We normalized and conducted quality control for the methylation data prior to uploading data to the calculator, but we used normalization method implemented in the calculator, as well. They also had a lower probability of engaging in regular LTPA compared to the other groups; however, they were of normal weight, on average. The DunedinPoAm estimator differs from its predecessors in that it has been developed to predict the pace of aging (Belsky et al., 2020). Z., Bandinelli, S., Vinkers, C. H., Vermetten, E., Rutten, B. P. F., Geuze, E., Okhuijsen-Pfeifer, C., van der Horst, M. Z., Schreiter, S., Gutwinski, S., Levine, M. E. (2022). In line 447, the authors argue that their results suggested that the accumulation of multiple unhealthy lifestyle habits in adolescence has a more detrimental effect on biological aging than any single lifestyle habit. The model parameters were estimated using the full information maximum likelihood (FIML) method with robust standard errors. Kankaanp, A., Tolvanen, A., Saikkonen, P., Heikkinen, A., Laakkonen, E. K., Kaprio, J., Ollikainen, M., & Sillanp, E. (2022). In the sibling comparison, we observed an increased risk of psychiatric disorder during the first year after CVD diagnosis (hazard ratio [HR], 2.74; 95% confidence interval [CI], 2.622.87) and thereafter (1.45; 95% CI, 1.421.48). Under an Emax model, we estimate the currently recommended 300 mg dose in a 60 kg adult (5 mg/kg) results in 70% of the maximal obtainable hypnozoiticidal effect. When measured with the DunedinPoAm estimator, the class had, on average, 34 weeks/calendar year faster pace of aging, and when measured with the DunedinPACE estimator, it had 45 weeks/calendar year faster pace of aging.

Our results suggest genetic correlation between adolescent lifestyle and biological aging; individuals who are genetically prone to unhealthy lifestyles or overweight in adolescence are also susceptible to faster biological aging later in young adulthood. Genetic and environmental influences on biological aging in common with lifestyle behavior patterns were studied using quantitative genetic modeling. We refer to a systematic review conducted by Whitaker and colleagues in the three consecutive sentences. We hypothesize that these cycles are driven by pre-existing antibody responses blunting responses to antigenically similar pathogens (by preventing infection and/or robust antibody responses upon infection), leading to reductions in antigen specific responses over time until individual's increasing risk leads to an infection with an antigenically distant enough virus to generate a robust immune response. in a total of five years through programs such as Early Acceptance (EA) and Accelerated Bachelors-to-Masters The second aim is to investigate whether the identified behavioral subgroups differ in biological aging in young adulthood and whether the associations are independent of baseline pubertal development. se-lective advantage.

These changes might predispose individuals to premature death in later life.. WebThe phrase time is brain emphasizes that human nervous tissue is rapidly and irretrievably lost as stroke progresses and that therapeutic interventions should be emergently pursued. We have now included it in the manuscript, and hopefully, that makes the description of the analysis easier to follow. The association between cardiovascular disease (CVD) and selected psychiatric disorders has frequently been suggested while the potential role of familial factors and comorbidities in such association has rarely been investigated. ), Sigrid Juselius Foundation (J.K. and M.O. In Finland in the late 1990s, when members of the FinnTwin12 cohort were adolescents, alcohol use was increasingly drunkenness-oriented among 14-18 year-olds (Lintonen et al., 2000). These questions remain central to both continental and analytic philosophy, in phenomenology and the philosophy of mind, respectively.. Consciousness Moreover, the correlations between PCA-based age estimates and chronological age were even weaker than obtained with the original clocks (based on Horvath 0.13 vs. 0.17, Hannum 0.06 vs. 0.10, PhenoAge -0.07 vs. 0.03, and GrimAge 0.06 vs. 0.14). It is concluded that (e.g. The experiments performed by Kankaanp et al. DNAm GrimAge is a composite biomarker comprising seven DNAm surrogates for plasma markers and smoking pack-years, which can predict the time to death (Lu et al., 2019). We have now calculated the epigenetic age estimates using principal component (PC)-based epigenetic clocks (PCHorvath, PCHannum, PCPhenoAge and PCGrimAge) created by Levines group (Higgins-Chen et al., 2022). To the best of our knowledge, this is also the first study reporting the association between adolescent BMI (relative weight) and biological aging in later life. WebThe broad expertise of our faculty allows diverse emphasis in cellular, molecular, developmental, environmental, and evolutionary biology, genetics and genomics, bioinformatics, healthy aging, marine, and organismal biology. Epidemiological studies of life course have indicated that exposures during early life have long-term effects on later health (Kuh et al., 2003). However, for the relationship to be causal, it is necessary that there are shared environmental influences on the phenotypes (de Moor et al., 2008).. also showed that shared genetic factors explained both unhealthy lifestyles and accelerated biological aging. Moreover, the unhealthiest group had, an average, 23 weeks/calendar year faster pace of biological aging, as measured with DunedinPoAm. They had normal weight, on average, and were more likely to engage in regular LTPA compared to the other groups; most of them were non-smokers and did not use alcohol regularly. DNAm was determined and biological aging was assessed for 847 twins, out of which 824 twins had also information on lifestyle-related habits in adolescence. Could the authors comment on how they think about his, i.e. However, our study also has some limitations. Please submit a revised version that addresses these concerns directly. The pace of aging describes longitudinal changes over 12 years in several biomarkers of organ-system integrity among same-aged individuals.

