A systematic review of leukocyte telomere length and age in adults

Abstract

Objective To provide a systematic review of the relationship between age and leukocyte telomere length (LTL) in adults.Methods Relevant studies were identified by a systematic search of Medline, EMBASE and ISI Web of Knowledge databases. Key data, such as age and LTL, were extracted from the studies along with correlation coefficients and yearly attrition rates where available. Obtained data were used to calculate weighted means and correlation coefficients.Results Overall, 124 cross-sectional studies and 5 longitudinal studies were identified. A statistically significant inverse correlation between mean age and mean LTL across cross-sectional studies was observed for both absolute (r=-0.338, p<0.0001) and relative LTL (r=-0.295, p=0.0088). From mean LTL and ages, a yearly telomere loss of 24.7 base pairs (BP)/year was estimated by weighted linear regression. Weighted means of within study correlation of age and TL and yearly telomere loss rate estimates from cross-sectional studies were also in a similar order of magnitude (-0.380 and 21.91 BP/year). The few longitudinal studies reported somewhat higher mean telomere loss rates (between 32.2 and 45.5 BP/year).Conclusion While a decrease of LTL with age is out of question, data on variation of the decrease according to sex, age and other potential determinants especially from longitudinal data are still sparse.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Leukocyte telomere length generally decreases progressively over the lifespan, with average attrition rates of 14-103 bp/year in cross-sectional studies (weighted mean 21.9 bp/year) and 32.2-45.5 bp/year in longitudinal studies (weighted mean 40.7 bp/year).

    “Leukocyte telomere length generally decreases progressively over the lifespan, with estimates of average attrition rate ranging between 14 to 103 base pairs (bp) per year (weighted mean of 21.9 bp per year) in cross-sectional studies, and between 32.2 to 45.5 bp per year (weighted mean of 40.7 bp per year) in longitudinal studies (Muezzinler et al., 2013).”
  • Some individuals maintain and may even lengthen average LTL for some periods.

    “Some individuals maintain and may even lengthen average LTL for some periods (Epel, 2012; Muezzinler et al., 2013).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
