Purpose: Socioeconomic status has been related to resting blood pressure (BP) levels at different stages of life. However, the association of childhood socioeconomic status (SES) and adulthood exercise BP is largely unknown. Therefore, we studied the association of childhood SES with adulthood maximal exercise BP., Materials and Methods: This investigation consisted of 373 individuals (53% women) participating in the Cardiovascular Risk in Young Finns Study who had data concerning family SES in childhood (baseline in 1980, at age of 6-18 years) and exercise BP response data in adulthood (follow-up in adulthood in 27-29 years since baseline). A maximal cardiopulmonary exercise test with BP measurements was performed by participants, and peak exercise BP was measured., Results: In stepwise multivariable analysis including childhood risk factors and lifestyle factors (body mass index, systolic BP, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, insulin, fruit consumption, vegetable consumption, and physical activity), lower family SES in childhood was associated with higher maximal exercise BP in adulthood (β value ± SE, 1.63 ± 0.77, p  = 0.035). The association remained significant after further adjustment with participants SES in adulthood (β value ± SE, 1.68 ± 0.65, p  = 0.011) and after further adjustment with adulthood body-mass index, systolic BP, maximal exercise capacity, and peak heart rate in exercise (β value ± SE, 1.25 ± 0.56, p  = 0.027)., Conclusions: These findings suggest that lower childhood family SES is associated with higher maximal exercise BP in adulthood.

Aims: Childhood family environment is associated with adulthood health behaviours and cardiovascular health, but limited data are available concerning the relationship between childhood family environment and adulthood haemodynamic determinants of blood pressure. We evaluated how childhood family environment predicts adulthood systemic haemodynamics., Methods: The sample came from the Cardiovascular Risk in Young Finns Study ( n =1554-1620). Childhood family environment (1980) was assessed with four cumulative risk scores: socioeconomic family risk, risky emotional family atmosphere, stressful life events, and parents' risky health behaviours. Haemodynamic outcomes in 2007 (participants being 30-45 year-olds) included stroke volume index, systemic vascular resistance index, cardiac output index and heart rate. Analyses were adjusted for childhood (1980) cardiovascular risk factors (high-density lipoprotein and low-density lipoprotein cholesterol, triglycerides, insulin, body mass index and systolic blood pressure); and adulthood (2007) health behaviours (alcohol consumption, smoking, physical activity); and finally for adulthood cardiovascular risk factors., Results: When adjusted for age and sex, high socioeconomic family risk predicted lower stroke volume index ( P =0.001), higher heart rate ( P =0.001) and higher systemic vascular resistance index ( P =0.030). These associations remained after controlling for childhood cardiovascular covariates or adulthood health behaviours ( P ⩽0.02 for all) but diluted after controlling for adulthood cardiovascular risk factors. The other childhood cumulative risk scores (stressful life events, risky emotional atmosphere, or parents' risky health behaviour) did not predict adulthood haemodynamic outcomes., Conclusions: High childhood socioeconomic family risk predicted adulthood haemodynamic outcomes independently of childhood cardiovascular risk factors and adulthood health behaviours, while other childhood psychosocial adversities were not associated with cardiovascular function in adulthood., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: Individual socioeconomic status is associated with increased arterial stiffness, but limited data are available on the relations of neighbourhood deprivation with this vascular measure. We prospectively examined whether neighbourhood deprivation in childhood and adulthood predicts arterial stiffness indicated by pulse wave velocity (PWV). Materials and methods: The study population comprised 1,761 participants aged 3-18 years at baseline (1980) from the longitudinal Cardiovascular Risk in Young Finns cohort study. PWV was measured in 2007 by whole-body impedance cardiography at ages 30-45 years. Cumulative lifetime neighbourhood deprivation was assessed using data from socioeconomic circumstances in participants' lifetime residential neighbourhoods, categorised as low versus high deprivation. Results: High deprivation in childhood and adulthood was associated with higher PWV in adulthood after adjustment for age, sex, and place of birth (mean difference = 0.57 m/s, 95%CI = 0.26-0.88, P for trend = 0.0004). This association was attenuated but remained statistically significant after further adjustment for childhood parental socioeconomic status and adulthood individual socioeconomic status (mean difference = 0.37 m/s, 95%CI = 0.05-0.70, P for trend 0.048). Also, low individual socioeconomic status in adulthood was associated with higher PWV when adjusted for age, sex, place of birth, parental socioeconomic status in childhood, and lifetime neighbourhood deprivation (mean difference = 0.54 m/s, 95%CI = 0.23-0.84, P for trend 0.0001). Conclusion: These findings suggest that lifetime neighbourhood deprivation and low adulthood socioeconomic status are independent risk factors for increased arterial stiffness in adulthood.

