Abstract

積雪地における高齢者の人力除雪の実態を明らかにし,体力,自立生活能力と除雪能力との関係を検討することが本研究の目的である.北海道各地の在宅高齢者に対しライフスタイルと身体活動に関するアンケート調査を実施し,男性334名,女性397名の有効回答を得た.さらに,調査対象者のうち男性102名,女性196名に対し文部科学省の体力テストおよび自立生活能力調査(ADL調査)を実施した.<BR>「降雪の毎に除雪をしている」と答えた割合は,男性の場合,65~69歳,70~79歳および80~89歳の各年齢層でそれぞれ80%,88%および73%,女性の場合,それぞれ46%,47%,27%と高い割合であった.男性の場合,通院中の群と通院していない群間および高血圧症の群と正常血圧の群間で「降雪の毎に除雪をしている」と答えた割合に差がなかったことから,多くの高齢者が無理を押してきつい作業に従事していることが示唆された.女性の場合,「降雪の毎に除雪をしている」群と「体力的に無理なのでしない」群との間で有意な差が見られた指標は,年齢(72.8±6.1と78.6±7.3歳),身長(148.2±5.4と145.3±7.0cm),握力(22.7±5.0と19.1±5.3kg),10m障害物歩行(10.1±3.9と13.2±5.3秒),6分間歩行(494±77と426±88m)およびADL得点(27.1±4.5と22.0±4.7点)であった.これらの結果から,積雪地の高齢者にとって筋力、脚パワーおよび持久性などの体力が除雪の重要な決定要因であることと結論される

The purposes of the study are to make clear the present situation of snow removal maneuver performed by older adults in snowy regions and to elucidate the interrelationship among physical fitness, activities of daily living and capability of snow removal.<BR>Questionnaires on lifestyle and physical activities were distributed to 334 elderly males and 397 elderly females who are living independently in Hokkaido. Among these respondents, physical fitness test developed by Japanese Ministry of Education, Science and Culture and questionnaires on Activities of Daily Living were performed on 102 elderly male subjects and 196 female subjects to extract the physical fitness factors for snow shoveling.<BR>Higher percentages of the respondents answered to be engaging snow removal every snowfall, that is to say, 80%, 88% and 73% at age ranges of 65-69, 70-79 and 80-89 years in males, and 46%, 47% and 27% at age ranges of 65-69, 70-79 and 80-89 years in females, respectively. Since no difference was seen in the percentages of the subjects who are engaging snow removal every snowfall between the groups either outpatients group and non-outpatient group, or high blood pressure group and normotensive group in males, a large part of older adults males strain themselves demanding work. Significant differences were observed in mean values in age, physical fitness between the two female groups who are engaging snow removal every snowfall and the female group who are impossible to snow removal because of lower fitness, that is to say, 72.8±6.1 vs 78.6±7.3years in age, 148.2±5.4 vs 145.3±7.0cm in height, 22.7±5.0 vs 19.1±5.3kg in grip strength, 10.1±3.9 vs 13.2±5.3 sec in 10m hurdle walk time, 494±77 vs 426±88 m in 6-minutes walk distance, and 2'7.1±4.5 vs 22.0±4.7 point in activities of daily living score, respectively.<BR>Therefore, it was concluded that physical fitness factors such as strength, leg power, endurance are an important determinants of the snow removal for older adults in snowy regions.
