Differing intensities of a midwife-led antenatal healthy lifestyle service on maternal and neonatal outcomes: A retrospective cohort study.

INTRODUCTION: Maternal obesity and excessive gestational weight gain are associated with adverse maternal and neonatal outcomes. There is uncertainty over the most effective antenatal healthy lifestyle service, with little research determining the impact of different lifestyle intervention intensities on pregnancy outcomes. METHOD: This retrospective cohort study compared pregnancy and birth outcomes in women with a body mass index of 40 or above who were offered a low intensity midwife-led antenatal healthy lifestyle service (one visit) with women who were offered an enhanced service (three visits). The primary outcome was gestational weight gain. RESULTS: There were no differences between the two healthy lifestyle service intensities (N = 682) in the primary outcome of mean gestational weight gain [adjusted mean difference (aMD) -1.1 kg (95 % CI -2.3 to 0.1)]. Women offered the enhanced service had lower odds of gaining weight in excess of Institute of Medicine recommendations [adjusted odds ratio (aOR) 0.63 (95 % CI 0.40-0.98)] with this reduction mainly evident in multiparous women. Multiparous women also gained less weight per week [aMD -0.06 kg/week (95 % CI -0.11 to -0.01)]. No overall beneficial effects were seen in maternal or neonatal outcomes measured such as birth weight [aMD 25 g (95 % CI -71 to 121)], vaginal birth [aOR 0.87 (95 % CI 0.64-1.19)] or gestational diabetes mellitus [aOR 1.42 (95 % CI 0.93-2.17)]. However, multiparous women receiving the enhanced service had reduced odds of small for gestational age [aOR 0.52 (95 % CI 0.31-0.87)]. This study was however underpowered to detect differences in some outcomes with low incidences. DISCUSSION: Uncertainty remains over the best management of women with severe obesity regarding effective interventions in terms of intensity. It is suggested that further research needs to consider the different classes of obesity separately and have a particular focus on the needs of nulliparous women given the lack of effectiveness of this service among these women.

Effect of health lifestyle on the risk of stroke: a prospective cohort study from Chongqing, China.

OBJECTIVE: To prospectively investigate the associations of healthy lifestyle factors on the risk of stroke and stroke subtypes, as studies exploring this relationship are limited in China. METHODS: The 22,661 participants in the prospective cohort study in Chongqing, China, aged 30-79 years and stroke-free at baseline completed follow-up from 2018 to 2022. We included seven healthy lifestyle factors, including non-smoking, non-excessive drinking, sufficient physical activity, healthy diet, sleep duration of 7-9 h/d, and standard range of body mass index and waist-to-hip ratio. The healthy lifestyle score was calculated based on the number of healthy lifestyle factors. RESULTS: Compared with participants who had scores ≤2, participants with scores ≥6 had an HRs (95% CIs) of 0.56 (0.34, 0.92) for total stroke and 0.53 (0.30, 0.93) for ischemic stroke. For every 1-point increase in healthy lifestyle scores, the HRs (95% CIs) for total stroke and ischemic stroke was 0.86 (0.78, 0.95) and 0.86 (0.77, 0.96), respectively. CONCLUSIONS: Maintaining multiple healthy lifestyle factors can significantly reduce the risk of stroke. As the number of healthy lifestyle factors increased, the stroke risk gradually decreased. Our findings emphasize the significance of comprehensive lifestyle interventions.

Reliability and Validity of the Health-Promoting Lifestyle Profile II Spanish Version in University Students.