Purpose: There are limited data available concerning the effects of lifetime risk factors and lifestyle on systemic hemodynamics, especially on systemic vascular resistance. The purpose of the study was to evaluate how lifetime cardiovascular risk factors (body mass index (BMI), high-density lipoprotein, low-density lipoprotein, triglycerides, systolic blood pressure, blood glucose) and lifestyle factors (vegetable consumption, fruit consumption, smoking and physical activity) predict systemic vascular resistance index (SVRI) and cardiac index (CI) assessed in adulthood., Materials and Methods: Our study cohort comprised 1635 subjects of the Cardiovascular Risk in Young Finns Study followed up for 27 years since baseline (1980; aged 3-18 years, females 54.3%) who had risk factor and lifestyle data available since childhood. Systemic hemodynamics were measured in 2007 (aged 30-45 years) by whole-body impedance cardiography., Results: In the multivariable regression analysis, independent predictors of the adulthood SVRI were childhood BMI, blood glucose, vegetable consumption, smoking, and physical activity ( p  ≤ .046 for all). Vegetable consumption, smoking, and physical activity remained significant when adjusted for corresponding adult data ( p  ≤ .036 for all). For the CI, independent predictors in childhood were BMI, systolic blood pressure, vegetable consumption, and physical activity ( p  ≤ .044 for all), and the findings remained significant after adjusting for corresponding adult data ( p  ≤ .046 for all). The number of childhood and adulthood risk factors and unfavourable lifestyle factors was directly associated with the SVRI ( p  < .001) in adulthood. A reduction in the number of risk factors and unfavourable lifestyle factors or a favourable change in BMI status from childhood to adulthood was associated with a lower SVRI in adulthood ( p  < .001)., Conclusion: Childhood BMI, blood glucose, vegetable consumption, smoking and physical activity independently predict systemic vascular resistance in adulthood. A favourable change in the number of risk factors or BMI from childhood to adulthood was associated with lower vascular resistance in adulthood.

Purpose: Elevated blood pressure (BP) in childhood has been associated with increased adulthood BP. However, BP and its change from childhood to adulthood and the risk of exaggerated adulthood exercise BP response are largely unknown. Therefore, we studied the association of childhood and adulthood BP with adulthood exercise BP response., Materials and Methods: This investigation consisted of 406 individuals participating in the ongoing Cardiovascular Risk in Young Finns Study (baseline in 1980, at age of 6-18 years; follow-up in adulthood in 27-29 years since baseline). In childhood BP was classified as elevated according to the tables from the International Child Blood Pressure References Establishment Consortium, while in adulthood BP was considered elevated if systolic BP was ≥120 mmHg or diastolic BP was ≥80 mmHg or if use of antihypertensive medications was self-reported. A maximal cardiopulmonary exercise test with BP measurements was performed by participants in 2008-2009, and exercise BP was considered exaggerated (EEBP) if peak systolic blood pressure exceeded 210 mmHg in men and 190 mmHg in women., Results: Participants with consistently high BP from childhood to adulthood and individuals with normal childhood but high adulthood BP had an increased risk of EEBP response in adulthood (relative risk [95% confidence interval], 3.32 [2.05-5.40] and 3.03 [1.77-5.17], respectively) in comparison with individuals with normal BP both in childhood and adulthood. Interestingly, individuals with elevated BP in childhood but not in adulthood also had an increased risk of EEBP [relative risk [95% confidence interval], 2.17 [1.35-3.50])., Conclusions: These findings reinforce the importance of achieving and sustaining normal blood pressure from childhood through adulthood.

Purpose: To study whether systemic hemodynamics, especially systemic vascular resistance, predicts the development of hypertension and improves the risk prediction of incident hypertension beyond common risk factors in the risk models in young adults., Materials and Methods: Typical risk factors for hypertension in the risk prediction models (systolic and diastolic blood pressure, parental history of hypertension, age, sex, body-mass index, smoking), laboratory values (high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, glucose, insulin, C-reactive protein), heart rate (HR), stroke index (SI), and systemic vascular resistance index (SVRI) calculated by whole-body impedance cardiography were evaluated in 2007 and blood pressure in 2011 in 1293 Finnish adults (aged 30-45 years; females 56%; n  = 1058 normotensive in 2007)., Results: Of hemodynamic variables, SVRI and HR evaluated in 2007 were independently associated with systolic blood pressure ( p  < 0.001 and p  = 0.047, respectively) and SVRI with diastolic blood pressure measured in 2011 ( p  = 0.014), and SVRI and HR were independent predictors of incident hypertension ( p  < 0.001 and p  = 0.024, respectively). SVRI was the most significant predictor of incident hypertension independently of other risk factors (odds ratio 2.73 per 1 standard deviation increase, 95% confidence interval 1.93-3.94, p  < 0.001). The extended prediction model (including SVRI) improved the incident hypertension risk prediction beyond other risk factors, with an area under the receiver operating characteristic curve of 0.846 versus 0.817 ( p  = 0.042) and a continuous net reclassification improvement of 0.734 ( p  < 0.001)., Conclusions: These findings suggest that systemic vascular resistance index predicts the incidence of hypertension in young adults and that the evaluation of systemic hemodynamics could provide an additional tool for hypertension risk prediction.

Purpose: High pulse wave velocity (PWV), a marker of increased arterial stiffness, and an exaggerated exercise blood pressure (EEBP) response during an exercise test have both been related to an increased risk of hypertension and cardiovascular events. Contradictory results have been published about the association between these two parameters, and their relation in healthy young adults is unknown. Materials and methods: This study consisted of 209 young adults (mean age 38 years) who participated in the ongoing Cardiovascular Risk in Young Finns Study between 2007 and 2009. We measured resting PWV with impedance cardiography in 2007, and participants performed a maximal cardiopulmonary exercise test with blood pressure (BP) measurements at rest, during exercise and during recovery in 2008-2009. Results: High PWV (≥age- and sex-specific median) at baseline was associated with EEBP (SBP >210 mmHg for men and >190 mmHg for women) an average of 14 months later and with systolic BP during different stages of exercise from rest to peak and recovery (during peak exercise, β ± SE was 4.1 ± 1.1, p  < 0.001). The association between high PWV and systolic BP remained after adjustment for traditional cardiovascular risk factors and other exercise parameters (during peak exercise, β ± SE was 2.3 ± 1.1, p  = 0.04). Conclusions: Increased arterial stiffness predicts EEBP during a maximal exercise test in young adults during all stages of exercise from rest to peak and recovery. PWV could provide an additional tool for EEBP risk evaluation.
