Leisure time and occupational physical activity, overall and cardiovascular mortality: a 24-year follow-up in the OPERA study

Background In earlier studies, the health benefits of physical activity have only been related to leisure time physical activity (LTPA). High occupational physical activity (OPA) might even be harmful. The current physical activity recommendations do not separate the OPA and LTPA. We investigated the effect of LTPA and OPA on cardiovascular morbidity and mortality during long-term follow-up. We also examined how heavy work affects the benefits of leisure time exercise. Material and methods The study was part of the OPERA study and the baseline examinations were conducted between the years 1991 and 1993. The Follow-up of events continued until the end of the year 2020. Study subjects (n = 1044) were divided into four groups according to their LTPA (“no exercise”, “irregular”, “regular” and “heavy regular”) and into three groups according to their OPA (“no activity”, “mild” and “heavy”). The amount of exercise was self-reported and the exercise status was defined at the beginning of the study. Study subjects were followed up for their overall mortality (26 years), fatal and non-fatal CVD events (24 and 20 years) and heart failure (20 years). The survival analysis was performed using Kaplan–Meier curves and Cox-proportional hazard models. Results “Heavy” OPA group subjects belonging to the “irregular” (less than 1–2 times 30 min exercise per week) LTPA group experienced the lowest overall mortality compared to other LTPA groups. Also, overall mortality was increased in the “mild” (p = 0.002) and CVD mortality in the” heavy” (p = 0.005) OPA group compared to “no activity”. The incidence of heart failure was increased in the “no exercise” LTPA compared to the “heavy regular” (p = 0.015) group. Conclusions Study subjects who were in physically demanding occupations (heavy OPA) seemed to benefit from less LTPA than WHO currently recommends. Thus we suggest targeting different LTPA recommendations to different OPA groups.

Leisure-Time Physical Activity and General Health Mitigate Effects of Job Demands on Nonrestorative Sleep: CDC National Healthy Worksite Project.

We sought to determine if leisure-time physical activity (LTPA) modified the adverse relationship between high job demands and nonrestorative sleep (NRS). We conducted a multivariate logistic regression analysis among workers from the cross-sectional National Healthy Worksite Project (n = 4683) using self-report Likert-Scale data on psychological and physical demands of jobs, LTPA and general health in relation to NRS. Not engaging in LTPA was associated with NRS for workers with jobs at the lowest or highest levels of the physical demand scale (OR 1.64, 95% CI: 0.96-2.81, OR 2.06, 95% CI: 0.95-4.45; respectively) in comparison to those who met LTPA recommendations. When assessing psychological demands, poor general health was associated with NRS at all levels of the scale independent of LTPA. LTPA may reduce NRS for workers with jobs at either extreme of physical demands.

Age-related change in peak oxygen uptake and change of cardiovascular risk factors. The HUNT Study

BackgroundLarge longitudinal studies on change in directly measured peak oxygen uptake (VO2peak) is lacking, and its significance for change of cardiovascular risk factors is uncertain. We aimed to assess ten-year change in VO2peak and the influence of leisure-time physical activity (LTPA), and the association between change in VO2peak and change in cardiovascular risk factors. Methods and resultsA healthy general population sample had their VO2peak directly measured in two (n = 1431) surveys of the Nord-Trøndelag Health Study (HUNT3; 2006–2008 and HUNT4; 2017–19).Average ten-year decline in VO2peak was non-linear and progressed from 3% in the third to about 20% in the eight decade in life and was more pronounced in men. The fit linear mixed models including an additional 2,933 observations from subjects participating only in HUNT3 showed similar age-related decline. Self-reported adherence to LTPA recommendations was associated with better maintenance of VO2peak, with intensity seemingly more important than minutes of LTPA with higher age. Adjusted linear regression analyses showed that one mL/kg/min better maintenance of VO2peak was associated with favorable changes of individual cardiovascular risk factors (all p ≤ 0.002). Using logistic regression one mL/kg/min better maintenance of VO2peak was associated with lower adjusted odds ratio of hypertension (0.95 95% CI 0.92 to 0.98), dyslipidemia (0.92 95% CI 0.89 to 0.94), and metabolic syndrome (0.86 95% CI 0.83 to 0.90) at follow-up. ConclusionsAlthough VO2peak declines progressively with age, performing LTPA and especially high-intensity LTPA is associated with less decline. Maintaining VO2peak is associated with an improved cardiovascular risk profile.

