Impacts of ambient temperature and seasonal changes on sports injuries in Madrid, Spain: a time-series regression analysis
Objectives: Recreational physical activity is an integral part of our society, and the injuries caused by sports activities are a concern for public health. We studied the effect of outdoor ambient temperature on hospital emergency department visits caused by sports injuries in Madrid, Spain, and accounted for its seasonal changes.Methods: We used a time-series design. Data was analysed with quasi-Poisson regression models. We calculated the proportion of emergency visits attributable to seasonal changes before and after adjusting for daily ambient temperature. We modelled the association between emergency visits and temperature using distributed lag non-linear models.Results: The proportion of emergency visits attributable to seasonal changes was 24.1% and decreased to 7.6% after adjusting for temperature. We found a high risk of emergency visits associated with cold and hot temperatures, whereas the risk was higher for heat.Conclusion: Sports and recreational physical activity injuries are not rare events; therefore, appropriate healthcare decisions should consider the impact of outdoor ambient temperature and seasonal changes
Dose-response relationship between sports activity and musculoskeletal pain in adolescents.
Physical activity has multiple health benefits but may also increase the risk of developing musculoskeletal pain (MSP). However, the relationship between physical activity and MSP has not been well characterized. This study examined the dose-response relationship between sports activity and MSP among adolescents. Two school-based serial surveys were conducted 1 year apart in adolescents aged 12 to 18 years in Unnan, Japan. Self-administered questionnaires were completed by 2403 students. Associations between time spent in organized sports activity and MSP were analyzed cross-sectionally (n = 2403) and longitudinally (n = 374, students free of pain and in seventh or 10th grade at baseline) with repeated-measures Poisson regression and restricted cubic splines, with adjustment for potential confounders. The prevalence of overall pain, defined as having pain recently at least several times a week in at least one part of the body, was 27.4%. In the cross-sectional analysis, sports activity was significantly associated with pain prevalence. Each additional 1 h/wk of sports activity was associated with a 3% higher probability of having pain (prevalence ratio = 1.03, 95% confidence interval = 1.02-1.04). Similar trends were found across causes (traumatic and nontraumatic pain) and anatomic locations (upper limbs, lower back, and lower limbs). In longitudinal analysis, the risk ratio for developing pain at 1-year follow-up per 1 h/wk increase in baseline sports activity was 1.03 (95% confidence interval = 1.02-1.05). Spline models indicated a linear association (P < 0.001) but not a nonlinear association (P ≥ 0.45). The more the adolescents played sports, the more likely they were to have and develop pain.This study was supported by a Grant-in-Aid from the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan.

Trials were eligible if they were nonrandomized clinical trials. Studies included one treatment group in which aquatic exercise was applied. We searched the following databases from 2000 up to July 20, 2009: MEDLINE via PubMed, CINAHL, and Ichushi-Web.Results: Twenty-one trials met all inclusion criteria. Languages included were English (N = 9), Japanese (N = 11), and Korean (N = 1). Target diseases were knee and/or hip osteoarthritis, poliomyelitis, chronic kidney disease, discomforts of pregnancy, cardiovascular diseases, and rotator cuff tears. Many studies on nonspecific disease (healthy participants) were included. All studies reported significant effectiveness in at least one or more outcomes. However results of evaluations with the TREND and CLEAR-NPT checklists generally showed a remarkable lack of description in the studies. Furthermore, there was the problem of heterogeneity, and we were therefore not able to perform a meta-analysis.Conclusion: Because there was insufficient evidence on aquatic exercise due to poor methodological and reporting quality and heterogeneity of nRCTs, we were unable to offer any conclusions about the effects of this intervention. However, we were able to identify problems with current nRCTs of aquatic exercise, and propose a strategy of strengthening study quality, stressing the importance of study feasibility as a future research agenda objective.Keywords: aquatic exercise, systematic review, nonrandomized controlled trials 
Using Devices to Assess Physical Activity and Sedentary Behavior in a Large Cohort Study: The Women’s Health Study
