Physical Activity and Hypertension From Young Adulthood to Middle Age.

ABSTRACT:

Introduction

The optimum physical activity dose to achieve during young adulthood to prevent hypertension using the 2017 American College of Cardiology/American Heart Association guidelines remains undefined. This study aims to determine the association between level and change in physical activity through the adult life course and the onset of hypertension using these 2017 definitions.

Methods

In 2020, prospective community-based cohort data of 5,115 Coronary Artery Risk Development in Young Adults study participants were analyzed. The cohort included Black and White men and women aged 18-30 years at baseline (1985-1986) at 4 urban sites, collected through 30 years of follow-up (2015-2016). Individualized physical activity trajectories were developed for each participant using linear mixed models.

Results

Black women reported the lowest physical activity levels from young adulthood through middle age. Lower physical activity score (per 100 units) at age 18 years was associated with 4% (95% CI=1%, 7%, p=0.002) higher odds of hypertension incidence. Each additional 1-unit reduction per year in physical activity score was associated with 2% (95% CI=1%, 3%, p=0.001) higher annual odds of hypertension incidence. Meeting approximately the current minimum physical activity guideline levels at age 18 years and through follow-up was not protective of hypertension incidence; however, meeting approximately twice the current minimum physical activity guideline level at age 18 years and through follow-up was protective of hypertension incidence.

Conclusions

Moderate physical activity levels may need to exceed current minimum guidelines to prevent hypertension onset using 2017 American College of Cardiology/American Heart Association definitions.

Project description:BackgroundAlthough physical activity is generally protective of cardiovascular disease (CVD), less is known about how young adult physical activity relates to premature CVD events. The objective of this study was to determine the association between level and change in physical activity from young adulthood to middle age and incidence of premature CVD events before age 60.MethodsWe analyzed data collected across four urban sites from nine visits over 30 years of follow-up (1985-2016) from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a prospective community-based cohort study of 5115 Black and White women and men aged 18-30 years at baseline (1985-1986). Linear mixed models were used to develop individualized moderate-to-vigorous intensity self-reported physical activity trajectories per participant. Fatal and nonfatal coronary heart disease (CHD), heart failure, and stroke outcomes were analyzed separately and as a combined CVD event outcome.ResultsOverall, physical activity declined in young adults as they progressed through middle age. Lower physical activity scores (per 100 exercise units) in 18 year-olds were associated with higher odds of premature CHD (AOR 1.14, 95% CI 1.02-1.28), heart failure (AOR 1.21, 95% CI 1.05-1.38), stroke (AOR 1.20, 95% CI 1.04-1.39), and any CVD (AOR 1.15, 95% CI 1.06-1.24) events. Each additional annual 1-unit reduction in the physical activity score was associated with a higher annual odds of incident heart failure (1.07, 95% CI 1.02-1.13), stroke (1.06, 95% CI 1.00-1.13), and CVD (1.04, 95% CI 1.01-1.07) events. Meeting the minimum (AOR 0.74, 95% CI 0.0.57-0.96) and twice the minimum (AOR 0.55, 95% CI 0.34-0.91) Department of Health and Human Services physical activity guidelines through follow up was protective of premature CVD events.ConclusionsGiven recent trends in declining physical activity with age and associated premature CVD events, the transition from young adult to midlife is an important time period to promote physical activity.

Project description:ImportanceDetermining blood pressure (BP) patterns in young adulthood that are associated with cardiovascular disease (CVD) events in later life may help to identify young adults who have an increased risk for CVD.ObjectiveTo determine whether the long-term variability of BP across clinical visits and the rate of change in BP from young adulthood to midlife are associated with CVD and all-cause mortality by middle age, independently of mean BP during young adulthood and a single BP in midlife.Design, setting, and participantsThis prospective cohort study included a community-based sample of 3394 African American and white participants in the Coronary Artery Risk Development in Young Adults (CARDIA) Study, enrolled from March 1985 through June 1986. Patterns of systolic BP (SBP) were evaluated with measurements at year 0 (baseline) and 2, 5, 7, and 10 years after baseline. Visit-to-visit SBP variability was estimated as BP variability independent of the mean (VIM). Data were collected from March 1985 through August 2015 and analyzed from June through October 2019.Main outcomes and measuresCardiovascular disease and all-cause mortality experienced through August 2015 were adjudicated. The associations of each SBP pattern with CVD events and all-cause mortality were determined using Cox proportional hazards regression models.ResultsAt year 10, the mean (SD) age of the 3394 participants was 35.1 (3.6) years; 1557 (45.9%) were African American; 1892 (55.7%) were women; and 103 (3.0%) were taking antihypertensive medication. During a median follow-up of 20.0 (interquartile range, 19.4-20.2) years, 162 CVD events and 181 deaths occurred. When all BP pattern measurements were entered into the same model including a single SBP measurement at the year 10 examination, the hazard ratios for CVD events for each 1-SD increase in SBP measures were 1.25 (95% CI, 0.90-1.74) for mean SBP, 1.23 (95% CI, 1.07-1.43) for VIM SBP, and 0.99 (95% CI, 0.81-1.26) for annual change of SBP. The VIM for SBP was the only BP pattern associated with all-cause mortality (hazard ratio, 1.24; 95% CI, 1.09-1.41).Conclusions and relevanceThe results of this study suggest that the assessment of visit-to-visit SBP variability may help identify young adults at increased risk for CVD and all-cause mortality later in life.