Report of Health Behavior Modification Among Latinos Diagnosed With Multiple Cardiovascular Risk Factors.

Hypertension, hypercholesterolemia, and type II diabetes are leading cardiovascular risk factors in the United States, and Latinos are disproportionately burdened by these chronic health conditions. The extent to which Latinos overall and by language spoken at home report health behavior modification following diagnosis is poorly understood. Our inclusion criteria included participants sampled in the 2011-2016 waves of the National Health and Nutrition Examination Survey who self-identified as Latinos, were 20 years of age or above, and reported a diagnosis of hypertension, hypercholesterolemia or diabetes (N=2027). We examined associations between the language spoken at home and report of adoption of 3 recommended health behaviors in the past year: weight loss, leisure-time physical activity (LTPA) and smoking cessation. Separate log-binomial models were fit to estimate prevalence ratios (PRs) for each health behavior. Approximately one third (28%) of study participants had been diagnosed with diabetes and more than half reported a diagnosis of hypercholesterolemia (65%) or hypertension (60%). Most Latinos met the highest levels of smoking cessation criteria (82%), whereas less than a third met LTPA recommendations (29%) or attempted weight loss (24%) in the past year. Fully adjusted outcome specific models showed that exclusively speaking English at home was associated with a higher probability of reporting weight loss attempt and LTPA compared with Spanish only speakers, although only LTPA was statistically significant [weight loss PR: 1.23, 95% confidence interval (CI): 0.92, 1.65; LTPA PR: 1.74; 95% CI: 1.37, 2.20; smoking cessation PR: 0.93, 95% CI: 0.86, 1.01]. Our findings provide new evidence on patterns of behavioral modification in a population-based sample of Latinos diagnosed with chronic health conditions. Findings suggest the need to promote language and culturally relevant initiatives to increase the adoption of health-enhancing behaviors and improve chronic disease management among Spanish-speaking Latinos.

Leisure-Time Physical Activity and Metabolic Syndrome in Older Adults.

Background: Metabolic syndrome (MetS) is a cluster of risk factors for cardiovascular disease, atherosclerosis and diabetes mellitus type 2 which may be reduced by practicing regular physical activity. Objective: To assess the leisure-time physical activity (LTPA) of older adults with MetS and without MetS. Methods: Cross-sectional study of older adults (55–80 years old) from Balearic Islands (Spain) with MetS (n = 333; 55% men) and without MetS (n = 144; 43.8% men). LTPA was assessed with the validated Spanish version of the Minnesota LTPA Questionnaire. Two criteria of physically active were used: >150 min/week of moderate physical activity or >75 min/week of vigorous physical activity or a combination of both, and total leisure-time energy expenditure of >300 MET·min/day. Sociodemographic and lifestyle characteristics, anthropometric variables, MetS components, and adherence to the Mediterranean diet (MD) were also measured. Results: MetS subjects showed lower energy expenditure in LTPA, lower adherence to the MD, higher obesity and waist circumference, and were less active than non-MetS peers. LTPA increased as participants got older and there was higher LTPA intensity as educational level increased. Adherence to MD was as high as LTPA was. Conclusions: MetS is associated with physical inactivity and unhealthy diet. To increase LTPA recommendations and raise awareness in the population about the health benefits of PA and high adherence to MD is highly recommended.

The Association of Prediabetes and Diabetes Risk Perception With Leisure-Time Physical Activity and Weight Loss