Western philosophers since the time of Descartes and Locke have struggled to comprehend the nature of consciousness and how it fits into a larger picture of the world. We did not conduct comparisons of the effects of the single lifestyle habits vs. the effect of overall lifestyle on biological aging. Academia.edu no longer supports Internet Explorer. WebInter-disciplinary perspectives. Another sentence on this or a DAG would help here. Our findings advance research on biological aging by showing that a shared genetic background can underlie both adolescent lifestyle and biological aging measured with epigenetic clocks. We used TYPE=MIXTURE COMPLEX option of the ANALYSIS command in conjunction with the CLUSTER=family option of the VARIABLE command in Mplus (Muthn & Muthn, 1998-2018). This might also The mean age (SD) of the twins having information on biological aging was 22.4 (0.7) years. Western philosophers since the time of Descartes and Locke have struggled to comprehend the nature of consciousness and how it fits into a larger picture of the world. The function implemented in the calculator also makes some quality checks (produces predicted sex and tissue) that help to identify suspicious samples. show that unhealthy lifestyles during adolescence may lead to accelerated aging in early adulthood. 1,2 This general call to action in acute stroke care was adapted from its predecessor in acute coronary care (time is muscle), 3 both tracing their lineage to Benjamin Franklins original Prop 30 is supported by a coalition including CalFire Firefighters, the American Lung Association, environmental organizations, electrical workers and businesses that want to improve Californias air quality by fighting and preventing wildfires and reducing air pollution from vehicles.

BMI (kg/m2) was calculated based on the measured height and weight. These decisions are dolled out in a typically binary fashion, with no expectations Moreover, boys were asked questions about the development of facial hair and voice change, while girls were asked about breast development and menarche. In line 447, the authors argue that their 'results suggested that the accumulation of multiple unhealthy lifestyle habits in adolescence has a more detrimental effect on biological aging than any single lifestyle habit'. To fully understand the role of adolescence physical activity in later biological aging would require a more comprehensive analysis of activity patterns, intensities and modes, as well as subgroup analyses that account for other lifestyle factors, such as diet'. To fully understand the role of adolescence physical activity in later biological aging would require a more comprehensive analysis of activity patterns, intensities and modes, as well as subgroup analyses that account for other lifestyle factors, such as diet. The first-generation clocks, Horvaths and Hannums clocks, were trained to predict chronological age (Hannum et al., 2013; Horvath, 2013), whereas the second-generation clocks, such as DNAm PhenoAge and GrimAge, are better predictors of health span and lifespan (Levine et al., 2018; Lu et al., 2019). We have briefly mentioned this in the end of the statistical analysis section (lines 304-305). The different normalization methods have different purposes. "Sinc Edward O. Wilson, Pellegrino University Professor, Harvard University, Journal of Archaeological Method and Theory. Before most infants are named, they are assigned a sex based on the appearance of their external genitalia by a third party. We agree that these statements are somewhat conflicting. WebThe University of California, Santa Barbara (UC Santa Barbara or UCSB) is a public land-grant research university in Santa Barbara, California with 23,196 undergraduates and 2,983 graduate students enrolled in 20212022. what does it mean if adolescent BMI has a direct effect on adult ageing that is independent of adult BMI? Genomic DNA was extracted from