To examine differences in objective and subjective outcomes in outpatients undergoing percutaneous coronary intervention (PCI) performed for acute myocardial infarction versus cardiac surgery (CS) following a phase II cardiac rehabilitation (CR). Longitudinal observational study of 437 consecutive cardiac outpatients after 8 weeks of phase II CR. Patients were divided into the PCI group (n = 281) and CS group (n = 156). Handgrip and knee extensor muscle strength, peak oxygen uptake (VO2), upper- and lower-body self-efficacy for physical activity (SEPA), and physical component summary (PCS) and mental component summary (MCS) scores as assessed by Short Form-36 were measured at 1 and 3 months after PCI or CS. All outcomes increased significantly between months 1 and 3 in both groups. However, increases were greater in the CS versus PCI group in handgrip strength (+12.3 % vs. +8.1%, P < 0.01), knee extensor muscle strength (+19.3% vs. +17.5%, P = 0.008), peak VO2 (+20.9% vs. +16.9%, P < 0.01), upper-body SEPA (+27.7% vs. +9.2%, P = 0.001), and PCS score (+6.5% vs. +4.1%, P = 0.001). Although this relatively short-term phase II CR increased all outcomes for both groups, outcomes showed the recovery process was different between the PCI and CS groups, slightly favoring CS patients. Furthermore, patents in the field of CR are presented. © 2011 Bentham Science Publishers.

OBJECTIVES:According to the interim report "National Health Promotion in the 21st Century (Healthy Japan 21)", the Exercise and Physical Activity Guide for Health Promotion 2006 (EPAGH2006) is an im-portant resource in the field of physical activity in Japan. A previous study (Higo & Nakamura, 2008) showed that although the awareness level of EPAGH2006 was lower than for other health pro-motion policies (e.g., Healthy Japan 21), the proportion of people who walked regularly was higher in the EPAGH2006 awareness group than in the no-awareness group. This result indicates that pro-motion of EPAGH2006 would contribute to increase in the number of physically active people. The purpose of the present study was to identify longitudinal change in awareness of EPAGH2006, and to examine the relationship with levels of physical activity.;METHODS:The subjects were 1,100 Japanese adults (mean [SD], 39.8 [10.1 years) recruited from among the registrants of a Japanese social research company. This longitudinal study was conducted using online questionnaires in surveys in November 2007 (T1) and December 2008 (T2). The awareness level of EPAGH2006 was assessed with 3 choices, i.e., good understanding, awareness and no-awareness. The International Physical Activity Questionnaire short Version (Craig et al., 2003; Murase et al., 2002) was used to estimate the amount of physical activity that the subjects engaged in. The Mann-Whitney test was utilized to assess inter-group differences in changes in the amount of physical activity between the understanding and no-awareness groups.;RESULTS:The proportion of those who fully understood EPAGH2006 was 1.4% at T1 and 2.2%0 at T2 and did not significantly increase. The physical activity level in the understanding group at T2 was significantly decreased compared with the no-awareness groups at both T1 and T2 (p=0.013).;CONCLUSION:The lack of increase in the awareness level between the two time points suggests that dissemination of EPAGH2006 has not been effective. A more strategic approach would appear to be required. However, the results also did not indicate that the awareness level of EPAGH2006 had a positive in-fluence on physical activity. Further studies, conducted when the awareness levels improve, may elucidate the relationship between the levels of EPAGH2006 awareness and physical activity.

