[The influence of hygiene and cultural characteristics of the family environment on dietary patterns of school children].

BACKGROUND: The diet of school aged children constitutes one of the basic pillars on which the health of an individual may be placed. The influence of the parents in dietary habits of children is absolute. The aim of the present study was to analyze what hygienic-cultural aspects of the familial environment are most linked to the diet of school children. METHODS: A study of non paired cases and controls was carried out in 48 children of 6-7 years of age (cases) with maximum consumption of cold meats and minimum consumption of vegetables and lettuce (universe = 131 children) versus a double control group of 34 children with inverse dietary patterns and 83 children who did not fulfill inclusion criteria of cases. Personal cleanliness and washing habits, attitudes towards television viewing, parental consumption of cigarettes and alcohol and sex education were also analyzed. RESULTS: Multivariant analysis identified a smoking father as a risk factor of worse diet (OR = 3.3, p = 0.016), with sex education received at home being associated with a decrease of 70% in the probability of having a bad diet (OR = 0.3, p = 0.016) on using the restricted control group. The smoker father was the only circumstance associated to bad diet on including the remaining children of the universe as controls (OR = 2.6, p = 0.018). CONCLUSIONS: The diet of school children seems to be related with the global attitude of the family with regard to health. Smoking habit of the father may represent a negative marker of food preferences with regard to quality of diet.

[Incidence of digestive system neoplasms. Trends. Soria 1981-1990].

The aim of this study was to evaluate, to compare and to identify the various incidence rate trends in digestive tract malignant tumours in the province of Soria. Tumor sites and histological types, patient's age, sex and town and area residence were studied. All new cases of digestive tract malignant tumours were collected during the 1981-1990 period. 30.4% of all malignant tumours in men (1906 patients) and 29% in women (1,256 patients) came from digestive tract sites. Incidence rates for each site were calculated for the two 1981-1985 and 1986-1990 subperiods. The histology, rates and trends of the tumours were compared with the other national and international cancer registries. Gastric cancer showed the highest adjusted rate for men (35.1 x 10(5) and colo-rectal cancer one for women (14.7 x 10(5). The lowest rates were for men in the gallbladder (0.5) and liver (1.1) sites; and for women in the gallbladder (1.6), whose diminishing trend was significant (2.92/0.75) (p < 0.05) and liver (0.5). Colorectal cancer showed a marked increase between the two subperiods for both sexes (men: 13.1/27.6) (women: 9.8/19.2). Pancreas cancer trends ascended for both sexes (men: 1.22/2.74) (women: 0.13/1.46). Gastric cancer rates in Soria are higher than the rest of the cancer registries in Spain while gallbladder, liver, and colorectal, cancer rates are one of the lowest for both sexes. Trends are significantly increasing in colorectal sites for both sexes (p < 0.01), and for women only in the pancreas (p < 0.05). The other cancer rate sites showed lesser variations and are not statistically significant.

[Dietary intake patterns in the school health program].

AIM: To investigate dietary intake patterns among school-students. DESIGN: An observational prospective study. A dietary survey was used to establish how many times habitual foods were eaten each week. SITE. The population of the northern half of the city of Soria. (North Soria Health Centre). PARTICIPANTS: All the school-children aged 6 and 7 (74 boys and 57 girls in both the private and public sectors) took part in the programme. MEASUREMENTS AND MAIN FINDINGS: The intake of foodstuffs was stratified as greatest in quartiles. The consumers of sweet "junk" foods also ate significantly more savory "junk" food (p = 0.00009). We found and inverse consumption relationship between savory "junk" foods and an intake of greens and root-crops (p = 0.03) and of pasta and rice (p = 0.008). The lower consumption of greens and fruits was linked to a lower consumption of fish (p = 0.023), to a lower consumption of meat (p = 0.037) and of meat products (p = 0.008). Lower consumption of eggs was linked to a greater consumption of meat (p = 0.016) and fish (p = 0.029). CONCLUSIONS: The consumption of savory "junk" foods and meat products can replace nutrients of a high biological value which are found in greens and root-crops. New studies to deepen the taxonomical analysis of the school diet are required. These should identify eating patterns which could endanger health in adult life.