AIM: The purpose of this study was to assess the reliability and validity of the Spanish version of the Health Promoting Lifestyle Profile II (HPLP-II) scale in Colombian university students. METHODS: This was a methodological study to verify reliability and construct validity. A total of 763 undergraduate university students in Cali, Colombia, agreed to participate in the study by filling out a form that included information on sociodemographic characteristics and the HPLP-II scale Spanish version. Data were collected between February and June 2021. To determine construct validity, a confirmatory factor analysis was performed, and internal consistency was determined through Cronbach's alpha. RESULTS: The confirmatory factor analysis of the proposed theoretical model showed that the goodness-of-fit indices of the scale demonstrated an acceptable level of validity nearing an excellent level of fit (χ2 = 7168.98; gl = 1268; p < 0.001; root mean square error of approximation = 0.08; normed fit index, adjusted goodness-of-fit index = 0.95). Cronbach's alpha coefficient of the scale was 0.94, and the subscales ranged from 0.68 to 0.89. CONCLUSIONS: The HPLP-II Spanish version is a valid and reliable instrument to assess the health-promoting lifestyle profile of university students.

Intermittent Fasting: Socio-Economic Profile of Spanish Citizens Who Practice It and the Influence of This Dietary Pattern on the Health and Lifestyle Habits of the Population.

Intermittent fasting (IF) is a dietary approach that has gained popularity in recent years. More and more Spanish people are following this eating pattern, which consists of alternating periods of fasting with periods of food intake. Its benefits include improved metabolic and vascular health and weight loss. OBJECTIVES: 1. To study the prevalence of IF among the Spanish population. 2. To explore how demographic factors influence the choice to adopt this dietary approach. METHODS: A descriptive cross-sectional study was conducted on the Spanish population using the NutSo-HH questionnaire, which was constructed, validated, and disseminated by the research team through a non-probabilistic snowball sampling approach, collecting socio-demographic data and nutritional, social and lifestyle habits of the population. RESULTS AND CONCLUSIONS: A valid sample of 22,181 people participated, of whom 4.59% (n = 1018) said they practiced IF. The data show that more middle-aged men than women practice IF. In addition, individuals who follow IF methods are less likely to have no control over their food intake, are less scared to gain weight and have a higher body image, but no differences were found related to unhealthy food and nights out. There were also no significant differences in terms of the level of education, income, size of municipality, or region of residence. In conclusion, a person who practices IF seems to have adopted a healthier lifestyle and social habits.

Association between Lifestyle Modification and All-Cause, Cardiovascular, and Premature Mortality in Individuals with Non-Alcoholic Fatty Liver Disease.

BACKGROUND: This study is designed to explore the correlation between multiple healthy lifestyles within the framework of "lifestyle medicine", and the mortality risk of nonalcoholic fatty liver disease (NAFLD). METHODS: The National Health and Nutrition Examination Survey (NHANES) database was employed. The analysis consisted of 5542 participants with baseline NAFLD and 5542 matched non-NAFLD participants from the database. Lifestyle information, including five low risk factors advocated by lifestyle medicine (healthy diet, vigorous physical activity, healthy sleep duration, avoiding smoking, and maintaining a non-depressed psychological status), was collected through a baseline questionnaire. Cox proportional hazards regression models and Kaplan-Meier survival curve were used to evaluate risk of mortality. In addition, subgroups were analyzed according to gender, age, body mass index and waist circumference. RESULTS: In total, 502 deaths (n = 181 deaths from cardiovascular disease (CVD)) were recorded among NAFLD participants after the median follow up duration of 6.5 years. In the multivariate-adjusted model, compared to participants with an unfavorable lifestyle (scoring 0-1), NAFLD participants with a favorable lifestyle (scoring 4-5) experienced a 56% reduction in all-cause mortality and a 66% reduction in CVD mortality. Maintaining an undepressed psychological state and adhering to vigorous exercise significantly reduced CVD mortality risk in NAFLD participants (HR, 0.64 [95% CI, 0.43-0.95]; HR, 0.54 [95% CI, 0.33-0.88]) while maintaining healthy sleep reduced premature mortality due to CVD by 31%. CONCLUSIONS: Healthy lifestyle, characterized by maintaining an undepressed mental state and healthy sleep, significantly mitigates the risk of all-cause, CVD, and premature mortality risk among NAFLD patients, with a particularly pronounced effect observed in female and obese subpopulations.

Does Serum Uric Acid Mediate Relation between Healthy Lifestyle and Components of Metabolic Syndrome?