Background–Several non-pharmaceutical policies, which include stay-at-home orders, mobility restrictions, and quarantine, have been implemented to reduce the spread of novel coron-avirus disease 2019 (COVID-19). The present study examines work style changes among company workers after COVID-19 and analyses their effects on workers’ domain-specific sedentary and active behaviours. Methods-We analysed data from a nationwide prospective online survey in Japan. The data were obtained in February 2019 (n = 3200) and in July 2020 (n = 1709) from the registered individuals of a Japanese internet research service company. The participants reported work style patterns before and after the outbreak of COVID-19 in the follow-up survey. Domain-specific sedentary behaviours and physical activities were assessed by questionnaires. Paired t-tests were used to compare work styles before and after the outbreak of COVID-19. Multivariable linear regression models were used to assess the associations between changes in work style and changes in sedentary behaviours and physical activities. Results. Workers had more working from home days and fewer office-based working days after the outbreak of COVID-19 (p < 0.001 and p < 0.001, respectively). The increase in the number of working from home days per week was significantly associated with increases in work-related sitting time and total sitting time (b = 0.16, 95% CI 0.08, 0.24, p < 0.001 and b = 0.23, 95% CI 0.11, 0.36, p < 0.001, respectively). However, it was also associated with a decrease in car sitting time (b = −0.04, 95% CI −0.06,-0.01, p < 0.001). In addition, the increase in the number of working from home days was associated with a decrease in work-related moderate physical activity (b =−0.06, 95% CI −0.10, −0.02, p < 0.001). Conclusions. Our study provided preliminary evidence of an increase in working from home days in response to COVID-19 in Japan and of how this increase in the number of working from home days has affected workers’ sedentary behaviours and physical activities. These findings shed light on the effects of COVID-19 on work styles and workers’ sedentary behaviours and physical activity.

Background: Dog ownership is emerging as an important correlate of sufficient physical activity and therefore has the potential to positively affect a portion of the population. A growing body of literature indicates that dog-walking contributes to increased physical activity. However, most of the previous studies have been conducted in Australia or the U.S. and have sampled from the general adult population. Purpose: This study examined the association between dog ownership, dog-walking, and physical activity in older Japanese adults. Methods: Participants were community-dwelling residents aged 65-74 years who responded to a population-based cross-sectional survey (N=1926). Physical activity, dog ownership, dog-walking, and sociodemographic attributes were self-reported (collected in 2010 analyzed in 2011). ANCOVAs and multivariate logistic regressions were used. Results: Overall, 14.0% of older adults were dog owners, with 71% reporting that they walked their dog for an average of 308.5±300.7 minutes/week. Dog walkers reported more minutes/week of moderate-to-vigorous physical activity (M±SE: 241.7±27.0) and total physical activity (M±SE: 698.6±40.6) than both non-dog walkers (M±SE: 110.7±41.8 M±SE: 527.2±62.9) and non-dog owners (M±SE: 164.7±9.1 M±SE: 519.2±13.7), respectively (p<0.05). Dog walkers also walked more minutes per week (M±SE: 508.0±33.4) than non-dog owners (M±SE: 384.5±11.3 p<0.05). Dog walkers were more likely to be sufficiently active than both non-dog walkers and non-dog owners (p<0.001). Conclusions: Use of dog-walking may be a potentially viable means of intervention for increasing walking and overall physical activity in older Japanese adults. © 2012 American Journal of Preventive Medicine.

Background: In addition to insufficient moderate-to-vigorous physical activity (MVPA), prolonged sitting time is also a health risk for older adults. An understanding of population subgroups who have prolonged television viewing (TV) time, a predominant sedentary behavior, can aid in the development of relevant health promotion initiatives; however, few such studies have focused on older adults, the most sedentary segment of the population as a whole. The aim of this study is to examine the socio-demographic attributes associated with TV time among community-dwelling Japanese older men and women.Methods: A population-based, cross-sectional mail survey was used to collect data on TV time, MVPA, and socio-demographic characteristics. The survey was conducted from February through March 2010. Participants were 2700 community-dwelling older adults (aged 65-74 years, 50% men) who were randomly selected from the registry of residential addresses of three cities in Japan. Data from 1665 participants (mean age: 69.5 years, 52% men) who completed all variables for the present study were analyzed. Multivariate logistic regression analyses were used to calculate the odds ratios (ORs) of prolonged TV time (2 hours/day) for each socio-demographic attribute, stratified by gender.Results: Of the 1665 participants, 810 (48.6%) watched TV for more than 2 hours/day. The median television viewing time (25th, 75th percentile) was 2.00 (1.07, 3.50) hours/day. Prolonged TV time was associated with not in full-time employment, lower educational attainment, weight status, living in regional areas and low MVPA for the whole sample. For men, prolonged TV time was associated with lower educational attainment; (OR = 1.53, 95% CI: 1.12 2.07), underweight (OR = 1.63, 95% CI: 1.02-2.60), overweight (OR = 1.57, 95% CI: 1.11-2.21), and low MVPA (OR = 1.43, 95% CI: 1.02-2.02). For women, living in regional areas (OR = 2.02, 95% CI: 1.33-3.08), living alone (OR = 1.61, 95% CI: 1.03-2.49), not driving (OR = 1.79, 95% CI 1.21-2.65), overweight (OR = 1.50, 95% CI: 1.00-2.24), and low MVPA (OR = 1.51. 95% CI: 1.05-2.17) were associated with prolonged TV time.Conclusions: These findings identify particular socio-demographic and behavioral characteristics related to TV time among Japanese older adults. It should be noted that correlates of prolonged TV time differed by gender. Women in living situations with limited transportation options tended to spend prolonged time watching TV. Health promotion initiatives for older adults, particularly for older women, may be more effective if they take these attributes into account.