Project description:Physical activity (PA) is recognized as a marker of health. The aim was to investigate PA differences from adolescence to young adulthood. European adolescents included in the HELENA study were invited to participate in a follow-up study, 10 years later. The present study included 141 adults (25.0 ± 1.4 years) for whom valid accelerometer data were available in adolescence and adulthood. Changes in PA by sex, weight and maternal education level were explored with interactions. Time spent in sedentary activity, light PA (LPA) and moderate PA (MPA) increased by 39.1, 59.6 and 6.6 min/day, respectively, whereas the time spent in vigorous PA (VPA) decreased by 11.3 min/day compared with adolescent VPA (p < 0.05). Increases in MPA were greater on weekends compared with weekdays, but we found a greater decrease in VPA on weekdays compared with weekends. Moderate-to-vigorous PA (MVPA) decreased significantly on weekdays (-9.6 min/day; 95%CI, -15.9 to -3.4), while it increased on weekends (8.4 min/day; 95%CI, 1.9 to 14.8). Significant heterogeneity was found across sexes for VPA and MVPA, with a stronger decrease in VPA in males compared with females and a significant decrease in MVPA (-12.5 min/day; 95%CI, -20.4 to -4.5) in males but not in females (1.9 min/day; 95%CI, -5.5 to 9.2). No significant heterogeneity was found to be linked to maternal education level or weight, irrespective of PA level. Conclusion: Our data suggest that the transition from adolescence to young adulthood is a critical period for lifestyle PA habits. A decline in VPA and an increasingly sedentary time were observed. The observed changes are worrying and may increase the risk of developing adverse health consequences later in life. What is Known: • The transition from adolescence to adulthood is marked by many life changes affecting lifestyle habits. Most studies tracking physical activity from adolescence to adulthood were done using PA questionnaires, which is a subjective method. What is New: • Our study bring first data on objective changes in PA patterns between adolescence and young adulthood, taking account of BMI, sex and maternal educational level. Our results suggest that the transition from adolescence to young adulthood is a critical period for lifestyle PA habits, especially for time spent on sedentary activities.

Project description:OBJECTIVES:We sought to examine the association of early adulthood blood pressure with cardiovascular disease (CVD) mortality, while accounting for middle-age hypertension. BACKGROUND:Elevated blood pressure in middle age is an established CVD risk factor, but evidence for association with measurements earlier in life is sparse. METHODS:The HAHS (Harvard Alumni Health Study) is a cohort study of 18,881 male university students who had their blood pressure measured at university entry (1914 to 1952; mean age 18.3 years) and who responded to a questionnaire mailed in either 1962 or 1966 (mean age 45.8 years) in which physician-diagnosed hypertension status was reported. Study members were subsequently followed for mortality until the end of 1998. RESULTS:Following adjustment for age, body mass index, smoking, and physical activity at college entry, compared with men who were normotensive according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure criteria (<120/<80 mm Hg), there was an elevated risk of coronary heart disease (CHD) mortality (1,917 deaths) in those who were pre-hypertensive (120 to 139/80 to 89 mm Hg) (hazard ratio [HR]: 1.21; 95% confidence interval [CI]: 1.07 to 1.36), stage 1 (140 to 159/90 to 99 mm Hg) (HR: 1.46; 95% CI: 1.25 to 1.70), and stage 2 hypertensive (?160/?100 mm Hg) (HR: 1.89; 95% CI: 1.46 to 2.45), incremental across categories (p(trend) < 0.001). After additionally accounting for middle-age hypertension, estimates were somewhat attenuated, but the pattern remained. Similar associations were apparent for total and CVD mortality, but not stroke mortality. CONCLUSIONS:Higher blood pressure in early adulthood was associated with elevated risk of all-cause mortality, CVD, and CHD, but not stroke, several decades later. Effects largely persisted after taking into account mediation by middle-age hypertension. Thus, the long-term benefits of blood pressure lowering in early adulthood are promising, but supporting trial data are required.
