Abstract:
Pilots' fatigue is one of the most serious threat to flying safety. Fatigue is influenced by many factors like sleep deprivation, daily activities, aging, stress, etc. This study was designed to investigate military pilots' daily activities. 20 pilots' daily activity was monitored by activity monitor, Fitbit(R), and the survey about sleep time and flight time was conducted. They placed Fitbit(R) on their waist for 5 days. During flight, they removed Fitbit(R) that had been used for checking their steps and walking distances. It was found that the average sleep time is 6.7 hours for fighter pilots. It was a little shorter than average sleep time for adults, 8 hours. Average steps per day was 6,838 which is more than sedentary worker's but less than active worker's. Their daily activities were not as high as we had expected. But their sleep time was very short. Flight surgeons should recommend them to take a rest and get sleep during rest period.Keywords:

C-reactive protein, a marker of chronic, low-grade inflammation, is strongly associated with current central adiposity, and has been linked to elevated risk of cardiovascular disease. Less is known about the contribution of longitudinal change in waist circumference to current inflammation. We evaluated the extent to which current waist circumference and change over an 11-year interval contribute independently to low-grade systemic inflammation measured in a group of 1,294 women, 35-69 years, participating in the Cebu Longitudinal Nutrition and Health Survey in the Philippines. Waist circumference was measured at the time of blood draw for CRP analysis in 2005 and during an earlier survey in 1994. A waist circumference delta variable was constructed by subtracting current circumference from past circumference. We used logistic regression models to predict having an elevated plasma CRP concentration (3 mg L(-1) < CRP < 10 mg L(-1)). Waist circumference in 2005 was a strong predictor of elevated CRP (OR 1.10, 95% CI = 1.08, 1.12, P < 0.001). In combined models, increase in circumference over 11 years was a significant and independent predictor of elevated CRP risk (OR = 1.023, 95% CI = 1.00, 1.05, P < 0.05). Considering the average increase over time, the cumulative risk of elevated CRP due to increased central adiposity was 25.7%. However, women who reduced their waist circumference between 1994 and 2005 had greatly reduced risk (6.2%), suggesting that even long-term inflammatory burden can be reversed by weight loss. Although current waist circumference is an important contributor to risk of elevated systemic inflammation in this as in other populations, history of central adiposity may be an independent phenomenon.

Community mobility post-stroke is important for gaining independence in daily activities. Walking devices can facilitate mobility, but it remains unclear whether individuals who use a walking device walk as many daily steps as those who do not require a device. It is also unclear whether these groups differ in their independence in daily living. This study aimed (1) to compare daily steps, walking tests, and independence in basic and instrumental activities of daily living (IADL) six months post-stroke between individuals who walk independently and individuals who use a walking device, (2) within each group to assess correlations between daily steps and walking tests, independence in basic and IADL.

We evaluated the accuracy of self-reported home-assessed and self-measured waist circumference in 101 men and eighty-three women aged 28-67 years. The main outcome measures were subjects' self-reported and self-measured waist circumference, and self-classification according to the previously defined waist action level 1 (940 mm in men, 800 mm in women) and action level 2 (1020 mm in men, 880 mm in women), and waist circumference measured by the investigator using the 'Waist Watcher' tape-measure, as the reference method. The mean errors (95% CI limits of agreement) for subjects' self-reported waist circumference (self-reported minus reference; mm) were -67 (95% CI -210, 77) in men and -43 (95% CI -211, 123) in women, and for self-measured waist circumference (mm) using the 'Waist Watcher' (self-measured minus reference) were -5 (95% CI -62, 52) in men and -4 (95% CI -50, 42) in women. The proportions of subjects classified into waist action level 1 or action level 2 by the investigator were used as the reference method. Self-reported waist circumference of men and women respectively would be classified correctly in different categories based on action level 1 with sensitivities of 58.3 and 78.7%, and specificities of 92.5 and 91.7%, and action level 2 with sensitivities of 35.3 and 44.9%, and specificities of 98.5 and 90.7%. Using the 'Waist Watcher' with different colour bands based on the action levels, male and female subjects respectively classified themselves into correct categories according to action level 1 with sensitivities of 100 and 95.7%, and specificities of 95.1 and 97.2%, and according to action level 2 with sensitivities of 97.1 and 100%, and specificities of 100% for both sexes. Only 2% of the sample misclassified themselves into the wrong categories according to waist circumference action levels. In conclusion, people tend to underestimate their waist circumference, but the 'Waist Watcher' tape-measure offers advantages over self-reported home-assessed measurement, and may be used as a screening tool for self-classifying the risk of ill health through intra-abdominal fat accumulation.

保健指導には，BMI（Body Mass Index，以下BMI）を初め，多くの健康指標が用いられているが，ウエスト値は，研究が少ないのが現状である．そこで，ウエスト値とBMIの関連，食生活・日常生活習慣との関連を明らかにするために調査を行った．A建設会社に勤務する35歳以上の男性社員213名を対象とし，定期健康診断時に，自記式質問紙と，ウエスト値測定，血液生化学検査による調査を行った．BMI，収縮期血圧，拡張期血圧，中性脂肪，GPT，γ-GTP，空腹時血糖値での異常値群は，正常値群と比較し，有意にウエスト値が太かった（p＜0.04）．ウエスト値と日常生活習慣の関連においては，揚げ物および外食を週4-5回以上摂取している群（p＝0.004），運動習慣が週に2-3回以下の群（p＝0.025）はウエスト値が有意に太かった．ロジスティック解析では，ウエスト値に関連が見られたものが疾病の有無（オッズ比2.10，p＝0.046），検査値異常の有無（オッズ比3.54，p＝0.009）であった．以上より，ウエスト値は健康指標の1つとして使用可能と考えられ，揚げ物や外食を控えたり，運動習慣を改善したりすることでウエスト値をコントロールし，内臓肥満予防に繋げることが出来るのではないかと考える．

Abstract This chapter considers the different types of rest for which provision is made under the Working Time Regulations 1998 (WTR): rest breaks, daily rest and weekly rest. The particular categories of workers who are excluded from the entitlements to rest are outlined. The difficult issue of rest for on-call workers is discussed, as is the scope of the duty on an employer to enforce the taking of rest by workers. The chapter concludes by looking at record-keeping, enforcement, and the remedies for breach of a worker’s entitlement to rest.