peripheral blood samples using commercial kits. According to the previous literature, it is controversial whether childhood obesity has a direct effect on later health, or whether the association is fully mediated by BMI in adulthood (Park et al., 2012). A latent class analysis was conducted to identify patterns of lifestyle behaviors in adolescence, and differences between the subgroups in later biological aging were studied. NASA Astrophysics Data System (ADS) Simon, A. K.; Seipelt, E.; Sieper, J. One additional point that came up during the discussion is the use of the newly generated PCA-based epigenetic clocks created by Morgan Levine's group (https://www.nature.com/articles/s43587-022-00248-2), because this has been shown to improve the performance of some of the clocks used by the authors. (2000). This finding suggests that the observed differences in biological aging probably are fully mediated by BMI in adulthood. We have now mentioned this (lines 159-161). These tags can switch the genes on or off without changing their sequences. Adolescent lifestyle-related behaviors were self-reported and, therefore, might be susceptible to recall bias and bias through social desirability. BMI (kg/m2) was calculated based on self-reported height and weight. Conclusions: Our findings reveal the existence of long-term periodicities in individual antibody responses to A(H3N2). For this reason, the associations of smoking and alcohol use with biological aging might be difficult to disentangle. However, the differences in biological aging were only slightly attenuated when the DNAm GrimAge and DunedinPoAm estimators were used, suggesting that childhood overweight may leave permanent imprint on biological aging assessed with these measures. D.A.T.C., J.M.R. 1,2 This general call to action in acute stroke care was adapted from its predecessor in acute coronary care (time is muscle), 3 both tracing their lineage to Benjamin Franklins original For that reason, we have modified the first statement (lines 480-485): The accumulation of multiple unhealthy lifestyle habits during lifetime may have a more detrimental effect on biological aging, as well, than any single lifestyle habit. The first four clocks, namely, Horvaths and Hannums epigenetic clocks (Hannum et al., 2013; Horvath, 2013) and DNAm PhenoAge and DNAm GrimAge estimators (Levine et al., 2018; Lu et al., 2019), produced DNAm-based epigenetic age estimates in years by using a publicly available online calculator (https://dnamage.genetics.ucla.edu/new) (normalization method implemented in the calculator was utilized, as well). Results: We demonstrated a long-term periodicity (about 24 years) in individual antibody responses. AA, age acceleration. However, genetic factors shared with adolescent lifestyle explained most of the observed differences in biological aging. Data were normalized by using the single-sample Noob normalization method, which is suitable for datasets originating from different platforms (Fortin et al., 2017). A Cross-Sectional Twin Study. One additional point that came up during the discussion is the use of the newly generated PCA-based epigenetic clocks created by Morgan Levines group (https://www.nature.com/articles/s43587-022-00248-2), because this has been shown to improve the performance of some of the clocks used by the authors. The twins were participants in the FinnTwin12 study and had completed a survey about their lifestyles at ages 12, 14, and 17. We conducted a twin study with a longitudinal lifestyle follow-up during the adolescent years and measured biological aging from genome-wide DNAm data using the most recent epigenetic aging clocks. ), NIH R01AI114703 (D.A.T.C., B.Y. Also from SAGE Publishing. After additionally adjusting the model for BMI in adulthood, the differences in AAPheno and DunedinPACE between the class of participants with high BMI (C4) and those with lower BMI (C1, C2, C5) were attenuated (Table 5, M2).

