119% of desirable weight compared to 22% of the men. Using guidelines from the Ten-State Nutrition Survey, the following percentages of men had low blood levels: 20, hemoglobin and serum iron; 2, plasma vitamin A; 6, plasma carotene; 1, serum vitamin C; and 0, serum albumin. The percent of women with low biochemical levels were: 11, hemoglobin; 10, serum iron; 7, plasma vitamin A; 1, serum vitamin C; and 2, serum albumin. None of the subjects had low or deficient levels of erythrocyte glutathione reductase. One-half of the women compared to one-fifth of the men had consumed diets with one or more nutrients below 67% of the 1974 Recommended Dietary Allowances.

Cognitive changes, depression, arthralgia and dermatitis developed in a 33-year-old woman 5 years after a jejunoileal shunt for massive obesity, The dermatitis and low serum carotene and vitamin C values suggested vitamin deficiencies, The serum magnesium concentration also was low. Vitamin and mineral replacement led to amelioration of the physical and psychological symptoms; the improvement has been maintained at 18-month follow-up. The favourable changes were documented with the Wechsler Adult Intelligence Scale, the Minnesota Multiphasic Personality Inventory and test performance ratings. It is concluded that the surgical procedure caused vitamin and magnesium deficiencies and that these resulted in the patient's symptoms.

The present study analyzes the influence of the nutritional status on the functional capability of 11 institutionalized elderly living in Madrid (Spain). Nutritional status was evaluated by dietetic, anthropometric, hematological and biochemical data and functional status was evaluated considering adiposity, strength in hands and legs bent and stretched and flexibility. The most important nutritional problems that conditional functional wastages are obesity, hypercholesterolemia and protein and micronutrient deficiency. The adverse influence of obesity and hypercholesterolemia on the functional capacity of the elderly is shown by the inverse relationship between flexibility and strength in hands and legs with the adiposity degree, with the thickness of skin folds and the cholesterolemia. In reference to the diet's influence, there are positive correlations between food intake and most of the nutrients with hand and legs strength, and there are statistical significances for proteins, iron, zinc, magnesium and pyridoxine, and also for vitamin C, niacin, thiamin, folic acid and vitamin E. For blood values, the mayor correlation exists between functional parameters and iron, ferritin and vitamin C levels. Our results contribute to confirm the influence of nutrition on the functional capacity of the influence of nutrition on the functional capacity of the elderly and manifest the necessity of improving the elderly's diet, to prevent micronutrient deficiency and also the necessity of increasing their physical activity. Both measures will mean an important help for sanitary and functional improvement of the elderly.

The dietary habits of 1265 men and 1309 women aged 35-64 years were assessed by food frequencies and 24-h recall. The consumption of fat was high relative to Recommended Dietary Allowances (mean 137% of RDA in the diet of men and 108% in women). The diet was deficient in carbohydrates (80 and 67% respectively), calcium (81 and 64%), vitamin A (84% for both sexes), vitamin B1 (91 and 74%), and vitamin C (41 and 30%). Energy, protein, dietary fibre, iron and vitamin B2 were at the RDA or exceeded it in the men's diet but were insufficient in the women's diet. Fat accounted for 38.5% (men) and 37.7% (women) of energy, with 15.8% of the energy derived from saturated fatty acids and 4.2% from polyunsaturates. The amount of cholesterol consumed was 641 and 452 mg, respectively. This type of diet may contribute to increased incidence of ischaemic heart disease. Only three meals a day were taken by over 83% of the respondents, with over 5-h intervals between meals which may, in addition, contribute to obesity.

In order to learn about the influence of dietary factors and obesity on prostatic cancer in our environment, a case-control study was performed. The group of cases consisted of 90 men histologically diagnosed with prostatic cancer in the 'La Paz' hospital (Madrid) during the 4-year period of 1983-1987. The controls were 180 men selected to obtain a random sample of males from the same hospital, stratified according to age and date of admission as compared with the prostatic cancer patients. The results of the study revealed that a diet rich in animal fats as well as high in meat consumption increased the risk of prostatic cancer. Low ingestion of vitamin A or vitamin C and obesity were unassociated to the disease.

Resting metabolic rate and its relation with selected anthropometric measures was determined in 11 male and 7 female noninstitutionalized children with Down syndrome. Dietary analysis was performed to determine the nutritional status of the children and whether poor nutritional habits may be influencing factors in the development of obesity in this population. Resting metabolic rate for the total group was 170.4 +/- 38.65 ml.min-1 (0.17 +/- 0.04 ml.kg-1.min-1). Body weight, height, and surface area were moderately correlated with this rate, with height having the strongest relation. Daily caloric intake was 1,433.84 +/- 255.2 calories, comprising of 16.01 +/- 2.20% protein, 42.18 +/- 7.40% fat, and 40.60 +/- 8.83 carbohydrate. Calcium, potassium, and vitamin C were above and iron and thiamine below the recommended daily allowance.

Age-related cataract is a condition characterized by multiple mechanisms and multiple risk factors. The mechanisms that bring about a loss in transparency include oxidation, osmotic stress, and chemical adduct formation. Risk factors for cataract include diabetes, radiation (ultraviolet B, x-ray), certain pharmaceutical substances, certain nutritional states, and possibly acute episodes of dehydration. Interaction occurs between and among mechanistic factors and risk factors. Thus nutrition must be considered as one part of a tapestry of intertwined events and responses. Certain experimental models for nutritional cataract have been useful for study of the cataractogenic process but are probably not important factors in the human disease. Little current evidence supports significant roles in human senile cataract for imbalances of tryptophan or other amino acids, deficiencies of calcium or selenium, or excessive intake of selenium. Overconsumption of galactose is likely to be hazardous only in subjects with genetic inability to metabolize this sugar. Vitamins with antioxidant potential (riboflavin, vitamin E, vitamin C, carotenoids) deserve further research scrutiny to ascertain their significance in cataract etiology. Excessive caloric intake needs to receive added emphasis as a factor contributing to cataract. Diabetes increases the likelihood of cataract three- to four-fold. Obesity, defined as more than 20% overweight, is considered a major risk factor for non-insulin-dependent, or type II, diabetes (69, 73). Weight control can be recommended as a prudent, safe, economic, and effective means of lowering risk probability for diabetes and the associated complication of cataract.

A large cross sectional study, the Scottish Heart Health Study, of 10,359 men and women from 22 districts of Scotland was undertaken to try to explain the geographical variation of coronary heart disease mortality. Analysis by district showed that of the classic risk factors only cigarette smoking was strongly associated with heart disease mortality among both men and women. Mean diastolic blood pressure was weakly associated with rates among men and high density lipoprotein cholesterol showed a strong negative association among women. Total cholesterol showed a weak negative association with heart disease mortality, but, because the serum concentrations of cholesterol were uniformly high in all districts, a strong association with mortality would not be expected. In both men and women many dietary factors showed moderate or strong associations with mortality from coronary heart disease in a district--of these a low consumption of vitamin C was most notable. Other factors associated with heart disease included alcohol consumption and serum triglycerides among men, and obesity, physical activity, and serum triglycerides among women. Many factors associated with heart disease showed strong intercorrelations. Clustering of risk factors (including smoking, alcohol, and diet among men, and smoking, diet, and obesity among women) was associated with much of the regional variation in heart disease mortality in Scotland.