To examine the association of perceived risk of prediabetes and diabetes with leisure-time physical activity (LTPA) and weight loss, and determine whether the association of risk perception with LTPA and weight loss varies by race/ethnicity. Cross-sectional. National Health and Nutrition Examination Survey (NHANES) 2011-2014. Non-Latino white, non-Latino black, and Latino nondiabetic and nonprediabetic NHANES participants ≥18 years of age who were not underweight (n = 9550). Demographic characteristics, LTPA, attempted weight loss, and perceived risk of prediabetes or diabetes. Log-binomial regression models were fit to assess the association of perceived risk with meeting LTPA recommendations and having attempted to lose weight, overall and by race/ethnicity. Individuals reporting that they perceived they could be at risk for diabetes/prediabetes were less likely to meet LTPA recommendations (adjusted prevalence ratio [aPR]: 0.87; 95% confidence interval [CI]: 0.79-0.95), but significantly more likely to report attempting weight loss in the past year (aPR: 1.14; 95%CI: 1.04-1.25), compared with those reporting no risk perception. Latino and non-Latino blacks who perceived they could be at risk for diabetes/prediabetes were 25% and 35% more likely to report trying to lose weight in the past year (aPR: 1.25; 95% CI: 1.08-1.44 and aPR: 1.35; 95% CI: 1.19-1.54, respectively), compared with Latino and non-Latino blacks that did not perceive being at risk. In contrast, non-Latino whites who perceived they were at risk were 20% less likely to report meeting LTPA recommendations (aPR: 0.80; 95% CI: 0.72-0.89), compared with non-Latino whites reporting no risk perception. Findings highlight the role of perceived risk for prediabetes and diabetes in LTPA and weight loss, with findings varying by race/ethnicity. Awareness of prediabetes and diabetes risk could contribute to efforts aimed at improving LTPA and weight loss.

Health-Related Behaviors by Urban-Rural County Classification - United States, 2013.

Problem/ConditionPersons living in rural areas are recognized as a health disparity population because the prevalence of disease and rate of premature death are higher than for the overall population of the United States. Surveillance data about health-related behaviors are rarely reported by urban-rural status, which makes comparisons difficult among persons living in metropolitan and nonmetropolitan counties.Reporting Period2013.Description of SystemThe Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random-digit-dialed landline- and cellular-telephone survey of noninstitutionalized adults aged ≥18 years residing in the United States. BRFSS collects data on health-risk behaviors, chronic diseases and conditions, access to health care, and use of preventive health services related to the leading causes of death and disability. BRFSS data were analyzed for 398,208 adults aged ≥18 years to estimate the prevalence of five self-reported health-related behaviors (sufficient sleep, current nonsmoking, nondrinking or moderate drinking, maintaining normal body weight, and meeting aerobic leisure time physical activity recommendations) by urban-rural status. For this report, rural is defined as the noncore counties described in the 2013 National Center for Health Statistics Urban-Rural Classification Scheme for Counties.ResultsApproximately one third of U.S. adults practice at least four of these five behaviors. Compared with adults living in the four types of metropolitan counties (large central metropolitan, large fringe metropolitan, medium metropolitan, and small metropolitan), adults living in the two types of nonmetropolitan counties (micropolitan and noncore) did not differ in the prevalence of sufficient sleep; had higher prevalence of nondrinking or moderate drinking; and had lower prevalence of current nonsmoking, maintaining normal body weight, and meeting aerobic leisure time physical activity recommendations. The overall age-adjusted prevalence of reporting at least four of the five health-related behaviors was 30.4%. The prevalence among the estimated 13.3 million adults living in noncore counties was lower (27.0%) than among those in micropolitan counties (28.8%), small metropolitan counties (29.5%), medium metropolitan counties (30.5%), large fringe metropolitan counties (30.2%), and large metropolitan centers (31.7%).InterpretationThis is the first report of the prevalence of these five health-related behaviors for the six urban-rural categories. Nonmetropolitan counties have lower prevalence of three and clustering of at least four health-related behaviors that are associated with the leading chronic disease causes of death. Prevalence of sufficient sleep was consistently low and did not differ by urban-rural status.Public Health ActionChronic disease prevention efforts focus on improving the communities, schools, worksites, and health systems in which persons live, learn, work, and play. Evidence-based strategies to improve health-related behaviors in the population of the United States can be used to reach the Healthy People 2020 objectives for these five self-reported health-related behaviors (sufficient sleep, current nonsmoking, nondrinking or moderate drinking, maintaining normal body weight, and meeting aerobic leisure time physical activity recommendations). These findings suggest an ongoing need to increase public awareness and public education, particularly in rural counties where prevalence of these health-related behaviors is lowest.

Associations Among Leisure-Time Physical Activity, Gestational Weight Gain, and Postpartum Weight Retention With Varying Estimates of Prepregnancy Weight.

