[Athletic injuries in wind surfing].

We made an anamnesis of sports related injuries for 189 members of the Swiss Wind Surfing Federation. This data enabled us to calculate an yearly incidence of 0.02 injuries per athlete. By comparison, this frequency amounts to 0.03 for tennis players, to 0.24 in football and 2.30 for competitive cyclists. Feet injuries made up for 36.5% of all cases, whereas legs were affected for 23.5%. The athlete had to stop his training for 25.2 days on average. His work had to be interrupted for 10.2 days and his mean hospital stay was of 2.0 days. One third of all injuries were due to board contact events, 20% happened on the shore and 19% were ascribed to falls on/of the mast. Bruises and other wounds were mainly due to the lack of surf-shoes and/or other protective clothing items.

[Accidents in delta sailing].

We interviewed a group of 259 deltasailors about their injuries which befell them in Switzerland during their sports activity. They reported on 257 incidents, 8% of which were contusions and 24% resulted in fractures. 70% of all injuries affected the arms or legs, whereas 30% were located on the head or trunk. An accident occurred far more often during the landing phase (72%) than at take-off (28%). The mean hospital stay was noticeably longer for injured women (15 days) than for men (8 days).

Intra and inter-person sources of variability in fat intake in a feeding trial of 14 men.

An impediment to analyzing the effect of nutritional factors on biologic processes or health status in human populations arises from the relatively small dietary differences that exist between individuals in relation to large periodic fluctuations in dietary intake and the imprecision with which diet is normally assessed. We report here on characteristics of dietary variability in a group of 14 young men who successfully completed an intervention study specifically designed to create large differences in fat intake between baseline and two dietary intervention-periods each lasting two months (during which safflower and coconut oil supplements were given). We found that in the second supplemental phase of the intervention inter-person sources of variability were greatly increased over the low-fat baseline values. For proportion of calories as fat it increased to 64.2% of total variance from 21.6% without supplementation; for saturated fatty acids, 47.3% from 17.7%; for polyunsaturated fatty acids, 62.4% from 22.8%; and for the P:S ratio, 71.5% from 21.6%. During the first intervention phase we observed only moderate changes. Reasons for the intervention phase differences in effect, implications for feeding trials designed to look at dietary fat effects, and the need for future studies aimed at clarifying these results are discussed.

[Sport-specific injuries in weight lifting].

121 weight-lifters reported their past injuries due to their sport. 32% never had had any sports related medical problem. From the remaining 68%, 202 instances of injuries related to weight lifting were reported. They affected the knees (25%), scapular girdle (22%), back (21%), wrist (12%) and the elbows (6%). In about 10% of the known cases of knee injury, the rest period without any sports activity lasted more than 28 days. More often than not, it was due to degenerative processes of the joint. Sportsmen fear particularly shoulder injuries during the snatch movements. Accidents could be prevented to a large extent by relevant preventive actions such as warm-up exercises, a strict hygiene of the weights and devices and, most importantly, stable footwear.

[Tobacco, alcohol and drug consumption of the working population in Switzerland].

In a study in Switzerland we checked the consumption of tobacco, alcohol and medicaments of 1033 women and 1260 men engaged in 44 factories in Switzerland. Cigarettes smoked 54% of the women, but only 44% of the men in the age from 20-35. No alcohol drank 10% of the feminine and 4% of the masculine employees. At the time of the study 27% of all women and 16% of all men took medicaments of any kind, but only one third of all were prescribed by a doctor.

[Stress load of management personnel. Results of a survey].

Out of 258 managers with top or middle management jobs in industry and economics, 8% felt themselves as being very strongly under stress and a further 23% as being strongly under stress. Moreover, every tenth manager felt that he was powerless against his stress problems. In 38% the stress was compensated for by sporting activities, however, in 9% medication compensated for the stress, whereby only in half of the cases had the tablets been prescribed by a doctor. It is remarkable, that 10% of the managers interviewed had not had a holiday in the previous year and similarly 10% stated that they had no time for sport in their spare time. These persons had to be specially treated with "preventive" medical measures, especially since overweight, high blood pressure and a high tobacco consumption have to be taken into consideration in such cases, as shown by our comparative studies.

[Preventive medicine in old religions].

This paper describes religious laws about hygienic problems in the old cultures. Special problems have been the prevention of infectious diseases, but also the problems of nutrition. The old laws had no great preventive efficiency, because the causes of the most diseases were unknown.
