New research into physical activity suggests that it is no longer sufficient just to meet minimum levels recommended by health guidelines in order to reduce cardiovascular risk. Both physical inactivity and sedentary behavior have their own health hazards and need to be addressed separately, in order to explore their different deleterious mechanisms. The aim of this review was to define and to characterize both concepts, and their relationship with major non-communicable chronic diseases. A PubMed database search was undertaken, using the following key words: physical activity, physical inactivity, sedentarism, sedentary behavior, and non-communicable chronic disease. This literature review provides an updated view on physical inactivity and sedentary behavior, and reevaluates their prevalence and association with major non-communicable chronic disease.

OBJECTIVE: This study aimed to investigate clinical factors contributing to the low physical activity (PA) of patients with chronic schizophrenia. METHODS: PA was measured in 50 outpatients with chronic schizophrenia using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Psychopathology, psychosocial functioning, and extrapyramidal symptoms were assessed using the 18 item-Brief Psychiatric Rating Scale (BPRS-18), Global Assessment of Functioning (GAF), and Drug-Induced Extrapyramidal Symptom Scale (DIEPSS), respectively. We examined differences in these clinical variables between “inactive,”“minimally active,” and “health enhancing physical activity” groups. Linear regression analysis was used to examine the clinical factors explaining low PA levels in patients with schizophrenia. RESULTS: Subjects spent an average of 130.18±238.89 min/wk on moderate/vigorous-intensity PA and only 26% of them met the recommended PA guideline of 150 minutes of at least moderate PA per week. The inactive group showed significantly higher BPRS-18 and DIEPSS scores, and a lower GAF score than the other groups. Linear regression analysis showed that DIEPSS scores independently explained the amount of total PA (p=0.001) and time spent being sedentary (p=0.028). CONCLUSION: This study provides preliminary evidence that extrapyramidal symptoms could be a major impediment to the PA of patients with schizophrenia.

This study is designed to check whether everyday-life stair climbing, which is a low-cost and readily accessible form of exercise, is effective for reducing overweight of sedentary people in various health indicators. We selected four overweight people and measured body weight, body fat percentage, muscle quantity, pulmonary function, lower-extremity strength and volume of thigh muscle and fat. After 3-week exercise of climbing stairs in more than 5 minutes twice a day, same procedures were taken. Body weight was reduced by 3.35 kg on average (standard deviation [SD], 0.79), and body fat mass by 2.53 kg (SD, 1.36). Lower extremity strength improved about 5%, and slight loss of thigh fat (right 3.2%; left 13.4%) was observed. However, pulmonary function and muscle quantity did not grow significantly. Although only four people may not be representative as targets, but it is suggested that stair climbing has sufficient utility as an easily accessible exercise.

OBJECTIVES: This study measures serum prostate-specific antigen (PSA) levels in tire-manufacturing workers, and attempts to find occupational or non-occupational factors that related to their PSA levels. METHODS: A total of 1,958 healthy male workers (1,699 were production workers and 259 were office workers) took PSA measurement for analysis. RESULTS: After adjusting for age, body mass index, hypertension, regular exercise, alcohol drinking and smoking, which were significantly related to serum PSA levels or known related factors of serum PSA levels, the geometric mean PSA levels were significantly high in the office workers (p = 0.017), the older age group (p < 0.001), the group with hypertension (p = 0.046) and the group of individuals that do not exercise regularly (p = 0.015) and the office workers were more likely to have a serum PSA level of > or =4.0 (OR 7.73, 95% CI: 2.78-21.46) or 2.5 ng/mL (OR 2.74, 95% CI: 1.49-5.08). After stratifying by age and adjusting aforementioned covariates, office workers 50 years of age and older had the significantly higher geometric mean PSA levels (p = 0.017) and were more likely to have a serum PSA level of > or =4.0 ng/mL (OR 12.90, 95% CI: 3.65-45.64) or 2.5 ng/mL (OR 3.90, 95% CI: 1.64-9.25) than production workers 50 years of age and older. CONCLUSIONS: This study showed that serum PSA levels were significantly higher among the group with hypertension or the group of individuals that did not exercise regularly or group of office workers who were considered to have lesser physical activities.

The purpose of this study is to evaluate the effect of lumbar stabilization exercise on lumbosacral region angle, lumbar strength, lower muscle strength, physical fitness, and low back pain of sedentary women. Twenty females who spend more than 6 hours a day as sedentary at working were recruited. The subjects were assigned to two different groups which are exercise group (n=10) and non-exercise group (n=10). Exercise program was consisted with Swiss ball and lumber stability exercise, and it was performed 60 min/day and 3 times/wk for 8 weeks. Two-way analysis of variance was conducted to analyze experimental data. As a result, there was no significant difference between groups in lumbar lordosis angle and lumbar sacral angle. However, Isometric lumbar extension strength, isokinetic knee flexion and extension peak torque in angular velocity were significantly different between groups, and the pain was reduced. To conclude, this study identified the effectiveness of lumbar stabilization exercise on lumbar muscular, strength, Sargent jump, sit and reach test and reduced pain.

The incidence of type 2 diabetes mellitus is increasing rapidly worldwide, primarily because of increases in obesity and decreases in physical activity. Type 2 diabetes is one of the leading problems for the health-care system. In South Korea type 2 diabetes affects approximately 7~8% of adults. Some risk factors of type 2 diabetes mellitus such as overweight, nutritional imbalance, and a sedentary lifestyle are reversible. To prevent type 2 diabetes two approaches are usually adopted. One is population strategy that is aimed at preventing obesity, and the other is high-risk strategy to prevent and delay the development of type 2 diabetes in high risk groups. Prevention of type 2 diabetes is backed by many research evidences like Finnish Diabetes Prevention Study (Finnish DPS) and Diabetes Prevention Program (DPP) of USA. In this article I discuss the results of Finnish DPS and DPP, and to propose the prevention strategy in South Korea.