Background: It is vital to reduce the proportion of sedentary behavior in children. Understanding the duration and behavioral context is needed. The present study examined school-grade and sex differences in domain-specific sedentary times and concurrence with screen-time guidelines among Japanese elementary school children.Methods: A total of 625 children (330 boys) were surveyed in 2010 and 2014. Using a questionnaire, data regarding participants' grade (first through third grades: lower grades; fourth through six grades: higher grades), sex, weight, and height were collected in addition to the time spent per day engaging in each specific sedentary behavior separately: (1) reading or listening to music, (2) TV or video viewing, (3) TV game use, (4) internet use excluding class, (5) homework, and (6) car travel. Two-way analysis of covariance and logistic regression analyses, adjusted for BMI and moderate to vigorous physical activity, were used to examine school-grade and sex differences in sedentary behaviors and the independent risk of exceeding recommended total daily screen time ( 2 h).Results: On 625 children, mean minutes (SD) of sedentary behavior per week in (1) - (6) were 90.3 (123.4), 535.0 (356.6), 167.3 (222.1), 23.9 (70.9), 264.9 (185.3), and 33.4 (61.2) in weekdays and 42.1 (70.0), 323.9 (232.0), 123.0 (96.4), 15.8 (49.9), 74.4 (96.4), and 71.3 (84.9) in weekends, respectively. There were differences in the minutes of sedentary behavior between participants of 2010 and 2014; e.g., TV game use and homework in weekdays and weekdays and car travel in weekends. Boys spent more time in TV game use, and girls spent more time reading, listening to music, doing homework, and car travel. Higher-grade students spent more time reading or listening to music, using a computer, and doing homework. Higher-grade students were 2.09 times (95% CI: 1.32 - 3.30) in whole week, 2.08 times (95% CI: 1.45 - 3.00) in weekday, and 1.88 times (95% CI: 1.29 - 2.74) in weekend more likely to spend = 2 h per day in domains (2) - (4) (screen-time) than lower-grade students.Conclusions: Time spent engaging in each domain-specific sedentary behavior differed according to sex and school grade. Higher-grade students were less likely to meet screen-time guidelines. These findings highlight the need for domain-focused strategies to decrease sedentary behavior in Japanese school-age children.

The purpose of this study was to explore patterns of lifestyle walking behavior among Japanese adults aged 30-49 and to identify their sociodemographic characteristics.A sample of 5,009 was collected from registrants of a social research company. The study was a cross-sectional survey using the Internet. Measured variables were walking behavior in five domains (commuting, working, shopping, exercising and other movement) and sociodemographic characteristics. Hierarchical cluster analysis was utilized to identify walking patterns.Four walking behavior clusters were identified: cluster 1 (N=1,089) walking while commuting, working and shopping; cluster 2 (N=381) walking while commuting; cluster 3 (N=1,257) walking for exercise; cluster 4 (N=1,161) walking while shopping. Cluster 1 had the highest proportion of walkers who met physical activity recommendations. Also it had a high proportion of women who were unmarried, employed, without children, or finished university or graduate school. Cluster 2 showed a high proportion of men who were married, with children, with high household income, or finished university or graduate school, and women who were married, employed, without children, with high household income, or finished university or graduate school. Cluster 3 had a high proportion of women aged 40-49. Cluster 4 showed a low proportion of men with high household income and a high proportion of women who were married, unemployed, or with children.This study indicated that walking behavior patterns in both genders was different depending on marital status, number of children, educational level and household income. In addition, the employment status of women had apparent effects on these patterns.

