Abstract
OBJECTIVE To explore the association of wearable device-measured moderate-to-vigorous intensity physical activity (MVPA) with cardiovascular disease (CVD) risk in long-term cancer survivors. METHODS This retrospective analysis involved a prospective cohort of 6109 cancer survivors without CVD from the UK Biobank accelerometry subsample. The MVPA volume is categorised into four groups based on guideline recommendations (0-75 min/week, 75-150 min/week, 150-300 min/week, ≥300 min/week). Cox proportional hazard models are used to investigate the association of MVPA with incident CVD. RESULTS Over a median follow-up of 7.88 years, there were 539 incident CVD events (361 incident coronary artery disease (CAD) events, 155 incident heart failure (HF) events, and 109 incident stroke events). Adjusted CVD incidence rates (95% CIs) across MVPA groups (0-75 min/week, 75-150 min/week, 150-300 min/week, ≥300 min/week) were 15.30 (12.90, 18.10), 13.50 (11.00, 16.40), 12.00 (10.20, 14.10) and 9.86 (8.35, 11.60) per 1000 person-years, respectively. Adjusted HRs (95% CI) for CVD, CAD, HF and stroke in the highest MVPA group (≥300 min/week) compared with those in the lowest MVPA group (0-75 min/week) were 0.63 (0.49, 0.80), 0.68 (0.51, 0.91), 0.66 (0.42,1.06) and 0.72 (0.42, 1.23), respectively. For obesity-related cancers, the beneficial effect on CVD was observed when exceeding 300 MVPA min/week (HR 0.54 (0.37-0.81)) compared with the lowest MVPA group. CONCLUSIONS Findings from the UK Biobank study suggest that longer MVPA durations are associated with reduced CVD risk in cancer survivors, underscoring the potential for physical activity to serve as a key component in cardio-oncology care.

Abstract
PURPOSE Identifying and managing risk factors for lower urinary tract symptoms (LUTS) is crucial because it impacts the quality of life of elderly individuals. Lifestyle factors, including physical activity (PA), and their relationship with LUTS have not been well studied. This objective of this study was to investigate the association between PA and LUTS. MATERIALS AND METHODS A total of 7,296 men were included in this cross-sectional study. PA was quantified in metabolic equivalent (MET)-hours per week, and LUTS severity was assessed using the international prostate symptom score. Logistic regression was used to analyze the association between PA and LUTS, including voiding and storage symptoms. RESULTS The average age of the participants was 57.8 years, and the prevalence of LUTS was 41.3%. After adjusting for potential confounders, PA was inversely associated with the prevalence and severity of moderate-to-severe LUTS, showing a dose-response pattern (all p for trend <0.01). Compared to the minimal activity group, which engaged in <5 MET-hours per week of PA, the odds ratios for moderate to severe LUTS were 0.83 (95% confidence interval [CI]: 0.72-0.97) for men engaging in 15-30 MET-hours per week, 0.82 (95% CI: 0.71-0.95) for 30-60 MET-hours per week, and 0.72 (95% CI: 0.62-0.84) for ≥60 MET-hours per week. The possible protective effect of PA was still observed in the additional analysis for voiding and storage symptoms showing the same dose-response pattern (all p for trend <0.01). CONCLUSIONS A higher PA level was associated with a lower prevalence and severity of total, voiding, and storage LUTS in a dose-dependent manner in Korean men.

A validated estimate of visceral adipose tissue volume in relation to cancer risk. J Natl Cancer Inst 2024; 116:1942-1951. [PMID: 39150790 PMCID: PMC12116289 DOI: 10.1093/jnci/djae193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 07/17/2024] [Accepted: 08/12/2024] [Indexed: 08/18/2024] Open
Abstract
BACKGROUND Despite the recognized role of visceral adipose tissue in carcinogenesis, its independent association with cancer risk beyond traditional obesity measures remains unknown because of limited availability of imaging data. METHODS We developed an estimation equation for visceral adipose tissue volume using elastic net regression based on demographic and anthropometric data in a subcohort of participants in the UK Biobank (UKB; n = 23 148) with abdominal magnetic resonance imaging scans. This equation was externally validated in 2713 participants from the 2017-2018 National Health and Nutrition Examination Survey according to sex, age, and race groups. We then applied the equation to the overall UKB cohort of 461 665 participants to evaluate the prospective association between estimated visceral adipose tissue and cancer risk using Cox proportional hazards models. We also calculated the population attributable risk of cancer associated with estimated visceral adipose tissue and body mass index (BMI). RESULTS Estimated visceral adipose tissue showed a high correlation with measured visceral adipose tissue in internal and external validations (r = 0.81-0.86). During a median 12-year follow-up in the UKB, we documented 37 397 incident cancer cases; estimated visceral adipose tissue was statistically significantly associated with elevated risk of obesity-related and individual cancers, independent of BMI and waist circumference. Population attributable risk for total cancer associated with high (quartiles 2-4 vs 1) estimated visceral adipose tissue (9.0% for men, 11.6% for women) was higher than high BMI (quartiles 2-4 vs 1 = 5.0% for men, 8.2% for women). CONCLUSIONS Estimated visceral adipose tissue showed robust performance in UKB and National Health and Nutrition Examination Survey and was associated with cancer risk independent of BMI and waist circumference. This study provides a potential clinical tool for visceral adipose tissue estimation and underscores that visceral adipose tissue can be an important target for cancer prevention.

