Background: We investigated the association between 10 years of change in physical activity (PA) levels and 7-year all-cause mortality. Methods: Mexican American adults aged 67 and older (N = 803) participating in the Hispanic Established Population for the Epidemiologic Study of the Elderly (1995/1996–2012/2013) were included. All-cause mortality was our outcome. Participants were divided into 4 groups based on their difference in overall PA between 1995/1996 and 2005/2006 measured by the Physical Activity Scale for the Elderly. Participants were classified as having unchanged low PA (n = 339), decreased activity (n = 233), unchanged high activity (n = 166), and increased activity (n = 65). Change in the frequency of PA domains was also investigated. PA domains included leisure, household, sedentary, and walking activities. Results:After controlling for all covariates, results from the Cox proportional hazards regression found a 43% lower mortality risk in the increased PA group (hazards ratio = 0.57; 95% confidence interval, 0.34–0.97) compared with the unchanged low PA group. In the entire sample, a significantly lower mortality risk was also present among walking (hazards ratio = 0.88) and household (hazards ratio = 0.88) activities. Conclusion:Our results suggest that, independent of other factors, increasing PA is most protective of mortality among older Mexican Americans.

Abstract Background Spending more time active (and less time sedentary) is associated with many health benefits but it is unclear whether these associations differ depending on whether time spent sedentary or in moderate-vigorous physical activity (MVPA) is accumulated in long or short bouts. We used a novel analytical approach to examine whether length of sedentary and MVPA bouts associates with all-cause mortality. Methods We used data on 79,507 participants from UK Biobank. We derived the total time participants spent in activity categories (sleep, sedentary, light activity and MVPA) and in sedentary and MVPA bouts of short (1-15 minutes), medium (16-40 minutes) and long (41+ minutes) duration, on average per day. We used Cox proportion hazards regression to estimate the association of spending 10 minutes more average daily time in one activity or bout length category, coupled with spending 10 minutes less time in another, with all-cause mortality. Results Those spending more time in MVPA had lower mortality risk, irrespective of whether this replaced time spent sleeping, sedentary or in light activity. We found little evidence to suggest that mortality risk differed depending on the length of sedentary or MVPA bouts. Conclusions We uniquely show that higher total MVPA improves health irrespective of whether it is obtained from several short bouts or fewer longer bouts, supporting recent policy changes in some countries. Key messages Our results suggest that time spent in MVPA associates with lower mortality risk irrespective of whether it is obtained from several short bouts or fewer longer bouts.

Background:Associations of physical activity with all-cause mortality seem to be quite strong, but little is known about potential effect modifiers as sex, race/ethnicity, age, and obesity.Methods:Data of the Third National Health and Nutrition Examination Survey (NHANES III), conducted 1988−1994 with mortality follow-up until 2006, were used to compare mortality risk between different levels of leisure-time physical activity (LTPA) and occupational physical activity (OPA). Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs).Results:LTPA (n = 15,307) was inversely associated with all-cause mortality (HR 0.75, 95% CI 0.64−0.88 for regular vs. no LTPA). There was a statistically significant interaction with age (P = .03), with participants over 60 years of age benefitting more from regular or irregular LTPA. OPA was positively associated with all-cause mortality (HR 1.25, 95% CI 0.85−1.84 for high vs. low OPA), particularly among Mexican-Americans (HR 2.28, 95% CI 1.23−4.22); statistically significant interactions were observed for obesity and gender.Conclusions:LTPA clearly predicts all-cause mortality. However, associations between OPA and all-cause mortality are unclear and need further research with special regard to ethnic differences.

Abstract Having more years of education is independently associated with lower mortality, but it is unclear whether other attributes of schooling matter. We examined the association of high school quality and all-cause mortality across race/ethnicity. In 1960, about 5% of US high schools participated in Project Talent (PT), which collected information about students and their schools. Over 21,000 PT respondents were followed for mortality into their eighth decade of life using the National Death Index. A school quality factor, capturing term length, class size, and teacher qualifications, was used as the main predictor. First, we estimated overall and sex-stratified Cox proportional hazards models with standard errors clustered at the school level, adjusting for age, sex, composite measure of parental socioeconomic status, and 1960 cognitive ability. Second, we added an interaction between school quality and race/ethnicity. Among this diverse cohort (60% non-Hispanic Whites, 23% non-Hispanic Blacks, 7% Hispanics, 10% classified as another race/s) there were 3,476 deaths (16.5%). School quality was highest for Hispanic respondents and lowest for non-Hispanic Blacks. Non-Hispanic Blacks also had the highest mortality risk. In the whole sample, school quality was not associated with mortality risk. However, higher school quality was associated with lower mortality among those classified as another race/s (HR 0.75, 95% CI: 0.56-0.99). For non-Hispanic Blacks and Whites, the HR point estimates were unreliable, but suggest that higher school quality is associated with increased mortality. Future work will disentangle these differences in association of school quality across race/ethnicity and examine cause-specific mortality.