Purpose: Environmental initiatives to support walking are keys to noncommunicable disease prevention, but the relevant evidence comes mainly from cross-sectional studies. We examined neighborhood environmental attributes associated cross-sectionally with walking and those associated prospectively with walking maintenance. Methods: Data were from the Australian Diabetes, Obesity and Lifestyle study collected in 2004-2005 (baseline) and in 2011-2012 (follow-up). Participants who did not move residence during the study period (n = 2684, age range: 30-77 yr at baseline) were categorized as regular walkers (walked five times per week or more) or not at baseline. Regular walkers were divided into those who stopped and those who maintained regular walking at follow-up. Regression analyses examined relationships of regular walking and walking maintenance with perceived attributes of neighborhood destinations and pedestrian environments. Results: Regular walking at baseline was significantly associated with availability of shops (odds ratio [OR] = 1.13, 95% confidence interval [CI] = 1.04-1.22), many alternative routes (OR = 1.12, 95% CI = 1.01-1.23), park or nature reserve (OR = 1.13, 95% CI = 1.02-1.26), bicycle or walking tracks (OR = 1.08, 95% CI = 1.00-1.17), and feeling safe to walk (OR = 1.18, 95% CI = 1.01-1.38). Maintenance of regular walking was associated with the availability of multiple alternative routes (OR = 1.19, 95% CI = 1.03-1.38). Having many alternative routes and walking tracks was associated with walking maintenance among those who were not or had stopped working. Conclusions: Neighborhood destinations (shops and parks) and pedestrian environments (alternative routes, walking trails, and safety from crime) were found to be associated with regular walking, but only pedestrian environment attributes were found to be related to the maintenance of regular walking. Further evidence from prospective studies is required to identify other neighborhood environmental attributes that might support walking maintenance.

OBJECTIVE: Leisure-time sedentary behaviors (LTSBs) have been associated adversely with health outcomes. However, limited research has focused on different categories of LTSB. We aimed at identifying categories of LTSBs and examining their separate associations with indices of health among Japanese older adults. METHODS: A postal survey collected data on self-reported health, psychological distress, body mass index, moderate-to-vigorous physical activity (MVPA), LTSBs (five behaviors) and socio-demographic characteristics from 1,580 Japanese older adults (67% response rate; 65-74 years) in 2010. Exploratory factor analysis was used to classify LTSBs. Odds ratios (ORs) were calculated for associations of LTSB categories with self-reported health, psychological distress, overweight, and lower MVPA. Data were analyzed in 2013. RESULTS: Two categories of LTSB: passive sedentary time (consisting of TV time, listening or talking while sitting, and sitting around) and mentally-active sedentary time (consisting of computer-use and reading books or newspapers) were identified. Higher passive sedentary time was associated with a higher odds of being overweight (OR: 1.39, [95% CI: 1.08-1.80]), and lower MVPA (1.26, [1.02-1.54]). Higher mentally-active sedentary time was associated with lower odds of lower MVPA (0.70, [0.57-0.86]). CONCLUSIONS: Two types of sedentary time-passive and mentally-active-may play different roles in older adults' well-being.

目的健康日本21の中間報告書では、身体活動•運動分野の重点課題の 1 つとして「エクササイズガイド2006の普及」が挙げられている。一方、肥後•中村（2008）によれば、エクササイズガイド2006の認知者の割合は、他の健康づくり施策よりも低いものの、エクササイズガイド2006認知者の方が歩行習慣者の割合が多いことが報告されている。本研究の目的は、エクササイズガイド2006の認知度の経時変化を検討することと、エクササイズガイド2006の認知と身体活動量との関連性を縦断的に検討することであった。
方法対象は、社会調査モニター1100人（39.8±SD10.1歳）であった。2007年11月（T1）、2008年12月（T2）の計 2 回、インターネットを用いた質問調査を縦断的に実施した。エクササイズガイド2006の認知度は、「内容を知っている」、「聞いたことはあるが内容は知らない」、「聞いたことがない•今回の調査で始めて知った」の 3 段階で評価した。週当たりの身体活動量（METs•時/週）は、IPAQ–SV（Craig et al., 2003；村瀬他、2002）を用いて推定した。Mann–Whitnney 検定を用いて、期間中にエクササイズガイド2006を認知した者と、認知しなかった者の身体活動量の変化量を比較した。
結果エクササイズガイド2006の内容を知っていた者の割合は、T1 で1.4%、T2 で2.2%であり、認知度の有意な経時変化は認められなかった。調査期間中にエクササイズガイド2006を知った者の方が、両時点とも知らなかった者と比較して、身体活動量が低下傾向にあった（P=0.013）。
結論1 年間で認知度は向上しておらず、我が国においてエクササイズガイド2006の普及は進んでいないことが示唆された。エクササイズガイド2006の戦略的な普及方策の検討が求められる。ただし、先行研究とは異なり、エクササイズガイド2006を認知することが、身体活動の促進に対して肯定的な影響を与える可能性は示されなかった。普及が進み、認知度が向上した段階で検討を行うことで、両者の関係がより明確となるだろう。