Association Between Cardiorespiratory Fitness and Cancer Incidence and Cancer-Specific Mortality of Colon, Lung, and Prostate Cancer Among Swedish Men. JAMA Netw Open 2023; 6:e2321102. [PMID: 37382952 PMCID: PMC10311389 DOI: 10.1001/jamanetworkopen.2023.21102] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 05/17/2023] [Indexed: 06/30/2023] Open
Abstract
Importance Cardiorespiratory fitness (CRF) levels appear to be an important risk factor for cancer incidence and death. Objectives To examine CRF and prostate, colon, and lung cancer incidence and mortality in Swedish men, and to assess whether age moderated any associations between CRF and cancer. Design, Setting, and Participants A prospective cohort study was conducted in a population of men who completed an occupational health profile assessment between October 1982 and December 2019 in Sweden. Data analysis was performed from June 22, 2022, to May 11, 2023. Exposure Cardiorespiratory fitness was assessed as maximal oxygen consumption, estimated using a submaximal cycle ergometer test. Main Outcomes and Measures Data on prostate, colon, and lung cancer incidence and mortality were derived from national registers. Hazard ratios (HRs) and 95% CIs were calculated using Cox proportional hazards regression. Results Data on 177 709 men (age range, 18-75 years; mean [SD] age, 42 [11] years; mean [SD] body mass index, 26 [3.8]) were analyzed. During a mean (SD) follow-up time of 9.6 (5.5) years, a total of 499 incident cases of colon, 283 of lung, and 1918 of prostate cancer occurred, as well as 152 deaths due to colon cancer, 207 due to lung cancer, and 141 deaths due to prostate cancer. Higher levels of CRF (maximal oxygen consumption as milliliters per minute per kilogram) were associated with a significantly lower risk of colon (HR, 0.98, 95% CI, 0.96-0.98) and lung cancer (HR, 0.98; 95% CI, 0.96-0.99) incidence, and a higher risk of prostate cancer incidence (HR, 1.01; 95% CI, 1.00-1.01). Higher CRF was associated with a lower risk of death due to colon (HR, 0.98; 95% CI, 0.96-1.00), lung (HR, 0.97; 95% CI, 0.95-0.99), and prostate (HR, 0.95; 95% CI, 0.93-0.97) cancer. After stratification into 4 groups and in fully adjusted models, the associations remained for moderate (>35-45 mL/min/kg), 0.72 (0.53-0.96) and high (>45 mL/min/kg), 0.63 (0.41-0.98) levels of CRF, compared with very low (<25 mL/min/kg) CRF for colon cancer incidence. For prostate cancer mortality, associations remained for low (HR, 0.67; 95% CI, 0.45-1.00), moderate (HR, 0.57; 95% CI, 0.34-0.97), and high (HR, 0.29; 95% CI, 0.10-0.86) CRF. For lung cancer mortality, only high CRF (HR, 0.41; 95% CI, 0.17-0.99) was significant. Age modified the associations for lung (HR, 0.99; 95% CI, 0.99-0.99) and prostate (HR, 1.00; 95% CI, 1.00-1.00; P < .001) cancer incidence, and for death due to lung cancer (HR, 0.99; 95% CI, 0.99-0.99; P = .04). Conclusions and Relevance In this cohort of Swedish men, moderate and high CRF were associated with a lower risk of colon cancer. Low, moderate, and high CRF were associated with lower risk of death due to prostate cancer, while only high CRF was associated with lower risk of death due to lung cancer. If evidence for causality is established, interventions to improve CRF in individuals with low CRF should be prioritized.

Int J Cancer 2023. [PMID: 37129148 DOI: 10.1002/ijc.34549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 03/20/2023] [Accepted: 04/11/2023] [Indexed: 05/03/2023]
Abstract
Identifying modifiable risk factors that contribute to cancer is essential in setting up preventive strategies. Therefore, this study aimed to estimate the number and proportion of cancer cases and deaths attributable to five behavior-related risk factors-tobacco smoking, second-hand smoking, alcohol consumption, high body mass index and insufficient physical activity in Vietnam in 2020. Population attributable fractions were calculated for relationships of risk factors and cancer types based on sufficient evidence according to IARC or strong evidence according to WCRF/AICR. Relative risks were retrieved from meta-analyses where possible. Prevalence of risk factors was obtained from the most current available nationally representative population surveys in Vietnam. Cancer cases and deaths were obtained from GLOBOCAN 2020. An estimated 40.5% of all cancer cases in men (39 924 cases) and 7.8% in women (6542 cases) were attributable to these risk factors. The proportions of cancer deaths attributable to these risk factors were 44.0% in men (32 807 cases) and 8.9% in women (4235 cases). Tobacco smoking was the leading cause of cancer cases and deaths in men, followed by alcohol consumption and high BMI. In women, high BMI accounted for the highest proportion of cancer cases and second-hand smoking accounted for the highest proportion of cancer deaths. Lung and upper aerodigestive tract cancer cases and deaths could have been reduced at least by half if these risk factors had been eliminated. To reduce cancer incidence and mortality, preventive actions focusing on tobacco control are likely to have the most significant impact, especially in men.

Abstract
BACKGROUND There is little information on the feasibility and benefit of therapeutic exercise (TE) in women with metastatic breast cancer (MBC). The aim of this article is to describe the implementation of a TE intervention in MBC patients, and to determine the recruitment, compliance and improvement in outcomes after its completion. METHODS The "Therapeutic Exercise program in MBC" (TEP-MBC) consists of 1 h of individualized TE supervised by a physiotherapist in a group format, consisting of four groups of seven to eight participants. TEP-MBC was delivered twice a week, lasting 12 weeks (22 sessions), with patients considered to have completed the program when attending at least 17 sessions (>75% attendance). After referral, patients underwent a clinical interview and a physical and functional assessment. This information was complemented with patient-reported outcomes. Data about referral, compliance and assessment were collected. RESULTS Only 11 of the 30 patients completed the program. Drop-out was mainly related to personal issues and symptoms arising from the disease or treatment. All patients who completed the program improved cancer-related fatigue and increased their functional parameters. CONCLUSIONS The TEP-MBC was safe and feasible in patients with MBC, although with low compliance. The high variability in baseline measures reflects the heterogeneous level of function.