Prospective studies examining postpartum weight retention (PPWR) in relation to the appropriateness of gestational weight gain (GWG) and leisure-time physical activity (LTPA) during pregnancy and postpartum are lacking. While utilizing varying estimates of prepregnancy weight, we sought to prospectively examine associations among the aforementioned variables. Our sample consisted of a subset of women from the Archive for Research on Child Health Study (n = 68). Prepregnancy weight was obtained via questionnaire and birth certificates. GWG (2 estimates) was calculated by subtracting prepregnancy weight estimates from weight at delivery and classified as "excess" or "not excess." Pregnancy and postpartum LTPA were self-reported and dichotomized at recommended levels. Prepregnancy weight estimates were subtracted from self-reported postpartum weight to calculate 2 estimates of PPWR at 6 months. Linear regression was used to examine relationships among GWG and LTPA, and PPWR. Estimates of excess GWG were associated with increased PPWR (mean difference = 3.3-8.9 kg), even after adjustment for prepregnancy body mass index and breastfeeding. Meeting pregnancy and postpartum LTPA recommendations did not significantly predict PPWR. Our findings highlight the importance of encouraging appropriate GWG and provide insight into the impact varying estimates of prepregnancy weight may have when exploring associations among these variables.

Leisure time physical activity and long-term cardiovascular and cancer outcomes: the Busselton Health Study.

The study aimed to investigate whether meeting leisure time physical activity recommendations was associated with reduced incident and fatal cancer or cardiovascular disease (CVD) in a community-based cohort of middle- to late-aged adults with long-term follow-up. At baseline, 2,320 individuals were assessed on a large number of lifestyle and clinical parameters including their level of physical activity per week, other risk factors (e.g. smoking and alcohol use) various anthropometric measures, blood tests and medical history. Individuals were linked to hospital and mortality registry data to identify future cancer and cardiovascular events (fatal and non-fatal) out to 15 years of follow-up. Cox regression analyses adjusted for relevant confounders identified a priori were used to estimate risk for all-cause, cancer-specific and CVD-specific mortality. In the full cohort an estimated 21 % decreased risk for all-cause mortality (HR 0.79; 95 % CI 0.66-0.96) and 22 % decreased risk for fatal/non-fatal CVD events (HR 0.78; 95 % CI 0.66-0.92) was associated with baseline self-reported physical activity levels of 150 min or more. After exclusion of those with chronic co-morbidities (CVD, cancer, diabetes, chronic obstructive pulmonary disease, hypertension treatment) at baseline, lower risk for fatal/non-fatal CVD events remained significantly associated with 150 min or more of physical activity (HR 0.77; 95 % CI 0.62-0.96). Results from this well established prospective community-based cohort study support the role of leisure time physical activity in reducing all-cause mortality and CVD events (fatal/nonfatal) in the broader population studied. The data also suggest that physical activity associated reductions in risk for CVD events (fatal/nonfatal) were not overly impacted by prevalent key non-communicable diseases.

Correlates of leisure time physical activity compliance in colorectal cancer survivors

IntroductionPhysical inactivity is a risk factor for cancer morbidity and mortality, but its influence in colorectal cancer (CRC) survivors is understudied. We investigated sociodemographic, physically limiting, and behavioral predictors influencing leisure time physical activity (LTPA) among CRC survivors. MethodsPooled 1997–2010 National Health Interview Survey data (N=2378) were used to evaluate LTPA compliance in CRC survivors according to Healthy People 2010 recommendations. Univariate and multivariable logistic regression analyses were performed to identify predictors of LTPA compliance among CRC survivors. Independent variables included: age, gender, race/ethnicity, education, health insurance, body mass index (BMI), ≥2 chronic conditions limiting physical activity, time since cancer diagnosis, and poverty, marital, smoking and alcohol status. ResultsMultivariable regression models reveal that Hispanics, non-Hispanic Blacks, those with ≥2 physically limiting chronic conditions, and current smokers were less likely to comply with LTPA recommendations. CRC survivors who were of “other” race, more than one race, those with some college degree or college degree, and current drinkers were more likely to comply. DiscussionHispanics, non-Hispanic Blacks, those with >2 physically limiting chronic conditions and current smokers warrant additional efforts to encourage physical activity and to determine the impact of regular physical activity on CRC survivorship.

