RESUMEN
Low-education women, a substantially older population, are subject to increased risks of metabolic syndrome and consequent cardiometabolic diseases; early detection and effective management were urgently needed. Ninety-nine women with metabolic syndrome, age 61 and education ≤ 6 years, from four community units were randomly assigned to either a self-management intervention (n = 51) or a control arm (n = 48). The intervention consisted of five dimensions, physical activity and diet modifications (daily exercise classes and two nutrition courses), goal setting, coaching and peer support, problem-solving, and self-monitoring. The control arm received an education leaflet. Assessments were performed at baseline, six months, and 18 months. Compared with the control, the intervention participants improved the overall rate of meeting the recommended servings for six health foods, including vegetables, dairy products, and nuts (except whole grains, fruits, and protein); the rate of meeting regular leisure-time physical activity; and criteria biomarkers-waist circumference, fasting blood glucose, high-density lipoprotein cholesterol (except blood pressure and triglycerides); as well as body weight and body mass index; consequently decreased the number of risk factors and rate of metabolic syndrome. In conclusion, the multidimensional self-management intervention improved physical activity, healthy eating, and metabolic syndrome risks among low-education women with metabolic syndrome.

For facilitating risk communication in clinical management, such a ratio-based measure becomes easier to understand if expressed as a loss of life expectancy. The cohort, consisting of 543,410 adults in Taiwan, was recruited between 1994 and 2008. Health risks included lifestyle, biomarkers, and chronic diseases. A total of 18,747 deaths were identified. The Chiang's life table method was used to estimate a loss of life expectancy. We used Cox regression to calculate hazard ratios (HRs) for health risks. The increased mortality from cardio-metabolic risks such as high cholesterol (HR=1.10), hypertension (HR=1.48) or diabetes (HR=2.02) can be converted into a loss of 1.0, 4.4, and 8.9 years in life expectancy, respectively. The top 20 of the 30 risks were associated with a loss of 4 to 10 years of life expectancy, with 70% of the cohort having at least two such risk factors. Smoking, drinking, and physical inactivity each had 5-7 years loss. Individuals with diabetes or an elevated white count had a loss of 7-10 years, while prolonged sitting, the most prevalent risk factor, had a loss of 2-4 years. Those with diabetes (8.9 years) and proteinuria (9.1 years) present at the same time showed a loss of 16.2 years, a number close to the sum of each risk. Health risks, expressed as life expectancy loss, could facilitate risk communication. The paradigm shift in expressing risk intensity can help set public health priorities scientifically to promote a focus on the most important ones in primary care.

Widowhood has been increasingly encountered because of increasing longevity of women, often characterized by social stigmatization and poor physical and mental health. However, applied research to overcome its adversity has been quite limited. The goal of this study is to explore the role of physical activity in improving the health of widows.A cohort of 446,582 adults in Taiwan who successively participated in a comprehensive medical screening program starting in 1994, including 232,788 women, was followed up for mortality until 2008. Each individual provided detailed health history, and extensive lab tests results.The number of widows increased with time trend. Every other woman above age 65 was a widow (44%). Widows were less active, more obese, and smoked and drank more, had sleep problems, were more depressed with taking sedatives or psychoactive drugs, leading to more suicides. In the global development of health policies by World Health Organization (WHO), physical activity is one of the main factors to reverse poor health. The poor health of inactive widow was mitigated when becoming fully active in this study. Exercise not only reduced the observed 18% increase in all-cause mortality, but also gained 4 years and as much as 14% mortality advantage over the married but inactive. More importantly, becoming physically active energized their mental status, improved sleep quality and quantity, reduced depressions and the need for psychoactive drugs, and increased socialization circles.Widows, a rapidly growing and socially stigmatized group, suffered from social and financial inequality and tended to develop poorer health. Sustained physical activity could be one of the ways for them to overcome and reverse some of the physical and mental adversities of widowhood, and improve their quality and quantity of life.