Adjusting for multiple comorbid conditions, we used flexible parametric models and Cox models to estimate the association of CVD with risk of all subsequent psychiatric disorders, comparing rates of first incident psychiatric disorder among CVD patients with rates among unaffected full siblings and population controls. A more recent study showed that early-life body size indirectly predisposes coronary artery disease and type 2 diabetes through body size in adulthood rather than having a direct effect (Richardson et al., 2020). Samples of poor quality (mean detection p>0.01) were excluded from further analysis. We observed differences in biological aging between the classes characterized by adolescent lifestyle patterns in young adulthood, but the differences depended on the utilized epigenetic aging measure. At each step, the classification quality was assessed using the average posterior probabilities for most likely latent class membership (AvePP). In this case, genetic factors may affect adolescent lifestyle, which lies on the causal path to biological aging (or vice versa). Also from SAGE Publishing. The following fit indices were used to evaluate the goodness of fit: Akaikes information criterion, Bayesian information criterion (BIC), and sample size-adjusted BIC. Therefore, variation in AA measures may largely be attributable to technical variation, which is not biologically meaningful. Previous studies using twin and pedigree data have obtained moderate to high heritability estimates for age acceleration (AA) measures (Horvath & Raj, 2018). We did not conduct comparisons of the effects of the single lifestyle habits vs. the effect of overall lifestyle on biological aging. WebThe latest Lifestyle | Daily Life news, tips, opinion and advice from The Sydney Morning Herald covering life and relationships, beauty, fashion, health & wellbeing used data on the levels of DNA methylation in blood samples from 824 twins between 21 and 25 years old. Twin pairs with biological aging data on both members of the pair were used in the quantitative genetic modeling to estimate the genetic and environmental components of variance for biological aging (n = 154 monozygotic and 211 dizygotic pairs). These expansions can be linked to hypothetical language family dispersal models, including dispersal from China southwards by the Sino-Tibetan and Austronesian groups. For more details, please contact the FIMM DAC (fimm-dac@helsinki.fi). The epigenetic aging measures were screened for outliers (>5 standard deviations away from mean). However, small minorities of adolescents are classified as heavy substance users or as having multiple other risk behaviors (Whitaker et al., 2021). However, own quality control is needed, as well. "Sinc to which extent shared environmental factors explain both adolescent lifestyle and biological aging (see also answers above). The following individuals involved in the review of your submission have agreed to reveal their identity: Jenny van Dongen (Reviewer #1); Esther Walton (Reviewer #3). However, both DunedinPoAm and DunedinPACE are very recently published. found that both the individuals with higher body mass indices and those in the group with unhealthy lifestyles aged faster than those who reported healthier lifestyles. An epigenetic biomarker of aging for lifespan and healthspan. We agree that DunedinPoAm estimator is outdated. In this case, genetic factors may affect adolescent lifestyle, which lies on the causal path to biological aging (or vice versa). A recent systematic review showed that healthy habits tend to cluster during childhood and adolescence, and typically, about half of the adolescents fall into subgroups characterized by healthy lifestyle habits (Whitaker et al., 2021). Our heritability estimates are somewhat higher than previously reported for AA measures based on DNAm PhenoAge (0.33-0.41) (Jylhv et al., 2019; Levine et al., 2018) and DNAm GrimAge (0.30-0.58) (Lu et al., 2019; Lundgren et al., 2022). how much do the other variables; exercise, smoking and alcohol contribute? Moreover, the class with a high BMI included participants with advanced pubertal development, which might reflect the common genetic background underlying BMI and age at menarche (Kaprio et al., 1995). 5) Independent lifestyle effects: there are two somewhat conflicting statements. Phase of cycle was associated with the risk of seroconversion to circulating strains, after accounting for age and pre-existing titers of the circulating strains. E.g., even though any suggestions around causality should be done with extreme caution, it would be possible that genetic predictors for one trait (BMI, ageing) are on the causal pathway for the other trait. When DNAm GrimAge was used, the group with a high BMI (C4) was, on average, 1.82.4 years biologically older than the two groups with healthier lifestyle patterns (C1 and C2) (Table 5, M1). We have now removed the phrase as suggested. ), the University of Helsinki Research Funds (M.O. Both the class with the overall unhealthiest lifestyle and that with a high BMI were biologically 1.73.3 years older than the classes with healthier lifestyle patterns when DNAm GrimAge was used to assess biological aging (AAGrim). An LCA model with 18 classes was fitted. This work was supported by the Academy of Finland (213506, 265240, 263278, 312073 to J.K., 297908 to M.O. We have now briefly clarified the rationale in the Results section (lines 397-408). The proportion of the total variation in biological aging in early adulthood explained by adolescent lifestyle behavior patterns was 3.7% for AAPheno, 16.8% for AAGrim, 15.4% for DunedinPoAm, and 10.5% for DunedinPACE (Figure 4). Descriptive statistics were calculated using IBM SPSS Statistics for Windows, version 20.0 (IBM Corp, Armonk, NY), and further modeling was conducted using Mplus, version 8.2 (Muthn and Muthn, 1998). Please keep in mind, however, that readers may have the same perspective as the reviewers. FinnTwin12 Cohort: An Updated Review. From the life-course perspective, epigenetic aging measures are useful tools to assess biological aging at all ages and detect changes induced by lifetime exposures. These changes might predispose individuals to premature death in later life.. All these findings support the studies showing that childhood obesity, which tracks forward into adulthood, explains the observed associations between advanced pubertal status and worse cardiovascular health (Bell et al., 2018) and can further reflect the genetic architecture underlying BMI, pubertal development, and worse health (Day et al., 2015). acknowledges support from the Medical Research Council (MR/S004793/1) and the Engineering and Physical Sciences Research Council (EP/N014499/1).