Association of Preoperative Physical Activity with Short- and Long-Term Outcomes in Patients Undergoing Palliative Resection for Metastatic Colorectal Cancer: An Inverse Probability of Treatment Weighting Analysis. Cancers (Basel) 2022; 14:cancers14030489. [PMID: 35158757 PMCID: PMC8833797 DOI: 10.3390/cancers14030489] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 01/07/2022] [Accepted: 01/15/2022] [Indexed: 12/16/2022] Open
Abstract
Simple Summary Physical activity is linked to the risk and the prognosis of colorectal cancer. However, the impact of preoperative physical activity on postoperative short-term and long-term outcomes is limited. The aim of our study was to elucidate the relationship of preoperative physical activity and postoperative outcomes in metastatic colorectal cancer patients who underwent palliative resection. After the inverse probability of the treatment weighting process, the metabolic equivalent of task < 12 group had a higher postoperative morbidity rate and mortality rate. No significant difference was found in overall survival. In patients undergoing palliative resection for metastatic colorectal cancer, preoperative leisure-time physical activity with the metabolic equivalent of task ≥ 12 was associated with reduced short-term postoperative morbidity and mortality; however, no difference was detected in long-term survival. Abstract A lack of physical activity is a generally accepted risk factor for colorectal cancer. However, research on the effect of preoperative physical activity on postoperative and long-term outcomes is limited, especially in patients with stage IV colorectal cancer who underwent palliative surgery. Patients who underwent bowel resection for stage IV primary colorectal cancer between January 1995 and December 2016 were retrospectively enrolled. A total of 2185 patients were divided into two groups according to preoperative leisure-time weekly physical activity as assessed by metabolic equivalent of task (MET) values: MET < 12 (n = 1845) and MET ≥ 12 (n = 340). Inverse probability of treatment weighting (IPTW) was used to reduce imbalance and selection biases between the two groups. After the IPTW process, the MET < 12 group showed a higher postoperative morbidity rate (18.7% vs. 10.6%; p < 0.001) and mortality rate (2.4% vs. 0.6%; p < 0.001) than the MET ≥ 12 group. No significant difference was found in overall survival. Weekly preoperative leisure-time physical activity with MET ≥ 12 was associated with reduced short-term postoperative morbidity and mortality in patients undergoing palliative resection for metastatic colorectal cancer. However, no difference was detected in long-term survival.

Abstract
Background Physical activity is associated with lower risk for endometrial cancer, but the extent to which the association is mediated by body mass index (BMI) in midlife is unclear. This study describes the physical activity-endometrial cancer association and whether BMI mediates this relationship. Methods Participants were 67 705 women in the National Institutes of Health-AARP Diet and Health Study (50-71 years) who recalled their physical activity patterns starting at age 15-18 years. We identified 5 long-term physical activity patterns between adolescence and cohort entry (ie, inactive, maintained low, maintained high, increasers, decreasers). We used Cox regression to assess the relationship between these patterns and midlife BMI and endometrial cancer, adjusting for covariates. Mediation analysis was used to estimate the proportion of the physical activity-endometrial cancer association that was mediated by midlife BMI. Results During an average 12.4 years of follow-up 1468 endometrial cancers occurred. Compared with long-term inactive women, women who maintained high or increased activity levels had a 19% to 26% lower risk for endometrial cancer (maintained high activity: hazard ratio = 0.81, 95% confidence interval [CI] = 0.67 to 0.98; increasers: hazard ratio = 0.74, 95% CI = 0.61 to 0.91). They also had a 50% to 77% lower risk for obesity in midlife (eg, maintained high activity: odds ratio for a BMI of 30-39.9 kg/m2 = 0.50, 95% CI = 0.46 to 0.55; and maintained high activity, odds ratio for a BMI of ≥40 kg/m2 = 0.32, 95% CI = 0.26 to 0.39). BMI was a statistically significant mediator accounting for 55.5% to 62.7% of the physical activity-endometrial cancer associations observed. Conclusions Both maintaining physical activity throughout adulthood and adopting activity later in adulthood can play a role in preventing obesity and lowering the risk for endometrial cancer.

Muscle-strengthening activities and cancer incidence and mortality: a systematic review and meta-analysis of observational studies. Int J Behav Nutr Phys Act 2021; 18:69. [PMID: 34051796 PMCID: PMC8164763 DOI: 10.1186/s12966-021-01142-7] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Accepted: 05/20/2021] [Indexed: 02/06/2023] Open
Abstract
Background Physical activity has been associated with reduced risk of seven types of cancer. It remains unclear, however, whether muscle-strengthening activities also reduce cancer incidence and mortality. Methods PubMed, Embase, Web of Science and Scopus were searched from inception to March 2020. Summary hazard ratio (HR) and 95% confidence intervals (CI) were estimated using random-effects models. Results Twelve studies (11 cohorts; 1 case-control), 6 to 25 years of follow-up, including 1,297,620 participants, 32,196 cases and 31,939 deaths, met inclusion criteria. Muscle-strengthening activities were associated with a 26% lower incidence of kidney cancer (HR for high vs low levels of muscle-strengthening activities: 0.74; 95% CI 0.56 to 0.98; I2 0%; 2 studies), but not with incidence of other 12 types of cancer. Muscle-strengthening activities were associated with lower total cancer mortality: HRs for high vs low levels of muscle-strengthening activities was 0.87 (95% CI 0.73 to 1.02; I2 58%; 6 studies); and HR for ≥2 times/week vs < 2 times/week of muscle-strengthening activities was 0.81 (95% CI 0.74 to 0.87; I2 0%; 4 studies). Regarding the weekly duration of muscle-strengthening activities, HR for total cancer mortality were 0.91 (95% CI 0.82 to 1.01; I2 0%; 2 studies) for 1–59 min/week and 0.98 (95% CI 0.89 to 1.07; I2 0%) for ≥60 min/week vs none. Combined muscle-strengthening and aerobic activities (vs none) were associated with a 28% lower total cancer mortality (HR 0.72; 95% CI 0.53 to 0.98; I2 85%; 3 studies). Conclusions Muscle-strengthening activities were associated with reduced incidence of kidney cancer and total cancer mortality. Combined muscle-strengthening and aerobic activities may provide a greater reduction in total cancer mortality.