A healthy lifestyle is related to metabolic syndrome (MetS), but the mechanism is not fully understood. This study aimed to examine the association of components of MetS with lifestyle in a Chinese population and potential mediation role of serum uric acid (SUA) in the association between lifestyle behaviors and risk of components of MetS. Data were derived from a baseline survey of the Shaanxi urban cohort in the Regional Ethnic Cohort Study in northwest China. The relationship between components of MetS, healthy lifestyle score (HLS), and SUA was investigated by logistic or linear regression. A counterfactual-based mediation analysis was performed to ascertain whether and to what extent SUA mediated the total effect of HLS on components of MetS. Compared to those with 1 or less low-risk lifestyle factors, participants with 4-5 factors had 43.6% lower risk of impaired glucose tolerance (OR = 0.564; 95%CI: 0.408~0.778), 60.8% reduction in risk of high blood pressure (OR = 0.392; 95%CI: 0.321~0.478), 69.4% reduction in risk of hypertriglyceridemia (OR = 0.306; 95%CI: 0.252~0.372), and 47.3% lower risk of low levels of HDL cholesterol (OR = 0.527; 95%CI: 0.434~0.641). SUA mediated 2.95% (95%CI: 1.81~6.16%) of the total effect of HLS on impaired glucose tolerance, 14.68% (95%CI: 12.04~18.85%) on high blood pressure, 17.29% (95%CI: 15.01~20.5%) on hypertriglyceridemia, and 12.83% (95%CI: 10.22~17.48%) on low levels of HDL cholesterol. Increased HLS tends to reduce risk of components of MetS partly by decreasing the SUA level, which could be an important mechanism by which lifestyle influences MetS.

The impacts of a healthy lifestyle on the physical and mental health status of female stroke survivors in Australia.

INTRODUCTION: This longitudinal study aimed to explore the impacts of adopting a healthy lifestyle on self-reported physical and mental health outcomes among Australian females who are living with stroke. METHODS: The study utilized data retrieved from the Australian Longitudinal Study on Women's Health's 1946-51 cohort (from survey 5 conducted in 2007 to survey 9 conducted in 2019), focusing on 531 female stroke survivors. The dependent variables for this study were self-reported physical and mental health status, whereas the independent variables were lifestyle behaviors, including physical activity, smoking, alcohol consumption, and supplement use. Generalized Estimating Equation models were employed to assess the longitudinal associations between a dependent variable and the independent and confounding variables. RESULTS: The average age of the participants was 58.1 (SD = 1.4) years in survey 5 and 70.5 years in survey 9. The longitudinal analyses revealed that stroke survivors who engaged in moderate/high levels of physical activity had significantly better physical and mental health status than their inactive or sedentary counterparts. Besides, current smokers had significantly poorer physical and mental health status than nonsmokers. In addition, risky/high-risk alcohol consumers had significantly poorer mental health status compared to no/low-risk alcohol consumers. CONCLUSIONS: Our findings suggest that post-stroke individuals can improve their physical and mental health by maintaining a healthy lifestyle. Specifically, targeted and appropriate programs and strategies are needed to promote physical activity and reduce smoking and alcohol consumption in female stroke survivors in order to optimize their overall health and quality of life.

Adverse childhood experience, adopting a healthy lifestyle in adulthood, and risk of cardiovascular diseases.

