[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.

[Stress among businessmen (author's transl)].

An enquiry was conducted into the stress problems of 118 independent businessmen in Switzerland aged between 24 and 67 years. 19% were receiving medical treatment compared with 21% of 1260 representatively registered employed men from 44 random samples from factories in North Switzerland. About one third of the treatment diagnoses were due to stress conditions. 45% of those registered were smokers, 14% of them pipe smokers. 57% were overweight. 91% took exercise, 19% of them for up to 10 hours weekly. 2% described the general feeling of stress as very strong, 29% as strong, 36% as medium and 31% as weak and 11% none at all. Only 4% admitted very severe or severe family stress, 16% medium, 23% slight and 57% none, but 21% complained of very great or great business stress, 34% medium, 33% slight and only 11% none.

[Normogram study of the health of male industrial workers in northern Switzerland. Part 3: present medical care - frequency].

A study has been conducted to obtain representative data on the health of industrial workers in northern Switzerland. 1260 men from 44 plants were covered. At the time of the study 21.3% were under treatment by a doctor. From all these patients 14.4% were suffering from heart diseases, 12.6% from articular rheumatism and muscle diseases, 10.3% from neurological and 9% from dermatological diseases. Of subjects aged 43--65, 1.7 times more were under treatment by a doctor than subjects aged 20--42.

[Stress in journalists (author's transl)].

The stress problems of 227 Swiss journalists with a mean age of 43 years (189 men) and 39 years (38 women) were recorded by means of questionnaires (76% returns). About 90% of all those questioned admitted suffering from stress at the present time. However 88% of the juniors and 96% of the seniors enjoy their work. 20% of all those questioned were anxious about their livelihood. 97% of the total live under pressure of deadlines, only one in 3 has regular working hours. Half the younger and two fifths of the older men admitted some form of family stress, usually in connection with their occupation. 76% of the younger and 70% of the older journalists questioned have a hobby. 70% of the juniors occasionally take exercise, as do 48% of the seniors. About 50% of both the men and women are smokers. The general state of health is stated to be good by 80% of younger and 70% of older subjects. A comparison of the results according to occupational stress, work stress, deadline stress, stress of livelihood, stress of recognition, family stress and stress to health shows that only a very differentiated manner of consideration is permissible.

[The weather and skiing accidents (author's transl)].

During the winter of 1974/75, 528 skiing accidents in the Davos area were investigated in connection the weather influences. It was found that during high pressure conditions the accident rate increased and was very low under low pressure conditions. This result is explained by high pressure conditions often inducing the skier to more daring modes of skiing. Consequently the fine weather influences the accident risk to skiers through mental stimulation. The low accident rate in low pressure conditions can be explained insofar as in bad weather only advanced skier dare to go on the ski-run and the danger-prone beginners stay at home. In addition most skiers are conscious of the risk in unpleasant weather and ski correspondingly carefully. The accident rate decreased from the beginning to the end of the 1974/75 season.