The Impact

Background Spending more time active (and less time sedentary) is associated with many health benefits such as improved cardiovascular health and lower risk of all-cause mortality. However, it is unclear whether these associations differ depending on whether time spent sedentary or in moderate-vigorous physical activity (MVPA) is accumulated in long or short bouts. In this study we used a novel analytical approach, that accounts for substitution (i.e. more time in MVPA means spending less time sleeping, in light activity or being sedentary), to examine whether length of sedentary and MVPA bouts associates with all-cause mortality. Methods and findings We used data on 79,507 participants from UK Biobank. We derived the total time participants spent in activity categories - sleep, sedentary, light activity and MVPA - on average per day. We also derived the time spent in sedentary and MVPA bouts of short (1-15 minutes), medium (16-40 minutes) and long (41+ minutes) duration. We used Cox proportion hazards regression to estimate the association of spending 10 minutes more average daily time in one activity or bout length category, coupled with spending 10 minutes less time in another, with all-cause mortality. Those spending more time sedentary had higher mortality risk if this replaced time spent in light activity (hazard ratio 1.02 [95% confidence interval (CI): 1.01, 1.03]), and an even higher risk if this replaced time spent in MVPA (hazard ratio 1.08 [95% CI: 1.06, 1.10]). Those spending more time in MVPA had lower mortality risk, irrespective of whether this replaced time spent sleeping, sedentary or in light activity. We found little evidence to suggest that mortality risk differed depending on the length of sedentary or MVPA bouts. A limitation of our study is that we cannot assume that these results are causal, though we adjusted for key confounders. Conclusions Using our novel analytical approach, we uniquely show that time spent in MVPA is associated with reduced mortality, irrespective of whether it replaces time spent sleeping, sedentary or in light activity. This emphasizes the specific importance of MVPA. We found little evidence to suggest that the impact of MVPA differs depending on whether it is obtained from several short bouts or fewer longer bouts, supporting recent policy changes in some countries. Further studies are needed to investigate causality and explore health outcomes beyond mortality.

Tv Watching

Purpose Physical inactivity has been associated with higher mortality risk among survivors of colorectal cancer (CRC), but the independent effects of pre- versus postdiagnosis activity are unclear, and the association between watching television (TV) and mortality in survivors of CRC is previously undefined. Methods We analyzed the associations between prediagnosis (n = 3,797) and postdiagnosis (n = 1,759) leisure time physical activity (LTPA) and TV watching and overall and disease-specific mortality among patients with CRC. We used Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% CIs, adjusting for known mortality risk factors. Results Comparing survivors of CRC reporting more than 7 hours per week (h/wk) of prediagnosis LTPA with those reporting no LTPA, we found a 20% lower risk of all-cause mortality (HR, 0.80; 95% CI, 0.68 to 0.95; P for trend = .021). Postdiagnosis LTPA of ≥ 7 h/wk, compared with none, was associated with a 31% lower all-cause mortality risk (HR, 0.69; 95% CI, 0.49 to 0.98; P for trend = .006), independent of prediagnosis activity. Compared with 0 to 2 TV hours per day (h/d) before diagnosis, those reporting ≥ 5 h/d of TV before diagnosis had a 22% increased all-cause mortality risk (HR, 1.22; 95% CI, 1.06 to 1.41; P trend = .002), and more postdiagnosis TV watching was associated with a nonsignificant 25% increase in all-cause mortality risk (HR, 1.25; 95% CI, 0.93 to 1.67; P for trend = .126). Conclusion LTPA was inversely associated with all-cause mortality, whereas more TV watching was associated with increased mortality risk. For both LTPA and TV watching, postdiagnosis measures independently explained the association with mortality. Clinicians should promote both minimizing TV time and increasing physical activity for longevity among survivors of CRC, regardless of previous behaviors.