BACKGROUND: Both adverse childhood experiences (ACEs) and lifestyle factors have been associated with risk of cardiovascular diseases (CVDs) in later life, but whether and to what extent adherence to a healthy lifestyle in adulthood can offset the increased cardiovascular risk associated with ACEs is unclear. We aimed to determine whether and to what extent adopting to a healthy lifestyle in adulthood can offset the risk of CVDs in individuals according to their ACEs. METHODS: A prospective cohort study included 143,869 participants aged 38-72 years, free of CVDs at baseline from the UK Biobank. The history of ACEs was assessed using the Childhood Trauma Screener. Participants were divided into three risk groups based on ACEs: low (no ACEs), intermediate (one or two ACEs), and high (three or more ACEs). A healthy lifestyle score in adulthood was constructed as the sum of four modifiable lifestyle factors (no smoking, adequate physical activity, healthy diet, no obesity), and participants were then categorized into three groups based on this score (unfavorable [0-1 point], intermediate [2-3 points], favorable [4 points]). Cox proportional hazard models were conducted to investigate the association between ACEs, healthy lifestyle, and incident CVDs. RESULTS: During a median follow-up of 12.49 years, 13,373 incident cases of overall CVDs were identified. This included 7521 cases of coronary heart disease (CHD), 6175 cases of atrial fibrillation (AF) and 1813 cases of stroke. Individuals with high ACEs had a greater risk of incident overall CVDs (hazard ratio [HR] = 1.39, [95%CI = 1.29 to 1.50]), CHD (1.50 [1.36 to 1.65]) and AF (1.18 [1.05 to 1.33]) compared to those with low ACEs. The risk of CVDs decreased moving from unfavorable to favorable lifestyle categories (P for trend<0.001), with the lowest risk observed among individuals with a favorable lifestyle (0.70 [0.66 to 0.74] for overall CVDs, 0.69 [0.64 to 0.75] for CHD, and 0.71 [0.65 to 0.78] for AF). Participants with high ACEs and a favorable lifestyle had a 39 %, 40 % and 47 % lower risk of developing overall CVDs (0.61 [0.48 to 0.76]), CHD (0.60 [0.44 to 0.81], and AF (0.53 [0.36 to 0.77]) than those with high ACEs and an unfavorable lifestyle. CONCLUSIONS: Having a healthy lifestyle in adulthood could substantially attenuate the increased risk of overall CVDs, CHD, and AF conferred by ACEs.

[The risk factors of development of circulatory system diseases according the results of STEPS-study in Belarus in 2016-2017 and 2019-2020: what was succeeded to change?]

The article for the first time analyzes and compares data of STEPS-studies in 2016-2017 and 2019-2020 in Belarus. It demonstrates impact of organizational measures and management decisions at level of the Ministry of Health of the Republic of Belarus on monitoring indicators of main risk factors of development of non-communicable diseases based on results of the study. The prospects of impact of risk factors of development of diseases of circulatory system on levels of population morbidity is demonstrated. The STEPS-studies of 2016-2017 and 2019-2020 were carried out by the authors as coordinators for the Brest region. In Belarus, the study was part of set of the UN measures implemented by the WHO targeted to ensuring increase in standard of living and well-being of population of Belarus. In 2016-2020, Belarus implemented project "Prevention of noncommunicable diseases, promotion of a healthy lifestyle and modernization of the healthcare system in the Republic of Belarus" (BELMED), funded by the EU as international technical assistance project. Within this project with the support of the WHO, national study was organized on prevalence of main risk factors of development of non-communicable diseases (NCDs) in population of the Republic of Belarus aged 18-69 years. The article compares and demonstrates dynamics of indicators of main risk factors of development of diseases of circulatory system (BSC) according STEPS-studies of 2016-2017 and 2019-2020. It is demonstrated that organizational and managerial decisions made on the basis of large-scale studies can affect further prevalence of risk factors of NCDs in population. The problems of prospects for further increasing of incidence of BSC in the Republic of Belarus and their relationship with cardiovascular risks are also highlighted.

[The attitude of foreign students to healthy life-style and confidence to modern medicine as exemplified by students of Kursk].

The article investigates attitude of foreign students to health and a healthy lifestyle. The main practices of maintenance of health and healthy lifestyle are analyzed. The opinions of foreign students related to their health and their modes of dealing with stress in new social cultural conditions are considered. The results of sociological survey carried out in January 2024 covering students of the Kursk State Medical University - foreign students who arrived to receive higher education were chosen as the analysis base. The study established that foreign students more often associate healthy lifestyle with maintenance of mental health, healthy diet and domestic hygiene. At that, considering medicine and physician visits, percentage of respondents attributing these aspects to healthy lifestyle and themselves applying to medical workers is far lower than those giving up bad habits and maintain hygiene. The conclusion is made that it is necessary to increase awareness of foreign students about their rights to receive qualified medical care that will serve as factor increasing confidence in medical institutions and physicians.

