[Diet, smoking and reproductive history as risk factor for cervical cancer].

BACKGROUND: Epidemiological studies have suggested that smoking, nutrition and sexual patterns are major risk factors for cervical cancer. AIM: To study the association between food consumption patterns, smoking and sexual behavior and the risk of cervical cancer. MATERIAL AND METHODS: A matched case control study of 170 cases and 340 controls. Food and nutrient intakes were assessed by a food frequency questionnaire considering 58 antioxidant rich food items. Median daily intake of vegetables, fruits, antioxidant vitamins and fiber was calculated. A conditional logistic regression model was used to determine odds ratios associated with variations in nutritional intake and no nutritional factors (age at first delivery, parity, body mass index, family history of cancer and smoking). RESULTS: High intakes of vegetables, fruits, beta carotene, vitamin C, E and fiber were associated with a lower risk of cervical cancer (Odds ratios ranging from 0.56 to 0.78). The risk for cancer was inversely associated with the age at first delivery and directly associated with the total number of pregnancies and smoking. Multivariate analysis model showed a protective effect for vegetable and vitamin E consumption (odds ratio of 0.6 with confidence intervals of 0.5 to 0.8 p < 0.001) and a higher risk associated to smoking (odds ratio 2.8, confidence intervals 1.5-5.5 p < 0.002) and a younger age at the first delivery (odds ratio 3.37 confidence intervals 2-5.3 p < 0.001). CONCLUSIONS: Cervical cancer is associated with reproductive and food consumption behaviors. A higher intake of vegetables and foods rich in vitamin E can reduce its risk.

[Validation of global nutrition assessment in elders].

BACKGROUND: The Chilean Ministry of Health proposed the use of "Mini Nutritional Assessment", to identify elders at nutritional risk. This score considers anthropometric, dietary and quality of life items. AIM: To assess the concordance of the mini nutritional assessment with body mass index and dietary parameters in Chilean free living elders. MATERIAL AND METHODS: Subjects aged 70 years old or more, coming from four public outpatient clinics were studied. In all, the mini nutritional assessment, dietary intake using 24 h recalls and anthropometric parameters, were measured. Energy intake was evaluated using FAO/WHO/UNU guidelines. Micronutrient intake was evaluated using the Dietary Recommended Intakes (DRI) from USA. Kappa index was used to determine diagnostic concordance. RESULTS: Forty three percent of subjects were overweight or obese. There was a substandard intake of calcium, folate, zinc, vitamin A, C, E, B6, B12 and energy. Seventy nine percent of subjects had a deficient or regular food intake. Mini nutritional assessment score was normal in 66% of subjects. Fifty eight percent of those with a deficient food intake had a normal mini nutritional assessment. On the other hand, 73% of those considered at nutritional risk, had a normal or excessive weight. CONCLUSIONS: Mini nutritional assessment did not identify elders at nutritional risk in this sample.

[Breast cancer risk factors in women in Santiago, Chile].

BACKGROUND: Epidemiological studies suggest a relation between breast cancer, diet and life styles. AIM: To analyze the association between food patterns, obesity, smoking, alcohol consumption and breast cancer risk in women of Santiago. PATIENTS AND METHODS: A case-control study design (170 cases and 340 controls), matched by age and sex, was used. Through a food frequency questionnaire the average daily intake of vegetables, fruits, beta-carotene, vitamin A, C, E and fiber was analyzed. Other exposures to non-nutritional risks (parity, smoking, cancer history) were also studied. Conditional logistic regression was calculated to determine the odds ratio associated with variations in food and nutrient intake and non-nutritional factors. RESULTS: Cases had a greater BMI and a higher prevalence of obesity than controls (p < 0.02). No differences were observed in either group food patterns. The ORs for breast cancer associated with obesity and alcohol consumption were 1.65 (95% CI 1.06-2.64) and 1.61 (95% CI 1.06-2.54) respectively (p < 0.05). Multiparity had a protective effect with 0.66 less risk (95% CI 0.44-0.99). No protective effect associated to a greater intake of vegetables, fruits or natural antioxidants was observed. Multivariate analysis model disclosed obesity as a risk factor (OR 1.79, p < 0.02) and parity > or = 4 as protective (OR 0.62, p < 0.02). CONCLUSIONS: This study does not support a protective role for natural antioxidants against breast cancer but indicate a weak association with obesity.

[Food patterns among adults visiting primary care clinics in the metropolitan region].

AIMS: To assess the intake of foods and nutrients in a group of adults of the Metropolitan Region of Chile and to identify food intake patterns which may need to be modified according to the guidelines of health promotion. METHODS: A non-randomly selected group of 859 adults (410 men) from 120 health care centers of the National Health System (October 1995) was studied. Food intake was assessed by 24-hour recall applied by well-trained standardized nutritionists. Both frequency and food and nutrients intake were calculated. RESULTS: The mean age was 35.8 +/- 10.6 years old. Median energy, protein and fat intake in male were 2324 kcal, 84 g y 70 g, respectively. For women, medians intake were: 1668 kcal, 59 g and 53 g respectively. From the total sample 72%, 53% y 71% reported consumption of less than two servings of milk product, vegetables and fruits. Likewise 42%, 36% y 22% of subjects had calcium, vitamin A and C intake below than 50% of the corresponding recommended dietary allowances (RDA). On the other hand 24% of the sample had daily salt consumption higher than 5 g, 37% had energy intake derived from fat higher than 30% of total calories and 15% had more than 10% of the energy supplied by sugar. CONCLUSIONS: A significant part of the adult population had inadequate patterns of food intake which confirms the need to promote a healthier diet.

[Dietary carotene intake and lung cancer among men from Santiago].

Aiming to assess the association between carotenes and vitamin A intake and lung cancer, a case control study was performed. Sixty one male subjects with lung cancer and 61 controls paired for age, sex and smoking habits from 6 hospitals in Santiago were analyzed. Based on a consumption tendency enquiry, the mean weekly intake of food groups, carotenes and vitamin A was calculated, considering seasonal variations. Results showed that cases consumed less "winter" vegetables than controls (chard, beet, chicory, spinach and cabbage) but no differences between groups in carotene and retinol consumption. It is concluded that patients with lung cancer have a lower consumption of carotene rich vegetables.

[Malnutrition of the pregnant woman: an overestimated problem?].

The aim of this work was to compare the nutritional classification of pregnant women and their predictive value for low birth weight, using the criteria of the Ministry of Health (Rosso-Mardones curves) with the curves developed at the Department of Nutrition of the Faculty of Medicine and the body mass index. One thousand eight hundred four pregnant women of the Metropolitan Region, that were devoid of factors affecting birth weight, were studied retrospectively. Initial and final nutritional status was calculated according to the three criteria in study. Results showed that 47 to 75% of women classified as undernourished using Rosso-Mardones curves, were normal according to the curves of the Department of Nutrition and body mass index. Rosso-Mardones curves had the lower predictive value, relative risk and risk attributable to maternal nutritional deficit, for low birth weight. Also these curves showed a higher of obesity and a low predictive value for macrosomia. It is concluded that the curves used by the Ministry of Health must be revised.