OBJECTIVE: To assess the benefits of regular exercise in reducing harms associated with betel quid (BQ) chewing. METHODS: The study cohort, 419,378 individuals, participated in a medical screening program between 1994 and 2008, with 38,324 male and 1,495 female chewers, who consumed 5-15 quids of BQ a day. Physical activity of each individual, based on "MET-hour/week", was classified as "inactive" or "active", where activity started from a daily 15 minutes/day or more of brisk walking (≥3.75 MET-hour/week). Hazard ratios for mortality and remaining years in life expectancy were calculated. RESULTS: Nearly one fifth (18.7%) of men, but only 0.7% of women were chewers. Chewers had a 10-fold increase in oral cancer risk; and a 2-3-fold increase in mortality from lung, esophagus and liver cancer, cardiovascular disease, and diabetes, with doubling of all-cause mortality. More than half of chewers were physically inactive (59%). Physical activity was beneficial for chewers, with a reduction of all-cause mortality by 19%. Inactive chewers had their lifespan shortened by 6.3 years, compared to non-chewers, but being active, chewers improved their health by gaining 2.5 years. The improvement, however, fell short of offsetting the harms from chewing. CONCLUSIONS: Chewers had serious health consequences, but being physically active, chewers could mitigate some of these adverse effects, and extend life expectancy by 2.5 years and reduce mortality by one fifth. Encouraging exercise, in addition to quitting chewing, remains the best advice for 1.5 million chewers in Taiwan.

OBJECTIVE: Even with the 2008 physical activity guidelines for Americans and the strong epidemiological evidence, physicians are not routinely emphasizing the importance of exercise. We try to explore an innovative way to communicate the benefits of physical activity in a term familiar to patients. METHODS AND RESULTS: A cohort of 470,â163 adults from a medical screening program in Taiwan were recruited between 1994 and 2008. Their vital status was followed up by matching with the National Death File. Individuals were classified as 'inactive', 'low active', or 'fully active', with 'fully active' meeting the current exercise recommendation of 150â min per week or more. Cox proportional model was used to calculate the hazard ratio. More than one-half of the cohort was inactive (54%), with one-quarter fully active (24%). One in seven was hypertensive (14%), defined as SBP at least 140â mmHg. Among the hypertensive individuals, mortality risks were increased by 37% for the inactive. Inactive individuals had higher all-cause mortality than active ones across all blood pressure (BP) levels. At 110-119 âmmHg, the inactive had a risk as high as the risk at 155 âmmHg, an increased mortality risk equivalent to a risk of BP increase of 41.2âmmHg. CONCLUSION: The mortality risk of being inactive was equivalent to an increase of around 40 âmmHg in SBP or 20 âmmHg in DBP, a number relevant to hypertensive patients. Appreciating this relationship may convince the inactive to start exercising, a behavior as important as controlling BP.

BACKGROUND: High serum uric acid (sUA) has been associated with increased mortality risks, but its clinical treatment varied with potential side effects. The role of physical activity has received limited attention. METHODS: A cohort, consisting of 467â 976 adults, who went through a standard health screening programme, with questionnaire and fasting blood samples, was successively recruited between 1996 and 2008. High sUA is defined as uric acid above 7.0â mg/dL. Leisure time physical activity level was self-reported, with fully active defined as those with 30â min per day for at least 5â days a week. National death file identified 12â 228 deaths with a median follow-up of 8.5â years. Cox proportional model was used to analyse HRs, and 12 variables were controlled, including medical history, life style and risk factors. FINDINGS: High sUA constituted one quarter of the cohort (25.6%). Their all-cause mortality was significantly increased [HR: 1.22 (1.15-1.29)], with much of the increase contributed to by the inactive (HR: 1.27 (1.17-1.37)), relative to the reference group with sUA level of 5-6â mg/dL. When they were fully active, mortality risks did not increase, but decreased by 11% (HR: 0.89 (0.82-0.97)), reflecting the benefits of being active was able to overcome the adverse effects of high sUA. Given the same high sUA, a 4-6â years difference in life expectancy was found between the active and the inactive. CONCLUSIONS: Physical activity is a valuable alternative to pharmacotherapy in its ability to reduce the increases in mortality risks from high sUA. By being fully active, exercise can extend life span by 4-6â years, a level greater than the 1-4â years of life-shortening effect from high sUA.