[Mortality trends caused by neoplasms of the digestive system. Soria, 1950-1985].

The deaths caused by tumours of the digestive system (oesophagus, stomach, colon-rectum, gallbladder and pancreas) recorded in the province of Soria between 1950 and 1985 have been analyzed according to risk and mortality rates. Standardized (adjusted) rates in relation to sex and site of residence (urban-rural) of the deceased were calculated for the decades 1950-1959, 1960-1969, 1970-1979 and the period between 1980 and 1985. Standard errors were calculated to establish confidence limits according to Miettinen's method. The data were obtained from the death certificates of the various registries of the Soria province, including name and surnames, sex, age and site of the tumour according to the 9th revision of the International Classification of Diseases. There is a significant decrease in the mortality risk for tumours of the stomach in both sexes (p less than 0.01) and in liver tumours in females (p less than 0.01). On the other hand, there is an increased risk in both sexes for pancreatic cancer (p less than 0.05 M, p less than 0.01 F) and for oesophageal tumours in men (p less than 0.05). Similarly, during 1980-1985 men were at a significantly greater risk of dying from oesophageal, gastric and liver cancer (p less than 0.01) as well as rectum and colon (p less than 0.05). As far as stomach tumours are concerned there are significant differences between rural and urban areas both in males (p less than 0.01) and in females (p less than 0.05).

[Geographic study of cancer of the stomach in Spain in relation to agricultural activities].

The Spanish provinces with the highest risk of gastric cancer (CG) are in the Castilian meseta, where grain raising predominates. In other countries, high risk areas also correspond to inland, high altitude regions, and in some cases, like Chile, abundant fertilizer consumption. The present study attempts to relate the risk of this tumor in Spain to different types of agricultural activity. Pearson's linear correlation coefficient was calculated between the mortality rate due to gastric cancer in each of the 50 Spanish provinces and the different types of farming and cattle raising activities. The correlation with grain raising on nonirrigated land was positive and significant for mortality in both men (p less than 0.001) and women (p less than 0.01). The correlation between mortality from gastric cancer and cattle raising, particularly sheep, was also positive and significant in both sexes (p less than 0.001). The proportion of the irrigated and nonirrigated fields dedicated to fruit trees correlated negatively with mortality in both sexes, also with a significant difference (p less than 0.01). The authors suggest the need for further epidemiological investigation in Spain, particularly in areas of high risk of gastric cancer, to identify precisely the risk factors that could be related to agricultural activities.

[Correlation of the risk of gastric cancer in the province of Soria and the nitrate content of drinking water].

Diverse previous epidemiological studies have associated the risk of gastric cancer (CG) with the nitrate content of drinking water in certain high risk areas in Columbia and Denmark, but in other countries no relation has been found and the topic is still controversial. In the present study and analysis is made of the differential risk of gastric cancer in the province of Soria (Spain) in terms of mortality and incidence in each of the natural regions of this province, investigating an eventual correlation with the nitrate content of the drinking water. Although the maximum nitrate content found barely exceeded the maximum limits suggested by the WHO, these values have a statistically significant positive linear correlation with the adjusted mortality (p less than 0.01) and incidence rates of gastric cancer in men (p less than 0.05). The authors discuss the need for further investigation of the topic in Spain since the nitrate values encountered might not reflect the true magnitude of environmental nitrate exposure, or there could be other factors related to agricultural work in the grain-producing regions where the maximum rates of gastric cancer in men are recorded.

[Incidence and mortality of laryngeal neoplasms. Soria, 1950-1989].

Age-adjusted mortality and incidence rates for larynx cancer were calculated in Soria (urban and rural areas), for the 1950-89 and 1981-89 periods respectively. Both mortality and incidence rates were higher in urban area (p less than 0.01), and in males (p less than 0.01). There has been no increase in the mortality trend for the 1950-89 period. Age-adjusted incidence rates for men in Soria are higher respect to those reported in other countries. Soria and Murcia rates are the lowest in Spain larynx cancer records, being Asturias rates the highest in the world (20.6 per 100,000 population).