In recent years, it has become feasible to use devices for assessing physical activity and sedentary behavior among large numbers of participants in epidemiologic studies, allowing for more precise assessments of these behaviors and quantification of their associations with health outcomes. Between 2011–2015, the Women’s Health Study (WHS) used the Actigraph GT3X+ device to measure physical activity and sedentary behavior over seven days, during waking hours, among 17,708 women (Mage, 72 years) living throughout the United States. Devices were sent to and returned by participants via mail. We describe here the methods used to collect and process the accelerometer data for epidemiologic data analyses. We also provide metrics that describe the quality of the accelerometer data collected, as well as expanded findings regarding previously published associations of physical activity or sedentary behavior with all-cause mortality during an average follow-up of 2.3 years (207 deaths). The WHS is one of the earliest “next generation” epidemiologic studies of physical activity, utilizing wearable devices, in which long-term follow-up of participants for various health outcomes is anticipated. It therefore serves as a useful case study in which to discuss unique challenges and issues faced
An evidence-based assessment of the impact of the Olympic Games on population levels of physical activity
Pre-Olympic Games predictions commonly include an increase in population-based physical activity in the host city, as often stated in the bid, but the post-Olympic Games effects on physical activity have not been summarised. In this Series paper, we aim to do the following: examine mentions of a physical activity legacy in pre-Olympic bid documentation; analyse existing physical activity surveillance data collected before, during, and after the Olympic Games in hosting areas around the world; and evaluate Google Trends data surrounding the London 2012 Olympic Games as a case study of community interest in the topic of exercise during the time of the Olympic Games. Before 2007, little mention of physical activity was made in pre-Olympic Games documentation, but, after that, most documents had targets for population physical activity or sports participation. The synthesis of available surveillance data indicates that there was no change in the prevalence of physical activity or sports participation, except for the 2008 Summer Olympics in Beijing and the 1998 Winter Olympics in Nagano; although, the increase in participation in Nagano might not be attributable to the Olympic Games since there was no change in participation in winter sports. The Google Trends data showed an acute spike in searches with the term “Olympic” immediately associated with the London Olympic Games period and showed a sustained peri-Olympic increase in searches with the term “exercise”. By themselves, the Olympic Games have not improved population-wide physical activity but might be an important missed public health opportunity. Such a legacy will require strategic planning and partnerships across the International Olympic Committee and the Olympic, sport, and public health agencies and a thorough evaluation framework implemented throughout the pre-Olympic Games and post-Olympic Games period in the host country
Advocating for implementation of the Global Action Plan on Physical Activity: challenges and support requirements
Background: There is limited understanding of the challenges experienced and supports required to aid effective advocacy of the Global Action Plan on Physical Activity (GAPPA). The purpose of this study was to assess the challenges experienced and supports needed to advocate for the GAPPA across countries of different income levels. Methods: Stakeholders working in an area related to the promotion of physical activity were invited to complete an online survey. The survey assessed current awareness and engagement with the GAPPA, factors related to advocacy, and the perceived challenges and supports related to advocacy for implementation of the GAPPA. Closed questions were analyzed in SPSS, with a Pearson’s chi-square test used to assess differences between country income level. Open questions were analyzed using inductive thematic analysis. Results: Participants (n = 518) from 81 countries completed the survey. Significant differences were observed between country income level for awareness of the GAPPA and perceived country engagement with the GAPPA. Challenges related to advocacy included a lack of support and engagement, resources, priority, awareness, advocacy education and training, accessibility, and local application. Supports needed for future advocacy included guidance and support, cooperation and alliance, advocacy education and training, and advocacy resources. Conclusions: Although stakeholders from different country income levels experience similar advocacy challenges and required supports, how countries experience these can be distinct. This research has highlighted some specific ways in which those involved in the promotion of physical activity can be supported to scale up advocacy for the GAPPA. When implementing such supports, consideration of regional, geographic, and cultural barriers and opportunities is important to ensure they are effective and equitable