[A healthy lifestyle of students is a resource for preserving the health of the working-age population in the near future].

The issues of acceptance and support of a healthy lifestyle by various social and age groups of the population, especially among the younger generation and youth, through the pursuit of physical, mental and social well-being remain relevant. Educational organizations, including universities, are important actors in this direction, since their students will soon become leaders in society, decision makers, as well as parents of tomorrow. According to scientists, a weak attitude towards sports, lack of time for physical education lead to a vicious circle of focusing on intellectual education, high knowledge scores, low physical abilities and physical fitness. It is emphasized that universities should have organizational systems for managing educational materials, teaching staff, as well as technologies to improve learning processes through a technology platform. Universities are strategic places to launch a wellness campaign and «have conversations¼ about healthy lifestyles and sustainable development.

A Cross-Sectional Nationwide Study of Australians' Health: Are There Differences in Health-Related Behaviors and Psychological Distress Between Teachers and Other Occupations?

BACKGROUND: Teachers' health behaviors and mental well-being are important for their chronic disease risk and reducing burnout. This study investigates the health-related behaviors and psychological distress of Australian teachers compared with other occupations. METHODS: Data from the nationally representative Australian National Health Survey (NHS) were analyzed. Employed adults (20-64 years) from 2014/2015 (n = 8455), 2017/2018 (n = 9130), and 2020/2021 (n = 5753) survey waves were included. Logistic regression, adjusted for demographics, compared health-related behaviors (eg, physical activity, diet), and psychological distress among teachers, nonteacher professionals (NTPs; eg, accountants, doctors), and other general occupations (eg, laborers, beauticians). RESULTS: After adjusting for demographics and survey wave, teachers had similar odds as NTPs for meeting physical activity (OR: 1.12, 95% CI: 0.90-1.41), vegetable intake (OR: 0.72, 95% CI: 0.52-1.00), and alcohol consumption (OR: 1.01, 95% CI: 0.83-1.22) guidelines. However, teachers exhibited higher psychological distress (OR: 1.35, 95% CI: 1.01-1.75). Elevated psychological distress levels were observed in all groups in 2020/2021, compared with pre-COVID-19. CONCLUSIONS: Compared with NTPs, teachers showed similar or better health-related behaviors, although teachers had higher levels of psychological distress. School executives and policymakers need to implement sustainable measures to prioritise teachers' mental wellbeing.

Impact of Healthy Lifestyle Factors on Life Expectancy and Lifetime Health Care Expenditure: Nationwide Cohort Study.