[PMID: 33910983 DOI: 10.1136/oemed-2020-107253] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 04/08/2021] [Accepted: 04/11/2021] [Indexed: 02/07/2023]
Abstract
OBJECTIVES There has been no research on sedentary behaviour in the occupational domain that occupies a large portion of the daily life. METHODS We conducted a meta-analysis to investigate the association between sedentary work and colorectal cancer. We searched PubMed, Embase and Cochrane databases up to 12 August 2020 for peer-reviewed journal articles that assessed the association between sedentary work and colon or rectal cancer. Pooled estimates of ORs were obtained using random effects models. Statistical tests for publication bias, heterogeneity and sensitivity analysis were applied. RESULTS Of the 5 381 studies initially identified, 23 studies with 64 reports were eligible for inclusion. Sedentary work significantly increased the risk of colon cancer (pooled OR=1.21, 95% CI 1.11 to 1.31, p value ≤0.0001) and rectal cancer (pooled OR=1.08, 95% CI 1.00 to 1.16, p value=0.0395). The adjustment for leisure time physical activity attenuated the association and made the risk estimates non-significant for sedentary behaviour, but the association was independent of sex, control of body mass index and assessment of sedentary behaviour. CONCLUSIONS We found evidence of association between sedentary work and the risk of colon or rectal cancer. Limiting excessive sedentary work could be an important means of preventing colon and rectal cancer.

Abstract
Gastrointestinal (GI) cancers, including colorectal cancer, gastric cancer, and esophageal cancer, are a major medical and economic burden worldwide and have the largest number of new cancer cases and cancer deaths each year. Esophageal and gastric cancers are most common in developing countries, while colorectal cancer forms the major GI malignancy in Western countries. However, a great shift in the predominant GI-cancer type is happening in countries under economically transitioning and, at the same time, esophageal and gastric cancers are reigniting in Western countries due to the higher exposure to certain risk factors. The development of all GI cancers is highly associated with lifestyle habits and all can be detected by identified precancerous diseases. Thus, they are all suitable for cancer screening. Here, we review the epidemiological status of GI cancers in China, the USA, and Europe; the major risk factors and their distribution in these regions; and the current screening strategies.

Abstract
CONTEXT Excess weight has been linked to increased risks of 13 types of cancers. Physical activity is a non-nutritional modifiable lifestyle factor that is not only crucial for weight control but is also known to regulate hormones and metabolic pathways that may contribute to carcinogenesis. There is solid evidence that being physically active during middle and late adulthood lowers the risks of 3 obesity-related cancers, namely breast cancer, colon cancer, and endometrial cancer. However, the associations between physical activity at a young age (childhood, adolescence, and young adulthood; age 5 to ≤30 yr) and lifetime physical activity and the risks of breast cancer, colon cancer, and endometrial cancer are less defined. OBJECTIVE The present systematic review and meta-analysis of observational studies was performed in accordance with the MOOSE guidelines to determine whether physical activity at a young age and lifetime physical activity may lower the risks of breast cancer, colon cancer, and endometrial cancer. DATA SOURCES The PubMed and Web of Science databases were searched for relevant observational studies published from inception to July 2018. STUDY SELECTION Observational studies (prospective cohort, case-cohort, nested case-control, historical cohort, and case-control) were considered relevant if they investigated the association between physical activity at a young age or lifetime physical activity and the risks of developing selected cancers. DATA EXTRACTION A random-effects meta-analysis was performed to generate the summary relative risk (RR) with 95%CI for the highest vs the lowest category of physical activity of any type. RESULTS Eighty publications were included in the present meta-analysis. Higher physical activity at a young age was associated with lower risks of breast cancer (RR 0.81, 95%CI 0.76, 0.87) and colon cancer (RR 0.67, 95%CI 0.50, 0.88). Similarly, lifetime physical activity was inversely associated with the risks of breast cancer (RR 0.79, 95%CI 0.72, 0.86) and colon cancer (RR 0.75, 95%CI 0.69, 0.82). For breast cancer, menopausal status did not appear to modify the observed inverse association. The benefit with respect to endometrial cancer risk reduction was only observed with higher lifetime physical activity (RR 0.77, 95%CI 0.67, 0.88), not with higher physical activity at a young age (RR 0.89, 95%CI 0.73, 1.07). CONCLUSIONS Being physically active over a lifetime, starting from early childhood, may lower the risks of developing breast cancer, colon cancer, and endometrial cancer.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS), often secondary to benign prostatic hyperplasia, are a common problem for older men. Lifestyle factors, including physical activity and sedentariness, may be important LUTS risk factors and suitable targets for intervention. OBJECTIVE To determine whether physical activity and sedentariness are associated with LUTS incidence and progression. DESIGN The Health Professionals Follow-up Study is a prospective cohort of men that began in 1986. Follow-up for LUTS is complete through 2008. PARTICIPANTS Men aged 40-75 years at enrollment and members of health professions. MAIN MEASURES Total weekly metabolic equivalent of task (MET)-hour scores were calculated and were categorized (< 9, 9 to < 21, 21 to < 42, 42 to < 63, ≥ 63 MET-hours/week). Participants reported their average time/week spent sitting watching television as a measure of sedentariness, which was categorized (< 1, 1-3, 4-10, 11-29, ≥ 30 h/week). Participants completed the International Prostate Symptom Score survey and reported treatments for LUTS periodically. Cox proportional hazards regression was used to estimate multivariable-adjusted hazard ratios (HR) of physical activity and television watching with LUTS incidence and progression. KEY RESULTS After multivariable adjustment, including for body mass index (BMI), men with the highest physical activity were 19% (HR = 0.81, 95% CI = 0.74-0.89; p trend < 0.0001) less likely to develop incident moderate or worse LUTS than men in the lowest category. Men who watched television ≥ 30 h/week were 24% (HR = 1.24, 95% CI = 1.05-1.45; p trend = 0.004) more likely to develop incident moderate or worse LUTS than men who watched < 1 h/week. These associations persisted after mutual adjustment. We observed no associations with LUTS progression. CONCLUSIONS In this large prospective study, more activity and less sedentariness were associated with lower risk of incident LUTS independent of one another and BMI. Physical inactivity and sedentariness were not associated with LUTS worsening. Increasing physical activity and reducing sedentariness may be strategies for preventing LUTS in addition to their well-established benefits for other diseases.