【はじめに、目的】 健康関連QOL(HRQOL)を向上させる因子の一つとして、身体活動セルフ・エフィカシー(SE)が注目されている。SEとはBanduraによると「ある結果を生み出すために必要な行動をどの程度うまく行うことができるかという個人の確信」と定義されている。特に運動や身体活動に関するSEは、身体活動や行動変容や運動の継続、更にはHRQOLに関係するとされている。しかしながら人工膝関節全置換術(TKA)患者に対して、身体活動SEが身体機能およびHRQOLに及ぼす影響について明らかにされていない。本研究の目的はTKA後のリハ介入における身体機能、HRQOLおよび身体活動SEの回復過程とその関連性について明らかにすることである。【方法】 対象は2010年10月から2011年7月までに当院でTKAを施行した変形性膝関節症患者44例48膝とした。手術時年齢は73.2±7.7歳、BMI26.1±3.5 kg/m2，術後在院日数25.2±5.3日、術後リハは当院プロトコールに準じて術後3ヶ月間外来リハを実施した。身体機能評価としてTimed Up and Go test(TUG)、開眼片脚起立時間、膝伸展筋力を測定した。HRQOLの評価指標としてSF-36の下位8尺度である身体機能(PF)、日常役割機能－身体(RP)、体の痛み(BP)、全体的健康感(GH)、活力(VT)、社会生活機能(SF)、日常役割機能－精神(RE)、心の健康(MH)と身体的サマリースコア(PCS)と精神的サマリースコア(MCS)を用いた。身体活動SEは虚弱高齢者の身体活動SE尺度（歩行、階段、重量物）とその総合得点を用いた。評価は術前、術後1ヶ月(退院時)と3ヶ月(外来通院時)とした。統計解析は回復過程を一元配置分散分析とBonferroni多重比較、身体機能およびHRQOLと身体活動SEとの関連性に関しては各変化量をpearsonの相関係数を用い、有意水準は5%未満とした。【倫理的配慮、説明と同意】 本研究は当院生命倫理委員会の承認(0826)を受け、対象者に研究内容の説明文書を用いて口頭による説明を行い、研究参加への同意を得て実施した。【結果】 各項目は術前(T1)→術後1ヶ月(T2)→術後3ヶ月(T3)の順に平均値±標準偏差で示した。TUGは11.8±3.8→11.7±3.8→10.5±3.3秒となりT1とT3，T2とT3で有意に改善した。開眼片脚起立時間は13.3±19.3→20.8±26.1→23.2±31.8秒となりT1とT3で有意に向上した。膝伸展筋力は0.5±0.2→0.5±0.1→0.6±0.1N・m／kgとなりT2とT3で有意に向上を認めた。SF-36の下位尺度のうち、PFは37.7±20.8→40.6±25.6→52.5±20.3点、BPは35.1±15.3→36.2±19.2→49.8±21.2点、SFは53.9±27.1→56.8±25.3→69.8±23.5点となりT1とT3，T2とT3で有意に改善を認めた。GHは48.8±13.6→53.5±14.5→54.1±16.5点となりT1とT3で有意に改善を示した。PCSは16.5±12.5→15.3±14.6→23.1±16.1点となりT1とT3，T2とT3で有意に改善した。身体活動SEのうち、歩行SEは12.4±5.0→14.9±6.4→15.9±5.3点、階段SEは8.9±5.2→10.4±5.2→12.5±5.1点、重量物SEは14.1±5.9→15.7±5.3→17.3±6.1点となりT1とT3で有意に向上した。身体活動SEの総合得点では35.4±12.5→41.1±13.1→45.6±12.8点となりT1とT2，T1とT3で有意に向上を認めた。身体活動SEの総合得点とHRQOLとの関連性はPF、RP、BP、RP、GH、REおよびPCSと有意な正の相関を示した(r＝0.307～0.508，p＜0.05)。身体活動SEの総合得点と身体機能の各項目とは有意な相関が見られなかった。【考察】 身体機能、HRQOLおよび身体活動SEは時間経過とともに有意に改善を示した。退院時では十分な改善が得られず、退院後もリハの継続が必要になると考える。身体機能と身体活動SEはHRQOLと関連性があり、身体機能とは関連性がないことが示唆された。HRQOLを向上させるためには、身体機能に加え、身体活動SEを高めるような方策を積極的にリハに組み入れていく必要があると考える。【理学療法学研究としての意義】 TKA後のリハは身体活動SEを高めるアプローチを加えることで、TKA患者のHRQOLを向上させることが可能になると考える。