BACKGROUND: The association between lifestyle risk factors and the risk of mortality and chronic diseases has been established, while limited research has explored the impact of healthy lifestyle factors on lifetime health care expenditure using longitudinal individual data. OBJECTIVE: We aimed to determine the individual and combined effects of 5 healthy lifestyle factors on life expectancy and lifetime health care expenditure in Taiwan. METHODS: Using data from the National Health Interview Survey cohort, 5 healthy lifestyle behaviors were defined and analyzed: nonsmoking, avoiding excessive alcohol consumption, engaging in sufficient physical activity, ensuring sufficient fruit and vegetable intake, and maintaining a normal weight. We used a rolling extrapolation algorithm that incorporated inverse probability of treatment weighting to estimate the life expectancy and lifetime health care expenditure of the study populations with and without healthy lifestyle factors. RESULTS: A total of 19,893 participants aged ≥30 (mean age 48.8, SD 13.4) years were included, with 3815 deaths recorded during a median follow-up period of 15.6 years. The life expectancy and per capita estimated lifetime health care expenditures for the overall study population were 35.32 years and US $58,560, respectively. Multivariable-adjusted hazard ratios for all-cause mortality in participants adhering to all 5 healthy lifestyle factors, compared with those adhering to none, were 0.37 (95% CI 0.27-0.49). We found significant increases in life expectancy for nonsmokers (2.31 years; 95% CI 0.04-5.13; P=.03), those with sufficient physical activity (1.85 years; 95% CI 0.25-4.34; P=.02), and those with adequate fruit and vegetable intake (3.25 years; 95% CI 1.29-6.81; P=.01). In addition, nonsmokers experienced a significant reduction in annual health care expenditure (-9.78%; 95% CI -46.53% to -1.45%; P=.03), as did individuals maintaining optimal body weight (-18.36%; 95% CI -29.66% to -8.57%; P=.01). Overall, participants adhering to all 5 healthy lifestyle behaviors exhibited a life gain of 7.13 years (95% CI 1.33-11.11; P=.02) compared with those adhering to one or none, with a life expectancy of 29.19 years (95% CI 25.45-33.62). Furthermore, individuals adopting all 5 healthy lifestyle factors experienced an average annual health care expenditure reduction of 28.12% (95% CI 4.43%-57.61%; P=.02) compared with those adopting one or none. CONCLUSIONS: Adopting a healthy lifestyle is associated with a longer life expectancy and a reduction of health care expenditure in Taiwanese adults. This contributes to a more comprehensive understanding of the impact of healthy lifestyle factors on the overall health and economic burden.

On the use of the healthy lifestyle index to investigate specific disease outcomes.

The healthy lifestyle index (HLI), defined as the unweighted sum of individual lifestyle components, was used to investigate the combined role of lifestyle factors on health-related outcomes. We introduced weighted outcome-specific versions of the HLI, where individual lifestyle components were weighted according to their associations with disease outcomes. Within the European Prospective Investigation into Cancer and Nutrition (EPIC), we examined the association between the standard and the outcome-specific HLIs and the risk of T2D, CVD, cancer, and all-cause premature mortality. Estimates of the hazard ratios (HRs), the Harrell's C-index and the population attributable fractions (PAFs) were compared. For T2D, the HR for 1-SD increase of the standard and T2D-specific HLI were 0.66 (95% CI: 0.64, 0.67) and 0.43 (0.42, 0.44), respectively, and the C-index were 0.63 (0.62, 0.64) and 0.72 (0.72, 0.73). Similar, yet less pronounced differences in HR and C-index were observed for standard and outcome-specific estimates for cancer, CVD and all-cause mortality. PAF estimates for mortality before age 80 were 57% (55%, 58%) and 33% (32%, 34%) for standard and mortality-specific HLI, respectively. The use of outcome-specific HLI could improve the assessment of the role of lifestyle factors on disease outcomes, thus enhancing the definition of public health recommendations.

Association of a healthy lifestyle with ambulatory 24-hour blood pressure among Chinese youths: a cross-sectional study.

BACKGROUND: This study aims to explore the association between a healthy lifestyle and abnormal ambulatory blood pressure (ABP) in Chinese youths. METHODS: A school-based sample of 1,296 college students was investigated. A lifestyle score was calculated by synthesizing five lifestyle factors, including smoking, alcohol consumption, diet, physical activity, and sleeping. The total score ranged from 0 to 5, with a higher score indicating a healthier lifestyle. This score was then divided into three categories representing low adherence to a healthy lifestyle (0-2), medium adherence (3), and high adherence (4-5). Abnormal 24-hour blood pressure (BP) was defined as systolic BP (SBP) ≥ 130 mmHg and/or diastolic BP (DBP) ≥ 80 mmHg. Abnormal daytime BP was determined as daytime SBP ≥ 135 mmHg and/or DBP ≥ 85 mmHg, while abnormal nighttime BP was characterized as nighttime SBP ≥ 120 mmHg and/or DBP ≥ 70 mmHg. We assessed the associations using the binomial regression model. RESULTS: Mean age was 18.81 years, and 74.5% were women. The prevalence of abnormal 24-hour BP, daytime BP, and nighttime BP are 4.2%, 3.7%, and 9.0%, respectively. We found that participants with high level of adherence to a healthy lifestyle had a significantly lower prevalence of abnormal 24-hour BP [prevalence ratios (PR) = 0.15, 95% CI: 0.05, 0.48] and abnormal daytime BP (PR = 0.16, 95%CI: 0.05, 0.52), when compared to those with low level of adherence and after adjusting for the potential covariates. CONCLUSIONS: A healthier lifestyle is associated with better ambulatory BP profile among youths.