背景 : 本研究の目的は,転倒予防自己効力感とHDLコレステロール及び身体能力との関連性を調べることであった。方法 : 対象者は山梨県小菅村に在住する65歳以上の高齢者339名で,本調査には132名(38.9%)が参加した。移動能力として10m全力歩行,最大一歩幅,40cm踏台昇降を,バランス能力としてつぎ足歩行を測定した。血液性状の中で,主要なアウトカムとして,HDLコレステロールを用いた。転倒予防自己効力感は,10項目,4リッカートスケールからなる質問紙で評価した。研究デザインは,転倒恐怖の有無による2群間比較の横断研究である。結果 : 転倒予防自己効力感とHDLコレステロールの間に有意な関連はなかったが,転倒予防自己効力感が低い群では有意に移動能力が低かった。また,膝痛や腰痛を伴う男性では,転倒予防自己効力感が低かった。結論 : 自己効力感とHDLコレステロールとの関連は認められなかったが,本研究は地域在住で独立生活を営む高齢者に限定されているため,今後,良くデザインされた大規模な観察研究が必要だと考えられた。Background : The aim of the current study was to clarify relationships between self-efficacy and high-density lipoprotein cholesterol (HDL-C) and physical strength.Methods : Target participants were 339 elderly residents aged 65 years or older from Kosuge Village, Yamanashi Prefecture in Japan. One hundred and thirty two persons participated in the study (38.9%). Outcome measurements included the 10-m walking time, the maximal step length and 40-cm step test as moving ability, the tandem gait as balance ability, and HDL-C. Fall-prevention self-efficacy (FPSE) was evaluated using a questionnaire that examined 10 items (actions) and 4 Likert scale. A total of 40 points could be awarded. This research design was a cross-sectional study that divided the elderly into two groups by the existence of a fear of falling.Results : Although there was no significant relationship between fall-prevention self-efficacy and HDL-C, we demonstrated that a group with poor self-efficacy had significantly deteriorated moving ability and that only one male participant with knee pain and/or lumbago exhibited poor self-efficacy.Conclusions : We could not find significant relationships between self-efficacy and HDL-C. But this study is limited to the independent elderly people in a local area, and further studies should be conducted to detect the relationships

本研究は,横断研究により,女性介護者における腰痛との関連要因を明らかにすることを目的とした。4カ所の特別養護老人ホームに勤務する女性介護職員88人を対象として,腰痛の有無,経験年数,Body Mass Index(BMI),握力,長座体前屈,指床間距離(Finger-Floor Distance : FFD),抑うつ自己評価スコア(the Center for Epidemiologic Study Depression Scale : CES-D),SF-8による身体的健康度(Physical Health Score : PHS)と精神的健康度(Mental Health Score : MHS),疲労の自覚症状を調査した。腰痛の有無を目的変数とし,その他の変数を説明変数とした多重ロジスティック回帰分析を行った。49人(55.7%)が,慢性的な腰痛を訴えていた。多重ロジスティック回帰分析の結果,腰痛の発生は,身長がオッズ比(OR)1.12,95%信頼区間(95%CI)1.02-1.23,SF-8による身体的健康度(PHS)が,OR : 0.89(95%CI : 0.86-0.97),精神的健康度(MHS)がOR : 0.90(95%CI : 0.81-0.99)で有意であった。本研究は,身長が高いことは中腰姿勢を助長し,腰痛を起こす原因になるかもしれないこと,身体・精神的な健康の程度は,腰痛と関係があることが明らかになった。今後,交代勤務に伴う睡眠障害や慢性疲労との関連性も含めて検討すべきであることが示唆された。The objective of this cross-sectional study was to reveal the actual conditions and related factors of low back pain among female caregivers in special nursing homes for the elderly.The participants were 88 female caregivers in four facilities for the elderly. We surveyed the existence of low back pain, employment period, Body Mass Index (BMI), grip power, sitting forward flexion, Finger-Floor Distance (FFD), the Center for Epidemiologic Study Depression Scale (CES-D), Physical Health Score (PHS) and Mental Health Score (MHS) by using SF-8 and subjective symptoms of fatigue. Multinomial logistic regression model was used to investigate how far low back pain was related to mental and physical health status, flexibility, power, employment period, and BMI.55.7% (N=46) of the participants notified the presence of chronic lumbago. The result of multinomial logistic regression model showed that the existence of low back pain was significant in the following variables : 1) Odds ratio (OR)=1.12 (95% confidence interval : 95%CI=1.02-1.23) for height, 2) OR=0.89 (95% CI=0.81-0.97) for PHS, 3) OR=0.90 (95% CI=0.81-0.99) for MHS.Our findings suggest that height may reinforce a half-crouching position, thus it can be a cause of low back pain, and that the degree of physical and mental health is related to low back pain. It was also suggested that lumbago prevention and/or reduction strategy should include the relevance of sleep interruption and chronic fatigue with shift work when this problem is examined in future

Strength Training and All‐Cause, Cardiovascular Disease, and Cancer Mortality in Older Women: A Cohort Study
Background: Few data exist on the association between strength training and mortality rates. We sought to examine the association between strength training and all‐cause, cardiovascular disease, and cancer mortality. Methods and Results: Beginning in 2001 to 2005, 28 879 women throughout the United States (average baseline age, 62.2 years) from the Women's Health Study who were free of cardiovascular disease, diabetes mellitus, and cancer reported their physical activities, including strength training. During follow‐up (average, 12.0 years) through 2015, investigators documented 3055 deaths (411 from cardiovascular disease and 748 from cancer). After adjusting for covariables, including aerobic activity, time in strength training showed a quadratic association with all‐cause mortality (P=0.36 for linear trend; P1.00 for ≥146 min/wk of strength training. However, confidence intervals were wide at higher levels of strength training. Conclusions: Time in strength training showed a J‐shaped association with all‐cause mortality in older women. A moderate amount of time in strength training seemed beneficial for longevity, independent of aerobic activity; however, any potential risk with more time (≈≥150 min/wk) should be further investigated