In addition to intensity and quality, diversity of activity will be an important factor to explain health outcomes among older adults. Few studies, though, examined an association between activity diversity and health outcomes. This study aimed to examine the association between activity diversity and frailty among community-dwelling older Japanese. Participants were community-dwelling older adults who participated in a cohort study, the “Otassya-Kenshin” in 2018 . The participants were asked frequency of 20 daily activities, inside/outside chores, leisure activities with/without physically, direct/indirect contact with friends and so on, in a week and activity diversity score were calculated using the formula of Shannon’s entropy. Frailty was defined by the Japanese version of the Cardiovascular Health Study criteria. The difference in diversity score between frail and non frail were examined by t-test. Logistic regression analysis with covariates, age, sex, economic status, living alone, BMI, Mini-Mental State Examination, and IADL was adopted to find association between activity diversity score and presence of frailty. Of 652 participants (age: 72.8±6.3, women: 60.6%) analyzed, 27 (4.1%) were defined as frail. Frailty group revealed significantly lower activity diversity score than non-frailty group (0.66±0.11 vs 0.75±0.08, Plt;0.01). 0.2 point of decrease in diversity score increase 5 times chance of frailty after controlling covariates. We found significant relationship between activity diversity and health outcome among older subjects. The activity diversity may provide additional information to number or intensity of activity.

Background

Although the main targets for reducing workplace sedentary behavior have been clarified, only a few studies have examined the association between social-ecological factors and workplace sedentary behavior for effective intervention. The present study aimed to examine the social-ecological factors of workplace sedentary behavior among Japanese sedentary workers.
Methods

Participants were recruited via a cross-sectional mail survey targeting randomly sampled 6000 middle-aged people dwelling in Matsuyama-city and Koto-ku in Japan. Participants answered a questionnaire on social-ecological factors, recorded their work time in a diary, and wore a triaxial accelerometer during waking time for 7 consecutive days. Workplace sedentary behavior was measured using accelerometer and was referred to as the work time in the recorded diary. Full-time workers who had mainly sitting work and valid accelerometer data were included in the analysis. Workplace sedentary variables were sedentary breaks per sedentary hour, sedentary time, and ≥ 30 min bouts of sedentary time. The associations between each sedentary variable and social-ecological factors were explored by conducting three multiple linear regression analyses adjusting for sociodemographic and health-related factors.
Results

A total of 227 participants (133 men, mean age 49.9 ± 6.9 years) were included in the analysis. In the overall sample, “typically seeing work colleagues take sedentary breaks” was significantly associated with more sedentary breaks (B [95% confidence interval {CI}=1.40 [0.07 to 2.73]) and shorter ≥30-min bouts of sedentary time (B [95% CI] = −7.08 [−13.75 to −0.40]). “I am motivated to take sedentary breaks” had an unfavorable association with less sedentary breaks (B [95% CI] = −1.36 [−2.61 to −0.12]) and longer sedentary time (B [95% CI] = 4.15 [0.29 to 8.00]). In male workers, “Too stressed to take sedentary breaks” was significantly associated with less sedentary breaks (B [95% CI] = −5.6 [−9.17 to −2.02]).
Conclusions

Seeing work colleagues take sedentary breaks may be important for reducing workplace sedentary behavior. Those who are more sedentary are motivated to take sedentary breaks. Male workers who feel the need to take sedentary breaks at work are more sedentary.
