the risk of tuberculous infection in sweden. | large sections of the population of sweden were tuberculin tested during the 1940s prior to bcg-vaccination. this material has been used to estimate the risk of tuberculous infection and its trends with calendar year and age. an analysis of the results of approximately 200,000 tuberculin tests in military recruits and schoolchildren was made, using the method developed in the tuberculosis surveillance research unit. the risk of infection was estimated to be 2-8 per cent at age 10 in 1935, the ra ... | 1975 | 1181701 |
meat, cooking methods and colorectal cancer: a case-referent study in stockholm. | the associations between methods of cooking meats and colorectal cancer were examined in a population-based case-referent study performed in stockholm in 1986-1988. the study included 559 cases and 505 referents. total meat intake, frequent consumption of brown gravy, and a preference for a heavily browned meat surface each independently increased the risk for colorectal cancer. the relative risks (rr) were higher for rectal than for colon cancer, and for boiled meat (rr colon = 1.7, rr rectum = ... | 1991 | 1917152 |
consumption pattern of infant foods by turkish immigrants. | fifty-nine turkish infants in metropolitan stockholm and two adjacent communities have been studied regarding food consumption pattern. the infants were breastfed for a shorter period than expected in turkey and shorter than in swedish children. illiterate mothers breastfed longer than those who had received some kind of education. formula feeding was extensively used. supplementary semisolid feeding was introduced, mainly at 4-6 months of age, much earlier than in turkey but rather later than i ... | 1986 | 3961305 |
biospheric 129i concentrations in the pre-nuclear and nuclear age. | in order to detect characteristic regional differences or temporal changes of 129i concentrations in the biosphere, thyroids from humans, grazing livestock, and herbivorous wildlife species (reindeer and roedeer) were collected in various areas of the world which are not affected by reprocessing plants. for reasons of comparison, all samples were analyzed for their 129i:127i atom ratios. human and bovine thyroids taken from the 10th region in southern chile (39 degrees-41 degrees south) indicate ... | 1993 | 8244695 |