BACKGROUND: Although obesity and health-related quality of life (HRQOL) in elderly are well known to be associated with obesity and sitting time, it is unclear whether effect of sedentary lifestyle on HRQOL is affected by body mass index (BMI) or not. So we analyzed the relationship between sitting time and HRQOL according to BMI groups in elderly Korean. METHODS: Participants aged over 60 from the 6th Korea National Health and Nutrition Examination Survey (2014 and 2015) were included. Participants were classified as normal weight and overweight/obese groups. Mean sitting times were compared between groups according to the EuroQol 5 dimension (EQ-5D) And logistic regression analyses were performed. RESULTS: Men with mobility, usual activity, or pain/discomfort domain problem had longer sitting time. Women with a problem in every domain had longer sitting time. Overweight/obese women with problem showed longer sitting time. Odds ratios (ORs) of mobility, usual activity, pain or discomfort, and low EQ-5D score domain were increased regardless of BMI groups in men. But, ORs of all domains were increased only in overweight/obese group in women. CONCLUSIONS: In elderly Korean, prolonged sitting time associated with decreased HRQOL. Impaired HRQOL is associated with increased sitting time regardless of BMI in men. But only overweight/obese group showed association between prolonged sitting time and impaired HRQOL in women. These results represents that decrease in quality of life according to the increase of the sitting time differs according to the BMI in elderly Korean women.

OBJECTIVETo find out the current situation of physical activity and its influencing factors among Chinese primary and middle school students.

METHODSA total of 166 812 students aged 9 - 18 finished the questionnaires of physical activities and lifestyle behaviors who were selected from "2010 National Physical Fitness and Health Surveillance". The subjects were sampled by stratified cluster sampling method in 30 provinces (autonomous regions, municipalities) except Tibet. The physical activity for a total of at least 60 minutes per day, attitudes on physical activity, parents' supports toward physical activity of children, development of school physical education, the schoolwork burden and sedentary lifestyle were all analyzed. Logistic regression was used to analyze the association between the physical activity for a total of at least 60 minutes per day and individual, family, school and sedentary behavior.

RESULTSA total of 22.7% (37 867/166 757) of primary and middle school students aged 9 - 18 had been physically active doing any kind of physical activity for a total of 60 minutes or more per day, the prevalence was higher among male (25.4%, 21 086/83 159) than female (20.1%, 16 781/83 598) students (P < 0.05). In the 9 - 12 age group, the prevalence was higher among urban (37.6%, 5 980/15 912) than rural (32.0%, 4 917/15 375) students (P < 0.05), but in the 16 - 18 age group, the case was opposite. The prevalence of doing physical activity for a total of 60 minutes or more per day among students who liked physical education (23.7%, 11 866/50 073), were willing to participate in the extracurricular sports activities (23.2%, 13 460/57 907), and were willing to participate long running exercise (26.9%, 9 185/34 153) was higher than those who dislike physical education (15.9%, 589/3705), were not willing to participate in the extracurricular sports activities (15.9%, 567/3565), and were not willing to participate long running exercise (12.1%, 2 246/18 493), respectively. The prevalence was higher among students whose parents supported their physical activity (20.4%, 15 148/74 312) than those students without parents' support (17.5%, 1626/9270) (P < 0.05). And the prevalence was higher among students whose parents often took part in the physical activity (22.7%, 12 864/56 769) than those students whose parents did not (14.6%, 3 906/26 780) (P < 0.05). Logistic regression analysis (adjusted sex, age and urban or not) demonstrated that variables associated with physical activity for a total of 60 minutes or more per day were the initiative will on the physical activity and parental physical activity (OR: 1.478, 95%CI: 1.398 - 1.562). The students without adequate physical education class in school were less likely to do physical activity for a total of 60 minutes or more per day than those who with adequate physical education class in school (OR: 0.536, 95%CI: 0.523 - 0.550), and the students in the school with the phenomenon of "crowding out" or "no" physical education were less likely to do physical activity for a total of 60 minutes or more per day than those whose school without these with phenomenon (OR: 0.712, 95%CI: 0.666 - 0.761). The heavy homework burden (OR: 0.926, 95%CI: 0.899 - 0.953) and long homework time (OR: 0.879, 95%CI: 0.853 - 0.906) were reversely related to the physical activity.

CONCLUSIONThe prevalence of having been physically active for a total of 60 minutes per day in Chinese students is still low. The strong initiative will on the physical activity, parental physical activity, and better school sports atmosphere are good for students to carry out physical activity, and the students with the heavy homework burden and long homework time are less likely to take part in the physical activity.

OBJECTIVETo assess the association between physical exercise and erectile function in young and middle-aged men.

METHODSUsing Paffenbarger Physical Activity Questionnaire (PPAQ) and IIEF-15, we conducted an investigation among 30- to 45-year-old male outpatients at the clinic of urology. Based on the physical activity described in PPAQ, the patients were divided into a sedentary group (≤ 1,400 Kcal/wk) and an exercise group (> 1,400 Kcal/wk).

RESULTSThe total score on IIEF-15 was signifi- cantly higher in the exercise group than in the sedentary group (62.2 vs 54.4), and so were the scores on the domains of erectile func- tion (26.4 vs 23.3), sexual desire (7.8 vs 6.9), orgasmic function (9.0 vs 8.3), intercourse satisfaction (11.5 vs 9.6), and overall satisfaction (7.5 vs 6.3) (all P < 0.05).

CONCLUSIONIncreased physical activity is associated with better sexual function in young and middle-aged men.