Physical activity compared to adiposity and risk of liver-related mortality: Results from two prospective, nationwide cohorts. J Hepatol 2020; 72:1062-1069.

Abstract
BACKGROUND & AIMS Obesity in adulthood has been associated with increased risk of liver-related mortality. Whether higher levels of physical activity counteract the excess risk conferred by obesity remains unknown. We simultaneously evaluated the long-term impact of physical activity and adiposity on liver-related mortality, within 2 nationwide populations. METHODS We conducted a prospective cohort study of 77,238 women and 48,026 men, with detailed, validated assessments of weekly physical activity (metabolic equivalent task [MET]-hours]), adiposity (body mass index [BMI], waist circumference), and diet, alcohol use and clinical comorbidities, biennially from 1986 through 2012. Using Cox proportional hazards regression models, we calculated multivariable-adjusted hazard ratios (aHRs) and 95% CIs for liver-related mortality, including death from hepatocellular carcinoma (HCC) and other complications of cirrhosis. RESULTS Over 1,856,226 person-years, we recorded 295 liver-related deaths (108 HCC; 187 cirrhosis). Risk of liver-related mortality increased monotonically with higher BMI during adulthood (ptrend<0.0001) and with weight gain during early adulthood (ptrend <0.0001). The risk of liver-related mortality also declined progressively, with increasing physical activity (ptrend = 0.0003); the aHRs across increasing physical activity quintiles were: 1.0, 0.70 (95% CI 0.51-0.96), 0.59 (95% CI 0.42-0.84), 0.52 (95% CI 0.36-0.74) and 0.46 (95% CI 0.31-0.66). Compared to lean-active adults (BMI <25; ≥18 MET-hours/week), the aHRs for obese-active, lean-sedentary, and obese-sedentary adults were: 1.04 (95% CI 0.73-1.37), 2.08 (95% CI 1.21-3.33) and 3.40 (95% CI 2.06-5.56), respectively. Findings were similar for HCC-specific and cirrhosis-specific mortality. Overall, engaging in average-pace walking for >3 hours/week could have prevented 25% of liver-related deaths (95% CI 0.12-0.38). CONCLUSIONS In 2 prospective, nationwide cohorts, both excess adiposity and reduced physical activity were significant predictors of liver-related mortality. Achieving higher physical activity levels counteracted the excess liver-related risks associated with obesity. LAY SUMMARY This is the first large, prospective cohort study to simultaneously evaluate the impact of obesity and physical activity on the long-term risk of liver-related mortality in 2 nationwide populations of American men and women. The study demonstrated that obesity predicted significantly increased risk of liver-related mortality, while physical activity predicted significantly lower risk of liver-related mortality. Importantly, the excess risk of liver-related mortality observed with obesity was no longer statistically significant among adults who engaged in the equivalent of average-pace walking for 3 hours or more, per week.

Abstract
BACKGROUND Physical activity might be directly or indirectly linked to the risk of colorectal cancer and the prognosis of patients with colorectal cancer. OBJECTIVE This study aimed to elucidate whether preoperative physical activity plays a role in reducing short-term postoperative complications and improving long-term survival of patients with colorectal cancer. DESIGN This was a retrospective analysis of prospectively collected data. SETTINGS This study was conducted at a department of colorectal surgery in a tertiary teaching hospital between January 1995 and December 2016. PATIENTS Patients who underwent curative resection for stage I to III primary colorectal cancer were enrolled. According to the preoperative leisure-time weekly metabolic equivalent of task values, patients were divided into 2 groups: the metabolic equivalent of task <12 group and the metabolic equivalent of task ≥12 group. A 1:1 propensity score matching was used to reduce imbalance and selection biases based on 6 covariates, namely, age, sex, BMI, tumor location, tumor stage, and adjuvant chemotherapy administration. MAIN OUTCOME MEASURES χ tests were used to analyze short-term postoperative complications. Kaplan-Meier analyses were used to evaluate disease-free survival and overall survival. RESULTS In the matched cohort patients, significant differences in overall postoperative complications and mortality were observed in favor of the metabolic equivalent of task ≥12 group, although there was no difference in any single item of postoperative morbidity. The results of the Kaplan-Meier analysis and log-rank test demonstrated a significant survival benefit in the metabolic equivalent of task ≥12 group compared with the metabolic equivalent of task <12 group both for disease-free and overall survival. LIMITATIONS This study is limited by its retrospective nature. CONCLUSIONS This single-institute study provides evidence of the association of preoperative leisure-time physical activity with short-term postoperative morbidity and mortality, as well as long-term survival.

