Physical inactivity has reached epidemic levels in developed countries and is being recognized as a serious public health problem. Recent evidence shows a high percentages of individuals worldwide who are physically inactive, i.e. do not achieve the WHO's present recommendation of 150 minutes of moderate to vigorous intensity per week in addition to usual activities. Living in sedentary lifestyle is one of the leading causes of deaths and a high risk factor for several chronic diseases, like cancer, cardiovascular disease, diabetes type 2, and osteoporosis. This article summarizes evidence for relative risk of the civilization diseases attributable to physical inactivity and the most important conclusions available from the recent investigations computing the economic costs specific to physical inactivity. The findings provide health and economic arguments needed for people to understand the meaning of a sedentary lifestyle. This may be also useful for public health policy in the creation of programmes for prevention of physical inactivity.

AIn this paper we introduce and study a multivariate notions of mean inactivity time (MIT) functions. Basic properties of these functions are derived and their relationship to the multivariate conditional reversed hazard rate functions is studied. A partial ordering, called MIT ordering, of non-negative random vectors is introduced and its basic properties are presented. Its relationship to reversed hazard rate ordering is pointed out. Finally, using the MIT ordering, a bivariate and multivariate notions of IMIT (increasing mean inactivity time) class is introduced and studied.

Muscle atrophy is defined as a decrease in muscle mass, cross-sectional area, and myofibrillar protein content. Causes inducing muscle atrophy may be inactivity, denervation, undernutrition and steroid. Inactivity may decrease protein synthesis and increase protein breakdown of skeletal muscle. The muscle atrophy due to inactivity was induced by bed rest, hindlimb suspension, cast, total hip replacement arthroplasty, anterior cruciate ligament reconstruction. Denervated atrophy may be induced by the loss of innervation from lower motor neuron. The atrophy was apparent in the lower limb of hemiplegic patients following ischemic stroke and in the hindlimb of ischemic stroke rats. Protein breakdown of skeletal muscle in the undernourished state results in muscle atrophy. The atrophy due to undernutrition was evident in cancer and leukemia patients and in the undernourished rats. Steroids have been used to treat allergies, inflammatory diseases, autoimmune diseases and to inhibit immune function following transplantation. Steroids may induce muscle atrophy by protein breakdown of skeletal muscle. Muscle Physiology Laboratoryat College of Nursing, Seoul National University proved that dexamethasone may induce hindlimb muscle atrophy in rats and exercise and DHEA may attenuate hindlimb muscle atrophy induced by the steroid in rats. Nurses working with patients undergoing steroid treatment need to be cognizant of steroid induced muscle atrophy. They need to assess whether muscle atrophy is being occurred during and after the steroid treatment. Moreover, they need to apply exercise and DHEA to the patients undergoing steroid treatment in order to attenuate the steroid induced muscle atrophy.

[Purpose] Many studies have observed a high prevalence of erectile dysfunction among individuals performing physical activity in less leisure-time. However, this relationship in patients with type 2 diabetic patients is not well studied. In exposure outcome studies with ordinal outcome variables, investigators often try to make the outcome variable dichotomous and lose information by collapsing categories. Several statistical models have been developed to make full use of all information in ordinal response data, but they have not been widely used in public health research. In this paper, we discuss the application of two statistical models to determine the association of physical inactivity with erectile dysfunction among patients with type 2 diabetes. [Methods] A total of 204 married men aged 20-60 years with a diagnosis of type 2 diabetes at the outpatient unit of the Department of Endocrinology at PSG hospitals during the months of May and June 2019 were studied. We examined the association between physical inactivity and erectile dysfunction using proportional odds ordinal logistic regression models and continuation ratio models. [Results] The proportional odds model revealed that patients with diabetes who perform leisure time physical activity for over 40 minutes per day have reduced odds of erectile dysfunction (odds ratio=0.38) across the severity categories of erectile dysfunction after adjusting for age and duration of diabetes. [Conclusion] The present study suggests that physical inactivity has a negative impact on erectile function. We observed that the simple logistic regression model had only 75% efficiency compared to the proportional odds model used here; hence, more valid estimates were obtained here.

Objectives: To provide basic data needed to develop national physical activity policy, this study was examined to identify the relationship among physical inactivity, physical activity, and chronic diseases. Methods: I have reviewed articles and research reports in relation to physical activity, health, and chronic disease published in national and international since 2005 through PubMed, RISS, and KISS. Results: physical activity should be the priority of public health for the prevention and management of chronic diseases as following reasons. 1) Prevalence of physical inactivity has been continuously increased. 2) There were strong evidences that sufficient physical activity could prevent and treat dozens of chronic diseases. Conclusions: Both central and local governments need to make the amount of physical activity to be increased by providing information and establishing a physical activity-friendly environment. Also, the local public health centers and the primary medical institutions are institutionally needed to counsel and prescribe every patient's exercise program at every visit.