Racial and Ethnic Disparities in Leisure-time Physical Activity in California: Patterns and Mechanisms

Evidence has shown that racial-ethnic minorities in the U.S. are less likely than whites to engage in leisure-time physical activity (LTPA); yet few studies to date have included Asian subgroups in the analyses and mechanisms underlying these disparities are not well-known. This study uses data from the 2007 California Health Interview Survey (N=37,164) to examine racial-ethnic disparities in self-reported adherence to LTPA recommendations and explore the mediating roles of socioeconomic status (SES), acculturation, and neighborhood perceptions. Nine racial-ethnic groups were included: non-Hispanic whites, non-Hispanic blacks, Mexicans, and six largest Asian subgroups. Results confirm that racial-ethnic minorities are, in general, less likely than whites to meet LTPA recommendations, whereas heterogeneity is also evident across Asian subgroups. No significant disparity is revealed for the Japanese and Filipinos but whites are advantaged compared to all other Asian groups. Educational attainment, percent of lifetime spent in the U.S., and access to park, playground, or open space are significantly associated with meeting the LTPA recommendations. SES and acculturation play differential roles in explaining group disparities for blacks, Mexicans, and some Asian subgroups. Perceived neighborhood environment does not mediate LTPA disparities by race-ethnicity. Net of these mediators, the advantages of whites in meeting LTPA recommendations persist for blacks, Mexicans, the Chinese, and Koreans. Future research should theorize and operationalize additional multilevel pathways linking race-ethnicity and LTPA while assessing measurement errors in the existing constructs.

Changes in Leisure Time Physical Activity During Pregnancy Compared to the Prior Year

To quantify changes in leisure time physical activity (LTPA) type, frequency, duration and intensity during the first half of pregnancy as compared with the year prior to pregnancy. A cross sectional study was conducted at the Maternal University Hospital in Granada, Spain. A total of 1,175 healthy pregnant women attending a scheduled visit during the 20-22nd gestational week were enrolled in the study. Information about socio-demographic, obstetric and life-style variables during the previous year and the first half of pregnancy were collected. LTPA was quantified by assigning metabolic equivalents to each activity according to frequency, intensity and duration. The prevalence of women who met the optimal physical activity recommendations before and during pregnancy was calculated, and the McNemar-Bowker symmetry test was used to assess changes in type, frequency, intensity and duration of activities between the two periods. Some sort of LTPA was performed before and during pregnancy by 68.6% of the pregnant women. Respectively, just 27.5% and 19.4% of women fulfilled LTPA recommendations prior to pregnancy and during pregnancy; 12.6% of the women meeting recommendations prior to pregnancy later did not meet those recommendations during gestation, and 4.5% showed the reverse trend. A light increase in walking as a LTPA, and a decrease in the rest of the LTPA type activities, were seen during pregnancy. Some 13.4% of women changed from moderate--the year before- to light LTPA- during pregnancy. Pregnancy involved a decrease in LTPA, not only regarding frequency, but also duration and intensity.

The relationship between low back pain and leisure time physical activity in a working population of cleaners - a study with weekly follow-ups for 1 year

BackgroundLow back pain (LBP) and leisure time physical activity (LTPA) are considered to be closely related, and clinical guidelines for the treatment of acute LBP recommend patients stay physically active. However, the documentation for this recommendation is sparse and based on studies involving patient populations. The purpose of the study was (1) to investigate the correlation between LBP and LTPA on a weekly basis over the course of a year in a high-risk group of cleaners; and (2) to investigate if maintaining LTPA during an episode of acute LBP has a positive effect on LBP intensity in the subsequent 4 weeks.Methods188 cleaners consented to participate in a 52-week text message survey about hours of LTPA and intensity of LBP (from 0 to 9) over the previous 7 days. The correlation between LBP and LTPA was calculated by Pearson correlation coefficient. During an episode of acute LBP, a mixed effect logistic regression model was used to investigate whether cleaners who maintain LTPA have a lower pain intensity and higher probability of returning to initial pain intensity within the following four weeks compared with cleaners who decrease LTPA during acute LBP.ResultsThe correlation between weekly LTPA and LBP data was negative, but numerically low (r = -0.069) and statistically insignificant (p = 0.08). Among the 82 cleaners experiencing at least one episode of acute LBP, those maintaining LTPA during an episode of acute LBP did not have a lower pain intensity (average LBP intensity difference between groups of 0.06; 95% confidence interval (95% CI) of -0.417 to 0.539) or higher probability of returning to initial pain level (Odds ratio 1,02; 95% CI of 0.50 to 2.09) in the following four weeks compared with cleaners decreasing LTPA during acute LBP.ConclusionsHours of LTPA and intensity of LBP measured on a weekly basis throughout a year showed no close correlation. Maintaining LTPA during an episode of acute LBP did not result in a positive effect on LBP in the following 4 weeks. Documentation of LTPA recommendations for acute LBP in working populations is still needed.