[Physical methods of correction of arterial hypertension: modern concepts. (A literature review)]. / Fizicheskie metody korrektsii arterial'noi gipertenzii: sovremennye predstavleniya. (Obzor literatury).

Arterial hypertension is a major risk factor for cardiovascular disease, affecting a large proportion of the population worldwide. The study of the listed literature made it possible to assess the effectiveness and necessity of physical exercise in the treatment of hypertension syndrome, including various types of exercise, intensity, duration, and frequency, since drug treatment is not enough for successful therapy. To prevent and treat hypertension, a comprehensive approach is required, including aerobic exercise, which will lower blood pressure by dilating blood vessels.

Healthy lifestyle and prostate cancer risk in the Million Veteran Program.

BACKGROUND: This study aims to assess the impact of healthy lifestyle on prostate cancer (PCa) risk in a diverse population. METHODS: Data for 281,923 men from the Million Veteran Program (MVP), a nationwide, health system-based cohort study, were analyzed. Self-reported information at enrollment included smoking status, exercise, diet, family history of PCa, and race/ethnicity. Body mass index (BMI) was obtained from clinical records. Genetic risk was assessed via a validated polygenic score. Cox proportional hazards models were used to assess associations with PCa outcomes. RESULTS: After accounting for ancestry, family history, and genetic risk, smoking was associated with an increased risk of metastatic PCa (hazard ratio [HR], 1.83; 95% confidence interval [CI], 1.64-2.02; p < 10-16) and fatal PCa (HR, 2.73; 95% CI, 2.36-3.25; p < 10-16). Exercise was associated with a reduced risk of fatal PCa (HR, 0.86; 95% CI, 0.76-0.98; p = .03). Higher BMI was associated with a slightly reduced risk of fatal PCa, and diet score was not independently associated with any end point. Association with exercise was strongest among those who had nonmetastatic PCa at MVP enrollment. Absolute reductions in the risk of fatal PCa via lifestyle factors were greatest among men of African ancestry (1.7% for nonsmokers vs. 6.1% for smokers) or high genetic risk (1.4% for nonsmokers vs. 4.3% for smokers). CONCLUSIONS: Healthy lifestyle is minimally related to the overall risk of developing PCa but is associated with a substantially reduced risk of dying from PCa. In multivariable analyses, both exercise and not smoking remain independently associated with reduced metastatic and fatal PCa.

Association between essential metals, adherence to healthy lifestyle behavior, and ankle-brachial index.

BACKGROUND: Ankle-brachial index (ABI) is a noninvasive diagnostic method for peripheral arterial disease (PAD) and a predictor of cardiovascular events. OBJECTIVE: The present study aimed to evaluate the association between individual or combined essential metals and ABI, as well as assess the collective impact of essential metals when coupled with healthy lifestyle on ABI. METHODS: A total of 2865 participants were recruited in Wuhan Tongji Hospital between August 2018 and March 2019. Concentrations of essential metals in urine were measured by inductively coupled plasma mass spectrometer. RESULTS: The results of general linear regression models demonstrated that after adjusting for confounding factors, there was a positive association between ABI increase and per unit increase of log 10-transformed, creatinine-corrected urinary Cr (ß (95 % CI): 0.010 (0.004, 0.016), PFDR = 0.007), Fe (ß (95 % CI): 0.010 (0.003, 0.017), PFDR = 0.018), and Co (ß (95 % CI): 0.013 (0.005, 0.021), PFDR = 0.007). The WQS regression revealed a positive relationship between the mixture of essential metals and ABI (ß (95 % CI): 0.006 (0.003, 0.010), P < 0.001), with Cr and Co contributing most to the relationship (weighted 45.48 % and 40.14 %, respectively). Compared to individuals with unfavorable lifestyle and the lowest quartile of Cr, Fe and Co, those with favorable lifestyle and the highest quartile of Cr, Fe and Co exhibited the most increase in ABI (ß (95 % CI): 0.030 (0.017, 0.044) for Cr, ß (95 % CI): 0.027 (0.013, 0.040) for Fe, and ß (95 % CI): 0.030 (0.016, 0.044) for Co). CONCLUSION: In summary, our study indicates that adequate essential metal intake together with healthy lifestyle behaviors perform crucial roles in PAD protection.