본 연구는 비경제활동을 지속하는 장애인들의 취업의사에 영향을 미치는 요인을 파악하기 위해 2014년 장애인고용패널조사 자료에서 2년 연속 미취업상태로 확인된 총 2,255명을 대상으로 $X^2$ 검증, t분석, 로지스틱 회귀분석을 실시하였다. 비경제활동을 유지하는 장애인들의 취업의사에 영향을 주는 요인을 파악하기 위해 선행연구에서 제시한 인구학적 요인, 장애 요인, 인적자본 요인, 심리사회적 요인을 가정하여 분석하였다. 분석 결과, 인구학적 요인에서 남성이거나, 배우자가 있거나, 기초생활수급자인 비경제활동 유지 장애인일수록 높은 취업의사를 가질 확률이 상승했다. 장애 요인 중 장애차별경험의 경우, 장애차별경험이 많을수록 비경제활동 유지 장애인들의 취업의사가 높을 가능성이 상승했으나, 이러한 결과는 구직활동에 적극적일수록 장애차별경험을 많이 경험하게 된다는 상관관계 측면에서 이해해야 할 것으로 보인다. 그리고, 인적자본 요인과 심리사회적 요인 중에서 활용능력(컴퓨터, 영어구사능력, 대인관계 및 적응능력), 직업재활서비스의 직업훈련 프로그램 이용 경험, 자아존중감 등의 세부 요인이 비경제활동 유지 장애인의 취업의사에 영향을 미치는 것으로 확인되었다. 이러한 결과를 바탕으로 본 연구에서는 여성장애인 취업지원 확대, 장애인의 활용능력과 자아존중감을 향상시키는 프로그램, 장애인 직업재활서비스의 전반적 확대와 접근 편이성 개선 등을 제안하였다.

Objectives: The aim of this study was to verify relationships between light- and heavy alcohol drinking and health-risk behaviors such as smoking, inappropriate weight control, physical inactivity, and sexual activity among adolescents. Methods: The data of 68,043 adolescents in middle- and high school collected from the Korea Youth Risk Behavior Web-based Survey in 2015 were analyzed. For statistical analysis, logistic regression model was used. Results: The rate of heavy alcohol drinking increased with increasing age up to 21.5% among boys and 13.9% among girls. Among boys, heavy alcohol drinkers were at a higher risk of smoking (adjusted odds ratios [OR]=3.3, 95% confidence interval [CI]=2.8-3.8), inappropriate weight control (OR=1.7; 95% CI=1.4-2.1), having sexual intercourse (OR=3.6; 95% CI=3.0-4.2) than light drinkers. Multiple health-risk behaviors of smoking, inappropriate weight control and sexual intercourse also increased in accordance with the severity of drinking alcohol beverage compared to non-drinker. Physical inactivity was decreased among heavy drinkers compared to light drinkers (OR=0.8; 95% CI=0.7-0.9 for inactivity of moderate exercise). Similar results were observed among girls. Conclusions: Alcohol drinking especially heavy alcohol drinking among adolescents is related to other risky behaviors including smoking, inappropriate weight control, and sexual activity. To prevent health problems in adolescents, it is necessary to adopt a combined approach regarding heavy drinking and health-risk behaviors.

Objectives : The physical activity of Korean adolescents and its distribution based on social characteristics have not yet been fully assessed. This study intends to reveal the distribution of physical activity by its subgroups and offer possible explanatory variables. Methods : The 3rd Korea Youth Risk Behavior Web-based Survey was analyzed for this study. The appropriateness of physical activity was defined by Korea s Health Plan 2010 and physical inactivity was assessed independently. Family affluence scale, parents education levels, subjective economic status, grade, and school location were considered explanatory variables. All statistical analysis was conducted using SAS ver. 9.1. Results : The proportion of participants engaging in vigorous physical activity was high in males (41.6%), at a low grade (38.5%), within the high family affluence scale group (35.5%). The distribution of participants engaging in moderate physical activity showed similar patterns, but the overall proportion was lower (9.8%). Low family affluence and students with lower subjective economic status reported a higher prevalence of physical inactivity. In multiple logistic regression analysis for physical activity, significant factors included family affluence scale (p<0.05). For physical inactivity, family affluence scale, parents education levels, and subjective economic status were included as significant factors (p<0.05). Conclusions : The results suggest that the physical activity and inactivity of adolescents may be affected by socioeconomic variables, such as family affluence scale. This implies the need to take proper measures to address these socio-economic inequalities.

Objectives: This study evaluated the dietary habits and health behaviors of Korean adults according to their physical activity. Methods: Adults aged 19~64 years, who participated in the 2016~2018 National Health and Nutrition Examination Survey, were enrolled in this study. The subjects were classified into the physical inactivity group, aerobic physical activity group, strength exercise group, and combined exercise group. Results: Significant differences in skipping breakfast, frequency of eating out, dietary supplements, and alcohol drinking status were observed among physical activity groups (P < 0.001). The combined exercise group had the highest % KDRI of protein, vitamin A, thiamin, riboflavin, niacin, calcium, potassium, and iron (P < 0.001). The physical inactivity group had the highest obesity rate (35.1%), and they perceived their body image type to be obese. In the combined exercise group, 47.8% of respondents said they were in good health (P < 0.001). The health-related quality of life score of the physical inactivity group was the lowest, with a score of 0.94. The metabolic syndrome risk rate of the combined exercise group was lower at 0.62 times (95% CI, 0.51-0.75) than the physical inactivity group. Conclusions: The physical activity type was associated with metabolic syndrome. These results can be useful for supporting dietary education and physical activity programs for adults.
