ABSTRACT Prior research has suggested that delay or avoidance of cardiovascular disease and cardiovascular disease risk factors plays an important role in longevity.
We studied 1697 Framingham Heart Study (FHS) offspring members 30 years or older, whose parents (1) participated in the original FHS cohort and (2) achieved age 85 years or died before January 1, 2005. Offspring participants (mean +/- SD age, 40 +/- 7 years; 51% women) were grouped according to whether neither (n = 705), one (n = 804), or both parents (n = 188) survived to 85 years or older. We examined offspring risk factors at examination cycle 1 (1971-1975) including age, sex, education, cigarette smoking, systolic and diastolic blood pressures, total-high-density lipoprotein cholesterol ratio, body mass index, and Framingham Risk Score. Participants returning for examination cycle 3 (1983-1987; n = 1319) were eligible for inclusion in longitudinal analyses evaluating risk factor progression from baseline to a higher follow-up risk category.
For all factors studied, except body mass index, we observed statistically significant linear trends for lower offspring examination 1 risk factor levels with increasing parental survival category. The mean Framingham Risk Score was most favorable in offspring with both parents surviving to 85 years or older and was progressively worse in those with one or no long-lived parent (0.55, 1.08, and 1.71, respectively; P value for trend, <.001). Longitudinally, offspring of parents who lived longer had lower risk of blood pressure and Framingham Risk Score progression.
Our findings suggest that individuals with long-lived parents have advantageous cardiovascular risk profiles in middle age compared with those whose parents died younger. The risk factor advantage persists over time.

    ABSTRACT: Background Non-diabetic offspring from long-lived parents benefit from lowered CV risk. No study investigated the effects of parental lifespan on their progeny when offspring have T2DM. This study assessed CV and metabolic features of T2DM offspring according to parental lifespan. Patients & Methods 558 T2DM questioned on parental longevity (paternal and/or maternal lifespan ≥ 80 years); mean age 66 (11) years; male:female 66:34; divided into 6 groups: long-lived father [LLF] (n = 143); short-lived father [SLF] (n = 262); long-lived mother [LLM] (n = 229); short-lived mother [SLM] (n = 176); long-lived father and long-lived mother [LLF & LLM] (n = 82); and short-lived father and/or short-lived mother [SLF &/or SLM] (n = 323). Results Age was similar in [LLF & LLM] and [SLF &/or SLM]. Diabetes duration was longer in [SLF &/or SLM] (p 0.0073). Body composition, hypertension, hepatic steatosis and metabolic syndrome (MetS) were similar in both groups, [SLF &/or SLM] having a higher MetS score: 3.79 (1.12) vs. 3.48 (1.12) (p 0.0257). Fasting insulinemia was higher in [SLF &/or SLM] (p 0.0001), who were more insulin resistant (+ 10%: p 0.0440). HbA1c was higher (+ 0.36%) in [SLF &/or SLM] (p 0.0138). LDL-C; non-HDL-C; and apoB100 were similar in both groups, whereas HDL-C and apoA-I were higher in [LLF & LLM] (p 0.0233 and p 0.0179). Prevalence/severity of atherogenic dyslipidemia were raised in [SLF &/or SLM], by 53% (prevalence) and 13% (log[TG]/HDL-C) (p 0.0172 and p 0.0067). Conclusion Bilateral reductions in parental longevity are linked to unfavorable cardiometabolic phenotype in T2DM descendants, with worsened insulin resistance and atherogenic dyslipidemia among 1st-degree offspring.

    ABSTRACT: Centenarians and their offspring are increasingly considered a useful model to study and characterize the mechanisms underlying healthy aging and longevity. The aim of this project is to compare the prevalence of age-related diseases and telomere length (TL), a marker of biological age and mortality, across five groups of subjects: semisupercentenarians (SSCENT) (105-109years old), centenarians (CENT) (100-104years old), centenarians' offspring (CO), age- and gender-matched offspring of parents who both died at an age in line with life expectancy (CT) and age- and gender-matched offspring of both non-long-lived parents (NLO). Information was collected on lifestyle, past and current diseases, medical history and medication use. SSCENT displayed a lower prevalence of acute myocardial infarction (p=0.027), angina (p=0.016) and depression (p=0.021) relative to CENT. CO appeared to be healthier compared to CT who, in turn, displayed a lower prevalence of both arrhythmia (p=0.034) and hypertension (p=0.046) than NLO, characterized by the lowest parental longevity. Interestingly, CO and SSCENT exhibited the longest (p<0.001) and the shortest (p<0.001) telomeres respectively while CENT showed no difference in TL compared to the younger CT and NLO. Our results strengthen the hypothesis that the longevity of parents may influence the health status of their offspring. Moreover, our data also suggest that both CENT and their offspring may be characterized by a better TL maintenance which, in turn, may contribute to their longevity and healthy aging. The observation that SSCENT showed considerable shorter telomeres compared to CENT may suggest a progressive impairment of TL maintenance mechanisms over the transition from centenarian to semisupercentenarian age.

    ABSTRACT: A change in the lipoprotein profile is a metabolic hallmark of aging and has been the target for modern medical developments. Although pharmaceutical interventions aimed at lipid lowering substantially decrease the risk of cardiovascular disease, they have much less impact on mortality and longevity. Moreover, they have not affected death from other age-related diseases. In this review we focus on high density lipoprotein (HDL) cholesterol, the levels of which are either elevated or do not decrease as would be expected with aging in centenarians, and which are associated with lower prevalence of numerous age-related diseases; thereby, suggesting a potential HDL-mediated mechanism for extended survival. We also provide an update on the progress of identifying longevity-mediating lipid genes, describe approaches to discover longevity genes, and discuss possible limitations. Implicating lipid genes in exceptional longevity may lead to drug therapies that prevent several age-related diseases, with such efforts already on the way.