Abstract
Objective To examine the association between leisure-time physical activity (LTPA) and long-term cancer risk in a nationwide cohort of older adults. Participants and Methods The cohort comprised participants of a national survey conducted between July 2005 and December 2006, constituting a random sample of Israeli community-dwelling adults aged 65 years or older. Based on self-reported LTPA habits, participants were classified as sufficiently active, insufficiently active, or inactive according to published guidelines. Cancer diagnosis was assessed via the Israeli National Cancer Registry through September 2015. Inverse probability weighted hazard ratios for incident cancer, based on propensity score, were estimated for LTPA categories. Results Analysis included 1542 participants with no history of cancer at baseline (median [25th-75th percentile] age, 73 years [69-78 years]; 826 [53.6%] women). Inactive participants (n=641 [41.6%]) were more likely to be female, of lower socioeconomic status, and with higher body mass index and poorer perceived health compared with their insufficiently active (n=443 [28.7%]) and sufficiently active (n=458 [29.7%]) counterparts. In the propensity score–weighted synthetic sample, the distribution of measured baseline covariates was similar across LTPA categories. Over a median follow-up of 9 years, 254 new cancer cases (16.5%) were diagnosed. Leisure-time physical activity was inversely associated with incident cancer, with adjusted hazard ratios (95% CIs) of 0.66 (0.46-0.93) in insufficiently active and 0.59 (0.42-0.82) in sufficiently active participants compared with inactive individuals (P value for trend = .002). Conclusion Among older adults, engaging in LTPA, even at lower levels than officially recommended, may have a beneficial effect on primary prevention of cancer.

Abstract
Globally, colorectal cancer (CRC) is the third most commonly diagnosed malignancy and the second leading cause of cancer death. Arising through three major pathways, including adenoma-carcinoma sequence, serrated pathway and inflammatory pathway, CRC represents an aetiologically heterogeneous disease according to subtyping by tumour anatomical location or global molecular alterations. Genetic factors such as germline MLH1 and APC mutations have an aetiologic role, predisposing individuals to CRC. Yet, the majority of CRC is sporadic and largely attributable to the constellation of modifiable environmental risk factors characterizing westernization (for example, obesity, physical inactivity, poor diets, alcohol drinking and smoking). As such, the burden of CRC is shifting towards low-income and middle-income countries as they become westernized. Furthermore, the rising incidence of CRC at younger ages (before age 50 years) is an emerging trend. This Review provides a comprehensive summary of CRC epidemiology, with emphasis on modifiable lifestyle and nutritional factors, chemoprevention and screening. Overall, the optimal reduction of CRC incidence and mortality will require concerted efforts to reduce modifiable risk factors, to leverage chemoprevention research and to promote population-wide and targeted screening.

Abstract
BACKGROUND Physical inactivity is an established risk factor for several cancers of the digestive system and female reproductive organs, but the evidence for liver cancers is less conclusive. METHODS The aim of this study was to synthesize prospective observational studies on the association of physical activity and liver cancer risk by means of a systematic review and meta-analysis. We searched Medline, Embase, and Scopus from inception to January 2019 for prospective studies investigating the association of physical activity and liver cancer risk. We calculated mean hazard ratios (HRs) and 95% confidence intervals (CIs) using a random-effects model. We quantified the extent to which an unmeasured confounder or an unaccounted selection variable could shift the mean hazard ratio to the null. RESULTS Fourteen prospective studies, including 6,440 liver cancers, were included in the systematic review and meta-analysis. The mean hazard ratio for high compared with low physical activity was 0.75 (95% CI = 0.63 to 0.89; 95% prediction interval = 0.52 to 1.07; I² = 64.2%). We estimated that 67.6% (95% CI = 56.6% to 78.5%) of all true effect estimates would have a hazard ratio less than 0.8. Bias analysis suggested than an unobserved confounder would have to be associated with a 1.99-fold increase in the risk of physical activity or liver cancer to explain away the observed mean hazard ratio. An unaccounted for selection variable would have to be related to exposure and endpoint with a relative risk of 1.58 to explain away the mean hazard ratio. CONCLUSIONS Physical activity is inversely related to the risk of liver cancer. Further studies with objectively measured physical activity and quasi-experimental designs addressing confounding are needed.

Towards a circulating marker of hepato-visceral fat excess: S100A4 in adolescent girls with polycystic ovary syndrome - Evidence from randomized clinical trials. Pediatr Obes 2019; 14:e12500. [PMID: 30653851 DOI: 10.1111/ijpo.12500] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2018] [Revised: 11/29/2018] [Accepted: 12/03/2018] [Indexed: 12/16/2022]
Abstract
S100A4 is a marker of subcutaneous adipose tissue dysfunction. Polycystic ovary syndrome (PCOS) is often driven by hepato-visceral adiposity. PCOS phenotypes are normalized more by reduction of central fat with spironolactone/pioglitazone/metformin (SPIOMET) than by oral contraceptive (OC) treatment. We studied whether circulating S100A4 concentrations are high in adolescents with PCOS and, if so, whether they normalize more with OC or SPIOMET. Assessments included circulating S100A4, endocrine markers, body composition, abdominal fat partitioning in controls (n = 12) and girls with PCOS (n = 51; age 15.8 y; body mass index [BMI] 24.5 kg/m2 ), and 1-year changes in girls with PCOS randomized for OC (n = 27) or SPIOMET (n = 24) treatment. Mean S100A4 concentrations were 71% higher (P < 0.001) in girls with PCOS than in controls and associated with hepato-visceral adiposity (r = 0.47; P = 0.001); S100A4 concentrations decreased more (P < 0.01) with SPIOMET, those decreases associating to hepato-visceral fat loss (r = 0.50; P < 0.0001). S100A4 may become a circulating marker of hepato-visceral fat excess in adolescents with PCOS.