After additionally adjusting the model for BMI in adulthood, the differences in AAPheno and DunedinPACE between the class of participants with high BMI (C4) and those with lower BMI (C1, C2, C5) were attenuated (Table 5, M2). For these measures, AA was defined as the residual obtained from regressing the estimated epigenetic age on chronological age (AAHorvath, AAHannum, AAPheno, and AAGrim, respectively). Divergent T-Cell Cytokine Patterns in Inflammatory Arthritis. Shouldn't this phrase be removed or alternatively, please explain how exactly the link between genetics and lifestyle factors was assessed. A lower BIC value indicates a better model fit. All other correlations were positive. Increasing the dose to 7.5 mg/kg (i.e. This might also The authors argue that they identified pleiotropic effects underlying BMI and epigenetic ageing. Do I understand correctly that pre-QC'd methylation -values were used? Bioinformatics, 33(4), 558560. The fourth group contained individuals with a higher body mass index based on their height and weight. The question on alcohol use at age 14 and 17 measures binge drinking, which is a different measure from the alcohol use measure at age 21-25. I wasn't sure about the 'shared with adolescent lifestyle' phrase? The proportion of variation in epigenetic aging explained by the environmental factors was evaluated similarly. However, for the relationship to be causal, it is necessary that there are shared environmental influences on the phenotypes (De Moor et al., 2008). We observed similar associations in the population comparison. Initially, we conducted LCA in the subgroup of participants with DNAm data. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp https://doi.org/10.1093/bioinformatics/btw691, Teschendorff, A.

For a subsample, blood-based DNA methylation (DNAm) was used to assess biological aging with six epigenetic aging measures in young adulthood (2125 years, n = 824). In this study, lower levels of physical activity in adolescence were closely intertwined with other unhealthy behaviors. Or could this be a power issue (although group 5 I believe was larger than group 4)? The rest of the total variation in biological aging was explained by genetic and (unshared) environmental factors unique to biological aging. The participants placed in the third class (C3, 22.8%) had lifestyle habits similar to those of the participants in class C1; however, they had a higher level of BMI in the range of normal weight for children (high-normal BMI). There were no differences when Horvaths and Hannums clocks were used to estimate biological aging. Boys were slightly over-represented in the classes that were most physically active (C1, C3) and had the highest levels of BMI (C3, C4) (percentage of boys: C1: 57.2%; C3: 51.5%; and C4: 52.7%), and under-represented in the classes with lowest levels of BMI (C2) and the unhealthiest lifestyle behavior pattern (C5) (C2: 42.7%; C5: 44.1%). https://doi.org/10.1093/bioinformatics/bts680, Calculator tutorial: https://horvath.genetics.ucla.edu/html/dnamage/TUTORIALonlineCalculator.pdf. The distribution of lifestyle behavior patterns in the subsample of participants having information on biological aging was very similar to that in the large cohort data (C1: 33.0%; C2: 16.6%; C3: 20.6%; C4: 10.1%; C5: 19.7%).