Leisure-Time Physical Activity in Pregnancy and the Birth Weight Distribution: Where Is the Effect?

Leisure-time physical activity (LTPA) is recommended during pregnancy and has been associated with lower risk of delivering a large infant. We sought to characterize the effect of LTPA across the entire birth weight distribution. Women enrolled in the Pregnancy Outcomes and Community Health (POUCH) Study (1998-2004) were followed-up in 2007. Follow-up efforts were extensive for a subcohort and minimal for the remainder (nonsubcohort). Thus, 596 subcohort and 418 nonsubcohort women who delivered at term participated. Offspring were categorized as small-, appropriate-, or large-for-gestational-age (SGA, AGA, and LGA, respectively) based on gender and gestational age-specific birth weight z-scores (BWz). At follow-up, women recalled pregnancy LTPA and were classified as inactive, insufficiently active or meeting LTPA recommendations. Linear, logistic, and quantile regression analyses were conducted separately by subcohort status. Meeting LTPA recommendations decreased odds of LGA significantly among the nonsubcohort (aOR = 0.30, 95% CI: 0.14-0.64) and nonsignificantly among the subcohort (aOR = 0.68, 95% CI: 0.34-1.34). In quantile regression, meeting LTPA recommendations reduced BWz among the upper quantiles in the nonsubcohort. LTPA during pregnancy lowered odds of LGA and reduced BWz among the upper quantiles, without shifting the entire distribution. LTPA during pregnancy may be useful for reducing risks of large fetal size.

Leisure-time Physical Activity During Pregnancy And The Birth Weight Distribution: Where Is The Effect?

Previous reports have shown leisure-time physical activity (LTPA) during pregnancy to be related to small decreases in mean birth weight and/or decreased risk of giving birth to a large for gestational age infant. However, the effect of LTPA across the entire birth weight distribution has not been examined. PURPOSE: To characterize the relationship between pregnancy LTPA and birth weight. METHODS: Women enrolled in the Pregnancy Outcomes and Community Health Study (1998-2004) were followed-up in 2007. Follow-up efforts were extensive for a subcohort and minimal for the remainder, or non-subcohort. As a result, 596 (67% of eligible) subcohort and 418 (26% of eligible) non-subcohort women who delivered at term were included in this investigation. Original data collection provided maternal demographics. Medical records provided child gender, gestational age, and birth weight. Gender and gestational age-specific birth weight z-scores (BWz) were calculated and offspring were categorized as small-, appropriate-, or large-for-gestational-age (SGA, AGA, and LGA, respectively). At follow-up, women recalled pregnancy LTPA and were classified as inactive, insufficiently active (> 0 but < 7.5 kcal/kg/wk), and meeting LTPA recommendations (≥ 7.5 kcal/kg/wk). Linear, logistic, and quantile regression analyses were conducted separately by subcohort status. RESULTS: The subcohort had greater racial and socioeconomic diversity than the non-subcohort. In multivariate linear regressions, LTPA was not associated with changes in mean birth weight among either group. Among the non-subcohort, meeting LTPA recommendations significantly decreased odds of LGA (aOR=0.30, 95%CI: 0.14-0.64) without affecting odds of SGA. Quantile regression analyses showed that meeting LTPA recommendations was unrelated to BWz until the 0.65 quantile, after which it significantly reduced BWz among the non-subcohort. Results for the subcohort were similar but not statistically significant. CONCLUSIONS: LPTA during pregnancy appears to lower odds of LGA and reduce BWz among the upper quantiles without causing a mean shift in the entire distribution. Due to adverse maternal and child health effects associated with high birth weight, our results may indicate a substantial health benefit for LTPA during pregnancy.