Abstract
BACKGROUND & AIMS To date, evidence on the association between physical activity and risk of hepatobiliary cancers has been inconclusive. We examined this association in the European Prospective Investigation into Cancer and Nutrition cohort (EPIC). METHODS We identified 275 hepatocellular carcinoma (HCC) cases, 93 intrahepatic bile duct cancers (IHBCs), and 164 non-gallbladder extrahepatic bile duct cancers (NGBCs) among 467,336 EPIC participants (median follow-up 14.9 years). We estimated cause-specific hazard ratios (HRs) for total physical activity and vigorous physical activity and performed mediation analysis and secondary analyses to assess robustness to confounding (e.g. due to hepatitis virus infection). RESULTS In the EPIC cohort, the multivariable-adjusted HR of HCC was 0.55 (95% CI 0.38-0.80) comparing active and inactive individuals. Regarding vigorous physical activity, for those reporting >2 hours/week compared to those with no vigorous activity, the HR for HCC was 0.50 (95% CI 0.33-0.76). Estimates were similar in sensitivity analyses for confounding. Total and vigorous physical activity were unrelated to IHBC and NGBC. In mediation analysis, waist circumference explained about 40% and body mass index 30% of the overall association of total physical activity and HCC. CONCLUSIONS These findings suggest an inverse association between physical activity and risk of HCC, which is potentially mediated by obesity. LAY SUMMARY In a pan-European study of 467,336 men and women, we found that physical activity is associated with a reduced risk of developing liver cancers over the next decade. This risk was independent of other liver cancer risk factors, and did not vary by age, gender, smoking status, body weight, and alcohol consumption.

Body mass index, mammographic density, and breast cancer risk by estrogen receptor subtype. Breast Cancer Res 2019; 21:48.

Abstract
Background Obesity and elevated breast density are common risk factors for breast cancer, and their effects may vary by estrogen receptor (ER) subtype. However, their joint effects on ER subtype-specific risk are unknown. Understanding this relationship could enhance risk stratification for screening and prevention. Thus, we assessed the association between breast density and ER subtype according to body mass index (BMI) and menopausal status. Methods We conducted a case-control study nested within two mammography screening cohorts, the Mayo Mammography Health Study and the San Francisco Bay Area Breast Cancer SPORE/San Francisco Mammography Registry. Our pooled analysis contained 1538 ER-positive and 285 ER-negative invasive breast cancer cases and 4720 controls matched on age, menopausal status at time of mammogram, and year of mammogram. Percent density was measured on digitized film mammograms using computer-assisted techniques. We used polytomous logistic regression to evaluate the association between percent density and ER subtype by BMI subgroup (normal/underweight, < 25 kg/m2 versus overweight/obese, ≥ 25 kg/m2). We used Wald chi-squared tests to assess for interactions between percent density and BMI. Our analysis was stratified by menopausal status and hormone therapy usage at the time of index mammogram. Results Percent density was associated with increased risk of overall breast cancer regardless of menopausal status or BMI. However, when analyzing breast cancer across ER subtype, we found a statistically significant (p = 0.008) interaction between percent density and BMI in premenopausal women only. Specifically, elevated percent density was associated with a higher risk of ER-negative than ER-positive cancer in overweight/obese premenopausal women [OR per standard deviation increment 2.17 (95% CI 1.50–3.16) vs 1.33 (95% CI 1.11–1.61) respectively, Pheterogeneity = 0.01]. In postmenopausal women, elevated percent density was associated with similar risk of ER-positive and ER-negative cancers, and no substantive differences were seen after accounting for BMI or hormone therapy usage. Conclusions The combination of overweight/obesity and elevated breast density in premenopausal women is associated with a higher risk of ER-negative compared with ER-positive cancer. Eighteen percent of premenopausal women in the USA have elevated BMI and breast density and may benefit from lifestyle modifications involving weight loss and exercise.

Abstract
The prevalence of excess body weight and the associated cancer burden have been rising over the past several decades globally. Between 1975 and 2016, the prevalence of excess body weight in adults-defined as a body mass index (BMI) ≥ 25 kg/m2 -increased from nearly 21% in men and 24% in women to approximately 40% in both sexes. Notably, the prevalence of obesity (BMI ≥ 30 kg/m2 ) quadrupled in men, from 3% to 12%, and more than doubled in women, from 7% to 16%. This change, combined with population growth, resulted in a more than 6-fold increase in the number of obese adults, from 100 to 671 million. The largest absolute increase in obesity occurred among men and boys in high-income Western countries and among women and girls in Central Asia, the Middle East, and North Africa. The simultaneous rise in excess body weight in almost all countries is thought to be driven largely by changes in the global food system, which promotes energy-dense, nutrient-poor foods, alongside reduced opportunities for physical activity. In 2012, excess body weight accounted for approximately 3.9% of all cancers (544,300 cases) with proportion varying from less than 1% in low-income countries to 7% or 8% in some high-income Western countries and in Middle Eastern and Northern African countries. The attributable burden by sex was higher for women (368,500 cases) than for men (175,800 cases). Given the pandemic proportion of excess body weight in high-income countries and the increasing prevalence in low- and middle-income countries, the global cancer burden attributable to this condition is likely to increase in the future. There is emerging consensus on opportunities for obesity control through the multisectoral coordinated implementation of core policy actions to promote an environment conducive to a healthy diet and active living. The rapid increase in both the prevalence of excess body weight and the associated cancer burden highlights the need for a rejuvenated focus on identifying, implementing, and evaluating interventions to prevent and control excess body weight.