Do I understand correctly that the raw data from the 2 platforms were QC'd and normalized together? The shared genetic influences on two phenotypes may be due to several scenarios (Solovieff et al., 2013). In the original questionnaire which included Pubertal developmental scale (PDS) developed by Petersen et al., there are four response categories: 1 = growth/change has not begun, 2 = growth/change has barely started and 3 = growth/change is definitely underway, and 4 = development complete (Petersen et al., 1988). We first carried out univariate modeling to study genetic and environmental influences on epigenetic aging measures (Neale and Cardon, 1992). The reviewers provided a number of comments, mostly for providing clarity, which can be found below. This finding suggests that the observed differences in biological aging probably are fully mediated by BMI in adulthood. Although I recognize that a major strength of the current analysis is that it make use of multiple lifestyle measures that are collectively summarized in one overall measure of lifestyle, I am left wondering how much each of the individual lifestyle measures is contributing and if we are mainly looking at the effect of BMI here. The frequency of drinking to intoxication had the following classes: How often do you get really drunk? 0 = never, 1 = less than once a month, 2 = approximately once or twice a month, and 3 = once a week or more. Probably, the consequences of the unhealthy lifestyle will be seen also in the DNAm-based plasma proteins in later adulthood if unhealthy habits persist. The components of DNAm GrimAge (adjusted for age) were also obtained, including DNAm-based smoking pack-years and the surrogates for plasma proteins (DNAm-based plasma proteins): DNAm adrenomedullin (ADM), DNAm beta-2-microglobulin (B2M), DNAm cystatin C, DNAm growth differentiation factor 15 (GDF15), DNAm leptin, DNAm plasminogen activator inhibitor 1 (PAI-1), and DNAm tissue inhibitor metalloproteinases 1 (TIMP-1). Did they also examine the effects of the single lifestyle habits? We showed that the reported cycles are predictable at both individual and birth-cohort level and that cohorts show a diversity of phases of these cycles. The standard errors of the latent class models and secondary models were corrected for nested sampling (TYPE = COMPLEX). However, our approach produced results with easy interpretation. The data on health-related behaviors were collected with questionnaires and interviews. A total of 1295 twins of the FinnTwin12 cohort were examined and measured either in-person or through telephonic interviews. It is part of the University of California 10-university system. WebInter-disciplinary perspectives. We agree that BMI may have a dominant role in the extraction of the patterns. There were also clear differences between the classes in biological aging measured with AAGrim and DunedinPoAm estimators. Could the authors comment on how suited this measure is for quantifying alcohol use in this age group? Our results suggest that the unhealthy lifestyle-induced changes in biological aging begin to accumulate in early life. To investigate possible biological mechanisms, we simulated individual antibody profiles encompassing known feedbacks and interactions due to generally recognized immunological mechanisms. This finding suggests that the observed differences in biological aging probably are fully mediated by BMI in adulthood. After including the sixth class, the information criteria still showed considerable improvement, but the AvePPs for several classes were below 0.8. Most of the variation in biological aging shared with adolescent lifestyle was explained by common genetic factors. In the fifth step, a class of participants with high BMI was extracted. Smoking was self-reported and classified as never, former, or current smoker. Causal effects of lifestyle on biological aging, or vice versa of biological aging on lifestyle can also be captured in the shared genetic component (i.e. Previous systematic reviews have concluded that being overweight or obese in childhood and adolescence has a consistent impact on mortality and morbidity in later life (Park et al., 2012; Reilly and Kelly, 2011). Some of the reviewers' comments may seem to be simple queries or challenges that do not prompt revisions to the text. https://doi.org/10.36684/33-2020-1-680-686. For their analysis, Kankaanp et al. Related to this point, I wasn't sure about the interpretation around pleiotropic genetic effects? The most parsimonious model with the sufficient fit to the data was considered optimal. Tracing its roots back to 1891 as an independent teachers' college, UCSB joined Therefore, these measures probably capture aspects of biological aging that are attributed to genetic factors shared with BMI. Early rice cultivation followed two pathways towards domestication in India and China, with selection for domestication traits in early Yangtze japonica and a non-domestication feedback system inferred for proto-indica. The epigenetic aging measures were adjusted for sex, age, and baseline pubertal development prior to analysis. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp How does this compare to heritability reports in other studies? https://doi.org/10.1017/thg.2019.83, Lintonen, T., Rimpel, M., Ahlstrm, S., Rimpel, A., & Vikat, A. It is part of the University of California 10-university system. Microsoft pleaded for its deal on the day of the Phase 2 decision last month, but now the gloves are well and truly off. LTPA is associated with a lower risk of mortality and cardiovascular diseases (Li et al., 2013; Lllgen et al., 2009).