Introduction: Habitual physical activity (PA) and less sedentary behavior have been associated with a lower risk of mortality in middle-aged adults. However, little is known about the associations of objectively-assessed PA of varying levels and sedentary time with mortality in community-dwelling older adults. Hypothesis: We hypothesized that higher overall PA and less sedentary time will be associated with a lower risk of all-cause mortality in older adults. Methods: We evaluated 1,262 Framingham Offspring Study participants (mean age 69 yrs, 54% women) with accelerometry-derived PA data (wear time ≥10 hours/day for at least 4 days using an Actical device) at their ninth examination (2011-2014). Multivariable Cox proportional hazards regression models were used to relate PA and sedentary time (separate model for each) with all-cause mortality adjusting for potential confounders. In sensitivity analysis to mitigate the potential impact of frailty on the associations evaluated, we excluded those with frailty at baseline. Results: Overall, 67 participants died during a median follow-up of 4.8 years (25 th -75 th percentiles: 4.3 - 5.3 [years]). Higher total PA, light intensity PA (LIPA), adherence to PA guidelines, and lower sedentary time were associated with a lower risk of all-cause mortality ( Table ). The results remained statistically significant even after excluding those with frailty. Higher LIPA and lower sedentary time were associated with a lower risk of all-cause mortality regardless of MVPA in both models including all participants and excluding those with frailty. Conclusions: In our investigation of a moderate-size sample of community-dwelling older adults, we confirmed that being physically active substantially lowered mortality risk. Additionally, our findings suggest that reducing sedentary time and increasing LIPA (regardless of MVPA) may be sufficient to reduce mortality risk in older adults. Additional studies of larger multi-ethnic samples of older adults are warranted to confirm our findings.

Joint Associations

Abstract Background Fruit and vegetable consumption (FVC) and leisure-time physical activity (LTPA) are associated with better health outcomes but less is known about their joint associations with the risk of mortality. We examined the joint associations of FVC and LTPA with premature mortality among midlife and ageing municipal employees, adjusting for key covariates. Methods Survey data collected in 2000–2002 among 40–60-year-old employees of the City of Helsinki, Finland, were linked with complete register data on mortality from Statistics Finland (4961 women, 1373 men; response rate 67%; written consent for register linkages 74%). FVC was dichotomised into daily or non-daily, and LTPA into high (>14 MET-hours/week including vigorous exercise) or low. Covariates included age, sex, marital status, socioeconomic position, binge drinking, smoking and self-rated health. Cox regression models were fitted. The follow-up continued until the event of death or the end of 2015. Results A total of 281 deaths occurred during the follow-up. The mortality rate was 7.1% in men and 3.7% in women. A gender interaction was found, showing differing associations for women and men. Men with both daily FVC and high LTPA had the lowest mortality risk (HR 0.19, 95% CI 0.06-0.63) after adjusting for covariates. Men with high LTPA and non-daily FVC also had a lower mortality risk (HR 0.51, 95% CI 0.29-0.90) compared to those with non-daily FVC and low LTPA. Women with daily FVC and high LTPA had a lower mortality risk initially, but after adjusting for covariates no statistically significant associations were observed. Conclusions The joint associations of FVC and LTPA with premature mortality differed between women and men. This could be related to gender differences in e.g. the causes of death, and further studies are needed to clarify this. Increasing FVC and LTPA might prevent premature mortality among men. Key messages Fruit and vegetable consumption jointly with physical activity decreased the risk of premature mortality among men only. Further studies are needed to clarify the gender difference which could be related to for example death causes.

Lower Mortality Risk

Controversy exists over the use of brief Big Five scales in health studies. We investigated links between an ultra-brief measure, the Big Five Inventory-10, and mortality in the General Social Survey. The Agreeableness scale was associated with elevated mortality risk (hazard ratio = 1.26, p = .017). This effect was attributable to the reversed-scored item “Tends to find fault with others,” so that greater fault-finding predicted lower mortality risk. The Conscientiousness scale approached meta-analytic estimates, which were not precise enough for significance. Those seeking Big Five measurement in health studies should be aware that the Big Five Inventory-10 may yield unusual results.

The authors sought to examine how much sedentary time needs to be replaced by light or moderate–vigorous physical activity in order to reduce frailty and protect against mortality. The authors built isotemporal substitution models to assess the theoretical effect of replacing sedentary behavior with an equal amount of light or moderate–vigorous activity on frailty and mortality in community-based adults aged 50 years and older. Controlling for age, sex, body mass index, marital status, race, education, employment status, and National Health and Nutrition Examination Study cycle, replacing 1 hr of sedentary time with moderate–vigorous or light physical activity daily was associated with a lower frailty index. For mortality, results varied based on frailty level. Replacing sedentary behavior with moderate–vigorous exercise was associated with lower mortality risk in vulnerable individuals; however, replacing sedentary behavior with light activity was associated with lower mortality risk in frailer individuals.

We investigated the relationship between physical activity and physical function on the risk of falls over time in a cohort of Mexican-American adults aged 75 and older from the Hispanic Established Population for the Epidemiologic Study of the Elderly (H-EPESE). Participants were divided into four groups according to their level of physical activity and physical function: low physical activity and low physical function (n = 453); low physical activity and high physical function (n = 54); high physical activity and low physical function (n = 307); and high physical activity and high physical function (n = 197). Using generalized linear equation estimation, we showed that participants with high physical activity and low physical function had a greater fall risk over time, followed by the high physical activity and high physical function group. Participants seldom took part in activities that improve physical function. To prevent falls, modifications to physical activity should be made for older Mexican Americans.