Abstract
Background Studies have consistently found that obesity is associated with poor self-rated health, but how body mass index (BMI) developed in the lead up to poor self-rated health is unknown. Methods We nested a longitudinal case-control study in the English Longitudinal Study of Ageing (1998–2015) to investigate BMI trajectories in the years preceding a first self-report of poor health. Participants rated their health at each data collection; every other collection included a BMI assessment by a nurse. Case status was defined as a first report of poor health during follow-up. Three age- and sex-matched controls were identified per case using density sampling. BMI trajectories were fitted to time backwards prior to first report of poor health using mixed-effects models. Age and sex were potential modifiers. We conducted subgroup analyses of those not reporting certain chronic diseases or smoking. Results We identified 732 cases and 2195 controls. Age, but not sex, modified the association between BMI and self-rated health. Participants reporting poor health at age 60 had a 1.5 kg/m2 (95%CI: 0.8 to 2.1) higher BMI at the time of reporting than controls, and their BMI had previously increased markedly (1.3 kg/m2 95%CI: 0.9 to 1.8 over ten years). After age 75, cases no longer had higher BMI than controls, and their BMI had decreased sharply prior to reporting poor health (e.g. -2.0 kg/m2 95%CI: -2.6 to -1.5 per decade on average for those reporting poor health at age 90). Age was also an effect modifier among those without diabetes, however BMI trajectories were more similar among the middle-aged. The subgroup analysis of those without cardiovascular disease, cancer and chronic lung disease showed similar results to the main findings. Conclusion Development of BMI was associated with poor self-rated health; however, the nature of the association depended markedly on age.

Abstract
Several biological mechanisms linking physical activity with cancer have been proposed. However, the influence of specific components of physical activity (volume, type and intensity), and their interaction with adiposity and diet, on cancer-related biomarkers remain unclear. We used cross-sectional data on 7,219 men in the Health Professionals Follow-up Study (1992-1994) with C-reactive protein (CRP), interleukin-6 (IL6), tumor necrosis factor alpha receptor 2 (TNFαR2), adiponectin, C-peptide and triglycerides/high-density lipoprotein cholesterol ratio (TG/HDL). Details on physical activity, diet and adiposity were assessed by questionnaires. We used multivariable-adjusted linear regression analyses to estimate relative concentrations of biomarkers by physical activity. Total physical activity was favorably associated with all biomarkers in a fairly linear manner. Comparing the highest (63+ metabolic equivalent (MET)-hr/week) to the lowest (0-8.9 MET-hr/week) physical activity groups, the percent relative difference in concentration of biomarkers was -31% for CRP, -22% for IL6, -8% for TNFαR2, +9% for adiponectin, -22% for C-peptide, and -20% for TG/HDL. These differences were modestly attenuated after adjustment for adiposity. For the same total MET-hours of physical activity, the association was stronger for men engaging in both aerobic and resistance exercises compared to those engaging in aerobic only. However, no difference was found between those engaging in vigorous activities (≥20% of total MET-hours) compared to those who did smaller amount of vigorous activities. Physical activity showed similar associations for these biomarkers regardless of adiposity and dietary pattern. In conclusion, high physical activity, preferably aerobic plus resistance training, was associated with favorable cancer-related biomarkers.

Abstract
Recently, Ioannidis questioned whether nutritional epidemiology could be reconciled with good scientific principles, and suggested that the field needs radical reform. One of the reforms he advocated was more randomized trials; though what diet would be tested and how it would be measured were unspecified, how adherence would be monitored was unclear or unimportant, and the length of time vaguely stated as "lifelong". The other reform was reanalysis of shared data, which actually already exists in a large number of cohort consortia of individual pooled data. The 2018 report analysis of diet and cancer from the World Cancer Fund/American Institute of Cancer Research presents a sharply different picture of our knowledge of nutrition and cancer, which has evolved immensely in the past 3 decades. Based on current knowledge, factors related to energy balance, encompassed by body mass anthropometric measures might account for about 10-15% of the U.S. cancer burden. This 10-15% encompasses physical activity and obesogenic effects of diet. About 5% may be attributable to alcohol, and another 5% to specific dietary factors combined (e.g., red and processed meat, whole grains, fiber, calcium, fruits, and vegetables). Surrogates such as attained height and age at menarche are influenced by nutrition and are consistent risk factors for cancer, supporting the importance of early nutrition. Recent data suggest that early life dietary patterns, which may be modifiable, may be important. Though important questions remain, our understanding of nutrition and cancer over the life course is coherent and has been informed by nutritional epidemiology and other data.

Preventable fractions of colon and breast cancers by increasing physical activity in Brazil: perspectives from plausible counterfactual scenarios. Cancer Epidemiol 2018; 56:38-45. [PMID: 30032026 PMCID: PMC6562241 DOI: 10.1016/j.canep.2018.07.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2018] [Revised: 06/20/2018] [Accepted: 07/03/2018] [Indexed: 12/21/2022]
Abstract
BACKGROUND Physical activity is associated with lower risk of colon and breast cancers. Herein we estimated preventable fractions of colon and breast cancers in Brazil by increasing population-wide physical activity to different counterfactual scenarios. METHODS We used data from a representative national survey in Brazil and corresponding relative risks of colon and postmenopausal breast cancers from a meta-analysis. Estimated cancer incidence was retrieved from GLOBOCAN and Brazilian National Cancer Institute. Five counterfactual scenarios for physical activity were considered: (i) theoretical minimum risk exposure level (≥8,000 metabolic equivalent of tasks-minute/week - MET-min/week); (ii) physical activity recommendation (≥600 MET-min/week); (iii) a 10% reduction in prevalence of insufficient physical inactivity (<600 MET-min/week); (iv) physical activity level in each state equals the most active state in Brazil; (v) closing the gender differences in physical activity. RESULTS About 19% (3,630 cases) of colon cancers and 12% (6,712 cases) of postmenopausal breast cancers could be prevented by increasing physical activity to ≥8,000 MET-min/week. Plausible counterfactual scenarios suggested the following impact on cancer prevention: reaching physical activity recommendation: 1.7% (1,113 cases) of breast and 6% (1,137 cases) of colon; 10% reduction in physical inactivity prevalence: 0.2% (111 cases) of breast and 0.6% (114 cases) of colon; most active state scenario: 0.3% (168 cases) of breast and 1% (189 cases) of colon; reducing gender differences in physical activity: 1.1% (384 cases) of breast and 0.6% (122 cases) of colon. CONCLUSIONS High levels of physical activity are required to achieve a sizable impact on breast and colon cancer prevention in Brazil.
