Ranging from the lower ambient temperature , the presence of snow cover , seasonal factors , and time of the day to location of fall , these factors have different levels of impact related to higher incidence or mortality of fall .
There existed systematic review on studies investigating the association between hip fractures and external risk factors including meteorological factors .
Albeit the fact that most serious common fall injury is a hip fracture , it can not account for all injuries forms of fall .
There was a lack of systematic review covering all fall-related injury or deaths to thoroughly summarise meteorological aspects of fall .
This study aim ed to systematic ally review epidemiological studies of fall and fall-related circumstances without restriction to hip fracture .
Effects of age on body temperature and blood pressure in cold environments.
Mean deep body temperature fell by 0.4 + /- 0.1 ( SD ) degrees C in five sedentary , clothed 63 - 70 year old men and by 0.1 + /- 0.1 degrees C in four young adults after 2 h exposure in still air at 6 degrees C ( P less than 0.001 ) . The mean increase in systolic and diastolic pressure was significantly greater ( P less than 0.002 ) in the older subjects ( 24 + /- 4 mmHg systolic , 13 + /- 4 mmHg diastolic ) than in the young ( 14 + /- 6 mmHg systolic , 7 + /- 3 mmHg diastolic ) after 2 h at 6 degrees C. A small rise in blood pressure occurred in the older men at 12 degrees C , but there was no increase in either group at 15 degrees C. The association of variables is particularly marked between systolic blood pressure and core temperature changes at 6 degrees C. There were no appreciable cold-adaptive changes in blood pressure or thermoregulatory responses after 7 - 10 days repeated exposure to 6 degrees C for 4 h each day . Blood pressure elevation in the cold was slower but more marked in the older men . These changes in blood pressure may provide a possible basis for delineating low domestic limiting temperature conditions