The impact of COVID-19 lockdown on physical activity and sedentary behaviour in secondary school teachers: a prospective cohort study.

BACKGROUND: Mid-March 2020, Belgium went in lockdown to combat the COVID-19-pandemic. Having to provide school-based day care and adapt to online teaching, while all social, cultural and sports events and activities were cancelled, secondary school teachers' physical activity (PA) and sedentary behaviour (SB) may have been affected considerably. This study investigates the impact of the first Belgian lockdown on PA and SB in Flemish secondary school teachers. METHODS: This prospective cohort study was conducted throughout the 2019-2020 school year. PA and SB measured in March/April 2020 were compared with a pre-lockdown measurement in January/February 2020. Other pre-lockdown measurements (September/October 2019 and November/December 2019) and one other during-lockdown measurement (May/June 2020) allowed us to control for confounding. Validated questionnaires were used to assess participants' PA and SB. Generalized linear mixed models were applied in R. RESULTS: Among 624 participants (77·2% females, 43·3 ± 10·3 years), increases were observed for total PA (+ 108 min/week; p = 0·047), moderate PA (+ 217 min/week; p = 0·001), domestic and garden PA (+ 308 min/week; p < 0·0001) and leisure-time PA (+ 131 min/week; p < 0·0001), whereas work-related PA (-289 min/week; p < 0·0001) and active transportation (-38 min/week; p =0·005) decreased. No differences were observed for walking (p = 1·0) and vigorous PA (p = 0·570). Increases were found for total SB (+ 972 min/week; p < 0·0001), work-related SB (+ 662 min/week; p < 0·0001) and leisure-time SB (+ 592 min/week; p = 0·0004), whereas transport-related SB (-290 min/week; p < 0·0001) decreased. CONCLUSION: During the lockdown, we found in our sample that Flemish secondary school teachers showed an increase in SB that was 9 times as high as their PA increase. As a government, education network or school, it is crucial to sensitize, promote, and facilitate sufficient MVPA and/or walking, but likewise to discourage SB during pandemic-induced lockdowns.

Life Chances, Subjective Perceptions, and Healthy Lifestyles in Older Adults: Longitudinal Evidence From China.

OBJECTIVES: Previous studies and theories show that healthy lifestyles are affected by life chances and subjective perceptions. However, it remains unclear how older adults change between different lifestyle profiles as they age. We proposed the healthy lifestyle duality framework and tested it among older Chinese adults using a longitudinal design. METHODS: Data were obtained from 4 Chinese Longitudinal Healthy Longevity Surveys conducted between 2008 and 2018 (N = 31,445). Latent transition analysis and hierarchical multinomial growth curve models were performed to investigate healthy lifestyle profiles and their associations with life chances and subjective perceptions over time. RESULTS: Four distinct healthy lifestyle profiles were identified: healthy, risky, low-standard, and mixed groups, and their changes show path dependency. Across 10 years, the proportion of the healthy group ranged from 11.16% to 16.97%. Both life chances and subjective perceptions were longitudinally associated with healthy lifestyles, with age and cohort effects observed. DISCUSSION: Our findings support the healthy lifestyle duality framework and reveal that life chances and subjective perceptions influence lifestyle changes over time. Public health policies and health intervention programs should adapt to the specific needs of different age groups and generations.