BACKGROUND: The health benefits of leisure-time physical activity are well known, but whether less exercise than the recommended 150 min a week can have life expectancy benefits is unclear. We assessed the health benefits of a range of volumes of physical activity in a Taiwanese population. METHODS: In this prospective cohort study, 416,175 individuals (199,265 men and 216,910 women) participated in a standard medical screening programme in Taiwan between 1996 and 2008, with an average follow-up of 8·05 years (SD 4·21). On the basis of the amount of weekly exercise indicated in a self-administered questionnaire, participants were placed into one of five categories of exercise volumes: inactive, or low, medium, high, or very high activity. We calculated hazard ratios (HR) for mortality risks for every group compared with the inactive group, and calculated life expectancy for every group. FINDINGS: Compared with individuals in the inactive group, those in the low-volume activity group, who exercised for an average of 92 min per week (95% CI 71-112) or 15 min a day (SD 1·8), had a 14% reduced risk of all-cause mortality (0·86, 0·81-0·91), and had a 3 year longer life expectancy. Every additional 15 min of daily exercise beyond the minimum amount of 15 min a day further reduced all-cause mortality by 4% (95% CI 2·5-7·0) and all-cancer mortality by 1% (0·3-4·5). These benefits were applicable to all age groups and both sexes, and to those with cardiovascular disease risks. Individuals who were inactive had a 17% (HR 1·17, 95% CI 1·10-1·24) increased risk of mortality compared with individuals in the low-volume group. INTERPRETATION: 15 min a day or 90 min a week of moderate-intensity exercise might be of benefit, even for individuals at risk of cardiovascular disease.

AIMS: To explore the effects of exercise programme on glycosylated haemoglobin and peak oxygen uptake in children and adolescents with type 1 diabetes mellitus. BACKGROUND: Regular exercise has been shown to be effective in blood glucose control, which includes improving glucose tolerance and insulin sensitivity, decreasing glycosylated haemoglobin levels and improving cardiorespiratory fitness. DESIGN: Quasi-experimental design with a twelve-week home-based aerobic exercise programme. METHOD: Twenty-eight participants completed the study: 12 in the home-based exercise group, 11 in the non-exercise control group and five in the self-directed exercise group. A mixed model was used to capture longitudinal change in glycosylated haemoglobin levels. RESULTS: The home-based aerobic exercise group showed no significant effect on glycemic control and peak oxygen uptake in this study across assessment times. However, a group difference in glycosylated haemoglobin levels at the nine-month follow-up was significant (general linear model: F = 4.06, p = 0.03). A Bonferroni test indicated that glycosylated haemoglobin levels in the home-based exercise group were higher than in the self-directed exercise group (p < 0.05) and higher in the control group than in the self-directed exercise group (p < 0.05) at the nine-month follow-up. Home-based aerobic exercise showed no significant effect on peak oxygen uptake in this study. CONCLUSIONS: A three-month home-based aerobic exercise programme has no significant effect on glycosylated haemoglobin and peak oxygen uptake levels in children with type 1 diabetes mellitus. RELEVANCE TO CLINICAL PRACTICE: Our exercise programme has designed that children can practice exercise at home and is a viable component of self-care intervention to improve patient's self-care skill and diabetes care control. However, how to encourage patients to adhere the exercise programme is a challenge for health care providers.

Leisure-time physical activity (LTPA) has been closely related to health improvement. The under-appreciation for energy output by nutritionists stems in part from limited data expressed in caloric equivalent. We converted the frequency, duration, and intensity of LTPA, reported from 15,390 adults in the Taiwan National Health Interview Survey 2001, into kilocalories (kcal). Half of Taiwanese adults admit to no LTPA. Women, lower education or income, younger age, smokers and chewers of betel quid; exercised significantly less than their counterparts. Less than 1/5 (18.9%) of the population in Taiwan was physically active at >or=750 kcal/week, and only 1/7 (13.9%) reached a more desirable goal of >or=1,000 kcal/week, compared with 1/3 in the U.S. The most disconcerting finding was the Taiwan unique U-shaped prevalence for males, with the 25-44 age group being the least active, >or=65 age group being the most active; and S-shaped for females, lowest at age 18-24 years and highest at the two older groups (45-64 and >or=65 years). LTPA was under-appreciated, particularly among the most productive work force (25-44-year group), who exercised with a prevalence only 1/4 of their U.S. counterparts. Expressing LTPA in kcal makes direct comparison easier. Invoking a goal of >or=750 kcal/week for Asians, attainable by exercising 4 hours/week, can facilitate nutritionists in assessing LTPA adequacy. Currently, 4/5 of adults in Taiwan failed to reach this goal. Recognizing the concept of cumulative energy expenditure, in contrast to disciplined daily work for 5 or more days, will encourage the infrequent exercisers such as "weekend warriors" to continue with their activities.
